Mon Dec 30 10:57:02 1991 Per Bothner (bothner at cygnus.com)
Mainly stuff to improve handling of TYPE_CODE_REF values.
* valops.c (value_addr): If taking the addres of a
TYPE_CODE_REF, just cast the object to the corresponding
TYPE_CODE_PTR. This yields correct C++ semantics, and
preserves the location information, which has the nice effect
that &(&R) given the location containing R.
* values.c (value_copy): Make non-static (used by value_addr).
* eval.c (evaluate_subexp_for_address): Use the default
scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
* valops.c (value_addr), eval.c (evaluate_subexp_for_address,
evaluate_subexp_with_coercion): Factor out some common
expressions into variables, for easier reading.
* findvar.c (locate_var_value): Remove code to handle
TYPE_CODE_REF - it should no longer be needed.
* valops.c (value_assign): Do a COERCE_REF on the
destination operand, for correct C++ semantics.
* valarith.c (value_x_binop): Ditto: De-reference C++
references in the arguments.
* valops.c: ANSI-fy: bcopy->memcpy, bzero->memset.
Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
* dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
* symtab.c (gdb_mangle_name): Recognize and handle
constructors specially.
* symtab.c (check_stub_method): Test for failure from
cplus-demangle by calling error() instead of seg-faulting ...
Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
* defs.h: Add definition of null_cleanup()
* procfs.c: Many small changes to add base support for a new
"info proc" command (currently only printing of the address
space mapping is implemented) and allow iteration over the
address space mapping, calling an arbitrary function for each
mapping (used for shared library support).
* solib.c: Change all ifdefs that checked for "sun" to check
for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
handle locating the debug base address even when not currently
stopped at the dynamic linker entry point.
* utils.c: Add null_cleanup() as a known function that does
nothing to serve as a base for possibly long cleanup chains
with no specific "first cleanup" to serve as an anchor.
* xm-sysv4.h: Add define of SVR4_SHARED_LIBS
Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
* arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
these are all essentially the same as the versions
in ../include/opcode. The remaining *-opcode.h here
are not quite so obviously the same, and need study.
* arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
tahoe-pinsn.c, vax-pinsn.c: Change so these include
opcode/FOO.h (actually ../include/opcode/FOO.h)
instead of the recenntly departed opcode-FOO.h files.
* sparc-pinsn.c: Now that we're using the much tighter
opcode table in ../include/opcode/sparc.h, we shouldn't
need to sort the opcodes before dis-assembly.
* symtab.h, symmisc.c: Make cplus_struct_default be const.
* symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
* symmisc.c: Remove unused 'nfields' variable.
* buildsym.h: Add extern decl of unknown_symtype_complaint,
since it used used by partial-stab.h (included two places).
* partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
we should never hit the default case (until new stab codes
are added). Hence, we can leave the complaint in the
default case in even when DBXREAD_ONLY is off.
* partial_stab.h: Recognize a pair of N_SO stabs (one for the
directory, one for the filename proper) without peeking ahead.
* dbxread.c, mipsread.c: Because of previous change, don't need
ugly CHECK_SECOND_N_SO macro.
* buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
macro that invokes a function pointer in next_symbol_text_func.
* mipsread.c: Added comments various places to
explain what is going on.
* mipsread.c (parse_symbol): Support the new (SGI-specific?)
symbol types stStruct, stUnion, and stEnum.
Also, some fixes in the code for dealing with tags.
* mipsread.c: Change handling of startup_file_start and _end
- now just use the textlow and texhigh of a psymtab
to check if we've found the startup-file.
* mipsread.c: Replace s_idx by global cur_sdx in many places.
This is so mips_next_symbol_text can get at it.
Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
* dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
dbxread.c to symmisc and change name to add_psymbol_to_list.
Ditto for add_psymbol_addr_to_plist(). Also expand their
body to not use ADD_PSYMBOL_VT_TO_LIST.
* dwarfread.c: Remove add_psymbol_to_list() and convert usages
to the ADD_PSYMBOL_TO_LIST macro.
* ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
* partial-stab.h, symfile.h: Move definitions of the macros
ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
partial-stab.h to symfile.h. They aren't stab specific.
Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: Roll VERSION to 4.3.2.
Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
* m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
* m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
Include <opcode/FOO.h> instead of <FOO-opcode.h>.
* symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
allocated when it is needed. Until it is needed, it points
to a shared statically allocated structure.
* buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
in read_ofile_symtab to recognize two initial N_SO stabs,
and let process_on_symbol handle it. This is cleaner, more
efficient, and lets mipsread.c share the same code.
* symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
and related macros to here ...
* dbxread.c: ... from here.
* symmisc.c: Move the "overflow" handling from
ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
* dwarfread.c: Re-write add_psymbol_to_list to use
ADD_PSYMBOL_VT_TO_LIST macro.
* mipsread.c: Extend mipsread.c to handle stabs-style symbols
encapsulated in ecoff symbols. This enable full g++ debugging.
* partial-stab.h: Move the code for pre-scanning symbols
and building psymtabs to an include file, out from dbxread.c.
This way, the same code can also be used by mipsread.c.
* dbxread.c, buildsym.h: Various changes to allow some functions
to be used by mipsread.c (also some arguable stylistic changes).
* tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
since mips-tfile puts relocatable addresses into LBRAC/RBRAC
stabs.
* mipsread.c: Replace code to handle ambiguous tag blocks.
Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
at types and offsets) if a tag is a struct, union, or enum.
Still patch it later if we find out for sure.
* mipsread.c: In various ways, replace Forin's
ideo-syncratic code by code that fits better with the
rest of gdb, for both stabs-based and ecoff-based symtabs.
E.g. use end_psymtab; don't do extra passes over FDR table to
pre-partition global data; don't use external symbols to
create static/global symbols (just put them in the
misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
sort psymtabs or symtabs; use obstacks more.
* symtab.c, mipsread.c, dbxread.c, buildsym.c:
ANSIfy: Replace bcopy by memcpy, bzero by memset.
Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
* solib.c (locate_base): Fix uninitialized variable that was
causing return of random value to callee.
* config/mh-amix, config/mh-i386v4: Change to find alloca by
compiling and linking alloca.c, even when it is not strictly
required. Also arrange to link with -ltermlib rather than
-ltermcap.
* Makefile.in: Move TERMCAP definition to prior to inclusion
of host makefile fragments so it can be overridden.
Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
* xcoffread.c (read_symbol_lineno): Logic error in incrementing
symbol table entry number. (From Metin Ozisik.)
Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
* config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
so compiles with native compilers (without builtin alloca) can
pick up the version from the bsd emulation library. However, we
search the standard C library first so we don't pick up lots of
other broken stuff from libucb.a, that we *don't* want.
* configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
Change svr4 references to sysv4.
* source.c: Move declaration of external function index to
front of file so it is in scope for all references.
* utils.c (error, fatal): Make definitions consistent with
defs.h declarations (declared as "volatile void").
Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
* rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
* command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
* config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
for these SVR4 systems.
* symfile.c (symbol_file_add): When verbose is set, print
the names of files from which symbols are being loaded, as
when from_tty is true.
* solib.c: Completely reorganized (rewritten) to support
SVR4 shared libraries in a manner very close to the original
SunOS implementation. This support is expected to change and
become more general at some future time. The SVR4 version
does not yet work for attached processes, for example.
* dwarfread.c: Arrange in dwarf_build_psymtabs() for the
relocation address to be valid whether or not symbols are
being read from a shared library or an executable. Use the
relocation address recorded in the psymtab when reading
full symbol tables (in read_ofile_symtab). Ensure that the
relocated address ranges are recorded in partial symtabs.
* elfread.c: Add new function elf_interpreter() to return the
string from the ELF ".interp" section. This is the interpreter
that the kernel tries to run and feed the executable to.
Expand arguments to record_misc_function to include a type arg.
Modify elf_symtab_read() to supply the type arg, and to do symbol
relocations for symbols read in from shared libraries.
* procfs.c: Add new functions proc_base_address() and
proc_address_to_fd(), used by shared library support.
* tm-svr4.h: Add macros to support SVR4 shared libraries.
Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
* infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
unused START_INFERIOR_HOOK.
* remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
to account for slow loading from floppies.
(eb_create_inferior): New fn, from eb_start and
nindy_create_inferior.
(eb_close): Only use log_file if nonzero.
(eb_xfer_inferior_memory): If not writing, then read!
(eb_read_inferior_memory, eb_write_inferior_memory): Return length.
(eb_kill): A new no-op.
(eb_mourn_inferior): Remove breakpoints, then generically weep.
Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
* breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
miscellaneous comparisons of integer with NULL that elicit
compiler warnings about comparison of integer with pointer, when
NULL is ((void *) 0) rather than just a bare 0.
Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
* breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
while we reset it, in case of problems. Print breakpoint number
in error messages.
* buildsym.c (read_struct_type): Avoid sun3 compiler bug with
foo[--n].
* source.c (find_source_lines): If getting file mod time fails,
don't warn.
* target.c (target_xfer_memory): If errno is set, return it,
rather than EIO.
Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: infodir belongs in datadir.
Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
* symtab.h (struct fn_field): Add new fields `is_private',
`is_protected', `is_stub', making room by reducing the size of
`voffset'.
(struct fn_fieldlist): Delete the fields `private_fn_field_bits'
and `protected_fn_field_bits'.
(TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
(SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
(TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
(TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
* valops.c, valprint.c, symtab.c: All callers updated.
* buildsym.c (read_struct_type): Delete the `visibility' field
from `struct next_fnfield', and rework code so that visibility
info is stored into the fn_field directly. Also, hacked to set
TYPE_FN_FIELD_STUB for both static and normal member functions.
Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
* i386-tdep.c: Fix a problem on i386 systems where buffered code
stream access was failing to take into account the minimum size
granularity of the code section. For now, the buffering is simply
disabled. There is a similar problem in the i386 disassember code
that has not yet been fixed (FIXME).
* gmalloc.c: Use macros to hide some of the ugly casting required
in the previously applied fix for pointers with high bits set.
Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: Roll VERSION to 4.3.1.
Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
GDB-4.3 release!
* Makefile.in: Roll VERSION to 4.3
* README, TODO, WHATS.NEW, depend: Update.
* inflow.c (terminal_inferior): Avoid error msg if attached.
* gmalloc.c: Fix bug that causes malloc & free to
fail on systems where pointers have the high bit set (0x800efcf0
for example). The problem is that the difference between two
pointers is a signed integer, so the computation
(char *) 0x800efcf0 - (char *) 0
yields a negative value. The sign of the result of the modulus
operator is machine dependent for negative operands, thus it is
possible for it to end up negative. From Fred Fish.
Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
added clean-info. added some standards.text support and made it
look like our other Makefiles.
* configure.in: mark this directory target dependent. configure
now runs entirely in objdir so make existence tests and
references against ${srcdir}.
Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (enum_type, struct_type): Fixes for opaque and
anonymous enumerations, structures, and unions. Now passes all
the current gdb test suite tests.
Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.
Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
* symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
mid-line, be more careful about possibly advancing to the next line.
Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
* cplus-dem.c (cplus_demangle): Call `string_need' when
null-terminating a partially-computed string.
Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
symbol to the symbol table for each member of the enum.
* dwarfread.c (struct_type): Build a correct TYPE_NAME.
* dwarfread.c (add_enum_psymbol): New function to extract enum
member names and add them to the partial symbol table while
building partial symbol tables.
Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
* symtab.c (check_stub_method): Must allocate two extra argument
slots (one for `this', one for arglist terminator).
Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
* inflow.c (child_terminal_info): Supply missing '"' character.
* buildsym.c (define_symbol): Supply missing parenthesis.
Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
* coredep.c (fetch_core_registers): Fencepost error. Fixed by
Jay Lepreau <lepreau@cs.utah.edu>.
* inflow.c: Remember whether GDB has a terminal. Avoid switching
terminals back and forth if we don't have one.
* c-exp.y (parse_number): Zero is not an unsigned int constant!
* dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
Improve type parsing.
* buildsym.c (define_symbol, read_range_type): Add
long_kludge_name that passes the names of range types being
defined, down to where we must choose between 'int' and 'long'
variants. This fails on Sun C anyway since the compiler itself is
confused between int and long.
(read_array_type, cleanup_undefined_types): Correct the size of
array type whose element-type size isn't immediately known.
Early preparation to blow away many builtin types, building them
on the fly as needed. Don't compare types to builtin types with
==; examine the relevant fields instead.
* coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
* buildsym.c (define_symbol, case 'p'): Avoid ==.
* valops.c (value_arg_coerce): Avoid ==. Don't assume host and
target types are the same.
* valprint.c (val_print): I finally understand arrays, remove FIXME.
* symmisc.c (printpsyms_command): Reduce redundancy, and put all
addresses in GDB itself into parens for easy cleanup and diffing.
Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
* dwarfread (enum_type): Arrange for the order of enumeration
members to match the source code order; not the order in the
Dwarf information, which is explicitly reverse order.
Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
* main.c (input_from_terminal_p): Check whether GDB has a
terminal at all.
(initialize_main): Revise doc for `set editing'.
Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (struct_type): Handle structures and unions which
contain DIE's other than just member dies.
Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
* symfile.c (reread_symbols): Avoid kludging mtime_set, now that
BFD is fixed.
Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: VERSION 4.2.96.
* main.c (initialize_main): Revise command descriptions.
* command.c (show_user): `info user' -> `show user'.
* symtab.c (_initialize_symtab): Typo in `info types' desc.
* coffread.c (coff_symfile_read): Avoid select_source_symtab,
since it is not needed and can cause errors when examining ".o"s.
(read_coff_symtab, decode_base_type): Use complain, not printf.
Print symbol name, not its number.
Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
someday should go in a clipper target config file.
* symfile.c (compact_misc_function_vector): Handle empty vector.
(complain, clear_complaints, syms_from_objfile): Fix complaint
formatting.
* xcoffexec.c: Change syms_from_objfile caller.
* sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
when configured for cross debugging. FIXME, this needs a more
general solution.
Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
* mips-tdep.c (init_extra_frame_info): Float register
'i' has gdb-internal number 'FP0+i', not '32+i'.
* mipsread.c (new_symbol): Translate g++ special
symbol "$t" to "this".
Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)

compiler generated tags to include symbols beginning with '.' as
well as '~'.
* symtab.c (sources_info): Change simple printf of error message
to call to error().
Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
* doc/gdb.texinfo: remove leading comments that survived M4 but
described its role in the doc; add one more font to colophon;
strengthen disclaimer about unsupported configs.
Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
Fix bugs in C++ debugging.
* symtab.h: target_type is not used in record types.
Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
* symtab.c (lookup_member_type): Don't chain them up, just
allocate one in symbol_obstack when we need one.
(allocate_stub_method): Build stub in symbol_obstack.
(check_stub_method): Move here from values.c. Don't deallocate
stub; overwrite it.
(lookup_method_type): Gone now.
* buildsym.c: Handle g++ v1 stabs a little bit better.
Change some C++ parsing error()s to complain()ts.
* buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
structs have the same representation and work the same as far as
C++ is concerned.
* buildsym.c, symtab.c, values.c: Remove all references to
TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
* valops.c: Improve comments and indentation. Only call
check_stub_method when the stub flag is on.
* valprint.c: Fix or mark minor bugs and unportabilities.
* coffread.c (anonymous unions): Allocate a cplus structure.
* mipsread.c: Eliminate "template" types. Build new, real
types whenever we need them. Allocate cplus structures as needed.
Bulletproof the type parsing a bit more. Mark storage leaks.
(parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
on top of a partial type.
Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
* inflow.c (terminal_inferior): Check the results of ioctl's, and
print a message if any of them fail.
(terminal_ours_1): Store result of ioctl's for debugging, but
don't print (the terminal isn't ours...).
* tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
pointer.
* m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
conflicts with system header files.
Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)

{BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
redefinition warnings.
* defs.h: Reorder things so that the xm-file gets first crack
at #define's, followed by defs.h and then the tm-file.
* Makefile.in: Remove spaces after 'ignore exit code' - flags.
Late-model BSD 'make's don't cope with them.

* Makefile.in: Roll new files into various lists.
Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (struct_type): Must initialize the c++ specific
portion of union types as well as struct types, since gdb attempts
to reference the c++ specific info for both types.
Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: Roll VERSION to 4.2.90.
* defs.h: Incorporate param.h into defs.h. All users changed.

* standalone.c: Fake getcwd rather than getwd.
* xm-*.h: Remove fake values of MAXPATHLEN.
* xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
* Remove gdb/hp-include. Support for HP a.out oddities should be
in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
* infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
* configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
Makefile fragments for various hosts and targets now come from
gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
other config setups.
* rs6000-pinsn.c, rs6k-opcode.h: Clean up.
* rs6k-opcode.def: Delete.
Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c: Recognize obsolete form of AT_element_list
attribute still used by at least one AT&T compiler, and possibly
more.
Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (enum_type, struct_type): Ignore names invented by
helpful compilers for anonymous structs, unions, and enums.
* c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
yy_yyv, so multiple parsers produced by SVR4 versions of yacc
can coexist in the same executable without collision.
* symtab.h: Add declaration for lookup_template_type() to kill
compiler warnings about conversions from int to pointer.
Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
* procfs.c: Move inclusion of defs.h to before param.h, as in
all the other source files that include both. This is required
to supply some typedefs that are used in files included by param.h.
* m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
skipping function prologues, ala the other cpu families (i386,
mips, m88k, etc). Add the ability to skip movm and fmovm
instructions in the prologues. Still needs support for profile
(-p compiled) prologue sequences (FIXME).
* tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
m68k prologue skipping function by default.
* tm-altos.h, tm-isi.h: Continue to use the old definition of
SKIP_PROLOGUE.
Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: Remove tdesc stuff, and extra blanks before colons.
* blockframe.c: Remove tdesc-related code. Default
FRAME_CHAIN_COMBINE.
* infrun.c: Remove tdesc-related code.
* m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
of defaultable things.

default.
* coffread.c: Remove tdesc stuff.
* tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
* xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
* source.c (open_source_file): If openp fails, try again
using just the base (non-directory) part of the filename.
This solves various annoying problems, such as when the
source was compiled with an absolute pathname - and the
source files have moved. Or if the source was compiled
using a relative pathname, it can be more convenient
to just specific the source directory to the dir command.
Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
* cplus-dem.c (munge_function_name): Add missing third arg to
instance of call to do_type().
* dwarfread.c: Changes to match new dwarf.h. Remove
AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
and AT_is_external.
Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)

`struct cplus_struct_type'. Now takes 10% less memory. Many
macros changed.
* symtab.c (init_type): Don't set fields belonging to
TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
* buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
TYPE_CODE_STRUCT.
(read_struct_type): Ditto. Also, add comments about how we can
deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
* coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
TYPE_CODE_STRUCT.
(read_struct_type): Ditto.
* dwarfread.c (struct_type): Ditto.

Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
* symfile.c: Add function compact_misc_function_vector() to
remove duplicate misc function vector entries. See comments
in source for why this is necessary/desirable.
* dwarfread.c: Add misc function type parameter to internal
record_misc_function(). Remove calls to init_misc_bunches()
and condense_misc_bunches(), these are now done in elfread.c.
* elfread.c: Add support for reading bfd canonical symbol tables
and generating misc function vector entries for global and
absolute symbols. Do calls to init_misc_bunches() and
condense_misc_bunches() where they will enclose all calls to
record_misc_function(), including those in dwarfread.c.
Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
* doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
(roffable documentation).

texi2roff conversion.
Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

Motorola 88000 port without tears, I mean without tdescs.
* m88k-tdep.c: Blow away all tdesc stuff.
Provide functions for all the frame-related macros in
tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
(examine_prologue, frame_find_saved_regs, skip_prologue): borrow
from i960-tdep.c and adapt to the function prologues on the 88k.
(read_next_frame_reg): Borrow from mips-tdep.c.
FIXME: frame_locals_address should go away.
* tm-delta88.h: Dump all the tdesc stuff.
Macros for all frame-related stuff call fns of same name.
Remove duplicated definitions. FP_REGNUM becomes same as
SP_REGNUM.
* xm-88k.h: Eliminate lots of library dependencies, now handled
in libiberty. Eliminate KDB nonsupport.
* doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
* stack.c (frame_info): Mark frameless functions.
Print locals address (FIXME, remove if same).
* blockframe.c: Comment changes, FIXME after.
* coffread.c: Even without TDESC, need to zap "@" symbols.
Don't register for wierd format names; change the names in BFD.
* alloca.c, language.c, tdesc.c: Lint.
* tdesc.c, tdesc-lib: FIXME: remove these.

Allow setting breakpoints on C++ destructors.
* valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
since it lies. Rely on callers to catch missing destructors.
* symtab.c (decode_line_1): For example (see above), here.
* buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
flags since they are no longer used.
Fixes to support C++ methods with functional parameters.
* c-exp.y (func_mod rule): Allow (and ignore) list of parameter
types in a function type.
* eval.c (parse_and_eval_type), value.h: New function,
parse_and_eval_type, is based on old code from check_stub_method.
But don't actually evaluate the cast, since that calls
value_cast(), whcih may fail. Just extract the type
from the parsed expression.
* values.c (check_stub_method): While looping through the
arguments, adjust depth *after* parameter has been handled.
Replace call and setup of parse_and_eval with new function
parse_and_eval_type.
Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
* utils.c, rem-multi.shar: Remove fixed arg count version of
concat().
* altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
Change all instances of use of fixed args concat() to variable
args concat() now located in libiberty.

* xcoffexec.c: New file for handling AIX shared libraries.
Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
* core.c: Minor rewording of message to user containing name of
(and possibly arguments to) the program that generated a core
file.
* elfread.c: Remove the register_addr() stub now that it is no
longer needed.
* procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
fetch_core_registers() function for core file support.
Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
to do_cleanups() which resulted from a previous change.

start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.

Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* Makefile.in: link with libiberty after libreadline, since
readline might want something in libiberty.
* m88k-xdep.c: Fixed the register offsets in the ptrace_user
struct for BCS 88k machines.
* xm-m88k.h: don't define USIZE if already defined.
* configure.in: Added delta88 target.
Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
* am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.

function calling code moved to m68k-tdep.c.
Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)

Complain if no auxents on .bf and .ef FCN symbols, and assume
lots of line numbers.
(init_linenos, enter_linenos): Use a sentinel at the end of the
read-in linenos, to make for a fast, safe loop-end test.
Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
* coffread.c (read_coff_symtab): coffread used to rely on the
x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
function. Two of the formats I'm using (29k and 88k) don't seem to
set it. Ths patch to fcn_last_line and (enter_linenos) is an
attempt to use the actual size of the linno table in the file to set
the number of linenos to process.
Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
* Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
are created in place, so the mv fails, then the make continues.
Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
Add C++ as a separate language.
* defs.h (enum language): Add language_cplus.
* dwarfread.c (end_symtab): Support language_cplus.
* c-exp.y: Add new struct language_defn cplus_language_defn.
Don't set c to be the default language (see main.c).
* c-exp.y (yylex): Only look for field of this if
language is C++. (First difference from C!)
* language.c: Add case branches for C++ (currently, all
the same as C). Also, add c++ to "usage" note for "set lang".
* valprint.c (typedef_print). Add case branches for C++.
* main.c (main): New way to set initial language: Look at
file extension of psymtab containing main(). (Same as we
do for symtabs, but avoid loading the symtab yet.)
* symtab.c: New routine find_main_psymtab(), used by main()
to set initial language.
* symfile.c (allocate_symtab): Move code for mapping file
extensions-> languages to new deduce_language_from_filename().
Fix a C++ problem when looking for methods in super-classes.
There was confusion between base and derived types.
* valops.c (value_fn_field): Change function interface.
* values.c: Use new value_fn_field interface.
Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)

so we can get rid of some junk.
* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
* m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
type operands, as used by branch instructions.
* gmalloc.c: Fix prototype of memcpy.

that are really static in buildsym.c.
* tm-mips.h: Add symbolic names for more registers.
* mips-xdep.c (store_inferior_registers): Use new register names.
* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
only used for core files, not ptrace. Therefore,
the KERNEL_U_ADDR hack is no longer needed.
The mapping to ptrace number is now in in mips-xdep.c.
* mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
mapping from the old REGISTER_U_ADDR), and use it
in {fetch,store}_inferior_registers.
* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
Save/restore FP regs correctly (?).
* dbxread.c: Remove duplicate define_symbol and type_synonym_name
(these had been previously moved to buildsym.c).
Hence, define_symbol becomes extern instead of static.
* buildsym.c (read_struct_type): Comment out bogus handling
of C++ operator methods. Minor hacking of reading of class
contexts. Make define_symbol non-static, so dbxread.c can call it.
Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
* mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
filename with error messages.

(symfile_init): Print file format name when unable to handle it.
(free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.

* symtab.h: Remove obsolete BLOCKLIST macros.
Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
* infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
that stop_step is 1 at bottom of main loop. I don't know why this
needs to be done, but it helps me sleep better at night.
Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
* main.c (initialize_history): Read history after reading all
init files.
Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)

linetable. Patch block stabs if defined. Shrink linetable before
allocating the symtab.
* buildsym.h: Delete line_vector* and prev_line_number. Add
global_stabs and file_stabs for xcoffread.
* dbxread.c (start_subfile): Move to buildsym. Change above calls.
* symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
* symmisc.c, symtab.c: Cope with null LINETABLEs.
* blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
* tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
tm-sparc.h: Accept fromleaf parameter.
* c-exp.y (yyerror): Pass error message if given.
* configure.in: Add rs6000 host and target.
* inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
* symfile.h (entry_point): Add.
Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
* buildsym.c: New file. Breaks out symbol-table-building routines
from dbxread.c, so they can be shared with xcoffread.c.
* buildsym.h: New file. Declarations for buildsym.c users.
* dbxread.c: Remove large chunks into buildsym.c.
* Makefile.in: Add buildsym.c and buildsym.h.
* symfile.c (syms_from_bfd): New routine.
(add_symbol_file): Call it to do the real work.
(syms_from_bfd): Initialize entry_point before calling symfile_init.
* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
* cplus-dem.c (cplus-demangle): added support for templates, static
data, and the new (correct) mangling for destructors.
* dwarfread.c: (dwarfwarn): created a varargs version of
dwarfwarn, for non __STDC__ compilers.
* c-exp.y: (yylex): added match for "template" token.
(typebase): added TEMPLATE name '<' type '>' clause, for explicit
specification of template types.
* symtab.c: (lookup_template_type): new function for finding
templates in symbol table.
(type_name_no_tag): changed to explicitly check for s/u/e at the
beginning of the symbol - if it is a template, none of these will
be there (but the name will still contain spaces.)
Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
Various fixes to improve g++ debugging.
* symtab.h: Add is_const and is_volatile flags for each method.
These are bit fields - take their space from voffset,
which shrinks to 30 bits. Since voffset is now a bitfield,
make it unsigned for portability. This changes its interpretation
slightly: Static methods now have voffset 1 instead of -1,
and virtual offsets start at 2, not 1.
* symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
since it now returns an entire magled method name, not just
the type part. This avoids some duplication.
It also allows us to correctly mangle const and volatile
methods (using the new is_const and is_volatile bit fields
mentioned above).
* valprint.c (type_print_base), values.c (check_stub_method):
Simplify by using new gdb_mangle_name.
* values.c (value_headof): Fix to correctly handle single
inheritance (actually two fixes, either of which suffices).
* dbxread.c (read_struct_type): Handle const and volatile
method specifiers.
* dbxread.c (read_struct_type): Yet one more place where
we must handle '\\' continuations.
* valprint.c (vtbl_ptr_name): Add final '\0'.
Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
* tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
short return values for sparc and 68k. Patch from Paul Eggert.
* coffread.c, coredep.c, i386-xdep.c: install patches for
SysV/386 3.2 from Mauro DePalma.
Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
* core.c (core_file_info), exec.c (exec_file_info): Print file
type. Use printf_filtered.
* valops.c (value_fetch_lazy): Avoid 0-length fetches.
Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c: Add casts to remove compiler warnings.
* tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
tm-sun3.h: Remove locally duplicated code for calling functions
in the inferior. The only differences were in the specific trap
vectors used and whether or not an fpu was present. These are
now handled by appropriate definitions of BPT_VECTOR and
HAVE_68881 respectively. Other minor obvious cleanups.
* valops.c: Correct a minor misspelling.
* utils.c: Remove local BSD/USG hacks that are now in libiberty.
* dwarfread.c: Remove prototype for dwarfwarn. Does not work
with <varargs.h>.
Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
* stack.c (frame_command): Always print. Use new
frame_select_command to select a frame without printing.
* dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
* dwarfread.c: New file for DWARF debugging format support.
* elfread.c: New file for ELF object file format support.
* procfs.c: New file for SVR4 /proc (process file system) support.
* tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
Amiga UNIX support.
* xm-svr4.h, tm-svr4.h: New files for SVR4 support.
* xm-m68k.h: New file for host machines with m68k cpu.
* Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
Add elfread.o and dwarfread.o to OBS.
* symfile.h: Add "elf" to list of supported formats in comment.
* c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
types to gdb, builtin_type_long_double, builtin_type_complex, and
builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
* infrun.c: When using SVR4 /proc interface instead of ptrace(),
call proc_set_exec_trap() to setup child to stop at first instruction.
* inftarg.c: When using SVR4 /proc interface, call proc_wait()
rather than wait().
* m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
supply_fpregset(), and fill_fpregset(), which are machine
dependent support routines for SVR4 /proc interface.
* utils.c: Add warning_setup() and warning(). Warning() behaves
the same as error() except that it returns normally rather than
jumping back to command level. Modules that don't want to call
warning() for some reason, but want to produce their own warnings,
can call warning_setup() to ensure compatibility with the way
warning() and error() deal with the terminal.
* symtab.c: Make internal errors produce more useful messages.
* tm-68k.h: Move code that is duplicated in almost every single
m68k based machine's configuration files to this common file.
Duplications in the configuration files still need to be removed
(FIXME).
* infrun.c (child_create_inferior): System V versions must call
setpgrp() with no arguments, to comply with prototyping typically
in <unistd.h>.
* munch: Add support for SVR4 style nm output.
* dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
file specific fields from the partial symbol table structure and
replace them with a pointer to private data for each different
flavor of object file reader to initialize appropriately.
Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
* xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
and previous.
* mipsread.c (fixup_undef_type): New function. If a struct /
union / enum is defined in a header file but nowhere else used,
(by typedefing, pointer referencing or declaration) the mipsread code
builds the complete tree for the structure but leaves its code as
TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
Guess its type based on the details of the members.
Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
* infrun.c (wait_for_inferior): Check return value from
find_pc_line.
Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
* infrun.c (wait_for_inferior): fix stepi/nexti that was broken
by my last edit to this routine.
Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
* tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
the values before putting them into the dummy code. (From Peter
Schauer)
Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
* configure.in: added ebmon target.

and pass it to register_addr to locate the block of registers.
* xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
* dbxread.c (read_dbx_symtab, process_one_symbol): Handle
Sequent N_FN_SEQ like everybody else's N_FN.

core-file reading code.
* core.c (get_core_registers): Avoid coredump if no .reg section.
Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
* mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
This avoids coredumps under `set print object on' in value_headof
(called erroneously by value_from_vtable_info) for `p &struct'
or `p *struct'. From Peter Schauer.
Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in: Roll version to 4.1.2.
* dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
size from BFD (but, FIXME, we don't yet read external nlists's and
convert them to internal nlists's before handling them -- we still
assume they have the same size and alignment.) Use SET_NAMESTRING
everywhere useful.
* exec.c (exec_file_command): Move dead coff-encapsulation code
to BFD.
* m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
* configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.

setting pst->texthigh.
Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)

Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
* coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
vestiges of typevectors, which were for symsegs and are no longer
used. (From a question by Eliot Dresselhaus
<dresselh@RFT30.nas.nasa.gov>).
Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
* dbxread.c, coffread.c: static-ize functions that were
gratuitiously external. (From Fred Fish.)

* dbxread.c (dbx_lookup_type): Keep doubling size of typevector
until it is large enough.

Make complaint message not C++-specific.
Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)

stop at the beginning of a new line. This fixes various problems
with for loops, nested if-else's and switch statements.
Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
* symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
between symtabs and psymtabs become ordinary error()s.
* dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
properly, making "end pc" correct in shared lib psymtabs.
(From Guy Harris <guy@auspex.com>.)
Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
* dbxread.c: Enable, but soften, const_vol_complaint.
(read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
should be file-scope, not global.
(read_struct_type): Remove ancient multiple-inheritance warning.
(read_range_type): Check base type, complain & patch if undefined.
* stack.c (frame_info): Demangle the function name in `info stack'.
(From Peter Schauer)
Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
* eval.c (evaluate_subexp_for_address): Don't use
TYPE_POINTER_TYPE directly (it might be zero if this type has
never had a pointer created before); use lookup_pointer_type.
* symtab.c (lookup_method_type): Arguments were swapped in all
callers, so fix it here. I'm amazed this worked at all!
Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
* c-exp.y, m2-exp.y: Define more yysymbols that happen to be
"bss" rather than "data" symbols, but which still conflict.
* m2-exp.y: Lint.
* coffread.c (coff_symfile_read): Use xmalloc, not malloc.
* core.c (core_files_info): Shorten output.
* exec.c (exec_files_info): Ditto.

* utils.c (parse_escape): Avoid \a due to bdead compilers.
* value.h: Declare typedef_print.
* valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
kludgey.
* nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
(Reported by Mark Peek <mark@imagen.com>.)
* solib.c (solib_map_sections): Relocate all sections, even
though only the text section's size is tracked. Mark ld_text
for eventual elimination as we generalize to N sections.
* infrun.c (wait_for_inferior): Don't check if the PC is in a
call_dummy if we were stopped by a random signal that is being
passed to the program. This produced wierd results when calling
functions in the inferior and signals (e.g. SIGALRM) were in use.
Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
* infrun.c (IN_SIGTRAMP): Not parenthesized properly.
Bugfix from Paul Eggert <eggert@twinsun.com>.

* language.c (set_language_command): Handle errors by restoring
the language string to its current state (fix from A. Beers).
* doc/gdbint.texinfo: Roll in information from README. Rearrange
"how to install" and "how to print the doc" stuff so it drops
easier into README.
* configure.in: Rename rtpc CPU to romp to match config.sub.
* README, WHATS.NEW, TODO: Update for gdb-4.1.
Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)

autoloading shared libs, copyright etc on GDB startup, clean up $_
and $__ index refs, set/show listsize and related updates to list
cmd. New host/target configs.
Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
* doc/Makefile: generate aux version-no file doc/gdbVN.m4
from main Makefile.in version definition
doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
GDB version no refs
Makefile.in (setup-to-dist): generate doc/gdbVN.m4
* doc/gdb.texinfo: merge new language-switching and lang-specific
doc by Andrew Beers
Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
* mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
compilers (which may lack stddef.h).
Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
* dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
N_WARNING are the same except for the N_EXT bit, so just use their
values alone, rather than OR-ing them with N_EXT.
Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
* mipsread.c (parse_lines): Deal with negative extended line
offsets correctly.
* c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
global symbol conflicts.
Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
* .gdbinit: Move 'set complaints' to top, so it runs even in
case we aren't debugging GDB.
* language.c (_initialize_language): Fix type check and range
check documentation strings.
* utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
language.c can use it. (Though language.c should really not be
handling warnings/errors the way it does, FIXME.)
* symtab.c (lookup_primitive_type): const lint.
Bugfix from Peter Schauer:
* source.c (lines_to_list): Make signed, to avoid comparison
going unsigned and complaining that -3 is too high for 21 lines.
* stack.c (lines_to_list): Ditto.
Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in (HFILES): Add minimon.h.
(VERSION): Roll version number to 4.0.95.
(gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
New rules for building distributions. Normal distribution
is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
one level up from here; it calls make-proto-gdb.dir to build a
directory `proto-gdb' which is an image of the release. The old
`gdb.tar.Z' rule still works too.
* config.sub, configure: Roll in latest from ..
Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
* doc/gdbint.texinfo: Reorder contents; reorganize new-host,
new-target, and new-config chapters; fix minor typos; come closer
to usual GNU markup conventions for @file @samp @code @var.
Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:

* expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
* expprint.c: Look up expression opcodes in language-specific
table, based on expression's language. Handle some Modula-2
specific opcodes.
* stack.c (frame_info): Print language of stack frame.
(select_frame): Also select language, if in auto-mode.
(get_frame_language): New subroutine.
* main.c (execute_command): Warn as language changes automatically.
* printcmd.c (ptype_command): Parse types using the language
parser, both for language-independence, and so that scopes can
be specified.
* language.h, language.c: New files for language-specific macros,
declarations, and definitions.
Misc fixes:
* main.c (main): If error() is called during early
initialization, print its message and then exit(1) from GDB.

of unusual sizes.
(_initialize_valprint): Warn about host/target size assumption;
improve long long support slightly.

hex -- let parse_and_eval_address do it.
* doc/gdbint.texinfo (Languages): Doc how to add a language.
* Makefile.in: Cope with new files and removed files.
Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
Add Andrew Beers' changes for Modula-2 support. His ChangeLog
entries are enclosed herein. Not all of these changes
have been merged into the master GDB sources -- check the
ChangeLog above here for the merge log.
Mon Jun 3 17:05:45 EDT 1991
m2-exp.y Created. Tested outside of GDB for a few days. Proper
operators were added, C specific operators and tokens
removed. yylex() revamped to some extent. Still things
missing from the grammar, such as sets.
Tested for two weeks in GDB v3.5.
Tue Jun 11 17:23:48 EDT 1991
m2-exp.y Added boolean constants TRUE and FALSE to the grammar
so they are built-in. Sort of a hack.
Fri Jun 14 12:53:51 EDT 1991
m2-exp.y Added range checking for numeric constants. Any numeric
constant is assumed to be of builtin type INTEGER unless:
(1) it is octal or hexadecimal, in which case it is a
CARDINAL; (2) it is too big to fit into an INTEGER, in
which case it is a CARDINAL.
eval.c Added simple range checking for +, -, and * on integers.
Doesn't work very well for *, since 6 * 1,000,000,000 =
1,705,032,704, which fails the simple test of result >=
first_operand, no matter in what order the operands are.
Tue Jun 18 14:11:30 EDT 1991
Broke the parser into parts, one containing the C grammar and the other
containing code to be shared by all of the grammars.
The following files no longer exist:
expread.y
expread.tab.c
The following files were added:
c-exp.y (The C grammar)
m2-exp.y (The Modula-2 grammar)
parser-code.c (Code that is shared by the above grammar)
parser-code.h
parser-defs.h
Makefile.dist Changed to reflect the above dependencies. NOTE: It is
now necessary to use the Bison compiler compiler, since it
will generate function/variable prefixes other than yy.
Tue Jun 18 16:47:49 EDT 1991
symtab.[ch] Added the external variable working_lang, than holds the
value of the current working language.
Added the ennumerated type language_mode, with the values
language_auto and language_manual, the former meaning that
GDB sets working_lang as needed, and the latter meaning
that the value of working_lang is totally under user
control.
symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
REAL, BOOLEAN and CHAR. Also added the type codes
TYPE_CODE_BOOL and TYPE_CODE_CHAR.
utils.c Added set_language_command and show_language_command to
implement the GDB support commands "set language" and
"show language".
expression.h A number of identifiers were added to the type exp_opcode
to facilitate Modula-2 builtin functions, integer
division, and array indexing.
Wed Jun 19 13:25:58 EDT 1991
language.h Added the macro STRICT_TYPE, which evaluates to non-zero
if the language specified by working_lang requires the use
of strict typing of expressions. Eventually, even this
will be able to be changed by the user.
Added the macro RANGE_CHECK, which evaluates to non-zero
if the language specified by working_lang requires the
checking of a value against the domain of its type.
Eventually, even this will be able to be changed by the
user.
language.[ch] Predicates involving types (simple_type, ordered_type,
same_type, integral_type, numeric_type, character_type,
boolean_type, float_type) are added. These predicates are
based on the current value of working_lang, and are handy
in type-checking.
Wed Jun 19 15:39:34 EDT 1991
eval.c Added the function type_array_rank which computes the rank
of an array type.
valarith.c Added the funtion value_bool, which when given a integer
value.h value (ie. struct value *) as an argument, it returns a
boolean value (ie. struct value *) true if that integer
is non-zero, and a boolean value false otherwise.
valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
will print out properly.
Wed Jun 19 16:36:34 EDT 1991
valops.c Added the function value_capitalize, which returns it
value.h argument capitalized if its argument is a lowercase
letter, or the argument unchanged if its argument is not a
letter.
valarith.c Added the function range_check_p, which returns non-zero
value.h if its value argument is between the integral bounds upper
and lower.
Added the function range_check_enum_p, which makes sure
that its value argument is a valid member of the domain of
its type argument.
Added the function range_check_range_p, which makes sure
its value argument lies between the upper and lower bounds
of its type argument, which must be a ranged type.
Added the function check_array_index, which range and type
checks an index of an array.
Added the function value_multi_subscript, which computes
array[idx1,idx2...idxN], given a value array and an array
of values representing indicies.
values.c Changed value_from_long to work with TYPE_CODE_CHAR and
unpack_long to work with TYPE_CODE_BOOL and
TYPE_CODE_CHAR.
Wed Jun 19 18:04:08 EDT 1991
symtab.c Stored pervasive types in a structure and make
lookup_pervasive_type() a lookup function that was based
on working_lang. If lookup_pervasive_type() returned
non-zero, then that value was returned (a fix, since
before it simply wouldn't return the pervasive type.)
language.h Added the macro CAST_IS_CONVERSION, which evaluates to
non-zero if the language specified by working_lang means
"conversion" when it says "cast".
valops.c Added the function value_real_cast(), which performs a
value.h *cast*, not a *conversion*, which is what value_cast()
does when it can. In particular,
value_cast(<float_type>,4) = 4.0, while
value_real_cast(<float_type>,4) = some mess.
eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
and MIN on integral types. *NOTE*: These are currently
hardcoded to work only if there are 8 bits per storage
unit. FIXME.
eval.c Made logical functions call value_bool to return a
properly typed boolean value, based on working_lang.
Thu Jun 20 11:55:27 EDT 1991
valprint.c Types now print out in a Modula-2 fashion. This works for
the cases when the type is printed out step-by-step, that
is, it doesn't work when the name of a structured type
(which includes the keyword "struct", etc.) is simply
displayed.
FIXME: Perhaps this is bad. Parts of it seem to kludgey,
since type specifications in C and Modula-2 are very
different. The C printing of a type is very recursive,
whereas in Modula-2 it is generally very simple. C has
type prefixes and suffixes, which have no real analogue in
Modula-2. Maybe type_print() should call a language
specific type printer. This is also advantageous if we
compile GDB to exclude some of the languages. We'll just
leave those functions out.
Thu Jun 20 16:57:10 EDT 1991
dbxread.c When reading the complete symbol table in (via
psymtab_to_symtab()), the number and types of function
arguments are added to a function type. define_symbol()
calls add_param_to_type() to accomplish this.
Assumption: when we come across a function definition
(N_FUN symbol with an 'f' or 'F' in the name), its
arguments will appear before another function definition.
When a function is found, a pointer to its type is placed
in the global in_function_type. Changes that
add_param_to_type() makes are to this global.
valprint.c The type of a function now includes (for Modula-2) the
types of its parameters.
eval.c Type checking and a check for the proper number of
arguments is now done for function calls. Not sure of the
impact this has on C++ member function yet.
Thu Jun 20 19:58:48 EDT 1991
valprint.c Rewrote the type printer. Broke it into two language
specific parts, adding the functions type_print_m2() and
type_print_m2_1().
An unfortunate consequence is this: if you debugging a C
program in Modula-2 mode (why?), info types does not work
well with regular expressions, since the types are printed
out in Modula-2 terminology, but stored in C terminology.
language.[ch] Added the functions new_type_last(), type_keyword(), and
type_sep() to aid in the printing of typedefs.
symtab.c Made the printing of typedefs as language independent as
possible through calls to new_type_last(), type_keyword(),
and type_sep().
Fri Jun 21 11:50:26 EDT 1991
dbxread.c Check all incoming ennumerated types. If it looks like
Modula-2's BOOLEAN type, then change the type_code of the
type to TYPE_CODE_BOOL so we can process it as a boolean
variable.
valprint.c Replaced some of the 0x%x with calls to sprintf and
hexformat() in val_print().
language.[ch] Added the function hex_to_string(), which converts its
integral argument to a hexadecimal number (format is
language based) and returns the result as a string.
Mon Jun 24 12:25:07 EDT 1991
valprint.c Some functions call type_print_1() directly, instead of
value.h using type_print(), so they can specify where (column) to
print things. Since type_print() takes care of language
dependence, that needs to be called first. Added a
parameter depth to type_print() (so it is now like
type_print_1). Changed type_print to type_print_at, and
made type_print a macro that passes a depth argument of
zero.
symmisc.c Changed all calls to type_print_1 to calls to
type_print_at.
Makefile.dist Made it possible to build GDB for a specific set of
depend languages. Do this by passing a definition for the macro
LANGS to make. LANGS should be a string containing a
space-separated list of language names (ie. LANGS="c m2").
The default is to build all languages. Note that grammar
files must follow the naming convention of <lang>-exp.y.
gdb.lang This holds the current value of the LANGS macro. It is
examined every time make is called, and is updated if
necessary.
eval.c Added #ifdef _LANG_<lang> to these files.
expread.c Still need to add them to dbxread.c and coffread.c.
main.c
source.c
symtab.c
utils.c
valarith.c
valprint.c
Mon Jun 24 16:33:11 EDT 1991
language.[ch] Added the functions hexformat_pre() and
hex_to_string_pre(), which take a prefix argument to
include in the format string. Thus, hexformat_pre("08") will
return "0x08x" (if the working language is language_c).
Made hexformat() and hex_to_string() calls to the above
with "" as the prefix argument.
am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
valprint.c, vax-pinsn.c
Changed all occurences of 0x%[0-9]*l*x in printf format strings to
calls to hexformat() and hex_to_string(). Format strings without
the leading "0x" were ignored.
depend Updated to take the above into account.
Tue Jun 25 15:27:18 EDT 1991
symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
and type_check_t to keep track of the current state of
range and type checking.
main.c Added the variables range_mode, range_check, type_mode,
and type_check to record the current state of range and
type checking. Added initialization code to main().
language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
the above variables.
Tue Jun 25 17:57:08 EDT 1991
dbxread.c process_one_symbol() updates the variable (enum language)
source_lang based on the extension of the filename
contained in the N_SO sybmol that started this symtab.
When end_symtab() is called, the value of source_lang is
put into the language field.
stack.c select_frame() sets working_lang (and possibly type_check
and range_check) to the language field of the symtab
associated with the frame that is selected if working_mode
is language_auto. If working_mode is language_manual, a
warning is printed and working_lang is not set.
language.c Added the function set_type_range(), which sets the value of
type_check and range_check (if their modes call for
automatic setting) based on the current value of
working_lang. A non-zero argument will cause the current
settings to be output.
Wed Jun 26 14:51:40 EDT 1991
eval.c Added range checks on assignment.
m2-exp.y Added the grammar for sets to the language. Currently,
these do not do anything except print an error message.
Wed Jun 26 17:01:04 EDT 1991
m2-exp.y Added the ability for parse_number() to parse negative
numbers. A global flag is set upon encountering a unary
minus. This was done to make, for example, 1 parse as a
CARDINAL, and not as an integer, per Wirth's examples in
Programming in Modula-2 ed.4.
valprint.c Added support for "set radix 2" by then setting
output_format to 't'.
eval.c Implemented range checking on subrange types. Added calls
to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
Implemented MIN and MAX for ennumerated types. The
minimum value of an ennumerated type is defined by Wirth
as the first identifier, and the maximum as the last.
m2-exp.y Made octal numbers ending with "B" be characters and those
ending with "C" be numbers, per Wirth's book. (p. 34)
Thu Jun 27 14:11:52 EDT 1991
stack.c select_frame() now only sets working_lang, it does not
notify the user. If working_mode is language_manual, then
a warning is issued once.
main.c At the end of each call to execute_command(), working_lang
is checked against the local static (enum language)
current. If they differ and working_mode is
language_auto, the new settings of language, type and
range checking are printed out.
stack.c Modified frame_info() to include the language of the
current frame in the output of "info frame".
language.[ch] Added the function language_str() which returns the name
of the current language.
Fri Jun 28 15:33:14 EDT 1991
m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
the language. INCL and DECL currently cause an error,
since sets are not implemented yet. INC and DEC are
implemented as PREINCREMENT/PREDECREMENT with one
argument, and as ASSIGN_MODIFY with two arguments.
eval.c Added type checking to the above cases.
value.h Added not_lval_constant to the lval_type ennumerated type.
not_lval_constant means that the value is a constant
value; that is 3 or 'a' or TRUE, not as in a constant
identifier. This is used to help coerce numbers such as 3
to either signed or unsigned numbers.
valops.c Added the function value_coerce_constants() which coerces
constant integers as following: if one is a constant and
the other is not, the constant's type is set to the type
of the other argument. If both are constants and one is
signed, the other is converted to a signed constant.
Sat Jun 29 17:26:29 EDT 1991
valarith.c Added a better range checker. It now checks range
(successfully) on integral operations [+-] (signed and
unsigned) for any C sized type. Still does not work well
for multiplication.)
int_in_size() returns an integer that is coerced to fit into
specified number of bytes.
Mon Jul 1 13:04:14 EDT 1991
language.[ch] Added the function binop_result_type(), which returns the
builtin (struct type *) type that would be the result of a
binop on the two values V1 and V2.
Wed Jul 3 19:22:53 EDT 1991
source.c Extended source_info() to include the source language in
the output from "info source".
Fri Jul 5 13:48:52 EDT 1991
utils.c Moved the support functions for the GDB set/show commands
dealing with language into language.c.
language.c Added the function language_info(), which displays info
about the current working language, type and range check
settings. Called via the GDB command "info language".
Added an initialization routine _initialize_language(),
that sets defaults for the language, type and range
variables and sets up the new GDB commands.
main.c Language setup moved to language.c.
depend Rebuilt.
Mon Jul 8 10:10:22 EDT 1991
valarith.c Debugged the range checker for arithmetic. Still does not
work for multiplication very well.
Mon Jul 8 12:40:37 EDT 1991
language.[ch] Added the function value_true() which returns non-zero if
its argument represents a boolean true value.
breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
check the truth of an expression.
Thu Jul 11 12:51:34 EDT 1991
language.[ch] Added the predicate structured_type(), which returns
non-zero if the argument is a structured type.
Added the predicate pointer_type(), which returns non-zero
if the argument is a pointer type.
eval.c Added the ability to do addition and substraction on
pointers and integers. This case simply bypasses the
type checker.
Thu Jul 11 14:41:42 EDT 1991
include/stab.def
Added the symbol N_DEFD (0x4a) which is a definition
module dependency that is used by the GNU Modula-2
compiler and the linker. It is not important to GDB,
except that [dbx|coff|mips]read.c should ignore these
symbols.
Fri Jul 12 16:07:00 EDT 1991
valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
0 in val_print(). Also added statements to the else part
to coerce type (argument to val_print) to a pointer type
if it is an "array of unspecified length".
valops.c Added the function value_m2_string(), which returns a
(value) value which is a constant string, whose type is
(ARRAY [0..n] OF CHAR). The length field of the type
structure is set to zero, so it will be interpreted as an
"array of unspecified length".
stack.c Moved the language/frame mismatch check to
main.c:execute_command().
main.c The working language is recorded each time
execute_command() is executed. If working lang has
changed during its execution, then the new
language/type/range info is printed out for the user. If
the working language does not match the language of the
frame, a warning is issued.
Sat Jul 13 16:16:39 EDT 1991
eval.c Moved all the type-checking stuff for operators to
language.[ch] language.c. This is so we can keep language-specific
stuff (like for what type operators are defined) in
language.c.
language.[ch] Added the function binop_type_check(), which checks to see
if its two (value) arguments are type-compatible with its
opcode argument. The opcode should represent an operation
involving an operator. Also added the macro function
unop_type_check, which calls binop_type_check with a
NULL second argument.
expprint.c Added Modula-2 operators to the op_print_tab, so info
expression.h break works correctly. Also added "op_string", which
returns the string corresponding to the (enum exp_opcode)
opcode that is its argument.
Sat Jul 13 18:26:18 EDT 1991
coffread.c Added code to record the type of function arguments with
each paricular function. Code is very similar to that
added to dbxread.c.
dbxread.c Moved add_param_to_type() to symtab.c
symtab.[ch] Added function add_param_to_type() from dbxread.c
*** NOTE: The above additions have not been tested.
Mon Jul 15 12:50:47 EDT 1991
langauge.[ch] Added the functions type_error and range_error, which work
like error() except if the type/range mode is set to
*_mode_warn, then they do not do a return_to_top_level(),
but merely print a warning.
Also changed [set|show]_[type|range]_command() to support
the new "warn" feature.
Thu Jul 18 17:50:54 EDT 1991
mipsread.c Added code to record the type of function arguments with
each particular function. Code is very similar to that
added to dbxread.c.
*** NOTE: The above additions have not been tested.
Fri Jul 19 11:19:10 EDT 1991
defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
UMIN_OF_SIZE, which when given a size of a numeric type,
return the maximum and minimum value it can hold. UMAX...
and UMIN... return the result for unsigned types.
symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
struct types. They call above macros.
dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
avoid a name conlict with the above.
c-exp.y Added range checking on numeric constants in
parse_number() for completeness.
valarith.c Made binop_user_defined_p() and unop_user_defined_p()
return 0 if working_lang is not language_c.
Thu Aug 8 14:17:22 EDT 1991
main.c
printcmd.c
breakpoint.c Documentation strings of some commands changed to
eliminate the references to the C language where
appropriate.
Tue Aug 13 15:48:03 EDT 1991
m2-exp.y Added qualified identifiers to the grammar. The semantics
are slightly different from those of the GDB operator ::
c-exp.y
m2-exp.y Added a rule to each grammar of the form: start ::= exp |
type_exp, where type_exp is any valid type expression.
expression.h
eval.c Added the opcode OP_TYPE, and an error case in eval.c.
printcmd.c Modified ptype_command() so it actually parses the input
(necessary for type expressions with scope qualifiers).
Added the function ptype_eval() which expects an
expression composed of one OP_TYPE element.
*.[ch] Replaced all occurences of parse_c_expression with
parse_expression
*.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
[End of ChangeLog entries from Andrew Beers for Modula-2 support.]
Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
Small fixes from Peter Schauer:
* infrun.c (child_attach): Lint.
* solib.c (find_solib): Handle shared libs version 2.
Small fixes from David Wood:
* xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
Small fixes:
* remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
* utils.c (wrap_here): Avoid wrap action of fputs_filtered if
chars_per_line is at maximum (user typed `set width 0'). Fix
from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
* coredep.c: include ptrace.h where necessary.
* mipsread.c(parse_lines): fix unsigned char problem that was
messing up line numbers on SGI's and possibly other MIPS based
platforms.
* infrun.c (child_create_inferior): use better test to check
return val from setpgrp().
* tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
for sgi/irix support.
Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
* mipsread.c (parse_symbol): Put non-static procedures
in the global block.

and remote-adapt. Remove encapsulated coff #define's (the
support should go in BFD, and gdb shouldn't know or care).
* tconfig/a29k-kern: Same, but for remote kernel debugging.
* tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
* tm-29k.h: Update BADMAG (though it should go away).
Allow the register definitions to be overridden in another
tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
DUMMY_SAVE_GR96, for handling kernel calling conventions
that use GR64+ rather than GR96+.
* tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
remote debugging of Ultra3 kernel. Includes tm-29k.h and
overrides various things.
* remote-mm.c (mm_attach, mm_wait): Handle attach like
child_attach does, making a clean stop in the newly attached
program.
* remote-eb.c: Lint.
* coffread.c: Make coffread independent of any particular
variant of COFF. Avoid #include-ing any particular one except
internalcoff.h. BFD now passes key values for symbol reading
as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
and the symbol masks and shifts); use them.
Remove obsolete end_of_text_addr.
* exec.c: Remove unused include files.
Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
* Makefile.in (documentation targets): Pass $(M4).
Bugfix from eggert@twinsun.com (Paul Eggert).
* stack.c (down_silently_command): Check for stack existence.
Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
* Makefile.in (VERSION): Update to 4.0.3.
Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
* core.c (core_file_command): Print frame at coredump with
its level number, by calling print_stack_frame.
* frame.h: Add selected_frame_level, print_stack_frame.
* frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
* convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
Change print_sel_frame and print_selected_frame callers to
print_stack_frame.
* dbxread.c (read_ofile_symtab): Avoid empty else clause.
* symfile.c (free_named_symtabs): Ditto.
* main.c (main): wrap_here needs an arg.
* solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
(solib_add): Avoid noise.
(solib_create_inferior_hook): Lint.
(sharedlibrary_command): Move dont_repeat to here.
* utils.c (error): Call wrap_here to force buffered output.
Small patches from Peter Schauer:
* coffread.c (start_symtab): Free any existing line_vector before
malloc-ing new one.
(read_coff_symtab): Ditto for type_vector.
* source.c (lines_to_list): New variable, replacing function.
(all uses): Use as variable.
(_initialize_source): Add 'set listsize' and 'show listsize'.
* utils.c (lines_to_list): Remove function.
* stack.c (print_frame_info): Use as variable.
* defs.h (lines_to_list): Remove declaration.
Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
* breakpoint.c (insert_breakpoints): Restore warning about
the program might be running in another process, but only for
systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
* xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
* utils.c (error): if error_pre_print is set, print the string
first.
* main.c (main, print_gnu_advertisement, print_gdb_version):
Reformat legalese so it always prints, but acts as an "I'm here"
message while symbols are being read. If any errors occur,
print a few newlines to set off the message and start it at the
left margin. Remove mention of "help" command, and don't yak
about symbol reading.
(catch_errors): Error string is now printed first in case of
error, not last.
* command.c (undef_cmd_error, lookup_cmd): On undefined command,
suggest the "help" command.
* Makefile.in (VERSION): Set to 4.0.2.
Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
* .gdbinit: Remove useless "rr" command. Set complaints
to 1 for people debugging gdb.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.
Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
* WHATS.NEW: "history write -> history save". Doc "write on/off".
(Fix from kenc@viewlogic.com.)
Fix some infrastructure to be able to cope with host and target
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* values.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* doc/gdb.texinfo ($_, $__): Describe types of these variables.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
* Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
by adding .NOEXPORT target.
Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
* GDB-4.0 release!
* Update README.
* Makefile.in (VERSION): Roll to 4.0.
(gdb.tar.Z): Make refcard.ps as well, for shipment.
Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
more on printsyms.
* doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
"gdb-all.texinfo"
* doc/rdl-apps.texi: renamed from rdl-apps.texinfo
* Makefile.in, doc/Makefile, doc/gdb.texinfo:
reflect above name change
* WHATS.NEW: correct pointer to refcard.
* doc/gdb.texinfo: update New Features, Installing
* doc/gdbint.texinfo: add short description of configure +template
Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/gdb.texinfo: update, fix bugs in "Installing" appendix
Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
* Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
tar file, add dependencies for referenced doc files.
Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
* coffread.c, symfile.c, stack.c: saberized.
Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/refcard.tex: permuted Essential Commands sec
* doc/gdb.texinfo: new C++ chapter; revised installation appendix;
new doc for
set/show symbol-reloading
default set complaints 0
info all-registers
RET-repeat disabled after prompted long displays
processID (attach) interpretation of 2nd GDB cmdline arg
Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
* expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
breakpoint.c, main.c: lint.
Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
Install new configuration scheme for GDB and friends.
* config.sub: Translate ordinary names to three-part names.
* configure: Use three-part names internally.
* configure.in: Translate three-part names to filenames.
* README, WHATS.NEW: Update for gdb-4.0.
* Makefile.in: Roll VERSION to 3.99.
Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
* infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
* i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
to single structures rather than arrays; when passing
their address, use &. This avoids trouble with bdead compilers.
* mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
instead. This avoids portability headaches.
* mips-tdep.c (mips_do_registers_info): Only print FP regs if
asked to.
* source.c (open_source_file): Avoid ANSI const bdeath by
skipping declaration and then casting result value.
* tm-hp300bsd.h: Clarify comment.
* utils.c (strstr): Result is const char *; ANSI bdeath.
* xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
since system include file defines it differently from "defs.h",
though the two are equivalent for our purposes.
* tconfig/hp300bsd: Add m68k-tdep.o.
Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
* tconfig/sun*4: Remove warnings about system assembler.
Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
* mcheck.c: Avoid warning about undeclared abort fn.
* tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
it causes recursive calls to error() when used in cleanups.
To do so requires that we make it a function, so we do.
* sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
* utils.c (do_cleanups): Remove the current cleanup from the
chain *before* calling it, in case error() is called from it.
The result won't be pretty, but won't be an infinite loop either.
Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
* dbxread.c (read_struct_type): Grok anon structs for C++.
(vb_name, vptr_name): Null terminate these strings.
Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
Minor bug fixes from BSD Net2 gdb:
* blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
returns 0, there is no previous frame.
* breakpoint.c (commands_command): If !from_tty, don't call
input_from_terminal_p().
* dbxread.c (record_misc_function): Speed up slightly.
(compare_psymbols): Ditto.
* infcmd.c (do_registers_info): Take a second argument to
determine whether to print float registers. "info registers"
does not do so anymore. "info all-registers" does, now.
* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
arg and ignore it.
* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
* inflow.c (initialize_inflow): Set tflags_ours correctly.
Other fixes:
* breakpoint.c (bpstat_do_actions): Use a cleanup to restore
executing_breakpoint_commands if we are interrupted by error.
* coffread.c (init_lineno): Avoid problem with zero-sized linetab
versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
* core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
catch_errors() so we can setup the frame regardless of whether
the shared libs work.
* ieee-float.c (double_to_ieee_extended): Get exponent from
right place in little-endian systems. From John Carey.
Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
* main.c: Remove unused terminating_signals and catch_termination().
(long_options): Terminate with a zero element.
[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
(gdb_readline): Make call-compatible with readline.
(init_signals): Improve comments re vfork vs. signal.
* utils.c (prompt_for_continue): Use new gdb_readline().
If we prompt for continuation, we don't let CR repeat the previous
command, once we get back to a prompt. It's too easy to keep
hitting CR, expecting "--more--" prompts, and have some long
command start repeating on you.
Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
* blockframe.c (frameless_look_for_prologue): Speed up by
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
Define two variants, one faster.
* sparc-tdep.c (sparc_frame_chain): Use target_read_memory
and return zero, rather than giving an error.
(setup_arbitrary_frame): Initialize the PC in the new frame.
(skip_prologue): Add a second arg saying whether we're just
checking for a frameless function or not.
* core.c (core_open, core_close, core_xfer_memory): Move
section table pointers and bfd* into the target_ops.
(core_open): Allow errors in shared lib reading, etc.
(core_files_info): Describe shared library sections.
* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
exec_files_info, set_section_command): Move section table
pointers and bfd* into the target_ops.
(add_to_section_table): Add BFD to section table.
* target.c (target_xfer_memory, target_info): Pass target to
xfer_memory and target_info functions.
* target.h: ''
* gdbcore.h: Move struct section_table.
* target.h: New home of struct section_table.
* solib.c (solib_add): New argument is the target_ops whose
section list is to be added to, if any. Reallocate the
sections in that target to add any that come from shared libs.
(throughout) so_sections renamed to sections.
(solib_xfer_memory): Deleted.
* tm-sunos.h (SOLIB_ADD): Add target argument.
(SOLIB_XFER_MEMORY): Delete.
* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
from target_ops. It's the same on all targets. Add two section
pointers to target_ops.
* stack.c (find_relative_frame): Dump ancient algorithm for
"down", just use handy "next" pointers.
(frame_command): Don't error if there is no stack; let user
set one.
* inflow.c (new_tty_prefork, new_tty): New prefork routine
modifies static state in the parent process; new_tty itself
runs in the child and modifies the child's file descriptors
to match the saved static state.
* infrun.c (child_create_inferior): Call new_tty_prefork,
fork, then new_tty.
* infptrace.c (child_xfer_memory): Add ignored target arg.
* remote-eb.c (eb_xfer_inferior_memory): ''
* remote-nindy.c (nindy_xfer_inferior_memory): ''
* remote-vx.c (vx_xfer_memory): ''
* remote.c (remote_xfer_memory): ''. Rename from
remote_xfer_inferior_memory.
* main.c (main): Only try to attach "corefile" argument if
it starts with a digit.
* symfile.c (symbol_reloading): New "set/show" variable.
(symbol_file_add): Shorten message about symbol reading.
(add_symbol_file_command): Merge with add_syms_addr_command,
since this should work on all targets now.
(stop_whining): Default to zero, to shut up complaints
about bad symbol tables on many systems.
(free_named_symtabs): Just exit unless symbol_reloading.
* xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
and add comment explaining shared library screw.
* source.c: #if defined => #ifdef.
Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
* doc/gdbint.texinfo: Improve doc on porting to new OS's.
Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/rdl-apps.texinfo: provide default readline-appendix finder
(doc/Makefile knows how to make one for local config)
* Makefile.in: use doc/Makefile for doc targets
* doc/Makefile: GDB documentation now has its own Makefile
doc/refcard.tex: renamed from "gdbrc.tex"
doc/gdbint.texinfo: add markup in "Cleanups" chapter
Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
* values.c (baseclass_addr): When reading target memory, use the
length of the basetype, not the upper type. We've only malloc'd
enough space for the basetype, leading to errors in free().
* expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
ends up as a function specially, since we know the actual type of
the pointed-to address. This (somewhat) fixes display of
expressions that include misc_function_vector names. Try `cond 1
!strcmp("a","b")' then `i b'.
* infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
The child can be proceeded from inside wait_for_inferior in
evaluating breakpoint conditions, and DO_DEFERRED_STORES was
getting skipped in that case.
* expprint.c (print_subexp): Use filtered output, since the
subroutines we call use it, otherwise the output is horribly
mangled, since output of wrappable stuff comes out late.
* Makefile.in: Bump VERSION to 3.98.1
* infrun.c (child_create_process): Use execlp to find the
shell to exec our target program. This requires some fiddling
with `environ' since there is no execlpe().
Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
Minor rearrangement of refcard permits two new make targets--
gdbrc.dvi DVI output for refcard, using CM fonts
gdbrc.ps PostScript refcard, using PS fonts
Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
* GDB-3.98 release.
* TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
* Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/gdb.texinfo: last changes for release.
Minor typo and formatting fixes; incorporated most fixes remaining from
filed mail commenting on earlier drafts.
Added warnings: pipes don't work in run command;
conditions are converse of assertions;
step over fn without debug info goes to next fn;
vars may have "wrong" values near fn entrance, exit
Added example from Kingston on printing repeated nonadjacent values
Added explicit mention that in Emacs gdb mode C-c and C-z are like
shell mode for signals
Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
doesn't sound so much like its parent "Stopping and Continuing"; also
moved entries on continue to top of section, so they don't get lost.
Improved installation directions in appendix, added manual formatting
instructions
Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
* configure.in: Remove xm.h and tm.h even if we aren't linking
new ones, so "./configure sun4; ./configure none" does the right
thing. Assume that alldeps.mak and depend are already built in
srcdir, and avoid running "make" (particularly "make depend",
which involves "gcc") from inside configure. Build Makefile
directly rather than building Makefile.conf first.
* configure: Regenerate with above changes.
* Makefile.in: Use $(BISON) to find bison. Roll VERSION
to 3.98. Revise gdb.tar.Z procedure to produce a file
called gdb-$(VERSION).tar.Z but which unpacks into a
directory called "gdb". Move non-source files out of
$(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
(depend): Don't try to do "gcc expread.y".
(expread.o): Update dependencies by hand.
Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/gdb.texinfo:
Fixed a variety of small typos that prevented info from formatting
cleanly; altered too-long heading for GPL Appendix, as discussed
w/RMS; Changed date on cover to July 91.
Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* doc/gdb.texinfo:
(1) Applied some fixes due to comments from Larry Breed (easier ones
through chapsec 5.2)
(2) Eliminated use of @footnote---had my doubts about it anyways, and
it's broken in latest texinfo
(3) Introduced *some* use of [] for optional arguments, where
explanation is not simpler by listing cmd w arg and cmd w/out arg
separately. Still not using @deffn.
(4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
couple of headings are too long. Need patches to texinfo or revision
to GPL-2.
* Partial update to README (which still needs work for this
release!): (1) use of configure corrected for new script,
(2) "make gdb.dvi" and "make gdb.info" mentioned.
Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
* symtab.c (lookup_symbol): Don't complain right off about
no debug symbols; use the misc function vector first.
(list_symbols): Use misc function vector to find symbols
that don't have debug info, and print them.
(find_pc_symtab): Temporarily avoid fatal() when psymtab
PC range doesn't match symtab PC range, as it does on the
MIPS because our symtab reading isn't perfect.
* dbxread.c (dbx_symfile_read): Make warning about
"no debug symbols" slightly nicer.
* source.c (select_source_symtab): If "main" symbol exists,
but decode_line_spec can't find line info, don't just return
a zero; try other source symtabs or give an error.
* mipsread.c (parse_partial_symbols): Sort the psymtabs by
their low addresses first, then rip through fixing high addrs.
* ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
<runene@ifi.uio.no>.
(NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
* Minor, mostly mechanical, cleanup of doc subdir for clean
makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
and gdb.info (post- texinfo2 makeinfo) generated for distribution.
Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
Mostly MIPS and general symbol-reading fixups.
* doc/gdbint.texinfo: Add documentation on symbol-reading
interface.
* mipsread.c: Remove kludges around #include "ecoff.h".
Remove redefinitions of a_magic, etc, no longer used.
(parse_symbol, ): Convert "Internal:" printfs to complain()ts.
Fix global overview comments to match symfile.c protocol.
(mipscoff_new_init): Eliminate cur_hdr if we have one.
(mipscoff_symfile_read): Eliminate unused code. Avoid
sorting all the symtabs, when all we have read here is psymtabs.
The symtabs are sorted as they are created anyway. Tell
condense_misc_bunches whether we're mainline.
(psymtab_to_symtab_1): Pass filename when recursing, to make
stack trace more informative.
(parse_partial_symbols): Assume cur_hdr as argument.
(read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
the TYPE_NAME of char *, since that's done in symfile.c.
(free_numargs, parse_symbol, add_symbol, add_block,
shrink_linetable): Declare these fns void.
(upgrade_type): Convert tree of if's to switch. Clean up
bogus "off == 0" handling with a complaint. Avoid setting
field bitpos and bitsize of array with lower and upper bounds.
Check specified bitsize of elements against their actual type's
bitsize, and complain if different. Complain about unknown
type qualifiers.
(parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
(psymtab_to_symtab_1): Print names of subsidiary files that
are being read in. FIXME, we read far too many files. This code
is not the problem, the problem is in parse_fdr where the psymtabs
are set up.
(cross_ref): Result should indicate that we used one aux entry
normally, or two if we encountered a "next" entry. This used
to leave the caller pointing at the wrong aux entry.
(add_symbol): If overflowed cur_block, reallocate it larger,
chase all pointers to it, and complain(), rather than clobber memory.
(shrink_block): Use xrealloc rather than xmalloc-and-copy.
(new_field): Only allocate one field initially, not two.
Pull ++ out of macro argument. Simplify.
(_initialize_mipsread): Avoid initialization of importd
global_psymbols and static_psymbols.
* symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
to properly set pst->symtab; avoid searching for it.
(symfile_fns): Improve comments, add a FIXME.
* dbxread.c: Update comments to reflect symfile protocol.
(read_ofile_symtab, end_symtab): Return the symtab.
(psymtab_to_symtab_1): Set pst->symtab.

* cplus-dem.c: Add struct tags to a few unnamed structs.
* valops.c (value_coerce_array): Improve comments.
* valprint.c (type_print_varspec_suffix): Print array size only
if greater than zero.
* m88k-tdep.c: Shift some lines left by one space, that had
apparently been trashed at some point.
* TODO: More things to do, a few got done.
Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
* symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
(ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
comments.
* dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
* expread.y, findvar.c, symmisc.c: Ditto.
* printcmd.c (address_info): Update printed forms of LOC_
symbols. Elim LOC_EXTERNAL.
(print_frame_args): Keep track of param stack offsets before
re-looking up to find the local register param is kept in.
* mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
Further integration of mipsread into gdb. Eliminate unused
routines, duplicate declarations. Handle static symbols in
psymtabs as well as external symbols. When reading symtabs,
insert symbols into the correct block (global, static, or a local
block).
(read_mips_symtab, parse_partial_symbols): Don't pass useless
"incremental" arg.
(mipscoff_symfile_read): Don't call select_source_symtab.
(parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
rather than SYMBOL_VALUE.
(parse_external): Comment clobbering of top_stack.
(parse_partial_symbols): Update comments. Allocate and parse
static symbols as well as external symbols. FIXME, enum values
are not handled in this pass, but should be. Inline new_psymbol.
Use SYMBOL_VALUE_ADDRESS.
(psymtab_to_symtab_1): Read symbols into global static block
by default (until enter some function's local block context).
(sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
(destroy_all_symtabs, new_psymbol): Eliminate, unused.
* source.c (select_source_symtab): Select a source symtab
from either the symtabs or, failing that, the psymtabs.
(list_command): Update error message.
(forward_search_command, reverse_search_command): Use getc, not
fgetc, for speed. FIXME, add comment about buffers that die if
overrun by long line.
* values.c (unpack_field_as_long, modify_field): Avoid shifting
by an entire word, which is not portable, if we have a 32-bit
field. (Code in dbxread.c already turns such bitfields, if
aligned, into ordinary ints, but fixing this will help for other
symbol formats and for future changes.)
* core.c (core_open): Handle ANSI const brain death.
* utils.c (vprintf): Fix varargs typo.
Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
* findvar.c (find_var_value): Handle &function better.
* TODO: Document work needed on &fn and &array.
* printcmd.c (print_address_symbolic): New arg is the prefix
to print if a name is printed.
(print_address_demangle): Honor "set print address" now.
Use new arg above to improve spacing of output.
* valprint.c (val_print): When printing function pointers,
print symbolic form too.
* breakpoint.c (breakpoint_1): Use new print_address_symbolic.
Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
* core.c (memory_error): Reword error msg to mislead less.
* mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
* mipsread.c (read_mips_symtab, read_the_mips_symtab,
parse_partial_symbols): Use newer BFD internals (external_filehdr
and external_aouthdr), byte-swap the fields that we care about
before using them, and make the file header data local to
read_the_mips_symtab rather than global.
Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
* ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
* main.c (command_line_input): Flush stdout and stderr
before every call to readline. This reportedly fixes a bug
that comes up in Sys V running emacs-gdb and/or xxgdb,
when stdin/out are pipes or sockets.
Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
* configure.in, Makefile.in: Avoid rebuilding "depend" as much.
Avoid declaring Makefile dependencies, because GNU Make stupidly
tries to update it if we do.
* coffread.c: Revise for minor changes to bfd internal coff
indexes.
* configure: If -template= is given a relative path, make it
absolute before recurring in subdirectories.
* configure, configure.in, Makefile.in: Install "configure" script
as replacement for config.gdb.
* config.gdb, Makefile.dist, Makefile.sdir: Remove
* README: Update for configure, mostly. FIXME.
* Add dec3100 as equivalent to littlemips. Indicate in all host &
target config files that they are for the host. When the lines
get copied into the Makefile, this makes it more obvious what's
up.
Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
* sparc-opcode.h (trap opcodes): Avoid leading spaces or
tabs, which end up in the disassembler output inadvertently.
Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
Make it compile cleanly in an ANSI GCC2 environment.
* blockframe.c: <stdio.h>
* cplus-dem.c: free takes a void *, ifdef __STDC__
* dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
LONG_MAX/radix.
* defs.h (alloca): Avoid doing anything if alloca already def'd.
* stddef.h, stdlib.h: Remove these files.
* symtab.c: Avoid declaring qsort, close.
* symfile.c: Avoid declaring close.
* utils.c (vprintf): Declare "ap" arg as proper va_alist.
* sparc-tdep.c: Avoid including lots of Sun-host-specific files.
Assorted other changes.
* dbxread.c: include "libaout.h", not "liba.out.h".
* printcmd.c (print_frame_args): Set recurse properly for
indentation of struct and array parameters.
* valops.c (value_cast): Allow cast to void.
* infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
single_step() in a target-independent fashion.
* sparc-tdep.c (single_step): Don't call ptrace ourselves, just
set up to be ready to continue. This makes us target independent.
* infptrace.c (child_resume): Remove call to single_step; now
can single step a SPARC target of any kind.
Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
docn into separate sections---basically chapters, plus two loose
pieces that can be configured to go in different places. This
allows GNU m4 to preprocess the manual without coredumping.
* Makefile.dist: tell TeX where to find texinfo.
Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* Makefile.dist, doc/gdb.texinfo: respectively create, and use,
the new target "rdl-apps.texinfo" which captures the Makefile
variable that records where to find the Readline libraries.
Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
* tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
* tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
* defs.h (const, volatile): Only define if not already defined.
* Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
* README: Update for release 3.95.
* config.gdb: Don't create readline dir in subdir builds.
* main.c: Include with "..." form for non-system include files,
so "gcc -MM" for "make depend" works.
Include readline files with "...h" rather than <readline/...h>.
* mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
* coffread.c: Undo minor damage done by Rich Pixley. Use
different internal and external representations of COFF
data structures. Use new BFD routines for swapping them in and
out.
* symfile.c (free_named_symtabs): Avoid freeing file names that
are null or empty. Old i960 tools seem to produce files that
claim to have empty names, causing each successive file read
to blow away the previous one.
* sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
Move deferred_stores to top of file, but don't separate its
#define's from its variable. Add commentary.
* Makefile.dist: Fix Rich damage; undo "configure" changes in
favor of keeping the (working) config.gdb. Move readline
library up a notch.
Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
* dbxread.c (read_struct_type): Try to handle g++ version 1 MI
debug info.
* infptrace.c (fetch_registers): no result, since now void.
* tconfig/news: target depends on m68k-tdep too.
Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* Makefile.dist: added readline/inc-*.texinfo to dependencies for
gdb.dvi target
* readline/inc-history.texinfo, readline/inc-readline.texinfo:
applied various small fixes due to or inspired by RMS comments
* doc/gdb.texinfo: finished using all RMS comments, save those for
appendices on readline and cmd history (which are in other source
files)
Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
chapter 9; (2) documented 'break' command's menu mode for
overloaded names, in response to hgs problem report C++ p-31
Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
* doc/gdb.texinfo: (1) better introductory example; (2) more
consistent use of @code, @samp, @file, @kbd throughout; small
cleanups to first three nodes; (3) new "Contributors" node;
(4) Appendix, Renamed Commands; (5) divert specialized startup
instructions to "Targets" chapter for generic manuals, while
leaving them up front for manuals specific to specialized
environments; (6) apply fixes from RMS comments through chapter 4.
* pretex.m4: modify explanatory text slightly (and redefine
"regexp") to keep GNU m4 from complaining. (It still crashes
later, but one step at a time...)
Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
* readline/readline.c (update_line): Avoid dereferencing a pointer
before comparing it to its bounds. Saber caught this.
(init_terminal_io): Don't set BC from the "pc=" termcap variable,
and only set PC if tgetstr returned non-null. Saber caught this.
Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
* Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
stuff for config manual) here where it counts; updated
to use new subdir structure (gdb/doc/).
* Makefile: generated from above via
config.gdb none
before checkin
* gdbint.texinfo: added instructions on generating gdb.info* files
locally for release. These are ordinary info
files, formatted from gdb.texinfo (via gdb-all.texinfo, see
Makefile)---but due to use of texinfo 2, can't count on makeinfo
to generate these, so we distribute them already formatted.
* gdb.texinfo: included full Info node and menu crud (as generated
by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
* Makefile: updated "gdb.dvi" target to use M4 preprocessor;
put in comments-for-future gdb.info target (one day makeinfo will
work again).
Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
* gdb.texinfo: Updated to include new or old undocumented
commands, at least the following (perhaps some others I forgot to
record): info f, info float, info path, info program, info s, info
set, info source, info terminal, info types, info user, set/show
print object.
Also covered all recent GDB command renames for v4.
Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
* mipsread.c: Rather than keeping count of how many symtabs
and psymtabs we have, for sorting purposes, count them when
we need to sort. This fixes bug in rereading of symbol tables.
Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
* infcmd.c: renamed "info path" to "show paths"

* coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
symtab.h, target.c, target.h: Lint.
* core.c: setup and select frame after reading shared libs,
else reading shared libs will clobber them. Lint.
* utils.c (error): Force out any buffered wrap text.
Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
* remote.c: Remove decls of memory_insert_breakpoint
and memory_remove_breakpoint, no longer used. (Suggestion of
Jan Norden).
* Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
to make it easier to interface to "configure"'d libraries.
Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
* valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
aliases for set/show print.

* infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
(This still doesn't seem to make MIPS bkpts work.)
* mipsread.c: Remove dup "Reading symbol data..." msg.
(symbol_file_command, add_file_command): Remove, obsol.

* param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
or not defined. Don't define it based on TARGET_BYTE_ORDER if
it's already defined (in the tm.h file).
mips-opcode.h (BIT_FIELDS_*),
values.c (modify_field, unpack_field_as_long):
Use #if BITS_BIG_ENDIAN not #ifdef BITS_BIG_ENDIAN.

Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
Permit symbols to be superseded when new symbol files have
been read in, particularly for VxWorks.
* dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
to the main file, as well as to include files. Also, put global
functions into the global psymtab, to make "i fun" work.
(end_psymtab): Free named symtabs and psymtabs for a file, once a
new psymtab for it has been read.
* coffread.c (end_psymtab): Free named symtabs and psymtabs for
a file, once a new symtab has been read for it.
* mipsread.c: FIXME. We need to do the same for MIPS, but it
looks harder to determine the top-level block before it's been
queued to the psymtab list.
* symfile.c (symbol_file_add): Use filtered printing and wrap it.
If we have wiped out any old symbol tables, clean up at end of
symbol reading.
(symbol_file_command): Don't reference symfile_fns if it's zero.
* symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
defines for the blocks of a blockvector that contain global and
file-static symbols and the first of the smaller scope contours.
* symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
decode_line_1, make_symbol_completion_list): Use the above.

It's not perfect, but it is better than nothing.
(_initialize_symtab): Restore "info types".
Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
* m68k-stub.c: Remote stub for 680x0's, created from
rem-m68k.shar (which is removed).
* nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
Remove RCS log stuff now that we use CVS and it blows our diffs.
Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
* symmisc.c (free_named_symtab): Make it work, in its current
kludgy fashion. Change result to indicate if we blew away bkpts.
* dbxread.c (end_symtab): Accumulate result from
free_named_symtab and print warning if we blew user's state.
* symfile.h: free_named_symtab now returns an int.
Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
* dbxread.c (dbx_symfile_read): Initialize psymbol list if this
is the first symbol read, even if not mainline.
(dbx_psymtab_to_symtab): symfile might be zero, cope.
* exec.c (exec_ops): Add_syms_addr is valid in our tvec.
(set_section_command): New command ("section xxx yyy" -- should
be renamed to "set section xxx yyy" FIXME) which sets the
base address of a section of the exec file, overriding the
virtual address that BFD reports.
Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
* exec.c: Add add_syms_addr_command to exec_ops, so you can
load symbols at any address while examining an exec file.
Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
* tm-i386v.h (FLOAT_INFO): Don't define it, since the code
for printing the float info is host-dependent, not
target-dependent. FIXME.
* i386-pinsn.c: Move #includes to top, remove useless ones.
* i386-tdep.c: Don't bother including <.../reg.h> since we
don't use it (and it doesn't exist on host systems).
* ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
Convert negative numbers properly.
(ieee_test): Make numbers really random; fix format arg.
* infcmd.c (attach_command, detach_command): Don't repeat on CR.
* core.c (core_detach): Unpush core_ops, which might not be on
top. We used to just pop the top, which broke things. Don't
need dont_repeat() any more.
(core_file_command): Psst! Don't repeat it.
* remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
* expprint.c (print_subexp): Avoid switch fallthru on
BINOP_ASSIGN_MODIFY, so we can print += and such.
* frame.h: Fix typo.
* inflow.c (kill_command): After killing inferior, print our
current frame in the core file, if we have one.
(generic_mourn_inferior): When inferior dies, either select
the current frame (in the new target, e.g. core file), or
set both the current and selected frames to NULL.
Changes from Peter Schauer.
* infptrace.c: Avoid <sys/ptrace.h> on USG.
* Make all file names fit in 14 characters (sigh and damn!):

tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
names.
* command.c (user_info_1, user_info): New command for listing
the user-defined commands.
Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
* dbxread.c (really_free_pendings): Clear file_symbols
and global_symbols after freeing them; otherwise, running
this function twice (if it appears twice on the cleanup
chain), we try to free things twice.
* dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
based on text_addr (the address of text in core), not on addr (the
offset between text in the .o file and in core). This change
is from Peter Schauer.
* main.c: Define ALL_CLEANUPS as a cast of zero.
(return_to_top_level): Use it.
(main): Do all cleanups after each command run as part
of the gdb startup sequence. Also do all cleanups before
entering the command loop, and every time we exit the command
loop and reenter. Before, the cleanups from the startup sequence
were being left undone until the first error!
(command_loop): Rename do_nothing cleanup to command_loop_marker
so we can see it easily when examining the cleanup chain.
(init_signals): Add another do_nothing for signal handling.
(quit_command): Only try to kill target if it has execution.
Problems in the target stack got us into a state where
inferior_pid was nonzero but none of the targets had execution.
In this state you couldn't exit gdb.
* dbxread.c: Two changes from Peter Schauer.
(echo_command): Fflush output after an echo command.
(show_history): Pass all args to cmd_show_list.
* utils.c (init_malloc): Call mtrace to turn on tracing
if the environment variable MALLOC_TRACE is set to a file name.
* mtrace.c: Add source file which provides a log of every malloc,
free, and realloc to a trace file.
* mtrace.awk: Add source file which analyzes the trace file.
* Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
(VERSION): Roll to 3.94.3.
* breakpoint.c (breakpoint_1): Add a space to "i watch" output.
(check_duplicates): Don't bother with watchpoints.
(set_raw_breakpoint): Comment about danger of this routine.
(watch_command): Parse and eval all args before calling
set_raw_breakpoint.
* solib.c (find_solib): Avoid error in referencing memory to
see if any more shared libraries have been added. This is
particularly useful if the target has terminated. Bug reported
by Peter Schauer.
Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
in bringing up 3.94.2 on the Sun-3.
* Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
* breakpoint.c (enable_breakpoint): Check for valid watchpoint
expression (in scope) before reenabling watchpoint.
* signame.c (init_sigs): Add missing declaration of i, fix
sys_siglist declaration.
* source.c (list_command): Fixed range computation to use
lines_to_list ().
* stack.c (backtrace_command): Do not allow command if target has
no stack, print informative error message.
* target.c (target_command): Do not write into command line
because this fails if the target command is used in a user defined
command. [This change was enhanced by gnu to support any-
unique-prefix matching on target names.]
* valops.c (value_struct_elt): Avoid infinite loop on an
erroneous attempt to print the member of function (try p main.p).
Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
* expread.y (name_no_typename): Avoid reduce/reduce errors
caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
Since the GDB parser really doesn't use name_no_typename in a
name-only context, the parser can't tell the diff between
names and numbers here. Avoid allowing a name_no_typename
to be a NAME_OR_*INT to resolve the conflict.
Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
* valprint.c (val_print_fields): bitfield printing didn't handle
byte order. Indirect through a few more fns to cope.
* values.c (modify_field): also cope with byte order.
Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
Cleanup for release 3.94.2:
* Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
include files. Roll version to 3.94.2.
* coffread.c (init_stringtab): Read length into unsigned char
array before swapping; don't assume 32-bit longs.
* target.c (target_info): Don't bother with get_sym_file, just use
the symfile global variable.
* symtab.h, symfile.c (get_sym_file): Delete it.
* dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
(define_symbol): Set symbol line number to 0 if not gcc-compiled.
(read_type): Replace one more error() with complain().
* mipsread.c (parse_partial_symbols): Replace printf with complain.
* i960-tdep.c: Fix copyright attribution.
* config.gdb: Quote all backquotes in doublequotes. You can
quote me on that. BSD 4.4 shell found this one.
* infptrace.c (throughout): The third argument to ptrace is an
int *, not an int.
* infrun.c (wait_for_inferior): When program has terminated, we
have to call target_terminal_ours before we pop that target off
the stack (e.g. before a call to target_kill or
target_mourn_inferior). This fixes problem where a program
terminates, then GDB stops for (tty output) and you have to type
"fg" to the shell to resume it. FIXME: This code for what to
do after termination really should be in normal_stop instead.
* gdbcore.h (read_memory_check): Change declaration; it changed
names months ago.
* terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4.4 prereleases, this avoids a bug in their sgtty compatability
support.
* remote.c: Use terminal.h rather than hand-rolling the same.
* signame.c, signame.h (psignal): Arg is unsigned, not int.
* utils.c (strsave, strstr): Fix arg types.
* valprint.c (val_print): lint
MIPS symbol table support from Per Bothner:
* symfile.c (symtab_fns): Remove initializer table that needs to
be hacked for each new symbol file format supported.
(add_symtab_fns): New function, chains symbol table
handlers into the global list.
(symfile_init): Search this list.
* symfile.h: Add next pointer, declare add_symtab_fns.
* coffread.c (_initialize_coffread): Call add_symtab_fns.
* dbxread.c (_initialize_dbxread): Call add_symtab_fns.
* mipsread.c (psymtab_to_symtab_1): return void instead of (struct
symbol *). Thus, we no longer need the hack to trash
pst->filename. Good, since that hack confused code in symfile.c!
(reorder_symtabs, destroy_all_symtabs): Removed static
all_symtabs, which was used to qsort symtabs in reorder_symtabs.
Instead, the latter now uses a temporary array (stack-allocated
from an obstack, and then freed).
(parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
haven't been set in the outermost stBlock of a procedure. This was
a problem with f77 binaries on Ultrix 4.?.
(new_symtab, new_symbol, new_type): Continue changing code to use
obstacks more and otherwise conform to dbxread internal style.
Made the free_code of symtabs be free_linetable (as in dbxread)
instead of free_contents. This implies memory leaks when reading
a new symbol table, until the conversion is finished. Did change
(struct symbol) and (struct type) to be allocated on the
symbol_obstack. Blocks and blockvectors are among the things
still "leaking."
* mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
tested much, but it solved one problem (reported by Meissner), and
cleans up some other things. The problem happened when an
included file contains actual code (functions) and not just
definitions. The mips coff is a little inconvenient there, since
it may cause a procedure to be mapped to the wrong psymtab.
* mips-tdep.c (heuristic_proc_desc): Minor cleanup.
* mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
this will need work for the new core paradigm.
Opcode patches from the net:
* mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
missing altogether - they are added here. From Bruce Bauman.
* mips-opcode.h: The low mask for C0 instructions was too small.
From Garrett Lau. I modified the fix to check the entire 32-bit
opcode.
* ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
Bauman.
Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
* dbxread.c (read_type): Pointer subtraction (value_sub in
valarith.c) sometimes failed because the types of the
pointers being subtracted were not identical.
These differed because dbxread.c was allocating pointer types
using dbx_alloc_type+smash_to_pointer_type instead of
lookup_pointer_type. I failed to find a justification for the
former, so I changed it to use the latter. Similarly, I
replaced smash_to_function_type by lookup_function_type,
and smash_to_reference_type by lookup_reference_type.
* mipsread.c (parse_symbol, upgrade_type, parse_procedure,
_initialize_mipsread): corresponding changes.
* symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
* source.c (mod_path): Do tilde_expand on each component of the path,
rather than on the (list of) paths as a whole.
(print_source_lines): Set first_line_listed in addition to
current_source_symtab and current_source_line. If the source was
not findable, after a "dir" command to fix the problem,
a "list" would get the wrong lines.
While I was there... (gnu):
* dbxread.c (read_type): Change error to complaint.
Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
First attempt at detailed understanding of symbol table memory alloc.
* dbxread.c (dbx_symfile_read): Free our string table if we
aren't the mainline. Free the "info" struct since we're done with
it.
(init_psymbol_list): Free any previously allocated psymbol lists.
(): FIXME: Should realloc-down the psymbol lists when done reading
the main symbol file?
* symmisc.c (free_symtab): Free fullname field too.
* xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
(REGISTER_ADDR): Make result type unsigned int.
* xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
define REGEX must also define REGEX1 (its dependency).
Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
* tconfig/i960: No longer works, points you at vxworks960 or
nindy960.
* xgdb.c, XGDB-README: Remove file. Users can get the much
better xxgdb.
* Makefile.dist: Remove all trace of xgdb.
* breakpoint.c (breakpoint_1): Pass demangle arg to
print_address_symbolic.
(clear_breakpoints): Remove unused function.
(breakpoint_re_set_one): Guts of breakpoint_re_set.

directory_command, modifies a path. Used by path_command.
(directory_command): Call it.
* defs.h (strsave): Declare.

(printchar): Use it.
(strsave): Provide this handy helper routine.
(set_width_command): Rename set_screen_width_command.
(_initialize_utils): "set screen-width" => "set width";
"set screen-height" => "set height"; add sevenbit-strings.
* infcmd.c (do_registers_info): Print floating point registers
in raw hex as well as float format, regardless of whether it is
a "virtual" convertible register.
* tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
regs as a double, just in case it's being used that way.
* values.c (unpack_long): Comment on array/function coercion.
(unpack_double): Argument is in target byte order now. For
integer arguments, just call unpack_long and float the result.
* m68k-tdep.c: include defs.h for "const" handling.
* remote-nindy.c: Use ieee-float stuff.
(nindy_fetch_registers): Unpack double regs to host double, then
to extended.
(nindy_store_registers): Pack extendeds to host double, flip
around by misusing unpack_double, send as target double.
* tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
zero, as when stopped at the first instruction of a process.
* blockframe.c: Fix filename in comment (param.h => tm.h).
* sparc-tdep.c (skip_prologue): More explicit nudging comments.
* tm-68k.h: Fix typos.
Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
Changes from a bringup on the DEC Vax under Ultrix 4.0.
* coredep.c (fetch_core_registers): Pass end-address of register
section to register_addr as expected. Don't call supply_register
if we'd just pass it garbage.
* dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
* exec.c (xfer_memory): Use boolean xfer_fn result, not int.
* target.c (push_target, target_info): Cast enums to int for < or
> comparison.
* stack.c (print_frame_info): Identify source file & line
even if we can't print it.
* xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
Clean up IEEE floating point support.

* ieee-float.c: Write real routines to convert between host
doubles and various target IEEE extendeds.
* m68k-xdep.c: Eliminate assembler code for extended floats.
* xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.

REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
double_to_ieee_extended.
* i960-tdep.c: Define ext_format_i960.

* symfile.h: Add symfile_bfd, common between dbxread and coffread.
* dbxread.c: Remove static symfile_bfd.
* infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
it is not used yet.
* inftarg.c (child_detach): Pop the child_ops vector if the
detach is successful.
* remote-nindy.c (nindy_create_inferior): Don't push a new
nindy_ops since nindy uses the same one for execution and memory
examination anyway.
* core.c (core_ops): Use child_attach and child_create_inferior
rather than default attach and create_inferior functions.
Handle floating point registers in core files.
* sparc-xdep.c (fetch_core_registers): Rewrite for float support.
* sun3-xdep.c (fetch_core_registers): Rewrite for float support.
This version untested since BFD doesn't yet support sun3 core
files.
* hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
conventions. Fix comments and style. This version has not
been compiled yet, since we have no HP inhouse.
* core.c (get_core_registers): Look for two sections, ".reg"
and ".reg2", and pass both to fetch_core_registers sequentially.
Revise directory path yet again.
* source.c (forget_cached_source_info): Not static any more.
(init_source_path): New default source path is "$cdir:$cwd".
(dir_command): Handle variable arguments ($cdir, $cwd).
(source_info): Print "Compilation directory" rather than
"Originally compiled in" to remind people of $cdir.
(openp): If the path contains $cwd, use current directory.
(open_source_file): If compilation directory is known, replace
first $cdir in path with the compilation directory.
(print_source_lines): Even if we can't print the lines, set the
current symtab and line for future commands like "info source" or
"breakpoint". Also, error message now contains the file name,
line number, and file access error message.
(_initialize_source): Fix help text to describe changes.
* main.c (cd_command): Forget cached source info when we chdir.
* utils.c (strstr): Add simple implementation.
Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
* coffread.c (read_one_sym, init_linetable, init_stringtab):
Byte-swap COFF symbol tables if necessary when reading them in.
Use complain() to replace error message in one spot. Needs
corresponding change in bfd/coff-code.h to make some symbol
swapping routines non-static.
Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
Merge changes from Eirik Fuller, for UTek.
* defs.h (errno): Add declaration.
* altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

declarations of errno.
* remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
* remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
<rpc/rpc.h> and <rpc/types.h>.
Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
* i960-tdep.c (examine_prologue): Add new argument limit,
which stops the scan at the end of the prologue, or at the PC.
This fixes a problem where it walks down into the code for the
user's statements if that code looks like function prologues.
Mark Fox and I have been bouncing this code back and forth, making
small changes to it. Callers changed to match.
Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
Cleanup for gdb-3.94 release final:
* Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
the .c files from vx-share and nindy-share, from the various
macros, since they are not found via ALLDEPFILES.
(SFILES): Add tm-i960.h.
(alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
in the SUBDIR list.
(TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
(gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
* am29k-tdep.c: Add contribution line.
(examine_prologue): Cache information about function prologues in
the misc-function-vector to avoid lots of references over the
serial line while examining instructions.
* core.c (core_close): New function made from cleanup_core.
* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
remote-vx.c, remote.c, target.c, target.h,
Update target_ops vector to add attach, close, and load entries.
Use add_syms_addr_command, not add_file_addr_command, for
add_file. Break out close routine from existing code.
* dbxread.c (really_free_pendings): Don't free pending_blocks;
they are in an obstack.
(read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
Lint.
(define_symbol): Add symbol type parameter; change callers;
pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
it to influence the symbol class on the i960.
(define_symbol): Swap LOC_CONST's into target byte order.
* exec.c (exec_close): New function.
(exec_file_command): Call it.
* findvar.c (read_relative_register_raw_bytes): Doc byte order,
Fix byte order of frame pointer.
(read_var_value): Result of 0 if var's value can't be found,
e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
(locate_var_value): Use read_var_value and use its lazy address
as the location of the var's value. Lint.
* i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
instructions.
* i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
obsolete Intel versions in favor of vxgdb versions.
(check_host, byteswap, byteswap_val, reorder_val): Eliminate
code dealing with byte order of values, which Intel did in host byte
order rather than gdb-4's target byte order.
(i960_frame_chain_valid): Move to nindy-tdep.c.
(examine_prologue, skip_prologue, frame_find_saved_regs,
frame_args_address, leafproc_return, saved_pc_after_call,
pop_frame): Add vxgdb versions from Mark Fox.
(examine_prologue, frame_struct_result_address): Add code
to deal with the saved value of G13 (struct return address
pointer).
(frame_args_address): Modify Mark's version to prefer the
saved value over the current value in the topmost frame.
Cache result in the frame info to avoid performance hair in
callers.
(print_fault): Add gdb960 code for printing faults.
(_initialize_i960): Actually call check_host.
* ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
add stub routines. FIXME, these currently just return zero!
* infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
(attach_command): Call target_attach, not target_open, now.
* infrun.c (normal_stop): Make global, not static, for vx_attach.
(child_attach): Rename from child_open.
(wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
don't confuse it with a zero step_resume_break_address.
* inftarg.c (child_detach): Eliminate inferior_pid test.
(child_files_info): Clean up message a bit.
(child_ops): Use child_attach, not child_open, to attach.
* mem-break.c: #ifdef out the whole file if BREAKPOINT is not
set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
findvar.c to here, since it depends on the contents of the
shadow_contents of breakpoints, but keep if #if 0 since it is
never called.
* nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
from i960-tdep.c.
* printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
(ptype_command, display_command): Eliminate have_inferior_p and
have_core_file_p in favor of target_has_stack or
target_has_execution.
(print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
code for actually finding the values of arguments, though we still
keep track of the maximum stack offset for use in printing unnamed
arguments. Handle missing FRAME_ARGS_ADDRESS.
* remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
(struct nindy_regs): Define registers passed to/from nindy.
(nindy_fetch_registers, nindy_store-registers): Translate between
nindy and GDB formats for the registers.
(dcache_init): Statically allocate the cache, since it was being
allocated by a malloc that was never freed anyway.
(nindy_create_inferior): Error, not core dump, if no exec file.
(nindy_before_main_loop): Use target_load, not target_add_file.
* remote-vx.c (net_load): Specify large timeout for load
requests. Allow user to break out with INTERRUPT.
(net_break): Remove useless code, clean up. Change callers.
(parse-args, skip_white_space, find_white_space): Clean up arg
parsing to cope with quoted strings.
(net_wait, net_quit): Never call error, just return status.
(vx_read_register, vx_write_register): Cleanup status checking.
#ifdef the code based on which CPU we are using (960 or 68k),
FIXME, this should be completely general but it isn't yet.
(vx_xfer_memory, vx_resume): Cleanup status checking.
(vx_run_files_info): Improve message.
(vx_load_command): Renamed from vx_add_file_command. Allow load
to be interrupted.
(net_ptrace): Remove unused routine.
(vx_wait): Adopt code from vxgdb960 to cope with broken
connections to target machine and prompt to disconnect. Remove
debug printouts. Map some EVENT_'s to SIGnals.
(add_symbol_stub, vx_open): Print names of object files we found,
and "ok" if we read their symbols OK. Clarify output in general.
(vx_attach, vx_detach, vx_kill): Add these commands.
(vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
(vx_run_ops): Turn off all_mem, to avoid spurious msg in the
"info files" output, and create_inferior, since we already have
an inferior.
* stack.c (frame_info): Replace Frame_unknown with 0.
(print_frame_arg_vars): Handle LOC_LOCAL_ARG.
(return_command): Pop until the PC matches as well as the FP,
so it works even if the FP is shared with another function,
as in "frameless" or "leaf" procedures.
* symfile.c (load_command): renamed from add_file_target_command.
(add_syms_addr_command): renamed from add_file_addr_command.
(add_syms_command): Stub to call target_add_syms.
(_initialize_symfile): Change command names and descriptions,
add-file => add-syms, and load from alias to its own command.
* target.c (kill_or_be_killed, maybe_kill_then_attach,
maybe_kill_then_create_inferior): Default for attempts to start
a process, if one is already running, is to ask about killing
it and retry if yes.
(upstack_create_inferior): #if-0 it, strata obsolete it.
(push_target, unpush_target, pop_target): to_close() a target
before unstacking it.
(target_info): Renamed from target_files_info.
(_initialize_targets): Rename "i files" as "i target", accessible
under both names.
* target.h: Improve comments about the target_ vectored routines.
* tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
Convert commenting style to standard GNU style.
(DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
(SKIP_PROLOGUE): No longer a no-op.
(SAVED_PC_AFTER_CALL): Now handles leaf procedures.
(*_REGNUM): Sort register numbers.
(REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
are now 10 byte extendeds, not 8 byte doubles.
(FRAME_CHAIN_VALID): Make this config-dependent, since it differs
for nindy versus vxworks targets. FIXME, this should possibly go
in the target vector.
(EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
frame_saved_regs and arg pointer with each frame.
(FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
(FRAME_ARGS_ADDRESS): Use cached result.
(FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
(FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
(PRINT_RAMDON_SIGNAL): Call print_fault.
(POP_FRAME): Now works.
* tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
(ADDITIONAL_OPTION_HANDLER): use target_load, not
target_add_file.
* tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
* valarith.c (value_subscripted_rvalue): Avoid handling
floats and doubles specially; it gave alignment errors. Lint.
* valops.c (value_of_variable, value_of_this): Error if unknown
value.
* valprint.c (print_floating): Bcopy rather than pointer-deref,
to avoid alignment problems.
(value_print): Handle unknown value address.
(cplus_val_print): Two args are ignored; remove them. Change caller.
(val_print): Use unpack_long rather than pointer-deref.
* values.c: Lint.
(unpack_long, unpack_double): Use bcopy rather than pointer-deref
to avoid alignment problems.
(value_being_returned): Error if return value unknown.
(set_return_value): Add bogosity warning, FIXME. *
* TODO: A woman's work is never done.
* Makefile.dist: Distribute REMOTE_OBS into tconfig files.
Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
Add ieee-float.o to OBS.
* tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
* tconfig/i960: FIXME. Half-merge, produce warning if config'd.
Changes to generalize the VxWorks RPC protocol slightly, to handle
i960 as well as 68000.
* vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
* vx-share/reg.h: Produce i960 regs #ifdef I80960
* vx-share/xdr_ptrace.c: Skip FPA registers if 960.
* vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
* vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
* vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
for i960. Change xdr_vectors to xdr_opaques for 68k registers,
so they will move in target byte order rather than network
byte order (happens to be the same).
Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
* tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
* am29k-pinsn.c,
Add contribution lines to various files, showing where they
came from.
* breakpoint.c (break_insn, check_break_insn_size,
read_memory_nobpt): Remove to mem-break.c.
* xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
HOST_BYTE_ORDER.
* tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
entry has bad register number. This change is not
tested in this release, FIXME.
* frame.h: Eliminate Frame_unknown in favor of a simple zero.
tm-vax.h: Ditto.
* value.h: Force value's contents field to be aligned to hold
at least a double or a long long (if supported). This avoids
doing bcopy's in and out of the contents field.
(step_1): Avoid coredump under obscure circumstances when we
have no frame.
* symtab.h (misc_info): Add field to misc function vector for
any kind of cached information the target code desires. AMD
29000 uses this to avoid repeating examine_function_prologue's.
* coffread.c: Lint. Remove static symfile, read_section_header.
core.c (have_core_file_p): Lint: remove.
expprint.c (print_subexp): Lint.
infptrace.c, valops.c, valprint.c: lint.
Roll in changes from vxgdb-5.0.1:
* symtab.h: Comment byte order of each address class. Add
LOC_LOCAL_ARG for frame-relative args (960).
expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
symtab.c, symmisc.c: ditto.
* infrun.c (init_wait_for_inferior): Clear stop_signal.
* remote.c (remote_resume): Error if resume with a signal.
* symfile.c (prim_record_misc_function): Clear misc_info.
(fill_in_vptr_fieldno): Check stub type of arg.
* valops.c (value_cast): Avoid looking up names of types whose
name we don't know, to prevent coredump. Sun CC produces typedef
rtx and the name of *rtx is zero...
Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
Roll in changes from final AMD 29000 port (Tiemann).
tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
for ../include/a.out.encap.h. This might not work now that BFD
is separately compiled. Instead, BFD support for encap will have
to translate machine type 29k into the right COFF_MAGIC.
* infcmd.c: Remove references to inferior_pid that aren't used
in actual ptrace calls; use target_has_execution, etc.
(have_inferior_p): Remove function.
(program_info): Print target info rather than "process number";
avoid gratuitous messages unless from_tty.
(run_stack_dummy, finish_command): Set proceed_to_finish.
infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
main.c: Lint. Lose have_inferior_p().
inferior.h (have_inferior_p): Remove, lint.
(proceed_to_finish): Add flag to ask that all regs be saved
by normal_stop, for the few commands that need it, speeding up
serial I/O. Add comments to stop_registers.
* remote-eb.c: Remove newline from breakpoint message we grep
for. Never time out when running the user program.
Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
Roll in changes from vxgdb-5.0.1:
* dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
symbol in its raw form, we are processing an unlinked ".o" file.
See if the target environment has assigned it an address, using
target_lookup_symbol (VxWorks does), and enter it into the symtab
that way.
* tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
68k versions for a simpler version that assumes zero FP at bottom.
Fixes bug of truncated stack reports.
* target.h (target_lookup_symbol): Define this routine's args
and result, finally.
* target.c (nosymbol): Default routine for target_lookup_symbol.
(target_default): Default lookup_symbol and call_function too.
(files_info): Only print has_all_memory warning if a non-dummy
target follows.
* remote-vx.c (vx_read_register, vx_convert_to_virtual,
vx_convert_from_virtual): If target does not have floating point,
zero register "values", and avoid doing cross-net conversions.
(vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
(vx_open): Rearrange code that attaches to target and reads
symbols for all loaded modules, to work if some of the modules
are not accessible. Add symbol_stub() and add_symbol_stub()
as callbacks from catch_errors(). Allow connect attempt to be
interrupted painlessly with ^C (FIXME, there are still some bugs
if the interrupt happens during symbol reading.). Print
final message with puts_filtered, since symbol messages are
now filtered too.
Misc cleanup:
* main.c (catch_errors): Only print errstring if non-null.
(command_loop): Avoid an ioctl per command to test ISATTY.
* remote-vx.c (net_load): make static; avoid sophomoric msg.
(vx_xfer_memory): Return correct result!
(vx_files_info): Indicate whether target has float or not.
(vx_lookup_symbol): Complain, not error, if target gone.
(vx_open): Print "Connected" msg before disabling immediate-quit.
[FIXME: lookup_symbol and vx_open changes need testing.]
target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
contributor lines and update copyrights to 1991.
Changes from an attempted H-PUX host port:
* infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
defines PT_ATTACH and PT_DETACH but not PT_KILL.
* remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
* remote-vx.c: include <sys/time.h> for HPUX.
* hp300hpux-xdep.c (fetch_core_registers): Rewrite old
"core_file_command" routine to BFD regime. May not work yet.
Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
* xgdb.c: Replace X10 version with some VJ version.
(FIXME: Its copyright assignment is not on record.)
* xgdb.c: Update include files to X11R4 (Xaw crud).
(xgdb_display_source, create_text_widget): fix call to
get_filename_and_charpos. Rewack source window stuff for X11R4
(gleaned from include files, and "nm's" of binary libraries, since
I had no doc available).
(append_selection, append_selection_word): Disable with FIXME
since R4 changed interface here.
(create_buttons): Add back the old set of buttons.
(xgdb_create_window): Fix call to XtInitialize (&argc not argc).
* Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
Roll VERSION to 3.94 (not yet final though).
Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
* obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
obstack_int_grow, obstack_int_grow_fast): Eliminate
cast on left of assignment, which gives MIPS cc fits and is
not Standard C.
* sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
F_ALIAS. Use printf, not fprintf, when not passing a file
pointer...
(compare_opcodes): Check that identical instructions have
identical opcodes, complain otherwise.
* sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
was reported by Roland McGrath.
(unimp): Only match if exactly zero instruction. (Roland)
(branches and traps): Generate all variations of these
instructions with macros, based on a single call that defines
each condition name and its binary representation.
(set): Turn on alias bit, to avoid test in sparc-pinsn.c.
* valprint.c (val_print_fields): Take, and use, format parameter.
This means that "p/x struct" again prints the elements in the
desired format. Changed callers.
* stack.c (frame_info): Use filtered output, and indicate wrap
points. Remove kludgy formatting designed to avoid line wrap.
* utils.c (wrap_here): If the line is already full (because
we had printed a long indent or long wrapped string), do an
immediate newline-and-indent.
* m68k-pinsn.c (print_insn_arg): Bugfix from
ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
instruction is incorrectly disassembled as bkpt #8.
* dbxread.c (end_psymtab): Bugfix from Peter Schauer
<pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
breakpoint in a *.y file gdb will say Reading in symbols for *.y...
and then will dump core (sometimes). I traced it back to an
uninitialized symfile_name in psymtab_to_symtab.
(const_vol_complaint): Add quotes to message.
(define_symbol): Only believe line number if gcc_compiled.
Avoid allocating symbol if we will not return it.
Add target strata support so that newly established targets go
into their right place in the target stack (e.g. a new exec file
doesn't wipe out the ability to access the running process).
* target.h, core.c, exec.c, inftarg.c, remote-eb.c,
remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
and initialize it properly in all the targets.
* target.h: Document strata. Change return type of push_target.
* target.c (nomemory): new function for dummy memory access.
(tcomplain): Rename complain, now also used in symfile.c.
(push_target): Push targets within strata. New return value shows
whether new target is on top of stack or not. Always keep dummy
target on stack.
(target_files_info): Ignore dummy target.
* core.c (core_open): Warn user, and skip accessing file, if the
core target is not the topmost target in the stack.
* remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
already handled.
* remote-vx.c: Remove vx_prepare_to_store from vxworks memory
target_ops, it doesn't belong there since we have no regs there.
Change name of target from machine => memory to clarify.
Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
* Freeze version 3.93 for release.
* Makefile.dist: Handle vx-share and nindy-share subdirs
properly when building gdb.tar.Z.
* symtab.c: lint; add no_symtab_msg to consolidate the messages
printed in various places, so I could change just one copy.
* dbxread.c, coffread.c: Change references to bfd->iostream
to cast to FILE *, now that BFD avoids needing types defined
in other header files.
Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
* command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
(actually gcc -Wall).
* dbxread.c: Remove first_global_sym, last_global_sym, since
they are never referenced.
* defs.h (baud_rate): Declare.
main.c: Define it, and add the -b option to set it.
* gdb-int.texinfo: Add text on how to define a new host or target
architecture, prompted by Per Bothner's questions about MIPS
support.
* gdb.texinfo: Document "complaints". Change doc of -q since
gdb no longer prints the copyright and blurb if you specify a file
name to be debugged (just like Emacs). Add doc for Nindy-specific
command line flags for specifying target serial port and such.
Update copyright to 1991.
* gdbcore.h: Remove a large mass of now-useless crud, since BFD
has taken over for us the job of ripping up executable files. The
crud caused Per Bothner's port to not compile.
* infrun.c (normal_stop): Avoid printing "Program exited
normally" if we are in batch mode. This allows a GDB which
executes a program on a target system, to behave like a Unix
command (input from stdin, output to stdout, no extraneous
output).
* main.c (main): Allow additional machine-dependent command line
options to be specified with the ADDITIONAL_OPTIONS,
ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
processing to occur just before the main loop with
BEFORE_MAIN_LOOP_HOOK.
(main): If a "core file" argument is specified, and it is not a
core file, try it as a process ID to attach.
(symbol_completion_function): Attempt to cope with
"show screen-" TAB, not very successfully. This needs more work,
FIXME.
(batch_file): New function, returns whether we are reading
commands from an interactive tty on stdin, or from somewhere else.
Called by normal_stop since it doesn't get from_tty passed down
to it like many commands do.
* remote-nindy.c: Handle command line options for nindy
connection.
(nindy_before_main_loop): Prompt user for tty name if they
don't specify it before getting to the interactive command loop.
* tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
and -r command line options. Also add hook before main loop
to make it easy to specify a tty.
* TODO: More things to do, one done.
Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
* dbxread.c: Make complaint() calls pass pointer, not struct.
Add complaints about badly formatted C++ type information
(const/volatile indicator, and parse errors resulting in
error_type). Fix C++ virtual member fn comment.
(read_struct_type): Avoid bumping pointer if we got a parse
error; this prevents our walking beyond the end of a string.
Terminate loop on null char as well as semicolon.
(process_one_symbol): Fix the LBRAC fix so that it uses the
last previous SLINE, FUN, or SO record's PC address. C++ debug
symbols did not have SLINE records in a useful order compared
to the LBRAC records.
(define_symbol): Handle "catch" records.
* symtab.c (check_stub_type): Added new complain
`stub_noname_complain' and added a consistency check to
keep the debugger from crashing when finishing from an
exception frame. A real fix will be needed later.
Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
* infcmd.c (attach_command): Make global.
* Makefile.dist (REMOTE_OBS): Make these compile by default,
but make them easy to comment out. Perhaps later they should
be enabled by what CPU you configure for? FIXME.
(VERSION): Roll to 3.93.
(pinsn.o): Remove rule for obsolete file.
(dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
Run down a problem that manifested by printing the wrong function
name in stack traces of read_ofile_symtab. Turned out that the
problem was the SunOS 4.1.1 (and previous) C compiler outputs
the LBRAC symbol with an address in the *data* segment, which
blew our binary search through the blocks.
* dbxread.c: Use the complain() facility consistently to bitch
about problems in the symbol file we are reading.
(finish_block): Add code to check the nesting of the blocks;
complain and Procrust them to fit if wrong.
(make_blockvector): Check the order of the blocks, complain
[but don't cope] if wrong.
(process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
symbols to be sure their PC value is greater than the last SLINE
(line number) symbol we've seen, complaining and adopting the
SLINE PC value if wrong.
* symfile.h (struct complaint, complaint_root, complain,
clear_complaints): Add.
* symfile.c (complain, complaint_root, clear_complaints): Add
facility to deal with non-fatal complaints and to regularize their
suppression.
(symbol_file_add): Clear complaint counters to allow new complaints.
(initialize_symfile): Add 'set complaints' and 'show complaints'.
* dbxread.c (dbx_symfile_read): Remember the address and size
of the string table for the main symbol file, so we won't read it
more than once.
(dbx_psymtab_to_symtab): Fix the check for main symbol file,
to avoid reading the string table yet again. Lint.
(throughout): Improve filtered output, including word wrap.
(read_range_type): Improve Bothner's fix to handle other types too.
* utils.c: Improve line wrap implementation. Handle unlimited
width by making chars_per_line unsigned.
(puts_filtered): New, easy, function.
* defs.h (puts_filtered): add.
* mipsread.c (compare_symbols, sort_symtab): Remove these fns,
call the identical sort_symtab_syms() in symfile.c instead.
* expread.y: Suggest the `file' command rather than `symbol-file'.
* command.h (enum var_types): Add zinteger for seroable
unsigned integer.
* command.c (do_setshow_command): Handle var_zinteger. Restructure
nested if's into a switch.
* breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
we did not stop because of a breakpoint (it must have been for
some other reason, like a "stepi"), so don't print anything.
* symtab.c: Include <sys/types.h> all the time. Now that BFD
doesn't include <sys/types.h>, old SunOS's require it for
<sys/stat.h>.
Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
A test port of gdb-3.92.6 to the Sony NEWS.
* Makefile.dist
Don't normally link in remote- or vx stuff.
Some of it doesn't compile, and it wastes space for 99% of the users.
Remove reference to no-longer-used HAVE_VPRINTF.
Fixed BFD_DEP typo to BFD_DIR.
* dbxread.c
Fix cast in arg to bfd_h_getlong.
Make char *prefix be const.
Fix how certain range types are mapped into builtin unsigned int types.
* infrun.c
Remove 2 #includes. They cause errors (on Sony, at least),
and aren't needed (they wern't in earlier versions).
* printcmd.c
print_address_symbolic should never demangle labels
(since it prints *assembler-level* labels).
[This was superseded by the change to printcmd below.]
* utils.c
Add some "volatile" return types to avoid warnings.
If MISSING_VPRINTF add vprintf function and not just macro
(since vprintf is used in printcmd.c).
* valprint.c
Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
(The latter isn't grokked by some PCC-based compilers.)
[This change is in abeyance, we prefer to fix obstack_ptr_grow.]
Make chunk size of dont_print_obstack 32*4 instead of default 4096.
* nindy-share/coffstrip.c
Added some forward declarations (otherwise, gcc complains
about implicit extern redefined as static).
Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
Changes inspired by Per Bothner:
* printcmd.c (print_address_symbolic): Take additional parameter
specifying whether to demangle.
(print_address): Pass in asm_demangle to control demangling.
(print_address_demangle): New fn, takes explicit arg to control
demangling.
* utils.c: Add new vars demangle and asm_demangle, and let them
be set and shown.
(fputs_demangled): If !demangle, just print the argument.
(fprint_symbol): If !demangle, just print raw symbol.
* valprint.c (val_print): Call print_address_demangle rather than
print_address, to cause demangling to depend on the global
rather than assembler-level demangling setting.
* WHATS.NEW, gdb.texinfo: Document.
* main.c (show_command): Show all settings if no arg.
(initialize_main): Make "info set" the same as naked "show".
* command.c (cmd_show_list): Handle prefix commands in the
list, and print the name of the setting as well as its English
description and value.
Allow gdb functions to specify where a line should wrap if it
exceeds the size of a terminal line. Use it to make the output
prettier.
* utils.c (set_screen_width_command): New fn, mallocs a buffer
of the right size when screen width changes.
(set_screensize_command, screensize_info): Remove #if 0'd fns.
(wrap_here): New fn, indicates a point in the output where we
should wrap the line rather than just letting it overflow at a
random place.
(fputs_filtered): Implement wrapping.
(n_spaces): New fn, returns a pointer to N spaces.
(print_spaces_filtered): Use n_spaces.
* defs.h (n_spaces): Declare.
* stack.c (print_frame_info): Wrap with 4-space indent after
fn name and before filename and line number.
* printcmd.c (print_frame_args): Wrap with 4-space indent
before each argument name is printed.
* valprint.c (value_print): Wrap with no indentation before
each repetition.
(val_print_fields): Wrap with indentation relative to nesting
level before each field name.
(val_print): Wrap with nesting indentation before array elements.
* command.c (do_setshow_command): Avoid extra newlines,
wrap with 4-space indent around values printed, end with period.
* WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
* breakpoint.c (breakpoint_1): Implement addressprint for
"info breakpoints" display. Change file name and line number
format to " at file:nnn" rather than " (file line nnn)".
* gdb.texinfo: Document.
Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
Frozen for gdb-3.92.6 release.
README, WHATS.NEW: Update for 3.92.6 release.
tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
coffread.o from configs since it is now built by default.
tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
from configs since it is now built by default.
Makefile.dist: Update for release 3.92.6. Handle files that
have been moved to ../include, ../getopt, or ../bfd. Add
saber.suppress and tests directory. Add config.status to
the release (it will say "none").
coredep.c: Minor formatting fixes.
These changes were made in early December but only checked in now:
* nindy-share/Onindy.c, nindy-share/coffstrip.c,
nindy-share/nindy.c: lint
* nindy-share/nindy.c (ninStopWhy): Don't byteswap the
register values coming back from the target; we store values
in target byte order everywhere.
Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
* am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
* valprint.c (cplus_val_print, val_print_fields): New functions,
which print C++ objects. They conspire to avoid printing a
virtual base class more than once, following all the twists and
turns of C++ virtual base rules.
(val_print): Call the above rather than do it by hand.
* symfile.c (symbol_file_add): Only reset symfile_mtime for main
symbol file, not for added files like shared libs. This really
needs to be generalized to a timestamp per file.
* core.c (cleanup_core): Avoid coredump if no core file.
* config.gdb: Accept -host or -target in place of +host or
+target.
* coffread.c (find_linenos): Avoid desupported BFD interface
to line numbers. We still read them manually rather than using
BFD's "generic" features.
* gdbrc.tex, threecol.tex: Add GDB reference card and its
formatting code.
Makefile.dist: Add refcard to OTHERS list for creating tar files.
* Makefile.dist: Eliminate use of $< in explicit targets.
* readline/Makefile: Use $< rather than $*.c, which does not
include the VPATH in GNU Make.
* tconfig/i960-bout, tconfig/i960-coff: These are identical
copies of tconfig/i960, added for global configuration
compatability. All i960 versions can read both coff and b.out.
* tm-88k.h: Fix multiline macro that lacked \'s. Remove
COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
automaticaly.
* TODO: Think of more things to do.
Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
64-bit float conversion.
tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
equivalent to sun?os4 so global config works.
Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
* main.c: Only declare linesize once; declare pagesize not at
all, since it is never used.
(main): Clear newly allocated line before it is used.
