The highest priority item is not on this list: Fix bugs in the
|
|||
|
|
existing testsuite, fix the GDB/compiler/shell/etc bugs which it
|
|||
|
|
detects (particularly when they are hard to XFAIL), make it run
|
|||
|
|
reliably without unexpected failures on the "standard" machines, etc.
|
|||
|
|
This list exists largely as "tests we can add when we are ready to
|
|||
|
|
risk destabilizing it again".
|
|||
|
|
|
|||
|
|
There are some tests which are only run on some platforms because they
|
|||
|
|
have not been tested on more platforms. Enable them and fix any
|
|||
|
|
problems. A partial list: recurse.exp, watchpoint.exp
|
|||
|
|
(test_watchpoint_triggered_in_syscall, test_complex_watchpoint).
|
|||
|
|
|
|||
|
|
Test printing of structures passed by value, for the 7th, 8th, and 9th
|
|||
|
|
arguments (PR 1714). Test printing structure arguments of
|
|||
|
|
2,4,6,8,12,16,and 20 bytes. Same for structure return of all those
|
|||
|
|
sizes ("return", "finish", and call function).
|
|||
|
|
|
|||
|
|
Get crossload tests to use --enable-targets and reenable them.
|
|||
|
|
|
|||
|
|
corefile.exp:
|
|||
|
|
Test ability to run program when there is a core target, then go
|
|||
|
|
back to the core file when the program exits.
|
|||
|
|
|
|||
|
|
Test handling of floating point variables
|
|||
|
|
1. float, double, or long double
|
|||
|
|
2. in register or saved register or memory. Also the case where a
|
|||
|
|
double is in two float registers and only one of them is saved.
|
|||
|
|
3. print them or set them
|
|||
|
|
4. (Alpha) integer (32 or 64 bit) in floating point register.
|
|||
|
|
|
|||
|
|
Print registers--"p $r5", "p sizeof ($r5)". Test that they print
|
|||
|
|
appropriately (integer registers in decimal, registers which always
|
|||
|
|
contain addresses (pc, probably sp and fp, maybe others) in hex,
|
|||
|
|
floating point).
|
|||
|
|
|
|||
|
|
Test completer. Test that it completes a variety of things correctly
|
|||
|
|
(see the list of test cases in main.c in the gdb source). Test TAB,
|
|||
|
|
M-?, and the "complete" command.
|
|||
|
|
|
|||
|
|
Test "info line" with all kinds of linespecs. Test that the last line
|
|||
|
|
of the file works right.
|
|||
|
|
|
|||
|
|
weird.exp--test that unrecognized cross-reference types or
|
|||
|
|
unrecognized visibility or virtual characters get skipped properly
|
|||
|
|
(see stabs.texinfo).
|
|||
|
|
|
|||
|
|
Test C++ nested types (especially if PR 1954 is fixed; even if not
|
|||
|
|
*some* things already should work even in the presence of nested
|
|||
|
|
types). Test classes nested more than 9 levels deep (g++ mangles
|
|||
|
|
these differently) (both a demangle test and some tests which also
|
|||
|
|
test the compiler). Test calling a method of a class nested more than
|
|||
|
|
9 levels (for gdb_mangle_name and demangling).
|
|||
|
|
|
|||
|
|
Test static member functions (C++). Test that "ptype" shows them
|
|||
|
|
correctly, both before and after they have been converted from stub
|
|||
|
|
methods. Test that we can call them.
|
|||
|
|
|
|||
|
|
Test printing complicated types, including functions, pointers to
|
|||
|
|
arrays of pointers of functions, functions which return pointers to
|
|||
|
|
functions, etc.
|
|||
|
|
|
|||
|
|
printcmd.exp--test printing enum values. Test printing an enum
|
|||
|
|
variable whose value is out of range. Test "p (int)enum_var", "p/x
|
|||
|
|
enum_var". Test that in something like "enum {FOO, LAST_THING=FOO}"
|
|||
|
|
we print FOO, not LAST_THING.
|
|||
|
|
|
|||
|
|
Test GDB expressions--test all operators (and overloaded operators for
|
|||
|
|
C++). Test integer constants which are signed or unsigned int, long,
|
|||
|
|
or long long. Test detection of overflow of an integer constant.
|
|||
|
|
Here are a few integer constants to test (test they get the right
|
|||
|
|
types): 5, 5LL, 5LuL, 5L6u (invalid), 5LU. Maybe things like
|
|||
|
|
0x12345678, 0x87654321, etc., but their types depend on sizes of int,
|
|||
|
|
long, etc.
|
|||
|
|
|
|||
|
|
Test that printing const-qualified versions of various types works.
|
|||
|
|
In particular, on the sparc and probably other machines, "double" is
|
|||
|
|
handled differently from most types because it requires more alignment
|
|||
|
|
and thus goes in a different section (there is a gcc 2.4.5 bug with
|
|||
|
|
"const double" on sparc).
|
|||
|
|
|
|||
|
|
Test that GDB's "source" command works and that things work if stdin
|
|||
|
|
is redirected (to a file or a pipe). Test user defined command. Run
|
|||
|
|
an inferior each of these ways (to test that inflow.c works). Test
|
|||
|
|
that GDB works if the last line of stdin or a source'd file lacks a
|
|||
|
|
newline.
|
|||
|
|
|
|||
|
|
Test that unmatched single quotes produce error messages, both in
|
|||
|
|
expressions and linespecs.
|
|||
|
|
|
|||
|
|
Test "cd". "foo/bar/.." should get simplified to "foo". "/../.."
|
|||
|
|
should not get simplified (for Mach). "/.." should not get simplified
|
|||
|
|
(for other networked OSes; POSIX.1 section B.2.3.7). All these
|
|||
|
|
examples should continue to work with trailing slashes.
|
|||
|
|
|
|||
|
|
Test scoping; here is a start
|
|||
|
|
1 int i=2;
|
|||
|
|
2 int j=3;
|
|||
|
|
3 main()
|
|||
|
|
4 {
|
|||
|
|
5 int i;
|
|||
|
|
6 for (i=600; i>0; i--)
|
|||
|
|
7 print_line(i);
|
|||
|
|
8 }
|
|||
|
|
9
|
|||
|
|
10 print_line(i)
|
|||
|
|
11 int i;
|
|||
|
|
12 {
|
|||
|
|
13 h();
|
|||
|
|
14 printf("%d\n",i);
|
|||
|
|
15 }
|
|||
|
|
16
|
|||
|
|
17 h()
|
|||
|
|
18 {
|
|||
|
|
19 printf("In h...");
|
|||
|
|
20 }
|
|||
|
|
Set a breakpoint in h, and print i, print_line::i, and main::i. Set a
|
|||
|
|
breakpoint in main (or don't run the program), and test that
|
|||
|
|
print_line::i is an error. But if i were static, "p main::i" should
|
|||
|
|
work even if the program is not being run.
|
|||
|
|
|
|||
|
|
Write a test for the reentracy bug with rs6000_struct_return_address
|
|||
|
|
in rs6000-tdep.c.
|
|||
|
|
|
|||
|
|
Test "return" from dummy frames. Test "return" from non-innermost
|
|||
|
|
frame. Test that "return" from a non-innermost frame restores
|
|||
|
|
registers which are saved not in that frame but in a frame more inner
|
|||
|
|
(I believe this currently works on few if any architectures).
|
|||
|
|
|
|||
|
|
FORTRAN common blocks (a.out and xcoff--weird.exp has the start of
|
|||
|
|
one but it is not quite right as of 19 Nov 1993).
|
|||
|
|
|
|||
|
|
Test that "x" command sets $_ and $__. Test $_ in general.
|
|||
|
|
|
|||
|
|
Test that "p/a" works when given addresses in text, data, and bss
|
|||
|
|
segments. Test that it works if program is compiled with or without
|
|||
|
|
-g. Test that it works if preceding symbol is static or if it is
|
|||
|
|
extern.
|
|||
|
|
|
|||
|
|
Given `char abc[] = "abc\0def";' test "x/s abc" followed by "x/s"
|
|||
|
|
(should display "abc" followed by "def"). Test this works with no
|
|||
|
|
error message even if this is the last thing in the section (tests
|
|||
|
|
that val_print_string ignores an error if the error occurs after the
|
|||
|
|
'\0').
|
|||
|
|
|
|||
|
|
Test ability to process NMAGIC a.out files.
|
|||
|
|
|
|||
|
|
Test shared libraries: "next" over printf, "step" into a function in
|
|||
|
|
a shared library which has line number info, breakpoint in a function
|
|||
|
|
in a shared library (either before or after the program is run and the
|
|||
|
|
shared libraries are loaded--also maybe write a test where the PLT
|
|||
|
|
will be in an unloaded state even though the shared library is loaded).
|
|||
|
|
|
|||
|
|
If there are two breakpoints in the same place, and exactly one of
|
|||
|
|
them has its condition true, test that the correct breakpoint gets
|
|||
|
|
printed.
|
|||
|
|
|
|||
|
|
Test "jump" including jump to a breakpoint (the latter will need an
|
|||
|
|
xfail for UDI and probably VxWorks (PR 1786 for vxworks; PR 2416
|
|||
|
|
contains some info for 29k).
|
|||
|
|
|
|||
|
|
Set a watchpoint on a local variable (to be interesting, make a few
|
|||
|
|
calls, to be more interesting, make a recursive call). Test that it
|
|||
|
|
gets disabled when leaving that scope.
|
|||
|
|
|
|||
|
|
Test calling a function, hitting a breakpoint in the called function,
|
|||
|
|
calling another function, and hitting a breakpoint. Test backtrace
|
|||
|
|
works in the presence of multiple dummy frames. Test that "continue"
|
|||
|
|
will get you out of the inner called function, and "continue" again
|
|||
|
|
will get you back to where you were when you called the first one.
|
|||
|
|
|
|||
|
|
Test special longjmp handling in wait_for_inferior (need to figure out
|
|||
|
|
in detail what the proper behavior in each case is). Test longjmp to
|
|||
|
|
a place where there is a breakpoint (such that
|
|||
|
|
BPSTAT_WHAT_CLEAR_LONGJMP_RESUME_SINGLE happens). In general, test
|
|||
|
|
interactions between longjmp and watchpoints, breakpoints, stepping,
|
|||
|
|
call function, etc.
|
|||
|
|
|
|||
|
|
Test jumping right past a breakpoint (the case where wait_for_inferior
|
|||
|
|
passes not_a_breakpoint to bpstat_stop_status). Might already be
|
|||
|
|
tested by some of the sun3 tests. Probably want a .s test to avoid
|
|||
|
|
compiler dependencies.
|
|||
|
|
|
|||
|
|
Test more obscure wait_for_inferior cases, expanding on the tests in
|
|||
|
|
watchpoint.exp, signals.exp, etc.
|
|||
|
|
|
|||
|
|
Test stepping into functions which are one line long and functions
|
|||
|
|
which are on line 1 of the source file. (there is a class of bugs in
|
|||
|
|
which gdb doesn't find the line number information, and thus doesn't
|
|||
|
|
step into the function).
|
|||
|
|
|
|||
|
|
Test that prologue recognition, backtrace, printing locals, etc.,
|
|||
|
|
still work in the presence of large frames (the point being that at
|
|||
|
|
some point immediate fields in RISC instructions will overflow and
|
|||
|
|
prologues will need to look different. For sparc, the immediate field
|
|||
|
|
is 13 bits (signed), so I believe the threshold would be 4K bytes in a
|
|||
|
|
frame).
