# normally etext.
|
|
# SEPARATE_GOTPLT - if set, .got.plt should be separate output section,

# Many sections come in three flavours. There is the 'real' section,
|
|
# like ".data". Then there are the per-procedure or per-variable
|
|
# sections, generated by -ffunction-sections and -fdata-sections in GCC,
|
|
# and useful for --gc-sections, which for a variable "foo" might be
|
|
# ".data.foo". Then there are the linkonce sections, for which the linker
|
|
# eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
|
|
# The exact correspondences are:
|
|
#
|
|
# Section Linkonce section
|
|
# .text .gnu.linkonce.t.foo
|
|
# .rodata .gnu.linkonce.r.foo
|
|
# .data .gnu.linkonce.d.foo
|
|
# .bss .gnu.linkonce.b.foo
|
|
# .sdata .gnu.linkonce.s.foo
|
|
# .sbss .gnu.linkonce.sb.foo
|
|
# .sdata2 .gnu.linkonce.s2.foo
|
|
# .sbss2 .gnu.linkonce.sb2.foo
|
|
# .debug_info .gnu.linkonce.wi.foo
|
|
# .tdata .gnu.linkonce.td.foo
|
|
# .tbss .gnu.linkonce.tb.foo
|
|
# .lrodata .gnu.linkonce.lr.foo
|
|
# .ldata .gnu.linkonce.l.foo
|
|
# .lbss .gnu.linkonce.lb.foo
|
|
#
|
|
# Each of these can also have corresponding .rel.* and .rela.* sections.
