One problem with --with-as/--with-ld is we are using nm/objdump/readelf
from the different version of binutils to test as/ld features. Sometimes, it
doesn't work too well. For example, we have
gcc_GAS_CHECK_FEATURE([working cfi advance], gcc_cv_as_cfi_advance_working,
,,
[ .text
.cfi_startproc
.cfi_adjust_cfa_offset 64
.skip 75040, 0
.cfi_adjust_cfa_offset 128
.cfi_endproc],
[[
if $gcc_cv_objdump -Wf conftest.o 2>/dev/null \
| grep 'DW_CFA_advance_loc[24]:[ ][ ]*75040[ ]'
>/dev/null; then
gcc_cv_as_cfi_advance_working=yes
fi
Our assembler supports CFI, but objdump may be too old to dump
DW_CFA_advance_loc
and this feature is mis-detected.
