Run write_object_file after errors
This is to fix unitialised memory access when printing listings.
Many targets don't initialise parts of insn frags or data frags that
have fixups, relying on md_apply_fix to finalise the frag. Which is
fine normally, but means we need to run write_object_file after
errors, for listings. Otherwise MALLOC_PERTURB_=1 causes errors like:
x86_64-linux +FAIL: i386 mpx-inval-1
x86_64-linux +FAIL: i386 inval-equ-1
x86_64-linux +FAIL: i386 x86-64-mpx-inval-1
Running write_object_file after errors requires some tweaking to the
testsuite, since we then get extra errors reported from md_apply_fix.
gas/
* write.h (subsegs_finish): Delete declaration.
* write.c (subsegs_finish): Make static.
(write_object_file): Call subsegs_finish from here. Don't print
warning and error count here..
* as.c (main): ..do so here instead. Remove dead code for "no
object file generated". Split out count strings to better support
internationalisation. Don't call subsegs_finish. Tidy setting of
"keep_it". Run write_object_file even after errors.
(keep_it): Make static.
* config/obj-elf.c (elf_frob_symbol): Remove assert.
(elf_frob_file_before_adjust): Likewise.
gas/testsuite/
* gas/elf/bad-group.s: Use %function.
* gas/elf/bad-group.err: Expect correct line number. Allow
other errors.
* gas/elf/bad-size.err: Allow other errors. Match expected
error somewhat more rigorously.
* gas/i386/reloc32.l: Allow other errors.
* gas/i386/mpx-inval-1.l: Match applied relocs.
* gas/i386/x86-64-mpx-inval-1.l: Likewise, and nop padding.
* gas/i386/x86-64-mpx-inval-2.l: Match nop padding, and allow
other errors.
* gas/macros/dot.s: Use .balign.
* gas/macros/dot.l: Update alignment output.
* gas/symver/symver6.l: Allow other errors.
