This set of patches add support for aout emulation on the x86

Browse Source 
assembler.  ie. You will be able to do "as --em=i386aout" on an x86
linux-elf assembler to generate aout format object files, rather than
using a separate assembler.  The aout emulation is enabled by giving
"--enable-targets=i386-linuxaout" to configure.
Oh yeah, there's a couple of fixes too.  Error messages shouldn't be
passed to printf in the format arg just in case someone puts a `%' in
the message.

2000-01-27 Alan Modra <alan@spri.levels.unisa.edu.au>
* Makefile.am (MULTI_CFILES): Add config/e-i386aout.c
Add dependencies for e-i386aout.o. Fix 2 comment lines.
* Makefile.in: Same here.
Update copyright.
* configure.in: Set bfd_gas for i386-aout when primary target
is bfd. Handle i386aout emulation. Don't use te_file=multi, as
we may need the primary te_file. Remove incorrect comment.
* configure: Regenerate.
* config/e-i386aout.c: New file.
* as.c (USE_EMULATIONS): Move to before print_version_id.
(struct emulation): Add i386aout.
(show_usage): Split text strings. Reformat -a text. Add --em
help.
Update copyright.
* obj.h (struct format_ops): Add s_get_other and s_get_desc.
(aout_format_ops): New.
Update copyright.
* read.c (s_lcomm_internal): Rewrite OBJ_AOUT,OBJ_BOUT
preprocessor conditional and add aout USE_EMULATIONS tests.

format arg.
Update copyright.

Update copyright.
* symbols.c (colon): Rewrite "already defined" fatal message
code for aout with USE_EMULATIONS.
Update copyright.

fields of sentinel.
(obj_aout_frob_symbol): Expand S_GET_DESC, S_GET_TYPE,
S_GET_OTHER, S_SET_TYPE macros since we don't need obj-multi
forms here.
(obj_aout_type): Expand S_SET_OTHER here too.
(obj_read_begin_hook): Remove.
(aout_pop_insert): New.
(obj_aout_s_get_other): New.

printf as format arg.

OBJ_MAYBE_ECOFF.
(elf_s_get_other): Declare.

(md_section_align): Similarly here.
(i386_target_format): Conditionally compile when more than one
of OBJ_MAYBE_{ELF,COFF,AOUT} defined. Add aout case.
