* app.c, config/tc-*.c: Don't include read.h, since it is already
included by as.h.
* These are based on patches from Minh Tran-le
<mtranle@paris.intellicorp.com>.
* configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
obj_format coffbfd and gas_target i386coff for target.
(i[34]86-*-isc*): New host (uses sysv).
* config/i386aix.mt: Removed (no longer used).
* config/mh-i386aix (RANLIB): Use true rather than /bin/true.
(MINUS_G): Removed.
(LDFLAGS): Added, defined as -shlib.
* config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
* config/te-sco386.h (LOCAL_LABEL): Don't define.
(DOT_LABEL_PREFIX): Define.
* expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
name rather than L0\001.
* read.c (s_lcomm): Make a frag in SEG_BSS rather than using
local_bss_counter.
* symbols.c, symbols.h (local_bss_counter): Removed.
* write.c (write_object_file): bss no longer uses
local_bss_counter. Pass correct data and bss size to
VMS_write_object_file.
* config/obj-vms.c (VMS_write_object_file): Accept bss size as
argument, rather than using local_bss_counter.
* config/tc-m88k.c (s_bss): Don't use local_bss_counter.
* config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
* config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
(size_section): Restored sanity check.
(do_relocs_for): Base section address on s_paddr rather than
computing it. Adjust a29k R_IHIHALF special case to account for
section paddr (used to require paddr to be zero). If there are no
reclos, set s_relptr to 0. Set relocation size in object_headers.
(fill_section): Always set s_vaddr here, removing
ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
Set STYP_INFO for .comment.
(coff_header_append): Use object headers and H_{SET,GET}_* macros.
Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
(crawl_symbols): Handle 8 character section name correctly. Use
H_{SET,GET}_* macros.
(do_linenos_for): Set lineno size in object_headers.
(write_object_file): Use H_{SET,GET}_* macros. Don't bother to
set s_vaddr here. If string_byte_count remains 4, set it back to
0, and only write strings out if there are some. Call
fill_section before do_relocs_for and do_linenos_for.
(obj_coff_section): Handle optional quoted second argument giving
section characteristics.
(obj_coff_bss): Added to handle .bss.
(obj_coff_ident): Added to handle .ident (puts string in .comment
section).
(obj_coff_lcomm): Put common symbols in .bss, not .data.
(fixup_mdeps): Change to segment. Call frag_wane after
md_convert_frag.
(fixup_segment): Explicitly check S_IS_COMMON before making 386
adjustment (already happened only for common symbols, but this is
clearer).
* config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
* config/tc-i386.c (s_bss): Don't use if I386COFF.
(md_pseudo_table): Ignore .optim and .noopt.
(tc_coff_sizemachdep): New function.
* config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
compatibility.
(LOCAL_LABEL): Removed definition.
(DOT_LABEL_PREFIX): Defined.
