+
+ * These are based on patches from Minh Tran-le

+ * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use

+ (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.
