Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com) * 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.

Changes from net 2.5.2 release branch: * configure.in: Put AC_DEFINE(sparcv9) on its own line, so that the shell variable settings associated with it are permanent. For CPUs requiring bfd_gas=yes, select it based on CPU only, not individual target names. Handle m68k-hp-hpux*, not just -hpux. * config/tc-z8k.c (tc_coff_symbol_emit_hook): Add dummy argument to match prototype in obj-coff.h. * configure.in: Skip tests for defining WANT_FOPEN_BIN and IBM_COMPILER_SUX. * acconfig.h: Deleted them. * configure, conf.in: Rebuild with autoconf 2.0. * config/go32.cfg, config/vms-conf.h: Updated. * config/tc-m68k.c (md_apply_fix_2, md_convert_frag_1): Always use IBM_COMPILER_SUX version of code, with comments indicating why. * listing.c (file_info): Use text mode when opening file for read. Use "r" directly, no macro. * input-file.c (input_file_open): Don't use FOPEN_RT, just use "r". * read.c (s_include): Ditto. * output-file.c (output_file_create): Try both "wb" and "w", don't bother with FOPEN_* macros. * as.h: Don't include fopen-*.h. * config/alpha-opcode.h: Make "ret" with no operands equivalent to "ret zero,(ra)", to match OSF1 and to be consistent with both one-operand forms. Patches from DJ Delorie: * as.h (alloca): undef alloca before defining it just in case * config/go32.cfg: new file for autoconf values * config/te-go32.h: new file * configure.bat: new for autoconf * config/tc-i386.c (md_assemble): Fix typo in GOTPC check; had = for ==. * configure.in: If target_frag doesn't exist, use /dev/null. * as.c (parse_args): For non-VMS systems, re-add `v' to std_shortopts. Add "verbose" to list of long options. * write.c (adjust_reloc_syms): When generating an absolute section symbol as a placeholder, don't mark it as used in a relocation entry, here. * Makefile.in (comparison): Compare using makefile code from gcc, stripped down to discard subdir stuff and adapted to give a non-zero exit status if either file differs.
