954 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
955 case to set obj_format=elf. Must go before i386-*-sysv* case that
956 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
957 *-*-solaris case, and move to before *-sysv* case that wants to
958 set obj_format to coff.

966 * config/obj-aout.c: Include aout/aout64.h.
967 (obj_aout_frob_symbol): Set BSF_DEBUGGING for a constructor
968 symbol, so that BFD doesn't tamper with the type.
970 * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, look
971 up opcodes as pseudo-ops even if they don't start with '.'.

982 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
984 * Extensive changes to permit symbols to contain any expression
985 type and to delay the computation of the expression until the
986 value is actually needed. This permits setting symbols to values
987 calculated based on object code size. Expressions were changed to
988 no longer be in a section, to stop the overloading of segment and
989 expression type that previously occurred.
991 * as.c (big_section, pass1_section, diff_section, absent_section):
993 (expr_section): Added (used for dummy symbols which hold

1077 (previous_section, previous_subsection): New vars.
1078 (obj_elf_section): Save current place in case DWARF code wants us
1079 to pop back to it. Handle unquoted section name as well as quoted
1080 section name. Don't crash on invalid strings.
1081 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1084 * config/obj-elf.h: Don't include struc-symbol.h.

1169 (omagic): Removed unused variable.
1171 * Preliminary support for m88k-coff.

1193 sy_resolved and sy_resolving single bit fields.
1194 * symbols.c (symbol_new): Don't initialize sy_forward field.

2329 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2331 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2356 dropping a space immediately following an identifier.

2486 * read.c (s_ignore): Don't declare is_end_of_line. It's
2487 redundant, and triggers a VMS gcc compiler bug.
2489 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2490 current segment as an argument. (Ignored in all cases but VMS.)
2491 All callers and definitions changed.

2808 (operand): Treat zero byte as end-of-operand.
2810 * configure.in (per-target): Look for with_bfd_assembler option.
2811 For now, only accept "no", until the merge is done.
2813 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2814 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2815 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2816 * read.c: Finish conversion to S_* macros in the VMS only
2817 parts of the program. Add "const" modifier to hex_value.
2818 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2820 * expr.c: Add "const" modifier to hex_value.
2821 * symbols.c: Finish conversion to S_* macros in the VMS only
2822 parts of the program. Add "const" modifier to
2823 md_[long,short]_jump_size. Remove declaration of const_flag
2824 (which will be declared in obj-vms.h).
2825 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2826 Fix arguments to VMS_write_object_file.
2827 * config-gas.com: New file. Script for VMS systems to set up the
2828 configuration to build gas for VMS, and create config.status.

2844 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2845 as symbols as well in the object file. Look for external functions

2852 have the name of the source file yet.
2853 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2855 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2857 * read.c (s_data): Always use "data_section", since it'll map to
2858 SEG_DATA or SEG_E1 if needed.
2859 (s_lcomm): Likewise with bss_section.
2860 (s_fill): Use memset, not bzero.
2862 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2874 * Changes for BFD_ASSEMBLER:
2875 * obj.h (obj_crawl_symbol_chain): Declare only if not
2877 (obj_header_append, obj_pre_write_hook): Ditto.
2878 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
2879 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

2889 if these are used or defined, if BFD_ASSEMBLER.
2890 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

2898 declare with format attribute for -Wformat checking.
2900 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2902 * app.c, config/tc-*.c: Don't include read.h, since it is already
2905 * These are based on patches from Minh Tran-le
2906 <mtranle@paris.intellicorp.com>.
2907 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2908 obj_format coffbfd and gas_target i386coff for target.
2909 (i[34]86-*-isc*): New host (uses sysv).
2910 * config/i386aix.mt: Removed (no longer used).
2911 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2913 (LDFLAGS): Added, defined as -shlib.
2914 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2915 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2916 (DOT_LABEL_PREFIX): Define.
2917 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2918 name rather than L0\001.
2919 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2921 * symbols.c, symbols.h (local_bss_counter): Removed.
2922 * write.c (write_object_file): bss no longer uses

2930 (size_section): Restored sanity check.
2931 (do_relocs_for): Base section address on s_paddr rather than
2932 computing it. Adjust a29k R_IHIHALF special case to account for
2933 section paddr (used to require paddr to be zero). If there are no
2934 reclos, set s_relptr to 0. Set relocation size in object_headers.
2935 (fill_section): Always set s_vaddr here, removing
2936 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2937 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2938 Set STYP_INFO for .comment.

2943 (do_linenos_for): Set lineno size in object_headers.
2944 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2945 set s_vaddr here. If string_byte_count remains 4, set it back to
2946 0, and only write strings out if there are some. Call
2947 fill_section before do_relocs_for and do_linenos_for.
2948 (obj_coff_section): Handle optional quoted second argument giving
2949 section characteristics.
2950 (obj_coff_bss): Added to handle .bss.
2951 (obj_coff_ident): Added to handle .ident (puts string in .comment
2953 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2954 (fixup_mdeps): Change to segment. Call frag_wane after
2956 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2957 adjustment (already happened only for common symbols, but this is
2959 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2971 (do_scrub_next_char): For \", return " not '.
2972 (symbol_chars): Now const.
2974 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2975 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2977 * config/obj-coff.h: Don't use #elif.
2979 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2980 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3007 using ZERO_BASED_SEGMENTS.
3008 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3009 never set segment address for SEG_E2 (.bss) and don't write out
3010 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3011 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3012 definitions, and don't merge tags with non-tags. Check for .bf
3013 rather than just checking whether the second character is b and
3014 the third character is f.
3015 (obj_coff_val): gcc can generate values which we don't handle
3016 correctly; discard information for now, since it only affects the
3017 debugging information.

3019 (yank_symbols): Don't merge labels.
3020 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3165 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
3166 could be doing emulation.
3168 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3171 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3200 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3202 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3203 constant will not fit in an immediate field.
3204 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
3206 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

3239 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3241 * Support for i386-sysv.
3242 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

3246 (fill_section): Don't set STYP_NOLOAD for .bss section.
3247 (fixup_segment): 386 uses strange common symbol format.

3266 * tc-m68k.c (get_num): make it work for all segments, not just the
3269 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
3271 * configure.in: recognize i386-*-bsd emulation.

3277 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3279 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
3280 * tc-z8k.c: lots of bug fixes
3282 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3284 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3285 #elif, since it is not supported by old compilers.
3286 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3287 couple of expressions in tc-m68k.c.
3289 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3291 * read.c (cons): If NO_RELOC is defined, use it.
3293 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3295 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3297 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3298 local labels to start with a .) and set REGISTER_PREFIX to %.
3299 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3301 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
3303 * messages.c: Comment changes.
3305 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

3315 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3317 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3318 sections starting from zero, rather than making them consecutive.
3319 This makes subsequent reloc calculations easier, esp if the object
3320 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3321 allocate lcomm in .data rather than in .bss. It seems that some
3322 tools can't cope with a non-zero sized bss before linkage.
3324 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3326 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3327 throughout. That enum no longer means what we thought it meant.

3350 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3351 .word is < -32768 or > 32767. The -J flag causes the error to be
3352 ignored. This is to catch over-sized switches generated by gcc on
3353 systems which don't support the broken .word hack.
3354 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3355 write.c (fixup_segment): check for signed .word overflow if
3356 WARN_SIGNED_OVERFLOW_WORD.

3385 From Steve Chamberlain:
3386 Makefile.in: Handle m68*-*-coff*.
3387 read.c, read.h: add mult argument to s_space
3389 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

3434 * config/tc-m68k.c (init_table): Now const. Always include 68851
3435 data, so that "bc" is available to 68040 cache instructions.
3436 Added "tt0", "tt1", and 68ec030 variants.
3437 (md_assemble): Complain if 68000 (only) and 68881 are specified.

3466 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3467 has already been formatted (but may still contain %-characters).
3470 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3472 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3473 written with indirection on the last two operands, which can be
3474 either data or address registers. Added a new operand type 'r'
3475 which accepts either register type. Added '(' to notend stuff in
3476 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3831 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3833 * app.c: MRI compatibility - allow single quote to start a string.
3834 * as.c: fix typo recently introduced.
3835 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3836 * expr.c: Much rewriting, to accomodate MRI syntax for
3837 expressions. Also easier to read now.
3838 * listing.c: Put back defuns
3839 * read.c: modified to accept MRI syntax, put back listing pseudo
3840 ops so that an assembler built with NO_LISTING ignores list ops
3842 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3843 machine is a SPARC or a 29K.
3844 * config/obj-aout.c: added s_sect pseudo op
3845 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3846 fill in the timestamp.
3847 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3848 anymore, define all the relocs which the tc-<x> bit will use so we
3849 can translate from them to the coff types.
3850 * config/tc-a29k.c: reloc_type isn't ane enum any more
3851 * config/tc-m68k.c: Added NO_RELOC definition.
3853 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3855 * Makefile.in: put header files before C source for TAGS; remove
3856 references to non-existent syscalls.h.
3858 * read.c, write.c subsegs.c: back out the .bss changes.
3860 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3862 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3866 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3868 * symbols.c (local_label_name): symbols now start with ^A.
3870 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3871 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3872 generate these sections. .align: will use NOP_OPCODE or 0
3873 for padding. This is just for being nice to the
3876 * expr.c (operand): changed to generate local label "\001L0"
3877 starting with a ^A so that it is recognized as a local label.
3879 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3881 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3882 i/o opcodes - inb, inw, outb and outw. string manipulation with
3883 att syntax - scmp, slod, smov, ssca, ssto.
3885 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3886 to just after .file .
3888 In obj_crawl_symbol_chain() where it tries to put the external
3889 symbols apart, with the condition:
3890 (!S_IS_DEFINED(symbolP) &&
3891 !S_IS_DEBUG(symbolP) &&
3892 !SF_GET_STATICS(symbolP))
3893 it was moving too many symbols out. So I switch it back to the
3895 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3897 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3898 so that we don't use the F_RELFLG which make the linker complain
3899 that somebody has stripped the relocation info.
3901 Also, the AIX ld program require that the relocation table
3902 is sorted by r_vaddr like the standard ATT assembler does.
3904 [he also changed the sizeof(struct ...)'s into the coff
3905 style FOOSZ macros. I'm not sure this is right, but I can't
3906 remember why. xoxorich.]
3908 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3910 * Makefile.in, configure.in, doc: use the doc. Build it, install
3913 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3915 * read.c: white space and comments only.
3917 * configure.in: use the new atof-ns32.c for ns32k.
3919 * write.c: comment change only.
3921 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3922 aren't yet integrated.
3924 * tc-i860.[hc]: blew off the dust. Something must still be done
3925 about conflicting relocation types.
3927 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3930 * tc-i960.c, tc-sparc.c: white space and comments only.
3932 * tc-a29k.h: delete duplicate macro definition.
3934 * new file atof-ns32k.c copied from hack's last unreleased gas.
3936 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3938 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3941 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3942 ChangeLog's prior to this are sketchy at best. I have logs.
3943 They just aren't ChangeLogs.
