963 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
964 case to set obj_format=elf. Must go before i386-*-sysv* case that
965 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
966 *-*-solaris case, and move to before *-sysv* case that wants to

991 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
993 * Extensive changes to permit symbols to contain any expression
994 type and to delay the computation of the expression until the
995 value is actually needed. This permits setting symbols to values
996 calculated based on object code size. Expressions were changed to
997 no longer be in a section, to stop the overloading of segment and
998 expression type that previously occurred.
1000 * as.c (big_section, pass1_section, diff_section, absent_section):
1002 (expr_section): Added (used for dummy symbols which hold

1086 (previous_section, previous_subsection): New vars.
1087 (obj_elf_section): Save current place in case DWARF code wants us
1088 to pop back to it. Handle unquoted section name as well as quoted
1089 section name. Don't crash on invalid strings.
1090 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1093 * config/obj-elf.h: Don't include struc-symbol.h.

1178 (omagic): Removed unused variable.
1180 * Preliminary support for m88k-coff.

1202 sy_resolved and sy_resolving single bit fields.
1203 * symbols.c (symbol_new): Don't initialize sy_forward field.

2320 avoid some redefinition complaints on some systems.
2321 (const, volatile): Don't need these conditionally defined if we

2323 (seg_name): Use CONST, not const.

2338 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2340 * Makefile.in: add dvi target; as-$(config).texinfo might live in
2341 srcdir, might be in objdir.

2360 * Makefile.in (targ-cpu.o): Depend on config.h.
2362 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2364 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2365 dropping a space immediately following an identifier.
2366 * expr.c, write.c: Rewrote assert expressions to not use multiple
2367 lines; I don't think that can be done portably.

2496 redundant, and triggers a VMS gcc compiler bug.
2498 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2499 current segment as an argument. (Ignored in all cases but VMS.)

2851 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2853 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2854 as symbols as well in the object file. Look for external functions
2855 that start with "__vt.", and turn them into variables, since the
2856 g++ compiler is incapable of doing this.
2857 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2859 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2860 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2861 have the name of the source file yet.
2862 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2864 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2866 * read.c (s_data): Always use "data_section", since it'll map to
2867 SEG_DATA or SEG_E1 if needed.
2868 (s_lcomm): Likewise with bss_section.
2869 (s_fill): Use memset, not bzero.
2871 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2893 (big_section, reg_section, pass1_section, diff_section,
2894 absent_section, text_section, data_section, bss_section): If
2895 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2896 mapping to segT enum values.
2897 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2898 if these are used or defined, if BFD_ASSEMBLER.
2899 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2900 subseg_new split into two functions.
2901 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2903 * as.h (volatile): Don't define if already defined.
2904 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2906 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2907 declare with format attribute for -Wformat checking.
2909 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2911 * app.c, config/tc-*.c: Don't include read.h, since it is already
2914 * These are based on patches from Minh Tran-le
2915 <mtranle@paris.intellicorp.com>.
2916 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2917 obj_format coffbfd and gas_target i386coff for target.
2918 (i[34]86-*-isc*): New host (uses sysv).
2919 * config/i386aix.mt: Removed (no longer used).
2920 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2922 (LDFLAGS): Added, defined as -shlib.
2923 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2924 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2925 (DOT_LABEL_PREFIX): Define.
2926 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2927 name rather than L0\001.
2928 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2930 * symbols.c, symbols.h (local_bss_counter): Removed.

2939 (size_section): Restored sanity check.
2940 (do_relocs_for): Base section address on s_paddr rather than
2941 computing it. Adjust a29k R_IHIHALF special case to account for
2942 section paddr (used to require paddr to be zero). If there are no
2943 reclos, set s_relptr to 0. Set relocation size in object_headers.
2944 (fill_section): Always set s_vaddr here, removing
2945 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2946 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2947 Set STYP_INFO for .comment.

2951 H_{SET,GET}_* macros.
2952 (do_linenos_for): Set lineno size in object_headers.
2953 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2954 set s_vaddr here. If string_byte_count remains 4, set it back to
2955 0, and only write strings out if there are some. Call
2956 fill_section before do_relocs_for and do_linenos_for.
2957 (obj_coff_section): Handle optional quoted second argument giving
2958 section characteristics.
2959 (obj_coff_bss): Added to handle .bss.
2960 (obj_coff_ident): Added to handle .ident (puts string in .comment

2966 adjustment (already happened only for common symbols, but this is
2968 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2980 (do_scrub_next_char): For \", return " not '.
2981 (symbol_chars): Now const.
2983 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2984 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2986 * config/obj-coff.h: Don't use #elif.
2988 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2989 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3018 never set segment address for SEG_E2 (.bss) and don't write out
3019 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3020 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3021 definitions, and don't merge tags with non-tags. Check for .bf
3022 rather than just checking whether the second character is b and
3023 the third character is f.
3024 (obj_coff_val): gcc can generate values which we don't handle
3025 correctly; discard information for now, since it only affects the
3026 debugging information.

3028 (yank_symbols): Don't merge labels.
3029 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3327 sections starting from zero, rather than making them consecutive.
3328 This makes subsequent reloc calculations easier, esp if the object
3329 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3330 allocate lcomm in .data rather than in .bss. It seems that some
3331 tools can't cope with a non-zero sized bss before linkage.
3333 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3335 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3336 throughout. That enum no longer means what we thought it meant.

3357 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3359 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3360 .word is < -32768 or > 32767. The -J flag causes the error to be
3361 ignored. This is to catch over-sized switches generated by gcc on
3362 systems which don't support the broken .word hack.
3363 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3364 write.c (fixup_segment): check for signed .word overflow if
3365 WARN_SIGNED_OVERFLOW_WORD.

3394 From Steve Chamberlain:
3395 Makefile.in: Handle m68*-*-coff*.
3396 read.c, read.h: add mult argument to s_space
3398 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3399 Motorola and MIT syntax; gas can now assemble either type of
3401 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3411 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3414 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3416 * Makefile.in (LIBS): Include opcode library.

3443 * config/tc-m68k.c (init_table): Now const. Always include 68851
3444 data, so that "bc" is available to 68040 cache instructions.
3445 Added "tt0", "tt1", and 68ec030 variants.
3446 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3447 (enum _register): Added TT0, TT1.
3448 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3449 line number correctly in "internal error" messages. Don't print
3450 architecture-mismatch message for operand errors.
3452 From Colin Smith (colin@wrs.com):
3453 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

3475 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3476 has already been formatted (but may still contain %-characters).
3479 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3481 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3482 written with indirection on the last two operands, which can be
3483 either data or address registers. Added a new operand type 'r'
3484 which accepts either register type. Added '(' to notend stuff in
3485 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3826 * expr.c: If an expression is single comma, then return with
3827 SEG_ABSENT rather than an error - since the sparc front end does
3828 really strange things with things like fbge,a
3830 * as.h: include bfd.h if using many sections
3831 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3832 local labels didn't work.
3833 * listing.c (list_symbol_table): don't core dump when there's no
3835 * write.c, write.h: call fix_new with the right number of args on
3837 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3840 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3842 * app.c: MRI compatibility - allow single quote to start a string.
3843 * as.c: fix typo recently introduced.
3844 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3845 * expr.c: Much rewriting, to accomodate MRI syntax for
3846 expressions. Also easier to read now.
3847 * listing.c: Put back defuns
3848 * read.c: modified to accept MRI syntax, put back listing pseudo
3849 ops so that an assembler built with NO_LISTING ignores list ops
3851 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3852 machine is a SPARC or a 29K.
3853 * config/obj-aout.c: added s_sect pseudo op
3854 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3855 fill in the timestamp.
3856 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3857 anymore, define all the relocs which the tc-<x> bit will use so we
3858 can translate from them to the coff types.
3859 * config/tc-a29k.c: reloc_type isn't ane enum any more
3860 * config/tc-m68k.c: Added NO_RELOC definition.
3862 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3864 * Makefile.in: put header files before C source for TAGS; remove
3865 references to non-existent syscalls.h.
3867 * read.c, write.c subsegs.c: back out the .bss changes.
3869 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3871 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3875 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3877 * symbols.c (local_label_name): symbols now start with ^A.
3879 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3880 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3881 generate these sections. .align: will use NOP_OPCODE or 0
3882 for padding. This is just for being nice to the
3885 * expr.c (operand): changed to generate local label "\001L0"
3886 starting with a ^A so that it is recognized as a local label.
3888 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3890 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3891 i/o opcodes - inb, inw, outb and outw. string manipulation with
3892 att syntax - scmp, slod, smov, ssca, ssto.
3894 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3895 to just after .file .
3897 In obj_crawl_symbol_chain() where it tries to put the external
3898 symbols apart, with the condition:
3899 (!S_IS_DEFINED(symbolP) &&
3900 !S_IS_DEBUG(symbolP) &&
3901 !SF_GET_STATICS(symbolP))
3902 it was moving too many symbols out. So I switch it back to the
3904 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3906 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3907 so that we don't use the F_RELFLG which make the linker complain
3908 that somebody has stripped the relocation info.
3910 Also, the AIX ld program require that the relocation table
3911 is sorted by r_vaddr like the standard ATT assembler does.
3913 [he also changed the sizeof(struct ...)'s into the coff
3914 style FOOSZ macros. I'm not sure this is right, but I can't
3915 remember why. xoxorich.]
3917 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3919 * Makefile.in, configure.in, doc: use the doc. Build it, install
3922 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3924 * read.c: white space and comments only.
3926 * configure.in: use the new atof-ns32.c for ns32k.
3928 * write.c: comment change only.
3930 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3931 aren't yet integrated.
3933 * tc-i860.[hc]: blew off the dust. Something must still be done
3934 about conflicting relocation types.
3936 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3939 * tc-i960.c, tc-sparc.c: white space and comments only.
3941 * tc-a29k.h: delete duplicate macro definition.
3943 * new file atof-ns32k.c copied from hack's last unreleased gas.
3945 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3947 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3950 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3951 ChangeLog's prior to this are sketchy at best. I have logs.
3952 They just aren't ChangeLogs.
