1038 are also magic, and have special default flag settings.
1039 (obj_elf_frob_symbol): Since the return value from this function

1103 * Extensive changes to permit symbols to contain any expression
1104 type and to delay the computation of the expression until the
1105 value is actually needed. This permits setting symbols to values
1106 calculated based on object code size. Expressions were changed to
1107 no longer be in a section, to stop the overloading of segment and
1108 expression type that previously occurred.
1110 * as.c (big_section, pass1_section, diff_section, absent_section):
1112 (expr_section): Added (used for dummy symbols which hold

1196 (previous_section, previous_subsection): New vars.
1197 (obj_elf_section): Save current place in case DWARF code wants us
1198 to pop back to it. Handle unquoted section name as well as quoted
1199 section name. Don't crash on invalid strings.
1200 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

1312 sy_resolved and sy_resolving single bit fields.
1313 * symbols.c (symbol_new): Don't initialize sy_forward field.

2378 dependencies are read, not when they are used).
2380 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2381 a29k .bss section; the mondfe program doesn't like it.

2426 process relocs if there aren't any relocs to process. Avoids
2427 malloc/free bug on SCO too.

2430 avoid some redefinition complaints on some systems.
2431 (const, volatile): Don't need these conditionally defined if we
2432 use CONST and VOLATILE from ansidecl.h.
2433 (seg_name): Use CONST, not const.
2435 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2437 * config/tc-mips.c: Reindented to GNU standards.

2448 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2450 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2470 * Makefile.in (targ-cpu.o): Depend on config.h.
2472 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2474 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2475 dropping a space immediately following an identifier.
2476 * expr.c, write.c: Rewrote assert expressions to not use multiple
2477 lines; I don't think that can be done portably.
2478 * config/tc-mips.c (macro): Use $AT if target register is zero in
2479 load instruction, which it can be for a floating point load.
2481 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2502 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2504 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
2505 to be on a single line.

2553 prototypes for all static functions. Moved existing minimal
2554 debugging format support info #ifndef OBJ_ECOFF blocks.

2605 * read.c (s_ignore): Don't declare is_end_of_line. It's
2606 redundant, and triggers a VMS gcc compiler bug.
2608 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2609 current segment as an argument. (Ignored in all cases but VMS.)
2610 All callers and definitions changed.

2906 * config/tc-sparc.c (architecture_requested, warn_on_bump,
2907 md_relax_table): Use default zero initialization.
2908 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2909 latter, instead of selecting with preprocessor conditionals.
2911 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2913 * configure.in: recognise all sparclite variants
2915 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

2921 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2923 * expr.c (operand): If character other than comma or newline is a
2924 logical end-of-line character, use the newline case.
2925 From Eric Youngdale:
2926 (operand): Set X_add_number field for floating-point numbers.
2927 (operand): Treat zero byte as end-of-operand.
2929 * configure.in (per-target): Look for with_bfd_assembler option.
2930 For now, only accept "no", until the merge is done.
2932 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2933 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2934 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2935 * read.c: Finish conversion to S_* macros in the VMS only
2936 parts of the program. Add "const" modifier to hex_value.
2937 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2939 * expr.c: Add "const" modifier to hex_value.
2940 * symbols.c: Finish conversion to S_* macros in the VMS only
2941 parts of the program. Add "const" modifier to
2942 md_[long,short]_jump_size. Remove declaration of const_flag
2943 (which will be declared in obj-vms.h).
2944 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2945 Fix arguments to VMS_write_object_file.
2946 * config-gas.com: New file. Script for VMS systems to set up the
2947 configuration to build gas for VMS, and create config.status.
2948 * make-gas.com: Redone to work with new scheme.
2949 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2951 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2952 will swap bytes if needed on a big endian system. Use throughout
2954 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2955 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2956 types of malformed stabs. Change parsing algorithm so that we are
2957 more certain of having all of the information that we need on hand.
2958 * obj-vms.c (final_forward_reference): New function, used to help
2959 resolve the data types of as many struct elements as possible
2960 when some part of the struct is not fully defined by the compiler.

2963 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2964 as symbols as well in the object file. Look for external functions
2965 that start with "__vt.", and turn them into variables, since the
2966 g++ compiler is incapable of doing this.
2967 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2969 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2970 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2971 have the name of the source file yet.
2972 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2974 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2976 * read.c (s_data): Always use "data_section", since it'll map to
2977 SEG_DATA or SEG_E1 if needed.
2978 (s_lcomm): Likewise with bss_section.
2979 (s_fill): Use memset, not bzero.
2981 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3002 (section_alignment): Declare only if not BFD_ASSEMBLER.
3003 (big_section, reg_section, pass1_section, diff_section,
3004 absent_section, text_section, data_section, bss_section): If
3005 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3006 mapping to segT enum values.
3007 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3008 if these are used or defined, if BFD_ASSEMBLER.
3009 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3010 subseg_new split into two functions.
3011 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3013 * as.h (volatile): Don't define if already defined.
3014 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3016 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3017 declare with format attribute for -Wformat checking.
3019 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3021 * app.c, config/tc-*.c: Don't include read.h, since it is already
3024 * These are based on patches from Minh Tran-le
3025 <mtranle@paris.intellicorp.com>.
3026 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3027 obj_format coffbfd and gas_target i386coff for target.
3028 (i[34]86-*-isc*): New host (uses sysv).
3029 * config/i386aix.mt: Removed (no longer used).
3030 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3032 (LDFLAGS): Added, defined as -shlib.
3033 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3034 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3035 (DOT_LABEL_PREFIX): Define.
3036 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3037 name rather than L0\001.
3038 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3040 * symbols.c, symbols.h (local_bss_counter): Removed.
3041 * write.c (write_object_file): bss no longer uses

3049 (size_section): Restored sanity check.
3050 (do_relocs_for): Base section address on s_paddr rather than
3051 computing it. Adjust a29k R_IHIHALF special case to account for
3052 section paddr (used to require paddr to be zero). If there are no
3053 reclos, set s_relptr to 0. Set relocation size in object_headers.
3054 (fill_section): Always set s_vaddr here, removing
3055 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3056 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3057 Set STYP_INFO for .comment.

3061 H_{SET,GET}_* macros.
3062 (do_linenos_for): Set lineno size in object_headers.
3063 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3064 set s_vaddr here. If string_byte_count remains 4, set it back to
3065 0, and only write strings out if there are some. Call
3066 fill_section before do_relocs_for and do_linenos_for.
3067 (obj_coff_section): Handle optional quoted second argument giving
3068 section characteristics.
3069 (obj_coff_bss): Added to handle .bss.
3070 (obj_coff_ident): Added to handle .ident (puts string in .comment

3090 (do_scrub_next_char): For \", return " not '.
3091 (symbol_chars): Now const.
3093 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3094 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3096 * config/obj-coff.h: Don't use #elif.
3098 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3099 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3126 using ZERO_BASED_SEGMENTS.
3127 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3128 never set segment address for SEG_E2 (.bss) and don't write out
3129 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3130 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3131 definitions, and don't merge tags with non-tags. Check for .bf
3132 rather than just checking whether the second character is b and
3133 the third character is f.
3134 (obj_coff_val): gcc can generate values which we don't handle
3135 correctly; discard information for now, since it only affects the
3136 debugging information.
3137 (tag_find_or_name): Don't insert tags in the symbol table.
3138 (yank_symbols): Don't merge labels.
3139 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3342 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
3343 so widening works consistently.
3345 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
3347 * version.c: Put conditional "const" before version_string, not

3350 * app.c (do_scrub_next_char): Need double-\ before `000' to show
3351 printed rep of null character.
3353 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)

3358 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3360 * Support for i386-sysv.
3361 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3362 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3363 be used to set them all to zero as was done before.
3364 (fill_section): segment addresses now set in write_object_file.
3365 (fill_section): Don't set STYP_NOLOAD for .bss section.
3366 (fixup_segment): 386 uses strange common symbol format.

3403 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3404 #elif, since it is not supported by old compilers.
3405 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3406 couple of expressions in tc-m68k.c.
3408 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3410 * read.c (cons): If NO_RELOC is defined, use it.
3412 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3414 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3416 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3417 local labels to start with a .) and set REGISTER_PREFIX to %.
3418 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

3436 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3437 sections starting from zero, rather than making them consecutive.
3438 This makes subsequent reloc calculations easier, esp if the object
3439 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3440 allocate lcomm in .data rather than in .bss. It seems that some
3441 tools can't cope with a non-zero sized bss before linkage.
3443 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3445 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

3467 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3469 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3470 .word is < -32768 or > 32767. The -J flag causes the error to be
3471 ignored. This is to catch over-sized switches generated by gcc on
3472 systems which don't support the broken .word hack.
3473 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3474 write.c (fixup_segment): check for signed .word overflow if
3475 WARN_SIGNED_OVERFLOW_WORD.

3494 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3496 * input-scrub.c (input_scrub_push): call input_file_begin, not
3498 messages.c (as_perror): print ": " between the passed in error and
3499 the strerror, like perror does.

3504 From Steve Chamberlain:
3505 Makefile.in: Handle m68*-*-coff*.
3506 read.c, read.h: add mult argument to s_space
3508 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3509 Motorola and MIT syntax; gas can now assemble either type of

3521 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3524 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3526 * Makefile.in (LIBS): Include opcode library.

3551 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3553 * config/tc-m68k.c (init_table): Now const. Always include 68851
3554 data, so that "bc" is available to 68040 cache instructions.
3555 Added "tt0", "tt1", and 68ec030 variants.
3556 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3557 (enum _register): Added TT0, TT1.
3558 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3559 line number correctly in "internal error" messages. Don't print
3560 architecture-mismatch message for operand errors.

3585 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3586 has already been formatted (but may still contain %-characters).
3589 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3591 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3592 written with indirection on the last two operands, which can be
3593 either data or address registers. Added a new operand type 'r'
3594 which accepts either register type. Added '(' to notend stuff in
3595 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3701 * expr.c (floating_constant): Separate "=-" to avoid confusing
3702 ancient or broken compilers.
3704 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
3705 processor/opcode mismatch, so reword the error message.
3706 (md_assemble): If no CPU has been set (even if FPU/PMMU
3707 characteristics have been), default to 68020. Don't need extra
3708 quotes around error string.

3820 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3822 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
3823 calc the base of relocs correctly.
3824 * tc-a29k.c (parse_operand): allow expressions to be in any section.
3826 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
3828 * as.c, write.c: use -K rather than -k for the broken word warning
3831 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

3839 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3841 * write.c (write_object_file): For b.out format, round up section
3842 start addresses to match required alignment.
3844 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3846 * Makefile.in (install): Install into $(tooldir)/bin, since that's
3847 where gcc looks for it.
3849 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
3851 * Makefile.in: Changed some lines to be less confusing for some
3854 * input-file.c: Conditionalize on _IOFBF, not VMS.
3856 * read.c, write.c: Change a series of ifdef/elif to

3871 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3873 * flonum-const.c: renamed flonum-konst.c to stop dos name
3876 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
3878 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
3879 tc-m68k.h to te-sun3.h.
3881 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
3883 * configure.in: vxworks68 gets te-sun3.h.
3885 * expr.c: remove limitation that local_labels_dollar or
3886 local_labels_fb must be < 10.
3888 * symbols.c: remove local_labels_dollar, replace with a function
3889 interface for a sparse array. All users adjusted.
3891 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
3893 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3895 * doc/Makefile.in: commented out line for building as-all.texinfo.
3898 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
3900 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

3912 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
3914 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3917 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3919 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3921 * expr.c (operand): if can't work out what sort of operand it is,
3922 then look through FLT_CHARS for a hint.
3924 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3926 * Makefile.in, configure.in: removed traces of namesubdir,
3927 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3928 copyrights to '92, changed some from Cygnus to FSF.
3930 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3931 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3932 copyrights to '92, changed some from Cygnus to FSF.
3934 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3936 * expr.c: If an expression is single comma, then return with
3937 SEG_ABSENT rather than an error - since the sparc front end does
3938 really strange things with things like fbge,a
3940 * as.h: include bfd.h if using many sections
3941 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3942 local labels didn't work.
3943 * listing.c (list_symbol_table): don't core dump when there's no
3945 * write.c, write.h: call fix_new with the right number of args on
3947 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3950 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3952 * app.c: MRI compatibility - allow single quote to start a string.
3953 * as.c: fix typo recently introduced.
3954 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3955 * expr.c: Much rewriting, to accomodate MRI syntax for
3956 expressions. Also easier to read now.
3957 * listing.c: Put back defuns
3958 * read.c: modified to accept MRI syntax, put back listing pseudo
3959 ops so that an assembler built with NO_LISTING ignores list ops
3961 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3962 machine is a SPARC or a 29K.
3963 * config/obj-aout.c: added s_sect pseudo op
3964 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3965 fill in the timestamp.
3966 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3967 anymore, define all the relocs which the tc-<x> bit will use so we
3968 can translate from them to the coff types.
3969 * config/tc-a29k.c: reloc_type isn't ane enum any more
3970 * config/tc-m68k.c: Added NO_RELOC definition.
3972 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3974 * Makefile.in: put header files before C source for TAGS; remove
3975 references to non-existent syscalls.h.
3977 * read.c, write.c subsegs.c: back out the .bss changes.
3979 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3981 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3985 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3987 * symbols.c (local_label_name): symbols now start with ^A.
3989 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3990 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3991 generate these sections. .align: will use NOP_OPCODE or 0
3992 for padding. This is just for being nice to the
3995 * expr.c (operand): changed to generate local label "\001L0"
3996 starting with a ^A so that it is recognized as a local label.
3998 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4000 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4001 i/o opcodes - inb, inw, outb and outw. string manipulation with
4002 att syntax - scmp, slod, smov, ssca, ssto.
4004 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4005 to just after .file .
4007 In obj_crawl_symbol_chain() where it tries to put the external
4008 symbols apart, with the condition:
4009 (!S_IS_DEFINED(symbolP) &&
4010 !S_IS_DEBUG(symbolP) &&
4011 !SF_GET_STATICS(symbolP))
4012 it was moving too many symbols out. So I switch it back to the
4014 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4016 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4017 so that we don't use the F_RELFLG which make the linker complain
4018 that somebody has stripped the relocation info.
4020 Also, the AIX ld program require that the relocation table
4021 is sorted by r_vaddr like the standard ATT assembler does.
4023 [he also changed the sizeof(struct ...)'s into the coff
4024 style FOOSZ macros. I'm not sure this is right, but I can't
4025 remember why. xoxorich.]
4027 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4029 * Makefile.in, configure.in, doc: use the doc. Build it, install
4032 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4034 * read.c: white space and comments only.
4036 * configure.in: use the new atof-ns32.c for ns32k.
4038 * write.c: comment change only.
4040 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4041 aren't yet integrated.
4043 * tc-i860.[hc]: blew off the dust. Something must still be done
4044 about conflicting relocation types.
4046 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4049 * tc-i960.c, tc-sparc.c: white space and comments only.
4051 * tc-a29k.h: delete duplicate macro definition.
4053 * new file atof-ns32k.c copied from hack's last unreleased gas.
4055 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4057 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4060 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4061 ChangeLog's prior to this are sketchy at best. I have logs.
4062 They just aren't ChangeLogs.
