699 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
701 * Extensive changes to permit symbols to contain any expression
702 type and to delay the computation of the expression until the
703 value is actually needed. This permits setting symbols to values
704 calculated based on object code size. Expressions were changed to

797 section name. Don't crash on invalid strings.
798 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
801 * config/obj-elf.h: Don't include struc-symbol.h.

858 (macro): Call mips_emit_delays before setting mips_noreorder.
859 Increment and decrement mips_noreorder rather than using

910 sy_resolved and sy_resolving single bit fields.
911 * symbols.c (symbol_new): Don't initialize sy_forward field.
912 (resolve_symbol_value): New function to adjust symbol value by
913 fragment address, using recursion to resolve forward symbols.

918 symbols, keeping the common case (the old behaviour) inline.
919 * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward

2028 avoid some redefinition complaints on some systems.
2029 (const, volatile): Don't need these conditionally defined if we
2030 use CONST and VOLATILE from ansidecl.h.
2031 (seg_name): Use CONST, not const.
2033 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2035 * config/tc-mips.c: Reindented to GNU standards.

2068 * Makefile.in (targ-cpu.o): Depend on config.h.
2070 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2072 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2073 dropping a space immediately following an identifier.
2074 * expr.c, write.c: Rewrote assert expressions to not use multiple
2075 lines; I don't think that can be done portably.
2076 * config/tc-mips.c (macro): Use $AT if target register is zero in
2077 load instruction, which it can be for a floating point load.
2079 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2100 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2102 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

2151 prototypes for all static functions. Moved existing minimal
2152 debugging format support info #ifndef OBJ_ECOFF blocks.

2201 * make-gas.com: Find obstack.obj if it's not in the current
2203 * read.c (s_ignore): Don't declare is_end_of_line. It's
2204 redundant, and triggers a VMS gcc compiler bug.
2206 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2207 current segment as an argument. (Ignored in all cases but VMS.)
2208 All callers and definitions changed.

2505 md_relax_table): Use default zero initialization.
2506 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2507 latter, instead of selecting with preprocessor conditionals.
2509 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2511 * configure.in: recognise all sparclite variants

2521 * expr.c (operand): If character other than comma or newline is a
2522 logical end-of-line character, use the newline case.
2523 From Eric Youngdale:
2524 (operand): Set X_add_number field for floating-point numbers.
2525 (operand): Treat zero byte as end-of-operand.
2527 * configure.in (per-target): Look for with_bfd_assembler option.
2528 For now, only accept "no", until the merge is done.
2530 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2531 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2532 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2533 * read.c: Finish conversion to S_* macros in the VMS only
2534 parts of the program. Add "const" modifier to hex_value.
2535 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2537 * expr.c: Add "const" modifier to hex_value.
2538 * symbols.c: Finish conversion to S_* macros in the VMS only
2539 parts of the program. Add "const" modifier to
2540 md_[long,short]_jump_size. Remove declaration of const_flag
2541 (which will be declared in obj-vms.h).
2542 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2543 Fix arguments to VMS_write_object_file.
2544 * config-gas.com: New file. Script for VMS systems to set up the
2545 configuration to build gas for VMS, and create config.status.
2546 * make-gas.com: Redone to work with new scheme.
2547 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2549 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2550 will swap bytes if needed on a big endian system. Use throughout
2552 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2553 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2554 types of malformed stabs. Change parsing algorithm so that we are
2555 more certain of having all of the information that we need on hand.
2556 * obj-vms.c (final_forward_reference): New function, used to help
2557 resolve the data types of as many struct elements as possible
2558 when some part of the struct is not fully defined by the compiler.

2561 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2562 as symbols as well in the object file. Look for external functions
2563 that start with "__vt.", and turn them into variables, since the
2564 g++ compiler is incapable of doing this.
2565 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2567 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2568 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2569 have the name of the source file yet.
2570 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2572 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2574 * read.c (s_data): Always use "data_section", since it'll map to
2575 SEG_DATA or SEG_E1 if needed.
2576 (s_lcomm): Likewise with bss_section.
2577 (s_fill): Use memset, not bzero.
2579 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2600 (section_alignment): Declare only if not BFD_ASSEMBLER.
2601 (big_section, reg_section, pass1_section, diff_section,
2602 absent_section, text_section, data_section, bss_section): If
2603 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2604 mapping to segT enum values.
2605 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2606 if these are used or defined, if BFD_ASSEMBLER.
2607 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2608 subseg_new split into two functions.
2609 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2611 * as.h (volatile): Don't define if already defined.
2612 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2614 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2615 declare with format attribute for -Wformat checking.
2617 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2619 * app.c, config/tc-*.c: Don't include read.h, since it is already
2622 * These are based on patches from Minh Tran-le
2623 <mtranle@paris.intellicorp.com>.
2624 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2625 obj_format coffbfd and gas_target i386coff for target.
2626 (i[34]86-*-isc*): New host (uses sysv).
2627 * config/i386aix.mt: Removed (no longer used).
2628 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2630 (LDFLAGS): Added, defined as -shlib.
2631 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2632 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2633 (DOT_LABEL_PREFIX): Define.
2634 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2635 name rather than L0\001.
2636 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2638 * symbols.c, symbols.h (local_bss_counter): Removed.
2639 * write.c (write_object_file): bss no longer uses
2640 local_bss_counter. Pass correct data and bss size to
2641 VMS_write_object_file.

2647 (size_section): Restored sanity check.
2648 (do_relocs_for): Base section address on s_paddr rather than
2649 computing it. Adjust a29k R_IHIHALF special case to account for
2650 section paddr (used to require paddr to be zero). If there are no
2651 reclos, set s_relptr to 0. Set relocation size in object_headers.
2652 (fill_section): Always set s_vaddr here, removing
2653 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2654 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2655 Set STYP_INFO for .comment.

2659 H_{SET,GET}_* macros.
2660 (do_linenos_for): Set lineno size in object_headers.
2661 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2662 set s_vaddr here. If string_byte_count remains 4, set it back to
2663 0, and only write strings out if there are some. Call
2664 fill_section before do_relocs_for and do_linenos_for.
2665 (obj_coff_section): Handle optional quoted second argument giving
2666 section characteristics.
2667 (obj_coff_bss): Added to handle .bss.
2668 (obj_coff_ident): Added to handle .ident (puts string in .comment

2688 (do_scrub_next_char): For \", return " not '.
2689 (symbol_chars): Now const.
2691 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2692 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2694 * config/obj-coff.h: Don't use #elif.
2696 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2697 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
2699 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
2701 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

2723 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2724 using ZERO_BASED_SEGMENTS.
2725 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2726 never set segment address for SEG_E2 (.bss) and don't write out
2727 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2728 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2729 definitions, and don't merge tags with non-tags. Check for .bf
2730 rather than just checking whether the second character is b and
2731 the third character is f.
2732 (obj_coff_val): gcc can generate values which we don't handle
2733 correctly; discard information for now, since it only affects the
2734 debugging information.
2735 (tag_find_or_name): Don't insert tags in the symbol table.
2736 (yank_symbols): Don't merge labels.
2737 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2880 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
2882 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2883 could be doing emulation.
2885 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2888 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2915 consistently const, and always initialized them. Included read.h.
2917 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2919 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2920 constant will not fit in an immediate field.
2921 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
2923 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

2940 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
2941 so widening works consistently.
2943 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
2945 * version.c: Put conditional "const" before version_string, not

2948 * app.c (do_scrub_next_char): Need double-\ before `000' to show
2949 printed rep of null character.
2951 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
2953 * obj-coffbfd.c (write_object_file): check return value of
2956 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2958 * Support for i386-sysv.
2959 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
2960 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
2961 be used to set them all to zero as was done before.
2962 (fill_section): segment addresses now set in write_object_file.
2963 (fill_section): Don't set STYP_NOLOAD for .bss section.
2964 (fixup_segment): 386 uses strange common symbol format.
2965 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
2966 compatibility with SVR3.2 linker.
2967 * configure.in: i386-sysv and i386-sco use coffbfd.
2969 * app.c (do_scrub_next_char): discard whitespace after a label.

2997 * tc-z8k.c: lots of bug fixes
2999 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3001 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3002 #elif, since it is not supported by old compilers.
3003 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3004 couple of expressions in tc-m68k.c.
3006 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3008 * read.c (cons): If NO_RELOC is defined, use it.
3010 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3012 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3014 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3015 local labels to start with a .) and set REGISTER_PREFIX to %.
3016 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3018 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3032 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3034 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3035 sections starting from zero, rather than making them consecutive.
3036 This makes subsequent reloc calculations easier, esp if the object
3037 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3038 allocate lcomm in .data rather than in .bss. It seems that some
3039 tools can't cope with a non-zero sized bss before linkage.
3041 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3043 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

3062 * Makefile.in (install): if $(tooldir) exists, install as in
3065 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3067 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3068 .word is < -32768 or > 32767. The -J flag causes the error to be
3069 ignored. This is to catch over-sized switches generated by gcc on
3070 systems which don't support the broken .word hack.
3071 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3072 write.c (fixup_segment): check for signed .word overflow if
3073 WARN_SIGNED_OVERFLOW_WORD.
3075 * write.c (fixup_segment): fixed missing parens in expression
3076 checking for byte or word overflow.

3092 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3094 * input-scrub.c (input_scrub_push): call input_file_begin, not
3096 messages.c (as_perror): print ": " between the passed in error and
3097 the strerror, like perror does.
3099 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

3102 From Steve Chamberlain:
3103 Makefile.in: Handle m68*-*-coff*.
3104 read.c, read.h: add mult argument to s_space
3106 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3107 Motorola and MIT syntax; gas can now assemble either type of
3109 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3117 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3119 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3122 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3124 * Makefile.in (LIBS): Include opcode library.

3149 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3151 * config/tc-m68k.c (init_table): Now const. Always include 68851
3152 data, so that "bc" is available to 68040 cache instructions.
3153 Added "tt0", "tt1", and 68ec030 variants.
3154 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3155 (enum _register): Added TT0, TT1.
3156 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3157 line number correctly in "internal error" messages. Don't print
3158 architecture-mismatch message for operand errors.
3160 From Colin Smith (colin@wrs.com):
3161 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

3183 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3184 has already been formatted (but may still contain %-characters).
3187 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3189 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3190 written with indirection on the last two operands, which can be
3191 either data or address registers. Added a new operand type 'r'
3192 which accepts either register type. Added '(' to notend stuff in
3193 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3212 their not having symbols associated.
3214 * tc-i960.c (norelax, instrument_branches): Default initializer is

3240 being used with args swapped, causing occasional lossage when
3241 refilling buffers after an include file.
3243 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
3245 * messages.c (as_tsktsk): Use correct ANSI form for stdarg

3251 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
3252 selected architecture, print a message saying so and listing what

3299 * expr.c (floating_constant): Separate "=-" to avoid confusing
3300 ancient or broken compilers.
3302 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
3303 processor/opcode mismatch, so reword the error message.
3304 (md_assemble): If no CPU has been set (even if FPU/PMMU
3305 characteristics have been), default to 68020. Don't need extra
3306 quotes around error string.

3364 * write.c (write_object_file): various changes to handle data in
3365 the BSS segment in much the same was as stuff in the DATA segment.
3367 * tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
3368 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
3369 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
3370 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put

3375 * expr.c(expr): allow SEG_REGISTER in expressions.
3376 * read.c(pseudo_set): register expressions can be the source of a
3378 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
3379 goto SEG_TEXT (if a.out)
3380 * write.c (write_object_file): If a.out don't use the old way for
3382 * config/obj-a.out (s_sect): complain if the user tries to use a
3383 subsegment with a value which might interfere with out -R hackery.
3384 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
3385 rather than use ugly if tree. (init_regtable): insert register
3386 names into symbol table.
3388 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
3390 * write.c (write_object_file): keep the fix_tail clean, which
3391 fixes a bug in -R where relocations were being lost.
3393 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
3395 * configure.in: recognize m680x0 as having sun3 emulation mode for

3418 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3420 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
3421 calc the base of relocs correctly.
3422 * tc-a29k.c (parse_operand): allow expressions to be in any section.
3424 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
3426 * as.c, write.c: use -K rather than -k for the broken word warning

3437 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3439 * write.c (write_object_file): For b.out format, round up section
3440 start addresses to match required alignment.
3442 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3444 * Makefile.in (install): Install into $(tooldir)/bin, since that's
3445 where gcc looks for it.
3447 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
3449 * Makefile.in: Changed some lines to be less confusing for some
3452 * input-file.c: Conditionalize on _IOFBF, not VMS.
3454 * read.c, write.c: Change a series of ifdef/elif to
3455 ifdef/else/ifdef etc.

3474 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
3476 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
3477 tc-m68k.h to te-sun3.h.
3479 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
3481 * configure.in: vxworks68 gets te-sun3.h.
3483 * expr.c: remove limitation that local_labels_dollar or
3484 local_labels_fb must be < 10.
3486 * symbols.c: remove local_labels_dollar, replace with a function
3487 interface for a sparse array. All users adjusted.
3489 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
3491 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3493 * doc/Makefile.in: commented out line for building as-all.texinfo.
3496 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
3498 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

3512 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3515 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3517 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3519 * expr.c (operand): if can't work out what sort of operand it is,
3520 then look through FLT_CHARS for a hint.
3522 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3524 * Makefile.in, configure.in: removed traces of namesubdir,
3525 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3526 copyrights to '92, changed some from Cygnus to FSF.
3528 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3529 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3530 copyrights to '92, changed some from Cygnus to FSF.
3532 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3534 * expr.c: If an expression is single comma, then return with
3535 SEG_ABSENT rather than an error - since the sparc front end does
3536 really strange things with things like fbge,a
3538 * as.h: include bfd.h if using many sections
3539 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3540 local labels didn't work.
3541 * listing.c (list_symbol_table): don't core dump when there's no
3543 * write.c, write.h: call fix_new with the right number of args on
3545 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3548 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3550 * app.c: MRI compatibility - allow single quote to start a string.
3551 * as.c: fix typo recently introduced.
3552 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3553 * expr.c: Much rewriting, to accomodate MRI syntax for
3554 expressions. Also easier to read now.
3555 * listing.c: Put back defuns
3556 * read.c: modified to accept MRI syntax, put back listing pseudo
3557 ops so that an assembler built with NO_LISTING ignores list ops
3559 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3560 machine is a SPARC or a 29K.
3561 * config/obj-aout.c: added s_sect pseudo op
3562 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3563 fill in the timestamp.
3564 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3565 anymore, define all the relocs which the tc-<x> bit will use so we
3566 can translate from them to the coff types.
3567 * config/tc-a29k.c: reloc_type isn't ane enum any more
3568 * config/tc-m68k.c: Added NO_RELOC definition.
3570 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3572 * Makefile.in: put header files before C source for TAGS; remove
3573 references to non-existent syscalls.h.
3575 * read.c, write.c subsegs.c: back out the .bss changes.
3577 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3579 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3583 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3585 * symbols.c (local_label_name): symbols now start with ^A.
3587 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3588 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3589 generate these sections. .align: will use NOP_OPCODE or 0
3590 for padding. This is just for being nice to the
3593 * expr.c (operand): changed to generate local label "\001L0"
3594 starting with a ^A so that it is recognized as a local label.
3596 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3598 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3599 i/o opcodes - inb, inw, outb and outw. string manipulation with
3600 att syntax - scmp, slod, smov, ssca, ssto.
3602 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3603 to just after .file .
3605 In obj_crawl_symbol_chain() where it tries to put the external
3606 symbols apart, with the condition:
3607 (!S_IS_DEFINED(symbolP) &&
3608 !S_IS_DEBUG(symbolP) &&
3609 !SF_GET_STATICS(symbolP))
3610 it was moving too many symbols out. So I switch it back to the
3612 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3614 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3615 so that we don't use the F_RELFLG which make the linker complain
3616 that somebody has stripped the relocation info.
3618 Also, the AIX ld program require that the relocation table
3619 is sorted by r_vaddr like the standard ATT assembler does.
3621 [he also changed the sizeof(struct ...)'s into the coff
3622 style FOOSZ macros. I'm not sure this is right, but I can't
3623 remember why. xoxorich.]
3625 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3627 * Makefile.in, configure.in, doc: use the doc. Build it, install
3630 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3632 * read.c: white space and comments only.
3634 * configure.in: use the new atof-ns32.c for ns32k.
3636 * write.c: comment change only.
3638 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3639 aren't yet integrated.
3641 * tc-i860.[hc]: blew off the dust. Something must still be done
3642 about conflicting relocation types.
3644 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3647 * tc-i960.c, tc-sparc.c: white space and comments only.
3649 * tc-a29k.h: delete duplicate macro definition.
3651 * new file atof-ns32k.c copied from hack's last unreleased gas.
3653 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3655 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3658 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3659 ChangeLog's prior to this are sketchy at best. I have logs.
3660 They just aren't ChangeLogs.
