1012 are also magic, and have special default flag settings.
1013 (obj_elf_frob_symbol): Since the return value from this function

1077 * Extensive changes to permit symbols to contain any expression
1078 type and to delay the computation of the expression until the
1079 value is actually needed. This permits setting symbols to values
1080 calculated based on object code size. Expressions were changed to
1081 no longer be in a section, to stop the overloading of segment and
1082 expression type that previously occurred.
1084 * as.c (big_section, pass1_section, diff_section, absent_section):
1086 (expr_section): Added (used for dummy symbols which hold

1170 (previous_section, previous_subsection): New vars.
1171 (obj_elf_section): Save current place in case DWARF code wants us
1172 to pop back to it. Handle unquoted section name as well as quoted
1173 section name. Don't crash on invalid strings.
1174 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2404 avoid some redefinition complaints on some systems.
2405 (const, volatile): Don't need these conditionally defined if we
2406 use CONST and VOLATILE from ansidecl.h.

2449 dropping a space immediately following an identifier.
2450 * expr.c, write.c: Rewrote assert expressions to not use multiple
2451 lines; I don't think that can be done portably.
2452 * config/tc-mips.c (macro): Use $AT if target register is zero in
2453 load instruction, which it can be for a floating point load.

2527 prototypes for all static functions. Moved existing minimal
2528 debugging format support info #ifndef OBJ_ECOFF blocks.

2579 * read.c (s_ignore): Don't declare is_end_of_line. It's
2580 redundant, and triggers a VMS gcc compiler bug.
2582 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2583 current segment as an argument. (Ignored in all cases but VMS.)
2584 All callers and definitions changed.

2878 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2880 * config/tc-sparc.c (architecture_requested, warn_on_bump,
2881 md_relax_table): Use default zero initialization.
2882 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2883 latter, instead of selecting with preprocessor conditionals.
2885 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2887 * configure.in: recognise all sparclite variants
2889 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2891 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
2892 accidentally changed to use subseg_change where it should have
2895 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2897 * expr.c (operand): If character other than comma or newline is a
2898 logical end-of-line character, use the newline case.
2899 From Eric Youngdale:
2900 (operand): Set X_add_number field for floating-point numbers.
2901 (operand): Treat zero byte as end-of-operand.
2903 * configure.in (per-target): Look for with_bfd_assembler option.
2904 For now, only accept "no", until the merge is done.
2906 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2907 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2908 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2909 * read.c: Finish conversion to S_* macros in the VMS only
2910 parts of the program. Add "const" modifier to hex_value.
2911 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2913 * expr.c: Add "const" modifier to hex_value.
2914 * symbols.c: Finish conversion to S_* macros in the VMS only
2915 parts of the program. Add "const" modifier to
2916 md_[long,short]_jump_size. Remove declaration of const_flag
2917 (which will be declared in obj-vms.h).
2918 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2919 Fix arguments to VMS_write_object_file.
2920 * config-gas.com: New file. Script for VMS systems to set up the
2921 configuration to build gas for VMS, and create config.status.
2922 * make-gas.com: Redone to work with new scheme.
2923 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2925 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2926 will swap bytes if needed on a big endian system. Use throughout
2928 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2929 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2930 types of malformed stabs. Change parsing algorithm so that we are
2931 more certain of having all of the information that we need on hand.
2932 * obj-vms.c (final_forward_reference): New function, used to help
2933 resolve the data types of as many struct elements as possible
2934 when some part of the struct is not fully defined by the compiler.
2935 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2937 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2938 as symbols as well in the object file. Look for external functions
2939 that start with "__vt.", and turn them into variables, since the
2940 g++ compiler is incapable of doing this.
2941 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2943 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2944 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2945 have the name of the source file yet.
2946 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2948 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2950 * read.c (s_data): Always use "data_section", since it'll map to
2951 SEG_DATA or SEG_E1 if needed.
2952 (s_lcomm): Likewise with bss_section.
2953 (s_fill): Use memset, not bzero.
2955 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2957 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

2976 (section_alignment): Declare only if not BFD_ASSEMBLER.
2977 (big_section, reg_section, pass1_section, diff_section,
2978 absent_section, text_section, data_section, bss_section): If
2979 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2980 mapping to segT enum values.
2981 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2982 if these are used or defined, if BFD_ASSEMBLER.
2983 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2984 subseg_new split into two functions.
2985 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2987 * as.h (volatile): Don't define if already defined.
2988 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2990 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2991 declare with format attribute for -Wformat checking.
2993 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2995 * app.c, config/tc-*.c: Don't include read.h, since it is already
2998 * These are based on patches from Minh Tran-le
2999 <mtranle@paris.intellicorp.com>.
3000 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3001 obj_format coffbfd and gas_target i386coff for target.
3002 (i[34]86-*-isc*): New host (uses sysv).
3003 * config/i386aix.mt: Removed (no longer used).
3004 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3006 (LDFLAGS): Added, defined as -shlib.
3007 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3008 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3009 (DOT_LABEL_PREFIX): Define.
3010 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3011 name rather than L0\001.
3012 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3014 * symbols.c, symbols.h (local_bss_counter): Removed.
3015 * write.c (write_object_file): bss no longer uses
3016 local_bss_counter. Pass correct data and bss size to
3017 VMS_write_object_file.

3023 (size_section): Restored sanity check.
3024 (do_relocs_for): Base section address on s_paddr rather than
3025 computing it. Adjust a29k R_IHIHALF special case to account for
3026 section paddr (used to require paddr to be zero). If there are no
3027 reclos, set s_relptr to 0. Set relocation size in object_headers.
3028 (fill_section): Always set s_vaddr here, removing
3029 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3030 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3031 Set STYP_INFO for .comment.
3032 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3033 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3035 H_{SET,GET}_* macros.
3036 (do_linenos_for): Set lineno size in object_headers.
3037 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3038 set s_vaddr here. If string_byte_count remains 4, set it back to
3039 0, and only write strings out if there are some. Call
3040 fill_section before do_relocs_for and do_linenos_for.
3041 (obj_coff_section): Handle optional quoted second argument giving
3042 section characteristics.
3043 (obj_coff_bss): Added to handle .bss.
3044 (obj_coff_ident): Added to handle .ident (puts string in .comment

3047 (fixup_mdeps): Change to segment. Call frag_wane after
3049 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3050 adjustment (already happened only for common symbols, but this is
3052 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
3053 * config/tc-i386.c (s_bss): Don't use if I386COFF.

3064 (do_scrub_next_char): For \", return " not '.
3065 (symbol_chars): Now const.
3067 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3068 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3070 * config/obj-coff.h: Don't use #elif.
3072 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3073 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3075 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

3099 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3100 using ZERO_BASED_SEGMENTS.
3101 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3102 never set segment address for SEG_E2 (.bss) and don't write out
3103 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3104 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3105 definitions, and don't merge tags with non-tags. Check for .bf
3106 rather than just checking whether the second character is b and
3107 the third character is f.
3108 (obj_coff_val): gcc can generate values which we don't handle
3109 correctly; discard information for now, since it only affects the
3110 debugging information.

3112 (yank_symbols): Don't merge labels.
3113 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3295 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3296 constant will not fit in an immediate field.
3297 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

3332 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3334 * Support for i386-sysv.
3335 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3336 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3337 be used to set them all to zero as was done before.
3338 (fill_section): segment addresses now set in write_object_file.
3339 (fill_section): Don't set STYP_NOLOAD for .bss section.
3340 (fixup_segment): 386 uses strange common symbol format.
3341 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
3342 compatibility with SVR3.2 linker.
3343 * configure.in: i386-sysv and i386-sco use coffbfd.

3355 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
3356 support for C source listings. (obj_coff_endef): look in the right
3357 part of the symbol for the symbol name
3359 * tc-m68k.c (get_num): make it work for all segments, not just the
3362 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

3373 * tc-z8k.c: lots of bug fixes
3375 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3377 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3378 #elif, since it is not supported by old compilers.
3379 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3380 couple of expressions in tc-m68k.c.
3382 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3384 * read.c (cons): If NO_RELOC is defined, use it.
3386 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3388 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3390 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3391 local labels to start with a .) and set REGISTER_PREFIX to %.
3392 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

3410 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3411 sections starting from zero, rather than making them consecutive.
3412 This makes subsequent reloc calculations easier, esp if the object
3413 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3414 allocate lcomm in .data rather than in .bss. It seems that some
3415 tools can't cope with a non-zero sized bss before linkage.
3417 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3419 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

3441 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3443 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3444 .word is < -32768 or > 32767. The -J flag causes the error to be
3445 ignored. This is to catch over-sized switches generated by gcc on
3446 systems which don't support the broken .word hack.
3447 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3448 write.c (fixup_segment): check for signed .word overflow if
3449 WARN_SIGNED_OVERFLOW_WORD.

3468 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3470 * input-scrub.c (input_scrub_push): call input_file_begin, not
3472 messages.c (as_perror): print ": " between the passed in error and
3473 the strerror, like perror does.
3475 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

3478 From Steve Chamberlain:
3479 Makefile.in: Handle m68*-*-coff*.
3480 read.c, read.h: add mult argument to s_space
3482 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3483 Motorola and MIT syntax; gas can now assemble either type of
3485 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3493 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3495 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3498 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3500 * Makefile.in (LIBS): Include opcode library.

3525 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3527 * config/tc-m68k.c (init_table): Now const. Always include 68851
3528 data, so that "bc" is available to 68040 cache instructions.
3529 Added "tt0", "tt1", and 68ec030 variants.
3530 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3531 (enum _register): Added TT0, TT1.
3532 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3533 line number correctly in "internal error" messages. Don't print
3534 architecture-mismatch message for operand errors.
3536 From Colin Smith (colin@wrs.com):
3537 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

3559 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3560 has already been formatted (but may still contain %-characters).
3563 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3565 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3566 written with indirection on the last two operands, which can be
3567 either data or address registers. Added a new operand type 'r'
3568 which accepts either register type. Added '(' to notend stuff in
3569 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3807 * Makefile.in: do not print recursion lines.
3809 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3811 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
3813 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3815 * write.c (write_object_file): For b.out format, round up section
3816 start addresses to match required alignment.
3818 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3820 * Makefile.in (install): Install into $(tooldir)/bin, since that's
3821 where gcc looks for it.
3823 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
3825 * Makefile.in: Changed some lines to be less confusing for some
3828 * input-file.c: Conditionalize on _IOFBF, not VMS.
3830 * read.c, write.c: Change a series of ifdef/elif to
3831 ifdef/else/ifdef etc.
3833 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
3835 * symbols.c (fb_label_init): fix sizeof to memset.
3837 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
3839 * Makefile.in: install the man page.
3841 * Makefile.in: pass down MAKEINFO explicitly on info.
3843 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
3845 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3847 * flonum-const.c: renamed flonum-konst.c to stop dos name
3850 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
3852 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
3853 tc-m68k.h to te-sun3.h.
3855 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
3857 * configure.in: vxworks68 gets te-sun3.h.
3859 * expr.c: remove limitation that local_labels_dollar or
3860 local_labels_fb must be < 10.
3862 * symbols.c: remove local_labels_dollar, replace with a function
3863 interface for a sparse array. All users adjusted.
3865 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
3867 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3869 * doc/Makefile.in: commented out line for building as-all.texinfo.
3872 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
3874 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
3876 * Makefile.in: added check target.
3878 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3880 * Makefile.in: added tooldir and program_prefix.
3882 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
3884 * write.{c,h} (fix_new): Make these declarations consistent.
3886 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
3888 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3891 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3893 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3895 * expr.c (operand): if can't work out what sort of operand it is,
3896 then look through FLT_CHARS for a hint.
3898 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3900 * Makefile.in, configure.in: removed traces of namesubdir,
3901 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3902 copyrights to '92, changed some from Cygnus to FSF.
3904 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3905 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3906 copyrights to '92, changed some from Cygnus to FSF.
3908 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3910 * expr.c: If an expression is single comma, then return with
3911 SEG_ABSENT rather than an error - since the sparc front end does
3912 really strange things with things like fbge,a
3914 * as.h: include bfd.h if using many sections
3915 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3916 local labels didn't work.
3917 * listing.c (list_symbol_table): don't core dump when there's no
3919 * write.c, write.h: call fix_new with the right number of args on
3921 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3924 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3926 * app.c: MRI compatibility - allow single quote to start a string.
3927 * as.c: fix typo recently introduced.
3928 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3929 * expr.c: Much rewriting, to accomodate MRI syntax for
3930 expressions. Also easier to read now.
3931 * listing.c: Put back defuns
3932 * read.c: modified to accept MRI syntax, put back listing pseudo
3933 ops so that an assembler built with NO_LISTING ignores list ops
3935 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3936 machine is a SPARC or a 29K.
3937 * config/obj-aout.c: added s_sect pseudo op
3938 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3939 fill in the timestamp.
3940 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3941 anymore, define all the relocs which the tc-<x> bit will use so we
3942 can translate from them to the coff types.
3943 * config/tc-a29k.c: reloc_type isn't ane enum any more
3944 * config/tc-m68k.c: Added NO_RELOC definition.
3946 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3948 * Makefile.in: put header files before C source for TAGS; remove
3949 references to non-existent syscalls.h.
3951 * read.c, write.c subsegs.c: back out the .bss changes.
3953 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3955 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3959 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3961 * symbols.c (local_label_name): symbols now start with ^A.
3963 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3964 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3965 generate these sections. .align: will use NOP_OPCODE or 0
3966 for padding. This is just for being nice to the
3969 * expr.c (operand): changed to generate local label "\001L0"
3970 starting with a ^A so that it is recognized as a local label.
3972 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3974 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3975 i/o opcodes - inb, inw, outb and outw. string manipulation with
3976 att syntax - scmp, slod, smov, ssca, ssto.
3978 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3979 to just after .file .
3981 In obj_crawl_symbol_chain() where it tries to put the external
3982 symbols apart, with the condition:
3983 (!S_IS_DEFINED(symbolP) &&
3984 !S_IS_DEBUG(symbolP) &&
3985 !SF_GET_STATICS(symbolP))
3986 it was moving too many symbols out. So I switch it back to the
3988 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3990 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3991 so that we don't use the F_RELFLG which make the linker complain
3992 that somebody has stripped the relocation info.
3994 Also, the AIX ld program require that the relocation table
3995 is sorted by r_vaddr like the standard ATT assembler does.
3997 [he also changed the sizeof(struct ...)'s into the coff
3998 style FOOSZ macros. I'm not sure this is right, but I can't
3999 remember why. xoxorich.]
4001 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4003 * Makefile.in, configure.in, doc: use the doc. Build it, install
4006 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4008 * read.c: white space and comments only.
4010 * configure.in: use the new atof-ns32.c for ns32k.
4012 * write.c: comment change only.
4014 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4015 aren't yet integrated.
4017 * tc-i860.[hc]: blew off the dust. Something must still be done
4018 about conflicting relocation types.
4020 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4023 * tc-i960.c, tc-sparc.c: white space and comments only.
4025 * tc-a29k.h: delete duplicate macro definition.
4027 * new file atof-ns32k.c copied from hack's last unreleased gas.
4029 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4031 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4034 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4035 ChangeLog's prior to this are sketchy at best. I have logs.
4036 They just aren't ChangeLogs.
