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

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

440 segment rather than sy_forward.
441 * config/obj-vms.c (VMS_Check_For_Main): Don't initialize
442 sy_forward; do initialize sy_resolved and sy_resolving.
443 * config/tc-hppa.h (STAB_FIXUP): Use sy_value, not sy_forward.
445 * Changes to keep a full expression as the value of a symbol, not

1534 avoid some redefinition complaints on some systems.
1535 (const, volatile): Don't need these conditionally defined if we
1536 use CONST and VOLATILE from ansidecl.h.
1537 (seg_name): Use CONST, not const.

1574 * Makefile.in (targ-cpu.o): Depend on config.h.
1576 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
1578 * app.c (do_scrub_next_char): Added new state, 9, to avoid
1579 dropping a space immediately following an identifier.
1580 * expr.c, write.c: Rewrote assert expressions to not use multiple
1581 lines; I don't think that can be done portably.
1582 * config/tc-mips.c (macro): Use $AT if target register is zero in
1583 load instruction, which it can be for a floating point load.
1585 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

1606 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
1608 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
1609 to be on a single line.

1657 prototypes for all static functions. Moved existing minimal
1658 debugging format support info #ifndef OBJ_ECOFF blocks.

1709 * read.c (s_ignore): Don't declare is_end_of_line. It's
1710 redundant, and triggers a VMS gcc compiler bug.
1712 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1713 current segment as an argument. (Ignored in all cases but VMS.)
1714 All callers and definitions changed.

2011 md_relax_table): Use default zero initialization.
2012 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2013 latter, instead of selecting with preprocessor conditionals.
2015 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2017 * configure.in: recognise all sparclite variants

2027 * expr.c (operand): If character other than comma or newline is a
2028 logical end-of-line character, use the newline case.
2029 From Eric Youngdale:
2030 (operand): Set X_add_number field for floating-point numbers.
2031 (operand): Treat zero byte as end-of-operand.
2033 * configure.in (per-target): Look for with_bfd_assembler option.
2034 For now, only accept "no", until the merge is done.
2036 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2037 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2038 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2039 * read.c: Finish conversion to S_* macros in the VMS only
2040 parts of the program. Add "const" modifier to hex_value.

2043 * expr.c: Add "const" modifier to hex_value.
2044 * symbols.c: Finish conversion to S_* macros in the VMS only
2045 parts of the program. Add "const" modifier to
2046 md_[long,short]_jump_size. Remove declaration of const_flag
2047 (which will be declared in obj-vms.h).
2048 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2049 Fix arguments to VMS_write_object_file.
2050 * config-gas.com: New file. Script for VMS systems to set up the
2051 configuration to build gas for VMS, and create config.status.
2052 * make-gas.com: Redone to work with new scheme.
2053 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2055 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2056 will swap bytes if needed on a big endian system. Use throughout
2058 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2059 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2060 types of malformed stabs. Change parsing algorithm so that we are
2061 more certain of having all of the information that we need on hand.
2062 * obj-vms.c (final_forward_reference): New function, used to help
2063 resolve the data types of as many struct elements as possible
2064 when some part of the struct is not fully defined by the compiler.

2067 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2068 as symbols as well in the object file. Look for external functions
2069 that start with "__vt.", and turn them into variables, since the
2070 g++ compiler is incapable of doing this.
2071 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2073 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2074 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2075 have the name of the source file yet.
2076 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2078 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2080 * read.c (s_data): Always use "data_section", since it'll map to
2081 SEG_DATA or SEG_E1 if needed.
2082 (s_lcomm): Likewise with bss_section.
2083 (s_fill): Use memset, not bzero.
2085 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2106 (section_alignment): Declare only if not BFD_ASSEMBLER.
2107 (big_section, reg_section, pass1_section, diff_section,
2108 absent_section, text_section, data_section, bss_section): If
2109 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2110 mapping to segT enum values.
2111 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2112 if these are used or defined, if BFD_ASSEMBLER.
2113 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2114 subseg_new split into two functions.
2115 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2117 * as.h (volatile): Don't define if already defined.
2118 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2120 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2121 declare with format attribute for -Wformat checking.
2123 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2125 * app.c, config/tc-*.c: Don't include read.h, since it is already
2128 * These are based on patches from Minh Tran-le
2129 <mtranle@paris.intellicorp.com>.
2130 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2131 obj_format coffbfd and gas_target i386coff for target.
2132 (i[34]86-*-isc*): New host (uses sysv).
2133 * config/i386aix.mt: Removed (no longer used).
2134 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2136 (LDFLAGS): Added, defined as -shlib.
2137 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2138 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2139 (DOT_LABEL_PREFIX): Define.
2140 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2141 name rather than L0\001.
2142 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2144 * symbols.c, symbols.h (local_bss_counter): Removed.
2145 * write.c (write_object_file): bss no longer uses

2153 (size_section): Restored sanity check.
2154 (do_relocs_for): Base section address on s_paddr rather than
2155 computing it. Adjust a29k R_IHIHALF special case to account for
2156 section paddr (used to require paddr to be zero). If there are no
2157 reclos, set s_relptr to 0. Set relocation size in object_headers.
2158 (fill_section): Always set s_vaddr here, removing
2159 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2160 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2161 Set STYP_INFO for .comment.

2165 H_{SET,GET}_* macros.
2166 (do_linenos_for): Set lineno size in object_headers.
2167 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2168 set s_vaddr here. If string_byte_count remains 4, set it back to
2169 0, and only write strings out if there are some. Call
2170 fill_section before do_relocs_for and do_linenos_for.
2171 (obj_coff_section): Handle optional quoted second argument giving
2172 section characteristics.
2173 (obj_coff_bss): Added to handle .bss.
2174 (obj_coff_ident): Added to handle .ident (puts string in .comment

2194 (do_scrub_next_char): For \", return " not '.
2195 (symbol_chars): Now const.
2197 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2198 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2200 * config/obj-coff.h: Don't use #elif.
2202 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2203 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2229 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2230 using ZERO_BASED_SEGMENTS.
2231 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2232 never set segment address for SEG_E2 (.bss) and don't write out
2233 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2234 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2235 definitions, and don't merge tags with non-tags. Check for .bf
2236 rather than just checking whether the second character is b and
2237 the third character is f.
2238 (obj_coff_val): gcc can generate values which we don't handle
2239 correctly; discard information for now, since it only affects the
2240 debugging information.
2241 (tag_find_or_name): Don't insert tags in the symbol table.
2242 (yank_symbols): Don't merge labels.
2243 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2446 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
2447 so widening works consistently.
2449 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
2451 * version.c: Put conditional "const" before version_string, not
2452 before dummy function for VMS. Now version 1.91.03.
2454 * app.c (do_scrub_next_char): Need double-\ before `000' to show
2455 printed rep of null character.
2457 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
2459 * obj-coffbfd.c (write_object_file): check return value of
2462 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2464 * Support for i386-sysv.
2465 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
2466 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
2467 be used to set them all to zero as was done before.
2468 (fill_section): segment addresses now set in write_object_file.
2469 (fill_section): Don't set STYP_NOLOAD for .bss section.
2470 (fixup_segment): 386 uses strange common symbol format.
2471 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
2472 compatibility with SVR3.2 linker.
2473 * configure.in: i386-sysv and i386-sco use coffbfd.

2503 * tc-z8k.c: lots of bug fixes
2505 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2507 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2508 #elif, since it is not supported by old compilers.
2509 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2510 couple of expressions in tc-m68k.c.
2512 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2514 * read.c (cons): If NO_RELOC is defined, use it.
2516 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2518 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2520 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2521 local labels to start with a .) and set REGISTER_PREFIX to %.
2522 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

2540 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2541 sections starting from zero, rather than making them consecutive.
2542 This makes subsequent reloc calculations easier, esp if the object
2543 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2544 allocate lcomm in .data rather than in .bss. It seems that some
2545 tools can't cope with a non-zero sized bss before linkage.
2547 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2549 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2568 * Makefile.in (install): if $(tooldir) exists, install as in
2571 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2573 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2574 .word is < -32768 or > 32767. The -J flag causes the error to be
2575 ignored. This is to catch over-sized switches generated by gcc on
2576 systems which don't support the broken .word hack.
2577 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2578 write.c (fixup_segment): check for signed .word overflow if
2579 WARN_SIGNED_OVERFLOW_WORD.

2598 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2600 * input-scrub.c (input_scrub_push): call input_file_begin, not
2602 messages.c (as_perror): print ": " between the passed in error and
2603 the strerror, like perror does.
2605 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2608 From Steve Chamberlain:
2609 Makefile.in: Handle m68*-*-coff*.
2610 read.c, read.h: add mult argument to s_space
2612 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2613 Motorola and MIT syntax; gas can now assemble either type of
2615 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2622 (fixup_segment) set fx_subsy to 0.
2623 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2625 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2628 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2630 * Makefile.in (LIBS): Include opcode library.

2655 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2657 * config/tc-m68k.c (init_table): Now const. Always include 68851
2658 data, so that "bc" is available to 68040 cache instructions.
2659 Added "tt0", "tt1", and 68ec030 variants.
2660 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2661 (enum _register): Added TT0, TT1.
2662 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2663 line number correctly in "internal error" messages. Don't print
2664 architecture-mismatch message for operand errors.
2666 From Colin Smith (colin@wrs.com):
2667 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2668 than install_operand.

2689 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2690 has already been formatted (but may still contain %-characters).
2693 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2695 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2696 written with indirection on the last two operands, which can be
2697 either data or address registers. Added a new operand type 'r'
2698 which accepts either register type. Added '(' to notend stuff in
2699 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2746 being used with args swapped, causing occasional lossage when
2747 refilling buffers after an include file.

2806 ancient or broken compilers.
2808 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
2809 processor/opcode mismatch, so reword the error message.

2910 * configure.in: Recognize sparclite as a sparc variant.
2912 * tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
2915 Tue May 26 16:47:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2917 * config/tc-a29k.c: lint

2924 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2926 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
2927 calc the base of relocs correctly.
2928 * tc-a29k.c (parse_operand): allow expressions to be in any section.
2930 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
2932 * as.c, write.c: use -K rather than -k for the broken word warning
2935 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
2937 * Makefile.in: do not print recursion lines.
2939 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2941 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
2943 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
2945 * write.c (write_object_file): For b.out format, round up section
2946 start addresses to match required alignment.
2948 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
2950 * Makefile.in (install): Install into $(tooldir)/bin, since that's
2951 where gcc looks for it.
2953 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
2955 * Makefile.in: Changed some lines to be less confusing for some
2958 * input-file.c: Conditionalize on _IOFBF, not VMS.
2960 * read.c, write.c: Change a series of ifdef/elif to
2961 ifdef/else/ifdef etc.
2963 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
2965 * symbols.c (fb_label_init): fix sizeof to memset.
2967 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
2969 * Makefile.in: install the man page.
2971 * Makefile.in: pass down MAKEINFO explicitly on info.

2975 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2977 * flonum-const.c: renamed flonum-konst.c to stop dos name
2980 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
2982 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
2983 tc-m68k.h to te-sun3.h.
2985 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
2987 * configure.in: vxworks68 gets te-sun3.h.
2989 * expr.c: remove limitation that local_labels_dollar or
2990 local_labels_fb must be < 10.
2992 * symbols.c: remove local_labels_dollar, replace with a function
2993 interface for a sparse array. All users adjusted.
2995 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
2997 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2999 * doc/Makefile.in: commented out line for building as-all.texinfo.
3002 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
3004 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

3016 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
3018 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3021 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3023 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3025 * expr.c (operand): if can't work out what sort of operand it is,
3026 then look through FLT_CHARS for a hint.
3028 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3030 * Makefile.in, configure.in: removed traces of namesubdir,
3031 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3032 copyrights to '92, changed some from Cygnus to FSF.
3034 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3035 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3036 copyrights to '92, changed some from Cygnus to FSF.
3038 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3040 * expr.c: If an expression is single comma, then return with
3041 SEG_ABSENT rather than an error - since the sparc front end does
3042 really strange things with things like fbge,a
3044 * as.h: include bfd.h if using many sections
3045 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3046 local labels didn't work.
3047 * listing.c (list_symbol_table): don't core dump when there's no
3049 * write.c, write.h: call fix_new with the right number of args on
3051 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3054 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3056 * app.c: MRI compatibility - allow single quote to start a string.
3057 * as.c: fix typo recently introduced.
3058 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3059 * expr.c: Much rewriting, to accomodate MRI syntax for
3060 expressions. Also easier to read now.
3061 * listing.c: Put back defuns
3062 * read.c: modified to accept MRI syntax, put back listing pseudo
3063 ops so that an assembler built with NO_LISTING ignores list ops
3065 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3066 machine is a SPARC or a 29K.
3067 * config/obj-aout.c: added s_sect pseudo op
3068 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3069 fill in the timestamp.
3070 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3071 anymore, define all the relocs which the tc-<x> bit will use so we
3072 can translate from them to the coff types.
3073 * config/tc-a29k.c: reloc_type isn't ane enum any more
3074 * config/tc-m68k.c: Added NO_RELOC definition.
3076 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3078 * Makefile.in: put header files before C source for TAGS; remove
3079 references to non-existent syscalls.h.
3081 * read.c, write.c subsegs.c: back out the .bss changes.
3083 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3085 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3089 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3091 * symbols.c (local_label_name): symbols now start with ^A.
3093 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3094 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3095 generate these sections. .align: will use NOP_OPCODE or 0
3096 for padding. This is just for being nice to the
3099 * expr.c (operand): changed to generate local label "\001L0"
3100 starting with a ^A so that it is recognized as a local label.
3102 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3104 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3105 i/o opcodes - inb, inw, outb and outw. string manipulation with
3106 att syntax - scmp, slod, smov, ssca, ssto.
3108 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3109 to just after .file .
3111 In obj_crawl_symbol_chain() where it tries to put the external
3112 symbols apart, with the condition:
3113 (!S_IS_DEFINED(symbolP) &&
3114 !S_IS_DEBUG(symbolP) &&
3115 !SF_GET_STATICS(symbolP))
3116 it was moving too many symbols out. So I switch it back to the
3118 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3120 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3121 so that we don't use the F_RELFLG which make the linker complain
3122 that somebody has stripped the relocation info.
3124 Also, the AIX ld program require that the relocation table
3125 is sorted by r_vaddr like the standard ATT assembler does.
3127 [he also changed the sizeof(struct ...)'s into the coff
3128 style FOOSZ macros. I'm not sure this is right, but I can't
3129 remember why. xoxorich.]
3131 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3133 * Makefile.in, configure.in, doc: use the doc. Build it, install
3136 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3138 * read.c: white space and comments only.
3140 * configure.in: use the new atof-ns32.c for ns32k.
3142 * write.c: comment change only.
3144 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3145 aren't yet integrated.
3147 * tc-i860.[hc]: blew off the dust. Something must still be done
3148 about conflicting relocation types.
3150 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3153 * tc-i960.c, tc-sparc.c: white space and comments only.
3155 * tc-a29k.h: delete duplicate macro definition.
3157 * new file atof-ns32k.c copied from hack's last unreleased gas.
3159 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3161 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3164 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3165 ChangeLog's prior to this are sketchy at best. I have logs.
3166 They just aren't ChangeLogs.
