290 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
292 * Extensive changes to permit symbols to contain any expression
293 type and to delay the computation of the expression until the
294 value is actually needed. This permits setting symbols to values
295 calculated based on object code size. Expressions were changed to
296 no longer be in a section, to stop the overloading of segment and
297 expression type that previously occurred.

410 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when

426 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
428 * read.c (float_cons): Simplified parsing logic. If
429 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
431 * symbols.c (colon): Rather than a special case for TC_HPPA,
432 use new macro tc_frob_label.
433 * config/tc-hppa.h (tc_frob_label): Define.

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

1619 avoid some redefinition complaints on some systems.
1620 (const, volatile): Don't need these conditionally defined if we
1621 use CONST and VOLATILE from ansidecl.h.
1622 (seg_name): Use CONST, not const.
1624 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
1626 * config/tc-mips.c: Reindented to GNU standards.

1630 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
1631 (fixup_segment): Add a29k special case; the linker is not prepared
1632 to see a segment offset here.

1637 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1639 * Makefile.in: add dvi target; as-$(config).texinfo might live in

1659 * Makefile.in (targ-cpu.o): Depend on config.h.
1661 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
1663 * app.c (do_scrub_next_char): Added new state, 9, to avoid
1664 dropping a space immediately following an identifier.
1665 * expr.c, write.c: Rewrote assert expressions to not use multiple
1666 lines; I don't think that can be done portably.
1667 * config/tc-mips.c (macro): Use $AT if target register is zero in
1668 load instruction, which it can be for a floating point load.
1670 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

1691 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
1693 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
1694 to be on a single line.

1742 prototypes for all static functions. Moved existing minimal
1743 debugging format support info #ifndef OBJ_ECOFF blocks.

1747 (tc_get_register): Renamed from get_register, and made non-static.
1749 * config/mips-big.mt, config/mips-lit.mt: New files. Define

1794 * read.c (s_ignore): Don't declare is_end_of_line. It's
1795 redundant, and triggers a VMS gcc compiler bug.
1797 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1798 current segment as an argument. (Ignored in all cases but VMS.)
1799 All callers and definitions changed.

2096 md_relax_table): Use default zero initialization.
2097 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2098 latter, instead of selecting with preprocessor conditionals.
2100 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2102 * configure.in: recognise all sparclite variants

2112 * expr.c (operand): If character other than comma or newline is a
2113 logical end-of-line character, use the newline case.
2114 From Eric Youngdale:
2115 (operand): Set X_add_number field for floating-point numbers.
2116 (operand): Treat zero byte as end-of-operand.
2118 * configure.in (per-target): Look for with_bfd_assembler option.
2119 For now, only accept "no", until the merge is done.
2121 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2122 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

2128 * expr.c: Add "const" modifier to hex_value.
2129 * symbols.c: Finish conversion to S_* macros in the VMS only
2130 parts of the program. Add "const" modifier to
2131 md_[long,short]_jump_size. Remove declaration of const_flag
2132 (which will be declared in obj-vms.h).
2133 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2134 Fix arguments to VMS_write_object_file.
2135 * config-gas.com: New file. Script for VMS systems to set up the
2136 configuration to build gas for VMS, and create config.status.
2137 * make-gas.com: Redone to work with new scheme.
2138 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2140 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2141 will swap bytes if needed on a big endian system. Use throughout
2143 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2144 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2145 types of malformed stabs. Change parsing algorithm so that we are
2146 more certain of having all of the information that we need on hand.
2147 * obj-vms.c (final_forward_reference): New function, used to help
2148 resolve the data types of as many struct elements as possible
2149 when some part of the struct is not fully defined by the compiler.

2152 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2153 as symbols as well in the object file. Look for external functions

2155 g++ compiler is incapable of doing this.
2156 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2158 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2159 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2160 have the name of the source file yet.
2161 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2163 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2165 * read.c (s_data): Always use "data_section", since it'll map to
2166 SEG_DATA or SEG_E1 if needed.
2167 (s_lcomm): Likewise with bss_section.
2168 (s_fill): Use memset, not bzero.
2170 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2192 (big_section, reg_section, pass1_section, diff_section,
2193 absent_section, text_section, data_section, bss_section): If
2194 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2195 mapping to segT enum values.
2196 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2197 if these are used or defined, if BFD_ASSEMBLER.
2198 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2199 subseg_new split into two functions.
2200 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2202 * as.h (volatile): Don't define if already defined.
2203 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2205 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2206 declare with format attribute for -Wformat checking.
2208 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2210 * app.c, config/tc-*.c: Don't include read.h, since it is already
2213 * These are based on patches from Minh Tran-le
2214 <mtranle@paris.intellicorp.com>.
2215 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2216 obj_format coffbfd and gas_target i386coff for target.
2217 (i[34]86-*-isc*): New host (uses sysv).
2218 * config/i386aix.mt: Removed (no longer used).
2219 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2221 (LDFLAGS): Added, defined as -shlib.
2222 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2223 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2224 (DOT_LABEL_PREFIX): Define.

2238 (size_section): Restored sanity check.
2239 (do_relocs_for): Base section address on s_paddr rather than
2240 computing it. Adjust a29k R_IHIHALF special case to account for
2241 section paddr (used to require paddr to be zero). If there are no
2242 reclos, set s_relptr to 0. Set relocation size in object_headers.
2243 (fill_section): Always set s_vaddr here, removing
2244 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2245 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2246 Set STYP_INFO for .comment.
2247 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
2248 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

2250 H_{SET,GET}_* macros.
2251 (do_linenos_for): Set lineno size in object_headers.
2252 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2253 set s_vaddr here. If string_byte_count remains 4, set it back to
2254 0, and only write strings out if there are some. Call
2255 fill_section before do_relocs_for and do_linenos_for.
2256 (obj_coff_section): Handle optional quoted second argument giving
2257 section characteristics.
2258 (obj_coff_bss): Added to handle .bss.
2259 (obj_coff_ident): Added to handle .ident (puts string in .comment

2279 (do_scrub_next_char): For \", return " not '.
2280 (symbol_chars): Now const.
2282 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2283 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2285 * config/obj-coff.h: Don't use #elif.
2287 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2288 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
2290 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
2292 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

2312 SEG_BSS, fill with NOP_OPCODE.
2313 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
2314 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2315 using ZERO_BASED_SEGMENTS.
2316 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2317 never set segment address for SEG_E2 (.bss) and don't write out
2318 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2319 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2320 definitions, and don't merge tags with non-tags. Check for .bf
2321 rather than just checking whether the second character is b and
2322 the third character is f.
2323 (obj_coff_val): gcc can generate values which we don't handle
2324 correctly; discard information for now, since it only affects the
2325 debugging information.
2326 (tag_find_or_name): Don't insert tags in the symbol table.
2327 (yank_symbols): Don't merge labels.
2328 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2348 power-of-two alignment for .align.
2350 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
2351 and leave everything else alone.

2383 options. Updated options documentation for m68k. Some minor
2384 wording/punctuation changes.
2386 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2388 * configure.in: Accept target OS "vms".

2440 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
2442 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
2445 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.

2474 could be doing emulation.
2476 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2479 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2508 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2510 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2511 constant will not fit in an immediate field.
2512 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2549 * Support for i386-sysv.
2550 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2592 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2593 #elif, since it is not supported by old compilers.
2594 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2595 couple of expressions in tc-m68k.c.
2597 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2599 * read.c (cons): If NO_RELOC is defined, use it.
2601 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2603 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2605 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2606 local labels to start with a .) and set REGISTER_PREFIX to %.
2607 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

2623 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2625 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2626 sections starting from zero, rather than making them consecutive.
2627 This makes subsequent reloc calculations easier, esp if the object
2628 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2629 allocate lcomm in .data rather than in .bss. It seems that some
2630 tools can't cope with a non-zero sized bss before linkage.
2632 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2634 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2653 * Makefile.in (install): if $(tooldir) exists, install as in
2656 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2658 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2659 .word is < -32768 or > 32767. The -J flag causes the error to be
2660 ignored. This is to catch over-sized switches generated by gcc on
2661 systems which don't support the broken .word hack.
2662 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2663 write.c (fixup_segment): check for signed .word overflow if
2664 WARN_SIGNED_OVERFLOW_WORD.
2666 * write.c (fixup_segment): fixed missing parens in expression
2667 checking for byte or word overflow.

2683 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2685 * input-scrub.c (input_scrub_push): call input_file_begin, not
2687 messages.c (as_perror): print ": " between the passed in error and
2688 the strerror, like perror does.
2690 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
2692 * Makefile.in: use gas_target instead of modifying target_cpu.
2693 From Steve Chamberlain:
2694 Makefile.in: Handle m68*-*-coff*.
2695 read.c, read.h: add mult argument to s_space
2697 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2698 Motorola and MIT syntax; gas can now assemble either type of
2700 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2706 (write_object_file) call fixup_mdeps
2707 (fixup_segment) set fx_subsy to 0.
2708 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2710 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2713 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2715 * Makefile.in (LIBS): Include opcode library.
2717 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

2737 tc-i960.c (md_ri_to_chars): Always output bout object file in
2738 little endian byte order (used to use endianness of host).
2740 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2742 * config/tc-m68k.c (init_table): Now const. Always include 68851
2743 data, so that "bc" is available to 68040 cache instructions.
2744 Added "tt0", "tt1", and 68ec030 variants.
2745 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2746 (enum _register): Added TT0, TT1.
2747 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2748 line number correctly in "internal error" messages. Don't print
2749 architecture-mismatch message for operand errors.
2751 From Colin Smith (colin@wrs.com):
2752 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2753 than install_operand.

2757 * listing.c (buffer_line): rewind to the start of include
2758 files, they might be included twice.

2767 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
2769 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
2770 so that we can assemble hand-written libgcc code.
2772 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2774 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2775 has already been formatted (but may still contain %-characters).
2778 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2780 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2781 written with indirection on the last two operands, which can be
2782 either data or address registers. Added a new operand type 'r'
2783 which accepts either register type. Added '(' to notend stuff in
2784 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
2786 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
2788 * as.h (enum _relax_state): Start off at one, not zero, to better

2802 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
2803 their not having symbols associated.
2805 * tc-i960.c (norelax, instrument_branches): Default initializer is
2807 (linkrelax): Delete variable definition.

2830 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
2831 being used with args swapped, causing occasional lossage when
2832 refilling buffers after an include file.
2834 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
2836 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
2837 version. Discard bogus DONTDEF version.
2838 (as_warn, as_bad, as_fatal): Likewise.
2840 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
2842 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
2843 selected architecture, print a message saying so and listing what

2884 fx_offset into account.
2886 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
2888 * configure.in (mips host): Accept "ultrix" with version number.
2890 * expr.c (floating_constant): Separate "=-" to avoid confusing
2891 ancient or broken compilers.
2893 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
2894 processor/opcode mismatch, so reword the error message.
2895 (md_assemble): If no CPU has been set (even if FPU/PMMU

3033 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
3035 * Makefile.in (install): Install into $(tooldir)/bin, since that's
3036 where gcc looks for it.

3106 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3108 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3110 * expr.c (operand): if can't work out what sort of operand it is,
3111 then look through FLT_CHARS for a hint.
3113 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3115 * Makefile.in, configure.in: removed traces of namesubdir,

3117 copyrights to '92, changed some from Cygnus to FSF.
3119 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3120 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3121 copyrights to '92, changed some from Cygnus to FSF.
3123 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3125 * expr.c: If an expression is single comma, then return with
3126 SEG_ABSENT rather than an error - since the sparc front end does
3127 really strange things with things like fbge,a
3129 * as.h: include bfd.h if using many sections
3130 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3131 local labels didn't work.
3132 * listing.c (list_symbol_table): don't core dump when there's no
3134 * write.c, write.h: call fix_new with the right number of args on
3136 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3139 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3141 * app.c: MRI compatibility - allow single quote to start a string.
3142 * as.c: fix typo recently introduced.
3143 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3144 * expr.c: Much rewriting, to accomodate MRI syntax for
3145 expressions. Also easier to read now.
3146 * listing.c: Put back defuns
3147 * read.c: modified to accept MRI syntax, put back listing pseudo
3148 ops so that an assembler built with NO_LISTING ignores list ops
3150 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3151 machine is a SPARC or a 29K.
3152 * config/obj-aout.c: added s_sect pseudo op
3153 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3154 fill in the timestamp.
3155 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3156 anymore, define all the relocs which the tc-<x> bit will use so we
3157 can translate from them to the coff types.
3158 * config/tc-a29k.c: reloc_type isn't ane enum any more
3159 * config/tc-m68k.c: Added NO_RELOC definition.
3161 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3163 * Makefile.in: put header files before C source for TAGS; remove
3164 references to non-existent syscalls.h.
3166 * read.c, write.c subsegs.c: back out the .bss changes.
3168 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3170 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3174 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3176 * symbols.c (local_label_name): symbols now start with ^A.
3178 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3179 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3180 generate these sections. .align: will use NOP_OPCODE or 0
3181 for padding. This is just for being nice to the
3184 * expr.c (operand): changed to generate local label "\001L0"
3185 starting with a ^A so that it is recognized as a local label.
3187 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3189 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3190 i/o opcodes - inb, inw, outb and outw. string manipulation with
3191 att syntax - scmp, slod, smov, ssca, ssto.
3193 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3194 to just after .file .
3196 In obj_crawl_symbol_chain() where it tries to put the external
3197 symbols apart, with the condition:
3198 (!S_IS_DEFINED(symbolP) &&
3199 !S_IS_DEBUG(symbolP) &&
3200 !SF_GET_STATICS(symbolP))
3201 it was moving too many symbols out. So I switch it back to the
3203 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3205 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3206 so that we don't use the F_RELFLG which make the linker complain
3207 that somebody has stripped the relocation info.
3209 Also, the AIX ld program require that the relocation table
3210 is sorted by r_vaddr like the standard ATT assembler does.
3212 [he also changed the sizeof(struct ...)'s into the coff
3213 style FOOSZ macros. I'm not sure this is right, but I can't
3214 remember why. xoxorich.]
3216 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3218 * Makefile.in, configure.in, doc: use the doc. Build it, install
3221 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3223 * read.c: white space and comments only.
3225 * configure.in: use the new atof-ns32.c for ns32k.
3227 * write.c: comment change only.
3229 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3230 aren't yet integrated.
3232 * tc-i860.[hc]: blew off the dust. Something must still be done
3233 about conflicting relocation types.
3235 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3238 * tc-i960.c, tc-sparc.c: white space and comments only.
3240 * tc-a29k.h: delete duplicate macro definition.
3242 * new file atof-ns32k.c copied from hack's last unreleased gas.
3244 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3246 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3249 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3250 ChangeLog's prior to this are sketchy at best. I have logs.
3251 They just aren't ChangeLogs.
