2833 stripped down to discard subdir stuff and adapted to give a
2834 non-zero exit status if either file differs.

2927 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2928 it's better to use the one in libiberty.
2930 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2932 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2947 used to be added by coff_add_linesym, removed Oct 7.
2948 (coff_adjust_section_syms): Ignore sections with no seginfo.
2950 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2952 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
2953 "stage" symlink to the appropriate stage* directory, and use it
2954 instead in the -B options.
2955 (comparison): Revert yesterday's change.
2957 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

2970 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2971 running the binary through sed to avoid differences due to
2972 "stage1" or "stage2" having been written into the binary.
2974 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2976 ELF symbol size handling, based on code from Eric Youngdale:
2977 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

2986 (obj_elf_size): Deleted unused code. If size is non-reducible
2987 expression, allocate some storage for the sy_obj field and copy
2989 (elf_frob_symbol): New function. Computes sizes, calls
2990 ecoff_frob_symbol if appropriate.
2992 * write.c (fixup_segment): For i386 elf and coff (for now), don't

3041 (diststuff): New target; builds DISTSTUFF.
3042 (realclean): Separate target, depend on clean and distclean, then
3044 * make-gas.com: Deleted.

3065 referring to PLT entries.
3066 * write.c (fix_new_internal): Initialize fx_plt to zero.
3067 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
3068 Don't adjust fx_offset by frag address, since S_GET_VALUE now
3069 includes the frag address.
3070 (fixup_segment): Changed local var PCREL to type int, added PLT.
3071 If PC-relative fixup refers to a PLT entry for a symbol in the
3072 current section, don't reduce it.

3096 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3098 * configure.in: Set bfd_gas for all sparc targets in one place,
3099 instead of separately for each. Correctly handle user-supplied
3100 "--enable-bfd-gas" option.
3102 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3104 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3107 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3108 processing if add_symbol is undefined or in expr_section.
3109 (resolve_symbol_value, case O_add): For symbol plus
3110 constant-valued symbol, convert to O_symbol and re-reduce.
3111 (S_GET_VALUE): If symbol needs resolving, resolve it.
3112 (indent_level): No longer static.
3113 (print_symbol_value_1): Don't print frag address if it matches

3117 (print_expr_1): Fix whitespace before printing X_add_number.
3119 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3120 not symbol_new, for symbols holding expression values.
3121 * expr.h (make_expr_symbol): Move declaration here.
3122 * write.c (fix_new_exp): Handle O_add by creating an
3123 expression-valued symbol, and calling fix_new_exp recursively.
3124 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3125 undefined symbol and a constant, fold the constant into the fixup,
3126 and refer to the undefined symbol directly. Then process the
3127 fixup again from scratch.
3128 (write_object_file): Before calling adjust_reloc_syms, make a pass
3129 through the symbol list trying to resolve values.
3131 * write.c (print_fixup): New routine, for debugging.
3132 (write_relocs): Call bfd_install_relocation. Deleted various

3148 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3150 * write.c (write_relocs): Add file name and line number to
3151 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3152 RELOC_EXPANSION_POSSIBLE.
3154 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3156 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3157 here. Use them for deciding which PRINTF*LIKE macro definitions

3160 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3161 default definitions matching what we were doing before.
3162 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3163 always use the varargs form if not using stdarg. It's safe to
3164 always use vfprintf, because libiberty will provide it if the
3165 native system doesn't. Also, always make format be const.
3166 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3182 deciding whether to record it.
3183 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
3184 false (if defined) as well as checking for reg_section.
3185 (listing_listing): Iterate fetching lines while line number is too
3186 low, and we haven't run off the end of the input file.
3188 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3190 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

3199 * config/ho-*.h: Now-unused files deleted.
3201 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3202 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3203 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3204 zero. Don't call obj_frob_forward_symbol.
3205 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3206 X_add_number is zero.
3207 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3209 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3211 (strchr): Don't declare.
3212 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
3213 md_estimate_size_before_relax, md_ri_to_chars,
3214 md_create_short_jump, md_create_long_jump.
3215 (brtab_emit): Use data_section, not SEG_DATA.
3217 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3219 * config/vms-conf.h: new file, manually derived from conf.in.
3220 * config-gas.com: use it, and eliminate obsolete "host.h".

3224 * config/tc-ppc.c (ppc_current_block): New static variable.
3225 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

3229 (ppc_es): Clear ppc_current_block.
3230 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3231 from the csect of the enclosing block.
3233 * config/tc-mips.c (insns_since_cache_access): Remove.
3234 (append_insn): Remove setting of insns_since_cache_access, and
3235 special 4600 handling; it turns out not to be required.
3237 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3239 * config/tc-mips.c (md_shortopts): Remove E.
3240 (md_longopts): Add EB and EL.
3241 (md_parse_option): Handle -EB and -EL as separate options, rather
3242 than as a single -E option with an argument.
3244 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
3246 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3247 involving global symbols too.
3249 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3251 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3253 * configure.in: Test for remove, not delete. Fix cross-assembler
3255 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

3259 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3260 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

3263 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3265 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3266 many others): new macros; values obtained from "DSTRECRDS.SDL".
3267 * config/obj-vms.h (various): use them.
3268 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3269 representation (only enum bitfields can avoid being bitstrings).
3270 (bitfield_suffix, setup_basic_type): new routines.
3271 (VMS_typedef_parse): use them. Now recognize bitfields of all
3272 integral types, not just type `int'. Caveat: the representation
3273 used for bitfields still does not work for objects placed in
3274 registers, and gcc's optimizer sometimes puts small structs there.
3276 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3278 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3279 bit from const_flag.
3280 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

3282 and declare the latter.
3283 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3285 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3286 (vms_check_for_special_label): new routine (tc_frob_label).
3287 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3288 and `gcc2_compiled.' labels; they won't reach here any more.
3289 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3290 double', use `vax_g_doubles' flag to select type of double.
3291 (VMS_write_object_file) [traceback setup]: don't pass symbols
3292 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

3300 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3301 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3302 be obsolete; gcc does it automatically for vms target. It's
3303 also misnamed, because it is for the "VAX C" run-time library,
3304 not the newer "DEC C" one which has much different startup code.]
3305 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3306 `S_GET_xxx(symbol) = new_value'.

3329 fixups, store 32bits of unwind information in the fx_addnumber
3331 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3332 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3333 pointer to 32 bits of unwind info.
3334 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3335 pointer to the dummy symbol; set the addend field to fx_addnumber.

3348 to modify the gcc-vms driver when intending to use with gcc 1.x.
3349 * as.c (parse_options): suppress 'v' from std_short_options and
3350 eliminate VMS-specific conditional initialization;

3355 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3356 for O_big literal operands (double floats and long long ints);
3357 [VMS, md_shortopts]: add second colon after 'v';
3358 (md_parse_options) [VMS, case 'v']: check for argument, so

3557 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3558 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3559 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3560 message to try to ease confusion about autoconf's

4291 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
4292 REAL8 and COMPLX8; not used yet, because gcc outputs the same

4307 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4309 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4310 to put a common symbol in a set.

4353 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4355 * read.c (emit_expr): Use memset to zero out memory, rather than
4356 going through md_number_to_chars. This permits handling symbolic

4409 m68040_control_regs, m68060_control_regs): New arrays.
4410 (control_regs): New pointer.
4411 (m68k_ip): Use control_regs instead of testing CPU every time.
4412 Use last_movec_reg too. In error messages, handle 68060, and
4413 print 68060 for mfloat, too.
4414 (m68k_init_after_args): Handle "68060". Use m68040up for making
4415 m68851 choice. Set control_regs.

4784 * config/tc-mips.c (append_insn): Permit branches to be switched
4785 with the preceding instruction even if .set nobopt has been seen.
4786 .set nobopt actually controls whether to bring up an instruction

4927 elf_tc_make_sections stuff. It was there to support PA braindamage
4928 which has been fixed, and in the case of elf_tc_make_sections is
4929 redundant with elf_tc_final_processing.

5032 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5065 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5066 works). Do not permit -G with SVR4_PIC.
5067 (s_abicalls): Warn if -G was used, and force -G 0.
5068 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5117 * write.c (symbol_table_frozen): New variable, to be set after
5118 bfd_set_symtab is called.
5119 (dump_section_relocs): Note whether a symbol is a section symbol
5121 (adjust_reloc_syms): For now, always supply an absolute symbol for
5122 fixups without symbols but not yet `done'. Use section_symbol to
5123 get the symbol, instead of going directly for abs_symbol.
5124 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5125 reloc is not a section symbol and is not in the symbol table.
5126 (set_symtab): New function, broken out from write_object_file.
5127 Counts symbol table instead of relying on an earlier count.
5128 (write_object_file): Call set_symtab, but do it after potentially
5129 invoking the *_frob_file macros. Don't bother counting symbols.
5130 Call symbol_remove, instead of expanding it in place. Moved the
5131 conditionalized `object_file_size' declaration down to
5132 conditionalized block where it's used. When using the absolute
5133 symbol for a fixup without a symbol, set sy_used_in_reloc.
5134 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5135 the correct symbol for the absolute section.
5137 * subsegs.c (section_symbol): Use symbol_new instead of
5138 symbol_make, since we may want it to go into the symbol table.
5139 Make the new symbol have internal linkage. If
5140 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5141 symbol with the newly created GAS symbol.
5142 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

5150 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5151 (sparc_ip, label "immediate"): Reject constants for pcrel
5152 instructions only if the relocation type indicates a "call"
5153 instruction and the offset is within range of a "jmpl %g0". If
5154 it's not in range, use the absolute section symbol plus an offset.
5155 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5157 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5159 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5162 * configure.in: Eliminated all targets using obj-coff but not
5163 defining BFD_ASSEMBLER; I think all such targets that are
5164 supported will be matched by real CPU-OS combinations earlier in
5166 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5167 some comments about the dpx2 configuration, but left it disabled,
5168 since it couldn't be reached before.
5169 (target a29k-amd-ebmonold): Deleted.

5179 the 'j' operand if there are no further alternatives for this
5182 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5183 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5184 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5186 * config/tc-mips.c (mips_align): Take new argument, label, and use
5187 it instead of global insn_label.
5188 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5189 call to mips_emit_delay and pass it to mips_align.
5191 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5193 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

5211 values to reduce number of lookups with S_GET_VALUE. Skip debug
5212 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5213 holger@botbso.rhein-main.de.)
5214 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5215 field. (Also from Holger Teutsch.) Watch for a would-be register
5216 mask that spans frags.
5218 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5219 this_base, not line_base. (Patch from Andreas Arens,

7358 still being worked on. Mark Elf configurations (except sparc and
7359 i386) as developmental. Deleted cases matching some generic names
7360 in favor of more specific names. (E.g., when we get Alpha

7387 are only used within tc-hppa.c static. PARAMize all functions.
7388 Add comments to functions. Delete unused functions, variables,
7389 #defines, etc. Delete unused members within structures. Delete
7390 ldil;ble hacks -- it is believed they were installed to work
7391 around old gas bugs. Avoid using mixed case for local
7392 functions, variables, and structures. Fix formatting problems
7393 not found by GNU-indent. Add FIXME notices for things which
7394 should be worked on the near future. Delete lots of old

8557 * Extensive changes to permit symbols to contain any expression
8558 type and to delay the computation of the expression until the
8559 value is actually needed. This permits setting symbols to values
8560 calculated based on object code size. Expressions were changed to
8561 no longer be in a section, to stop the overloading of segment and
8562 expression type that previously occurred.
8564 * as.c (big_section, pass1_section, diff_section, absent_section):
8566 (expr_section): Added (used for dummy symbols which hold

8650 (previous_section, previous_subsection): New vars.
8651 (obj_elf_section): Save current place in case DWARF code wants us
8652 to pop back to it. Handle unquoted section name as well as quoted
8653 section name. Don't crash on invalid strings.
8654 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
8657 * config/obj-elf.h: Don't include struc-symbol.h.

8675 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
8676 calculating opP->isiz; this permits the expression size to be
8677 determined as well, later on.

8691 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
8693 * read.c (float_cons): Simplified parsing logic. If
8694 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

8714 (macro): Call mips_emit_delays before setting mips_noreorder.
8715 Increment and decrement mips_noreorder rather than using

8742 (omagic): Removed unused variable.
8744 * Preliminary support for m88k-coff.

8763 * Removed sy_forward and replaced it with an undefined expression
8764 as the value of a symbol.
8765 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
8766 sy_resolved and sy_resolving single bit fields.
8767 * symbols.c (symbol_new): Don't initialize sy_forward field.
8768 (resolve_symbol_value): New function to adjust symbol value by
8769 fragment address, using recursion to resolve forward symbols.

8771 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
8772 expression rather than setting symbolP->sy_forward.
8773 * write.c (write_object_file): Use resolve_symbol_value on
8774 symbols, keeping the common case (the old behaviour) inline.

9801 than ECOFF line number information.
9802 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9834 * doc/as.texinfo: First pass at using new texinfo features --
9835 variables, conditional tests. Far from complete.

9881 (srcdir): Delete second, bogus definition.
9882 (as.info): Look for as-*.texinfo in current directory rather than
9886 * doc/configure.in: Create links to all as-*.texinfo files in the
9887 source directory, if that's not the current directory.
9889 * configure.in (per-host): Accept MIPS host with BSD version

9910 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9911 process relocs if there aren't any relocs to process. Avoids
9912 malloc/free bug on SCO too.

9915 avoid some redefinition complaints on some systems.
9916 (const, volatile): Don't need these conditionally defined if we
9917 use CONST and VOLATILE from ansidecl.h.
9918 (seg_name): Use CONST, not const.
9920 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9922 * config/tc-mips.c: Reindented to GNU standards.
9924 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9926 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9927 (fixup_segment): Add a29k special case; the linker is not prepared
9928 to see a segment offset here.
9930 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9931 9 to only keep a space in between identifier characters.
9933 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9935 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9936 srcdir, might be in objdir.
9938 * doc/Makefile.in: dvi depends on as.dvi

9961 * Makefile.in (targ-cpu.o): Depend on config.h.
9963 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9965 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9966 dropping a space immediately following an identifier.
9967 * expr.c, write.c: Rewrote assert expressions to not use multiple
9968 lines; I don't think that can be done portably.
9969 * config/tc-mips.c (macro): Use $AT if target register is zero in
9970 load instruction, which it can be for a floating point load.

9980 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9983 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9984 z8k-opc.h, not z8k.h.
9986 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9989 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9991 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9993 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

10044 prototypes for all static functions. Moved existing minimal
10045 debugging format support info #ifndef OBJ_ECOFF blocks.
10046 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10047 does not support a non sign extended high 16 bits reloc. Adjusted

10094 * make-gas.com: Find obstack.obj if it's not in the current
10096 * read.c (s_ignore): Don't declare is_end_of_line. It's
10097 redundant, and triggers a VMS gcc compiler bug.
10099 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10100 current segment as an argument. (Ignored in all cases but VMS.)
10101 All callers and definitions changed.

10123 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10125 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10128 * configure.in: mips-bsd configuration was missing format spec.
10131 * Makefile.in (Makefile): Depends on configure.in.
10133 * config/tc-mips.c (append_insn): Don't check for alignment of
10134 frag in memory; alignment of instructions in section is a separate

10154 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10155 constants are accepted, but symbolic values are not. GCC will not
10156 generate the latter currently.
10158 * frags.c (frag_init): New function.
10159 (zero_address_frag, bss_address_frag): Now initialized at run

10204 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10205 (fixup_segment): Make sure common-section symbols get treated the
10206 same as undefined symbols.
10207 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

10210 * write.h (fix_new): Update prototype.
10212 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10213 md_section_align, md_undefined_symbol): Don't provide prototypes
10214 if these are defined as macros.
10215 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10237 new section/subsection.
10239 * read.c: Don't include ctype.h.

10411 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10412 md_relax_table): Use default zero initialization.
10413 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10422 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
10423 accidentally changed to use subseg_change where it should have
10426 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10428 * expr.c (operand): If character other than comma or newline is a
10429 logical end-of-line character, use the newline case.
10430 From Eric Youngdale:
10431 (operand): Set X_add_number field for floating-point numbers.
10432 (operand): Treat zero byte as end-of-operand.
10434 * configure.in (per-target): Look for with_bfd_assembler option.
10435 For now, only accept "no", until the merge is done.
10437 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10438 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10439 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10440 * read.c: Finish conversion to S_* macros in the VMS only
10441 parts of the program. Add "const" modifier to hex_value.
10442 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10444 * expr.c: Add "const" modifier to hex_value.
10445 * symbols.c: Finish conversion to S_* macros in the VMS only
10446 parts of the program. Add "const" modifier to
10447 md_[long,short]_jump_size. Remove declaration of const_flag
10448 (which will be declared in obj-vms.h).
10449 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10450 Fix arguments to VMS_write_object_file.
10451 * config-gas.com: New file. Script for VMS systems to set up the
10452 configuration to build gas for VMS, and create config.status.
10453 * make-gas.com: Redone to work with new scheme.
10454 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10456 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10457 will swap bytes if needed on a big endian system. Use throughout
10459 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10460 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10461 types of malformed stabs. Change parsing algorithm so that we are
10462 more certain of having all of the information that we need on hand.
10463 * obj-vms.c (final_forward_reference): New function, used to help
10464 resolve the data types of as many struct elements as possible
10465 when some part of the struct is not fully defined by the compiler.
10466 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10468 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10469 as symbols as well in the object file. Look for external functions

10471 g++ compiler is incapable of doing this.
10472 * tc-vax.c: Add '1' option for backward compatibility with older GCC
10474 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

10479 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10481 * read.c (s_data): Always use "data_section", since it'll map to
10482 SEG_DATA or SEG_E1 if needed.
10483 (s_lcomm): Likewise with bss_section.
10484 (s_fill): Use memset, not bzero.
10486 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10488 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10505 otherwise, use seg_name array.
10506 (seg_name): Declare only if not BFD_ASSEMBLER.
10507 (section_alignment): Declare only if not BFD_ASSEMBLER.
10508 (big_section, reg_section, pass1_section, diff_section,
10509 absent_section, text_section, data_section, bss_section): If
10510 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10511 mapping to segT enum values.
10512 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10513 if these are used or defined, if BFD_ASSEMBLER.
10514 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10515 subseg_new split into two functions.
10516 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10518 * as.h (volatile): Don't define if already defined.
10519 (had_errors, had_warnings): Provide prototypes for ANSI C even if

10522 declare with format attribute for -Wformat checking.
10524 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10526 * app.c, config/tc-*.c: Don't include read.h, since it is already

10530 <mtranle@paris.intellicorp.com>.
10531 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10532 obj_format coffbfd and gas_target i386coff for target.
10533 (i[34]86-*-isc*): New host (uses sysv).
10534 * config/i386aix.mt: Removed (no longer used).
10535 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10536 (MINUS_G): Removed.
10537 (LDFLAGS): Added, defined as -shlib.
10538 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10539 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10540 (DOT_LABEL_PREFIX): Define.
10541 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10542 name rather than L0\001.

10545 * symbols.c, symbols.h (local_bss_counter): Removed.
10546 * write.c (write_object_file): bss no longer uses
10547 local_bss_counter. Pass correct data and bss size to
10548 VMS_write_object_file.
10549 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10550 argument, rather than using local_bss_counter.

10554 (size_section): Restored sanity check.
10555 (do_relocs_for): Base section address on s_paddr rather than
10556 computing it. Adjust a29k R_IHIHALF special case to account for
10557 section paddr (used to require paddr to be zero). If there are no
10558 reclos, set s_relptr to 0. Set relocation size in object_headers.
10559 (fill_section): Always set s_vaddr here, removing
10560 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10561 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10562 Set STYP_INFO for .comment.
10563 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10564 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
10565 (crawl_symbols): Handle 8 character section name correctly. Use
10566 H_{SET,GET}_* macros.
10567 (do_linenos_for): Set lineno size in object_headers.
10568 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10569 set s_vaddr here. If string_byte_count remains 4, set it back to
10570 0, and only write strings out if there are some. Call
10571 fill_section before do_relocs_for and do_linenos_for.
10572 (obj_coff_section): Handle optional quoted second argument giving
10573 section characteristics.
10574 (obj_coff_bss): Added to handle .bss.
10575 (obj_coff_ident): Added to handle .ident (puts string in .comment

10595 (do_scrub_next_char): For \", return " not '.
10596 (symbol_chars): Now const.
10598 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10599 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10601 * config/obj-coff.h: Don't use #elif.
10603 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10604 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10606 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10608 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10626 * Changes to support SCO 3.2v4:
10627 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10628 SEG_BSS, fill with NOP_OPCODE.
10629 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10630 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10631 using ZERO_BASED_SEGMENTS.
10632 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10633 never set segment address for SEG_E2 (.bss) and don't write out
10634 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10635 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10636 definitions, and don't merge tags with non-tags. Check for .bf
10637 rather than just checking whether the second character is b and
10638 the third character is f.
10639 (obj_coff_val): gcc can generate values which we don't handle
10640 correctly; discard information for now, since it only affects the
10641 debugging information.
10642 (tag_find_or_name): Don't insert tags in the symbol table.
10643 (yank_symbols): Don't merge labels.
10644 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10650 relative addends by the segment vaddr.
10651 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10652 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
10653 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

10794 z8000 documentation
10795 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10798 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10800 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10802 * subsegs.h: add extern to segment_info declaration.
10804 * read.h: added extern declarations for comment_chars,
10805 line_comment_chars, and line_separator_chars.
10806 read.c, app.c: removed definitions of comment_chars,
10807 line_comment_chars, and line_separator_chars.

10826 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10827 constant will not fit in an immediate field.
10828 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
10830 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
10832 * obj-coff.c (callj_table): Delete global variable.
10833 (obj_emit_relocations): Define it locally here, and only if
10834 TC_I960 is defined.
10836 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10863 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
10865 * Support for i386-sysv.
10866 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10867 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10868 be used to set them all to zero as was done before.
10869 (fill_section): segment addresses now set in write_object_file.
10870 (fill_section): Don't set STYP_NOLOAD for .bss section.
10871 (fixup_segment): 386 uses strange common symbol format.

10906 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10908 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10909 #elif, since it is not supported by old compilers.
10910 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10911 couple of expressions in tc-m68k.c.
10913 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10915 * read.c (cons): If NO_RELOC is defined, use it.

10921 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10922 local labels to start with a .) and set REGISTER_PREFIX to %.
10923 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10925 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10927 * messages.c: Comment changes.
10929 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
10931 * as.h: Test if __STDC__ is defined only, don't test its value.
10932 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10934 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10936 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10939 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10941 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10942 sections starting from zero, rather than making them consecutive.
10943 This makes subsequent reloc calculations easier, esp if the object
10944 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10945 allocate lcomm in .data rather than in .bss. It seems that some
10946 tools can't cope with a non-zero sized bss before linkage.
10948 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10950 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10951 throughout. That enum no longer means what we thought it meant.
10953 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10954 "-mno-688[58]1" options.
10956 * tc-m68k.c: Added CPU32 support.
10958 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10960 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

10969 * Makefile.in (install): if $(tooldir) exists, install as in
10972 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10974 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10975 .word is < -32768 or > 32767. The -J flag causes the error to be
10976 ignored. This is to catch over-sized switches generated by gcc on
10977 systems which don't support the broken .word hack.
10978 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10979 write.c (fixup_segment): check for signed .word overflow if
10980 WARN_SIGNED_OVERFLOW_WORD.
10982 * write.c (fixup_segment): fixed missing parens in expression
10983 checking for byte or word overflow.
10985 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10986 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10987 WARN_SIGNED_OVERFLOW_WORD.
10989 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10990 expression checking for byte or word overflow.

10999 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11001 * input-scrub.c (input_scrub_push): call input_file_begin, not
11003 messages.c (as_perror): print ": " between the passed in error and
11004 the strerror, like perror does.

11013 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11014 Motorola and MIT syntax; gas can now assemble either type of
11016 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11017 From Steve Chamberlain:
11018 m68kcoff.mt: for m68k COFF.
11019 obj-coffbfd.c: (fixup_mdeps) added
11020 (size_section) removed bad sanity check
11021 (fill_section) added rs_machine_dependent case
11022 (write_object_file) call fixup_mdeps
11023 (fixup_segment) set fx_subsy to 0.
11024 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11026 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11029 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11052 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
11053 tc-i960.c (md_ri_to_chars): Always output bout object file in
11054 little endian byte order (used to use endianness of host).
11056 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11058 * config/tc-m68k.c (init_table): Now const. Always include 68851
11059 data, so that "bc" is available to 68040 cache instructions.
11060 Added "tt0", "tt1", and 68ec030 variants.
11061 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11062 (enum _register): Added TT0, TT1.
11063 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11064 line number correctly in "internal error" messages. Don't print
11065 architecture-mismatch message for operand errors.
11067 From Colin Smith (colin@wrs.com):
11068 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11069 than install_operand.
11071 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11073 * listing.c (buffer_line): rewind to the start of include
11074 files, they might be included twice.
11076 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11078 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11080 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11081 one element of a family.
11083 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11085 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11086 so that we can assemble hand-written libgcc code.
11088 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11090 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11091 has already been formatted (but may still contain %-characters).
11092 (as_bad): Likewise.
11094 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11096 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11097 written with indirection on the last two operands, which can be
11098 either data or address registers. Added a new operand type 'r'
11099 which accepts either register type. Added '(' to notend stuff in
11100 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11102 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11104 * as.h (enum _relax_state): Start off at one, not zero, to better
11105 catch uninitialized-variable errors.
11106 (linkrelax): Declare new variable.
11108 * messages.c (warning_count, error_count): Default initializer is
11111 * write.c: Merged some declarations, using PARMS macro.

11113 data_last_frag): No longer static.
11114 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11115 defined, call it. Change segments before calling fixup_segment.
11116 (relax_align): If linkrelax, provide extra padding.
11118 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11119 their not having symbols associated.
11121 * tc-i960.c (norelax, instrument_branches): Default initializer is
11123 (linkrelax): Delete variable definition.

11212 characteristics have been), default to 68020. Don't need extra
11213 quotes around error string.

11351 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11352 where gcc looks for it.
11354 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11356 * Makefile.in: Changed some lines to be less confusing for some

11396 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11398 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11422 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11424 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11426 * expr.c (operand): if can't work out what sort of operand it is,
11427 then look through FLT_CHARS for a hint.
11429 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11431 * Makefile.in, configure.in: removed traces of namesubdir,
11432 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11433 copyrights to '92, changed some from Cygnus to FSF.
11435 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11436 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11437 copyrights to '92, changed some from Cygnus to FSF.
11439 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11441 * expr.c: If an expression is single comma, then return with
11442 SEG_ABSENT rather than an error - since the sparc front end does
11443 really strange things with things like fbge,a
11445 * as.h: include bfd.h if using many sections
11446 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11447 local labels didn't work.
11448 * listing.c (list_symbol_table): don't core dump when there's no
11450 * write.c, write.h: call fix_new with the right number of args on
11452 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11455 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11457 * app.c: MRI compatibility - allow single quote to start a string.
11458 * as.c: fix typo recently introduced.
11459 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11460 * expr.c: Much rewriting, to accomodate MRI syntax for
11461 expressions. Also easier to read now.
11462 * listing.c: Put back defuns
11463 * read.c: modified to accept MRI syntax, put back listing pseudo
11464 ops so that an assembler built with NO_LISTING ignores list ops
11466 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11467 machine is a SPARC or a 29K.
11468 * config/obj-aout.c: added s_sect pseudo op
11469 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11470 fill in the timestamp.
11471 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11472 anymore, define all the relocs which the tc-<x> bit will use so we
11473 can translate from them to the coff types.
11474 * config/tc-a29k.c: reloc_type isn't ane enum any more
11475 * config/tc-m68k.c: Added NO_RELOC definition.
11477 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11479 * Makefile.in: put header files before C source for TAGS; remove
11480 references to non-existent syscalls.h.
11482 * read.c, write.c subsegs.c: back out the .bss changes.
11484 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11486 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11488 * a.out.h: removed.
11490 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11492 * symbols.c (local_label_name): symbols now start with ^A.
11494 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11495 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11496 generate these sections. .align: will use NOP_OPCODE or 0
11497 for padding. This is just for being nice to the
11500 * expr.c (operand): changed to generate local label "\001L0"
11501 starting with a ^A so that it is recognized as a local label.
11503 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11505 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11506 i/o opcodes - inb, inw, outb and outw. string manipulation with
11507 att syntax - scmp, slod, smov, ssca, ssto.
11509 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11510 to just after .file .
11512 In obj_crawl_symbol_chain() where it tries to put the external
11513 symbols apart, with the condition:
11514 (!S_IS_DEFINED(symbolP) &&
11515 !S_IS_DEBUG(symbolP) &&
11516 !SF_GET_STATICS(symbolP))
11517 it was moving too many symbols out. So I switch it back to the
11519 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11521 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11522 so that we don't use the F_RELFLG which make the linker complain
11523 that somebody has stripped the relocation info.
11525 Also, the AIX ld program require that the relocation table
11526 is sorted by r_vaddr like the standard ATT assembler does.
11528 [he also changed the sizeof(struct ...)'s into the coff
11529 style FOOSZ macros. I'm not sure this is right, but I can't
11530 remember why. xoxorich.]
11532 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11534 * Makefile.in, configure.in, doc: use the doc. Build it, install
11537 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11539 * read.c: white space and comments only.
11541 * configure.in: use the new atof-ns32.c for ns32k.
11543 * write.c: comment change only.
11545 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11546 aren't yet integrated.
11548 * tc-i860.[hc]: blew off the dust. Something must still be done
11549 about conflicting relocation types.
11551 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11554 * tc-i960.c, tc-sparc.c: white space and comments only.
11556 * tc-a29k.h: delete duplicate macro definition.
11558 * new file atof-ns32k.c copied from hack's last unreleased gas.
11560 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11562 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11565 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11566 ChangeLog's prior to this are sketchy at best. I have logs.
11567 They just aren't ChangeLogs.
