2836 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
2837 (tc_gen_reloc): Simplify. It's no longer necessary to set a
2838 reloc's addend field to zero for function symbols.
2839 (md_apply_fix): Simplify. For fixups which will require a SOM
2840 reloc, just clear out the necessary bits in the output file.

2844 * Makefile.in (BISON): Use bison -y, not bison.

2858 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
2860 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2861 it's better to use the one in libiberty.
2863 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2865 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
2866 change; it breaks the rs6000 support, and doesn't seem to be
2869 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
2871 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

2877 rather than explicitly adding the frag address.
2878 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

2880 used to be added by coff_add_linesym, removed Oct 7.
2881 (coff_adjust_section_syms): Ignore sections with no seginfo.
2883 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2885 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
2886 "stage" symlink to the appropriate stage* directory, and use it
2887 instead in the -B options.
2888 (comparison): Revert yesterday's change.
2890 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

2895 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
2897 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
2898 for an embedded PIC switch expression, since the definition of
2899 S_IS_LOCAL was changed.

2903 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2904 running the binary through sed to avoid differences due to
2905 "stage1" or "stage2" having been written into the binary.
2907 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
2909 ELF symbol size handling, based on code from Eric Youngdale:
2910 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
2911 expression pointer to the symbol structure, used for `size'
2912 expressions that couldn't be reduced to constants when initially
2914 (elf_frob_symbol): Declare.

2917 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
2919 (obj_elf_size): Deleted unused code. If size is non-reducible
2920 expression, allocate some storage for the sy_obj field and copy
2922 (elf_frob_symbol): New function. Computes sizes, calls
2923 ecoff_frob_symbol if appropriate.
2925 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2926 add in value of symbol from another defined section of the file.
2928 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

2972 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
2974 (diststuff): New target; builds DISTSTUFF.
2975 (realclean): Separate target, depend on clean and distclean, then
2977 * make-gas.com: Deleted.
2979 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
2980 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
2982 (i386_operand): Don't look up section symbol for
2984 (reloc): Always permit return of 8- and 16-bit relocation types.
2985 Add a space after "pc-relative" in the error message.
2986 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
2987 BFD_RELOC_386_GOTOFF relocs.

2991 (TC_VALIDATE_FIX): New macro -- call it.
2992 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

2997 * write.h (struct fix): Added new bitfield fx_plt, for fixups
2998 referring to PLT entries.
2999 * write.c (fix_new_internal): Initialize fx_plt to zero.
3000 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
3001 Don't adjust fx_offset by frag address, since S_GET_VALUE now
3002 includes the frag address.
3003 (fixup_segment): Changed local var PCREL to type int, added PLT.
3004 If PC-relative fixup refers to a PLT entry for a symbol in the
3005 current section, don't reduce it.

3012 (print_fixup): Added prototype. Show address on first line. Show
3013 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

3027 Show fx_r_type and fx_addsy fields.
3029 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3031 * configure.in: Set bfd_gas for all sparc targets in one place,
3032 instead of separately for each. Correctly handle user-supplied
3033 "--enable-bfd-gas" option.
3035 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3037 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3040 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3041 processing if add_symbol is undefined or in expr_section.

3043 constant-valued symbol, convert to O_symbol and re-reduce.
3044 (S_GET_VALUE): If symbol needs resolving, resolve it.
3045 (indent_level): No longer static.
3046 (print_symbol_value_1): Don't print frag address if it matches
3047 zero_address_frag. Don't print "resolving" if already resolved.

3050 (print_expr_1): Fix whitespace before printing X_add_number.
3052 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3053 not symbol_new, for symbols holding expression values.
3054 * expr.h (make_expr_symbol): Move declaration here.
3055 * write.c (fix_new_exp): Handle O_add by creating an
3056 expression-valued symbol, and calling fix_new_exp recursively.
3057 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3058 undefined symbol and a constant, fold the constant into the fixup,
3059 and refer to the undefined symbol directly. Then process the
3060 fixup again from scratch.
3061 (write_object_file): Before calling adjust_reloc_syms, make a pass
3062 through the symbol list trying to resolve values.
3064 * write.c (print_fixup): New routine, for debugging.
3065 (write_relocs): Call bfd_install_relocation. Deleted various
3066 hacks for working around problems with bfd_perform_relocation.
3068 * Makefile.in (VERSION): Update to 2.4.90.
3070 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3072 * Makefile.in (gasp.o): Depends upon config.h.
3074 * config/tc-mips.c: Include subsegs.h.
3075 (md_apply_fix): If an unconditional b or bal overflows, and we are
3076 not assembling PIC code, replace it with a j or jal.
3078 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
3079 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
3081 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3083 * write.c (write_relocs): Add file name and line number to
3084 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3085 RELOC_EXPANSION_POSSIBLE.
3087 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3089 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3090 here. Use them for deciding which PRINTF*LIKE macro definitions
3092 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
3093 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
3094 default definitions matching what we were doing before.
3095 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3096 always use the varargs form if not using stdarg. It's safe to
3097 always use vfprintf, because libiberty will provide it if the
3098 native system doesn't. Also, always make format be const.
3099 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
3101 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

3114 (listing_newline): Check filename as well as line number when
3115 deciding whether to record it.
3116 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
3117 false (if defined) as well as checking for reg_section.
3118 (listing_listing): Iterate fetching lines while line number is too
3119 low, and we haven't run off the end of the input file.
3121 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3123 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
3125 * ecoff.c (ecoff_generate_asm_lineno): check if
3126 current_stabs_filename is NULL before strcmp.
3127 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
3130 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3132 * config/ho-*.h: Now-unused files deleted.
3134 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3135 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3136 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3137 zero. Don't call obj_frob_forward_symbol.
3138 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3139 X_add_number is zero.
3140 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3142 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3144 (strchr): Don't declare.
3145 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
3146 md_estimate_size_before_relax, md_ri_to_chars,
3147 md_create_short_jump, md_create_long_jump.
3148 (brtab_emit): Use data_section, not SEG_DATA.
3150 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3152 * config/vms-conf.h: new file, manually derived from conf.in.
3153 * config-gas.com: use it, and eliminate obsolete "host.h".

3157 * config/tc-ppc.c (ppc_current_block): New static variable.
3158 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
3159 ppc_current_block. Don't move around any stab symbol, just those
3161 (ppc_bs): Set ppc_current_block.
3162 (ppc_es): Clear ppc_current_block.
3163 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3164 from the csect of the enclosing block.
3166 * config/tc-mips.c (insns_since_cache_access): Remove.
3167 (append_insn): Remove setting of insns_since_cache_access, and
3168 special 4600 handling; it turns out not to be required.
3170 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3172 * config/tc-mips.c (md_shortopts): Remove E.
3173 (md_longopts): Add EB and EL.
3174 (md_parse_option): Handle -EB and -EL as separate options, rather
3175 than as a single -E option with an argument.
3177 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
3179 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3180 involving global symbols too.
3182 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3184 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3186 * configure.in: Test for remove, not delete. Fix cross-assembler
3188 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
3191 * read.c (pseudo_set, case O_symbol): If
3192 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3193 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
3194 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
3196 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3198 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3199 many others): new macros; values obtained from "DSTRECRDS.SDL".
3200 * config/obj-vms.h (various): use them.
3201 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3202 representation (only enum bitfields can avoid being bitstrings).
3203 (bitfield_suffix, setup_basic_type): new routines.
3204 (VMS_typedef_parse): use them. Now recognize bitfields of all
3205 integral types, not just type `int'. Caveat: the representation
3206 used for bitfields still does not work for objects placed in
3207 registers, and gcc's optimizer sometimes puts small structs there.
3209 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3211 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3212 bit from const_flag.
3213 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3214 (tc_frob_label): define this to call vms_check_for_special_label,
3215 and declare the latter.
3216 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3218 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3219 (vms_check_for_special_label): new routine (tc_frob_label).
3220 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3221 and `gcc2_compiled.' labels; they won't reach here any more.
3222 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3223 double', use `vax_g_doubles' flag to select type of double.
3224 (VMS_write_object_file) [traceback setup]: don't pass symbols
3225 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3226 and TBT_Routine_End functions.

3230 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3231 S_GET_VALUE() to avoid many repeated function calls.
3232 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3233 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3234 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3235 be obsolete; gcc does it automatically for vms target. It's
3236 also misnamed, because it is for the "VAX C" run-time library,
3237 not the newer "DEC C" one which has much different startup code.]
3238 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3239 `S_GET_xxx(symbol) = new_value'.
3241 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3243 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
3244 not &bfd_abs_section.
3246 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3248 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
3250 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
3252 * expr.c (expr): Don't reduce the difference of two symbols in the
3253 same frag if the symbols are not in normal sections.
3255 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
3256 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
3257 (obj_attach_unwind_info): Do not define. Not needed anymore.
3258 * config/tc-hppa.c: Delete whitespace at EOL.
3259 (struct hppa_fix_struct): Delete fx_unwind field and all references.
3260 (fix_new_hppa): Last arg is now a pointer to an int. Do not
3261 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
3262 fixups, store 32bits of unwind information in the fx_addnumber
3264 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3265 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3266 pointer to 32 bits of unwind info.
3267 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3268 pointer to the dummy symbol; set the addend field to fx_addnumber.

4224 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
4225 REAL8 and COMPLX8; not used yet, because gcc outputs the same
4226 .stabs for `double' regardless of whether `-mg' is used.
4227 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
4228 for gcc2's predefined types "complex float", "complex double",

4238 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
4240 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4242 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4243 to put a common symbol in a set.

4249 OBJ_BOUT if not BFD_ASSEMBLER.
4250 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
4251 Define as in ../include/aout/aout64.h.

4267 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
4269 * Makefile.in (check): Delete as.new dependency, so that

4286 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4288 * read.c (emit_expr): Use memset to zero out memory, rather than
4289 going through md_number_to_chars. This permits handling symbolic
4290 arguments when the size is larger than sizeof (valueT), if

4342 m68040_control_regs, m68060_control_regs): New arrays.
4343 (control_regs): New pointer.
4344 (m68k_ip): Use control_regs instead of testing CPU every time.
4345 Use last_movec_reg too. In error messages, handle 68060, and
4346 print 68060 for mfloat, too.
4347 (m68k_init_after_args): Handle "68060". Use m68040up for making
4348 m68851 choice. Set control_regs.

4425 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
4426 of 0, because the latter indicates success rather than failure

4673 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
4674 can be used within a label name.
4676 * config/tc-m68k.h (m68k_init_after_args): Declare.
4677 (tc_init_after_args): Define as m68k_init_after_args.
4678 * config/tc-m68k.c (m68k_init_after_args): New function,
4679 containing one-shot code from md_assemble. Added warning for
4680 combination of 68040 and 68851.

4695 and bfd_ecoff_set_regmasks to set the GP value and the register
4696 masks, rather than using the now obsolete fake .reginfo section.

4700 * listing.c (list_symbol_table): Don't print register symbols as
4703 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
4704 underscores, since symbol_new will already have done it.
4705 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
4707 * as.c (main): If tc_init_after_args is defined, invoke it after
4708 all arguments have been processed.
4710 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
4711 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
4712 section instead of .text. Call create_target_segments.

4715 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4717 * config/tc-mips.c (append_insn): Permit branches to be switched
4718 with the preceding instruction even if .set nobopt has been seen.
4719 .set nobopt actually controls whether to bring up an instruction
4720 from the branch target, which gas does not currently support.

4761 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
4762 defaults for defined, private, and spnum fields for the

4778 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4780 * expr.c (operand): Try to parse "0f" and "0b" sequences as
4781 floating point and binary numbers respectively; if it doesn't
4782 work, treat them as local labels.
4784 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
4785 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
4787 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
4789 * vmsconf.sh: In generated file, get ".obj" suffix right, build
4790 source files from other directories into objects in the current
4791 directory, and specify PSECT attributes explicitly to linker.
4792 Also added missing label.
4793 * Makefile.in (stamp-mk.com): Reference new variable
4794 VMS_OTHER_OBJS for list of non-local object files, instead of

4809 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
4810 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
4811 argument, the reloc type.
4812 (load_register): Pass reloc type to macro_build for 'u'.
4813 (macro): Likewise. For M_LA_AB permit a difference expression
4814 when generating embedded PIC code between an arbitrary symbol and
4815 a symbol in the .text section.

4825 * subsegs.c (subsegs_begin): Call memset with args in the correct
4827 (subseg_get): Clear newly allocated seginfo, set its pointer slots
4828 to NULL instead of 0.

4832 * config/tc-hppa.c (pa_procend): Handle case where label was
4833 defined after the .proc directive.

4857 (hppa_tc_symbol): Likewise.
4859 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4860 elf_tc_make_sections stuff. It was there to support PA braindamage
4861 which has been fixed, and in the case of elf_tc_make_sections is
4862 redundant with elf_tc_final_processing.
4864 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4866 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

4876 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
4877 value into the file if the fixup will not generate a reloc.
4879 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
4881 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
4882 don't spew remainder of input file in error message.
4883 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4884 message with reloc type and try to process remainder of file.
4886 * doc/Makefile.in (install-info-as, install-info-gasp): New
4887 targets, now explicitly checking $(srcdir) for info files.
4888 (install-info): Depend on both of them; do nothing more.

4892 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
4894 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4896 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4897 flag rather than signedp field. Only permit extended range if
4898 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4899 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4901 * config/tc-ppc.c (ppc_size): New static variable.
4902 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4903 (md_begin): If an instruction has a size specific flag set, only
4904 add it if we are assembling that size.
4906 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4908 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4909 cross section PC relative relocs right for COFF and ELF.
4911 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4913 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
4914 (OBJ_PROCESS_STAB): Don't define.

4918 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
4919 the type of symbol set symbols which happen to be in the absolute
4920 or undefined section.
4922 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
4924 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
4925 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
4926 and -many (all architectures).
4928 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4930 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
4931 involving a function symbol which is not a plabel to zero.
4932 (md_apply_fix): Never pass a function symbol to field_adjust.
4934 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4936 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
4937 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4939 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4940 branch with an instruction that uses $at, in case the branch is
4942 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4943 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4944 to make it pcrel_offset.
4945 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4946 reloc->address; another gruesome hack to get gas reloc handling to
4949 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4951 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4954 (emit_insn): New function.
4955 (md_assemble): Call it.
4956 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4958 (lituse_pending): New variable. Set by anything that generates a
4959 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4960 tested by code that might want to emit a LITUSE reloc.
4961 (emit_unaligned_io): New function. Currently calls md_assemble,
4962 but it should eventually be converted to generate the insn itself
4963 and call emit_insn directly.
4964 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4965 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4966 emit_bis_r): Likewise.
4967 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4968 (alpha_ip, label get_macro): Don't emit the final instruction if
4970 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4971 unaligned memory access macros.
4972 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
4973 the value can't be resolved.
4975 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4977 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4978 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4979 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
4981 (mips_force_relocation): New function.
4982 (md_apply_fix): Set fixP->fx_done appropriately.

4991 * config/tc-mips.c (enum mips_pic_level): New enum.
4992 (mips_pic): Change from int to enum mips_pic_level. Change all
4993 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4994 (load_address): Handle EMBEDDED_PIC.
4995 (macro): Handle EMBEDDED_PIC in all PIC cases.
4996 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4997 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4998 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4999 works). Do not permit -G with SVR4_PIC.
5000 (s_abicalls): Warn if -G was used, and force -G 0.
5001 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
5002 anything but a.out, not just for ELF. For ECOFF, don't generate a
5003 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
5005 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
5007 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5009 * config/tc-hppa.c (create_new_space): Use ints, not chars as
5010 parameters to avoid losing when compiling with HP CC.
5011 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
5013 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5015 * Makefile.in (config-stamp): If `defs' is defined, emit a
5016 preprocessor directive to create a macro named by this value into
5017 config.new; don't explicitly go for BFD_ASSEMBLER.
5018 * configure.in: Define `defs', not `BFDDEF'. Set it to
5019 MANY_SEGMENTS for any obj-coffbfd target.
5020 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
5021 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
5023 (LOCAL_LOADLIBES): Deleted.
5024 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
5025 * config/m88kcoff.mt (TDEFINES): Ditto.
5026 * config/ebmon29k.mt: Deleted.
5027 * config/h8300hds.mt: Deleted.
5028 * config/ic960coff.mt: Deleted.
5029 * config/sparc.mt: Deleted.
5030 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5031 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5032 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
5033 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

5048 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5050 * write.c (symbol_table_frozen): New variable, to be set after
5051 bfd_set_symtab is called.
5052 (dump_section_relocs): Note whether a symbol is a section symbol
5054 (adjust_reloc_syms): For now, always supply an absolute symbol for
5055 fixups without symbols but not yet `done'. Use section_symbol to
5056 get the symbol, instead of going directly for abs_symbol.
5057 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5058 reloc is not a section symbol and is not in the symbol table.
5059 (set_symtab): New function, broken out from write_object_file.
5060 Counts symbol table instead of relying on an earlier count.
5061 (write_object_file): Call set_symtab, but do it after potentially
5062 invoking the *_frob_file macros. Don't bother counting symbols.
5063 Call symbol_remove, instead of expanding it in place. Moved the
5064 conditionalized `object_file_size' declaration down to
5065 conditionalized block where it's used. When using the absolute
5066 symbol for a fixup without a symbol, set sy_used_in_reloc.
5067 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5068 the correct symbol for the absolute section.
5070 * subsegs.c (section_symbol): Use symbol_new instead of
5071 symbol_make, since we may want it to go into the symbol table.
5072 Make the new symbol have internal linkage. If
5073 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5074 symbol with the newly created GAS symbol.
5075 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
5076 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
5078 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
5080 * config/tc-sparc.c: Include subsegs.h.
5081 (in_signed_range): New function.
5083 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5084 (sparc_ip, label "immediate"): Reject constants for pcrel
5085 instructions only if the relocation type indicates a "call"
5086 instruction and the offset is within range of a "jmpl %g0". If
5087 it's not in range, use the absolute section symbol plus an offset.
5088 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5090 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5092 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5095 * configure.in: Eliminated all targets using obj-coff but not
5096 defining BFD_ASSEMBLER; I think all such targets that are
5097 supported will be matched by real CPU-OS combinations earlier in
5099 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5100 some comments about the dpx2 configuration, but left it disabled,
5101 since it couldn't be reached before.
5102 (target a29k-amd-ebmonold): Deleted.
5104 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5106 * config/tc-hppa.c (pa_import): Correctly handle importing of an
5107 already defined symbol.

6948 BFD_RELOC_MIPS_GPREL. Added new case a.
6949 (set_at, load_register, macro): Changed calls to macro_build to
6950 pass new argument for i, j and o cases.
6951 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
6952 special handling when generating SVR4 PIC code.

7284 OPTIONAL_REGISTER_PREFIX if either is already defined.
7286 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
7288 * configure.in: Set bfd_gas for all sparc targets. Added facility
7289 for keeping or rejecting configurations still under development;
7290 default is to assume production environment, and reject configs
7291 still being worked on. Mark Elf configurations (except sparc and
7292 i386) as developmental. Deleted cases matching some generic names
7293 in favor of more specific names. (E.g., when we get Alpha

7310 through inclusion of tc-hppa.h. Delete all forward declarations
7311 for functions only used within tc-hppa.c, likewise for structures,
7312 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7313 conditional code in a few small places.
7315 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7316 structures, global variables, forward declarations together.

7318 conditional code -- try to group conditional code together
7319 into a few places. Make all functions and variables which
7320 are only used within tc-hppa.c static. PARAMize all functions.
7321 Add comments to functions. Delete unused functions, variables,
7322 #defines, etc. Delete unused members within structures. Delete
7323 ldil;ble hacks -- it is believed they were installed to work
7324 around old gas bugs. Avoid using mixed case for local
7325 functions, variables, and structures. Fix formatting problems
7326 not found by GNU-indent. Add FIXME notices for things which
7327 should be worked on the near future. Delete lots of old
7328 useless (1.36 PA-SOM) code.

7407 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
7409 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
7410 ELF, since the ELF object format does not have these type of
7411 relocations. Change the abort into as as_bad and return
7412 BFD_RELOC_NONE to silence compiler warnings.
7413 (md_assemble): Keep track of the instruction size. Allow white
7414 space between the $ and the constant for compatibility with older
7415 gases and other assemblers.

8490 * Extensive changes to permit symbols to contain any expression
8491 type and to delay the computation of the expression until the
8492 value is actually needed. This permits setting symbols to values
8493 calculated based on object code size. Expressions were changed to
8494 no longer be in a section, to stop the overloading of segment and
8495 expression type that previously occurred.
8497 * as.c (big_section, pass1_section, diff_section, absent_section):

9762 references don't appear to work right.
9764 * as.h (const, volatile): Put these definitions back, and use
9767 * doc/as.texinfo: First pass at using new texinfo features --
9768 variables, conditional tests. Far from complete.
9770 Mon Mar 29 16:05:40 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9772 * read.c: Temporary hack to handle some 64-bit constants. This
9773 should be redone later.

9794 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
9795 the bottom (make expands variables in dependencies when the
9796 dependencies are read, not when they are used).
9798 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
9799 a29k .bss section; the mondfe program doesn't like it.

9814 (srcdir): Delete second, bogus definition.
9815 (as.info): Look for as-*.texinfo in current directory rather than
9819 * doc/configure.in: Create links to all as-*.texinfo files in the
9820 source directory, if that's not the current directory.
9822 * configure.in (per-host): Accept MIPS host with BSD version

9843 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9844 process relocs if there aren't any relocs to process. Avoids
9845 malloc/free bug on SCO too.
9847 * as.h: Move local include files below system include files, to
9848 avoid some redefinition complaints on some systems.
9849 (const, volatile): Don't need these conditionally defined if we
9850 use CONST and VOLATILE from ansidecl.h.
9851 (seg_name): Use CONST, not const.
9853 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9855 * config/tc-mips.c: Reindented to GNU standards.
9857 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9859 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9860 (fixup_segment): Add a29k special case; the linker is not prepared
9861 to see a segment offset here.
9863 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9864 9 to only keep a space in between identifier characters.
9866 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9868 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9869 srcdir, might be in objdir.
9871 * doc/Makefile.in: dvi depends on as.dvi

9889 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9890 bignums, but don't emit error message.
9892 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9894 * Makefile.in (targ-cpu.o): Depend on config.h.
9896 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9898 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9899 dropping a space immediately following an identifier.
9900 * expr.c, write.c: Rewrote assert expressions to not use multiple
9901 lines; I don't think that can be done portably.
9902 * config/tc-mips.c (macro): Use $AT if target register is zero in
9903 load instruction, which it can be for a floating point load.
9905 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
9907 * write.c (write_contents): Compute the relocs before writing out

9913 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9916 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9917 z8k-opc.h, not z8k.h.
9919 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9922 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9924 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9926 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9928 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
9929 to be on a single line.

9951 (main): Call strdup instead.
9953 * configure.in: Handle all 68300 series chips.
9954 * config/tc-m68k.c: Include config.h.

9973 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9974 (struct loc, struct proc, struct file): Moved to tc-mips.c within
9975 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
9976 * config/tc-mips.c: Rearranged for ECOFF support. Added
9977 prototypes for all static functions. Moved existing minimal
9978 debugging format support info #ifndef OBJ_ECOFF blocks.
9979 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9980 does not support a non sign extended high 16 bits reloc. Adjusted
9981 all callers accordingly.
9982 (tc_get_register): Renamed from get_register, and made non-static.
9984 * config/mips-big.mt, config/mips-lit.mt: New files. Define

10024 Wed Mar 3 10:41:46 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10026 Patches from Eric Youngdale:
10027 * make-gas.com: Find obstack.obj if it's not in the current
10029 * read.c (s_ignore): Don't declare is_end_of_line. It's
10030 redundant, and triggers a VMS gcc compiler bug.
10032 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10033 current segment as an argument. (Ignored in all cases but VMS.)
10034 All callers and definitions changed.
10036 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10038 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10050 (obj_elf_xstab): New routine.
10051 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
10052 argument to s_ignore. Put "#if 0" around unused code.
10053 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10054 Call elf_xstabs for .stabs and .xstabs operators.
10056 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10058 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10061 * configure.in: mips-bsd configuration was missing format spec.
10064 * Makefile.in (Makefile): Depends on configure.in.
10066 * config/tc-mips.c (append_insn): Don't check for alignment of
10067 frag in memory; alignment of instructions in section is a separate

10087 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10088 constants are accepted, but symbolic values are not. GCC will not
10089 generate the latter currently.
10091 * frags.c (frag_init): New function.
10092 (zero_address_frag, bss_address_frag): Now initialized at run

10137 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10138 (fixup_segment): Make sure common-section symbols get treated the
10139 same as undefined symbols.

10145 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10146 md_section_align, md_undefined_symbol): Don't provide prototypes
10147 if these are defined as macros.
10148 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10170 new section/subsection.
10172 * read.c: Don't include ctype.h.
10173 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
10174 for now; should be machine-dependent.
10176 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
10177 targets, forcing BFD use.

10181 * config/tc-sparc.c: Use PARAMS macro for static function
10182 declarations. Use BFD_RELOC_ macros everywhere, with

10193 * config/obj-aout.c (obj_aout_stab): Refer to undefined_section,
10194 not SEG_UNKNOWN. Use S_SET_TYPE, S_GET_TYPE, S_GET_DESC instead
10195 of referencing fields directly.
10197 * write.c (cvt_frag_to_fill): New function; extracted from
10199 (write_object_file) [! BFD_ASSEMBLER]: Call it.

10344 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10345 md_relax_table): Use default zero initialization.
10346 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10356 accidentally changed to use subseg_change where it should have
10359 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10361 * expr.c (operand): If character other than comma or newline is a
10362 logical end-of-line character, use the newline case.
10363 From Eric Youngdale:
10364 (operand): Set X_add_number field for floating-point numbers.
10365 (operand): Treat zero byte as end-of-operand.
10367 * configure.in (per-target): Look for with_bfd_assembler option.
10368 For now, only accept "no", until the merge is done.
10370 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10371 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10372 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10373 * read.c: Finish conversion to S_* macros in the VMS only
10374 parts of the program. Add "const" modifier to hex_value.
10375 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10377 * expr.c: Add "const" modifier to hex_value.
10378 * symbols.c: Finish conversion to S_* macros in the VMS only
10379 parts of the program. Add "const" modifier to
10380 md_[long,short]_jump_size. Remove declaration of const_flag
10381 (which will be declared in obj-vms.h).
10382 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10383 Fix arguments to VMS_write_object_file.
10384 * config-gas.com: New file. Script for VMS systems to set up the
10385 configuration to build gas for VMS, and create config.status.
10386 * make-gas.com: Redone to work with new scheme.
10387 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10389 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10390 will swap bytes if needed on a big endian system. Use throughout
10392 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10393 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10394 types of malformed stabs. Change parsing algorithm so that we are
10395 more certain of having all of the information that we need on hand.
10396 * obj-vms.c (final_forward_reference): New function, used to help
10397 resolve the data types of as many struct elements as possible
10398 when some part of the struct is not fully defined by the compiler.
10399 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10401 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10402 as symbols as well in the object file. Look for external functions

10412 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10414 * read.c (s_data): Always use "data_section", since it'll map to
10415 SEG_DATA or SEG_E1 if needed.
10416 (s_lcomm): Likewise with bss_section.
10417 (s_fill): Use memset, not bzero.
10419 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10421 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10438 otherwise, use seg_name array.
10439 (seg_name): Declare only if not BFD_ASSEMBLER.
10440 (section_alignment): Declare only if not BFD_ASSEMBLER.
10441 (big_section, reg_section, pass1_section, diff_section,
10442 absent_section, text_section, data_section, bss_section): If
10443 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10444 mapping to segT enum values.
10445 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10446 if these are used or defined, if BFD_ASSEMBLER.
10447 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10448 subseg_new split into two functions.
10449 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10451 * as.h (volatile): Don't define if already defined.
10452 (had_errors, had_warnings): Provide prototypes for ANSI C even if

10455 declare with format attribute for -Wformat checking.
10457 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10459 * app.c, config/tc-*.c: Don't include read.h, since it is already
10462 * These are based on patches from Minh Tran-le
10463 <mtranle@paris.intellicorp.com>.
10464 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10465 obj_format coffbfd and gas_target i386coff for target.
10466 (i[34]86-*-isc*): New host (uses sysv).
10467 * config/i386aix.mt: Removed (no longer used).
10468 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10469 (MINUS_G): Removed.
10470 (LDFLAGS): Added, defined as -shlib.
10471 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10472 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10473 (DOT_LABEL_PREFIX): Define.
10474 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10475 name rather than L0\001.

10478 * symbols.c, symbols.h (local_bss_counter): Removed.
10479 * write.c (write_object_file): bss no longer uses
10480 local_bss_counter. Pass correct data and bss size to
10481 VMS_write_object_file.
10482 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10483 argument, rather than using local_bss_counter.

10487 (size_section): Restored sanity check.
10488 (do_relocs_for): Base section address on s_paddr rather than
10489 computing it. Adjust a29k R_IHIHALF special case to account for
10490 section paddr (used to require paddr to be zero). If there are no
10491 reclos, set s_relptr to 0. Set relocation size in object_headers.
10492 (fill_section): Always set s_vaddr here, removing
10493 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10494 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10495 Set STYP_INFO for .comment.
10496 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10497 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10501 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10502 set s_vaddr here. If string_byte_count remains 4, set it back to
10503 0, and only write strings out if there are some. Call
10504 fill_section before do_relocs_for and do_linenos_for.
10505 (obj_coff_section): Handle optional quoted second argument giving
10506 section characteristics.
10507 (obj_coff_bss): Added to handle .bss.
10508 (obj_coff_ident): Added to handle .ident (puts string in .comment

10528 (do_scrub_next_char): For \", return " not '.
10529 (symbol_chars): Now const.
10531 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10532 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10534 * config/obj-coff.h: Don't use #elif.
10536 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10537 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10539 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10541 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10562 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10563 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10564 using ZERO_BASED_SEGMENTS.
10565 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10566 never set segment address for SEG_E2 (.bss) and don't write out
10567 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10568 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10569 definitions, and don't merge tags with non-tags. Check for .bf
10570 rather than just checking whether the second character is b and
10571 the third character is f.
10572 (obj_coff_val): gcc can generate values which we don't handle
10573 correctly; discard information for now, since it only affects the
10574 debugging information.

10576 (yank_symbols): Don't merge labels.
10577 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10632 options. Updated options documentation for m68k. Some minor
10633 wording/punctuation changes.

10691 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
10694 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
10696 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;
10697 don't initialize it with NULL.
10699 * config/ho-vax.h (M_VAX): Deleted; was unused.
10701 * README-vms, config/ho-vms.h, config/obj-vms.c, config/obj-vms.h:
10702 New files imported from FSF version, contributed by Eric Youngdale.
10703 * README-vms-dbg, config/vms: Deleted.
10705 * ChangeLog, config/ChangeLog: Merged.

10711 [USG] (setbuffer): Deleted macro.
10713 Mon Nov 23 11:00:16 1992 Ken Raeburn (raeburn@cygnus.com)
10715 * all files: Whitespace changes for GNU indentation style, done by
10716 GNU `indent'. Some cleanup still needed, especially of comments.
10718 * configure.in: No te-386bsd.h file exists; don't try to use it.
10720 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
10722 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
10723 could be doing emulation.
10725 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10727 z8000 documentation
10728 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10731 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10733 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10735 * subsegs.h: add extern to segment_info declaration.
10737 * read.h: added extern declarations for comment_chars,
10738 line_comment_chars, and line_separator_chars.
10739 read.c, app.c: removed definitions of comment_chars,
10740 line_comment_chars, and line_separator_chars.
10742 * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
10743 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
10745 (insert_reg): put REGISTER_PREFIX before register names before
10746 putting them in the symbol table.
10747 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

10755 consistently const, and always initialized them. Included read.h.
10757 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10759 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10760 constant will not fit in an immediate field.
10761 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
10763 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
10765 * obj-coff.c (callj_table): Delete global variable.
10766 (obj_emit_relocations): Define it locally here, and only if
10767 TC_I960 is defined.
10769 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
10770 (m68k_ip): Don't warn about bignum used as float bit-pattern.
10772 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
10773 with a single set using PARAMS macro.
10775 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
10778 * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
10780 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
10781 so widening works consistently.
10783 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
10785 * version.c: Put conditional "const" before version_string, not
10786 before dummy function for VMS. Now version 1.91.03.
10788 * app.c (do_scrub_next_char): Need double-\ before `000' to show
10789 printed rep of null character.
10791 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
10793 * obj-coffbfd.c (write_object_file): check return value of
10794 bfd_close_all_done.
10796 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
10798 * Support for i386-sysv.
10799 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10800 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10801 be used to set them all to zero as was done before.
10802 (fill_section): segment addresses now set in write_object_file.
10803 (fill_section): Don't set STYP_NOLOAD for .bss section.
10804 (fixup_segment): 386 uses strange common symbol format.
10805 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
10806 compatibility with SVR3.2 linker.
10807 * configure.in: i386-sysv and i386-sco use coffbfd.
10809 * app.c (do_scrub_next_char): discard whitespace after a label.
10811 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

10814 hosts, use the sysv configuration for solaris2
10816 Mon Oct 5 09:28:57 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10818 fix i960+non-bfd coff bit rot.
10819 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
10820 support for C source listings. (obj_coff_endef): look in the right
10821 part of the symbol for the symbol name
10823 * tc-m68k.c (get_num): make it work for all segments, not just the
10826 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
10828 * configure.in: recognize i386-*-bsd emulation.
10830 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
10832 * configure.in: use the cpu-vendor-os triple for host and target
10834 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10836 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
10837 * tc-z8k.c: lots of bug fixes
10839 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10841 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10842 #elif, since it is not supported by old compilers.
10843 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10844 couple of expressions in tc-m68k.c.
10846 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10848 * read.c (cons): If NO_RELOC is defined, use it.
10850 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
10852 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
10854 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10855 local labels to start with a .) and set REGISTER_PREFIX to %.
10856 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10858 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10860 * messages.c: Comment changes.
10862 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
10864 * as.h: Test if __STDC__ is defined only, don't test its value.
10865 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10867 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10869 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10872 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10874 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10875 sections starting from zero, rather than making them consecutive.
10876 This makes subsequent reloc calculations easier, esp if the object
10877 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10878 allocate lcomm in .data rather than in .bss. It seems that some
10879 tools can't cope with a non-zero sized bss before linkage.
10881 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10883 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10884 throughout. That enum no longer means what we thought it meant.
10886 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10887 "-mno-688[58]1" options.
10889 * tc-m68k.c: Added CPU32 support.
10891 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10893 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
10895 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10897 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
10898 Change LIBDEPS dependence to LIBS.
10900 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
10902 * Makefile.in (install): if $(tooldir) exists, install as in
10905 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10907 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10908 .word is < -32768 or > 32767. The -J flag causes the error to be
10909 ignored. This is to catch over-sized switches generated by gcc on
10910 systems which don't support the broken .word hack.
10911 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10912 write.c (fixup_segment): check for signed .word overflow if
10913 WARN_SIGNED_OVERFLOW_WORD.
10915 * write.c (fixup_segment): fixed missing parens in expression
10916 checking for byte or word overflow.
10918 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10919 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10920 WARN_SIGNED_OVERFLOW_WORD.
10922 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10923 expression checking for byte or word overflow.
10925 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10927 Support for i386 coff
10928 * obj-coffbfd.h : added stuff
10929 * tc-i386.c (tc_coff_fix2rtype): new function
10930 * tc-i386.h : new coff defines
10932 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10934 * input-scrub.c (input_scrub_push): call input_file_begin, not
10936 messages.c (as_perror): print ": " between the passed in error and
10937 the strerror, like perror does.
10939 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
10941 * Makefile.in: use gas_target instead of modifying target_cpu.
10942 From Steve Chamberlain:
10943 Makefile.in: Handle m68*-*-coff*.
10944 read.c, read.h: add mult argument to s_space
10946 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10947 Motorola and MIT syntax; gas can now assemble either type of
10949 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10950 From Steve Chamberlain:
10951 m68kcoff.mt: for m68k COFF.
10952 obj-coffbfd.c: (fixup_mdeps) added
10953 (size_section) removed bad sanity check
10954 (fill_section) added rs_machine_dependent case
10955 (write_object_file) call fixup_mdeps
10956 (fixup_segment) set fx_subsy to 0.
10957 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10959 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10962 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10964 * Makefile.in (LIBS): Include opcode library.
10966 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
10968 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
10969 including zero are accepted, pass +0.0.
10971 Sun Aug 30 21:24:46 1992 Ian Lance Taylor (ian@cygnus.com)
10973 * Makefile.in: map "as" through program_transform_name when
10976 * doc/Makefile.in: map "as" through program_transform_name when
10979 Sat Aug 29 12:11:12 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
10981 * Makefile.in (as.new): Depend on LOCAL_LOADLIBES.
10983 Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com)
10985 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10986 tc-i960.c (md_ri_to_chars): Always output bout object file in
10987 little endian byte order (used to use endianness of host).
10989 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10991 * config/tc-m68k.c (init_table): Now const. Always include 68851
10992 data, so that "bc" is available to 68040 cache instructions.
10993 Added "tt0", "tt1", and 68ec030 variants.
10994 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10995 (enum _register): Added TT0, TT1.
10996 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10997 line number correctly in "internal error" messages. Don't print
10998 architecture-mismatch message for operand errors.
11000 From Colin Smith (colin@wrs.com):
11001 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11002 than install_operand.
11004 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11006 * listing.c (buffer_line): rewind to the start of include
11007 files, they might be included twice.
11009 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11011 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11013 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11014 one element of a family.
11016 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11018 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11019 so that we can assemble hand-written libgcc code.
11021 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11023 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11024 has already been formatted (but may still contain %-characters).
11025 (as_bad): Likewise.
11027 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11029 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11030 written with indirection on the last two operands, which can be
11031 either data or address registers. Added a new operand type 'r'
11032 which accepts either register type. Added '(' to notend stuff in
11033 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11035 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11037 * as.h (enum _relax_state): Start off at one, not zero, to better
11038 catch uninitialized-variable errors.
11039 (linkrelax): Declare new variable.
11041 * messages.c (warning_count, error_count): Default initializer is
11044 * write.c: Merged some declarations, using PARMS macro.

11046 data_last_frag): No longer static.
11047 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11048 defined, call it. Change segments before calling fixup_segment.
11049 (relax_align): If linkrelax, provide extra padding.
11051 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11052 their not having symbols associated.
11054 * tc-i960.c (norelax, instrument_branches): Default initializer is
11056 (linkrelax): Delete variable definition.
11057 (mem_fmt): Call fix_new with NO_RELOC.

11071 * Makefile.in: always create installation directories. Removed
11072 MINUS_G, set CFLAGS to default to -g, added FLAGS_TO_PASS, passed
11073 FLAGS_TO_PASS to recursive makes.
11075 * doc/Makefile.in: always create installation directories.
11077 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11079 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
11080 being used with args swapped, causing occasional lossage when
11081 refilling buffers after an include file.
11083 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
11085 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
11086 version. Discard bogus DONTDEF version.
11087 (as_warn, as_bad, as_fatal): Likewise.
11089 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
11091 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
11092 selected architecture, print a message saying so and listing what
11093 processors support it, rather than saying "operands mismatch".
11095 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
11097 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

11105 * sparc.mt: New file.
11107 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
11109 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
11110 if TN_SUN3; otherwise align to 2**N-byte bounary.
11112 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11114 * read.c (s_fill): make the .fill size clamped error a warn and
11115 fix bug where 0's were always placed.
11117 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
11118 two bytes of any constant with 0xff:
11120 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11122 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
11123 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
11125 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
11127 * tc-m68k.c (try_index): Error if index scaling specified and
11128 assembling for an older CPU than a 68020.
11130 Sat Aug 1 19:10:13 1992 Ken Raeburn (raeburn@cygnus.com)
11132 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
11133 fx_offset into account.
11135 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
11137 * configure.in (mips host): Accept "ultrix" with version number.
11139 * expr.c (floating_constant): Separate "=-" to avoid confusing
11140 ancient or broken compilers.
11142 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
11143 processor/opcode mismatch, so reword the error message.
11144 (md_assemble): If no CPU has been set (even if FPU/PMMU
11145 characteristics have been), default to 68020. Don't need extra
11146 quotes around error string.
11148 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11150 * read.c (potable): Revert sac's incorrect change made Jul 13.
11151 Align really is supposed to be ptwo not nbytes.

11355 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11357 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11359 * expr.c (operand): if can't work out what sort of operand it is,
11360 then look through FLT_CHARS for a hint.
11362 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11364 * Makefile.in, configure.in: removed traces of namesubdir,
11365 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11366 copyrights to '92, changed some from Cygnus to FSF.
11368 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11369 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11370 copyrights to '92, changed some from Cygnus to FSF.
11372 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11374 * expr.c: If an expression is single comma, then return with
11375 SEG_ABSENT rather than an error - since the sparc front end does
11376 really strange things with things like fbge,a
11378 * as.h: include bfd.h if using many sections
11379 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11380 local labels didn't work.
11381 * listing.c (list_symbol_table): don't core dump when there's no
11383 * write.c, write.h: call fix_new with the right number of args on
11385 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11388 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11390 * app.c: MRI compatibility - allow single quote to start a string.
11391 * as.c: fix typo recently introduced.
11392 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11393 * expr.c: Much rewriting, to accomodate MRI syntax for
11394 expressions. Also easier to read now.
11395 * listing.c: Put back defuns
11396 * read.c: modified to accept MRI syntax, put back listing pseudo
11397 ops so that an assembler built with NO_LISTING ignores list ops
11399 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11400 machine is a SPARC or a 29K.
11401 * config/obj-aout.c: added s_sect pseudo op
11402 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11403 fill in the timestamp.
11404 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11405 anymore, define all the relocs which the tc-<x> bit will use so we
11406 can translate from them to the coff types.
11407 * config/tc-a29k.c: reloc_type isn't ane enum any more
11408 * config/tc-m68k.c: Added NO_RELOC definition.
11410 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11412 * Makefile.in: put header files before C source for TAGS; remove
11413 references to non-existent syscalls.h.
11415 * read.c, write.c subsegs.c: back out the .bss changes.
11417 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11419 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11421 * a.out.h: removed.
11423 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11425 * symbols.c (local_label_name): symbols now start with ^A.
11427 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11428 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11429 generate these sections. .align: will use NOP_OPCODE or 0
11430 for padding. This is just for being nice to the
11433 * expr.c (operand): changed to generate local label "\001L0"
11434 starting with a ^A so that it is recognized as a local label.
11436 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11438 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11439 i/o opcodes - inb, inw, outb and outw. string manipulation with
11440 att syntax - scmp, slod, smov, ssca, ssto.
11442 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11443 to just after .file .
11445 In obj_crawl_symbol_chain() where it tries to put the external
11446 symbols apart, with the condition:
11447 (!S_IS_DEFINED(symbolP) &&
11448 !S_IS_DEBUG(symbolP) &&
11449 !SF_GET_STATICS(symbolP))
11450 it was moving too many symbols out. So I switch it back to the
11452 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11454 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11455 so that we don't use the F_RELFLG which make the linker complain
11456 that somebody has stripped the relocation info.
11458 Also, the AIX ld program require that the relocation table
11459 is sorted by r_vaddr like the standard ATT assembler does.
11461 [he also changed the sizeof(struct ...)'s into the coff
11462 style FOOSZ macros. I'm not sure this is right, but I can't
11463 remember why. xoxorich.]
11465 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11467 * Makefile.in, configure.in, doc: use the doc. Build it, install
11470 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11472 * read.c: white space and comments only.
11474 * configure.in: use the new atof-ns32.c for ns32k.
11476 * write.c: comment change only.
11478 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11479 aren't yet integrated.
11481 * tc-i860.[hc]: blew off the dust. Something must still be done
11482 about conflicting relocation types.
11484 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11487 * tc-i960.c, tc-sparc.c: white space and comments only.
11489 * tc-a29k.h: delete duplicate macro definition.
11491 * new file atof-ns32k.c copied from hack's last unreleased gas.
11493 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11495 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11498 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11499 ChangeLog's prior to this are sketchy at best. I have logs.
11500 They just aren't ChangeLogs.
