2845 referring to PLT entries.
2846 * write.c (fix_new_internal): Initialize fx_plt to zero.
2847 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
2848 Don't adjust fx_offset by frag address, since S_GET_VALUE now
2849 includes the frag address.
2850 (fixup_segment): Changed local var PCREL to type int, added PLT.
2851 If PC-relative fixup refers to a PLT entry for a symbol in the
2852 current section, don't reduce it.
2854 * write.c (adjust_reloc_syms): Exit loop through a label. If
2855 DEBUG5 is defined, print out each fixup before and after
2857 (fixup_segment): If DEBUG5 is defined, print out each fixup before
2858 and after processing.
2859 (print_fixup): Added prototype. Show address on first line. Show
2860 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
2861 NEED_FX_R_TYPE is defined.
2863 * symbols.c (print_symbol_value_1): Check S_IS_LOCAL, S_IS_EXTERN,
2864 S_IS_DEBUG, S_IS_DEFINED also.

2874 Show fx_r_type and fx_addsy fields.
2876 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2878 * configure.in: Set bfd_gas for all sparc targets in one place,
2879 instead of separately for each. Correctly handle user-supplied
2880 "--enable-bfd-gas" option.
2882 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2884 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

2888 processing if add_symbol is undefined or in expr_section.
2889 (resolve_symbol_value, case O_add): For symbol plus
2890 constant-valued symbol, convert to O_symbol and re-reduce.

2892 (indent_level): No longer static.
2893 (print_symbol_value_1): Don't print frag address if it matches
2894 zero_address_frag. Don't print "resolving" if already resolved.

2897 (print_expr_1): Fix whitespace before printing X_add_number.
2899 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2900 not symbol_new, for symbols holding expression values.
2901 * expr.h (make_expr_symbol): Move declaration here.
2902 * write.c (fix_new_exp): Handle O_add by creating an
2903 expression-valued symbol, and calling fix_new_exp recursively.
2904 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2905 undefined symbol and a constant, fold the constant into the fixup,
2906 and refer to the undefined symbol directly. Then process the
2907 fixup again from scratch.
2908 (write_object_file): Before calling adjust_reloc_syms, make a pass
2909 through the symbol list trying to resolve values.
2911 * write.c (print_fixup): New routine, for debugging.
2912 (write_relocs): Call bfd_install_relocation. Deleted various
2913 hacks for working around problems with bfd_perform_relocation.
2915 * Makefile.in (VERSION): Update to 2.4.90.
2917 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2930 * write.c (write_relocs): Add file name and line number to
2931 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2932 RELOC_EXPANSION_POSSIBLE.
2934 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2936 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2937 here. Use them for deciding which PRINTF*LIKE macro definitions
2939 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
2940 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2941 default definitions matching what we were doing before.
2942 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2943 always use the varargs form if not using stdarg. It's safe to
2944 always use vfprintf, because libiberty will provide it if the
2945 native system doesn't. Also, always make format be const.
2946 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
2948 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2961 (listing_newline): Check filename as well as line number when
2962 deciding whether to record it.
2963 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2964 false (if defined) as well as checking for reg_section.
2965 (listing_listing): Iterate fetching lines while line number is too
2966 low, and we haven't run off the end of the input file.
2968 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2970 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2972 * ecoff.c (ecoff_generate_asm_lineno): check if
2973 current_stabs_filename is NULL before strcmp.
2974 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
2977 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2979 * config/ho-*.h: Now-unused files deleted.
2981 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2982 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2983 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2984 zero. Don't call obj_frob_forward_symbol.
2985 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
2986 X_add_number is zero.
2987 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2989 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2991 (strchr): Don't declare.
2992 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
2993 md_estimate_size_before_relax, md_ri_to_chars,
2994 md_create_short_jump, md_create_long_jump.
2995 (brtab_emit): Use data_section, not SEG_DATA.
2997 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2999 * config/vms-conf.h: new file, manually derived from conf.in.
3000 * config-gas.com: use it, and eliminate obsolete "host.h".

3004 * config/tc-ppc.c (ppc_current_block): New static variable.
3005 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

3009 (ppc_es): Clear ppc_current_block.
3010 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3011 from the csect of the enclosing block.
3013 * config/tc-mips.c (insns_since_cache_access): Remove.
3014 (append_insn): Remove setting of insns_since_cache_access, and
3015 special 4600 handling; it turns out not to be required.
3017 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3019 * config/tc-mips.c (md_shortopts): Remove E.
3020 (md_longopts): Add EB and EL.
3021 (md_parse_option): Handle -EB and -EL as separate options, rather
3022 than as a single -E option with an argument.

3031 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3033 * configure.in: Test for remove, not delete. Fix cross-assembler
3035 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

3039 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3040 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
3041 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
3043 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
3045 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3046 many others): new macros; values obtained from "DSTRECRDS.SDL".
3047 * config/obj-vms.h (various): use them.
3048 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3049 representation (only enum bitfields can avoid being bitstrings).
3050 (bitfield_suffix, setup_basic_type): new routines.
3051 (VMS_typedef_parse): use them. Now recognize bitfields of all
3052 integral types, not just type `int'. Caveat: the representation
3053 used for bitfields still does not work for objects placed in
3054 registers, and gcc's optimizer sometimes puts small structs there.
3056 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3058 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3059 bit from const_flag.
3060 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3061 (tc_frob_label): define this to call vms_check_for_special_label,
3062 and declare the latter.
3063 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3065 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3066 (vms_check_for_special_label): new routine (tc_frob_label).
3067 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3068 and `gcc2_compiled.' labels; they won't reach here any more.
3069 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3070 double', use `vax_g_doubles' flag to select type of double.
3071 (VMS_write_object_file) [traceback setup]: don't pass symbols
3072 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3073 and TBT_Routine_End functions.

3077 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
3078 S_GET_VALUE() to avoid many repeated function calls.
3079 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
3080 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3081 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3082 be obsolete; gcc does it automatically for vms target. It's
3083 also misnamed, because it is for the "VAX C" run-time library,
3084 not the newer "DEC C" one which has much different startup code.]
3085 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3086 `S_GET_xxx(symbol) = new_value'.
3088 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3090 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
3091 not &bfd_abs_section.
3093 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3095 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
3097 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
3099 * expr.c (expr): Don't reduce the difference of two symbols in the
3100 same frag if the symbols are not in normal sections.
3102 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
3103 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
3104 (obj_attach_unwind_info): Do not define. Not needed anymore.
3105 * config/tc-hppa.c: Delete whitespace at EOL.
3106 (struct hppa_fix_struct): Delete fx_unwind field and all references.
3107 (fix_new_hppa): Last arg is now a pointer to an int. Do not
3108 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
3109 fixups, store 32bits of unwind information in the fx_addnumber
3111 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3112 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3113 pointer to 32 bits of unwind info.
3114 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3115 pointer to the dummy symbol; set the addend field to fx_addnumber.
3116 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
3117 rather than &bfd_XXX_section.
3119 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3121 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
3122 value by one; discard adjustments previously being made. From
3125 VMS- and Vax-related changes from Pat Rankin:
3126 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3127 * vmsconf.sh: no longer have make-gas.com echo text about needing
3128 to modify the gcc-vms driver when intending to use with gcc 1.x.
3129 * as.c (parse_options): suppress 'v' from std_short_options and
3130 eliminate VMS-specific conditional initialization;
3131 [default case]: check for '-v' if md_parse_options doesn't recognize
3133 [default case, #if VMS]: check for filename argument when '-v' seen;
3135 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3136 for O_big literal operands (double floats and long long ints);
3137 [VMS, md_shortopts]: add second colon after 'v';
3138 (md_parse_options) [VMS, case 'v']: check for argument, so
3139 caller can handle `-v' w/o arg.

3184 Rewrite handling of program_transform_name.
3186 * configure.in: Test for functions unlink and delete.

3192 * .gdbinit: Deleted.
3193 * aclocal.m4 (GAS_GDBINIT): Deleted.

3197 to ensure that older versions of autoconf aren't used.
3198 * Makefile.in: Added @configure_input@ line.
3199 (configure): Deleted rule.

3203 * config/obj-coff.c (fixup_segment): After handling the difference
3204 of two symbols from the same segment, set fx_subsy to NULL, to

3280 reportedly to be used on Irix 6.
3282 * config/tc-mips.c (md_pseudo_table): Handle .globl and .global.

4210 * config/tc-alpha.c (machine): New variable.
4211 (load_insn): New macro.
4212 (load_insn_table): New function.
4213 (md_begin): Call load_insn_table, once for basic instructions and
4214 once for appropriate PAL instruction table.
4215 (md_parse_option): Set `machine' based on -m##### arguments.
4216 * config/alpha-opcode.h (alpha_pal21064_opcodes): Split out from

4231 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
4233 Merged in changes from gas-2.3 net release:
4235 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
4237 * config/obj-vms.c: Replaced unchecked uses of malloc with
4240 * listing.c (list_symbol_table): Only test BFD64, not
4243 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
4244 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.
4246 * config/obj-vms.c: Removed lots of extra semicolons after
4247 compound statements.
4248 (strchr): Don't declare here.
4250 * config/ho-vax.h (realloc): Declare.

4263 VMS debugger now recognizes `long long' variables correctly.
4264 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
4265 for gcc2's predefined types "long double" (same as double, as
4266 per gcc's current state), "long long int", "long long unsigned
4267 int", and final `otherwise' case (to avoid uninitialized type
4268 and size fields). [caveat: predefined types "complex int",
4269 "complex float", "complex double", and "complex long double" are
4272 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
4273 of 0, because the latter indicates success rather than failure
4274 when passed to `exit' or return from `main' compiled by gcc2.

4277 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.

4279 allocating new symbol entry and linking it to VMS_Symbol_type_list.
4281 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
4283 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
4284 the contents of the GAS_VERSION string when falling back to it for
4285 language processor identification.

4636 * vmsconf.sh: In generated file, get ".obj" suffix right, build
4637 source files from other directories into objects in the current
4638 directory, and specify PSECT attributes explicitly to linker.
4639 Also added missing label.
4640 * Makefile.in (stamp-mk.com): Reference new variable

4704 (hppa_tc_symbol): Likewise.
4706 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
4707 elf_tc_make_sections stuff. It was there to support PA braindamage
4708 which has been fixed, and in the case of elf_tc_make_sections is
4709 redundant with elf_tc_final_processing.

4729 don't spew remainder of input file in error message.
4730 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
4731 message with reloc type and try to process remainder of file.

4743 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
4744 flag rather than signedp field. Only permit extended range if
4745 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
4746 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
4748 * config/tc-ppc.c (ppc_size): New static variable.
4749 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
4750 (md_begin): If an instruction has a size specific flag set, only
4751 add it if we are assembling that size.

4755 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
4756 cross section PC relative relocs right for COFF and ELF.
4758 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4760 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

4784 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
4786 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4787 branch with an instruction that uses $at, in case the branch is
4789 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
4790 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
4791 to make it pcrel_offset.
4792 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
4793 reloc->address; another gruesome hack to get gas reloc handling to
4796 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4798 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
4801 (emit_insn): New function.
4802 (md_assemble): Call it.
4803 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
4805 (lituse_pending): New variable. Set by anything that generates a
4806 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
4807 tested by code that might want to emit a LITUSE reloc.
4808 (emit_unaligned_io): New function. Currently calls md_assemble,
4809 but it should eventually be converted to generate the insn itself
4810 and call emit_insn directly.
4811 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
4812 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
4813 emit_bis_r): Likewise.
4814 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
4815 (alpha_ip, label get_macro): Don't emit the final instruction if
4817 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
4818 unaligned memory access macros.

4822 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4824 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
4825 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
4826 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

4838 * config/tc-mips.c (enum mips_pic_level): New enum.
4839 (mips_pic): Change from int to enum mips_pic_level. Change all
4840 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
4841 (load_address): Handle EMBEDDED_PIC.
4842 (macro): Handle EMBEDDED_PIC in all PIC cases.
4843 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
4844 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
4845 -non_shared to use NO_PIC (this is how the Irix 5 assembler
4846 works). Do not permit -G with SVR4_PIC.
4847 (s_abicalls): Warn if -G was used, and force -G 0.
4848 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
4849 anything but a.out, not just for ELF. For ECOFF, don't generate a
4850 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
4852 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
4854 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4856 * config/tc-hppa.c (create_new_space): Use ints, not chars as
4857 parameters to avoid losing when compiling with HP CC.
4858 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
4860 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4862 * Makefile.in (config-stamp): If `defs' is defined, emit a
4863 preprocessor directive to create a macro named by this value into
4864 config.new; don't explicitly go for BFD_ASSEMBLER.
4865 * configure.in: Define `defs', not `BFDDEF'. Set it to
4866 MANY_SEGMENTS for any obj-coffbfd target.
4867 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
4868 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
4870 (LOCAL_LOADLIBES): Deleted.
4871 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
4872 * config/m88kcoff.mt (TDEFINES): Ditto.

4898 bfd_set_symtab is called.
4899 (dump_section_relocs): Note whether a symbol is a section symbol
4901 (adjust_reloc_syms): For now, always supply an absolute symbol for
4902 fixups without symbols but not yet `done'. Use section_symbol to
4903 get the symbol, instead of going directly for abs_symbol.
4904 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4905 reloc is not a section symbol and is not in the symbol table.
4906 (set_symtab): New function, broken out from write_object_file.
4907 Counts symbol table instead of relying on an earlier count.
4908 (write_object_file): Call set_symtab, but do it after potentially
4909 invoking the *_frob_file macros. Don't bother counting symbols.
4910 Call symbol_remove, instead of expanding it in place. Moved the
4911 conditionalized `object_file_size' declaration down to
4912 conditionalized block where it's used. When using the absolute
4913 symbol for a fixup without a symbol, set sy_used_in_reloc.
4914 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4915 the correct symbol for the absolute section.
4917 * subsegs.c (section_symbol): Use symbol_new instead of
4918 symbol_make, since we may want it to go into the symbol table.
4919 Make the new symbol have internal linkage. If
4920 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4921 symbol with the newly created GAS symbol.
4922 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4923 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4928 (in_signed_range): New function.
4930 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4931 (sparc_ip, label "immediate"): Reject constants for pcrel
4932 instructions only if the relocation type indicates a "call"
4933 instruction and the offset is within range of a "jmpl %g0". If
4934 it's not in range, use the absolute section symbol plus an offset.
4935 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4937 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4939 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4942 * configure.in: Eliminated all targets using obj-coff but not
4943 defining BFD_ASSEMBLER; I think all such targets that are
4944 supported will be matched by real CPU-OS combinations earlier in
4946 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4947 some comments about the dpx2 configuration, but left it disabled,
4948 since it couldn't be reached before.
4949 (target a29k-amd-ebmonold): Deleted.
4951 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4959 the 'j' operand if there are no further alternatives for this
4962 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4963 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4964 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4966 * config/tc-mips.c (mips_align): Take new argument, label, and use
4967 it instead of global insn_label.
4968 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4969 call to mips_emit_delay and pass it to mips_align.
4971 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4973 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4975 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4976 argument to a .callinfo directive. Don't loop forever on errors.
4978 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4979 use pre-defined registers as arguments.

4984 S_IS_EXTERNAL when deciding whether to discard a symbol.
4986 * config-gas.com: Scan Makefile.in, not version.c, for current
4987 version number. Delete all versions of temp files when finished
4988 with them. Create config.h.
4990 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4991 values to reduce number of lookups with S_GET_VALUE. Skip debug
4992 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4993 holger@botbso.rhein-main.de.)
4994 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4995 field. (Also from Holger Teutsch.) Watch for a would-be register
4996 mask that spans frags.
4998 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4999 this_base, not line_base. (Patch from Andreas Arens,
5000 ari@obelix.av.rwth-aachen.de.)
5002 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
5003 look local if they're exported or undefined. Used to be done for
5006 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
5007 Get it from the looked-up symbol, instead of using the string from
5008 the input stream, which is no longer null-terminated.
5009 (LEX_PCT): New macro, defaults to 0.
5010 (lex_type): Use it for `%'.
5012 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
5013 (vip_op): Now static, and returns void. Callers changed. Added

5062 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
5063 0xffff for 'j' to be compatible with MIPS assembler. These
5064 numbers are actually treated as negative.

5080 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

7019 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
7020 the table, require that the one without bit 0x1000000 set come
7021 first. Require further that it be case 'b' or 'P'. The a29k
7022 opcode table already meets these constraints.
7023 (machine_ip): When handling case 'i' or 'A', make sure that the

7079 * write.c (write_relocs): For relocs that are pc_relative and
7080 pcrel_offset and not partial_inplace, adjust reloc->addend to

7133 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
7135 * configure.in: Set bfd_gas for all sparc targets. Added facility
7136 for keeping or rejecting configurations still under development;
7137 default is to assume production environment, and reject configs
7138 still being worked on. Mark Elf configurations (except sparc and
7139 i386) as developmental. Deleted cases matching some generic names
7140 in favor of more specific names. (E.g., when we get Alpha

7159 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
7160 conditional code in a few small places.
7162 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
7163 structures, global variables, forward declarations together.

7166 into a few places. Make all functions and variables which
7167 are only used within tc-hppa.c static. PARAMize all functions.
7168 Add comments to functions. Delete unused functions, variables,
7169 #defines, etc. Delete unused members within structures. Delete
7170 ldil;ble hacks -- it is believed they were installed to work
7171 around old gas bugs. Avoid using mixed case for local
7172 functions, variables, and structures. Fix formatting problems
7173 not found by GNU-indent. Add FIXME notices for things which
7174 should be worked on the near future. Delete lots of old
7175 useless (1.36 PA-SOM) code.

7204 a multiple of the section alignment rather than always a
7207 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
7208 bits are zero (eg they specify no relocations), then do not even
7209 bother adding their entries to thesymextn section.

7254 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
7256 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
7257 ELF, since the ELF object format does not have these type of
7258 relocations. Change the abort into as as_bad and return
7259 BFD_RELOC_NONE to silence compiler warnings.
7260 (md_assemble): Keep track of the instruction size. Allow white
7261 space between the $ and the constant for compatibility with older
7262 gases and other assemblers.

9706 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

9713 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

9746 dropping a space immediately following an identifier.

9748 lines; I don't think that can be done portably.
9749 * config/tc-mips.c (macro): Use $AT if target register is zero in

9824 prototypes for all static functions. Moved existing minimal
9825 debugging format support info #ifndef OBJ_ECOFF blocks.

9876 * read.c (s_ignore): Don't declare is_end_of_line. It's
9877 redundant, and triggers a VMS gcc compiler bug.
9879 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9880 current segment as an argument. (Ignored in all cases but VMS.)
9881 All callers and definitions changed.

9905 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9908 * configure.in: mips-bsd configuration was missing format spec.
9911 * Makefile.in (Makefile): Depends on configure.in.
9913 * config/tc-mips.c (append_insn): Don't check for alignment of
9914 frag in memory; alignment of instructions in section is a separate

9935 constants are accepted, but symbolic values are not. GCC will not
9936 generate the latter currently.
9938 * frags.c (frag_init): New function.
9939 (zero_address_frag, bss_address_frag): Now initialized at run
9941 * as.c (main): Call frag_init.

10212 (operand): Treat zero byte as end-of-operand.
10214 * configure.in (per-target): Look for with_bfd_assembler option.
10215 For now, only accept "no", until the merge is done.
10217 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10218 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10219 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10220 * read.c: Finish conversion to S_* macros in the VMS only
10221 parts of the program. Add "const" modifier to hex_value.
10222 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10224 * expr.c: Add "const" modifier to hex_value.
10225 * symbols.c: Finish conversion to S_* macros in the VMS only
10226 parts of the program. Add "const" modifier to
10227 md_[long,short]_jump_size. Remove declaration of const_flag

10229 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10230 Fix arguments to VMS_write_object_file.
10231 * config-gas.com: New file. Script for VMS systems to set up the
10232 configuration to build gas for VMS, and create config.status.
10233 * make-gas.com: Redone to work with new scheme.

10241 types of malformed stabs. Change parsing algorithm so that we are
10242 more certain of having all of the information that we need on hand.
10243 * obj-vms.c (final_forward_reference): New function, used to help
10244 resolve the data types of as many struct elements as possible

10262 SEG_DATA or SEG_E1 if needed.
10263 (s_lcomm): Likewise with bss_section.
10264 (s_fill): Use memset, not bzero.
10266 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

10302 declare with format attribute for -Wformat checking.
10304 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10306 * app.c, config/tc-*.c: Don't include read.h, since it is already
10309 * These are based on patches from Minh Tran-le
10310 <mtranle@paris.intellicorp.com>.
10311 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10312 obj_format coffbfd and gas_target i386coff for target.
10313 (i[34]86-*-isc*): New host (uses sysv).
10314 * config/i386aix.mt: Removed (no longer used).
10315 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10316 (MINUS_G): Removed.
10317 (LDFLAGS): Added, defined as -shlib.
10318 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10319 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10320 (DOT_LABEL_PREFIX): Define.
10321 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10322 name rather than L0\001.

10325 * symbols.c, symbols.h (local_bss_counter): Removed.
10326 * write.c (write_object_file): bss no longer uses
10327 local_bss_counter. Pass correct data and bss size to

10334 (size_section): Restored sanity check.
10335 (do_relocs_for): Base section address on s_paddr rather than
10336 computing it. Adjust a29k R_IHIHALF special case to account for
10337 section paddr (used to require paddr to be zero). If there are no
10338 reclos, set s_relptr to 0. Set relocation size in object_headers.
10339 (fill_section): Always set s_vaddr here, removing
10340 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10341 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10342 Set STYP_INFO for .comment.
10343 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10344 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

10348 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10349 set s_vaddr here. If string_byte_count remains 4, set it back to
10350 0, and only write strings out if there are some. Call
10351 fill_section before do_relocs_for and do_linenos_for.
10352 (obj_coff_section): Handle optional quoted second argument giving
10353 section characteristics.
10354 (obj_coff_bss): Added to handle .bss.

10376 (symbol_chars): Now const.
10378 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10379 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10381 * config/obj-coff.h: Don't use #elif.
10383 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10384 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10386 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

10410 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10411 using ZERO_BASED_SEGMENTS.
10412 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10413 never set segment address for SEG_E2 (.bss) and don't write out
10414 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10415 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10416 definitions, and don't merge tags with non-tags. Check for .bf
10417 rather than just checking whether the second character is b and
10418 the third character is f.
10419 (obj_coff_val): gcc can generate values which we don't handle
10420 correctly; discard information for now, since it only affects the
10421 debugging information.

10423 (yank_symbols): Don't merge labels.
10424 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10716 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10719 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10721 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10722 sections starting from zero, rather than making them consecutive.
10723 This makes subsequent reloc calculations easier, esp if the object
10724 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10725 allocate lcomm in .data rather than in .bss. It seems that some
10726 tools can't cope with a non-zero sized bss before linkage.

10730 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10731 throughout. That enum no longer means what we thought it meant.
10733 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10734 "-mno-688[58]1" options.

10752 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10754 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10755 .word is < -32768 or > 32767. The -J flag causes the error to be
10756 ignored. This is to catch over-sized switches generated by gcc on
10757 systems which don't support the broken .word hack.
10758 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10759 write.c (fixup_segment): check for signed .word overflow if
10760 WARN_SIGNED_OVERFLOW_WORD.

10793 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10794 Motorola and MIT syntax; gas can now assemble either type of
10796 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10797 From Steve Chamberlain:
10798 m68kcoff.mt: for m68k COFF.

10801 (fill_section) added rs_machine_dependent case
10802 (write_object_file) call fixup_mdeps
10803 (fixup_segment) set fx_subsy to 0.
10804 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10806 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10809 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10836 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10838 * config/tc-m68k.c (init_table): Now const. Always include 68851
10839 data, so that "bc" is available to 68040 cache instructions.
10840 Added "tt0", "tt1", and 68ec030 variants.
10841 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10842 (enum _register): Added TT0, TT1.
10843 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10844 line number correctly in "internal error" messages. Don't print
10845 architecture-mismatch message for operand errors.

10865 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10866 so that we can assemble hand-written libgcc code.
10868 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10870 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10871 has already been formatted (but may still contain %-characters).
10872 (as_bad): Likewise.
10874 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10876 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10877 written with indirection on the last two operands, which can be
10878 either data or address registers. Added a new operand type 'r'
10879 which accepts either register type. Added '(' to notend stuff in
10880 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10991 (md_assemble): If no CPU has been set (even if FPU/PMMU
10992 characteristics have been), default to 68020. Don't need extra
10993 quotes around error string.

11193 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
11195 * write.{c,h} (fix_new): Make these declarations consistent.
11197 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
11199 * Makefile.in (strerror.o): Add rule so that broken Sun make can
11202 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11204 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11206 * expr.c (operand): if can't work out what sort of operand it is,
11207 then look through FLT_CHARS for a hint.
11209 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11211 * Makefile.in, configure.in: removed traces of namesubdir,
11212 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11213 copyrights to '92, changed some from Cygnus to FSF.
11215 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11216 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11217 copyrights to '92, changed some from Cygnus to FSF.
11219 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11221 * expr.c: If an expression is single comma, then return with
11222 SEG_ABSENT rather than an error - since the sparc front end does
11223 really strange things with things like fbge,a
11225 * as.h: include bfd.h if using many sections
11226 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11227 local labels didn't work.
11228 * listing.c (list_symbol_table): don't core dump when there's no
11230 * write.c, write.h: call fix_new with the right number of args on
11232 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11235 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11237 * app.c: MRI compatibility - allow single quote to start a string.
11238 * as.c: fix typo recently introduced.
11239 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11240 * expr.c: Much rewriting, to accomodate MRI syntax for
11241 expressions. Also easier to read now.
11242 * listing.c: Put back defuns
11243 * read.c: modified to accept MRI syntax, put back listing pseudo
11244 ops so that an assembler built with NO_LISTING ignores list ops
11246 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11247 machine is a SPARC or a 29K.
11248 * config/obj-aout.c: added s_sect pseudo op
11249 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11250 fill in the timestamp.
11251 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11252 anymore, define all the relocs which the tc-<x> bit will use so we
11253 can translate from them to the coff types.
11254 * config/tc-a29k.c: reloc_type isn't ane enum any more
11255 * config/tc-m68k.c: Added NO_RELOC definition.
11257 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11259 * Makefile.in: put header files before C source for TAGS; remove
11260 references to non-existent syscalls.h.
11262 * read.c, write.c subsegs.c: back out the .bss changes.
11264 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11266 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11268 * a.out.h: removed.
11270 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11272 * symbols.c (local_label_name): symbols now start with ^A.
11274 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11275 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11276 generate these sections. .align: will use NOP_OPCODE or 0
11277 for padding. This is just for being nice to the
11280 * expr.c (operand): changed to generate local label "\001L0"
11281 starting with a ^A so that it is recognized as a local label.
11283 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11285 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11286 i/o opcodes - inb, inw, outb and outw. string manipulation with
11287 att syntax - scmp, slod, smov, ssca, ssto.
11289 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11290 to just after .file .
11292 In obj_crawl_symbol_chain() where it tries to put the external
11293 symbols apart, with the condition:
11294 (!S_IS_DEFINED(symbolP) &&
11295 !S_IS_DEBUG(symbolP) &&
11296 !SF_GET_STATICS(symbolP))
11297 it was moving too many symbols out. So I switch it back to the
11299 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11301 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11302 so that we don't use the F_RELFLG which make the linker complain
11303 that somebody has stripped the relocation info.
11305 Also, the AIX ld program require that the relocation table
11306 is sorted by r_vaddr like the standard ATT assembler does.
11308 [he also changed the sizeof(struct ...)'s into the coff
11309 style FOOSZ macros. I'm not sure this is right, but I can't
11310 remember why. xoxorich.]
11312 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11314 * Makefile.in, configure.in, doc: use the doc. Build it, install
11317 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11319 * read.c: white space and comments only.
11321 * configure.in: use the new atof-ns32.c for ns32k.
11323 * write.c: comment change only.
11325 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11326 aren't yet integrated.
11328 * tc-i860.[hc]: blew off the dust. Something must still be done
11329 about conflicting relocation types.
11331 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11334 * tc-i960.c, tc-sparc.c: white space and comments only.
11336 * tc-a29k.h: delete duplicate macro definition.
11338 * new file atof-ns32k.c copied from hack's last unreleased gas.
11340 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11342 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11345 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11346 ChangeLog's prior to this are sketchy at best. I have logs.
11347 They just aren't ChangeLogs.
