2933 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2934 it's better to use the one in libiberty.
2936 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2938 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2976 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2977 running the binary through sed to avoid differences due to

2992 (obj_elf_size): Deleted unused code. If size is non-reducible
2993 expression, allocate some storage for the sy_obj field and copy

2996 ecoff_frob_symbol if appropriate.
2998 * write.c (fixup_segment): For i386 elf and coff (for now), don't
2999 add in value of symbol from another defined section of the file.

3102 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3104 * configure.in: Set bfd_gas for all sparc targets in one place,
3105 instead of separately for each. Correctly handle user-supplied
3106 "--enable-bfd-gas" option.
3108 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3110 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
3113 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
3114 processing if add_symbol is undefined or in expr_section.
3115 (resolve_symbol_value, case O_add): For symbol plus
3116 constant-valued symbol, convert to O_symbol and re-reduce.
3117 (S_GET_VALUE): If symbol needs resolving, resolve it.
3118 (indent_level): No longer static.
3119 (print_symbol_value_1): Don't print frag address if it matches
3120 zero_address_frag. Don't print "resolving" if already resolved.

3123 (print_expr_1): Fix whitespace before printing X_add_number.
3125 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3126 not symbol_new, for symbols holding expression values.
3127 * expr.h (make_expr_symbol): Move declaration here.
3128 * write.c (fix_new_exp): Handle O_add by creating an
3129 expression-valued symbol, and calling fix_new_exp recursively.
3130 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3131 undefined symbol and a constant, fold the constant into the fixup,
3132 and refer to the undefined symbol directly. Then process the
3133 fixup again from scratch.
3134 (write_object_file): Before calling adjust_reloc_syms, make a pass
3135 through the symbol list trying to resolve values.
3137 * write.c (print_fixup): New routine, for debugging.
3138 (write_relocs): Call bfd_install_relocation. Deleted various

3156 * write.c (write_relocs): Add file name and line number to
3157 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3158 RELOC_EXPANSION_POSSIBLE.
3160 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3162 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
3163 here. Use them for deciding which PRINTF*LIKE macro definitions

3167 default definitions matching what we were doing before.
3168 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3169 always use the varargs form if not using stdarg. It's safe to
3170 always use vfprintf, because libiberty will provide it if the
3171 native system doesn't. Also, always make format be const.
3172 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3190 false (if defined) as well as checking for reg_section.
3191 (listing_listing): Iterate fetching lines while line number is too
3192 low, and we haven't run off the end of the input file.
3194 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3196 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

3207 * symbols.c (copy_symbol_attributes): New function. Copies BFD
3208 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
3209 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
3210 zero. Don't call obj_frob_forward_symbol.
3211 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
3212 X_add_number is zero.
3213 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
3215 * config/tc-i960.c: Lots of whitespace, comment reformatting,
3217 (strchr): Don't declare.

3219 md_estimate_size_before_relax, md_ri_to_chars,
3220 md_create_short_jump, md_create_long_jump.
3221 (brtab_emit): Use data_section, not SEG_DATA.
3223 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3225 * config/vms-conf.h: new file, manually derived from conf.in.
3226 * config-gas.com: use it, and eliminate obsolete "host.h".

3236 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
3237 from the csect of the enclosing block.
3239 * config/tc-mips.c (insns_since_cache_access): Remove.
3240 (append_insn): Remove setting of insns_since_cache_access, and
3241 special 4600 handling; it turns out not to be required.
3243 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3245 * config/tc-mips.c (md_shortopts): Remove E.
3246 (md_longopts): Add EB and EL.
3247 (md_parse_option): Handle -EB and -EL as separate options, rather
3248 than as a single -E option with an argument.
3250 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
3252 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3253 involving global symbols too.
3255 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3257 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3259 * configure.in: Test for remove, not delete. Fix cross-assembler
3261 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

3265 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
3266 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

3271 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
3272 many others): new macros; values obtained from "DSTRECRDS.SDL".
3273 * config/obj-vms.h (various): use them.
3274 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
3275 representation (only enum bitfields can avoid being bitstrings).
3276 (bitfield_suffix, setup_basic_type): new routines.
3277 (VMS_typedef_parse): use them. Now recognize bitfields of all
3278 integral types, not just type `int'. Caveat: the representation
3279 used for bitfields still does not work for objects placed in
3280 registers, and gcc's optimizer sometimes puts small structs there.
3282 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3284 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3285 bit from const_flag.
3286 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
3287 (tc_frob_label): define this to call vms_check_for_special_label,
3288 and declare the latter.
3289 * config/obj-vms.c (vax_g_doubles): declare this file-scope
3291 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
3292 (vms_check_for_special_label): new routine (tc_frob_label).
3293 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3294 and `gcc2_compiled.' labels; they won't reach here any more.
3295 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3296 double', use `vax_g_doubles' flag to select type of double.
3297 (VMS_write_object_file) [traceback setup]: don't pass symbols
3298 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
3299 and TBT_Routine_End functions.

3306 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3307 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3308 be obsolete; gcc does it automatically for vms target. It's
3309 also misnamed, because it is for the "VAX C" run-time library,
3310 not the newer "DEC C" one which has much different startup code.]
3311 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3312 `S_GET_xxx(symbol) = new_value'.

3335 fixups, store 32bits of unwind information in the fx_addnumber
3337 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3338 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3339 pointer to 32 bits of unwind info.
3340 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3341 pointer to the dummy symbol; set the addend field to fx_addnumber.
3342 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
3343 rather than &bfd_XXX_section.

3348 value by one; discard adjustments previously being made. From
3351 VMS- and Vax-related changes from Pat Rankin:
3352 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3353 * vmsconf.sh: no longer have make-gas.com echo text about needing
3354 to modify the gcc-vms driver when intending to use with gcc 1.x.
3355 * as.c (parse_options): suppress 'v' from std_short_options and
3356 eliminate VMS-specific conditional initialization;
3357 [default case]: check for '-v' if md_parse_options doesn't recognize

3361 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3362 for O_big literal operands (double floats and long long ints);
3363 [VMS, md_shortopts]: add second colon after 'v';
3364 (md_parse_options) [VMS, case 'v']: check for argument, so

3563 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3564 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3565 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3566 message to try to ease confusion about autoconf's

4313 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4315 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4316 to put a common symbol in a set.

4361 * read.c (emit_expr): Use memset to zero out memory, rather than
4362 going through md_number_to_chars. This permits handling symbolic
4363 arguments when the size is larger than sizeof (valueT), if

4416 (control_regs): New pointer.
4417 (m68k_ip): Use control_regs instead of testing CPU every time.
4418 Use last_movec_reg too. In error messages, handle 68060, and
4419 print 68060 for mfloat, too.
4420 (m68k_init_after_args): Handle "68060". Use m68040up for making
4421 m68851 choice. Set control_regs.

4933 elf_tc_make_sections stuff. It was there to support PA braindamage
4934 which has been fixed, and in the case of elf_tc_make_sections is
4935 redundant with elf_tc_final_processing.
4937 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5038 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5070 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
5071 -non_shared to use NO_PIC (this is how the Irix 5 assembler
5072 works). Do not permit -G with SVR4_PIC.
5073 (s_abicalls): Warn if -G was used, and force -G 0.
5074 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5124 bfd_set_symtab is called.
5125 (dump_section_relocs): Note whether a symbol is a section symbol
5127 (adjust_reloc_syms): For now, always supply an absolute symbol for
5128 fixups without symbols but not yet `done'. Use section_symbol to
5129 get the symbol, instead of going directly for abs_symbol.
5130 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5131 reloc is not a section symbol and is not in the symbol table.
5132 (set_symtab): New function, broken out from write_object_file.
5133 Counts symbol table instead of relying on an earlier count.
5134 (write_object_file): Call set_symtab, but do it after potentially
5135 invoking the *_frob_file macros. Don't bother counting symbols.
5136 Call symbol_remove, instead of expanding it in place. Moved the
5137 conditionalized `object_file_size' declaration down to
5138 conditionalized block where it's used. When using the absolute
5139 symbol for a fixup without a symbol, set sy_used_in_reloc.
5140 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5141 the correct symbol for the absolute section.
5143 * subsegs.c (section_symbol): Use symbol_new instead of
5144 symbol_make, since we may want it to go into the symbol table.
5145 Make the new symbol have internal linkage. If
5146 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5147 symbol with the newly created GAS symbol.
5148 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

5156 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5157 (sparc_ip, label "immediate"): Reject constants for pcrel
5158 instructions only if the relocation type indicates a "call"
5159 instruction and the offset is within range of a "jmpl %g0". If
5160 it's not in range, use the absolute section symbol plus an offset.
5161 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5163 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5165 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5168 * configure.in: Eliminated all targets using obj-coff but not
5169 defining BFD_ASSEMBLER; I think all such targets that are
5170 supported will be matched by real CPU-OS combinations earlier in
5172 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5173 some comments about the dpx2 configuration, but left it disabled,
5174 since it couldn't be reached before.
5175 (target a29k-amd-ebmonold): Deleted.

5185 the 'j' operand if there are no further alternatives for this
5188 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5189 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5190 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5192 * config/tc-mips.c (mips_align): Take new argument, label, and use
5193 it instead of global insn_label.
5194 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5195 call to mips_emit_delay and pass it to mips_align.
5197 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5199 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

5209 * write.c (write_object_file): Check both S_IS_LOCAL and
5210 S_IS_EXTERNAL when deciding whether to discard a symbol.
5212 * config-gas.com: Scan Makefile.in, not version.c, for current
5213 version number. Delete all versions of temp files when finished
5214 with them. Create config.h.
5216 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
5217 values to reduce number of lookups with S_GET_VALUE. Skip debug
5218 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5219 holger@botbso.rhein-main.de.)
5220 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5221 field. (Also from Holger Teutsch.) Watch for a would-be register
5222 mask that spans frags.
5224 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5225 this_base, not line_base. (Patch from Andreas Arens,

5229 look local if they're exported or undefined. Used to be done for
5232 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

5236 (lex_type): Use it for `%'.
5238 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

7362 for keeping or rejecting configurations still under development;
7363 default is to assume production environment, and reject configs
7364 still being worked on. Mark Elf configurations (except sparc and
7365 i386) as developmental. Deleted cases matching some generic names
7366 in favor of more specific names. (E.g., when we get Alpha

7392 into a few places. Make all functions and variables which
7393 are only used within tc-hppa.c static. PARAMize all functions.
7394 Add comments to functions. Delete unused functions, variables,
7395 #defines, etc. Delete unused members within structures. Delete
7396 ldil;ble hacks -- it is believed they were installed to work
7397 around old gas bugs. Avoid using mixed case for local
7398 functions, variables, and structures. Fix formatting problems
7399 not found by GNU-indent. Add FIXME notices for things which
7400 should be worked on the near future. Delete lots of old
7401 useless (1.36 PA-SOM) code.

8563 * Extensive changes to permit symbols to contain any expression
8564 type and to delay the computation of the expression until the
8565 value is actually needed. This permits setting symbols to values
8566 calculated based on object code size. Expressions were changed to
8567 no longer be in a section, to stop the overloading of segment and
8568 expression type that previously occurred.
8570 * as.c (big_section, pass1_section, diff_section, absent_section):
8572 (expr_section): Added (used for dummy symbols which hold

8658 to pop back to it. Handle unquoted section name as well as quoted
8659 section name. Don't crash on invalid strings.
8660 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8769 * Removed sy_forward and replaced it with an undefined expression
8770 as the value of a symbol.

8772 sy_resolved and sy_resolving single bit fields.
8773 * symbols.c (symbol_new): Don't initialize sy_forward field.

9807 than ECOFF line number information.
9808 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9887 (srcdir): Delete second, bogus definition.
9888 (as.info): Look for as-*.texinfo in current directory rather than

9893 source directory, if that's not the current directory.
9895 * configure.in (per-host): Accept MIPS host with BSD version

9916 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9917 process relocs if there aren't any relocs to process. Avoids
9918 malloc/free bug on SCO too.

9921 avoid some redefinition complaints on some systems.
9922 (const, volatile): Don't need these conditionally defined if we
9923 use CONST and VOLATILE from ansidecl.h.
9924 (seg_name): Use CONST, not const.
9926 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9928 * config/tc-mips.c: Reindented to GNU standards.
9930 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9932 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9933 (fixup_segment): Add a29k special case; the linker is not prepared
9934 to see a segment offset here.
9936 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9937 9 to only keep a space in between identifier characters.
9939 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9941 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9942 srcdir, might be in objdir.
9944 * doc/Makefile.in: dvi depends on as.dvi

9967 * Makefile.in (targ-cpu.o): Depend on config.h.
9969 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9971 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9972 dropping a space immediately following an identifier.
9973 * expr.c, write.c: Rewrote assert expressions to not use multiple
9974 lines; I don't think that can be done portably.
9975 * config/tc-mips.c (macro): Use $AT if target register is zero in
9976 load instruction, which it can be for a floating point load.
9978 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9986 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9989 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9990 z8k-opc.h, not z8k.h.
9992 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9995 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9997 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9999 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

10050 prototypes for all static functions. Moved existing minimal
10051 debugging format support info #ifndef OBJ_ECOFF blocks.
10052 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10053 does not support a non sign extended high 16 bits reloc. Adjusted
10054 all callers accordingly.

10100 * make-gas.com: Find obstack.obj if it's not in the current
10102 * read.c (s_ignore): Don't declare is_end_of_line. It's
10103 redundant, and triggers a VMS gcc compiler bug.
10105 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10106 current segment as an argument. (Ignored in all cases but VMS.)
10107 All callers and definitions changed.

10131 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10134 * configure.in: mips-bsd configuration was missing format spec.

10160 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10161 constants are accepted, but symbolic values are not. GCC will not
10162 generate the latter currently.

10210 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10211 (fixup_segment): Make sure common-section symbols get treated the
10212 same as undefined symbols.

10218 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10219 md_section_align, md_undefined_symbol): Don't provide prototypes
10220 if these are defined as macros.
10221 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10417 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10418 md_relax_table): Use default zero initialization.
10419 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10432 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10434 * expr.c (operand): If character other than comma or newline is a
10435 logical end-of-line character, use the newline case.
10436 From Eric Youngdale:
10437 (operand): Set X_add_number field for floating-point numbers.
10438 (operand): Treat zero byte as end-of-operand.
10440 * configure.in (per-target): Look for with_bfd_assembler option.
10441 For now, only accept "no", until the merge is done.
10443 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10444 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10445 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10446 * read.c: Finish conversion to S_* macros in the VMS only
10447 parts of the program. Add "const" modifier to hex_value.
10448 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10450 * expr.c: Add "const" modifier to hex_value.
10451 * symbols.c: Finish conversion to S_* macros in the VMS only
10452 parts of the program. Add "const" modifier to
10453 md_[long,short]_jump_size. Remove declaration of const_flag
10454 (which will be declared in obj-vms.h).
10455 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10456 Fix arguments to VMS_write_object_file.
10457 * config-gas.com: New file. Script for VMS systems to set up the
10458 configuration to build gas for VMS, and create config.status.
10459 * make-gas.com: Redone to work with new scheme.
10460 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10462 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10463 will swap bytes if needed on a big endian system. Use throughout
10465 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10466 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10467 types of malformed stabs. Change parsing algorithm so that we are
10468 more certain of having all of the information that we need on hand.
10469 * obj-vms.c (final_forward_reference): New function, used to help
10470 resolve the data types of as many struct elements as possible
10471 when some part of the struct is not fully defined by the compiler.
10472 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10474 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10475 as symbols as well in the object file. Look for external functions

10478 * tc-vax.c: Add '1' option for backward compatibility with older GCC
10480 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

10485 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10487 * read.c (s_data): Always use "data_section", since it'll map to
10488 SEG_DATA or SEG_E1 if needed.
10489 (s_lcomm): Likewise with bss_section.
10490 (s_fill): Use memset, not bzero.
10492 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10494 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10512 (seg_name): Declare only if not BFD_ASSEMBLER.
10513 (section_alignment): Declare only if not BFD_ASSEMBLER.
10514 (big_section, reg_section, pass1_section, diff_section,
10515 absent_section, text_section, data_section, bss_section): If
10516 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10517 mapping to segT enum values.
10518 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10519 if these are used or defined, if BFD_ASSEMBLER.
10520 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10521 subseg_new split into two functions.
10522 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10524 * as.h (volatile): Don't define if already defined.
10525 (had_errors, had_warnings): Provide prototypes for ANSI C even if

10528 declare with format attribute for -Wformat checking.
10530 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10532 * app.c, config/tc-*.c: Don't include read.h, since it is already

10536 <mtranle@paris.intellicorp.com>.
10537 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10538 obj_format coffbfd and gas_target i386coff for target.
10539 (i[34]86-*-isc*): New host (uses sysv).
10540 * config/i386aix.mt: Removed (no longer used).
10541 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10542 (MINUS_G): Removed.
10543 (LDFLAGS): Added, defined as -shlib.
10544 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10545 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10546 (DOT_LABEL_PREFIX): Define.
10547 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10548 name rather than L0\001.

10551 * symbols.c, symbols.h (local_bss_counter): Removed.
10552 * write.c (write_object_file): bss no longer uses
10553 local_bss_counter. Pass correct data and bss size to
10554 VMS_write_object_file.
10555 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10556 argument, rather than using local_bss_counter.

10560 (size_section): Restored sanity check.
10561 (do_relocs_for): Base section address on s_paddr rather than
10562 computing it. Adjust a29k R_IHIHALF special case to account for
10563 section paddr (used to require paddr to be zero). If there are no
10564 reclos, set s_relptr to 0. Set relocation size in object_headers.
10565 (fill_section): Always set s_vaddr here, removing
10566 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10567 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10568 Set STYP_INFO for .comment.
10569 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10570 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
10571 (crawl_symbols): Handle 8 character section name correctly. Use
10572 H_{SET,GET}_* macros.
10573 (do_linenos_for): Set lineno size in object_headers.
10574 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10575 set s_vaddr here. If string_byte_count remains 4, set it back to
10576 0, and only write strings out if there are some. Call
10577 fill_section before do_relocs_for and do_linenos_for.
10578 (obj_coff_section): Handle optional quoted second argument giving
10579 section characteristics.
10580 (obj_coff_bss): Added to handle .bss.
10581 (obj_coff_ident): Added to handle .ident (puts string in .comment

10601 (do_scrub_next_char): For \", return " not '.
10602 (symbol_chars): Now const.
10604 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10605 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10607 * config/obj-coff.h: Don't use #elif.
10609 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10610 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10612 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10614 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10626 * read.c (read_a_source_file): avoid calling xmalloc (0).
10628 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
10630 * listing.c: Call xmalloc, not malloc; don't declare malloc.
10632 * Changes to support SCO 3.2v4:
10633 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10634 SEG_BSS, fill with NOP_OPCODE.
10635 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10636 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10637 using ZERO_BASED_SEGMENTS.
10638 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10639 never set segment address for SEG_E2 (.bss) and don't write out
10640 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10641 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10642 definitions, and don't merge tags with non-tags. Check for .bf
10643 rather than just checking whether the second character is b and
10644 the third character is f.
10645 (obj_coff_val): gcc can generate values which we don't handle
10646 correctly; discard information for now, since it only affects the
10647 debugging information.
10648 (tag_find_or_name): Don't insert tags in the symbol table.
10649 (yank_symbols): Don't merge labels.
10650 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10652 set segment address if ZERO_BASED_SEGMENTS.
10653 (obj_coff_section): Accept and ignore a trailing quoted string, as
10654 used in AT&T i386 syntax.

10656 relative addends by the segment vaddr.
10657 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10658 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
10659 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

10800 z8000 documentation
10801 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10804 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10806 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10808 * subsegs.h: add extern to segment_info declaration.
10810 * read.h: added extern declarations for comment_chars,
10811 line_comment_chars, and line_separator_chars.
10812 read.c, app.c: removed definitions of comment_chars,
10813 line_comment_chars, and line_separator_chars.

10832 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10833 constant will not fit in an immediate field.
10834 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
10836 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
10838 * obj-coff.c (callj_table): Delete global variable.
10839 (obj_emit_relocations): Define it locally here, and only if
10840 TC_I960 is defined.
10842 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10869 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
10871 * Support for i386-sysv.
10872 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10873 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10874 be used to set them all to zero as was done before.
10875 (fill_section): segment addresses now set in write_object_file.
10876 (fill_section): Don't set STYP_NOLOAD for .bss section.
10877 (fixup_segment): 386 uses strange common symbol format.

10912 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10914 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10915 #elif, since it is not supported by old compilers.
10916 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10917 couple of expressions in tc-m68k.c.
10919 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10921 * read.c (cons): If NO_RELOC is defined, use it.

10927 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10928 local labels to start with a .) and set REGISTER_PREFIX to %.
10929 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10931 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10933 * messages.c: Comment changes.
10935 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

10938 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10940 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10942 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10945 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10947 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10948 sections starting from zero, rather than making them consecutive.
10949 This makes subsequent reloc calculations easier, esp if the object
10950 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10951 allocate lcomm in .data rather than in .bss. It seems that some
10952 tools can't cope with a non-zero sized bss before linkage.
10954 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10956 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10957 throughout. That enum no longer means what we thought it meant.
10959 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10960 "-mno-688[58]1" options.
10962 * tc-m68k.c: Added CPU32 support.
10964 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10966 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

10975 * Makefile.in (install): if $(tooldir) exists, install as in
10978 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10980 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10981 .word is < -32768 or > 32767. The -J flag causes the error to be
10982 ignored. This is to catch over-sized switches generated by gcc on
10983 systems which don't support the broken .word hack.
10984 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10985 write.c (fixup_segment): check for signed .word overflow if
10986 WARN_SIGNED_OVERFLOW_WORD.
10988 * write.c (fixup_segment): fixed missing parens in expression
10989 checking for byte or word overflow.
10991 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10992 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10993 WARN_SIGNED_OVERFLOW_WORD.
10995 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10996 expression checking for byte or word overflow.

11005 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
11007 * input-scrub.c (input_scrub_push): call input_file_begin, not
11009 messages.c (as_perror): print ": " between the passed in error and
11010 the strerror, like perror does.
11012 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

11019 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11020 Motorola and MIT syntax; gas can now assemble either type of
11022 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11023 From Steve Chamberlain:
11024 m68kcoff.mt: for m68k COFF.
11025 obj-coffbfd.c: (fixup_mdeps) added
11026 (size_section) removed bad sanity check
11027 (fill_section) added rs_machine_dependent case
11028 (write_object_file) call fixup_mdeps
11029 (fixup_segment) set fx_subsy to 0.
11030 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11032 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11035 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11059 tc-i960.c (md_ri_to_chars): Always output bout object file in
11060 little endian byte order (used to use endianness of host).
11062 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11064 * config/tc-m68k.c (init_table): Now const. Always include 68851
11065 data, so that "bc" is available to 68040 cache instructions.
11066 Added "tt0", "tt1", and 68ec030 variants.
11067 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11068 (enum _register): Added TT0, TT1.
11069 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11070 line number correctly in "internal error" messages. Don't print
11071 architecture-mismatch message for operand errors.
11073 From Colin Smith (colin@wrs.com):
11074 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11075 than install_operand.
11077 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11079 * listing.c (buffer_line): rewind to the start of include
11080 files, they might be included twice.
11082 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11084 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11086 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11087 one element of a family.
11089 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11091 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11092 so that we can assemble hand-written libgcc code.
11094 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11096 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11097 has already been formatted (but may still contain %-characters).
11098 (as_bad): Likewise.
11100 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11102 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11103 written with indirection on the last two operands, which can be
11104 either data or address registers. Added a new operand type 'r'
11105 which accepts either register type. Added '(' to notend stuff in
11106 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11108 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11110 * as.h (enum _relax_state): Start off at one, not zero, to better
11111 catch uninitialized-variable errors.
11112 (linkrelax): Declare new variable.
11114 * messages.c (warning_count, error_count): Default initializer is
11117 * write.c: Merged some declarations, using PARMS macro.

11119 data_last_frag): No longer static.
11120 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11121 defined, call it. Change segments before calling fixup_segment.
11122 (relax_align): If linkrelax, provide extra padding.
11124 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11125 their not having symbols associated.
11127 * tc-i960.c (norelax, instrument_branches): Default initializer is
11129 (linkrelax): Delete variable definition.

11217 (md_assemble): If no CPU has been set (even if FPU/PMMU
11218 characteristics have been), default to 68020. Don't need extra
11219 quotes around error string.

11357 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11358 where gcc looks for it.
11360 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11362 * Makefile.in: Changed some lines to be less confusing for some

11402 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11404 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11428 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11430 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11432 * expr.c (operand): if can't work out what sort of operand it is,
11433 then look through FLT_CHARS for a hint.
11435 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11437 * Makefile.in, configure.in: removed traces of namesubdir,
11438 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11439 copyrights to '92, changed some from Cygnus to FSF.
11441 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11442 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11443 copyrights to '92, changed some from Cygnus to FSF.
11445 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11447 * expr.c: If an expression is single comma, then return with
11448 SEG_ABSENT rather than an error - since the sparc front end does
11449 really strange things with things like fbge,a
11451 * as.h: include bfd.h if using many sections
11452 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11453 local labels didn't work.
11454 * listing.c (list_symbol_table): don't core dump when there's no
11456 * write.c, write.h: call fix_new with the right number of args on
11458 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11461 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11463 * app.c: MRI compatibility - allow single quote to start a string.
11464 * as.c: fix typo recently introduced.
11465 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11466 * expr.c: Much rewriting, to accomodate MRI syntax for
11467 expressions. Also easier to read now.
11468 * listing.c: Put back defuns
11469 * read.c: modified to accept MRI syntax, put back listing pseudo
11470 ops so that an assembler built with NO_LISTING ignores list ops
11472 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11473 machine is a SPARC or a 29K.
11474 * config/obj-aout.c: added s_sect pseudo op
11475 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11476 fill in the timestamp.
11477 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11478 anymore, define all the relocs which the tc-<x> bit will use so we
11479 can translate from them to the coff types.
11480 * config/tc-a29k.c: reloc_type isn't ane enum any more
11481 * config/tc-m68k.c: Added NO_RELOC definition.
11483 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11485 * Makefile.in: put header files before C source for TAGS; remove
11486 references to non-existent syscalls.h.
11488 * read.c, write.c subsegs.c: back out the .bss changes.
11490 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11492 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11494 * a.out.h: removed.
11496 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11498 * symbols.c (local_label_name): symbols now start with ^A.
11500 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11501 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11502 generate these sections. .align: will use NOP_OPCODE or 0
11503 for padding. This is just for being nice to the
11506 * expr.c (operand): changed to generate local label "\001L0"
11507 starting with a ^A so that it is recognized as a local label.
11509 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11511 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11512 i/o opcodes - inb, inw, outb and outw. string manipulation with
11513 att syntax - scmp, slod, smov, ssca, ssto.
11515 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11516 to just after .file .
11518 In obj_crawl_symbol_chain() where it tries to put the external
11519 symbols apart, with the condition:
11520 (!S_IS_DEFINED(symbolP) &&
11521 !S_IS_DEBUG(symbolP) &&
11522 !SF_GET_STATICS(symbolP))
11523 it was moving too many symbols out. So I switch it back to the
11525 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11527 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11528 so that we don't use the F_RELFLG which make the linker complain
11529 that somebody has stripped the relocation info.
11531 Also, the AIX ld program require that the relocation table
11532 is sorted by r_vaddr like the standard ATT assembler does.
11534 [he also changed the sizeof(struct ...)'s into the coff
11535 style FOOSZ macros. I'm not sure this is right, but I can't
11536 remember why. xoxorich.]
11538 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11540 * Makefile.in, configure.in, doc: use the doc. Build it, install

11545 * read.c: white space and comments only.
11547 * configure.in: use the new atof-ns32.c for ns32k.
11549 * write.c: comment change only.
11551 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11552 aren't yet integrated.
11554 * tc-i860.[hc]: blew off the dust. Something must still be done
11555 about conflicting relocation types.
11557 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11560 * tc-i960.c, tc-sparc.c: white space and comments only.
11562 * tc-a29k.h: delete duplicate macro definition.
11564 * new file atof-ns32k.c copied from hack's last unreleased gas.
11566 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11568 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11571 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11572 ChangeLog's prior to this are sketchy at best. I have logs.
11573 They just aren't ChangeLogs.
