2919 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2920 it's better to use the one in libiberty.
2922 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2924 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2962 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2963 running the binary through sed to avoid differences due to

2982 ecoff_frob_symbol if appropriate.
2984 * write.c (fixup_segment): For i386 elf and coff (for now), don't

3088 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3090 * configure.in: Set bfd_gas for all sparc targets in one place,
3091 instead of separately for each. Correctly handle user-supplied
3092 "--enable-bfd-gas" option.
3094 * gdbinit.in: Move "break abort" to end, in case gdb complains.
3096 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

3104 (indent_level): No longer static.
3105 (print_symbol_value_1): Don't print frag address if it matches

3111 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
3112 not symbol_new, for symbols holding expression values.

3114 * write.c (fix_new_exp): Handle O_add by creating an
3115 expression-valued symbol, and calling fix_new_exp recursively.
3116 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
3117 undefined symbol and a constant, fold the constant into the fixup,
3118 and refer to the undefined symbol directly. Then process the
3119 fixup again from scratch.
3120 (write_object_file): Before calling adjust_reloc_syms, make a pass
3121 through the symbol list trying to resolve values.
3123 * write.c (print_fixup): New routine, for debugging.
3124 (write_relocs): Call bfd_install_relocation. Deleted various

3142 * write.c (write_relocs): Add file name and line number to
3143 as_fatal calls. Handle bfd_reloc_overflow case specifically when
3144 RELOC_EXPANSION_POSSIBLE.
3146 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3148 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these

3153 default definitions matching what we were doing before.
3154 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
3155 always use the varargs form if not using stdarg. It's safe to
3156 always use vfprintf, because libiberty will provide it if the
3157 native system doesn't. Also, always make format be const.
3158 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

3176 false (if defined) as well as checking for reg_section.
3177 (listing_listing): Iterate fetching lines while line number is too
3178 low, and we haven't run off the end of the input file.
3180 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
3182 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

3198 X_add_number is zero.
3199 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.

3205 md_estimate_size_before_relax, md_ri_to_chars,
3206 md_create_short_jump, md_create_long_jump.
3207 (brtab_emit): Use data_section, not SEG_DATA.
3209 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3211 * config/vms-conf.h: new file, manually derived from conf.in.

3225 * config/tc-mips.c (insns_since_cache_access): Remove.
3226 (append_insn): Remove setting of insns_since_cache_access, and
3227 special 4600 handling; it turns out not to be required.
3229 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3231 * config/tc-mips.c (md_shortopts): Remove E.
3232 (md_longopts): Add EB and EL.
3233 (md_parse_option): Handle -EB and -EL as separate options, rather
3234 than as a single -E option with an argument.

3238 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
3239 involving global symbols too.

3243 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
3245 * configure.in: Test for remove, not delete. Fix cross-assembler

3261 representation (only enum bitfields can avoid being bitstrings).
3262 (bitfield_suffix, setup_basic_type): new routines.
3263 (VMS_typedef_parse): use them. Now recognize bitfields of all
3264 integral types, not just type `int'. Caveat: the representation
3265 used for bitfields still does not work for objects placed in
3266 registers, and gcc's optimizer sometimes puts small structs there.
3268 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
3270 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
3271 bit from const_flag.
3272 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

3278 (vms_check_for_special_label): new routine (tc_frob_label).
3279 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
3280 and `gcc2_compiled.' labels; they won't reach here any more.
3281 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
3282 double', use `vax_g_doubles' flag to select type of double.
3283 (VMS_write_object_file) [traceback setup]: don't pass symbols
3284 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin

3292 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
3293 gets requested. [All the HACK_DEC_C_STARTUP code appears to
3294 be obsolete; gcc does it automatically for vms target. It's
3295 also misnamed, because it is for the "VAX C" run-time library,
3296 not the newer "DEC C" one which has much different startup code.]
3297 {various}: use `S_SET_xxx(symbol,new_value)' rather than
3298 `S_GET_xxx(symbol) = new_value'.

3321 fixups, store 32bits of unwind information in the fx_addnumber
3323 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
3324 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
3325 pointer to 32 bits of unwind info.
3326 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
3327 pointer to the dummy symbol; set the addend field to fx_addnumber.

3337 VMS- and Vax-related changes from Pat Rankin:
3338 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
3339 * vmsconf.sh: no longer have make-gas.com echo text about needing
3340 to modify the gcc-vms driver when intending to use with gcc 1.x.
3341 * as.c (parse_options): suppress 'v' from std_short_options and
3342 eliminate VMS-specific conditional initialization;
3343 [default case]: check for '-v' if md_parse_options doesn't recognize

3347 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
3348 for O_big literal operands (double floats and long long ints);
3349 [VMS, md_shortopts]: add second colon after 'v';
3350 (md_parse_options) [VMS, case 'v']: check for argument, so

3549 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3550 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3551 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3552 message to try to ease confusion about autoconf's

4301 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
4302 to put a common symbol in a set.

4347 * read.c (emit_expr): Use memset to zero out memory, rather than
4348 going through md_number_to_chars. This permits handling symbolic

4402 (control_regs): New pointer.
4403 (m68k_ip): Use control_regs instead of testing CPU every time.

4405 print 68060 for mfloat, too.
4406 (m68k_init_after_args): Handle "68060". Use m68040up for making
4407 m68851 choice. Set control_regs.

4919 elf_tc_make_sections stuff. It was there to support PA braindamage
4920 which has been fixed, and in the case of elf_tc_make_sections is
4921 redundant with elf_tc_final_processing.

5024 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

5058 works). Do not permit -G with SVR4_PIC.
5059 (s_abicalls): Warn if -G was used, and force -G 0.
5060 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

5109 * write.c (symbol_table_frozen): New variable, to be set after
5110 bfd_set_symtab is called.
5111 (dump_section_relocs): Note whether a symbol is a section symbol
5113 (adjust_reloc_syms): For now, always supply an absolute symbol for
5114 fixups without symbols but not yet `done'. Use section_symbol to
5115 get the symbol, instead of going directly for abs_symbol.
5116 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
5117 reloc is not a section symbol and is not in the symbol table.
5118 (set_symtab): New function, broken out from write_object_file.
5119 Counts symbol table instead of relying on an earlier count.
5120 (write_object_file): Call set_symtab, but do it after potentially
5121 invoking the *_frob_file macros. Don't bother counting symbols.
5122 Call symbol_remove, instead of expanding it in place. Moved the
5123 conditionalized `object_file_size' declaration down to
5124 conditionalized block where it's used. When using the absolute
5125 symbol for a fixup without a symbol, set sy_used_in_reloc.
5126 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
5127 the correct symbol for the absolute section.
5129 * subsegs.c (section_symbol): Use symbol_new instead of
5130 symbol_make, since we may want it to go into the symbol table.
5131 Make the new symbol have internal linkage. If
5132 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
5133 symbol with the newly created GAS symbol.
5134 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

5142 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
5143 (sparc_ip, label "immediate"): Reject constants for pcrel
5144 instructions only if the relocation type indicates a "call"
5145 instruction and the offset is within range of a "jmpl %g0". If
5146 it's not in range, use the absolute section symbol plus an offset.
5147 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
5149 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
5151 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
5154 * configure.in: Eliminated all targets using obj-coff but not
5155 defining BFD_ASSEMBLER; I think all such targets that are
5156 supported will be matched by real CPU-OS combinations earlier in
5158 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
5159 some comments about the dpx2 configuration, but left it disabled,
5160 since it couldn't be reached before.
5161 (target a29k-amd-ebmonold): Deleted.

5171 the 'j' operand if there are no further alternatives for this
5174 * config/obj-coffbfd.c (adjust_stab_section): Initialize
5175 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
5176 is not SEG_UNKNOWN rather than checking whether it is >= 0.
5178 * config/tc-mips.c (mips_align): Take new argument, label, and use
5179 it instead of global insn_label.
5180 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
5181 call to mips_emit_delay and pass it to mips_align.
5183 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5185 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

5199 version number. Delete all versions of temp files when finished
5200 with them. Create config.h.
5202 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
5203 values to reduce number of lookups with S_GET_VALUE. Skip debug
5204 symbols to avoid "a really nasty bug". (From Holger Teutsch,
5205 holger@botbso.rhein-main.de.)
5206 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
5207 field. (Also from Holger Teutsch.) Watch for a would-be register
5208 mask that spans frags.
5210 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
5211 this_base, not line_base. (Patch from Andreas Arens,

5215 look local if they're exported or undefined. Used to be done for
5218 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

7380 Add comments to functions. Delete unused functions, variables,
7381 #defines, etc. Delete unused members within structures. Delete
7382 ldil;ble hacks -- it is believed they were installed to work
7383 around old gas bugs. Avoid using mixed case for local
7384 functions, variables, and structures. Fix formatting problems
7385 not found by GNU-indent. Add FIXME notices for things which

8549 * Extensive changes to permit symbols to contain any expression
8550 type and to delay the computation of the expression until the
8551 value is actually needed. This permits setting symbols to values
8552 calculated based on object code size. Expressions were changed to
8553 no longer be in a section, to stop the overloading of segment and
8554 expression type that previously occurred.
8556 * as.c (big_section, pass1_section, diff_section, absent_section):
8558 (expr_section): Added (used for dummy symbols which hold

8642 (previous_section, previous_subsection): New vars.
8643 (obj_elf_section): Save current place in case DWARF code wants us
8644 to pop back to it. Handle unquoted section name as well as quoted
8645 section name. Don't crash on invalid strings.
8646 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
8649 * config/obj-elf.h: Don't include struc-symbol.h.

8667 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
8668 calculating opP->isiz; this permits the expression size to be
8669 determined as well, later on.

8683 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
8685 * read.c (float_cons): Simplified parsing logic. If
8686 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

8706 (macro): Call mips_emit_delays before setting mips_noreorder.
8707 Increment and decrement mips_noreorder rather than using

8734 (omagic): Removed unused variable.
8736 * Preliminary support for m88k-coff.

8755 * Removed sy_forward and replaced it with an undefined expression
8756 as the value of a symbol.
8757 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
8758 sy_resolved and sy_resolving single bit fields.
8759 * symbols.c (symbol_new): Don't initialize sy_forward field.
8760 (resolve_symbol_value): New function to adjust symbol value by
8761 fragment address, using recursion to resolve forward symbols.

8763 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
8764 expression rather than setting symbolP->sy_forward.
8765 * write.c (write_object_file): Use resolve_symbol_value on
8766 symbols, keeping the common case (the old behaviour) inline.

9793 than ECOFF line number information.
9794 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9879 source directory, if that's not the current directory.
9881 * configure.in (per-host): Accept MIPS host with BSD version

9902 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9903 process relocs if there aren't any relocs to process. Avoids
9904 malloc/free bug on SCO too.

9907 avoid some redefinition complaints on some systems.
9908 (const, volatile): Don't need these conditionally defined if we
9909 use CONST and VOLATILE from ansidecl.h.
9910 (seg_name): Use CONST, not const.
9912 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9914 * config/tc-mips.c: Reindented to GNU standards.
9916 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9918 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9919 (fixup_segment): Add a29k special case; the linker is not prepared
9920 to see a segment offset here.
9922 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9923 9 to only keep a space in between identifier characters.
9925 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9927 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9928 srcdir, might be in objdir.
9930 * doc/Makefile.in: dvi depends on as.dvi

9953 * Makefile.in (targ-cpu.o): Depend on config.h.
9955 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9957 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9958 dropping a space immediately following an identifier.
9959 * expr.c, write.c: Rewrote assert expressions to not use multiple
9960 lines; I don't think that can be done portably.
9961 * config/tc-mips.c (macro): Use $AT if target register is zero in
9962 load instruction, which it can be for a floating point load.
9964 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9972 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9975 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9976 z8k-opc.h, not z8k.h.
9978 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9981 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9983 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9985 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)

10036 prototypes for all static functions. Moved existing minimal
10037 debugging format support info #ifndef OBJ_ECOFF blocks.
10038 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
10039 does not support a non sign extended high 16 bits reloc. Adjusted

10086 * make-gas.com: Find obstack.obj if it's not in the current
10088 * read.c (s_ignore): Don't declare is_end_of_line. It's
10089 redundant, and triggers a VMS gcc compiler bug.
10091 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10092 current segment as an argument. (Ignored in all cases but VMS.)
10093 All callers and definitions changed.
10095 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
10097 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

10112 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
10113 Call elf_xstabs for .stabs and .xstabs operators.
10115 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
10117 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
10120 * configure.in: mips-bsd configuration was missing format spec.
10123 * Makefile.in (Makefile): Depends on configure.in.
10125 * config/tc-mips.c (append_insn): Don't check for alignment of
10126 frag in memory; alignment of instructions in section is a separate

10146 * config/tc-sparc.c (s_xword): Now call big_cons, so large
10147 constants are accepted, but symbolic values are not. GCC will not
10148 generate the latter currently.
10150 * frags.c (frag_init): New function.
10151 (zero_address_frag, bss_address_frag): Now initialized at run

10196 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
10197 (fixup_segment): Make sure common-section symbols get treated the
10198 same as undefined symbols.
10199 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

10202 * write.h (fix_new): Update prototype.
10204 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
10205 md_section_align, md_undefined_symbol): Don't provide prototypes
10206 if these are defined as macros.
10207 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

10403 * config/tc-sparc.c (architecture_requested, warn_on_bump,
10404 md_relax_table): Use default zero initialization.
10405 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

10418 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
10420 * expr.c (operand): If character other than comma or newline is a
10421 logical end-of-line character, use the newline case.
10422 From Eric Youngdale:
10423 (operand): Set X_add_number field for floating-point numbers.
10424 (operand): Treat zero byte as end-of-operand.
10426 * configure.in (per-target): Look for with_bfd_assembler option.
10427 For now, only accept "no", until the merge is done.
10429 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10430 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10431 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10432 * read.c: Finish conversion to S_* macros in the VMS only
10433 parts of the program. Add "const" modifier to hex_value.
10434 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10436 * expr.c: Add "const" modifier to hex_value.
10437 * symbols.c: Finish conversion to S_* macros in the VMS only
10438 parts of the program. Add "const" modifier to
10439 md_[long,short]_jump_size. Remove declaration of const_flag
10440 (which will be declared in obj-vms.h).
10441 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10442 Fix arguments to VMS_write_object_file.
10443 * config-gas.com: New file. Script for VMS systems to set up the
10444 configuration to build gas for VMS, and create config.status.
10445 * make-gas.com: Redone to work with new scheme.
10446 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10448 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10449 will swap bytes if needed on a big endian system. Use throughout
10451 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10452 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10453 types of malformed stabs. Change parsing algorithm so that we are
10454 more certain of having all of the information that we need on hand.
10455 * obj-vms.c (final_forward_reference): New function, used to help
10456 resolve the data types of as many struct elements as possible
10457 when some part of the struct is not fully defined by the compiler.
10458 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10460 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10461 as symbols as well in the object file. Look for external functions

10464 * tc-vax.c: Add '1' option for backward compatibility with older GCC
10466 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

10471 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10473 * read.c (s_data): Always use "data_section", since it'll map to
10474 SEG_DATA or SEG_E1 if needed.
10475 (s_lcomm): Likewise with bss_section.
10476 (s_fill): Use memset, not bzero.
10478 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10480 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10498 (seg_name): Declare only if not BFD_ASSEMBLER.
10499 (section_alignment): Declare only if not BFD_ASSEMBLER.
10500 (big_section, reg_section, pass1_section, diff_section,
10501 absent_section, text_section, data_section, bss_section): If
10502 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10503 mapping to segT enum values.
10504 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10505 if these are used or defined, if BFD_ASSEMBLER.
10506 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10507 subseg_new split into two functions.
10508 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10510 * as.h (volatile): Don't define if already defined.
10511 (had_errors, had_warnings): Provide prototypes for ANSI C even if

10514 declare with format attribute for -Wformat checking.
10516 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10518 * app.c, config/tc-*.c: Don't include read.h, since it is already

10522 <mtranle@paris.intellicorp.com>.
10523 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10524 obj_format coffbfd and gas_target i386coff for target.
10525 (i[34]86-*-isc*): New host (uses sysv).
10526 * config/i386aix.mt: Removed (no longer used).
10527 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10528 (MINUS_G): Removed.
10529 (LDFLAGS): Added, defined as -shlib.
10530 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10531 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10532 (DOT_LABEL_PREFIX): Define.
10533 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10534 name rather than L0\001.

10537 * symbols.c, symbols.h (local_bss_counter): Removed.
10538 * write.c (write_object_file): bss no longer uses
10539 local_bss_counter. Pass correct data and bss size to
10540 VMS_write_object_file.
10541 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10542 argument, rather than using local_bss_counter.

10546 (size_section): Restored sanity check.
10547 (do_relocs_for): Base section address on s_paddr rather than
10548 computing it. Adjust a29k R_IHIHALF special case to account for
10549 section paddr (used to require paddr to be zero). If there are no
10550 reclos, set s_relptr to 0. Set relocation size in object_headers.
10551 (fill_section): Always set s_vaddr here, removing
10552 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10553 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10554 Set STYP_INFO for .comment.
10555 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10556 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
10557 (crawl_symbols): Handle 8 character section name correctly. Use
10558 H_{SET,GET}_* macros.
10559 (do_linenos_for): Set lineno size in object_headers.
10560 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10561 set s_vaddr here. If string_byte_count remains 4, set it back to
10562 0, and only write strings out if there are some. Call
10563 fill_section before do_relocs_for and do_linenos_for.
10564 (obj_coff_section): Handle optional quoted second argument giving
10565 section characteristics.
10566 (obj_coff_bss): Added to handle .bss.
10567 (obj_coff_ident): Added to handle .ident (puts string in .comment

10587 (do_scrub_next_char): For \", return " not '.
10588 (symbol_chars): Now const.
10590 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10591 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10593 * config/obj-coff.h: Don't use #elif.
10595 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10596 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10598 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10600 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

10618 * Changes to support SCO 3.2v4:
10619 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10620 SEG_BSS, fill with NOP_OPCODE.
10621 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10622 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10623 using ZERO_BASED_SEGMENTS.
10624 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10625 never set segment address for SEG_E2 (.bss) and don't write out
10626 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10627 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10628 definitions, and don't merge tags with non-tags. Check for .bf
10629 rather than just checking whether the second character is b and
10630 the third character is f.
10631 (obj_coff_val): gcc can generate values which we don't handle
10632 correctly; discard information for now, since it only affects the
10633 debugging information.
10634 (tag_find_or_name): Don't insert tags in the symbol table.
10635 (yank_symbols): Don't merge labels.
10636 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10642 relative addends by the segment vaddr.
10643 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10644 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
10645 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

10786 z8000 documentation
10787 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10790 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10792 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10794 * subsegs.h: add extern to segment_info declaration.
10796 * read.h: added extern declarations for comment_chars,
10797 line_comment_chars, and line_separator_chars.
10798 read.c, app.c: removed definitions of comment_chars,
10799 line_comment_chars, and line_separator_chars.

10818 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10819 constant will not fit in an immediate field.

10822 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
10824 * obj-coff.c (callj_table): Delete global variable.
10825 (obj_emit_relocations): Define it locally here, and only if
10826 TC_I960 is defined.
10828 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10855 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
10857 * Support for i386-sysv.
10858 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10859 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10860 be used to set them all to zero as was done before.
10861 (fill_section): segment addresses now set in write_object_file.
10862 (fill_section): Don't set STYP_NOLOAD for .bss section.
10863 (fixup_segment): 386 uses strange common symbol format.

10898 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10900 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10901 #elif, since it is not supported by old compilers.
10902 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10903 couple of expressions in tc-m68k.c.
10905 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10907 * read.c (cons): If NO_RELOC is defined, use it.

10913 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10914 local labels to start with a .) and set REGISTER_PREFIX to %.
10915 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10917 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10919 * messages.c: Comment changes.
10921 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
10923 * as.h: Test if __STDC__ is defined only, don't test its value.
10924 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10926 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10928 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10931 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10933 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10934 sections starting from zero, rather than making them consecutive.
10935 This makes subsequent reloc calculations easier, esp if the object
10936 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10937 allocate lcomm in .data rather than in .bss. It seems that some
10938 tools can't cope with a non-zero sized bss before linkage.
10940 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10942 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10943 throughout. That enum no longer means what we thought it meant.
10945 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10946 "-mno-688[58]1" options.
10948 * tc-m68k.c: Added CPU32 support.
10950 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10952 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

10961 * Makefile.in (install): if $(tooldir) exists, install as in
10964 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10966 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10967 .word is < -32768 or > 32767. The -J flag causes the error to be
10968 ignored. This is to catch over-sized switches generated by gcc on
10969 systems which don't support the broken .word hack.
10970 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10971 write.c (fixup_segment): check for signed .word overflow if
10972 WARN_SIGNED_OVERFLOW_WORD.
10974 * write.c (fixup_segment): fixed missing parens in expression
10975 checking for byte or word overflow.
10977 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10978 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10979 WARN_SIGNED_OVERFLOW_WORD.
10981 * obj-coffbfd.c (fixup_segment): fixed missing parens in
10982 expression checking for byte or word overflow.

10991 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10993 * input-scrub.c (input_scrub_push): call input_file_begin, not
10995 messages.c (as_perror): print ": " between the passed in error and
10996 the strerror, like perror does.
10998 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

11005 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
11006 Motorola and MIT syntax; gas can now assemble either type of
11008 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
11009 From Steve Chamberlain:
11010 m68kcoff.mt: for m68k COFF.
11011 obj-coffbfd.c: (fixup_mdeps) added
11012 (size_section) removed bad sanity check
11013 (fill_section) added rs_machine_dependent case
11014 (write_object_file) call fixup_mdeps
11015 (fixup_segment) set fx_subsy to 0.
11016 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
11018 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
11021 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

11045 tc-i960.c (md_ri_to_chars): Always output bout object file in
11046 little endian byte order (used to use endianness of host).
11048 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11050 * config/tc-m68k.c (init_table): Now const. Always include 68851
11051 data, so that "bc" is available to 68040 cache instructions.
11052 Added "tt0", "tt1", and 68ec030 variants.
11053 (md_assemble): Complain if 68000 (only) and 68881 are specified.
11054 (enum _register): Added TT0, TT1.
11055 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
11056 line number correctly in "internal error" messages. Don't print
11057 architecture-mismatch message for operand errors.
11059 From Colin Smith (colin@wrs.com):
11060 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
11061 than install_operand.
11063 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
11065 * listing.c (buffer_line): rewind to the start of include
11066 files, they might be included twice.
11068 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
11070 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
11072 * Makefile.in: defined TARGET_CPU for C code so that it can choose
11073 one element of a family.
11075 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
11077 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
11078 so that we can assemble hand-written libgcc code.
11080 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
11082 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
11083 has already been formatted (but may still contain %-characters).
11084 (as_bad): Likewise.
11086 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
11088 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
11089 written with indirection on the last two operands, which can be
11090 either data or address registers. Added a new operand type 'r'
11091 which accepts either register type. Added '(' to notend stuff in
11092 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
11094 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
11096 * as.h (enum _relax_state): Start off at one, not zero, to better
11097 catch uninitialized-variable errors.
11098 (linkrelax): Declare new variable.
11100 * messages.c (warning_count, error_count): Default initializer is
11103 * write.c: Merged some declarations, using PARMS macro.

11105 data_last_frag): No longer static.
11106 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
11107 defined, call it. Change segments before calling fixup_segment.
11108 (relax_align): If linkrelax, provide extra padding.
11110 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
11111 their not having symbols associated.
11113 * tc-i960.c (norelax, instrument_branches): Default initializer is
11115 (linkrelax): Delete variable definition.

11204 characteristics have been), default to 68020. Don't need extra
11205 quotes around error string.

11341 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
11343 * Makefile.in (install): Install into $(tooldir)/bin, since that's
11344 where gcc looks for it.
11346 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
11348 * Makefile.in: Changed some lines to be less confusing for some

11388 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
11390 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

11414 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
11416 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
11418 * expr.c (operand): if can't work out what sort of operand it is,
11419 then look through FLT_CHARS for a hint.
11421 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11423 * Makefile.in, configure.in: removed traces of namesubdir,
11424 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11425 copyrights to '92, changed some from Cygnus to FSF.
11427 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11428 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11429 copyrights to '92, changed some from Cygnus to FSF.
11431 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11433 * expr.c: If an expression is single comma, then return with
11434 SEG_ABSENT rather than an error - since the sparc front end does
11435 really strange things with things like fbge,a
11437 * as.h: include bfd.h if using many sections
11438 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11439 local labels didn't work.
11440 * listing.c (list_symbol_table): don't core dump when there's no
11442 * write.c, write.h: call fix_new with the right number of args on
11444 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11447 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11449 * app.c: MRI compatibility - allow single quote to start a string.
11450 * as.c: fix typo recently introduced.
11451 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11452 * expr.c: Much rewriting, to accomodate MRI syntax for
11453 expressions. Also easier to read now.
11454 * listing.c: Put back defuns
11455 * read.c: modified to accept MRI syntax, put back listing pseudo
11456 ops so that an assembler built with NO_LISTING ignores list ops
11458 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11459 machine is a SPARC or a 29K.
11460 * config/obj-aout.c: added s_sect pseudo op
11461 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11462 fill in the timestamp.
11463 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11464 anymore, define all the relocs which the tc-<x> bit will use so we
11465 can translate from them to the coff types.
11466 * config/tc-a29k.c: reloc_type isn't ane enum any more
11467 * config/tc-m68k.c: Added NO_RELOC definition.
11469 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11471 * Makefile.in: put header files before C source for TAGS; remove
11472 references to non-existent syscalls.h.
11474 * read.c, write.c subsegs.c: back out the .bss changes.
11476 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11478 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11480 * a.out.h: removed.
11482 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11484 * symbols.c (local_label_name): symbols now start with ^A.
11486 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11487 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11488 generate these sections. .align: will use NOP_OPCODE or 0
11489 for padding. This is just for being nice to the
11492 * expr.c (operand): changed to generate local label "\001L0"
11493 starting with a ^A so that it is recognized as a local label.
11495 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11497 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11498 i/o opcodes - inb, inw, outb and outw. string manipulation with
11499 att syntax - scmp, slod, smov, ssca, ssto.
11501 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11502 to just after .file .
11504 In obj_crawl_symbol_chain() where it tries to put the external
11505 symbols apart, with the condition:
11506 (!S_IS_DEFINED(symbolP) &&
11507 !S_IS_DEBUG(symbolP) &&
11508 !SF_GET_STATICS(symbolP))
11509 it was moving too many symbols out. So I switch it back to the
11511 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11513 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11514 so that we don't use the F_RELFLG which make the linker complain
11515 that somebody has stripped the relocation info.
11517 Also, the AIX ld program require that the relocation table
11518 is sorted by r_vaddr like the standard ATT assembler does.
11520 [he also changed the sizeof(struct ...)'s into the coff
11521 style FOOSZ macros. I'm not sure this is right, but I can't
11522 remember why. xoxorich.]
11524 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11526 * Makefile.in, configure.in, doc: use the doc. Build it, install
11529 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11531 * read.c: white space and comments only.
11533 * configure.in: use the new atof-ns32.c for ns32k.
11535 * write.c: comment change only.
11537 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11538 aren't yet integrated.
11540 * tc-i860.[hc]: blew off the dust. Something must still be done
11541 about conflicting relocation types.
11543 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11546 * tc-i960.c, tc-sparc.c: white space and comments only.
11548 * tc-a29k.h: delete duplicate macro definition.
11550 * new file atof-ns32k.c copied from hack's last unreleased gas.
11552 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11554 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11557 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11558 ChangeLog's prior to this are sketchy at best. I have logs.
11559 They just aren't ChangeLogs.
