143 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
144 do include the optional header for Apollo target.
145 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
147 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
148 can be used within a label name.

174 * listing.c (list_symbol_table): Don't print register symbols as
177 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip

181 * as.c (main): If tc_init_after_args is defined, invoke it after
182 all arguments have been processed.

259 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
261 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

264 source files from other directories into objects in the current
265 directory, and specify PSECT attributes explicitly to linker.
266 Also added missing label.
267 * Makefile.in (stamp-mk.com): Reference new variable
268 VMS_OTHER_OBJS for list of non-local object files, instead of

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

418 to make it pcrel_offset.
419 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

433 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
434 tested by code that might want to emit a LITUSE reloc.
435 (emit_unaligned_io): New function. Currently calls md_assemble,
436 but it should eventually be converted to generate the insn itself
437 and call emit_insn directly.

451 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
452 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

472 -non_shared to use NO_PIC (this is how the Irix 5 assembler
473 works). Do not permit -G with SVR4_PIC.

477 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
479 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
481 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

487 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
489 * Makefile.in (config-stamp): If `defs' is defined, emit a
490 preprocessor directive to create a macro named by this value into
491 config.new; don't explicitly go for BFD_ASSEMBLER.
492 * configure.in: Define `defs', not `BFDDEF'. Set it to
493 MANY_SEGMENTS for any obj-coffbfd target.
494 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
495 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
497 (LOCAL_LOADLIBES): Deleted.
498 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
499 * config/m88kcoff.mt (TDEFINES): Ditto.
500 * config/ebmon29k.mt: Deleted.
501 * config/h8300hds.mt: Deleted.
502 * config/ic960coff.mt: Deleted.
503 * config/sparc.mt: Deleted.

525 bfd_set_symtab is called.
526 (dump_section_relocs): Note whether a symbol is a section symbol
528 (adjust_reloc_syms): For now, always supply an absolute symbol for
529 fixups without symbols but not yet `done'. Use section_symbol to
530 get the symbol, instead of going directly for abs_symbol.
531 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
532 reloc is not a section symbol and is not in the symbol table.
533 (set_symtab): New function, broken out from write_object_file.
534 Counts symbol table instead of relying on an earlier count.
535 (write_object_file): Call set_symtab, but do it after potentially
536 invoking the *_frob_file macros. Don't bother counting symbols.
537 Call symbol_remove, instead of expanding it in place. Moved the
538 conditionalized `object_file_size' declaration down to
539 conditionalized block where it's used. When using the absolute
540 symbol for a fixup without a symbol, set sy_used_in_reloc.
541 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
542 the correct symbol for the absolute section.
544 * subsegs.c (section_symbol): Use symbol_new instead of
545 symbol_make, since we may want it to go into the symbol table.
546 Make the new symbol have internal linkage. If
547 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
548 symbol with the newly created GAS symbol.
549 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
550 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

555 (in_signed_range): New function.
557 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
558 (sparc_ip, label "immediate"): Reject constants for pcrel
559 instructions only if the relocation type indicates a "call"
560 instruction and the offset is within range of a "jmpl %g0". If
561 it's not in range, use the absolute section symbol plus an offset.
562 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
564 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
566 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
569 * configure.in: Eliminated all targets using obj-coff but not
570 defining BFD_ASSEMBLER; I think all such targets that are
571 supported will be matched by real CPU-OS combinations earlier in
573 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
574 some comments about the dpx2 configuration, but left it disabled,
575 since it couldn't be reached before.
576 (target a29k-amd-ebmonold): Deleted.
578 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

586 the 'j' operand if there are no further alternatives for this
589 * config/obj-coffbfd.c (adjust_stab_section): Initialize
590 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
591 is not SEG_UNKNOWN rather than checking whether it is >= 0.
593 * config/tc-mips.c (mips_align): Take new argument, label, and use
594 it instead of global insn_label.
595 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
596 call to mips_emit_delay and pass it to mips_align.
598 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
600 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
602 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
603 argument to a .callinfo directive. Don't loop forever on errors.
605 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
606 use pre-defined registers as arguments.
608 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
610 * write.c (write_object_file): Check both S_IS_LOCAL and
611 S_IS_EXTERNAL when deciding whether to discard a symbol.
613 * config-gas.com: Scan Makefile.in, not version.c, for current
614 version number. Delete all versions of temp files when finished
615 with them. Create config.h.
617 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
618 values to reduce number of lookups with S_GET_VALUE. Skip debug
619 symbols to avoid "a really nasty bug". (From Holger Teutsch,
620 holger@botbso.rhein-main.de.)
621 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
622 field. (Also from Holger Teutsch.) Watch for a would-be register
623 mask that spans frags.
625 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
626 this_base, not line_base. (Patch from Andreas Arens,
627 ari@obelix.av.rwth-aachen.de.)
629 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
630 look local if they're exported or undefined. Used to be done for
633 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

635 the input stream, which is no longer null-terminated.
636 (LEX_PCT): New macro, defaults to 0.
637 (lex_type): Use it for `%'.
639 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
640 (vip_op): Now static, and returns void. Callers changed. Added
642 (vip): Ditto. Call as_fatal directly if a program bug is

2420 pass new argument for i, j and o cases.
2421 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2423 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
2424 rather than hard coded constants.
2425 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2642 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2643 the table, require that the one without bit 0x1000000 set come

2755 for keeping or rejecting configurations still under development;
2756 default is to assume production environment, and reject configs
2757 still being worked on. Mark Elf configurations (except sparc and
2758 i386) as developmental. Deleted cases matching some generic names
2759 in favor of more specific names. (E.g., when we get Alpha
2760 support, we'll still only support VMS for Vax.)

2774 against placing additional object-file dependent code here. Warn
2775 against contaminating all of GAS with the internals of tc-hppa.c
2776 through inclusion of tc-hppa.h. Delete all forward declarations
2777 for functions only used within tc-hppa.c, likewise for structures,
2778 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2779 conditional code in a few small places.
2781 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2782 structures, global variables, forward declarations together.

2785 into a few places. Make all functions and variables which
2786 are only used within tc-hppa.c static. PARAMize all functions.
2787 Add comments to functions. Delete unused functions, variables,
2788 #defines, etc. Delete unused members within structures. Delete
2789 ldil;ble hacks -- it is believed they were installed to work
2790 around old gas bugs. Avoid using mixed case for local
2791 functions, variables, and structures. Fix formatting problems
2792 not found by GNU-indent. Add FIXME notices for things which
2793 should be worked on the near future. Delete lots of old
2794 useless (1.36 PA-SOM) code.
2796 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2797 field of the fixS structure. Needed to build unwind

2826 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2827 bits are zero (eg they specify no relocations), then do not even
2828 bother adding their entries to thesymextn section.

3937 * Extensive changes to permit symbols to contain any expression
3938 type and to delay the computation of the expression until the
3939 value is actually needed. This permits setting symbols to values
3940 calculated based on object code size. Expressions were changed to
3941 no longer be in a section, to stop the overloading of segment and
3942 expression type that previously occurred.
3944 * as.c (big_section, pass1_section, diff_section, absent_section):
3946 (expr_section): Added (used for dummy symbols which hold

4143 * Removed sy_forward and replaced it with an undefined expression
4144 as the value of a symbol.

4146 sy_resolved and sy_resolving single bit fields.
4147 * symbols.c (symbol_new): Don't initialize sy_forward field.

4151 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
4152 expression rather than setting symbolP->sy_forward.

5150 than ECOFF line number information.
5151 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5183 * doc/as.texinfo: First pass at using new texinfo features --
5184 variables, conditional tests. Far from complete.

5212 dependencies are read, not when they are used).
5214 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5215 a29k .bss section; the mondfe program doesn't like it.

5236 source directory, if that's not the current directory.
5238 * configure.in (per-host): Accept MIPS host with BSD version

5260 process relocs if there aren't any relocs to process. Avoids
5261 malloc/free bug on SCO too.
5263 * as.h: Move local include files below system include files, to
5264 avoid some redefinition complaints on some systems.
5265 (const, volatile): Don't need these conditionally defined if we
5266 use CONST and VOLATILE from ansidecl.h.
5267 (seg_name): Use CONST, not const.
5269 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5271 * config/tc-mips.c: Reindented to GNU standards.

5275 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5276 (fixup_segment): Add a29k special case; the linker is not prepared
5277 to see a segment offset here.
5279 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5282 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5284 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5300 bignums, but don't emit error message.
5302 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5304 * Makefile.in (targ-cpu.o): Depend on config.h.
5306 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5308 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5309 dropping a space immediately following an identifier.
5310 * expr.c, write.c: Rewrote assert expressions to not use multiple
5311 lines; I don't think that can be done portably.
5312 * config/tc-mips.c (macro): Use $AT if target register is zero in
5313 load instruction, which it can be for a floating point load.
5315 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5336 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5338 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5339 to be on a single line.
5341 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5386 * config/tc-mips.c: Rearranged for ECOFF support. Added
5387 prototypes for all static functions. Moved existing minimal
5388 debugging format support info #ifndef OBJ_ECOFF blocks.
5389 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
5390 does not support a non sign extended high 16 bits reloc. Adjusted
5391 all callers accordingly.
5392 (tc_get_register): Renamed from get_register, and made non-static.
5394 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5437 * make-gas.com: Find obstack.obj if it's not in the current
5439 * read.c (s_ignore): Don't declare is_end_of_line. It's
5440 redundant, and triggers a VMS gcc compiler bug.
5442 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5443 current segment as an argument. (Ignored in all cases but VMS.)
5444 All callers and definitions changed.

5741 md_relax_table): Use default zero initialization.
5742 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5743 latter, instead of selecting with preprocessor conditionals.
5745 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5747 * configure.in: recognise all sparclite variants

5757 * expr.c (operand): If character other than comma or newline is a
5758 logical end-of-line character, use the newline case.
5759 From Eric Youngdale:
5760 (operand): Set X_add_number field for floating-point numbers.
5761 (operand): Treat zero byte as end-of-operand.
5763 * configure.in (per-target): Look for with_bfd_assembler option.
5764 For now, only accept "no", until the merge is done.
5766 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5767 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5773 * expr.c: Add "const" modifier to hex_value.
5774 * symbols.c: Finish conversion to S_* macros in the VMS only
5775 parts of the program. Add "const" modifier to
5776 md_[long,short]_jump_size. Remove declaration of const_flag
5777 (which will be declared in obj-vms.h).
5778 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5779 Fix arguments to VMS_write_object_file.
5780 * config-gas.com: New file. Script for VMS systems to set up the
5781 configuration to build gas for VMS, and create config.status.
5782 * make-gas.com: Redone to work with new scheme.
5783 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5785 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5786 will swap bytes if needed on a big endian system. Use throughout
5788 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5789 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5790 types of malformed stabs. Change parsing algorithm so that we are
5791 more certain of having all of the information that we need on hand.
5792 * obj-vms.c (final_forward_reference): New function, used to help
5793 resolve the data types of as many struct elements as possible
5794 when some part of the struct is not fully defined by the compiler.

5797 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5798 as symbols as well in the object file. Look for external functions
5799 that start with "__vt.", and turn them into variables, since the
5800 g++ compiler is incapable of doing this.
5801 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5803 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5804 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5805 have the name of the source file yet.
5806 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5808 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5810 * read.c (s_data): Always use "data_section", since it'll map to
5811 SEG_DATA or SEG_E1 if needed.
5812 (s_lcomm): Likewise with bss_section.
5813 (s_fill): Use memset, not bzero.
5815 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5836 (section_alignment): Declare only if not BFD_ASSEMBLER.
5837 (big_section, reg_section, pass1_section, diff_section,
5838 absent_section, text_section, data_section, bss_section): If
5839 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5840 mapping to segT enum values.
5841 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5842 if these are used or defined, if BFD_ASSEMBLER.
5843 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5844 subseg_new split into two functions.
5845 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5847 * as.h (volatile): Don't define if already defined.
5848 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5850 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5851 declare with format attribute for -Wformat checking.
5853 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5855 * app.c, config/tc-*.c: Don't include read.h, since it is already
5858 * These are based on patches from Minh Tran-le
5859 <mtranle@paris.intellicorp.com>.
5860 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5861 obj_format coffbfd and gas_target i386coff for target.
5862 (i[34]86-*-isc*): New host (uses sysv).
5863 * config/i386aix.mt: Removed (no longer used).
5864 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5866 (LDFLAGS): Added, defined as -shlib.
5867 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5868 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5869 (DOT_LABEL_PREFIX): Define.
5870 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5871 name rather than L0\001.
5872 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5874 * symbols.c, symbols.h (local_bss_counter): Removed.
5875 * write.c (write_object_file): bss no longer uses
5876 local_bss_counter. Pass correct data and bss size to
5877 VMS_write_object_file.

5883 (size_section): Restored sanity check.
5884 (do_relocs_for): Base section address on s_paddr rather than
5885 computing it. Adjust a29k R_IHIHALF special case to account for
5886 section paddr (used to require paddr to be zero). If there are no
5887 reclos, set s_relptr to 0. Set relocation size in object_headers.
5888 (fill_section): Always set s_vaddr here, removing
5889 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5890 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5891 Set STYP_INFO for .comment.
5892 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5893 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5895 H_{SET,GET}_* macros.
5896 (do_linenos_for): Set lineno size in object_headers.
5897 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5898 set s_vaddr here. If string_byte_count remains 4, set it back to
5899 0, and only write strings out if there are some. Call
5900 fill_section before do_relocs_for and do_linenos_for.
5901 (obj_coff_section): Handle optional quoted second argument giving
5902 section characteristics.
5903 (obj_coff_bss): Added to handle .bss.
5904 (obj_coff_ident): Added to handle .ident (puts string in .comment
5906 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5907 (fixup_mdeps): Change to segment. Call frag_wane after

5924 (do_scrub_next_char): For \", return " not '.
5925 (symbol_chars): Now const.
5927 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5928 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5930 * config/obj-coff.h: Don't use #elif.
5932 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5933 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5935 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5937 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5959 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5960 using ZERO_BASED_SEGMENTS.
5961 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5962 never set segment address for SEG_E2 (.bss) and don't write out
5963 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5964 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5965 definitions, and don't merge tags with non-tags. Check for .bf
5966 rather than just checking whether the second character is b and
5967 the third character is f.
5968 (obj_coff_val): gcc can generate values which we don't handle
5969 correctly; discard information for now, since it only affects the
5970 debugging information.
5971 (tag_find_or_name): Don't insert tags in the symbol table.
5972 (yank_symbols): Don't merge labels.
5973 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6112 GNU `indent'. Some cleanup still needed, especially of comments.
6114 * configure.in: No te-386bsd.h file exists; don't try to use it.
6116 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6118 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6119 could be doing emulation.
6121 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6124 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6151 consistently const, and always initialized them. Included read.h.
6153 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6155 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6156 constant will not fit in an immediate field.
6157 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6159 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6161 * obj-coff.c (callj_table): Delete global variable.

6176 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6177 so widening works consistently.
6179 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6181 * version.c: Put conditional "const" before version_string, not
6182 before dummy function for VMS. Now version 1.91.03.
6184 * app.c (do_scrub_next_char): Need double-\ before `000' to show
6185 printed rep of null character.
6187 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
6189 * obj-coffbfd.c (write_object_file): check return value of
6192 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6194 * Support for i386-sysv.
6195 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6196 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6197 be used to set them all to zero as was done before.
6198 (fill_section): segment addresses now set in write_object_file.
6199 (fill_section): Don't set STYP_NOLOAD for .bss section.
6200 (fixup_segment): 386 uses strange common symbol format.
6201 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
6202 compatibility with SVR3.2 linker.
6203 * configure.in: i386-sysv and i386-sco use coffbfd.
6205 * app.c (do_scrub_next_char): discard whitespace after a label.

6214 fix i960+non-bfd coff bit rot.
6215 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6216 support for C source listings. (obj_coff_endef): look in the right
6217 part of the symbol for the symbol name
6219 * tc-m68k.c (get_num): make it work for all segments, not just the
6222 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6224 * configure.in: recognize i386-*-bsd emulation.

6233 * tc-z8k.c: lots of bug fixes
6235 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6237 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6238 #elif, since it is not supported by old compilers.
6239 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6240 couple of expressions in tc-m68k.c.
6242 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6244 * read.c (cons): If NO_RELOC is defined, use it.
6246 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6248 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6250 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6251 local labels to start with a .) and set REGISTER_PREFIX to %.
6252 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6254 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6268 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6270 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6271 sections starting from zero, rather than making them consecutive.
6272 This makes subsequent reloc calculations easier, esp if the object
6273 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6274 allocate lcomm in .data rather than in .bss. It seems that some
6275 tools can't cope with a non-zero sized bss before linkage.
6277 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6279 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6280 throughout. That enum no longer means what we thought it meant.

6296 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6298 * Makefile.in (install): if $(tooldir) exists, install as in
6301 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6303 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6304 .word is < -32768 or > 32767. The -J flag causes the error to be
6305 ignored. This is to catch over-sized switches generated by gcc on
6306 systems which don't support the broken .word hack.
6307 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6308 write.c (fixup_segment): check for signed .word overflow if
6309 WARN_SIGNED_OVERFLOW_WORD.
6311 * write.c (fixup_segment): fixed missing parens in expression
6312 checking for byte or word overflow.
6314 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6326 * tc-i386.h : new coff defines
6328 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6330 * input-scrub.c (input_scrub_push): call input_file_begin, not
6332 messages.c (as_perror): print ": " between the passed in error and
6333 the strerror, like perror does.
6335 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6337 * Makefile.in: use gas_target instead of modifying target_cpu.
6338 From Steve Chamberlain:
6339 Makefile.in: Handle m68*-*-coff*.
6340 read.c, read.h: add mult argument to s_space
6342 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6343 Motorola and MIT syntax; gas can now assemble either type of
6345 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6346 From Steve Chamberlain:
6347 m68kcoff.mt: for m68k COFF.
6348 obj-coffbfd.c: (fixup_mdeps) added

6351 (write_object_file) call fixup_mdeps
6352 (fixup_segment) set fx_subsy to 0.
6353 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6355 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6358 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6360 * Makefile.in (LIBS): Include opcode library.
6362 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6382 tc-i960.c (md_ri_to_chars): Always output bout object file in
6383 little endian byte order (used to use endianness of host).
6385 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6387 * config/tc-m68k.c (init_table): Now const. Always include 68851
6388 data, so that "bc" is available to 68040 cache instructions.
6389 Added "tt0", "tt1", and 68ec030 variants.
6390 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6391 (enum _register): Added TT0, TT1.
6392 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6393 line number correctly in "internal error" messages. Don't print
6394 architecture-mismatch message for operand errors.
6396 From Colin Smith (colin@wrs.com):
6397 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6398 than install_operand.

6402 * listing.c (buffer_line): rewind to the start of include
6403 files, they might be included twice.

6410 one element of a family.
6412 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6414 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6415 so that we can assemble hand-written libgcc code.
6417 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6419 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6420 has already been formatted (but may still contain %-characters).
6423 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6425 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6426 written with indirection on the last two operands, which can be
6427 either data or address registers. Added a new operand type 'r'
6428 which accepts either register type. Added '(' to notend stuff in
6429 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6431 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6447 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6448 their not having symbols associated.
6450 * tc-i960.c (norelax, instrument_branches): Default initializer is
6452 (linkrelax): Delete variable definition.

6475 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6476 being used with args swapped, causing occasional lossage when
6477 refilling buffers after an include file.
6479 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6481 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6482 version. Discard bogus DONTDEF version.
6483 (as_warn, as_bad, as_fatal): Likewise.
6485 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6487 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6488 selected architecture, print a message saying so and listing what

6510 * read.c (s_fill): make the .fill size clamped error a warn and
6511 fix bug where 0's were always placed.
6513 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6514 two bytes of any constant with 0xff:

6533 * configure.in (mips host): Accept "ultrix" with version number.
6535 * expr.c (floating_constant): Separate "=-" to avoid confusing
6536 ancient or broken compilers.
6538 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6539 processor/opcode mismatch, so reword the error message.
6540 (md_assemble): If no CPU has been set (even if FPU/PMMU
6541 characteristics have been), default to 68020. Don't need extra
6542 quotes around error string.
6544 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6546 * read.c (potable): Revert sac's incorrect change made Jul 13.

6620 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
6621 rather than use ugly if tree. (init_regtable): insert register
6622 names into symbol table.
6624 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6626 * write.c (write_object_file): keep the fix_tail clean, which
6627 fixes a bug in -R where relocations were being lost.
6629 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6631 * configure.in: recognize m680x0 as having sun3 emulation mode for

6654 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6656 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
6657 calc the base of relocs correctly.
6658 * tc-a29k.c (parse_operand): allow expressions to be in any section.
6660 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
6662 * as.c, write.c: use -K rather than -k for the broken word warning

6675 * write.c (write_object_file): For b.out format, round up section
6676 start addresses to match required alignment.
6678 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6680 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6681 where gcc looks for it.
6683 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6685 * Makefile.in: Changed some lines to be less confusing for some

6725 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6727 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

6751 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6753 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6755 * expr.c (operand): if can't work out what sort of operand it is,
6756 then look through FLT_CHARS for a hint.
6758 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6760 * Makefile.in, configure.in: removed traces of namesubdir,
6761 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6762 copyrights to '92, changed some from Cygnus to FSF.
6764 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6765 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6766 copyrights to '92, changed some from Cygnus to FSF.
6768 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6770 * expr.c: If an expression is single comma, then return with
6771 SEG_ABSENT rather than an error - since the sparc front end does
6772 really strange things with things like fbge,a
6774 * as.h: include bfd.h if using many sections
6775 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6776 local labels didn't work.
6777 * listing.c (list_symbol_table): don't core dump when there's no
6779 * write.c, write.h: call fix_new with the right number of args on
6781 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6784 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6786 * app.c: MRI compatibility - allow single quote to start a string.
6787 * as.c: fix typo recently introduced.
6788 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6789 * expr.c: Much rewriting, to accomodate MRI syntax for
6790 expressions. Also easier to read now.
6791 * listing.c: Put back defuns
6792 * read.c: modified to accept MRI syntax, put back listing pseudo
6793 ops so that an assembler built with NO_LISTING ignores list ops
6795 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6796 machine is a SPARC or a 29K.
6797 * config/obj-aout.c: added s_sect pseudo op
6798 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6799 fill in the timestamp.
6800 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6801 anymore, define all the relocs which the tc-<x> bit will use so we
6802 can translate from them to the coff types.
6803 * config/tc-a29k.c: reloc_type isn't ane enum any more
6804 * config/tc-m68k.c: Added NO_RELOC definition.
6806 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6808 * Makefile.in: put header files before C source for TAGS; remove
6809 references to non-existent syscalls.h.
6811 * read.c, write.c subsegs.c: back out the .bss changes.
6813 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6815 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6819 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6821 * symbols.c (local_label_name): symbols now start with ^A.
6823 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6824 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6825 generate these sections. .align: will use NOP_OPCODE or 0
6826 for padding. This is just for being nice to the
6829 * expr.c (operand): changed to generate local label "\001L0"
6830 starting with a ^A so that it is recognized as a local label.
6832 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6834 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6835 i/o opcodes - inb, inw, outb and outw. string manipulation with
6836 att syntax - scmp, slod, smov, ssca, ssto.
6838 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6839 to just after .file .
6841 In obj_crawl_symbol_chain() where it tries to put the external
6842 symbols apart, with the condition:
6843 (!S_IS_DEFINED(symbolP) &&
6844 !S_IS_DEBUG(symbolP) &&
6845 !SF_GET_STATICS(symbolP))
6846 it was moving too many symbols out. So I switch it back to the
6848 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6850 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6851 so that we don't use the F_RELFLG which make the linker complain
6852 that somebody has stripped the relocation info.
6854 Also, the AIX ld program require that the relocation table
6855 is sorted by r_vaddr like the standard ATT assembler does.
6857 [he also changed the sizeof(struct ...)'s into the coff
6858 style FOOSZ macros. I'm not sure this is right, but I can't
6859 remember why. xoxorich.]
6861 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6863 * Makefile.in, configure.in, doc: use the doc. Build it, install

6868 * read.c: white space and comments only.
6870 * configure.in: use the new atof-ns32.c for ns32k.
6872 * write.c: comment change only.
6874 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6875 aren't yet integrated.
6877 * tc-i860.[hc]: blew off the dust. Something must still be done
6878 about conflicting relocation types.
6880 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6883 * tc-i960.c, tc-sparc.c: white space and comments only.
6885 * tc-a29k.h: delete duplicate macro definition.
6887 * new file atof-ns32k.c copied from hack's last unreleased gas.
6889 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6891 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6894 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6895 ChangeLog's prior to this are sketchy at best. I have logs.
6896 They just aren't ChangeLogs.
6900 version-control: never
