492 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
493 branch with an instruction that uses $at, in case the branch is
495 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
496 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
497 to make it pcrel_offset.
498 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
499 reloc->address; another gruesome hack to get gas reloc handling to
502 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
504 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
507 (emit_insn): New function.
508 (md_assemble): Call it.
509 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
511 (lituse_pending): New variable. Set by anything that generates a
512 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
513 tested by code that might want to emit a LITUSE reloc.
514 (emit_unaligned_io): New function. Currently calls md_assemble,
515 but it should eventually be converted to generate the insn itself
516 and call emit_insn directly.
517 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
518 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
519 emit_bis_r): Likewise.
520 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
521 (alpha_ip, label get_macro): Don't emit the final instruction if
523 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
524 unaligned memory access macros.

526 the value can't be resolved.
528 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
530 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
531 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
532 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
534 (mips_force_relocation): New function.
535 (md_apply_fix): Set fixP->fx_done appropriately.
536 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

544 * config/tc-mips.c (enum mips_pic_level): New enum.
545 (mips_pic): Change from int to enum mips_pic_level. Change all
546 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
547 (load_address): Handle EMBEDDED_PIC.
548 (macro): Handle EMBEDDED_PIC in all PIC cases.
549 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
550 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
551 -non_shared to use NO_PIC (this is how the Irix 5 assembler
552 works). Do not permit -G with SVR4_PIC.
553 (s_abicalls): Warn if -G was used, and force -G 0.
554 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
555 anything but a.out, not just for ELF. For ECOFF, don't generate a
556 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
558 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
560 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

566 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
568 * Makefile.in (config-stamp): If `defs' is defined, emit a
569 preprocessor directive to create a macro named by this value into
570 config.new; don't explicitly go for BFD_ASSEMBLER.
571 * configure.in: Define `defs', not `BFDDEF'. Set it to
572 MANY_SEGMENTS for any obj-coffbfd target.
573 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
574 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
576 (LOCAL_LOADLIBES): Deleted.
577 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
578 * config/m88kcoff.mt (TDEFINES): Ditto.

604 bfd_set_symtab is called.
605 (dump_section_relocs): Note whether a symbol is a section symbol
607 (adjust_reloc_syms): For now, always supply an absolute symbol for
608 fixups without symbols but not yet `done'. Use section_symbol to
609 get the symbol, instead of going directly for abs_symbol.
610 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
611 reloc is not a section symbol and is not in the symbol table.
612 (set_symtab): New function, broken out from write_object_file.
613 Counts symbol table instead of relying on an earlier count.
614 (write_object_file): Call set_symtab, but do it after potentially
615 invoking the *_frob_file macros. Don't bother counting symbols.
616 Call symbol_remove, instead of expanding it in place. Moved the
617 conditionalized `object_file_size' declaration down to
618 conditionalized block where it's used. When using the absolute
619 symbol for a fixup without a symbol, set sy_used_in_reloc.
620 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
621 the correct symbol for the absolute section.
623 * subsegs.c (section_symbol): Use symbol_new instead of
624 symbol_make, since we may want it to go into the symbol table.
625 Make the new symbol have internal linkage. If
626 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
627 symbol with the newly created GAS symbol.
628 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
629 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

634 (in_signed_range): New function.
636 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
637 (sparc_ip, label "immediate"): Reject constants for pcrel
638 instructions only if the relocation type indicates a "call"
639 instruction and the offset is within range of a "jmpl %g0". If
640 it's not in range, use the absolute section symbol plus an offset.
641 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
643 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
645 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
648 * configure.in: Eliminated all targets using obj-coff but not
649 defining BFD_ASSEMBLER; I think all such targets that are
650 supported will be matched by real CPU-OS combinations earlier in
652 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
653 some comments about the dpx2 configuration, but left it disabled,
654 since it couldn't be reached before.
655 (target a29k-amd-ebmonold): Deleted.
657 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
659 * config/tc-hppa.c (pa_import): Correctly handle importing of an
660 already defined symbol.

665 the 'j' operand if there are no further alternatives for this
668 * config/obj-coffbfd.c (adjust_stab_section): Initialize
669 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
670 is not SEG_UNKNOWN rather than checking whether it is >= 0.
672 * config/tc-mips.c (mips_align): Take new argument, label, and use
673 it instead of global insn_label.
674 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
675 call to mips_emit_delay and pass it to mips_align.
677 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
679 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
681 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
682 argument to a .callinfo directive. Don't loop forever on errors.
684 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
685 use pre-defined registers as arguments.
687 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
689 * write.c (write_object_file): Check both S_IS_LOCAL and
690 S_IS_EXTERNAL when deciding whether to discard a symbol.
692 * config-gas.com: Scan Makefile.in, not version.c, for current
693 version number. Delete all versions of temp files when finished
694 with them. Create config.h.
696 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
697 values to reduce number of lookups with S_GET_VALUE. Skip debug

699 holger@botbso.rhein-main.de.)
700 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
701 field. (Also from Holger Teutsch.) Watch for a would-be register
702 mask that spans frags.
704 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
705 this_base, not line_base. (Patch from Andreas Arens,
706 ari@obelix.av.rwth-aachen.de.)
708 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
709 look local if they're exported or undefined. Used to be done for
712 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
713 Get it from the looked-up symbol, instead of using the string from
714 the input stream, which is no longer null-terminated.

716 (lex_type): Use it for `%'.
718 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
719 (vip_op): Now static, and returns void. Callers changed. Added

780 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
781 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2837 i386) as developmental. Deleted cases matching some generic names
2838 in favor of more specific names. (E.g., when we get Alpha
2839 support, we'll still only support VMS for Vax.)
2841 * config/tc-sparc.h (md_end): New macro.
2842 * config/tc-sparc.c (md_end): Function deleted.
2843 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2853 against placing additional object-file dependent code here. Warn
2854 against contaminating all of GAS with the internals of tc-hppa.c
2855 through inclusion of tc-hppa.h. Delete all forward declarations
2856 for functions only used within tc-hppa.c, likewise for structures,
2857 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2858 conditional code in a few small places.
2860 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2861 structures, global variables, forward declarations together.
2862 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2863 conditional code -- try to group conditional code together
2864 into a few places. Make all functions and variables which
2865 are only used within tc-hppa.c static. PARAMize all functions.
2866 Add comments to functions. Delete unused functions, variables,
2867 #defines, etc. Delete unused members within structures. Delete
2868 ldil;ble hacks -- it is believed they were installed to work
2869 around old gas bugs. Avoid using mixed case for local
2870 functions, variables, and structures. Fix formatting problems
2871 not found by GNU-indent. Add FIXME notices for things which
2872 should be worked on the near future. Delete lots of old
2873 useless (1.36 PA-SOM) code.

2885 which do not involve function symbols.
2887 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
2888 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
2890 * config/tc-hppa.c: Likewise.

2893 of elf32_symbol_type.
2894 (pa_export_args): Likewise.
2895 (elf_hppa_final_processing): Likewise.

2901 * config/tc-hppa.c: (md_section_align): Align all sections to
2902 a multiple of the section alignment rather than always a
2905 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2948 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2949 ELF, since the ELF object format does not have these type of
2950 relocations. Change the abort into as as_bad and return
2951 BFD_RELOC_NONE to silence compiler warnings.
2952 (md_assemble): Keep track of the instruction size. Allow white
2953 space between the $ and the constant for compatibility with older

5294 a29k .bss section; the mondfe program doesn't like it.

5315 source directory, if that's not the current directory.
5317 * configure.in (per-host): Accept MIPS host with BSD version

5343 avoid some redefinition complaints on some systems.
5344 (const, volatile): Don't need these conditionally defined if we
5345 use CONST and VOLATILE from ansidecl.h.
5346 (seg_name): Use CONST, not const.
5348 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5350 * config/tc-mips.c: Reindented to GNU standards.

5354 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5355 (fixup_segment): Add a29k special case; the linker is not prepared
5356 to see a segment offset here.
5358 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5361 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5363 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5364 srcdir, might be in objdir.
5366 * doc/Makefile.in: dvi depends on as.dvi

5379 bignums, but don't emit error message.
5381 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5383 * Makefile.in (targ-cpu.o): Depend on config.h.
5385 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5387 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5388 dropping a space immediately following an identifier.
5389 * expr.c, write.c: Rewrote assert expressions to not use multiple
5390 lines; I don't think that can be done portably.
5391 * config/tc-mips.c (macro): Use $AT if target register is zero in
5392 load instruction, which it can be for a floating point load.
5394 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
5396 * write.c (write_contents): Compute the relocs before writing out

5408 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5411 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5415 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5417 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5418 to be on a single line.
5420 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5422 * Makefile.in (config.h): Create file, writing out definitions of

5465 * config/tc-mips.c: Rearranged for ECOFF support. Added
5466 prototypes for all static functions. Moved existing minimal
5467 debugging format support info #ifndef OBJ_ECOFF blocks.

5516 * make-gas.com: Find obstack.obj if it's not in the current
5518 * read.c (s_ignore): Don't declare is_end_of_line. It's
5519 redundant, and triggers a VMS gcc compiler bug.
5521 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5522 current segment as an argument. (Ignored in all cases but VMS.)
5523 All callers and definitions changed.

5541 argument to s_ignore. Put "#if 0" around unused code.
5542 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5543 Call elf_xstabs for .stabs and .xstabs operators.

5820 md_relax_table): Use default zero initialization.
5821 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5822 latter, instead of selecting with preprocessor conditionals.
5824 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5826 * configure.in: recognise all sparclite variants

5836 * expr.c (operand): If character other than comma or newline is a
5837 logical end-of-line character, use the newline case.
5838 From Eric Youngdale:
5839 (operand): Set X_add_number field for floating-point numbers.
5840 (operand): Treat zero byte as end-of-operand.
5842 * configure.in (per-target): Look for with_bfd_assembler option.
5843 For now, only accept "no", until the merge is done.
5845 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5846 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5852 * expr.c: Add "const" modifier to hex_value.
5853 * symbols.c: Finish conversion to S_* macros in the VMS only
5854 parts of the program. Add "const" modifier to
5855 md_[long,short]_jump_size. Remove declaration of const_flag
5856 (which will be declared in obj-vms.h).
5857 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5858 Fix arguments to VMS_write_object_file.
5859 * config-gas.com: New file. Script for VMS systems to set up the
5860 configuration to build gas for VMS, and create config.status.
5861 * make-gas.com: Redone to work with new scheme.
5862 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5864 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

5867 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5868 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5869 types of malformed stabs. Change parsing algorithm so that we are
5870 more certain of having all of the information that we need on hand.
5871 * obj-vms.c (final_forward_reference): New function, used to help
5872 resolve the data types of as many struct elements as possible
5873 when some part of the struct is not fully defined by the compiler.

5876 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5877 as symbols as well in the object file. Look for external functions

5879 g++ compiler is incapable of doing this.
5880 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5882 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5883 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5884 have the name of the source file yet.
5885 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5887 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5889 * read.c (s_data): Always use "data_section", since it'll map to
5890 SEG_DATA or SEG_E1 if needed.
5891 (s_lcomm): Likewise with bss_section.
5892 (s_fill): Use memset, not bzero.
5894 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5916 (big_section, reg_section, pass1_section, diff_section,
5917 absent_section, text_section, data_section, bss_section): If
5918 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5919 mapping to segT enum values.
5920 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5921 if these are used or defined, if BFD_ASSEMBLER.
5922 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5923 subseg_new split into two functions.
5924 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5926 * as.h (volatile): Don't define if already defined.
5927 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5929 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5930 declare with format attribute for -Wformat checking.
5932 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5934 * app.c, config/tc-*.c: Don't include read.h, since it is already
5937 * These are based on patches from Minh Tran-le
5938 <mtranle@paris.intellicorp.com>.
5939 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5940 obj_format coffbfd and gas_target i386coff for target.
5941 (i[34]86-*-isc*): New host (uses sysv).
5942 * config/i386aix.mt: Removed (no longer used).
5943 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5945 (LDFLAGS): Added, defined as -shlib.
5946 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5947 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5948 (DOT_LABEL_PREFIX): Define.
5949 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5950 name rather than L0\001.

5962 (size_section): Restored sanity check.
5963 (do_relocs_for): Base section address on s_paddr rather than
5964 computing it. Adjust a29k R_IHIHALF special case to account for
5965 section paddr (used to require paddr to be zero). If there are no
5966 reclos, set s_relptr to 0. Set relocation size in object_headers.
5967 (fill_section): Always set s_vaddr here, removing
5968 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5969 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5970 Set STYP_INFO for .comment.
5971 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5972 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5974 H_{SET,GET}_* macros.
5975 (do_linenos_for): Set lineno size in object_headers.
5976 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5977 set s_vaddr here. If string_byte_count remains 4, set it back to
5978 0, and only write strings out if there are some. Call
5979 fill_section before do_relocs_for and do_linenos_for.
5980 (obj_coff_section): Handle optional quoted second argument giving
5981 section characteristics.
5982 (obj_coff_bss): Added to handle .bss.
5983 (obj_coff_ident): Added to handle .ident (puts string in .comment

6003 (do_scrub_next_char): For \", return " not '.
6004 (symbol_chars): Now const.
6006 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6007 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6009 * config/obj-coff.h: Don't use #elif.
6011 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6012 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6014 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6016 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6036 SEG_BSS, fill with NOP_OPCODE.
6037 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6038 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6039 using ZERO_BASED_SEGMENTS.
6040 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6041 never set segment address for SEG_E2 (.bss) and don't write out
6042 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6043 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6044 definitions, and don't merge tags with non-tags. Check for .bf
6045 rather than just checking whether the second character is b and
6046 the third character is f.
6047 (obj_coff_val): gcc can generate values which we don't handle
6048 correctly; discard information for now, since it only affects the
6049 debugging information.
6050 (tag_find_or_name): Don't insert tags in the symbol table.
6051 (yank_symbols): Don't merge labels.
6052 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6071 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
6072 power-of-two alignment for .align.
6074 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6075 and leave everything else alone.

6198 could be doing emulation.
6200 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6203 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6232 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6234 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6235 constant will not fit in an immediate field.
6236 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6273 * Support for i386-sysv.
6274 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6314 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6316 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6317 #elif, since it is not supported by old compilers.
6318 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6319 couple of expressions in tc-m68k.c.
6321 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6323 * read.c (cons): If NO_RELOC is defined, use it.
6325 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6327 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6329 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6330 local labels to start with a .) and set REGISTER_PREFIX to %.
6331 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6333 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6347 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6349 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6350 sections starting from zero, rather than making them consecutive.
6351 This makes subsequent reloc calculations easier, esp if the object
6352 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6353 allocate lcomm in .data rather than in .bss. It seems that some
6354 tools can't cope with a non-zero sized bss before linkage.
6356 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6358 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6377 * Makefile.in (install): if $(tooldir) exists, install as in
6380 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6382 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6383 .word is < -32768 or > 32767. The -J flag causes the error to be
6384 ignored. This is to catch over-sized switches generated by gcc on
6385 systems which don't support the broken .word hack.
6386 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6387 write.c (fixup_segment): check for signed .word overflow if
6388 WARN_SIGNED_OVERFLOW_WORD.
6390 * write.c (fixup_segment): fixed missing parens in expression
6391 checking for byte or word overflow.

6407 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6409 * input-scrub.c (input_scrub_push): call input_file_begin, not
6411 messages.c (as_perror): print ": " between the passed in error and
6412 the strerror, like perror does.

6417 From Steve Chamberlain:
6418 Makefile.in: Handle m68*-*-coff*.
6419 read.c, read.h: add mult argument to s_space
6421 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6422 Motorola and MIT syntax; gas can now assemble either type of
6424 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6431 (fixup_segment) set fx_subsy to 0.
6432 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6434 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6437 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6439 * Makefile.in (LIBS): Include opcode library.
6441 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6461 tc-i960.c (md_ri_to_chars): Always output bout object file in
6462 little endian byte order (used to use endianness of host).
6464 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6466 * config/tc-m68k.c (init_table): Now const. Always include 68851
6467 data, so that "bc" is available to 68040 cache instructions.
6468 Added "tt0", "tt1", and 68ec030 variants.
6469 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6470 (enum _register): Added TT0, TT1.
6471 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6472 line number correctly in "internal error" messages. Don't print
6473 architecture-mismatch message for operand errors.
6475 From Colin Smith (colin@wrs.com):
6476 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6477 than install_operand.

6493 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6494 so that we can assemble hand-written libgcc code.

6498 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6499 has already been formatted (but may still contain %-characters).
6502 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6504 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6505 written with indirection on the last two operands, which can be
6506 either data or address registers. Added a new operand type 'r'
6507 which accepts either register type. Added '(' to notend stuff in
6508 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6510 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6523 defined, call it. Change segments before calling fixup_segment.
6524 (relax_align): If linkrelax, provide extra padding.
6526 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6527 their not having symbols associated.
6529 * tc-i960.c (norelax, instrument_branches): Default initializer is
6531 (linkrelax): Delete variable definition.

6555 being used with args swapped, causing occasional lossage when
6556 refilling buffers after an include file.

6560 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6561 version. Discard bogus DONTDEF version.

6564 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6566 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6567 selected architecture, print a message saying so and listing what
6568 processors support it, rather than saying "operands mismatch".

6618 processor/opcode mismatch, so reword the error message.
6619 (md_assemble): If no CPU has been set (even if FPU/PMMU
6620 characteristics have been), default to 68020. Don't need extra
6621 quotes around error string.

6703 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6705 * write.c (write_object_file): keep the fix_tail clean, which
6706 fixes a bug in -R where relocations were being lost.
6708 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6710 * configure.in: recognize m680x0 as having sun3 emulation mode for

6755 start addresses to match required alignment.
6757 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6759 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6760 where gcc looks for it.
6762 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6764 * Makefile.in: Changed some lines to be less confusing for some

6830 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6832 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6834 * expr.c (operand): if can't work out what sort of operand it is,
6835 then look through FLT_CHARS for a hint.
6837 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6839 * Makefile.in, configure.in: removed traces of namesubdir,
6840 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6841 copyrights to '92, changed some from Cygnus to FSF.
6843 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6844 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6845 copyrights to '92, changed some from Cygnus to FSF.
6847 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6849 * expr.c: If an expression is single comma, then return with
6850 SEG_ABSENT rather than an error - since the sparc front end does
6851 really strange things with things like fbge,a
6853 * as.h: include bfd.h if using many sections
6854 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6855 local labels didn't work.
6856 * listing.c (list_symbol_table): don't core dump when there's no
6858 * write.c, write.h: call fix_new with the right number of args on
6860 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6863 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6865 * app.c: MRI compatibility - allow single quote to start a string.
6866 * as.c: fix typo recently introduced.
6867 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6868 * expr.c: Much rewriting, to accomodate MRI syntax for
6869 expressions. Also easier to read now.
6870 * listing.c: Put back defuns
6871 * read.c: modified to accept MRI syntax, put back listing pseudo
6872 ops so that an assembler built with NO_LISTING ignores list ops
6874 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6875 machine is a SPARC or a 29K.
6876 * config/obj-aout.c: added s_sect pseudo op
6877 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6878 fill in the timestamp.
6879 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6880 anymore, define all the relocs which the tc-<x> bit will use so we
6881 can translate from them to the coff types.
6882 * config/tc-a29k.c: reloc_type isn't ane enum any more
6883 * config/tc-m68k.c: Added NO_RELOC definition.
6885 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6887 * Makefile.in: put header files before C source for TAGS; remove
6888 references to non-existent syscalls.h.
6890 * read.c, write.c subsegs.c: back out the .bss changes.
6892 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6894 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6898 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6900 * symbols.c (local_label_name): symbols now start with ^A.
6902 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6903 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6904 generate these sections. .align: will use NOP_OPCODE or 0
6905 for padding. This is just for being nice to the
6908 * expr.c (operand): changed to generate local label "\001L0"
6909 starting with a ^A so that it is recognized as a local label.
6911 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6913 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6914 i/o opcodes - inb, inw, outb and outw. string manipulation with
6915 att syntax - scmp, slod, smov, ssca, ssto.
6917 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6918 to just after .file .
6920 In obj_crawl_symbol_chain() where it tries to put the external
6921 symbols apart, with the condition:
6922 (!S_IS_DEFINED(symbolP) &&
6923 !S_IS_DEBUG(symbolP) &&
6924 !SF_GET_STATICS(symbolP))
6925 it was moving too many symbols out. So I switch it back to the
6927 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6929 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6930 so that we don't use the F_RELFLG which make the linker complain
6931 that somebody has stripped the relocation info.
6933 Also, the AIX ld program require that the relocation table
6934 is sorted by r_vaddr like the standard ATT assembler does.
6936 [he also changed the sizeof(struct ...)'s into the coff
6937 style FOOSZ macros. I'm not sure this is right, but I can't
6938 remember why. xoxorich.]
6940 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6942 * Makefile.in, configure.in, doc: use the doc. Build it, install

6947 * read.c: white space and comments only.
6949 * configure.in: use the new atof-ns32.c for ns32k.
6951 * write.c: comment change only.
6953 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6954 aren't yet integrated.
6956 * tc-i860.[hc]: blew off the dust. Something must still be done
6957 about conflicting relocation types.
6959 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6962 * tc-i960.c, tc-sparc.c: white space and comments only.
6964 * tc-a29k.h: delete duplicate macro definition.
6966 * new file atof-ns32k.c copied from hack's last unreleased gas.
6968 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6970 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6973 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6974 ChangeLog's prior to this are sketchy at best. I have logs.
6975 They just aren't ChangeLogs.
6979 version-control: never
