242 all arguments have been processed.

492 (lituse_pending): New variable. Set by anything that generates a
493 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
494 tested by code that might want to emit a LITUSE reloc.
495 (emit_unaligned_io): New function. Currently calls md_assemble,
496 but it should eventually be converted to generate the insn itself
497 and call emit_insn directly.
498 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
499 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
500 emit_bis_r): Likewise.

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

515 (mips_force_relocation): New function.
516 (md_apply_fix): Set fixP->fx_done appropriately.

525 * config/tc-mips.c (enum mips_pic_level): New enum.
526 (mips_pic): Change from int to enum mips_pic_level. Change all
527 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
528 (load_address): Handle EMBEDDED_PIC.
529 (macro): Handle EMBEDDED_PIC in all PIC cases.
530 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
531 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
532 -non_shared to use NO_PIC (this is how the Irix 5 assembler
533 works). Do not permit -G with SVR4_PIC.
534 (s_abicalls): Warn if -G was used, and force -G 0.
535 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
536 anything but a.out, not just for ELF. For ECOFF, don't generate a
537 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
539 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
541 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

544 parameters to avoid losing when compiling with HP CC.
545 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
547 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
549 * Makefile.in (config-stamp): If `defs' is defined, emit a
550 preprocessor directive to create a macro named by this value into
551 config.new; don't explicitly go for BFD_ASSEMBLER.
552 * configure.in: Define `defs', not `BFDDEF'. Set it to
553 MANY_SEGMENTS for any obj-coffbfd target.
554 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
555 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
557 (LOCAL_LOADLIBES): Deleted.
558 * config/m68kcoff.mt (TDEFINES): Don't define those macros.

585 bfd_set_symtab is called.
586 (dump_section_relocs): Note whether a symbol is a section symbol
588 (adjust_reloc_syms): For now, always supply an absolute symbol for
589 fixups without symbols but not yet `done'. Use section_symbol to
590 get the symbol, instead of going directly for abs_symbol.
591 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
592 reloc is not a section symbol and is not in the symbol table.
593 (set_symtab): New function, broken out from write_object_file.
594 Counts symbol table instead of relying on an earlier count.
595 (write_object_file): Call set_symtab, but do it after potentially
596 invoking the *_frob_file macros. Don't bother counting symbols.
597 Call symbol_remove, instead of expanding it in place. Moved the
598 conditionalized `object_file_size' declaration down to
599 conditionalized block where it's used. When using the absolute
600 symbol for a fixup without a symbol, set sy_used_in_reloc.
601 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
602 the correct symbol for the absolute section.
604 * subsegs.c (section_symbol): Use symbol_new instead of
605 symbol_make, since we may want it to go into the symbol table.
606 Make the new symbol have internal linkage. If
607 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
608 symbol with the newly created GAS symbol.
609 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
610 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

615 (in_signed_range): New function.
617 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
618 (sparc_ip, label "immediate"): Reject constants for pcrel
619 instructions only if the relocation type indicates a "call"
620 instruction and the offset is within range of a "jmpl %g0". If
621 it's not in range, use the absolute section symbol plus an offset.
622 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
624 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
626 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
629 * configure.in: Eliminated all targets using obj-coff but not
630 defining BFD_ASSEMBLER; I think all such targets that are
631 supported will be matched by real CPU-OS combinations earlier in
633 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
634 some comments about the dpx2 configuration, but left it disabled,
635 since it couldn't be reached before.
636 (target a29k-amd-ebmonold): Deleted.
638 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

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

671 S_IS_EXTERNAL when deciding whether to discard a symbol.
673 * config-gas.com: Scan Makefile.in, not version.c, for current
674 version number. Delete all versions of temp files when finished
675 with them. Create config.h.
677 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
678 values to reduce number of lookups with S_GET_VALUE. Skip debug

680 holger@botbso.rhein-main.de.)
681 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
682 field. (Also from Holger Teutsch.) Watch for a would-be register
683 mask that spans frags.
685 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
686 this_base, not line_base. (Patch from Andreas Arens,
687 ari@obelix.av.rwth-aachen.de.)
689 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
690 look local if they're exported or undefined. Used to be done for
693 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

2818 i386) as developmental. Deleted cases matching some generic names
2819 in favor of more specific names. (E.g., when we get Alpha

2847 Add comments to functions. Delete unused functions, variables,
2848 #defines, etc. Delete unused members within structures. Delete
2849 ldil;ble hacks -- it is believed they were installed to work
2850 around old gas bugs. Avoid using mixed case for local
2851 functions, variables, and structures. Fix formatting problems

3997 * Extensive changes to permit symbols to contain any expression
3998 type and to delay the computation of the expression until the
3999 value is actually needed. This permits setting symbols to values
4000 calculated based on object code size. Expressions were changed to
4001 no longer be in a section, to stop the overloading of segment and
4002 expression type that previously occurred.
4004 * as.c (big_section, pass1_section, diff_section, absent_section):
4006 (expr_section): Added (used for dummy symbols which hold

4115 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
4116 calculating opP->isiz; this permits the expression size to be
4117 determined as well, later on.
4119 * expr.c (clean_up_expression): Don't cancel the subtraction of
4122 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

4131 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
4133 * read.c (float_cons): Simplified parsing logic. If
4134 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
4136 * symbols.c (colon): Rather than a special case for TC_HPPA,
4137 use new macro tc_frob_label.
4138 * config/tc-hppa.h (tc_frob_label): Define.
4140 * config/tc-mips.c: Many changes to support simple assembler

5296 source directory, if that's not the current directory.
5298 * configure.in (per-host): Accept MIPS host with BSD version

5324 avoid some redefinition complaints on some systems.
5325 (const, volatile): Don't need these conditionally defined if we
5326 use CONST and VOLATILE from ansidecl.h.
5327 (seg_name): Use CONST, not const.
5329 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5331 * config/tc-mips.c: Reindented to GNU standards.

5335 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5336 (fixup_segment): Add a29k special case; the linker is not prepared
5337 to see a segment offset here.

5342 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5344 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5345 srcdir, might be in objdir.

5364 * Makefile.in (targ-cpu.o): Depend on config.h.
5366 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5368 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5369 dropping a space immediately following an identifier.
5370 * expr.c, write.c: Rewrote assert expressions to not use multiple
5371 lines; I don't think that can be done portably.
5372 * config/tc-mips.c (macro): Use $AT if target register is zero in
5373 load instruction, which it can be for a floating point load.
5375 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5396 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5398 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5399 to be on a single line.

5447 prototypes for all static functions. Moved existing minimal
5448 debugging format support info #ifndef OBJ_ECOFF blocks.

5497 * make-gas.com: Find obstack.obj if it's not in the current
5499 * read.c (s_ignore): Don't declare is_end_of_line. It's
5500 redundant, and triggers a VMS gcc compiler bug.
5502 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5503 current segment as an argument. (Ignored in all cases but VMS.)
5504 All callers and definitions changed.

5801 md_relax_table): Use default zero initialization.
5802 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5803 latter, instead of selecting with preprocessor conditionals.
5805 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5807 * configure.in: recognise all sparclite variants

5817 * expr.c (operand): If character other than comma or newline is a
5818 logical end-of-line character, use the newline case.
5819 From Eric Youngdale:
5820 (operand): Set X_add_number field for floating-point numbers.
5821 (operand): Treat zero byte as end-of-operand.
5823 * configure.in (per-target): Look for with_bfd_assembler option.
5824 For now, only accept "no", until the merge is done.
5826 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5827 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5829 * read.c: Finish conversion to S_* macros in the VMS only
5830 parts of the program. Add "const" modifier to hex_value.
5831 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5833 * expr.c: Add "const" modifier to hex_value.
5834 * symbols.c: Finish conversion to S_* macros in the VMS only
5835 parts of the program. Add "const" modifier to
5836 md_[long,short]_jump_size. Remove declaration of const_flag
5837 (which will be declared in obj-vms.h).
5838 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5839 Fix arguments to VMS_write_object_file.
5840 * config-gas.com: New file. Script for VMS systems to set up the
5841 configuration to build gas for VMS, and create config.status.
5842 * make-gas.com: Redone to work with new scheme.
5843 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5845 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5846 will swap bytes if needed on a big endian system. Use throughout
5848 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5849 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5850 types of malformed stabs. Change parsing algorithm so that we are
5851 more certain of having all of the information that we need on hand.
5852 * obj-vms.c (final_forward_reference): New function, used to help
5853 resolve the data types of as many struct elements as possible
5854 when some part of the struct is not fully defined by the compiler.

5857 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5858 as symbols as well in the object file. Look for external functions
5859 that start with "__vt.", and turn them into variables, since the
5860 g++ compiler is incapable of doing this.
5861 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5863 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5864 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5865 have the name of the source file yet.
5866 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5868 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5870 * read.c (s_data): Always use "data_section", since it'll map to
5871 SEG_DATA or SEG_E1 if needed.
5872 (s_lcomm): Likewise with bss_section.
5873 (s_fill): Use memset, not bzero.
5875 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5897 (big_section, reg_section, pass1_section, diff_section,
5898 absent_section, text_section, data_section, bss_section): If
5899 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5900 mapping to segT enum values.
5901 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5902 if these are used or defined, if BFD_ASSEMBLER.
5903 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5904 subseg_new split into two functions.
5905 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5907 * as.h (volatile): Don't define if already defined.
5908 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5910 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5911 declare with format attribute for -Wformat checking.
5913 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5915 * app.c, config/tc-*.c: Don't include read.h, since it is already
5918 * These are based on patches from Minh Tran-le
5919 <mtranle@paris.intellicorp.com>.
5920 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5921 obj_format coffbfd and gas_target i386coff for target.
5922 (i[34]86-*-isc*): New host (uses sysv).
5923 * config/i386aix.mt: Removed (no longer used).
5924 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5926 (LDFLAGS): Added, defined as -shlib.
5927 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5928 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5929 (DOT_LABEL_PREFIX): Define.
5930 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5931 name rather than L0\001.
5932 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5934 * symbols.c, symbols.h (local_bss_counter): Removed.
5935 * write.c (write_object_file): bss no longer uses

5943 (size_section): Restored sanity check.
5944 (do_relocs_for): Base section address on s_paddr rather than
5945 computing it. Adjust a29k R_IHIHALF special case to account for
5946 section paddr (used to require paddr to be zero). If there are no
5947 reclos, set s_relptr to 0. Set relocation size in object_headers.
5948 (fill_section): Always set s_vaddr here, removing
5949 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5950 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5951 Set STYP_INFO for .comment.
5952 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5953 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5955 H_{SET,GET}_* macros.
5956 (do_linenos_for): Set lineno size in object_headers.
5957 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5958 set s_vaddr here. If string_byte_count remains 4, set it back to
5959 0, and only write strings out if there are some. Call
5960 fill_section before do_relocs_for and do_linenos_for.
5961 (obj_coff_section): Handle optional quoted second argument giving
5962 section characteristics.
5963 (obj_coff_bss): Added to handle .bss.
5964 (obj_coff_ident): Added to handle .ident (puts string in .comment

5984 (do_scrub_next_char): For \", return " not '.
5985 (symbol_chars): Now const.
5987 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5988 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5990 * config/obj-coff.h: Don't use #elif.
5992 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5993 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5995 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5997 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6017 SEG_BSS, fill with NOP_OPCODE.
6018 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6019 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6020 using ZERO_BASED_SEGMENTS.
6021 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6022 never set segment address for SEG_E2 (.bss) and don't write out
6023 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6024 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6025 definitions, and don't merge tags with non-tags. Check for .bf
6026 rather than just checking whether the second character is b and
6027 the third character is f.
6028 (obj_coff_val): gcc can generate values which we don't handle
6029 correctly; discard information for now, since it only affects the
6030 debugging information.
6031 (tag_find_or_name): Don't insert tags in the symbol table.
6032 (yank_symbols): Don't merge labels.
6033 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6053 power-of-two alignment for .align.
6055 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6056 and leave everything else alone.

6179 could be doing emulation.
6181 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6184 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6213 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6215 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6216 constant will not fit in an immediate field.
6217 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6254 * Support for i386-sysv.
6255 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6297 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6298 #elif, since it is not supported by old compilers.
6299 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6300 couple of expressions in tc-m68k.c.
6302 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6304 * read.c (cons): If NO_RELOC is defined, use it.
6306 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6308 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6310 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6311 local labels to start with a .) and set REGISTER_PREFIX to %.
6312 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6314 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6328 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6330 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6331 sections starting from zero, rather than making them consecutive.
6332 This makes subsequent reloc calculations easier, esp if the object
6333 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6334 allocate lcomm in .data rather than in .bss. It seems that some
6335 tools can't cope with a non-zero sized bss before linkage.
6337 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6339 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6358 * Makefile.in (install): if $(tooldir) exists, install as in
6361 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6363 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6364 .word is < -32768 or > 32767. The -J flag causes the error to be
6365 ignored. This is to catch over-sized switches generated by gcc on
6366 systems which don't support the broken .word hack.
6367 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6368 write.c (fixup_segment): check for signed .word overflow if
6369 WARN_SIGNED_OVERFLOW_WORD.
6371 * write.c (fixup_segment): fixed missing parens in expression

6388 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6390 * input-scrub.c (input_scrub_push): call input_file_begin, not
6392 messages.c (as_perror): print ": " between the passed in error and
6393 the strerror, like perror does.

6398 From Steve Chamberlain:
6399 Makefile.in: Handle m68*-*-coff*.
6400 read.c, read.h: add mult argument to s_space
6402 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6403 Motorola and MIT syntax; gas can now assemble either type of
6405 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6412 (fixup_segment) set fx_subsy to 0.
6413 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6415 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6418 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6420 * Makefile.in (LIBS): Include opcode library.
6422 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6445 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6447 * config/tc-m68k.c (init_table): Now const. Always include 68851
6448 data, so that "bc" is available to 68040 cache instructions.
6449 Added "tt0", "tt1", and 68ec030 variants.
6450 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6451 (enum _register): Added TT0, TT1.
6452 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6453 line number correctly in "internal error" messages. Don't print
6454 architecture-mismatch message for operand errors.
6456 From Colin Smith (colin@wrs.com):
6457 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6458 than install_operand.

6474 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6475 so that we can assemble hand-written libgcc code.

6479 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6480 has already been formatted (but may still contain %-characters).
6483 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6485 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6486 written with indirection on the last two operands, which can be
6487 either data or address registers. Added a new operand type 'r'
6488 which accepts either register type. Added '(' to notend stuff in
6489 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6491 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6507 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6508 their not having symbols associated.
6510 * tc-i960.c (norelax, instrument_branches): Default initializer is
6512 (linkrelax): Delete variable definition.

6536 being used with args swapped, causing occasional lossage when
6537 refilling buffers after an include file.
6539 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6541 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6542 version. Discard bogus DONTDEF version.

6547 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6548 selected architecture, print a message saying so and listing what

6686 * write.c (write_object_file): keep the fix_tail clean, which
6687 fixes a bug in -R where relocations were being lost.
6689 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6691 * configure.in: recognize m680x0 as having sun3 emulation mode for

6738 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6740 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6741 where gcc looks for it.
6743 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6745 * Makefile.in: Changed some lines to be less confusing for some

6811 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6813 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6815 * expr.c (operand): if can't work out what sort of operand it is,
6816 then look through FLT_CHARS for a hint.
6818 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6820 * Makefile.in, configure.in: removed traces of namesubdir,
6821 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6822 copyrights to '92, changed some from Cygnus to FSF.
6824 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6825 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6826 copyrights to '92, changed some from Cygnus to FSF.
6828 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6830 * expr.c: If an expression is single comma, then return with
6831 SEG_ABSENT rather than an error - since the sparc front end does
6832 really strange things with things like fbge,a
6834 * as.h: include bfd.h if using many sections
6835 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6836 local labels didn't work.
6837 * listing.c (list_symbol_table): don't core dump when there's no
6839 * write.c, write.h: call fix_new with the right number of args on
6841 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6844 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6846 * app.c: MRI compatibility - allow single quote to start a string.
6847 * as.c: fix typo recently introduced.
6848 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6849 * expr.c: Much rewriting, to accomodate MRI syntax for
6850 expressions. Also easier to read now.
6851 * listing.c: Put back defuns
6852 * read.c: modified to accept MRI syntax, put back listing pseudo
6853 ops so that an assembler built with NO_LISTING ignores list ops
6855 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6856 machine is a SPARC or a 29K.
6857 * config/obj-aout.c: added s_sect pseudo op
6858 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6859 fill in the timestamp.
6860 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6861 anymore, define all the relocs which the tc-<x> bit will use so we
6862 can translate from them to the coff types.
6863 * config/tc-a29k.c: reloc_type isn't ane enum any more
6864 * config/tc-m68k.c: Added NO_RELOC definition.
6866 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6868 * Makefile.in: put header files before C source for TAGS; remove
6869 references to non-existent syscalls.h.
6871 * read.c, write.c subsegs.c: back out the .bss changes.
6873 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6875 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6879 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6881 * symbols.c (local_label_name): symbols now start with ^A.
6883 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6884 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6885 generate these sections. .align: will use NOP_OPCODE or 0
6886 for padding. This is just for being nice to the
6889 * expr.c (operand): changed to generate local label "\001L0"
6890 starting with a ^A so that it is recognized as a local label.
6892 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6894 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6895 i/o opcodes - inb, inw, outb and outw. string manipulation with
6896 att syntax - scmp, slod, smov, ssca, ssto.
6898 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6899 to just after .file .
6901 In obj_crawl_symbol_chain() where it tries to put the external
6902 symbols apart, with the condition:
6903 (!S_IS_DEFINED(symbolP) &&
6904 !S_IS_DEBUG(symbolP) &&
6905 !SF_GET_STATICS(symbolP))
6906 it was moving too many symbols out. So I switch it back to the
6908 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6910 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6911 so that we don't use the F_RELFLG which make the linker complain
6912 that somebody has stripped the relocation info.
6914 Also, the AIX ld program require that the relocation table
6915 is sorted by r_vaddr like the standard ATT assembler does.
6917 [he also changed the sizeof(struct ...)'s into the coff
6918 style FOOSZ macros. I'm not sure this is right, but I can't
6919 remember why. xoxorich.]
6921 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6923 * Makefile.in, configure.in, doc: use the doc. Build it, install

6928 * read.c: white space and comments only.
6930 * configure.in: use the new atof-ns32.c for ns32k.
6932 * write.c: comment change only.
6934 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6935 aren't yet integrated.
6937 * tc-i860.[hc]: blew off the dust. Something must still be done
6938 about conflicting relocation types.
6940 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6943 * tc-i960.c, tc-sparc.c: white space and comments only.
6945 * tc-a29k.h: delete duplicate macro definition.
6947 * new file atof-ns32k.c copied from hack's last unreleased gas.
6949 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6951 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6954 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6955 ChangeLog's prior to this are sketchy at best. I have logs.
6956 They just aren't ChangeLogs.
6960 version-control: never
