189 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
191 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
192 can be used within a label name.

226 all arguments have been processed.

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

512 (load_address): Handle EMBEDDED_PIC.
513 (macro): Handle EMBEDDED_PIC in all PIC cases.
514 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
515 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
516 -non_shared to use NO_PIC (this is how the Irix 5 assembler
517 works). Do not permit -G with SVR4_PIC.
518 (s_abicalls): Warn if -G was used, and force -G 0.
519 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
520 anything but a.out, not just for ELF. For ECOFF, don't generate a
521 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
523 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
525 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

531 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
533 * Makefile.in (config-stamp): If `defs' is defined, emit a
534 preprocessor directive to create a macro named by this value into
535 config.new; don't explicitly go for BFD_ASSEMBLER.
536 * configure.in: Define `defs', not `BFDDEF'. Set it to
537 MANY_SEGMENTS for any obj-coffbfd target.
538 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
539 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
541 (LOCAL_LOADLIBES): Deleted.
542 * config/m68kcoff.mt (TDEFINES): Don't define those macros.

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

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

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

658 version number. Delete all versions of temp files when finished
659 with them. Create config.h.
661 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
662 values to reduce number of lookups with S_GET_VALUE. Skip debug

664 holger@botbso.rhein-main.de.)
665 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
666 field. (Also from Holger Teutsch.) Watch for a would-be register
667 mask that spans frags.
669 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
670 this_base, not line_base. (Patch from Andreas Arens,
671 ari@obelix.av.rwth-aachen.de.)
673 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
674 look local if they're exported or undefined. Used to be done for
677 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

2391 messages and only print them when "print_errors" is true. Handle
2392 empty string case like the HP assembler -- assume a value of
2395 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2396 standard hpux include files to pick up various function decls.

2464 pass new argument for i, j and o cases.
2465 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2468 rather than hard coded constants.
2469 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2686 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2687 the table, require that the one without bit 0x1000000 set come
2688 first. Require further that it be case 'b' or 'P'. The a29k

2794 OPTIONAL_REGISTER_PREFIX if either is already defined.
2796 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
2798 * configure.in: Set bfd_gas for all sparc targets. Added facility
2799 for keeping or rejecting configurations still under development;
2800 default is to assume production environment, and reject configs
2801 still being worked on. Mark Elf configurations (except sparc and
2802 i386) as developmental. Deleted cases matching some generic names
2803 in favor of more specific names. (E.g., when we get Alpha
2804 support, we'll still only support VMS for Vax.)
2806 * config/tc-sparc.h (md_end): New macro.
2807 * config/tc-sparc.c (md_end): Function deleted.
2808 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2818 against placing additional object-file dependent code here. Warn
2819 against contaminating all of GAS with the internals of tc-hppa.c
2820 through inclusion of tc-hppa.h. Delete all forward declarations
2821 for functions only used within tc-hppa.c, likewise for structures,
2822 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2823 conditional code in a few small places.
2825 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2826 structures, global variables, forward declarations together.
2827 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2828 conditional code -- try to group conditional code together
2829 into a few places. Make all functions and variables which
2830 are only used within tc-hppa.c static. PARAMize all functions.
2831 Add comments to functions. Delete unused functions, variables,
2832 #defines, etc. Delete unused members within structures. Delete
2833 ldil;ble hacks -- it is believed they were installed to work
2834 around old gas bugs. Avoid using mixed case for local
2835 functions, variables, and structures. Fix formatting problems
2836 not found by GNU-indent. Add FIXME notices for things which
2837 should be worked on the near future. Delete lots of old

3981 * Extensive changes to permit symbols to contain any expression
3982 type and to delay the computation of the expression until the
3983 value is actually needed. This permits setting symbols to values
3984 calculated based on object code size. Expressions were changed to
3985 no longer be in a section, to stop the overloading of segment and
3986 expression type that previously occurred.
3988 * as.c (big_section, pass1_section, diff_section, absent_section):
3990 (expr_section): Added (used for dummy symbols which hold

4099 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
4100 calculating opP->isiz; this permits the expression size to be
4101 determined as well, later on.

5308 avoid some redefinition complaints on some systems.
5309 (const, volatile): Don't need these conditionally defined if we
5310 use CONST and VOLATILE from ansidecl.h.
5311 (seg_name): Use CONST, not const.
5313 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5315 * config/tc-mips.c: Reindented to GNU standards.

5319 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

5326 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5328 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5348 * Makefile.in (targ-cpu.o): Depend on config.h.
5350 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5352 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5353 dropping a space immediately following an identifier.
5354 * expr.c, write.c: Rewrote assert expressions to not use multiple
5355 lines; I don't think that can be done portably.
5356 * config/tc-mips.c (macro): Use $AT if target register is zero in
5357 load instruction, which it can be for a floating point load.
5359 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5380 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5382 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5383 to be on a single line.

5431 prototypes for all static functions. Moved existing minimal
5432 debugging format support info #ifndef OBJ_ECOFF blocks.

5435 all callers accordingly.
5436 (tc_get_register): Renamed from get_register, and made non-static.
5438 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5481 * make-gas.com: Find obstack.obj if it's not in the current
5483 * read.c (s_ignore): Don't declare is_end_of_line. It's
5484 redundant, and triggers a VMS gcc compiler bug.
5486 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5487 current segment as an argument. (Ignored in all cases but VMS.)
5488 All callers and definitions changed.

5785 md_relax_table): Use default zero initialization.
5786 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5787 latter, instead of selecting with preprocessor conditionals.
5789 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5791 * configure.in: recognise all sparclite variants

5801 * expr.c (operand): If character other than comma or newline is a
5802 logical end-of-line character, use the newline case.
5803 From Eric Youngdale:
5804 (operand): Set X_add_number field for floating-point numbers.
5805 (operand): Treat zero byte as end-of-operand.
5807 * configure.in (per-target): Look for with_bfd_assembler option.
5808 For now, only accept "no", until the merge is done.
5810 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5811 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5812 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5813 * read.c: Finish conversion to S_* macros in the VMS only
5814 parts of the program. Add "const" modifier to hex_value.
5815 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5817 * expr.c: Add "const" modifier to hex_value.
5818 * symbols.c: Finish conversion to S_* macros in the VMS only
5819 parts of the program. Add "const" modifier to
5820 md_[long,short]_jump_size. Remove declaration of const_flag
5821 (which will be declared in obj-vms.h).
5822 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5823 Fix arguments to VMS_write_object_file.
5824 * config-gas.com: New file. Script for VMS systems to set up the
5825 configuration to build gas for VMS, and create config.status.
5826 * make-gas.com: Redone to work with new scheme.
5827 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5829 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5830 will swap bytes if needed on a big endian system. Use throughout
5832 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5833 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5834 types of malformed stabs. Change parsing algorithm so that we are
5835 more certain of having all of the information that we need on hand.
5836 * obj-vms.c (final_forward_reference): New function, used to help
5837 resolve the data types of as many struct elements as possible
5838 when some part of the struct is not fully defined by the compiler.

5841 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5842 as symbols as well in the object file. Look for external functions
5843 that start with "__vt.", and turn them into variables, since the
5844 g++ compiler is incapable of doing this.
5845 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5847 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5848 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5849 have the name of the source file yet.
5850 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5852 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5854 * read.c (s_data): Always use "data_section", since it'll map to
5855 SEG_DATA or SEG_E1 if needed.
5856 (s_lcomm): Likewise with bss_section.
5857 (s_fill): Use memset, not bzero.
5859 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5881 (big_section, reg_section, pass1_section, diff_section,
5882 absent_section, text_section, data_section, bss_section): If
5883 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5884 mapping to segT enum values.
5885 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5886 if these are used or defined, if BFD_ASSEMBLER.
5887 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5888 subseg_new split into two functions.
5889 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5891 * as.h (volatile): Don't define if already defined.
5892 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5894 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5895 declare with format attribute for -Wformat checking.
5897 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5899 * app.c, config/tc-*.c: Don't include read.h, since it is already
5902 * These are based on patches from Minh Tran-le
5903 <mtranle@paris.intellicorp.com>.
5904 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5905 obj_format coffbfd and gas_target i386coff for target.
5906 (i[34]86-*-isc*): New host (uses sysv).
5907 * config/i386aix.mt: Removed (no longer used).
5908 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5910 (LDFLAGS): Added, defined as -shlib.
5911 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5912 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5913 (DOT_LABEL_PREFIX): Define.
5914 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5915 name rather than L0\001.
5916 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5918 * symbols.c, symbols.h (local_bss_counter): Removed.
5919 * write.c (write_object_file): bss no longer uses
5920 local_bss_counter. Pass correct data and bss size to
5921 VMS_write_object_file.

5927 (size_section): Restored sanity check.
5928 (do_relocs_for): Base section address on s_paddr rather than
5929 computing it. Adjust a29k R_IHIHALF special case to account for
5930 section paddr (used to require paddr to be zero). If there are no
5931 reclos, set s_relptr to 0. Set relocation size in object_headers.
5932 (fill_section): Always set s_vaddr here, removing
5933 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5934 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5935 Set STYP_INFO for .comment.
5936 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5937 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5939 H_{SET,GET}_* macros.
5940 (do_linenos_for): Set lineno size in object_headers.
5941 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5942 set s_vaddr here. If string_byte_count remains 4, set it back to
5943 0, and only write strings out if there are some. Call
5944 fill_section before do_relocs_for and do_linenos_for.
5945 (obj_coff_section): Handle optional quoted second argument giving
5946 section characteristics.
5947 (obj_coff_bss): Added to handle .bss.
5948 (obj_coff_ident): Added to handle .ident (puts string in .comment

5968 (do_scrub_next_char): For \", return " not '.
5969 (symbol_chars): Now const.
5971 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5972 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5974 * config/obj-coff.h: Don't use #elif.
5976 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5977 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5979 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5981 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6001 SEG_BSS, fill with NOP_OPCODE.
6002 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6003 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6004 using ZERO_BASED_SEGMENTS.
6005 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6006 never set segment address for SEG_E2 (.bss) and don't write out
6007 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6008 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6009 definitions, and don't merge tags with non-tags. Check for .bf
6010 rather than just checking whether the second character is b and
6011 the third character is f.
6012 (obj_coff_val): gcc can generate values which we don't handle
6013 correctly; discard information for now, since it only affects the
6014 debugging information.
6015 (tag_find_or_name): Don't insert tags in the symbol table.
6016 (yank_symbols): Don't merge labels.
6017 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6072 options. Updated options documentation for m68k. Some minor
6073 wording/punctuation changes.
6075 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6077 * configure.in: Accept target OS "vms".

6163 could be doing emulation.
6165 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6168 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6238 * Support for i386-sysv.
6239 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6279 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6281 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6282 #elif, since it is not supported by old compilers.
6283 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6284 couple of expressions in tc-m68k.c.
6286 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6288 * read.c (cons): If NO_RELOC is defined, use it.
6290 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6292 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6294 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6295 local labels to start with a .) and set REGISTER_PREFIX to %.

6312 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6314 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6315 sections starting from zero, rather than making them consecutive.
6316 This makes subsequent reloc calculations easier, esp if the object
6317 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6318 allocate lcomm in .data rather than in .bss. It seems that some
6319 tools can't cope with a non-zero sized bss before linkage.
6321 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6323 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6340 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6342 * Makefile.in (install): if $(tooldir) exists, install as in
6345 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6347 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6348 .word is < -32768 or > 32767. The -J flag causes the error to be
6349 ignored. This is to catch over-sized switches generated by gcc on
6350 systems which don't support the broken .word hack.
6351 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6352 write.c (fixup_segment): check for signed .word overflow if
6353 WARN_SIGNED_OVERFLOW_WORD.
6355 * write.c (fixup_segment): fixed missing parens in expression
6356 checking for byte or word overflow.

6370 * tc-i386.h : new coff defines
6372 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6374 * input-scrub.c (input_scrub_push): call input_file_begin, not
6376 messages.c (as_perror): print ": " between the passed in error and
6377 the strerror, like perror does.
6379 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6381 * Makefile.in: use gas_target instead of modifying target_cpu.
6382 From Steve Chamberlain:
6383 Makefile.in: Handle m68*-*-coff*.
6384 read.c, read.h: add mult argument to s_space
6386 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6387 Motorola and MIT syntax; gas can now assemble either type of
6389 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6396 (fixup_segment) set fx_subsy to 0.
6397 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6399 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6402 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6404 * Makefile.in (LIBS): Include opcode library.
6406 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6426 tc-i960.c (md_ri_to_chars): Always output bout object file in
6427 little endian byte order (used to use endianness of host).
6429 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6431 * config/tc-m68k.c (init_table): Now const. Always include 68851
6432 data, so that "bc" is available to 68040 cache instructions.
6433 Added "tt0", "tt1", and 68ec030 variants.
6434 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6435 (enum _register): Added TT0, TT1.
6436 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6437 line number correctly in "internal error" messages. Don't print
6438 architecture-mismatch message for operand errors.
6440 From Colin Smith (colin@wrs.com):
6441 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6442 than install_operand.

6446 * listing.c (buffer_line): rewind to the start of include
6447 files, they might be included twice.

6456 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6458 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6459 so that we can assemble hand-written libgcc code.
6461 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6463 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6464 has already been formatted (but may still contain %-characters).
6467 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6469 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6470 written with indirection on the last two operands, which can be
6471 either data or address registers. Added a new operand type 'r'
6472 which accepts either register type. Added '(' to notend stuff in
6473 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6475 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6477 * as.h (enum _relax_state): Start off at one, not zero, to better

6491 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6492 their not having symbols associated.
6494 * tc-i960.c (norelax, instrument_branches): Default initializer is
6496 (linkrelax): Delete variable definition.

6519 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6520 being used with args swapped, causing occasional lossage when
6521 refilling buffers after an include file.
6523 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6525 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6526 version. Discard bogus DONTDEF version.
6527 (as_warn, as_bad, as_fatal): Likewise.
6529 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6531 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6532 selected architecture, print a message saying so and listing what

6573 fx_offset into account.
6575 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
6577 * configure.in (mips host): Accept "ultrix" with version number.
6579 * expr.c (floating_constant): Separate "=-" to avoid confusing
6580 ancient or broken compilers.
6582 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6583 processor/opcode mismatch, so reword the error message.
6584 (md_assemble): If no CPU has been set (even if FPU/PMMU

6722 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6724 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6725 where gcc looks for it.
6727 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6729 * Makefile.in: Changed some lines to be less confusing for some

6795 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6797 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6799 * expr.c (operand): if can't work out what sort of operand it is,
6800 then look through FLT_CHARS for a hint.
6802 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6804 * Makefile.in, configure.in: removed traces of namesubdir,

6806 copyrights to '92, changed some from Cygnus to FSF.
6808 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6809 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6810 copyrights to '92, changed some from Cygnus to FSF.
6812 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6814 * expr.c: If an expression is single comma, then return with
6815 SEG_ABSENT rather than an error - since the sparc front end does
6816 really strange things with things like fbge,a
6818 * as.h: include bfd.h if using many sections
6819 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6820 local labels didn't work.
6821 * listing.c (list_symbol_table): don't core dump when there's no
6823 * write.c, write.h: call fix_new with the right number of args on
6825 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6828 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6830 * app.c: MRI compatibility - allow single quote to start a string.
6831 * as.c: fix typo recently introduced.
6832 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6833 * expr.c: Much rewriting, to accomodate MRI syntax for
6834 expressions. Also easier to read now.
6835 * listing.c: Put back defuns
6836 * read.c: modified to accept MRI syntax, put back listing pseudo
6837 ops so that an assembler built with NO_LISTING ignores list ops
6839 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6840 machine is a SPARC or a 29K.
6841 * config/obj-aout.c: added s_sect pseudo op
6842 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6843 fill in the timestamp.
6844 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6845 anymore, define all the relocs which the tc-<x> bit will use so we
6846 can translate from them to the coff types.
6847 * config/tc-a29k.c: reloc_type isn't ane enum any more
6848 * config/tc-m68k.c: Added NO_RELOC definition.
6850 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6852 * Makefile.in: put header files before C source for TAGS; remove
6853 references to non-existent syscalls.h.
6855 * read.c, write.c subsegs.c: back out the .bss changes.
6857 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6859 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6863 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6865 * symbols.c (local_label_name): symbols now start with ^A.
6867 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6868 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6869 generate these sections. .align: will use NOP_OPCODE or 0
6870 for padding. This is just for being nice to the
6873 * expr.c (operand): changed to generate local label "\001L0"
6874 starting with a ^A so that it is recognized as a local label.
6876 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6878 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6879 i/o opcodes - inb, inw, outb and outw. string manipulation with
6880 att syntax - scmp, slod, smov, ssca, ssto.
6882 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6883 to just after .file .
6885 In obj_crawl_symbol_chain() where it tries to put the external
6886 symbols apart, with the condition:
6887 (!S_IS_DEFINED(symbolP) &&
6888 !S_IS_DEBUG(symbolP) &&
6889 !SF_GET_STATICS(symbolP))
6890 it was moving too many symbols out. So I switch it back to the
6892 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6894 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6895 so that we don't use the F_RELFLG which make the linker complain
6896 that somebody has stripped the relocation info.
6898 Also, the AIX ld program require that the relocation table
6899 is sorted by r_vaddr like the standard ATT assembler does.
6901 [he also changed the sizeof(struct ...)'s into the coff
6902 style FOOSZ macros. I'm not sure this is right, but I can't
6903 remember why. xoxorich.]
6905 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6907 * Makefile.in, configure.in, doc: use the doc. Build it, install

6912 * read.c: white space and comments only.
6914 * configure.in: use the new atof-ns32.c for ns32k.
6916 * write.c: comment change only.
6918 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6919 aren't yet integrated.
6921 * tc-i860.[hc]: blew off the dust. Something must still be done
6922 about conflicting relocation types.
6924 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6927 * tc-i960.c, tc-sparc.c: white space and comments only.
6929 * tc-a29k.h: delete duplicate macro definition.
6931 * new file atof-ns32k.c copied from hack's last unreleased gas.
6933 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6935 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6938 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6939 ChangeLog's prior to this are sketchy at best. I have logs.
6940 They just aren't ChangeLogs.
6944 version-control: never
