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

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

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

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

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

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

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

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

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

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

2834 in favor of more specific names. (E.g., when we get Alpha
2835 support, we'll still only support VMS for Vax.)
2837 * config/tc-sparc.h (md_end): New macro.
2838 * config/tc-sparc.c (md_end): Function deleted.
2839 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2849 against placing additional object-file dependent code here. Warn
2850 against contaminating all of GAS with the internals of tc-hppa.c
2851 through inclusion of tc-hppa.h. Delete all forward declarations
2852 for functions only used within tc-hppa.c, likewise for structures,
2853 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2854 conditional code in a few small places.
2856 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2857 structures, global variables, forward declarations together.
2858 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2859 conditional code -- try to group conditional code together
2860 into a few places. Make all functions and variables which
2861 are only used within tc-hppa.c static. PARAMize all functions.
2862 Add comments to functions. Delete unused functions, variables,
2863 #defines, etc. Delete unused members within structures. Delete
2864 ldil;ble hacks -- it is believed they were installed to work
2865 around old gas bugs. Avoid using mixed case for local
2866 functions, variables, and structures. Fix formatting problems
2867 not found by GNU-indent. Add FIXME notices for things which
2868 should be worked on the near future. Delete lots of old
2869 useless (1.36 PA-SOM) code.

2889 of elf32_symbol_type.
2890 (pa_export_args): Likewise.
2891 (elf_hppa_final_processing): Likewise.

2897 * config/tc-hppa.c: (md_section_align): Align all sections to
2898 a multiple of the section alignment rather than always a
2901 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2944 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2945 ELF, since the ELF object format does not have these type of
2946 relocations. Change the abort into as as_bad and return
2947 BFD_RELOC_NONE to silence compiler warnings.
2948 (md_assemble): Keep track of the instruction size. Allow white
2949 space between the $ and the constant for compatibility with older

4012 * Extensive changes to permit symbols to contain any expression
4013 type and to delay the computation of the expression until the
4014 value is actually needed. This permits setting symbols to values
4015 calculated based on object code size. Expressions were changed to
4016 no longer be in a section, to stop the overloading of segment and
4017 expression type that previously occurred.
4019 * as.c (big_section, pass1_section, diff_section, absent_section):

5311 source directory, if that's not the current directory.
5313 * configure.in (per-host): Accept MIPS host with BSD version

5339 avoid some redefinition complaints on some systems.
5340 (const, volatile): Don't need these conditionally defined if we
5341 use CONST and VOLATILE from ansidecl.h.
5342 (seg_name): Use CONST, not const.
5344 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5346 * config/tc-mips.c: Reindented to GNU standards.

5350 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5351 (fixup_segment): Add a29k special case; the linker is not prepared
5352 to see a segment offset here.
5354 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5357 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5359 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5360 srcdir, might be in objdir.

5375 bignums, but don't emit error message.
5377 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5379 * Makefile.in (targ-cpu.o): Depend on config.h.
5381 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5383 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5384 dropping a space immediately following an identifier.
5385 * expr.c, write.c: Rewrote assert expressions to not use multiple
5386 lines; I don't think that can be done portably.
5387 * config/tc-mips.c (macro): Use $AT if target register is zero in
5388 load instruction, which it can be for a floating point load.
5390 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5411 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5413 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5414 to be on a single line.

5462 prototypes for all static functions. Moved existing minimal
5463 debugging format support info #ifndef OBJ_ECOFF blocks.

5512 * make-gas.com: Find obstack.obj if it's not in the current
5514 * read.c (s_ignore): Don't declare is_end_of_line. It's
5515 redundant, and triggers a VMS gcc compiler bug.
5517 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5518 current segment as an argument. (Ignored in all cases but VMS.)
5519 All callers and definitions changed.

5538 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5539 Call elf_xstabs for .stabs and .xstabs operators.

5816 md_relax_table): Use default zero initialization.
5817 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5818 latter, instead of selecting with preprocessor conditionals.
5820 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5822 * configure.in: recognise all sparclite variants

5832 * expr.c (operand): If character other than comma or newline is a
5833 logical end-of-line character, use the newline case.
5834 From Eric Youngdale:
5835 (operand): Set X_add_number field for floating-point numbers.
5836 (operand): Treat zero byte as end-of-operand.
5838 * configure.in (per-target): Look for with_bfd_assembler option.
5839 For now, only accept "no", until the merge is done.
5841 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5842 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5848 * expr.c: Add "const" modifier to hex_value.
5849 * symbols.c: Finish conversion to S_* macros in the VMS only
5850 parts of the program. Add "const" modifier to
5851 md_[long,short]_jump_size. Remove declaration of const_flag
5852 (which will be declared in obj-vms.h).
5853 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5854 Fix arguments to VMS_write_object_file.
5855 * config-gas.com: New file. Script for VMS systems to set up the
5856 configuration to build gas for VMS, and create config.status.
5857 * make-gas.com: Redone to work with new scheme.
5858 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5860 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5861 will swap bytes if needed on a big endian system. Use throughout
5863 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5864 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5865 types of malformed stabs. Change parsing algorithm so that we are
5866 more certain of having all of the information that we need on hand.
5867 * obj-vms.c (final_forward_reference): New function, used to help
5868 resolve the data types of as many struct elements as possible
5869 when some part of the struct is not fully defined by the compiler.

5872 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5873 as symbols as well in the object file. Look for external functions
5874 that start with "__vt.", and turn them into variables, since the
5875 g++ compiler is incapable of doing this.
5876 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5878 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5879 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5880 have the name of the source file yet.
5881 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5883 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5885 * read.c (s_data): Always use "data_section", since it'll map to
5886 SEG_DATA or SEG_E1 if needed.
5887 (s_lcomm): Likewise with bss_section.
5888 (s_fill): Use memset, not bzero.
5890 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5912 (big_section, reg_section, pass1_section, diff_section,
5913 absent_section, text_section, data_section, bss_section): If
5914 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5915 mapping to segT enum values.
5916 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5917 if these are used or defined, if BFD_ASSEMBLER.
5918 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5919 subseg_new split into two functions.
5920 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5922 * as.h (volatile): Don't define if already defined.
5923 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5925 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5926 declare with format attribute for -Wformat checking.
5928 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5930 * app.c, config/tc-*.c: Don't include read.h, since it is already
5933 * These are based on patches from Minh Tran-le
5934 <mtranle@paris.intellicorp.com>.
5935 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5936 obj_format coffbfd and gas_target i386coff for target.
5937 (i[34]86-*-isc*): New host (uses sysv).
5938 * config/i386aix.mt: Removed (no longer used).
5939 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5941 (LDFLAGS): Added, defined as -shlib.
5942 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5943 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5944 (DOT_LABEL_PREFIX): Define.
5945 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5946 name rather than L0\001.
5947 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5949 * symbols.c, symbols.h (local_bss_counter): Removed.

5958 (size_section): Restored sanity check.
5959 (do_relocs_for): Base section address on s_paddr rather than
5960 computing it. Adjust a29k R_IHIHALF special case to account for
5961 section paddr (used to require paddr to be zero). If there are no
5962 reclos, set s_relptr to 0. Set relocation size in object_headers.
5963 (fill_section): Always set s_vaddr here, removing
5964 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5965 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5966 Set STYP_INFO for .comment.
5967 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5968 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5970 H_{SET,GET}_* macros.
5971 (do_linenos_for): Set lineno size in object_headers.
5972 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5973 set s_vaddr here. If string_byte_count remains 4, set it back to
5974 0, and only write strings out if there are some. Call
5975 fill_section before do_relocs_for and do_linenos_for.
5976 (obj_coff_section): Handle optional quoted second argument giving
5977 section characteristics.
5978 (obj_coff_bss): Added to handle .bss.
5979 (obj_coff_ident): Added to handle .ident (puts string in .comment

5999 (do_scrub_next_char): For \", return " not '.
6000 (symbol_chars): Now const.
6002 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6003 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6005 * config/obj-coff.h: Don't use #elif.
6007 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6008 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6010 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6012 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6032 SEG_BSS, fill with NOP_OPCODE.
6033 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6034 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6035 using ZERO_BASED_SEGMENTS.
6036 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6037 never set segment address for SEG_E2 (.bss) and don't write out
6038 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6039 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6040 definitions, and don't merge tags with non-tags. Check for .bf
6041 rather than just checking whether the second character is b and
6042 the third character is f.
6043 (obj_coff_val): gcc can generate values which we don't handle
6044 correctly; discard information for now, since it only affects the
6045 debugging information.
6046 (tag_find_or_name): Don't insert tags in the symbol table.
6047 (yank_symbols): Don't merge labels.
6048 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6067 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
6068 power-of-two alignment for .align.
6070 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6071 and leave everything else alone.
6073 Fri Dec 4 16:58:42 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

6194 could be doing emulation.
6196 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6199 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6228 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6230 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6231 constant will not fit in an immediate field.
6232 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6269 * Support for i386-sysv.
6270 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6308 * tc-z8k.c: lots of bug fixes
6310 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6312 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6313 #elif, since it is not supported by old compilers.
6314 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6315 couple of expressions in tc-m68k.c.
6317 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6319 * read.c (cons): If NO_RELOC is defined, use it.
6321 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6323 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6325 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6326 local labels to start with a .) and set REGISTER_PREFIX to %.
6327 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6329 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6343 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6345 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6346 sections starting from zero, rather than making them consecutive.
6347 This makes subsequent reloc calculations easier, esp if the object
6348 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6349 allocate lcomm in .data rather than in .bss. It seems that some
6350 tools can't cope with a non-zero sized bss before linkage.
6352 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6354 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6373 * Makefile.in (install): if $(tooldir) exists, install as in
6376 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6378 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6379 .word is < -32768 or > 32767. The -J flag causes the error to be
6380 ignored. This is to catch over-sized switches generated by gcc on
6381 systems which don't support the broken .word hack.
6382 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6383 write.c (fixup_segment): check for signed .word overflow if
6384 WARN_SIGNED_OVERFLOW_WORD.
6386 * write.c (fixup_segment): fixed missing parens in expression
6387 checking for byte or word overflow.

6403 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6405 * input-scrub.c (input_scrub_push): call input_file_begin, not
6407 messages.c (as_perror): print ": " between the passed in error and
6408 the strerror, like perror does.

6413 From Steve Chamberlain:
6414 Makefile.in: Handle m68*-*-coff*.
6415 read.c, read.h: add mult argument to s_space
6417 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6418 Motorola and MIT syntax; gas can now assemble either type of

6427 (fixup_segment) set fx_subsy to 0.
6428 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6430 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6433 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6435 * Makefile.in (LIBS): Include opcode library.
6437 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6460 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6462 * config/tc-m68k.c (init_table): Now const. Always include 68851
6463 data, so that "bc" is available to 68040 cache instructions.
6464 Added "tt0", "tt1", and 68ec030 variants.
6465 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6466 (enum _register): Added TT0, TT1.
6467 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6468 line number correctly in "internal error" messages. Don't print
6469 architecture-mismatch message for operand errors.
6471 From Colin Smith (colin@wrs.com):
6472 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6473 than install_operand.

6477 * listing.c (buffer_line): rewind to the start of include
6478 files, they might be included twice.

6489 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6490 so that we can assemble hand-written libgcc code.

6494 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6495 has already been formatted (but may still contain %-characters).
6498 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6500 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6501 written with indirection on the last two operands, which can be
6502 either data or address registers. Added a new operand type 'r'
6503 which accepts either register type. Added '(' to notend stuff in
6504 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6506 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6520 (relax_align): If linkrelax, provide extra padding.
6522 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6523 their not having symbols associated.
6525 * tc-i960.c (norelax, instrument_branches): Default initializer is
6527 (linkrelax): Delete variable definition.

6551 being used with args swapped, causing occasional lossage when
6552 refilling buffers after an include file.

6556 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6557 version. Discard bogus DONTDEF version.

6560 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6562 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6563 selected architecture, print a message saying so and listing what
6564 processors support it, rather than saying "operands mismatch".

6614 processor/opcode mismatch, so reword the error message.
6615 (md_assemble): If no CPU has been set (even if FPU/PMMU
6616 characteristics have been), default to 68020. Don't need extra
6617 quotes around error string.

6699 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6701 * write.c (write_object_file): keep the fix_tail clean, which
6702 fixes a bug in -R where relocations were being lost.
6704 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6706 * configure.in: recognize m680x0 as having sun3 emulation mode for

6751 start addresses to match required alignment.
6753 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6755 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6756 where gcc looks for it.
6758 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6760 * Makefile.in: Changed some lines to be less confusing for some

6826 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6828 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6830 * expr.c (operand): if can't work out what sort of operand it is,
6831 then look through FLT_CHARS for a hint.
6833 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6835 * Makefile.in, configure.in: removed traces of namesubdir,
6836 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6837 copyrights to '92, changed some from Cygnus to FSF.
6839 * doc/Makefile.in, doc/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 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6845 * expr.c: If an expression is single comma, then return with
6846 SEG_ABSENT rather than an error - since the sparc front end does
6847 really strange things with things like fbge,a
6849 * as.h: include bfd.h if using many sections
6850 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6851 local labels didn't work.
6852 * listing.c (list_symbol_table): don't core dump when there's no
6854 * write.c, write.h: call fix_new with the right number of args on
6856 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6859 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6861 * app.c: MRI compatibility - allow single quote to start a string.
6862 * as.c: fix typo recently introduced.
6863 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6864 * expr.c: Much rewriting, to accomodate MRI syntax for
6865 expressions. Also easier to read now.
6866 * listing.c: Put back defuns
6867 * read.c: modified to accept MRI syntax, put back listing pseudo
6868 ops so that an assembler built with NO_LISTING ignores list ops
6870 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6871 machine is a SPARC or a 29K.
6872 * config/obj-aout.c: added s_sect pseudo op
6873 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6874 fill in the timestamp.
6875 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6876 anymore, define all the relocs which the tc-<x> bit will use so we
6877 can translate from them to the coff types.
6878 * config/tc-a29k.c: reloc_type isn't ane enum any more
6879 * config/tc-m68k.c: Added NO_RELOC definition.
6881 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6883 * Makefile.in: put header files before C source for TAGS; remove
6884 references to non-existent syscalls.h.
6886 * read.c, write.c subsegs.c: back out the .bss changes.
6888 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6890 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6894 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6896 * symbols.c (local_label_name): symbols now start with ^A.
6898 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6899 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6900 generate these sections. .align: will use NOP_OPCODE or 0
6901 for padding. This is just for being nice to the
6904 * expr.c (operand): changed to generate local label "\001L0"
6905 starting with a ^A so that it is recognized as a local label.
6907 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6909 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6910 i/o opcodes - inb, inw, outb and outw. string manipulation with
6911 att syntax - scmp, slod, smov, ssca, ssto.
6913 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6914 to just after .file .
6916 In obj_crawl_symbol_chain() where it tries to put the external
6917 symbols apart, with the condition:
6918 (!S_IS_DEFINED(symbolP) &&
6919 !S_IS_DEBUG(symbolP) &&
6920 !SF_GET_STATICS(symbolP))
6921 it was moving too many symbols out. So I switch it back to the
6923 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6925 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6926 so that we don't use the F_RELFLG which make the linker complain
6927 that somebody has stripped the relocation info.
6929 Also, the AIX ld program require that the relocation table
6930 is sorted by r_vaddr like the standard ATT assembler does.
6932 [he also changed the sizeof(struct ...)'s into the coff
6933 style FOOSZ macros. I'm not sure this is right, but I can't
6934 remember why. xoxorich.]
6936 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6938 * Makefile.in, configure.in, doc: use the doc. Build it, install

6943 * read.c: white space and comments only.
6945 * configure.in: use the new atof-ns32.c for ns32k.
6947 * write.c: comment change only.
6949 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6950 aren't yet integrated.
6952 * tc-i860.[hc]: blew off the dust. Something must still be done
6953 about conflicting relocation types.
6955 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6958 * tc-i960.c, tc-sparc.c: white space and comments only.
6960 * tc-a29k.h: delete duplicate macro definition.
6962 * new file atof-ns32k.c copied from hack's last unreleased gas.
6964 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6966 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6969 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6970 ChangeLog's prior to this are sketchy at best. I have logs.
6971 They just aren't ChangeLogs.
6975 version-control: never
