109 VMS debugger now recognizes `long long' variables correctly.
110 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries

115 "complex float", "complex double", and "complex long double" are
118 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead

484 directory, and specify PSECT attributes explicitly to linker.
485 Also added missing label.
486 * Makefile.in (stamp-mk.com): Reference new variable
487 VMS_OTHER_OBJS for list of non-local object files, instead of

504 argument, the reloc type.
505 (load_register): Pass reloc type to macro_build for 'u'.
506 (macro): Likewise. For M_LA_AB permit a difference expression
507 when generating embedded PIC code between an arbitrary symbol and
508 a symbol in the .text section.
509 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
510 BFD_RELOC_PCREL_LO16 to be emitted.
511 (md_apply_fix): Check that most relocs are not PC relative.
512 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
513 (tc_gen_reloc): Change #error to as_fatal. Handle
514 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.

553 elf_tc_make_sections stuff. It was there to support PA braindamage
554 which has been fixed, and in the case of elf_tc_make_sections is
555 redundant with elf_tc_final_processing.

575 don't spew remainder of input file in error message.
576 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
577 message with reloc type and try to process remainder of file.
579 * doc/Makefile.in (install-info-as, install-info-gasp): New
580 targets, now explicitly checking $(srcdir) for info files.

589 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
590 flag rather than signedp field. Only permit extended range if
591 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
592 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
594 * config/tc-ppc.c (ppc_size): New static variable.
595 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

617 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
618 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

630 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
632 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
633 branch with an instruction that uses $at, in case the branch is
635 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
636 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
637 to make it pcrel_offset.
638 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
639 reloc->address; another gruesome hack to get gas reloc handling to
642 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
644 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

648 (md_assemble): Call it.
649 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
651 (lituse_pending): New variable. Set by anything that generates a
652 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
653 tested by code that might want to emit a LITUSE reloc.
654 (emit_unaligned_io): New function. Currently calls md_assemble,
655 but it should eventually be converted to generate the insn itself
656 and call emit_insn directly.
657 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
658 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
659 emit_bis_r): Likewise.

666 the value can't be resolved.
668 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
670 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
671 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

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

706 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
708 * Makefile.in (config-stamp): If `defs' is defined, emit a
709 preprocessor directive to create a macro named by this value into
710 config.new; don't explicitly go for BFD_ASSEMBLER.
711 * configure.in: Define `defs', not `BFDDEF'. Set it to
712 MANY_SEGMENTS for any obj-coffbfd target.
713 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
714 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
716 (LOCAL_LOADLIBES): Deleted.
717 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
718 * config/m88kcoff.mt (TDEFINES): Ditto.

744 bfd_set_symtab is called.
745 (dump_section_relocs): Note whether a symbol is a section symbol
747 (adjust_reloc_syms): For now, always supply an absolute symbol for
748 fixups without symbols but not yet `done'. Use section_symbol to
749 get the symbol, instead of going directly for abs_symbol.
750 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
751 reloc is not a section symbol and is not in the symbol table.
752 (set_symtab): New function, broken out from write_object_file.
753 Counts symbol table instead of relying on an earlier count.
754 (write_object_file): Call set_symtab, but do it after potentially
755 invoking the *_frob_file macros. Don't bother counting symbols.
756 Call symbol_remove, instead of expanding it in place. Moved the
757 conditionalized `object_file_size' declaration down to
758 conditionalized block where it's used. When using the absolute
759 symbol for a fixup without a symbol, set sy_used_in_reloc.
760 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
761 the correct symbol for the absolute section.
763 * subsegs.c (section_symbol): Use symbol_new instead of
764 symbol_make, since we may want it to go into the symbol table.
765 Make the new symbol have internal linkage. If
766 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
767 symbol with the newly created GAS symbol.
768 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
769 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

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

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

829 * write.c (write_object_file): Check both S_IS_LOCAL and
830 S_IS_EXTERNAL when deciding whether to discard a symbol.
832 * config-gas.com: Scan Makefile.in, not version.c, for current
833 version number. Delete all versions of temp files when finished
834 with them. Create config.h.
836 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
837 values to reduce number of lookups with S_GET_VALUE. Skip debug

839 holger@botbso.rhein-main.de.)
840 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
841 field. (Also from Holger Teutsch.) Watch for a would-be register
842 mask that spans frags.
844 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
845 this_base, not line_base. (Patch from Andreas Arens,
846 ari@obelix.av.rwth-aachen.de.)
848 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
849 look local if they're exported or undefined. Used to be done for
852 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

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

2861 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2862 the table, require that the one without bit 0x1000000 set come
2863 first. Require further that it be case 'b' or 'P'. The a29k

2917 * write.c (write_relocs): For relocs that are pc_relative and
2918 pcrel_offset and not partial_inplace, adjust reloc->addend to

2974 for keeping or rejecting configurations still under development;
2975 default is to assume production environment, and reject configs
2976 still being worked on. Mark Elf configurations (except sparc and
2977 i386) as developmental. Deleted cases matching some generic names
2978 in favor of more specific names. (E.g., when we get Alpha

2995 through inclusion of tc-hppa.h. Delete all forward declarations
2996 for functions only used within tc-hppa.c, likewise for structures,
2997 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2998 conditional code in a few small places.
3000 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3001 structures, global variables, forward declarations together.

3003 conditional code -- try to group conditional code together
3004 into a few places. Make all functions and variables which
3005 are only used within tc-hppa.c static. PARAMize all functions.
3006 Add comments to functions. Delete unused functions, variables,
3007 #defines, etc. Delete unused members within structures. Delete
3008 ldil;ble hacks -- it is believed they were installed to work
3009 around old gas bugs. Avoid using mixed case for local
3010 functions, variables, and structures. Fix formatting problems
3011 not found by GNU-indent. Add FIXME notices for things which
3012 should be worked on the near future. Delete lots of old
3013 useless (1.36 PA-SOM) code.

3030 * config/tc-hppa.c: Likewise.
3032 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3033 of elf32_symbol_type.
3034 (pa_export_args): Likewise.
3035 (elf_hppa_final_processing): Likewise.

3041 * config/tc-hppa.c: (md_section_align): Align all sections to
3042 a multiple of the section alignment rather than always a
3045 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3046 bits are zero (eg they specify no relocations), then do not even
3047 bother adding their entries to thesymextn section.

3086 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3088 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3089 ELF, since the ELF object format does not have these type of
3090 relocations. Change the abort into as as_bad and return
3091 BFD_RELOC_NONE to silence compiler warnings.
3092 (md_assemble): Keep track of the instruction size. Allow white
3093 space between the $ and the constant for compatibility with older
3094 gases and other assemblers.
3095 (i386_operand): Skip spaces between $ and expression.
3096 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5483 avoid some redefinition complaints on some systems.

5531 * config/tc-mips.c (macro): Use $AT if target register is zero in
5532 load instruction, which it can be for a floating point load.

5658 * read.c (s_ignore): Don't declare is_end_of_line. It's
5659 redundant, and triggers a VMS gcc compiler bug.

5980 (operand): Treat zero byte as end-of-operand.
5982 * configure.in (per-target): Look for with_bfd_assembler option.
5983 For now, only accept "no", until the merge is done.
5985 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5986 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5997 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5998 Fix arguments to VMS_write_object_file.
5999 * config-gas.com: New file. Script for VMS systems to set up the

6061 if these are used or defined, if BFD_ASSEMBLER.
6062 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6063 subseg_new split into two functions.
6064 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6066 * as.h (volatile): Don't define if already defined.

6093 * symbols.c, symbols.h (local_bss_counter): Removed.
6094 * write.c (write_object_file): bss no longer uses
6095 local_bss_counter. Pass correct data and bss size to
6096 VMS_write_object_file.
6097 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
6098 argument, rather than using local_bss_counter.

6100 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
6101 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
6102 (size_section): Restored sanity check.
6103 (do_relocs_for): Base section address on s_paddr rather than
6104 computing it. Adjust a29k R_IHIHALF special case to account for
6105 section paddr (used to require paddr to be zero). If there are no
6106 reclos, set s_relptr to 0. Set relocation size in object_headers.
6107 (fill_section): Always set s_vaddr here, removing
6108 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6109 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6110 Set STYP_INFO for .comment.
6111 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6112 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
6113 (crawl_symbols): Handle 8 character section name correctly. Use
6114 H_{SET,GET}_* macros.
6115 (do_linenos_for): Set lineno size in object_headers.
6116 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6117 set s_vaddr here. If string_byte_count remains 4, set it back to
6118 0, and only write strings out if there are some. Call
6119 fill_section before do_relocs_for and do_linenos_for.
6120 (obj_coff_section): Handle optional quoted second argument giving
6121 section characteristics.
6122 (obj_coff_bss): Added to handle .bss.
6123 (obj_coff_ident): Added to handle .ident (puts string in .comment
6125 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6126 (fixup_mdeps): Change to segment. Call frag_wane after
6128 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6129 adjustment (already happened only for common symbols, but this is
6131 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
6132 * config/tc-i386.c (s_bss): Don't use if I386COFF.

6140 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
6142 * app.c (app_push): Use memcpy, not bcopy.
6143 (do_scrub_next_char): For \", return " not '.
6144 (symbol_chars): Now const.
6146 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6147 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6149 * config/obj-coff.h: Don't use #elif.
6151 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6152 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6154 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6179 using ZERO_BASED_SEGMENTS.
6180 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6181 never set segment address for SEG_E2 (.bss) and don't write out
6182 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6183 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6184 definitions, and don't merge tags with non-tags. Check for .bf
6185 rather than just checking whether the second character is b and
6186 the third character is f.
6187 (obj_coff_val): gcc can generate values which we don't handle
6188 correctly; discard information for now, since it only affects the
6189 debugging information.
6190 (tag_find_or_name): Don't insert tags in the symbol table.
6191 (yank_symbols): Don't merge labels.
6192 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6195 (obj_coff_section): Accept and ignore a trailing quoted string, as
6196 used in AT&T i386 syntax.
6197 (fixup_segment): Take segment as argument. On the i386, adjust PC
6198 relative addends by the segment vaddr.
6199 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6200 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6337 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6338 could be doing emulation.
6340 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6343 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6372 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6374 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6375 constant will not fit in an immediate field.
6376 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6411 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6413 * Support for i386-sysv.
6414 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6438 * tc-m68k.c (get_num): make it work for all segments, not just the
6441 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6443 * configure.in: recognize i386-*-bsd emulation.

6452 * tc-z8k.c: lots of bug fixes
6454 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6456 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6457 #elif, since it is not supported by old compilers.
6458 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6459 couple of expressions in tc-m68k.c.
6461 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6463 * read.c (cons): If NO_RELOC is defined, use it.

6467 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6469 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6470 local labels to start with a .) and set REGISTER_PREFIX to %.
6471 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6473 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6484 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6487 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6489 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6490 sections starting from zero, rather than making them consecutive.
6491 This makes subsequent reloc calculations easier, esp if the object
6492 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6493 allocate lcomm in .data rather than in .bss. It seems that some
6494 tools can't cope with a non-zero sized bss before linkage.
6496 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6498 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6499 throughout. That enum no longer means what we thought it meant.
6501 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6502 "-mno-688[58]1" options.
6504 * tc-m68k.c: Added CPU32 support.

6515 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6517 * Makefile.in (install): if $(tooldir) exists, install as in
6520 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6522 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6523 .word is < -32768 or > 32767. The -J flag causes the error to be
6524 ignored. This is to catch over-sized switches generated by gcc on
6525 systems which don't support the broken .word hack.
6526 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6527 write.c (fixup_segment): check for signed .word overflow if
6528 WARN_SIGNED_OVERFLOW_WORD.
6530 * write.c (fixup_segment): fixed missing parens in expression
6531 checking for byte or word overflow.
6533 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6545 * tc-i386.h : new coff defines
6547 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6549 * input-scrub.c (input_scrub_push): call input_file_begin, not
6551 messages.c (as_perror): print ": " between the passed in error and
6552 the strerror, like perror does.
6554 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6556 * Makefile.in: use gas_target instead of modifying target_cpu.
6557 From Steve Chamberlain:
6558 Makefile.in: Handle m68*-*-coff*.
6559 read.c, read.h: add mult argument to s_space
6561 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6562 Motorola and MIT syntax; gas can now assemble either type of
6564 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6565 From Steve Chamberlain:
6566 m68kcoff.mt: for m68k COFF.
6567 obj-coffbfd.c: (fixup_mdeps) added
6568 (size_section) removed bad sanity check
6569 (fill_section) added rs_machine_dependent case
6570 (write_object_file) call fixup_mdeps
6571 (fixup_segment) set fx_subsy to 0.
6572 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6574 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6577 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6579 * Makefile.in (LIBS): Include opcode library.

6642 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6644 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6645 written with indirection on the last two operands, which can be
6646 either data or address registers. Added a new operand type 'r'
6647 which accepts either register type. Added '(' to notend stuff in
6648 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6760 characteristics have been), default to 68020. Don't need extra
6761 quotes around error string.

6897 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6899 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6900 where gcc looks for it.

6979 * Makefile.in, configure.in: removed traces of namesubdir,

6983 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6984 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6985 copyrights to '92, changed some from Cygnus to FSF.
6987 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6989 * expr.c: If an expression is single comma, then return with
6990 SEG_ABSENT rather than an error - since the sparc front end does
6991 really strange things with things like fbge,a
6993 * as.h: include bfd.h if using many sections
6994 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6995 local labels didn't work.
6996 * listing.c (list_symbol_table): don't core dump when there's no
6998 * write.c, write.h: call fix_new with the right number of args on
7000 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7003 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7005 * app.c: MRI compatibility - allow single quote to start a string.
7006 * as.c: fix typo recently introduced.
7007 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7008 * expr.c: Much rewriting, to accomodate MRI syntax for
7009 expressions. Also easier to read now.
7010 * listing.c: Put back defuns
7011 * read.c: modified to accept MRI syntax, put back listing pseudo
7012 ops so that an assembler built with NO_LISTING ignores list ops
7014 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7015 machine is a SPARC or a 29K.
7016 * config/obj-aout.c: added s_sect pseudo op
7017 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7018 fill in the timestamp.
7019 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7020 anymore, define all the relocs which the tc-<x> bit will use so we
7021 can translate from them to the coff types.
7022 * config/tc-a29k.c: reloc_type isn't ane enum any more
7023 * config/tc-m68k.c: Added NO_RELOC definition.
7025 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7027 * Makefile.in: put header files before C source for TAGS; remove
7028 references to non-existent syscalls.h.
7030 * read.c, write.c subsegs.c: back out the .bss changes.
7032 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7034 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7038 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7040 * symbols.c (local_label_name): symbols now start with ^A.
7042 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7043 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7044 generate these sections. .align: will use NOP_OPCODE or 0
7045 for padding. This is just for being nice to the
7048 * expr.c (operand): changed to generate local label "\001L0"
7049 starting with a ^A so that it is recognized as a local label.
7051 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7053 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7054 i/o opcodes - inb, inw, outb and outw. string manipulation with
7055 att syntax - scmp, slod, smov, ssca, ssto.
7057 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7058 to just after .file .
7060 In obj_crawl_symbol_chain() where it tries to put the external
7061 symbols apart, with the condition:
7062 (!S_IS_DEFINED(symbolP) &&
7063 !S_IS_DEBUG(symbolP) &&
7064 !SF_GET_STATICS(symbolP))
7065 it was moving too many symbols out. So I switch it back to the
7067 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7069 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7070 so that we don't use the F_RELFLG which make the linker complain
7071 that somebody has stripped the relocation info.
7073 Also, the AIX ld program require that the relocation table
7074 is sorted by r_vaddr like the standard ATT assembler does.
7076 [he also changed the sizeof(struct ...)'s into the coff
7077 style FOOSZ macros. I'm not sure this is right, but I can't
7078 remember why. xoxorich.]

7102 * tc-i960.c, tc-sparc.c: white space and comments only.
