124 VMS debugger now recognizes `long long' variables correctly.
125 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
126 for gcc2's predefined types "long double" (same as double, as

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

519 argument, the reloc type.
520 (load_register): Pass reloc type to macro_build for 'u'.
521 (macro): Likewise. For M_LA_AB permit a difference expression
522 when generating embedded PIC code between an arbitrary symbol and
523 a symbol in the .text section.

525 BFD_RELOC_PCREL_LO16 to be emitted.
526 (md_apply_fix): Check that most relocs are not PC relative.
527 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.

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

590 don't spew remainder of input file in error message.
591 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
592 message with reloc type and try to process remainder of file.
594 * doc/Makefile.in (install-info-as, install-info-gasp): New
595 targets, now explicitly checking $(srcdir) for info files.
596 (install-info): Depend on both of them; do nothing more.

604 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
605 flag rather than signedp field. Only permit extended range if
606 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
607 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
609 * config/tc-ppc.c (ppc_size): New static variable.
610 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
611 (md_begin): If an instruction has a size specific flag set, only
612 add it if we are assembling that size.
614 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
616 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
617 cross section PC relative relocs right for COFF and ELF.

632 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
633 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
634 and -many (all architectures).

644 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
645 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
647 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
648 branch with an instruction that uses $at, in case the branch is
650 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
651 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
652 to make it pcrel_offset.
653 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
654 reloc->address; another gruesome hack to get gas reloc handling to
657 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
659 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

663 (md_assemble): Call it.
664 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
666 (lituse_pending): New variable. Set by anything that generates a
667 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
668 tested by code that might want to emit a LITUSE reloc.
669 (emit_unaligned_io): New function. Currently calls md_assemble,
670 but it should eventually be converted to generate the insn itself
671 and call emit_insn directly.
672 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
673 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
674 emit_bis_r): Likewise.

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

699 * config/tc-mips.c (enum mips_pic_level): New enum.
700 (mips_pic): Change from int to enum mips_pic_level. Change all
701 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
702 (load_address): Handle EMBEDDED_PIC.
703 (macro): Handle EMBEDDED_PIC in all PIC cases.
704 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
705 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
706 -non_shared to use NO_PIC (this is how the Irix 5 assembler
707 works). Do not permit -G with SVR4_PIC.
708 (s_abicalls): Warn if -G was used, and force -G 0.
709 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
710 anything but a.out, not just for ELF. For ECOFF, don't generate a
711 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
713 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
715 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

721 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
723 * Makefile.in (config-stamp): If `defs' is defined, emit a
724 preprocessor directive to create a macro named by this value into
725 config.new; don't explicitly go for BFD_ASSEMBLER.
726 * configure.in: Define `defs', not `BFDDEF'. Set it to
727 MANY_SEGMENTS for any obj-coffbfd target.
728 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
729 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
731 (LOCAL_LOADLIBES): Deleted.
732 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
733 * config/m88kcoff.mt (TDEFINES): Ditto.

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

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

820 the 'j' operand if there are no further alternatives for this
823 * config/obj-coffbfd.c (adjust_stab_section): Initialize
824 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
825 is not SEG_UNKNOWN rather than checking whether it is >= 0.
827 * config/tc-mips.c (mips_align): Take new argument, label, and use
828 it instead of global insn_label.
829 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
830 call to mips_emit_delay and pass it to mips_align.
832 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
834 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
836 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
837 argument to a .callinfo directive. Don't loop forever on errors.
839 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
840 use pre-defined registers as arguments.
842 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
844 * write.c (write_object_file): Check both S_IS_LOCAL and
845 S_IS_EXTERNAL when deciding whether to discard a symbol.
847 * config-gas.com: Scan Makefile.in, not version.c, for current
848 version number. Delete all versions of temp files when finished
849 with them. Create config.h.
851 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
852 values to reduce number of lookups with S_GET_VALUE. Skip debug

854 holger@botbso.rhein-main.de.)
855 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
856 field. (Also from Holger Teutsch.) Watch for a would-be register
857 mask that spans frags.
859 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
860 this_base, not line_base. (Patch from Andreas Arens,
861 ari@obelix.av.rwth-aachen.de.)
863 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
864 look local if they're exported or undefined. Used to be done for
867 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
868 Get it from the looked-up symbol, instead of using the string from
869 the input stream, which is no longer null-terminated.

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

934 (obj_coff_section): Declare.
935 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
936 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2388 frag of type rs_machine_dependent rather than looking through
2391 * read.c (read_a_source_file): If we find a bad pseudo-op,
2392 do a continue to go on to the next line rather than a break.

2403 a zero size section.
2405 * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, base
2406 data offset on reloc[0]->address rather than reloc[j]->address, so

2410 adjust_reloc_syms, write_relocs): Make third argument PTR, not
2411 char *, to match definition of bfd_map_over_sections.

2622 an example of marker relocations.
2623 * write.c (write_relocs): Instead of assuming size of a relocation
2624 is 4 bytes, pick up the size from relocation itself.

2654 pass new argument for i, j and o cases.

2876 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2877 the table, require that the one without bit 0x1000000 set come
2878 first. Require further that it be case 'b' or 'P'. The a29k
2879 opcode table already meets these constraints.
2880 (machine_ip): When handling case 'i' or 'A', make sure that the

2929 as.info* even if they're in $(srcdir) (e.g., for FSF
2932 * write.c (write_relocs): For relocs that are pc_relative and
2933 pcrel_offset and not partial_inplace, adjust reloc->addend to
2934 compensate for a bfd_perform_relocation bug.
2936 * config/tc-sparc.h: Removed remaining non-BFD_ASSEMBLER code.

2989 for keeping or rejecting configurations still under development;
2990 default is to assume production environment, and reject configs
2991 still being worked on. Mark Elf configurations (except sparc and
2992 i386) as developmental. Deleted cases matching some generic names
2993 in favor of more specific names. (E.g., when we get Alpha
2994 support, we'll still only support VMS for Vax.)

3010 through inclusion of tc-hppa.h. Delete all forward declarations
3011 for functions only used within tc-hppa.c, likewise for structures,
3012 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3013 conditional code in a few small places.
3015 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3016 structures, global variables, forward declarations together.
3017 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
3018 conditional code -- try to group conditional code together
3019 into a few places. Make all functions and variables which
3020 are only used within tc-hppa.c static. PARAMize all functions.
3021 Add comments to functions. Delete unused functions, variables,
3022 #defines, etc. Delete unused members within structures. Delete
3023 ldil;ble hacks -- it is believed they were installed to work
3024 around old gas bugs. Avoid using mixed case for local
3025 functions, variables, and structures. Fix formatting problems
3026 not found by GNU-indent. Add FIXME notices for things which
3027 should be worked on the near future. Delete lots of old
3028 useless (1.36 PA-SOM) code.

3045 * config/tc-hppa.c: Likewise.
3047 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3048 of elf32_symbol_type.
3049 (pa_export_args): Likewise.
3050 (elf_hppa_final_processing): Likewise.

3056 * config/tc-hppa.c: (md_section_align): Align all sections to
3057 a multiple of the section alignment rather than always a
3060 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3061 bits are zero (eg they specify no relocations), then do not even
3062 bother adding their entries to thesymextn section.

3091 * config/tc-i386.c (md_apply_fix_1): Make cross segment calls work
3092 for ELF by hacking around bizarre bfd_perform_relocation behaviour
3093 that I don't dare change.

3100 of text, data and bss sections to 4.
3101 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3103 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3104 ELF, since the ELF object format does not have these type of
3105 relocations. Change the abort into as as_bad and return
3106 BFD_RELOC_NONE to silence compiler warnings.
3107 (md_assemble): Keep track of the instruction size. Allow white
3108 space between the $ and the constant for compatibility with older
3109 gases and other assemblers.
3110 (i386_operand): Skip spaces between $ and expression.
3111 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5498 avoid some redefinition complaints on some systems.

5543 dropping a space immediately following an identifier.

5546 * config/tc-mips.c (macro): Use $AT if target register is zero in
5547 load instruction, which it can be for a floating point load.

5673 * read.c (s_ignore): Don't declare is_end_of_line. It's
5674 redundant, and triggers a VMS gcc compiler bug.

5998 For now, only accept "no", until the merge is done.
6000 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6001 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
6002 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
6003 * read.c: Finish conversion to S_* macros in the VMS only
6004 parts of the program. Add "const" modifier to hex_value.

6007 * expr.c: Add "const" modifier to hex_value.
6008 * symbols.c: Finish conversion to S_* macros in the VMS only
6009 parts of the program. Add "const" modifier to
6010 md_[long,short]_jump_size. Remove declaration of const_flag
6011 (which will be declared in obj-vms.h).
6012 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6013 Fix arguments to VMS_write_object_file.
6014 * config-gas.com: New file. Script for VMS systems to set up the
6015 configuration to build gas for VMS, and create config.status.

6074 mapping to segT enum values.
6075 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6076 if these are used or defined, if BFD_ASSEMBLER.
6077 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6078 subseg_new split into two functions.
6079 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6081 * as.h (volatile): Don't define if already defined.
6082 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6093 <mtranle@paris.intellicorp.com>.
6094 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6095 obj_format coffbfd and gas_target i386coff for target.
6096 (i[34]86-*-isc*): New host (uses sysv).
6097 * config/i386aix.mt: Removed (no longer used).
6098 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6100 (LDFLAGS): Added, defined as -shlib.
6101 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6102 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6103 (DOT_LABEL_PREFIX): Define.
6104 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6105 name rather than L0\001.
6106 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6108 * symbols.c, symbols.h (local_bss_counter): Removed.
6109 * write.c (write_object_file): bss no longer uses
6110 local_bss_counter. Pass correct data and bss size to
6111 VMS_write_object_file.
6112 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
6113 argument, rather than using local_bss_counter.

6117 (size_section): Restored sanity check.
6118 (do_relocs_for): Base section address on s_paddr rather than
6119 computing it. Adjust a29k R_IHIHALF special case to account for
6120 section paddr (used to require paddr to be zero). If there are no
6121 reclos, set s_relptr to 0. Set relocation size in object_headers.
6122 (fill_section): Always set s_vaddr here, removing
6123 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6124 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6125 Set STYP_INFO for .comment.

6130 (do_linenos_for): Set lineno size in object_headers.
6131 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6132 set s_vaddr here. If string_byte_count remains 4, set it back to
6133 0, and only write strings out if there are some. Call
6134 fill_section before do_relocs_for and do_linenos_for.
6135 (obj_coff_section): Handle optional quoted second argument giving
6136 section characteristics.
6137 (obj_coff_bss): Added to handle .bss.
6138 (obj_coff_ident): Added to handle .ident (puts string in .comment
6140 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6141 (fixup_mdeps): Change to segment. Call frag_wane after
6143 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6144 adjustment (already happened only for common symbols, but this is
6146 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
6147 * config/tc-i386.c (s_bss): Don't use if I386COFF.

6158 (do_scrub_next_char): For \", return " not '.
6159 (symbol_chars): Now const.
6161 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6162 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6164 * config/obj-coff.h: Don't use #elif.
6166 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6167 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6169 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6194 using ZERO_BASED_SEGMENTS.
6195 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6196 never set segment address for SEG_E2 (.bss) and don't write out
6197 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6198 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6199 definitions, and don't merge tags with non-tags. Check for .bf
6200 rather than just checking whether the second character is b and
6201 the third character is f.
6202 (obj_coff_val): gcc can generate values which we don't handle
6203 correctly; discard information for now, since it only affects the
6204 debugging information.
6205 (tag_find_or_name): Don't insert tags in the symbol table.
6206 (yank_symbols): Don't merge labels.
6207 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6210 (obj_coff_section): Accept and ignore a trailing quoted string, as
6211 used in AT&T i386 syntax.
6212 (fixup_segment): Take segment as argument. On the i386, adjust PC
6213 relative addends by the segment vaddr.
6214 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6215 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6352 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6353 could be doing emulation.
6355 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6358 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6361 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

6387 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6389 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6390 constant will not fit in an immediate field.
6391 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6410 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
6411 so widening works consistently.
6413 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)

6426 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6428 * Support for i386-sysv.
6429 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6453 * tc-m68k.c (get_num): make it work for all segments, not just the
6456 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6458 * configure.in: recognize i386-*-bsd emulation.

6467 * tc-z8k.c: lots of bug fixes
6469 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6471 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6472 #elif, since it is not supported by old compilers.
6473 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6474 couple of expressions in tc-m68k.c.
6476 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6478 * read.c (cons): If NO_RELOC is defined, use it.
6480 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6482 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6484 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6485 local labels to start with a .) and set REGISTER_PREFIX to %.
6486 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6488 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6490 * messages.c: Comment changes.
6492 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6495 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6497 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6499 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6502 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6504 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6505 sections starting from zero, rather than making them consecutive.
6506 This makes subsequent reloc calculations easier, esp if the object
6507 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6508 allocate lcomm in .data rather than in .bss. It seems that some
6509 tools can't cope with a non-zero sized bss before linkage.
6511 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6513 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6514 throughout. That enum no longer means what we thought it meant.
6516 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6517 "-mno-688[58]1" options.
6519 * tc-m68k.c: Added CPU32 support.
6521 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

6527 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6528 Change LIBDEPS dependence to LIBS.
6530 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6532 * Makefile.in (install): if $(tooldir) exists, install as in
6535 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6537 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6538 .word is < -32768 or > 32767. The -J flag causes the error to be
6539 ignored. This is to catch over-sized switches generated by gcc on
6540 systems which don't support the broken .word hack.
6541 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6542 write.c (fixup_segment): check for signed .word overflow if
6543 WARN_SIGNED_OVERFLOW_WORD.
6545 * write.c (fixup_segment): fixed missing parens in expression
6546 checking for byte or word overflow.
6548 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6549 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6550 WARN_SIGNED_OVERFLOW_WORD.

6558 * obj-coffbfd.h : added stuff
6559 * tc-i386.c (tc_coff_fix2rtype): new function
6560 * tc-i386.h : new coff defines
6562 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6564 * input-scrub.c (input_scrub_push): call input_file_begin, not
6566 messages.c (as_perror): print ": " between the passed in error and
6567 the strerror, like perror does.
6569 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6571 * Makefile.in: use gas_target instead of modifying target_cpu.
6572 From Steve Chamberlain:
6573 Makefile.in: Handle m68*-*-coff*.
6574 read.c, read.h: add mult argument to s_space
6576 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6577 Motorola and MIT syntax; gas can now assemble either type of
6579 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6659 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6660 written with indirection on the last two operands, which can be
6661 either data or address registers. Added a new operand type 'r'
6662 which accepts either register type. Added '(' to notend stuff in
6663 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7006 really strange things with things like fbge,a
7008 * as.h: include bfd.h if using many sections
7009 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

7018 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7020 * app.c: MRI compatibility - allow single quote to start a string.

7022 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7023 * expr.c: Much rewriting, to accomodate MRI syntax for
7024 expressions. Also easier to read now.
7025 * listing.c: Put back defuns
7026 * read.c: modified to accept MRI syntax, put back listing pseudo
7027 ops so that an assembler built with NO_LISTING ignores list ops
7029 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7030 machine is a SPARC or a 29K.
7031 * config/obj-aout.c: added s_sect pseudo op
7032 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7033 fill in the timestamp.
7034 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7035 anymore, define all the relocs which the tc-<x> bit will use so we
7036 can translate from them to the coff types.
7037 * config/tc-a29k.c: reloc_type isn't ane enum any more
7038 * config/tc-m68k.c: Added NO_RELOC definition.

7057 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7058 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7059 generate these sections. .align: will use NOP_OPCODE or 0
7060 for padding. This is just for being nice to the
7063 * expr.c (operand): changed to generate local label "\001L0"
7064 starting with a ^A so that it is recognized as a local label.
7066 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7068 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7069 i/o opcodes - inb, inw, outb and outw. string manipulation with
7070 att syntax - scmp, slod, smov, ssca, ssto.
7072 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7073 to just after .file .
7075 In obj_crawl_symbol_chain() where it tries to put the external
7076 symbols apart, with the condition:

7080 it was moving too many symbols out. So I switch it back to the
7082 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7084 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7085 so that we don't use the F_RELFLG which make the linker complain
7086 that somebody has stripped the relocation info.
7088 Also, the AIX ld program require that the relocation table
7089 is sorted by r_vaddr like the standard ATT assembler does.
7091 [he also changed the sizeof(struct ...)'s into the coff
7092 style FOOSZ macros. I'm not sure this is right, but I can't

7102 * read.c: white space and comments only.
7104 * configure.in: use the new atof-ns32.c for ns32k.
7106 * write.c: comment change only.
7108 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7109 aren't yet integrated.
7111 * tc-i860.[hc]: blew off the dust. Something must still be done
7112 about conflicting relocation types.
7114 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7117 * tc-i960.c, tc-sparc.c: white space and comments only.
7119 * tc-a29k.h: delete duplicate macro definition.
7121 * new file atof-ns32k.c copied from hack's last unreleased gas.

7125 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7128 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7129 ChangeLog's prior to this are sketchy at best. I have logs.
7130 They just aren't ChangeLogs.
