509 (obj_frob_symbol): Call elf_frob_symbol always, rather than
510 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.
511 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
513 (obj_elf_size): Deleted unused code. If size is non-reducible

644 (print_expr_1): Fix whitespace before printing X_add_number.
646 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
647 not symbol_new, for symbols holding expression values.
648 * expr.h (make_expr_symbol): Move declaration here.
649 * write.c (fix_new_exp): Handle O_add by creating an
650 expression-valued symbol, and calling fix_new_exp recursively.
651 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
652 undefined symbol and a constant, fold the constant into the fixup,
653 and refer to the undefined symbol directly. Then process the
654 fixup again from scratch.
655 (write_object_file): Before calling adjust_reloc_syms, make a pass
656 through the symbol list trying to resolve values.
658 * write.c (print_fixup): New routine, for debugging.
659 (write_relocs): Call bfd_install_relocation. Deleted various
660 hacks for working around problems with bfd_perform_relocation.

677 * write.c (write_relocs): Add file name and line number to
678 as_fatal calls. Handle bfd_reloc_overflow case specifically when
679 RELOC_EXPANSION_POSSIBLE.
681 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
683 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
684 here. Use them for deciding which PRINTF*LIKE macro definitions
686 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
687 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
688 default definitions matching what we were doing before.
689 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
690 always use the varargs form if not using stdarg. It's safe to
691 always use vfprintf, because libiberty will provide it if the
692 native system doesn't. Also, always make format be const.
693 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

708 (listing_newline): Check filename as well as line number when
709 deciding whether to record it.
710 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
711 false (if defined) as well as checking for reg_section.
712 (listing_listing): Iterate fetching lines while line number is too
713 low, and we haven't run off the end of the input file.
715 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
717 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

742 (brtab_emit): Use data_section, not SEG_DATA.
744 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
746 * config/vms-conf.h: new file, manually derived from conf.in.
747 * config-gas.com: use it, and eliminate obsolete "host.h".

757 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
758 from the csect of the enclosing block.
760 * config/tc-mips.c (insns_since_cache_access): Remove.

766 * config/tc-mips.c (md_shortopts): Remove E.
767 (md_longopts): Add EB and EL.
768 (md_parse_option): Handle -EB and -EL as separate options, rather
769 than as a single -E option with an argument.
771 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
773 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
774 involving global symbols too.
776 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
778 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
780 * configure.in: Test for remove, not delete. Fix cross-assembler

792 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
793 many others): new macros; values obtained from "DSTRECRDS.SDL".
794 * config/obj-vms.h (various): use them.
795 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
796 representation (only enum bitfields can avoid being bitstrings).
797 (bitfield_suffix, setup_basic_type): new routines.
798 (VMS_typedef_parse): use them. Now recognize bitfields of all
799 integral types, not just type `int'. Caveat: the representation
800 used for bitfields still does not work for objects placed in
801 registers, and gcc's optimizer sometimes puts small structs there.
803 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
805 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
807 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
808 (tc_frob_label): define this to call vms_check_for_special_label,
809 and declare the latter.

812 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
813 (vms_check_for_special_label): new routine (tc_frob_label).
814 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
815 and `gcc2_compiled.' labels; they won't reach here any more.
816 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
817 double', use `vax_g_doubles' flag to select type of double.
818 (VMS_write_object_file) [traceback setup]: don't pass symbols
819 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
820 and TBT_Routine_End functions.
822 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
824 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
825 S_GET_VALUE() to avoid many repeated function calls.
826 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
827 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
828 gets requested. [All the HACK_DEC_C_STARTUP code appears to
829 be obsolete; gcc does it automatically for vms target. It's
830 also misnamed, because it is for the "VAX C" run-time library,
831 not the newer "DEC C" one which has much different startup code.]
832 {various}: use `S_SET_xxx(symbol,new_value)' rather than
833 `S_GET_xxx(symbol) = new_value'.

837 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

842 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
844 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
846 * expr.c (expr): Don't reduce the difference of two symbols in the
847 same frag if the symbols are not in normal sections.
849 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
850 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
851 (obj_attach_unwind_info): Do not define. Not needed anymore.
852 * config/tc-hppa.c: Delete whitespace at EOL.
853 (struct hppa_fix_struct): Delete fx_unwind field and all references.
854 (fix_new_hppa): Last arg is now a pointer to an int. Do not
855 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
856 fixups, store 32bits of unwind information in the fx_addnumber
858 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
859 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
860 pointer to 32 bits of unwind info.
861 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
862 pointer to the dummy symbol; set the addend field to fx_addnumber.
863 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
864 rather than &bfd_XXX_section.
866 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
868 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
869 value by one; discard adjustments previously being made. From
872 VMS- and Vax-related changes from Pat Rankin:
873 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
874 * vmsconf.sh: no longer have make-gas.com echo text about needing
875 to modify the gcc-vms driver when intending to use with gcc 1.x.
876 * as.c (parse_options): suppress 'v' from std_short_options and
877 eliminate VMS-specific conditional initialization;
878 [default case]: check for '-v' if md_parse_options doesn't recognize

882 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
883 for O_big literal operands (double floats and long long ints);
884 [VMS, md_shortopts]: add second colon after 'v';
885 (md_parse_options) [VMS, case 'v']: check for argument, so
886 caller can handle `-v' w/o arg.

931 Rewrite handling of program_transform_name.
933 * configure.in: Test for functions unlink and delete.
934 * as.h: If unlink isn't available but delete is, define unlink to
937 Update for autoconf 1.118:
938 * gdbinit.in: New file, created from old .gdbinit.
940 * aclocal.m4 (GAS_GDBINIT): Deleted.
941 * configure.in: Don't use it. Instead, generate .gdbinit from
942 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
943 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
944 to ensure that older versions of autoconf aren't used.

956 * aclocal.m4 (GAS_GDBINIT): New macro.

970 PIC implementation for i386-linux, based on code from Eric
971 Youngdale and Paul Kranenburg, with some work of my own:
973 * write.c (fixup_segment): Test TC_RELOC_RTSYM_LOC_FIXUP on fixup
974 before processing same-section pcrel relocations.

2379 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2381 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2383 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2384 source files from other directories into objects in the current
2385 directory, and specify PSECT attributes explicitly to linker.
2386 Also added missing label.
2387 * Makefile.in (stamp-mk.com): Reference new variable

2405 argument, the reloc type.
2406 (load_register): Pass reloc type to macro_build for 'u'.
2407 (macro): Likewise. For M_LA_AB permit a difference expression
2408 when generating embedded PIC code between an arbitrary symbol and
2409 a symbol in the .text section.
2410 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2411 BFD_RELOC_PCREL_LO16 to be emitted.

2419 * subsegs.c (subsegs_begin): Call memset with args in the correct
2421 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2422 to NULL instead of 0.

2426 * config/tc-hppa.c (pa_procend): Handle case where label was
2427 defined after the .proc directive.
2429 * config/tc-hppa.c (pa_procend): Give an error if we encounter a

2451 (hppa_tc_symbol): Likewise.
2453 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2454 elf_tc_make_sections stuff. It was there to support PA braindamage
2455 which has been fixed, and in the case of elf_tc_make_sections is
2456 redundant with elf_tc_final_processing.
2458 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2460 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2476 don't spew remainder of input file in error message.
2477 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2478 message with reloc type and try to process remainder of file.
2480 * doc/Makefile.in (install-info-as, install-info-gasp): New
2481 targets, now explicitly checking $(srcdir) for info files.
2482 (install-info): Depend on both of them; do nothing more.

2486 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2488 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2490 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2491 flag rather than signedp field. Only permit extended range if
2492 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2493 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2495 * config/tc-ppc.c (ppc_size): New static variable.
2496 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2497 (md_begin): If an instruction has a size specific flag set, only
2498 add it if we are assembling that size.
2500 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2502 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2503 cross section PC relative relocs right for COFF and ELF.
2505 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2507 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2508 (OBJ_PROCESS_STAB): Don't define.

2512 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2513 the type of symbol set symbols which happen to be in the absolute
2514 or undefined section.

2518 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2519 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2520 and -many (all architectures).
2522 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2524 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2525 involving a function symbol which is not a plabel to zero.
2526 (md_apply_fix): Never pass a function symbol to field_adjust.
2528 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2530 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2531 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2533 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2534 branch with an instruction that uses $at, in case the branch is
2536 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2537 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2538 to make it pcrel_offset.
2539 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2540 reloc->address; another gruesome hack to get gas reloc handling to
2543 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2545 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2548 (emit_insn): New function.
2549 (md_assemble): Call it.
2550 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2552 (lituse_pending): New variable. Set by anything that generates a
2553 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2554 tested by code that might want to emit a LITUSE reloc.
2555 (emit_unaligned_io): New function. Currently calls md_assemble,
2556 but it should eventually be converted to generate the insn itself
2557 and call emit_insn directly.
2558 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2559 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2560 emit_bis_r): Likewise.
2561 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2562 (alpha_ip, label get_macro): Don't emit the final instruction if
2564 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2565 unaligned memory access macros.
2566 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2567 the value can't be resolved.
2569 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2571 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2572 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2573 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2575 (mips_force_relocation): New function.
2576 (md_apply_fix): Set fixP->fx_done appropriately.
2577 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2585 * config/tc-mips.c (enum mips_pic_level): New enum.
2586 (mips_pic): Change from int to enum mips_pic_level. Change all
2587 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2588 (load_address): Handle EMBEDDED_PIC.
2589 (macro): Handle EMBEDDED_PIC in all PIC cases.
2590 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2591 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2592 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2593 works). Do not permit -G with SVR4_PIC.
2594 (s_abicalls): Warn if -G was used, and force -G 0.
2595 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2596 anything but a.out, not just for ELF. For ECOFF, don't generate a
2597 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2599 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2601 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2603 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2604 parameters to avoid losing when compiling with HP CC.
2605 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2607 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2609 * Makefile.in (config-stamp): If `defs' is defined, emit a
2610 preprocessor directive to create a macro named by this value into
2611 config.new; don't explicitly go for BFD_ASSEMBLER.
2612 * configure.in: Define `defs', not `BFDDEF'. Set it to
2613 MANY_SEGMENTS for any obj-coffbfd target.
2614 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2615 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2617 (LOCAL_LOADLIBES): Deleted.
2618 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2619 * config/m88kcoff.mt (TDEFINES): Ditto.
2620 * config/ebmon29k.mt: Deleted.
2621 * config/h8300hds.mt: Deleted.

2645 bfd_set_symtab is called.
2646 (dump_section_relocs): Note whether a symbol is a section symbol
2648 (adjust_reloc_syms): For now, always supply an absolute symbol for
2649 fixups without symbols but not yet `done'. Use section_symbol to
2650 get the symbol, instead of going directly for abs_symbol.
2651 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2652 reloc is not a section symbol and is not in the symbol table.
2653 (set_symtab): New function, broken out from write_object_file.
2654 Counts symbol table instead of relying on an earlier count.
2655 (write_object_file): Call set_symtab, but do it after potentially
2656 invoking the *_frob_file macros. Don't bother counting symbols.
2657 Call symbol_remove, instead of expanding it in place. Moved the
2658 conditionalized `object_file_size' declaration down to
2659 conditionalized block where it's used. When using the absolute
2660 symbol for a fixup without a symbol, set sy_used_in_reloc.
2661 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2662 the correct symbol for the absolute section.
2664 * subsegs.c (section_symbol): Use symbol_new instead of
2665 symbol_make, since we may want it to go into the symbol table.
2666 Make the new symbol have internal linkage. If
2667 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2668 symbol with the newly created GAS symbol.
2669 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2670 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2675 (in_signed_range): New function.
2677 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2678 (sparc_ip, label "immediate"): Reject constants for pcrel
2679 instructions only if the relocation type indicates a "call"
2680 instruction and the offset is within range of a "jmpl %g0". If
2681 it's not in range, use the absolute section symbol plus an offset.
2682 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2684 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2686 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2689 * configure.in: Eliminated all targets using obj-coff but not
2690 defining BFD_ASSEMBLER; I think all such targets that are
2691 supported will be matched by real CPU-OS combinations earlier in
2693 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2694 some comments about the dpx2 configuration, but left it disabled,
2695 since it couldn't be reached before.
2696 (target a29k-amd-ebmonold): Deleted.
2698 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2706 the 'j' operand if there are no further alternatives for this
2709 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2710 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2711 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2713 * config/tc-mips.c (mips_align): Take new argument, label, and use
2714 it instead of global insn_label.
2715 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2716 call to mips_emit_delay and pass it to mips_align.
2718 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2720 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2722 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2723 argument to a .callinfo directive. Don't loop forever on errors.
2725 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2726 use pre-defined registers as arguments.

2731 S_IS_EXTERNAL when deciding whether to discard a symbol.
2733 * config-gas.com: Scan Makefile.in, not version.c, for current

2735 with them. Create config.h.
2737 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2738 values to reduce number of lookups with S_GET_VALUE. Skip debug
2739 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2740 holger@botbso.rhein-main.de.)
2741 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2742 field. (Also from Holger Teutsch.) Watch for a would-be register
2743 mask that spans frags.
2745 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2746 this_base, not line_base. (Patch from Andreas Arens,
2747 ari@obelix.av.rwth-aachen.de.)
2749 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2750 look local if they're exported or undefined. Used to be done for
2753 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2754 Get it from the looked-up symbol, instead of using the string from
2755 the input stream, which is no longer null-terminated.
2756 (LEX_PCT): New macro, defaults to 0.
2757 (lex_type): Use it for `%'.
2759 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2760 (vip_op): Now static, and returns void. Callers changed. Added
2762 (vip): Ditto. Call as_fatal directly if a program bug is

2809 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2810 0xffff for 'j' to be compatible with MIPS assembler. These
2811 numbers are actually treated as negative.

4512 an example of marker relocations.
4513 * write.c (write_relocs): Instead of assuming size of a relocation
4514 is 4 bytes, pick up the size from relocation itself.

4766 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4767 the table, require that the one without bit 0x1000000 set come
4768 first. Require further that it be case 'b' or 'P'. The a29k
4769 opcode table already meets these constraints.
4770 (machine_ip): When handling case 'i' or 'A', make sure that the
4771 appropriate opcode really exists by looking at the next entry in

4826 * write.c (write_relocs): For relocs that are pc_relative and
4827 pcrel_offset and not partial_inplace, adjust reloc->addend to

4880 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4882 * configure.in: Set bfd_gas for all sparc targets. Added facility
4883 for keeping or rejecting configurations still under development;
4884 default is to assume production environment, and reject configs
4885 still being worked on. Mark Elf configurations (except sparc and
4886 i386) as developmental. Deleted cases matching some generic names
4887 in favor of more specific names. (E.g., when we get Alpha

4904 through inclusion of tc-hppa.h. Delete all forward declarations
4905 for functions only used within tc-hppa.c, likewise for structures,
4906 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4907 conditional code in a few small places.
4909 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4910 structures, global variables, forward declarations together.

4912 conditional code -- try to group conditional code together
4913 into a few places. Make all functions and variables which
4914 are only used within tc-hppa.c static. PARAMize all functions.
4915 Add comments to functions. Delete unused functions, variables,
4916 #defines, etc. Delete unused members within structures. Delete
4917 ldil;ble hacks -- it is believed they were installed to work
4918 around old gas bugs. Avoid using mixed case for local
4919 functions, variables, and structures. Fix formatting problems
4920 not found by GNU-indent. Add FIXME notices for things which
4921 should be worked on the near future. Delete lots of old
4922 useless (1.36 PA-SOM) code.
4924 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4925 field of the fixS structure. Needed to build unwind
4926 descriptors correctly.

4951 a multiple of the section alignment rather than always a
4954 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4955 bits are zero (eg they specify no relocations), then do not even
4956 bother adding their entries to thesymextn section.

5000 of text, data and bss sections to 4.
5001 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5003 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5004 ELF, since the ELF object format does not have these type of
5005 relocations. Change the abort into as as_bad and return
5006 BFD_RELOC_NONE to silence compiler warnings.
5007 (md_assemble): Keep track of the instruction size. Allow white
5008 space between the $ and the constant for compatibility with older
5009 gases and other assemblers.
5010 (i386_operand): Skip spaces between $ and expression.

6054 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6055 case to set obj_format=elf. Must go before i386-*-sysv* case that
6056 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6057 *-*-solaris case, and move to before *-sysv* case that wants to
6058 set obj_format to coff.

6084 * Extensive changes to permit symbols to contain any expression
6085 type and to delay the computation of the expression until the
6086 value is actually needed. This permits setting symbols to values
6087 calculated based on object code size. Expressions were changed to
6088 no longer be in a section, to stop the overloading of segment and
6089 expression type that previously occurred.
6091 * as.c (big_section, pass1_section, diff_section, absent_section):
6093 (expr_section): Added (used for dummy symbols which hold

6177 (previous_section, previous_subsection): New vars.
6178 (obj_elf_section): Save current place in case DWARF code wants us
6179 to pop back to it. Handle unquoted section name as well as quoted
6180 section name. Don't crash on invalid strings.
6181 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6184 * config/obj-elf.h: Don't include struc-symbol.h.

6293 sy_resolved and sy_resolving single bit fields.
6294 * symbols.c (symbol_new): Don't initialize sy_forward field.

7621 * make-gas.com: Find obstack.obj if it's not in the current
7623 * read.c (s_ignore): Don't declare is_end_of_line. It's
7624 redundant, and triggers a VMS gcc compiler bug.
7626 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7627 current segment as an argument. (Ignored in all cases but VMS.)
7628 All callers and definitions changed.

7652 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7655 * configure.in: mips-bsd configuration was missing format spec.
7658 * Makefile.in (Makefile): Depends on configure.in.

7683 generate the latter currently.
7685 * frags.c (frag_init): New function.
7686 (zero_address_frag, bss_address_frag): Now initialized at run
7688 * as.c (main): Call frag_init.

7964 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7965 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7966 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7967 * read.c: Finish conversion to S_* macros in the VMS only
7968 parts of the program. Add "const" modifier to hex_value.
7969 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7971 * expr.c: Add "const" modifier to hex_value.
7972 * symbols.c: Finish conversion to S_* macros in the VMS only
7973 parts of the program. Add "const" modifier to
7974 md_[long,short]_jump_size. Remove declaration of const_flag
7975 (which will be declared in obj-vms.h).
7976 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7977 Fix arguments to VMS_write_object_file.
7978 * config-gas.com: New file. Script for VMS systems to set up the
7979 configuration to build gas for VMS, and create config.status.
7980 * make-gas.com: Redone to work with new scheme.
7981 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7983 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7984 will swap bytes if needed on a big endian system. Use throughout
7986 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7987 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7988 types of malformed stabs. Change parsing algorithm so that we are
7989 more certain of having all of the information that we need on hand.
7990 * obj-vms.c (final_forward_reference): New function, used to help
7991 resolve the data types of as many struct elements as possible
7992 when some part of the struct is not fully defined by the compiler.
7993 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7995 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7996 as symbols as well in the object file. Look for external functions
7997 that start with "__vt.", and turn them into variables, since the
7998 g++ compiler is incapable of doing this.
7999 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8001 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8002 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8003 have the name of the source file yet.
8004 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8006 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8008 * read.c (s_data): Always use "data_section", since it'll map to
8009 SEG_DATA or SEG_E1 if needed.
8010 (s_lcomm): Likewise with bss_section.
8011 (s_fill): Use memset, not bzero.
8013 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8015 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

8029 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8030 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8034 (section_alignment): Declare only if not BFD_ASSEMBLER.
8035 (big_section, reg_section, pass1_section, diff_section,
8036 absent_section, text_section, data_section, bss_section): If
8037 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8038 mapping to segT enum values.
8039 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8040 if these are used or defined, if BFD_ASSEMBLER.
8041 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8042 subseg_new split into two functions.
8043 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8045 * as.h (volatile): Don't define if already defined.
8046 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8048 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8049 declare with format attribute for -Wformat checking.
8051 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8053 * app.c, config/tc-*.c: Don't include read.h, since it is already
8056 * These are based on patches from Minh Tran-le
8057 <mtranle@paris.intellicorp.com>.
8058 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8059 obj_format coffbfd and gas_target i386coff for target.
8060 (i[34]86-*-isc*): New host (uses sysv).
8061 * config/i386aix.mt: Removed (no longer used).
8062 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8064 (LDFLAGS): Added, defined as -shlib.
8065 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8066 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8067 (DOT_LABEL_PREFIX): Define.
8068 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8069 name rather than L0\001.
8070 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8072 * symbols.c, symbols.h (local_bss_counter): Removed.
8073 * write.c (write_object_file): bss no longer uses

8081 (size_section): Restored sanity check.
8082 (do_relocs_for): Base section address on s_paddr rather than
8083 computing it. Adjust a29k R_IHIHALF special case to account for
8084 section paddr (used to require paddr to be zero). If there are no
8085 reclos, set s_relptr to 0. Set relocation size in object_headers.
8086 (fill_section): Always set s_vaddr here, removing
8087 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8088 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8089 Set STYP_INFO for .comment.

8093 H_{SET,GET}_* macros.
8094 (do_linenos_for): Set lineno size in object_headers.
8095 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8096 set s_vaddr here. If string_byte_count remains 4, set it back to
8097 0, and only write strings out if there are some. Call
8098 fill_section before do_relocs_for and do_linenos_for.
8099 (obj_coff_section): Handle optional quoted second argument giving
8100 section characteristics.
8101 (obj_coff_bss): Added to handle .bss.
8102 (obj_coff_ident): Added to handle .ident (puts string in .comment

8122 (do_scrub_next_char): For \", return " not '.
8123 (symbol_chars): Now const.
8125 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8126 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8128 * config/obj-coff.h: Don't use #elif.
8130 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8131 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8157 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8158 using ZERO_BASED_SEGMENTS.
8159 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8160 never set segment address for SEG_E2 (.bss) and don't write out
8161 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8162 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8163 definitions, and don't merge tags with non-tags. Check for .bf
8164 rather than just checking whether the second character is b and
8165 the third character is f.
8166 (obj_coff_val): gcc can generate values which we don't handle
8167 correctly; discard information for now, since it only affects the
8168 debugging information.

8170 (yank_symbols): Don't merge labels.
8171 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8435 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8436 #elif, since it is not supported by old compilers.
8437 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8438 couple of expressions in tc-m68k.c.
8440 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8442 * read.c (cons): If NO_RELOC is defined, use it.
8444 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8446 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8448 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8449 local labels to start with a .) and set REGISTER_PREFIX to %.
8450 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8452 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8463 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8466 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8468 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8469 sections starting from zero, rather than making them consecutive.
8470 This makes subsequent reloc calculations easier, esp if the object
8471 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8472 allocate lcomm in .data rather than in .bss. It seems that some
8473 tools can't cope with a non-zero sized bss before linkage.
8475 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8477 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8478 throughout. That enum no longer means what we thought it meant.

8481 "-mno-688[58]1" options.
8483 * tc-m68k.c: Added CPU32 support.

8496 * Makefile.in (install): if $(tooldir) exists, install as in
8499 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8501 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8502 .word is < -32768 or > 32767. The -J flag causes the error to be
8503 ignored. This is to catch over-sized switches generated by gcc on
8504 systems which don't support the broken .word hack.
8505 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8506 write.c (fixup_segment): check for signed .word overflow if
8507 WARN_SIGNED_OVERFLOW_WORD.
8509 * write.c (fixup_segment): fixed missing parens in expression
8510 checking for byte or word overflow.

8526 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8528 * input-scrub.c (input_scrub_push): call input_file_begin, not
8530 messages.c (as_perror): print ": " between the passed in error and
8531 the strerror, like perror does.
8533 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8535 * Makefile.in: use gas_target instead of modifying target_cpu.
8536 From Steve Chamberlain:
8537 Makefile.in: Handle m68*-*-coff*.
8538 read.c, read.h: add mult argument to s_space
8540 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8541 Motorola and MIT syntax; gas can now assemble either type of
8543 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8549 (write_object_file) call fixup_mdeps
8550 (fixup_segment) set fx_subsy to 0.
8551 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8553 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8556 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8558 * Makefile.in (LIBS): Include opcode library.

8583 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8585 * config/tc-m68k.c (init_table): Now const. Always include 68851
8586 data, so that "bc" is available to 68040 cache instructions.
8587 Added "tt0", "tt1", and 68ec030 variants.
8588 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8589 (enum _register): Added TT0, TT1.
8590 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8591 line number correctly in "internal error" messages. Don't print
8592 architecture-mismatch message for operand errors.
8594 From Colin Smith (colin@wrs.com):
8595 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8596 than install_operand.

8617 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8618 has already been formatted (but may still contain %-characters).
8621 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8623 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8624 written with indirection on the last two operands, which can be
8625 either data or address registers. Added a new operand type 'r'
8626 which accepts either register type. Added '(' to notend stuff in
8627 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8927 * doc/Makefile.in: commented out line for building as-all.texinfo.
8930 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8932 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8934 * Makefile.in: added check target.
8936 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8938 * Makefile.in: added tooldir and program_prefix.
8940 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8942 * write.{c,h} (fix_new): Make these declarations consistent.
8944 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8946 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8949 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8951 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8953 * expr.c (operand): if can't work out what sort of operand it is,
8954 then look through FLT_CHARS for a hint.
8956 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8958 * Makefile.in, configure.in: removed traces of namesubdir,
8959 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8960 copyrights to '92, changed some from Cygnus to FSF.
8962 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8963 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8964 copyrights to '92, changed some from Cygnus to FSF.
8966 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8968 * expr.c: If an expression is single comma, then return with
8969 SEG_ABSENT rather than an error - since the sparc front end does
8970 really strange things with things like fbge,a
8972 * as.h: include bfd.h if using many sections
8973 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8974 local labels didn't work.
8975 * listing.c (list_symbol_table): don't core dump when there's no
8977 * write.c, write.h: call fix_new with the right number of args on
8979 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8982 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8984 * app.c: MRI compatibility - allow single quote to start a string.
8985 * as.c: fix typo recently introduced.
8986 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8987 * expr.c: Much rewriting, to accomodate MRI syntax for
8988 expressions. Also easier to read now.
8989 * listing.c: Put back defuns
8990 * read.c: modified to accept MRI syntax, put back listing pseudo
8991 ops so that an assembler built with NO_LISTING ignores list ops
8993 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8994 machine is a SPARC or a 29K.
8995 * config/obj-aout.c: added s_sect pseudo op
8996 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8997 fill in the timestamp.
8998 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8999 anymore, define all the relocs which the tc-<x> bit will use so we
9000 can translate from them to the coff types.
9001 * config/tc-a29k.c: reloc_type isn't ane enum any more
9002 * config/tc-m68k.c: Added NO_RELOC definition.
9004 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9006 * Makefile.in: put header files before C source for TAGS; remove
9007 references to non-existent syscalls.h.
9009 * read.c, write.c subsegs.c: back out the .bss changes.
9011 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9013 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9017 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9019 * symbols.c (local_label_name): symbols now start with ^A.
9021 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9022 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9023 generate these sections. .align: will use NOP_OPCODE or 0
9024 for padding. This is just for being nice to the
9027 * expr.c (operand): changed to generate local label "\001L0"
9028 starting with a ^A so that it is recognized as a local label.
9030 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9032 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9033 i/o opcodes - inb, inw, outb and outw. string manipulation with
9034 att syntax - scmp, slod, smov, ssca, ssto.
9036 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9037 to just after .file .
9039 In obj_crawl_symbol_chain() where it tries to put the external
9040 symbols apart, with the condition:
9041 (!S_IS_DEFINED(symbolP) &&
9042 !S_IS_DEBUG(symbolP) &&
9043 !SF_GET_STATICS(symbolP))
9044 it was moving too many symbols out. So I switch it back to the
9046 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9048 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9049 so that we don't use the F_RELFLG which make the linker complain
9050 that somebody has stripped the relocation info.
9052 Also, the AIX ld program require that the relocation table
9053 is sorted by r_vaddr like the standard ATT assembler does.
9055 [he also changed the sizeof(struct ...)'s into the coff
9056 style FOOSZ macros. I'm not sure this is right, but I can't
9057 remember why. xoxorich.]
9059 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9061 * Makefile.in, configure.in, doc: use the doc. Build it, install
9064 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9066 * read.c: white space and comments only.
9068 * configure.in: use the new atof-ns32.c for ns32k.
9070 * write.c: comment change only.
9072 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9073 aren't yet integrated.
9075 * tc-i860.[hc]: blew off the dust. Something must still be done
9076 about conflicting relocation types.
9078 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9081 * tc-i960.c, tc-sparc.c: white space and comments only.
9083 * tc-a29k.h: delete duplicate macro definition.
9085 * new file atof-ns32k.c copied from hack's last unreleased gas.
9087 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9089 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9092 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9093 ChangeLog's prior to this are sketchy at best. I have logs.
9094 They just aren't ChangeLogs.
