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

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

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

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

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

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

789 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
790 many others): new macros; values obtained from "DSTRECRDS.SDL".
791 * config/obj-vms.h (various): use them.

793 representation (only enum bitfields can avoid being bitstrings).
794 (bitfield_suffix, setup_basic_type): new routines.
795 (VMS_typedef_parse): use them. Now recognize bitfields of all
796 integral types, not just type `int'. Caveat: the representation
797 used for bitfields still does not work for objects placed in
798 registers, and gcc's optimizer sometimes puts small structs there.
800 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
802 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
804 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
805 (tc_frob_label): define this to call vms_check_for_special_label,
806 and declare the latter.

809 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.

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

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

839 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
841 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
843 * expr.c (expr): Don't reduce the difference of two symbols in the
844 same frag if the symbols are not in normal sections.
846 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
847 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.

849 * config/tc-hppa.c: Delete whitespace at EOL.
850 (struct hppa_fix_struct): Delete fx_unwind field and all references.
851 (fix_new_hppa): Last arg is now a pointer to an int. Do not
852 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
853 fixups, store 32bits of unwind information in the fx_addnumber
855 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
856 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
857 pointer to 32 bits of unwind info.
858 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
859 pointer to the dummy symbol; set the addend field to fx_addnumber.
860 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
861 rather than &bfd_XXX_section.
863 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
865 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
866 value by one; discard adjustments previously being made. From
869 VMS- and Vax-related changes from Pat Rankin:
870 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
871 * vmsconf.sh: no longer have make-gas.com echo text about needing
872 to modify the gcc-vms driver when intending to use with gcc 1.x.
873 * as.c (parse_options): suppress 'v' from std_short_options and
874 eliminate VMS-specific conditional initialization;
875 [default case]: check for '-v' if md_parse_options doesn't recognize

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

934 Update for autoconf 1.118:
935 * gdbinit.in: New file, created from old .gdbinit.
937 * aclocal.m4 (GAS_GDBINIT): Deleted.
938 * configure.in: Don't use it. Instead, generate .gdbinit from
939 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
940 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
941 to ensure that older versions of autoconf aren't used.

2376 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2378 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2380 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2381 source files from other directories into objects in the current
2382 directory, and specify PSECT attributes explicitly to linker.
2383 Also added missing label.
2384 * Makefile.in (stamp-mk.com): Reference new variable

2400 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2401 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2402 argument, the reloc type.
2403 (load_register): Pass reloc type to macro_build for 'u'.
2404 (macro): Likewise. For M_LA_AB permit a difference expression
2405 when generating embedded PIC code between an arbitrary symbol and
2406 a symbol in the .text section.
2407 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2408 BFD_RELOC_PCREL_LO16 to be emitted.

2416 * subsegs.c (subsegs_begin): Call memset with args in the correct
2418 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2419 to NULL instead of 0.

2423 * config/tc-hppa.c (pa_procend): Handle case where label was
2424 defined after the .proc directive.
2426 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2427 procend for a procedure without a name.

2448 (hppa_tc_symbol): Likewise.
2450 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2451 elf_tc_make_sections stuff. It was there to support PA braindamage
2452 which has been fixed, and in the case of elf_tc_make_sections is
2453 redundant with elf_tc_final_processing.
2455 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2457 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2473 don't spew remainder of input file in error message.
2474 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2475 message with reloc type and try to process remainder of file.
2477 * doc/Makefile.in (install-info-as, install-info-gasp): New
2478 targets, now explicitly checking $(srcdir) for info files.
2479 (install-info): Depend on both of them; do nothing more.

2483 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2485 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2487 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2488 flag rather than signedp field. Only permit extended range if
2489 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2490 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2492 * config/tc-ppc.c (ppc_size): New static variable.
2493 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2494 (md_begin): If an instruction has a size specific flag set, only
2495 add it if we are assembling that size.
2497 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2499 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2500 cross section PC relative relocs right for COFF and ELF.
2502 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2504 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2505 (OBJ_PROCESS_STAB): Don't define.
2507 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2509 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2510 the type of symbol set symbols which happen to be in the absolute
2511 or undefined section.
2513 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2515 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2516 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2517 and -many (all architectures).
2519 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2521 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2522 involving a function symbol which is not a plabel to zero.
2523 (md_apply_fix): Never pass a function symbol to field_adjust.
2525 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2527 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2528 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2530 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2531 branch with an instruction that uses $at, in case the branch is
2533 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2534 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2535 to make it pcrel_offset.
2536 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2537 reloc->address; another gruesome hack to get gas reloc handling to
2540 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2542 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2545 (emit_insn): New function.
2546 (md_assemble): Call it.
2547 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2549 (lituse_pending): New variable. Set by anything that generates a
2550 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2551 tested by code that might want to emit a LITUSE reloc.
2552 (emit_unaligned_io): New function. Currently calls md_assemble,
2553 but it should eventually be converted to generate the insn itself
2554 and call emit_insn directly.
2555 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2556 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2557 emit_bis_r): Likewise.
2558 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2559 (alpha_ip, label get_macro): Don't emit the final instruction if
2561 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2562 unaligned memory access macros.
2563 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2564 the value can't be resolved.
2566 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2568 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2569 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2570 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2572 (mips_force_relocation): New function.
2573 (md_apply_fix): Set fixP->fx_done appropriately.
2574 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2582 * config/tc-mips.c (enum mips_pic_level): New enum.
2583 (mips_pic): Change from int to enum mips_pic_level. Change all
2584 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2585 (load_address): Handle EMBEDDED_PIC.
2586 (macro): Handle EMBEDDED_PIC in all PIC cases.
2587 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2588 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2589 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2590 works). Do not permit -G with SVR4_PIC.
2591 (s_abicalls): Warn if -G was used, and force -G 0.
2592 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2593 anything but a.out, not just for ELF. For ECOFF, don't generate a
2594 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2596 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2598 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2600 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2601 parameters to avoid losing when compiling with HP CC.
2602 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2604 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2606 * Makefile.in (config-stamp): If `defs' is defined, emit a
2607 preprocessor directive to create a macro named by this value into
2608 config.new; don't explicitly go for BFD_ASSEMBLER.
2609 * configure.in: Define `defs', not `BFDDEF'. Set it to
2610 MANY_SEGMENTS for any obj-coffbfd target.
2611 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2612 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2614 (LOCAL_LOADLIBES): Deleted.
2615 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2616 * config/m88kcoff.mt (TDEFINES): Ditto.
2617 * config/ebmon29k.mt: Deleted.
2618 * config/h8300hds.mt: Deleted.
2619 * config/ic960coff.mt: Deleted.
2620 * config/sparc.mt: Deleted.
2621 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2622 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2623 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2624 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

2642 bfd_set_symtab is called.
2643 (dump_section_relocs): Note whether a symbol is a section symbol
2645 (adjust_reloc_syms): For now, always supply an absolute symbol for
2646 fixups without symbols but not yet `done'. Use section_symbol to
2647 get the symbol, instead of going directly for abs_symbol.
2648 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2649 reloc is not a section symbol and is not in the symbol table.
2650 (set_symtab): New function, broken out from write_object_file.
2651 Counts symbol table instead of relying on an earlier count.
2652 (write_object_file): Call set_symtab, but do it after potentially
2653 invoking the *_frob_file macros. Don't bother counting symbols.
2654 Call symbol_remove, instead of expanding it in place. Moved the
2655 conditionalized `object_file_size' declaration down to
2656 conditionalized block where it's used. When using the absolute
2657 symbol for a fixup without a symbol, set sy_used_in_reloc.
2658 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2659 the correct symbol for the absolute section.
2661 * subsegs.c (section_symbol): Use symbol_new instead of
2662 symbol_make, since we may want it to go into the symbol table.
2663 Make the new symbol have internal linkage. If
2664 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2665 symbol with the newly created GAS symbol.
2666 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2667 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2669 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.

2672 (in_signed_range): New function.
2674 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2675 (sparc_ip, label "immediate"): Reject constants for pcrel
2676 instructions only if the relocation type indicates a "call"
2677 instruction and the offset is within range of a "jmpl %g0". If
2678 it's not in range, use the absolute section symbol plus an offset.
2679 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2681 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2683 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2686 * configure.in: Eliminated all targets using obj-coff but not
2687 defining BFD_ASSEMBLER; I think all such targets that are
2688 supported will be matched by real CPU-OS combinations earlier in
2690 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2691 some comments about the dpx2 configuration, but left it disabled,
2692 since it couldn't be reached before.
2693 (target a29k-amd-ebmonold): Deleted.
2695 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2703 the 'j' operand if there are no further alternatives for this
2706 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2707 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2708 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2710 * config/tc-mips.c (mips_align): Take new argument, label, and use
2711 it instead of global insn_label.
2712 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2713 call to mips_emit_delay and pass it to mips_align.
2715 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2717 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2719 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2720 argument to a .callinfo directive. Don't loop forever on errors.
2722 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2723 use pre-defined registers as arguments.

2727 * write.c (write_object_file): Check both S_IS_LOCAL and
2728 S_IS_EXTERNAL when deciding whether to discard a symbol.
2730 * config-gas.com: Scan Makefile.in, not version.c, for current
2731 version number. Delete all versions of temp files when finished
2732 with them. Create config.h.
2734 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2735 values to reduce number of lookups with S_GET_VALUE. Skip debug
2736 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2737 holger@botbso.rhein-main.de.)
2738 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2739 field. (Also from Holger Teutsch.) Watch for a would-be register
2740 mask that spans frags.
2742 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2743 this_base, not line_base. (Patch from Andreas Arens,
2744 ari@obelix.av.rwth-aachen.de.)
2746 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2747 look local if they're exported or undefined. Used to be done for
2750 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2751 Get it from the looked-up symbol, instead of using the string from
2752 the input stream, which is no longer null-terminated.
2753 (LEX_PCT): New macro, defaults to 0.
2754 (lex_type): Use it for `%'.
2756 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2757 (vip_op): Now static, and returns void. Callers changed. Added
2759 (vip): Ditto. Call as_fatal directly if a program bug is

2806 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2807 0xffff for 'j' to be compatible with MIPS assembler. These
2808 numbers are actually treated as negative.
2810 Thu Mar 10 13:36:29 1994 Doug Evans (dje@canuck.cygnus.com)
2812 * config/tc-sparc.h (LOCAL_LABEL): Local labels are .Lfoo.

2817 (obj_coff_section): Declare.
2818 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
2819 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

4219 information is known. Added PIC support for all symbol
4221 (mips_ip): Don't permit anything but a number after $ for a
4222 coprocessor register. Don't use .lit4 or .lit8 sections when

4391 Delete dead code. Simplify.
4392 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4393 applied are in range. Use bfd_put_32 rather than inserting each

4472 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4473 standard hpux include files to pick up various function decls.
4475 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4509 an example of marker relocations.
4510 * write.c (write_relocs): Instead of assuming size of a relocation
4511 is 4 bytes, pick up the size from relocation itself.

4541 pass new argument for i, j and o cases.
4542 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4763 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4764 the table, require that the one without bit 0x1000000 set come
4765 first. Require further that it be case 'b' or 'P'. The a29k
4766 opcode table already meets these constraints.
4767 (machine_ip): When handling case 'i' or 'A', make sure that the
4768 appropriate opcode really exists by looking at the next entry in

4823 * write.c (write_relocs): For relocs that are pc_relative and
4824 pcrel_offset and not partial_inplace, adjust reloc->addend to

4877 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4879 * configure.in: Set bfd_gas for all sparc targets. Added facility
4880 for keeping or rejecting configurations still under development;
4881 default is to assume production environment, and reject configs
4882 still being worked on. Mark Elf configurations (except sparc and
4883 i386) as developmental. Deleted cases matching some generic names
4884 in favor of more specific names. (E.g., when we get Alpha

4901 through inclusion of tc-hppa.h. Delete all forward declarations
4902 for functions only used within tc-hppa.c, likewise for structures,
4903 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4904 conditional code in a few small places.
4906 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4907 structures, global variables, forward declarations together.

4909 conditional code -- try to group conditional code together
4910 into a few places. Make all functions and variables which
4911 are only used within tc-hppa.c static. PARAMize all functions.
4912 Add comments to functions. Delete unused functions, variables,
4913 #defines, etc. Delete unused members within structures. Delete
4914 ldil;ble hacks -- it is believed they were installed to work
4915 around old gas bugs. Avoid using mixed case for local
4916 functions, variables, and structures. Fix formatting problems
4917 not found by GNU-indent. Add FIXME notices for things which
4918 should be worked on the near future. Delete lots of old
4919 useless (1.36 PA-SOM) code.
4921 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4922 field of the fixS structure. Needed to build unwind
4923 descriptors correctly.

4947 * config/tc-hppa.c: (md_section_align): Align all sections to
4948 a multiple of the section alignment rather than always a
4951 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4952 bits are zero (eg they specify no relocations), then do not even
4953 bother adding their entries to thesymextn section.

4957 * config/tc-sparc.c (md_parse_option): Accept and ignore -sparc

4996 instead add a second loop over special_chars. Set alignment
4997 of text, data and bss sections to 4.
4998 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5000 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5001 ELF, since the ELF object format does not have these type of
5002 relocations. Change the abort into as as_bad and return
5003 BFD_RELOC_NONE to silence compiler warnings.
5004 (md_assemble): Keep track of the instruction size. Allow white
5005 space between the $ and the constant for compatibility with older
5006 gases and other assemblers.
5007 (i386_operand): Skip spaces between $ and expression.

6053 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6054 *-*-solaris case, and move to before *-sysv* case that wants to
6055 set obj_format to coff.

6081 * Extensive changes to permit symbols to contain any expression
6082 type and to delay the computation of the expression until the
6083 value is actually needed. This permits setting symbols to values
6084 calculated based on object code size. Expressions were changed to
6085 no longer be in a section, to stop the overloading of segment and
6086 expression type that previously occurred.
6088 * as.c (big_section, pass1_section, diff_section, absent_section):
6090 (expr_section): Added (used for dummy symbols which hold

6174 (previous_section, previous_subsection): New vars.
6175 (obj_elf_section): Save current place in case DWARF code wants us
6176 to pop back to it. Handle unquoted section name as well as quoted
6177 section name. Don't crash on invalid strings.
6178 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6181 * config/obj-elf.h: Don't include struc-symbol.h.

6290 sy_resolved and sy_resolving single bit fields.
6291 * symbols.c (symbol_new): Don't initialize sy_forward field.

7618 * make-gas.com: Find obstack.obj if it's not in the current
7620 * read.c (s_ignore): Don't declare is_end_of_line. It's
7621 redundant, and triggers a VMS gcc compiler bug.
7623 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7624 current segment as an argument. (Ignored in all cases but VMS.)
7625 All callers and definitions changed.

7649 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7652 * configure.in: mips-bsd configuration was missing format spec.
7655 * Makefile.in (Makefile): Depends on configure.in.
7657 * config/tc-mips.c (append_insn): Don't check for alignment of
7658 frag in memory; alignment of instructions in section is a separate

7679 constants are accepted, but symbolic values are not. GCC will not
7680 generate the latter currently.
7682 * frags.c (frag_init): New function.
7683 (zero_address_frag, bss_address_frag): Now initialized at run
7685 * as.c (main): Call frag_init.

7961 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7962 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7963 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7964 * read.c: Finish conversion to S_* macros in the VMS only
7965 parts of the program. Add "const" modifier to hex_value.
7966 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7968 * expr.c: Add "const" modifier to hex_value.
7969 * symbols.c: Finish conversion to S_* macros in the VMS only
7970 parts of the program. Add "const" modifier to
7971 md_[long,short]_jump_size. Remove declaration of const_flag
7972 (which will be declared in obj-vms.h).
7973 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7974 Fix arguments to VMS_write_object_file.
7975 * config-gas.com: New file. Script for VMS systems to set up the
7976 configuration to build gas for VMS, and create config.status.
7977 * make-gas.com: Redone to work with new scheme.
7978 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7980 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7981 will swap bytes if needed on a big endian system. Use throughout
7983 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7984 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7985 types of malformed stabs. Change parsing algorithm so that we are
7986 more certain of having all of the information that we need on hand.
7987 * obj-vms.c (final_forward_reference): New function, used to help
7988 resolve the data types of as many struct elements as possible
7989 when some part of the struct is not fully defined by the compiler.
7990 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7992 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7993 as symbols as well in the object file. Look for external functions
7994 that start with "__vt.", and turn them into variables, since the
7995 g++ compiler is incapable of doing this.
7996 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7998 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7999 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8000 have the name of the source file yet.
8001 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8003 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8005 * read.c (s_data): Always use "data_section", since it'll map to
8006 SEG_DATA or SEG_E1 if needed.
8007 (s_lcomm): Likewise with bss_section.
8008 (s_fill): Use memset, not bzero.
8010 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8012 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
8013 handling GDB symbol table data.

8026 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8027 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8031 (section_alignment): Declare only if not BFD_ASSEMBLER.
8032 (big_section, reg_section, pass1_section, diff_section,
8033 absent_section, text_section, data_section, bss_section): If
8034 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8035 mapping to segT enum values.
8036 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8037 if these are used or defined, if BFD_ASSEMBLER.
8038 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8039 subseg_new split into two functions.
8040 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8042 * as.h (volatile): Don't define if already defined.
8043 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8045 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8046 declare with format attribute for -Wformat checking.
8048 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8050 * app.c, config/tc-*.c: Don't include read.h, since it is already
8053 * These are based on patches from Minh Tran-le
8054 <mtranle@paris.intellicorp.com>.
8055 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8056 obj_format coffbfd and gas_target i386coff for target.
8057 (i[34]86-*-isc*): New host (uses sysv).
8058 * config/i386aix.mt: Removed (no longer used).
8059 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8061 (LDFLAGS): Added, defined as -shlib.
8062 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8063 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8064 (DOT_LABEL_PREFIX): Define.
8065 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8066 name rather than L0\001.
8067 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8069 * symbols.c, symbols.h (local_bss_counter): Removed.
8070 * write.c (write_object_file): bss no longer uses

8077 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
8078 (size_section): Restored sanity check.
8079 (do_relocs_for): Base section address on s_paddr rather than
8080 computing it. Adjust a29k R_IHIHALF special case to account for
8081 section paddr (used to require paddr to be zero). If there are no
8082 reclos, set s_relptr to 0. Set relocation size in object_headers.
8083 (fill_section): Always set s_vaddr here, removing
8084 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8085 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8086 Set STYP_INFO for .comment.

8090 H_{SET,GET}_* macros.
8091 (do_linenos_for): Set lineno size in object_headers.
8092 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8093 set s_vaddr here. If string_byte_count remains 4, set it back to
8094 0, and only write strings out if there are some. Call
8095 fill_section before do_relocs_for and do_linenos_for.
8096 (obj_coff_section): Handle optional quoted second argument giving
8097 section characteristics.
8098 (obj_coff_bss): Added to handle .bss.
8099 (obj_coff_ident): Added to handle .ident (puts string in .comment

8119 (do_scrub_next_char): For \", return " not '.
8120 (symbol_chars): Now const.
8122 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8123 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8125 * config/obj-coff.h: Don't use #elif.
8127 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8128 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8154 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8155 using ZERO_BASED_SEGMENTS.
8156 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8157 never set segment address for SEG_E2 (.bss) and don't write out
8158 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8159 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8160 definitions, and don't merge tags with non-tags. Check for .bf
8161 rather than just checking whether the second character is b and
8162 the third character is f.
8163 (obj_coff_val): gcc can generate values which we don't handle
8164 correctly; discard information for now, since it only affects the
8165 debugging information.

8167 (yank_symbols): Don't merge labels.
8168 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8432 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8433 #elif, since it is not supported by old compilers.
8434 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8435 couple of expressions in tc-m68k.c.
8437 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8439 * read.c (cons): If NO_RELOC is defined, use it.
8441 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8443 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8445 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8446 local labels to start with a .) and set REGISTER_PREFIX to %.
8447 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8449 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8460 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8463 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8465 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8466 sections starting from zero, rather than making them consecutive.
8467 This makes subsequent reloc calculations easier, esp if the object
8468 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8469 allocate lcomm in .data rather than in .bss. It seems that some
8470 tools can't cope with a non-zero sized bss before linkage.
8472 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8474 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8475 throughout. That enum no longer means what we thought it meant.

8478 "-mno-688[58]1" options.
8480 * tc-m68k.c: Added CPU32 support.

8493 * Makefile.in (install): if $(tooldir) exists, install as in
8496 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8498 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8499 .word is < -32768 or > 32767. The -J flag causes the error to be
8500 ignored. This is to catch over-sized switches generated by gcc on
8501 systems which don't support the broken .word hack.
8502 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8503 write.c (fixup_segment): check for signed .word overflow if
8504 WARN_SIGNED_OVERFLOW_WORD.
8506 * write.c (fixup_segment): fixed missing parens in expression
8507 checking for byte or word overflow.
8509 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

8523 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8525 * input-scrub.c (input_scrub_push): call input_file_begin, not
8527 messages.c (as_perror): print ": " between the passed in error and
8528 the strerror, like perror does.
8530 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8532 * Makefile.in: use gas_target instead of modifying target_cpu.
8533 From Steve Chamberlain:
8534 Makefile.in: Handle m68*-*-coff*.
8535 read.c, read.h: add mult argument to s_space
8537 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8538 Motorola and MIT syntax; gas can now assemble either type of
8540 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8546 (write_object_file) call fixup_mdeps
8547 (fixup_segment) set fx_subsy to 0.
8548 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8550 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8553 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8555 * Makefile.in (LIBS): Include opcode library.

8578 little endian byte order (used to use endianness of host).
8580 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8582 * config/tc-m68k.c (init_table): Now const. Always include 68851
8583 data, so that "bc" is available to 68040 cache instructions.
8584 Added "tt0", "tt1", and 68ec030 variants.
8585 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8586 (enum _register): Added TT0, TT1.
8587 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8588 line number correctly in "internal error" messages. Don't print
8589 architecture-mismatch message for operand errors.
8591 From Colin Smith (colin@wrs.com):
8592 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8593 than install_operand.

8614 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8615 has already been formatted (but may still contain %-characters).
8618 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8620 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8621 written with indirection on the last two operands, which can be
8622 either data or address registers. Added a new operand type 'r'
8623 which accepts either register type. Added '(' to notend stuff in
8624 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8924 * doc/Makefile.in: commented out line for building as-all.texinfo.
8927 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8929 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8931 * Makefile.in: added check target.
8933 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8935 * Makefile.in: added tooldir and program_prefix.
8937 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8939 * write.{c,h} (fix_new): Make these declarations consistent.
8941 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8943 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8946 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8948 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8950 * expr.c (operand): if can't work out what sort of operand it is,
8951 then look through FLT_CHARS for a hint.
8953 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8955 * Makefile.in, configure.in: removed traces of namesubdir,
8956 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8957 copyrights to '92, changed some from Cygnus to FSF.
8959 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8960 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8961 copyrights to '92, changed some from Cygnus to FSF.
8963 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8965 * expr.c: If an expression is single comma, then return with
8966 SEG_ABSENT rather than an error - since the sparc front end does
8967 really strange things with things like fbge,a
8969 * as.h: include bfd.h if using many sections
8970 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8971 local labels didn't work.
8972 * listing.c (list_symbol_table): don't core dump when there's no
8974 * write.c, write.h: call fix_new with the right number of args on
8976 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8979 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8981 * app.c: MRI compatibility - allow single quote to start a string.
8982 * as.c: fix typo recently introduced.
8983 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8984 * expr.c: Much rewriting, to accomodate MRI syntax for
8985 expressions. Also easier to read now.
8986 * listing.c: Put back defuns
8987 * read.c: modified to accept MRI syntax, put back listing pseudo
8988 ops so that an assembler built with NO_LISTING ignores list ops
8990 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8991 machine is a SPARC or a 29K.
8992 * config/obj-aout.c: added s_sect pseudo op
8993 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8994 fill in the timestamp.
8995 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8996 anymore, define all the relocs which the tc-<x> bit will use so we
8997 can translate from them to the coff types.
8998 * config/tc-a29k.c: reloc_type isn't ane enum any more
8999 * config/tc-m68k.c: Added NO_RELOC definition.
9001 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9003 * Makefile.in: put header files before C source for TAGS; remove
9004 references to non-existent syscalls.h.
9006 * read.c, write.c subsegs.c: back out the .bss changes.
9008 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9010 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9014 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9016 * symbols.c (local_label_name): symbols now start with ^A.
9018 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9019 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9020 generate these sections. .align: will use NOP_OPCODE or 0
9021 for padding. This is just for being nice to the
9024 * expr.c (operand): changed to generate local label "\001L0"
9025 starting with a ^A so that it is recognized as a local label.
9027 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9029 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9030 i/o opcodes - inb, inw, outb and outw. string manipulation with
9031 att syntax - scmp, slod, smov, ssca, ssto.
9033 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9034 to just after .file .
9036 In obj_crawl_symbol_chain() where it tries to put the external
9037 symbols apart, with the condition:
9038 (!S_IS_DEFINED(symbolP) &&
9039 !S_IS_DEBUG(symbolP) &&
9040 !SF_GET_STATICS(symbolP))
9041 it was moving too many symbols out. So I switch it back to the
9043 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9045 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9046 so that we don't use the F_RELFLG which make the linker complain
9047 that somebody has stripped the relocation info.
9049 Also, the AIX ld program require that the relocation table
9050 is sorted by r_vaddr like the standard ATT assembler does.
9052 [he also changed the sizeof(struct ...)'s into the coff
9053 style FOOSZ macros. I'm not sure this is right, but I can't
9054 remember why. xoxorich.]
9056 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9058 * Makefile.in, configure.in, doc: use the doc. Build it, install
9061 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9063 * read.c: white space and comments only.
9065 * configure.in: use the new atof-ns32.c for ns32k.
9067 * write.c: comment change only.
9069 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9070 aren't yet integrated.
9072 * tc-i860.[hc]: blew off the dust. Something must still be done
9073 about conflicting relocation types.
9075 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9078 * tc-i960.c, tc-sparc.c: white space and comments only.
9080 * tc-a29k.h: delete duplicate macro definition.
9082 * new file atof-ns32k.c copied from hack's last unreleased gas.
9084 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9086 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9089 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9090 ChangeLog's prior to this are sketchy at best. I have logs.
9091 They just aren't ChangeLogs.
9098 version-control: never
