512 includes the frag address.
513 (fixup_segment): Changed local var PCREL to type int, added PLT.
514 If PC-relative fixup refers to a PLT entry for a symbol in the
515 current section, don't reduce it.

518 DEBUG5 is defined, print out each fixup before and after
520 (fixup_segment): If DEBUG5 is defined, print out each fixup before
521 and after processing.
522 (print_fixup): Added prototype. Show address on first line. Show
523 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
524 NEED_FX_R_TYPE is defined.

531 * Makefile.in (all): Depend on .gdbinit.
532 (.gdbinit): Rebuild from gdbinit.in by running config.status.
534 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
536 * write.c (print_fixup): Print source location on first line.

547 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
550 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
551 processing if add_symbol is undefined or in expr_section.
552 (resolve_symbol_value, case O_add): For symbol plus
553 constant-valued symbol, convert to O_symbol and re-reduce.
554 (S_GET_VALUE): If symbol needs resolving, resolve it.
555 (indent_level): No longer static.
556 (print_symbol_value_1): Don't print frag address if it matches
557 zero_address_frag. Don't print "resolving" if already resolved.
558 Print segment name. Don't call print_expr_1 on an undefined
560 (print_expr_1): Fix whitespace before printing X_add_number.
562 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
563 not symbol_new, for symbols holding expression values.
564 * expr.h (make_expr_symbol): Move declaration here.
565 * write.c (fix_new_exp): Handle O_add by creating an
566 expression-valued symbol, and calling fix_new_exp recursively.
567 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
568 undefined symbol and a constant, fold the constant into the fixup,
569 and refer to the undefined symbol directly. Then process the
570 fixup again from scratch.
571 (write_object_file): Before calling adjust_reloc_syms, make a pass
572 through the symbol list trying to resolve values.
574 * write.c (print_fixup): New routine, for debugging.
575 (write_relocs): Call bfd_install_relocation. Deleted various
576 hacks for working around problems with bfd_perform_relocation.

584 * config/tc-mips.c: Include subsegs.h.
585 (md_apply_fix): If an unconditional b or bal overflows, and we are
586 not assembling PIC code, replace it with a j or jal.
588 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
589 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
591 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
593 * write.c (write_relocs): Add file name and line number to
594 as_fatal calls. Handle bfd_reloc_overflow case specifically when
595 RELOC_EXPANSION_POSSIBLE.
597 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
599 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
600 here. Use them for deciding which PRINTF*LIKE macro definitions
602 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
603 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
604 default definitions matching what we were doing before.
605 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
606 always use the varargs form if not using stdarg. It's safe to
607 always use vfprintf, because libiberty will provide it if the
608 native system doesn't. Also, always make format be const.
609 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
611 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

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

644 * symbols.c (copy_symbol_attributes): New function. Copies BFD
645 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
646 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
647 zero. Don't call obj_frob_forward_symbol.

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

672 (ppc_es): Clear ppc_current_block.
673 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
674 from the csect of the enclosing block.
676 * config/tc-mips.c (insns_since_cache_access): Remove.
677 (append_insn): Remove setting of insns_since_cache_access, and

680 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
682 * config/tc-mips.c (md_shortopts): Remove E.
683 (md_longopts): Add EB and EL.
684 (md_parse_option): Handle -EB and -EL as separate options, rather
685 than as a single -E option with an argument.
687 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
689 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
690 involving global symbols too.
692 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
694 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
696 * configure.in: Test for remove, not delete. Fix cross-assembler

706 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
708 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
709 many others): new macros; values obtained from "DSTRECRDS.SDL".
710 * config/obj-vms.h (various): use them.
711 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
712 representation (only enum bitfields can avoid being bitstrings).
713 (bitfield_suffix, setup_basic_type): new routines.
714 (VMS_typedef_parse): use them. Now recognize bitfields of all
715 integral types, not just type `int'. Caveat: the representation
716 used for bitfields still does not work for objects placed in
717 registers, and gcc's optimizer sometimes puts small structs there.
719 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
721 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
723 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
724 (tc_frob_label): define this to call vms_check_for_special_label,
725 and declare the latter.
726 * config/obj-vms.c (vax_g_doubles): declare this file-scope
728 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
729 (vms_check_for_special_label): new routine (tc_frob_label).
730 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
731 and `gcc2_compiled.' labels; they won't reach here any more.
732 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
733 double', use `vax_g_doubles' flag to select type of double.
734 (VMS_write_object_file) [traceback setup]: don't pass symbols
735 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
736 and TBT_Routine_End functions.
738 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
740 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
741 S_GET_VALUE() to avoid many repeated function calls.
742 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
743 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
744 gets requested. [All the HACK_DEC_C_STARTUP code appears to
745 be obsolete; gcc does it automatically for vms target. It's
746 also misnamed, because it is for the "VAX C" run-time library,
747 not the newer "DEC C" one which has much different startup code.]
748 {various}: use `S_SET_xxx(symbol,new_value)' rather than
749 `S_GET_xxx(symbol) = new_value'.

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

758 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
760 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
762 * expr.c (expr): Don't reduce the difference of two symbols in the
763 same frag if the symbols are not in normal sections.
765 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
766 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
767 (obj_attach_unwind_info): Do not define. Not needed anymore.
768 * config/tc-hppa.c: Delete whitespace at EOL.
769 (struct hppa_fix_struct): Delete fx_unwind field and all references.
770 (fix_new_hppa): Last arg is now a pointer to an int. Do not
771 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
772 fixups, store 32bits of unwind information in the fx_addnumber
774 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
775 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
776 pointer to 32 bits of unwind info.
777 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
778 pointer to the dummy symbol; set the addend field to fx_addnumber.
779 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
780 rather than &bfd_XXX_section.
782 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
784 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
785 value by one; discard adjustments previously being made. From
788 VMS- and Vax-related changes from Pat Rankin:
789 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
790 * vmsconf.sh: no longer have make-gas.com echo text about needing
791 to modify the gcc-vms driver when intending to use with gcc 1.x.
792 * as.c (parse_options): suppress 'v' from std_short_options and
793 eliminate VMS-specific conditional initialization;
794 [default case]: check for '-v' if md_parse_options doesn't recognize

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

853 Update for autoconf 1.118:
854 * gdbinit.in: New file, created from old .gdbinit.
856 * aclocal.m4 (GAS_GDBINIT): Deleted.
857 * configure.in: Don't use it. Instead, generate .gdbinit from
858 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
859 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
860 to ensure that older versions of autoconf aren't used.

1926 VMS debugger now recognizes `long long' variables correctly.
1927 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1928 for gcc2's predefined types "long double" (same as double, as
1929 per gcc's current state), "long long int", "long long unsigned
1930 int", and final `otherwise' case (to avoid uninitialized type
1931 and size fields). [caveat: predefined types "complex int",
1932 "complex float", "complex double", and "complex long double" are
1935 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1936 of 0, because the latter indicates success rather than failure

2391 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2392 don't spew remainder of input file in error message.
2393 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2394 message with reloc type and try to process remainder of file.

2406 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2407 flag rather than signedp field. Only permit extended range if
2408 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.

2411 * config/tc-ppc.c (ppc_size): New static variable.
2412 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2413 (md_begin): If an instruction has a size specific flag set, only
2414 add it if we are assembling that size.

2418 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2419 cross section PC relative relocs right for COFF and ELF.
2421 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2447 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2449 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2450 branch with an instruction that uses $at, in case the branch is
2452 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

2454 to make it pcrel_offset.
2455 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

2465 (md_assemble): Call it.
2466 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2468 (lituse_pending): New variable. Set by anything that generates a
2469 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2470 tested by code that might want to emit a LITUSE reloc.
2471 (emit_unaligned_io): New function. Currently calls md_assemble,
2472 but it should eventually be converted to generate the insn itself
2473 and call emit_insn directly.
2474 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2475 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2476 emit_bis_r): Likewise.

2487 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2488 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2489 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2504 (load_address): Handle EMBEDDED_PIC.
2505 (macro): Handle EMBEDDED_PIC in all PIC cases.
2506 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2507 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2508 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2509 works). Do not permit -G with SVR4_PIC.
2510 (s_abicalls): Warn if -G was used, and force -G 0.
2511 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2512 anything but a.out, not just for ELF. For ECOFF, don't generate a
2513 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2515 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

2523 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2525 * Makefile.in (config-stamp): If `defs' is defined, emit a
2526 preprocessor directive to create a macro named by this value into
2527 config.new; don't explicitly go for BFD_ASSEMBLER.
2528 * configure.in: Define `defs', not `BFDDEF'. Set it to
2529 MANY_SEGMENTS for any obj-coffbfd target.
2530 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2531 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

2561 bfd_set_symtab is called.
2562 (dump_section_relocs): Note whether a symbol is a section symbol
2564 (adjust_reloc_syms): For now, always supply an absolute symbol for
2565 fixups without symbols but not yet `done'. Use section_symbol to
2566 get the symbol, instead of going directly for abs_symbol.
2567 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2568 reloc is not a section symbol and is not in the symbol table.
2569 (set_symtab): New function, broken out from write_object_file.
2570 Counts symbol table instead of relying on an earlier count.
2571 (write_object_file): Call set_symtab, but do it after potentially
2572 invoking the *_frob_file macros. Don't bother counting symbols.
2573 Call symbol_remove, instead of expanding it in place. Moved the
2574 conditionalized `object_file_size' declaration down to
2575 conditionalized block where it's used. When using the absolute
2576 symbol for a fixup without a symbol, set sy_used_in_reloc.
2577 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2578 the correct symbol for the absolute section.
2580 * subsegs.c (section_symbol): Use symbol_new instead of
2581 symbol_make, since we may want it to go into the symbol table.
2582 Make the new symbol have internal linkage. If
2583 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2584 symbol with the newly created GAS symbol.
2585 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2586 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2591 (in_signed_range): New function.
2593 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2594 (sparc_ip, label "immediate"): Reject constants for pcrel
2595 instructions only if the relocation type indicates a "call"
2596 instruction and the offset is within range of a "jmpl %g0". If
2597 it's not in range, use the absolute section symbol plus an offset.
2598 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2600 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2602 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2605 * configure.in: Eliminated all targets using obj-coff but not
2606 defining BFD_ASSEMBLER; I think all such targets that are
2607 supported will be matched by real CPU-OS combinations earlier in
2609 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2610 some comments about the dpx2 configuration, but left it disabled,
2611 since it couldn't be reached before.
2612 (target a29k-amd-ebmonold): Deleted.
2614 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2622 the 'j' operand if there are no further alternatives for this
2625 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2626 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2627 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2629 * config/tc-mips.c (mips_align): Take new argument, label, and use
2630 it instead of global insn_label.
2631 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2632 call to mips_emit_delay and pass it to mips_align.
2634 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2636 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2638 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2639 argument to a .callinfo directive. Don't loop forever on errors.
2641 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2642 use pre-defined registers as arguments.

2646 * write.c (write_object_file): Check both S_IS_LOCAL and
2647 S_IS_EXTERNAL when deciding whether to discard a symbol.
2649 * config-gas.com: Scan Makefile.in, not version.c, for current
2650 version number. Delete all versions of temp files when finished
2651 with them. Create config.h.
2653 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2654 values to reduce number of lookups with S_GET_VALUE. Skip debug
2655 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2656 holger@botbso.rhein-main.de.)
2657 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2658 field. (Also from Holger Teutsch.) Watch for a would-be register
2659 mask that spans frags.
2661 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2662 this_base, not line_base. (Patch from Andreas Arens,
2663 ari@obelix.av.rwth-aachen.de.)
2665 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2666 look local if they're exported or undefined. Used to be done for
2669 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2670 Get it from the looked-up symbol, instead of using the string from
2671 the input stream, which is no longer null-terminated.
2672 (LEX_PCT): New macro, defaults to 0.
2673 (lex_type): Use it for `%'.
2675 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2676 (vip_op): Now static, and returns void. Callers changed. Added

2725 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2726 0xffff for 'j' to be compatible with MIPS assembler. These

4799 for keeping or rejecting configurations still under development;
4800 default is to assume production environment, and reject configs
4801 still being worked on. Mark Elf configurations (except sparc and
4802 i386) as developmental. Deleted cases matching some generic names
4803 in favor of more specific names. (E.g., when we get Alpha

4829 into a few places. Make all functions and variables which
4830 are only used within tc-hppa.c static. PARAMize all functions.
4831 Add comments to functions. Delete unused functions, variables,
4832 #defines, etc. Delete unused members within structures. Delete
4833 ldil;ble hacks -- it is believed they were installed to work
4834 around old gas bugs. Avoid using mixed case for local
4835 functions, variables, and structures. Fix formatting problems
4836 not found by GNU-indent. Add FIXME notices for things which
4837 should be worked on the near future. Delete lots of old
4838 useless (1.36 PA-SOM) code.

4857 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4858 of elf32_symbol_type.
4859 (pa_export_args): Likewise.

4867 a multiple of the section alignment rather than always a
4870 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

4917 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4919 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4920 ELF, since the ELF object format does not have these type of
4921 relocations. Change the abort into as as_bad and return
4922 BFD_RELOC_NONE to silence compiler warnings.
4923 (md_assemble): Keep track of the instruction size. Allow white
4924 space between the $ and the constant for compatibility with older
4925 gases and other assemblers.

7369 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7376 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

7409 dropping a space immediately following an identifier.

7411 lines; I don't think that can be done portably.
7412 * config/tc-mips.c (macro): Use $AT if target register is zero in

7537 * make-gas.com: Find obstack.obj if it's not in the current
7539 * read.c (s_ignore): Don't declare is_end_of_line. It's
7540 redundant, and triggers a VMS gcc compiler bug.
7542 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7543 current segment as an argument. (Ignored in all cases but VMS.)
7544 All callers and definitions changed.

7602 (zero_address_frag, bss_address_frag): Now initialized at run
7604 * as.c (main): Call frag_init.

7875 (operand): Treat zero byte as end-of-operand.
7877 * configure.in (per-target): Look for with_bfd_assembler option.
7878 For now, only accept "no", until the merge is done.
7880 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7881 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7882 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7883 * read.c: Finish conversion to S_* macros in the VMS only
7884 parts of the program. Add "const" modifier to hex_value.
7885 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7887 * expr.c: Add "const" modifier to hex_value.
7888 * symbols.c: Finish conversion to S_* macros in the VMS only
7889 parts of the program. Add "const" modifier to
7890 md_[long,short]_jump_size. Remove declaration of const_flag
7891 (which will be declared in obj-vms.h).
7892 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7893 Fix arguments to VMS_write_object_file.
7894 * config-gas.com: New file. Script for VMS systems to set up the
7895 configuration to build gas for VMS, and create config.status.

7903 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7904 types of malformed stabs. Change parsing algorithm so that we are
7905 more certain of having all of the information that we need on hand.

7911 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7912 as symbols as well in the object file. Look for external functions

7914 g++ compiler is incapable of doing this.
7915 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7917 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7918 * input-scrub.c (as_where): Fix bug where as would crash if we did not

7925 SEG_DATA or SEG_E1 if needed.
7926 (s_lcomm): Likewise with bss_section.
7927 (s_fill): Use memset, not bzero.

7956 if these are used or defined, if BFD_ASSEMBLER.
7957 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7958 subseg_new split into two functions.
7959 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7961 * as.h (volatile): Don't define if already defined.
7962 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7964 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7965 declare with format attribute for -Wformat checking.
7967 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7969 * app.c, config/tc-*.c: Don't include read.h, since it is already
7972 * These are based on patches from Minh Tran-le
7973 <mtranle@paris.intellicorp.com>.
7974 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7975 obj_format coffbfd and gas_target i386coff for target.
7976 (i[34]86-*-isc*): New host (uses sysv).
7977 * config/i386aix.mt: Removed (no longer used).
7978 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7980 (LDFLAGS): Added, defined as -shlib.
7981 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7982 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7983 (DOT_LABEL_PREFIX): Define.
7984 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7985 name rather than L0\001.
7986 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7988 * symbols.c, symbols.h (local_bss_counter): Removed.
7989 * write.c (write_object_file): bss no longer uses
7990 local_bss_counter. Pass correct data and bss size to
7991 VMS_write_object_file.

7995 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
7996 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7997 (size_section): Restored sanity check.
7998 (do_relocs_for): Base section address on s_paddr rather than
7999 computing it. Adjust a29k R_IHIHALF special case to account for
8000 section paddr (used to require paddr to be zero). If there are no
8001 reclos, set s_relptr to 0. Set relocation size in object_headers.
8002 (fill_section): Always set s_vaddr here, removing
8003 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8004 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8005 Set STYP_INFO for .comment.

8009 H_{SET,GET}_* macros.
8010 (do_linenos_for): Set lineno size in object_headers.
8011 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8012 set s_vaddr here. If string_byte_count remains 4, set it back to
8013 0, and only write strings out if there are some. Call
8014 fill_section before do_relocs_for and do_linenos_for.
8015 (obj_coff_section): Handle optional quoted second argument giving
8016 section characteristics.
8017 (obj_coff_bss): Added to handle .bss.
8018 (obj_coff_ident): Added to handle .ident (puts string in .comment
8020 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8021 (fixup_mdeps): Change to segment. Call frag_wane after
8023 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8024 adjustment (already happened only for common symbols, but this is
8026 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8038 (do_scrub_next_char): For \", return " not '.
8039 (symbol_chars): Now const.
8041 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8042 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8044 * config/obj-coff.h: Don't use #elif.
8046 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8047 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8074 using ZERO_BASED_SEGMENTS.
8075 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8076 never set segment address for SEG_E2 (.bss) and don't write out
8077 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8078 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8079 definitions, and don't merge tags with non-tags. Check for .bf
8080 rather than just checking whether the second character is b and
8081 the third character is f.
8082 (obj_coff_val): gcc can generate values which we don't handle
8083 correctly; discard information for now, since it only affects the
8084 debugging information.

8086 (yank_symbols): Don't merge labels.
8087 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8233 could be doing emulation.
8235 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8238 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8267 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8269 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8270 constant will not fit in an immediate field.
8271 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8306 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8308 * Support for i386-sysv.
8309 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8333 * tc-m68k.c (get_num): make it work for all segments, not just the
8336 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8338 * configure.in: recognize i386-*-bsd emulation.

8347 * tc-z8k.c: lots of bug fixes
8349 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8351 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8352 #elif, since it is not supported by old compilers.
8353 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8354 couple of expressions in tc-m68k.c.
8356 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8358 * read.c (cons): If NO_RELOC is defined, use it.
8360 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8362 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8364 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8365 local labels to start with a .) and set REGISTER_PREFIX to %.
8366 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8368 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8370 * messages.c: Comment changes.
8372 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8379 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8382 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8384 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8385 sections starting from zero, rather than making them consecutive.
8386 This makes subsequent reloc calculations easier, esp if the object
8387 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8388 allocate lcomm in .data rather than in .bss. It seems that some
8389 tools can't cope with a non-zero sized bss before linkage.
8391 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8393 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8394 throughout. That enum no longer means what we thought it meant.
8396 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8397 "-mno-688[58]1" options.
8399 * tc-m68k.c: Added CPU32 support.
8401 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

8407 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8408 Change LIBDEPS dependence to LIBS.
8410 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8412 * Makefile.in (install): if $(tooldir) exists, install as in
8415 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8417 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8418 .word is < -32768 or > 32767. The -J flag causes the error to be
8419 ignored. This is to catch over-sized switches generated by gcc on
8420 systems which don't support the broken .word hack.
8421 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8422 write.c (fixup_segment): check for signed .word overflow if
8423 WARN_SIGNED_OVERFLOW_WORD.
8425 * write.c (fixup_segment): fixed missing parens in expression
8426 checking for byte or word overflow.
8428 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8429 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

8438 * obj-coffbfd.h : added stuff
8439 * tc-i386.c (tc_coff_fix2rtype): new function
8440 * tc-i386.h : new coff defines
8442 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)

8456 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8457 Motorola and MIT syntax; gas can now assemble either type of

8539 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8540 written with indirection on the last two operands, which can be
8541 either data or address registers. Added a new operand type 'r'
8542 which accepts either register type. Added '(' to notend stuff in
8543 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8882 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8884 * expr.c: If an expression is single comma, then return with
8885 SEG_ABSENT rather than an error - since the sparc front end does
8886 really strange things with things like fbge,a
8888 * as.h: include bfd.h if using many sections
8889 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8890 local labels didn't work.

8898 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8900 * app.c: MRI compatibility - allow single quote to start a string.

8902 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8903 * expr.c: Much rewriting, to accomodate MRI syntax for
8904 expressions. Also easier to read now.
8905 * listing.c: Put back defuns
8906 * read.c: modified to accept MRI syntax, put back listing pseudo
8907 ops so that an assembler built with NO_LISTING ignores list ops
8909 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8910 machine is a SPARC or a 29K.
8911 * config/obj-aout.c: added s_sect pseudo op
8912 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8913 fill in the timestamp.
8914 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8915 anymore, define all the relocs which the tc-<x> bit will use so we
8916 can translate from them to the coff types.
8917 * config/tc-a29k.c: reloc_type isn't ane enum any more
8918 * config/tc-m68k.c: Added NO_RELOC definition.
8920 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)

8933 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8935 * symbols.c (local_label_name): symbols now start with ^A.
8937 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8938 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8939 generate these sections. .align: will use NOP_OPCODE or 0
8940 for padding. This is just for being nice to the
8943 * expr.c (operand): changed to generate local label "\001L0"
8944 starting with a ^A so that it is recognized as a local label.
8946 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8948 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8949 i/o opcodes - inb, inw, outb and outw. string manipulation with
8950 att syntax - scmp, slod, smov, ssca, ssto.
8952 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8953 to just after .file .
8955 In obj_crawl_symbol_chain() where it tries to put the external
8956 symbols apart, with the condition:
8957 (!S_IS_DEFINED(symbolP) &&
8958 !S_IS_DEBUG(symbolP) &&
8959 !SF_GET_STATICS(symbolP))
8960 it was moving too many symbols out. So I switch it back to the
8962 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8964 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8965 so that we don't use the F_RELFLG which make the linker complain
8966 that somebody has stripped the relocation info.
8968 Also, the AIX ld program require that the relocation table
8969 is sorted by r_vaddr like the standard ATT assembler does.
8971 [he also changed the sizeof(struct ...)'s into the coff
8972 style FOOSZ macros. I'm not sure this is right, but I can't
8973 remember why. xoxorich.]

8977 * Makefile.in, configure.in, doc: use the doc. Build it, install
8980 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8982 * read.c: white space and comments only.
8984 * configure.in: use the new atof-ns32.c for ns32k.
8986 * write.c: comment change only.
8988 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8989 aren't yet integrated.
8991 * tc-i860.[hc]: blew off the dust. Something must still be done
8992 about conflicting relocation types.
8994 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8997 * tc-i960.c, tc-sparc.c: white space and comments only.
8999 * tc-a29k.h: delete duplicate macro definition.
9001 * new file atof-ns32k.c copied from hack's last unreleased gas.
9003 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9005 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9008 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9009 ChangeLog's prior to this are sketchy at best. I have logs.
9010 They just aren't ChangeLogs.
