511 constant-valued symbol, convert to O_symbol and re-reduce.
512 (S_GET_VALUE): If symbol needs resolving, resolve it.
513 (indent_level): No longer static.
514 (print_symbol_value_1): Don't print frag address if it matches
515 zero_address_frag. Don't print "resolving" if already resolved.
516 Print segment name. Don't call print_expr_1 on an undefined
518 (print_expr_1): Fix whitespace before printing X_add_number.
520 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
521 not symbol_new, for symbols holding expression values.
522 * expr.h (make_expr_symbol): Move declaration here.
523 * write.c (fix_new_exp): Handle O_add by creating an
524 expression-valued symbol, and calling fix_new_exp recursively.
525 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
526 undefined symbol and a constant, fold the constant into the fixup,
527 and refer to the undefined symbol directly. Then process the
528 fixup again from scratch.
529 (write_object_file): Before calling adjust_reloc_syms, make a pass
530 through the symbol list trying to resolve values.
532 * write.c (print_fixup): New routine, for debugging.
533 (write_relocs): Call bfd_install_relocation. Deleted various
534 hacks for working around problems with bfd_perform_relocation.

540 * Makefile.in (gasp.o): Depends upon config.h.
542 * config/tc-mips.c: Include subsegs.h.
543 (md_apply_fix): If an unconditional b or bal overflows, and we are
544 not assembling PIC code, replace it with a j or jal.
546 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
547 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
549 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
551 * write.c (write_relocs): Add file name and line number to
552 as_fatal calls. Handle bfd_reloc_overflow case specifically when
553 RELOC_EXPANSION_POSSIBLE.
555 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
557 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
558 here. Use them for deciding which PRINTF*LIKE macro definitions
560 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
561 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
562 default definitions matching what we were doing before.
563 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
564 always use the varargs form if not using stdarg. It's safe to
565 always use vfprintf, because libiberty will provide it if the
566 native system doesn't. Also, always make format be const.
567 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
569 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
571 * config/tc-mips.c (load_register): Always use addiu when adding a
572 constant to $zero--no need to use daddiu.
573 (macro): Hack the -mips3 overflow tests to not fail when offsetT
576 * symbols.h (copy_symbol_attributes): Declare.
578 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
580 * listing.c: Bugfixes based in part on patches from Paul
582 (listing_newline): Check filename as well as line number when
583 deciding whether to record it.
584 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
585 false (if defined) as well as checking for reg_section.
586 (listing_listing): Iterate fetching lines while line number is too
587 low, and we haven't run off the end of the input file.
589 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
591 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

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

607 X_add_number is zero.
608 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
610 * config/tc-i960.c: Lots of whitespace, comment reformatting,
612 (strchr): Don't declare.

614 md_estimate_size_before_relax, md_ri_to_chars,
615 md_create_short_jump, md_create_long_jump.
616 (brtab_emit): Use data_section, not SEG_DATA.
618 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
620 * config/vms-conf.h: new file, manually derived from conf.in.
621 * config-gas.com: use it, and eliminate obsolete "host.h".
623 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
625 * config/tc-ppc.c (ppc_current_block): New static variable.
626 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

630 (ppc_es): Clear ppc_current_block.
631 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
632 from the csect of the enclosing block.
634 * config/tc-mips.c (insns_since_cache_access): Remove.
635 (append_insn): Remove setting of insns_since_cache_access, and
636 special 4600 handling; it turns out not to be required.
638 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
640 * config/tc-mips.c (md_shortopts): Remove E.
641 (md_longopts): Add EB and EL.
642 (md_parse_option): Handle -EB and -EL as separate options, rather
643 than as a single -E option with an argument.
645 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
647 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
648 involving global symbols too.
650 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
652 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
654 * configure.in: Test for remove, not delete. Fix cross-assembler
656 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
659 * read.c (pseudo_set, case O_symbol): If
660 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
661 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

664 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
666 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
667 many others): new macros; values obtained from "DSTRECRDS.SDL".
668 * config/obj-vms.h (various): use them.
669 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
670 representation (only enum bitfields can avoid being bitstrings).
671 (bitfield_suffix, setup_basic_type): new routines.
672 (VMS_typedef_parse): use them. Now recognize bitfields of all
673 integral types, not just type `int'. Caveat: the representation
674 used for bitfields still does not work for objects placed in
675 registers, and gcc's optimizer sometimes puts small structs there.
677 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
679 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
681 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
682 (tc_frob_label): define this to call vms_check_for_special_label,
683 and declare the latter.
684 * config/obj-vms.c (vax_g_doubles): declare this file-scope
686 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
687 (vms_check_for_special_label): new routine (tc_frob_label).
688 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
689 and `gcc2_compiled.' labels; they won't reach here any more.
690 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
691 double', use `vax_g_doubles' flag to select type of double.
692 (VMS_write_object_file) [traceback setup]: don't pass symbols
693 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
694 and TBT_Routine_End functions.
696 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
698 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
699 S_GET_VALUE() to avoid many repeated function calls.
700 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
701 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
702 gets requested. [All the HACK_DEC_C_STARTUP code appears to
703 be obsolete; gcc does it automatically for vms target. It's
704 also misnamed, because it is for the "VAX C" run-time library,
705 not the newer "DEC C" one which has much different startup code.]
706 {various}: use `S_SET_xxx(symbol,new_value)' rather than
707 `S_GET_xxx(symbol) = new_value'.
709 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
711 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

716 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
718 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
720 * expr.c (expr): Don't reduce the difference of two symbols in the
721 same frag if the symbols are not in normal sections.
723 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
724 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
725 (obj_attach_unwind_info): Do not define. Not needed anymore.
726 * config/tc-hppa.c: Delete whitespace at EOL.
727 (struct hppa_fix_struct): Delete fx_unwind field and all references.
728 (fix_new_hppa): Last arg is now a pointer to an int. Do not
729 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
730 fixups, store 32bits of unwind information in the fx_addnumber
732 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
733 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
734 pointer to 32 bits of unwind info.
735 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
736 pointer to the dummy symbol; set the addend field to fx_addnumber.
737 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
738 rather than &bfd_XXX_section.
740 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
742 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
743 value by one; discard adjustments previously being made. From
746 VMS- and Vax-related changes from Pat Rankin:
747 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
748 * vmsconf.sh: no longer have make-gas.com echo text about needing
749 to modify the gcc-vms driver when intending to use with gcc 1.x.
750 * as.c (parse_options): suppress 'v' from std_short_options and
751 eliminate VMS-specific conditional initialization;
752 [default case]: check for '-v' if md_parse_options doesn't recognize
754 [default case, #if VMS]: check for filename argument when '-v' seen;
756 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
757 for O_big literal operands (double floats and long long ints);
758 [VMS, md_shortopts]: add second colon after 'v';
759 (md_parse_options) [VMS, case 'v']: check for argument, so
760 caller can handle `-v' w/o arg.

811 Update for autoconf 1.118:
812 * gdbinit.in: New file, created from old .gdbinit.
814 * aclocal.m4 (GAS_GDBINIT): Deleted.
815 * configure.in: Don't use it. Instead, generate .gdbinit from
816 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
817 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
818 to ensure that older versions of autoconf aren't used.
819 * Makefile.in: Added @configure_input@ line.

873 disp_reloc field to reloc() function, and use TC_RELOC to generate
874 value to pass to fix_new_exp.
875 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
877 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

908 st_StaticProc symbol unless it is also a local symbol.
910 * read.c (read_a_source_file): The second argument to as_where is
911 unsigned int *, not int *.
913 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)
915 * config/obj-ecoff.h : Change names to OBJ_GENERATE_ASM_LINENO,
916 and generate_asm_lineno.

951 * Makefile.in (CC_FOR_TARGET, NM_FOR_TARGET, OBJDUMP_FOR_TARGET,
952 install, uninstall): Don't use "brokensed" hack any more, the new

958 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
959 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
960 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
961 message to try to ease confusion about autoconf's
962 "cross-compiling" message.
963 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
964 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

1811 (control_regs): New pointer.
1812 (m68k_ip): Use control_regs instead of testing CPU every time.

1900 allocating new symbol entry and linking it to VMS_Symbol_type_list.
1902 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
1904 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

2376 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2377 cross section PC relative relocs right for COFF and ELF.
2379 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2387 the type of symbol set symbols which happen to be in the absolute
2388 or undefined section.

2392 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2393 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2394 and -many (all architectures).

2405 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2407 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2408 branch with an instruction that uses $at, in case the branch is
2410 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

2412 to make it pcrel_offset.
2413 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2414 reloc->address; another gruesome hack to get gas reloc handling to
2417 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2419 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2422 (emit_insn): New function.
2423 (md_assemble): Call it.
2424 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2426 (lituse_pending): New variable. Set by anything that generates a
2427 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2428 tested by code that might want to emit a LITUSE reloc.
2429 (emit_unaligned_io): New function. Currently calls md_assemble,
2430 but it should eventually be converted to generate the insn itself
2431 and call emit_insn directly.
2432 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2433 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2434 emit_bis_r): Likewise.

2443 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2445 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2446 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2447 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2449 (mips_force_relocation): New function.
2450 (md_apply_fix): Set fixP->fx_done appropriately.
2451 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2459 * config/tc-mips.c (enum mips_pic_level): New enum.
2460 (mips_pic): Change from int to enum mips_pic_level. Change all

2462 (load_address): Handle EMBEDDED_PIC.
2463 (macro): Handle EMBEDDED_PIC in all PIC cases.
2464 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2465 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2466 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2467 works). Do not permit -G with SVR4_PIC.
2468 (s_abicalls): Warn if -G was used, and force -G 0.
2469 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2470 anything but a.out, not just for ELF. For ECOFF, don't generate a
2471 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2473 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2475 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2477 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2478 parameters to avoid losing when compiling with HP CC.
2479 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2481 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2483 * Makefile.in (config-stamp): If `defs' is defined, emit a
2484 preprocessor directive to create a macro named by this value into
2485 config.new; don't explicitly go for BFD_ASSEMBLER.
2486 * configure.in: Define `defs', not `BFDDEF'. Set it to
2487 MANY_SEGMENTS for any obj-coffbfd target.
2488 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2489 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2491 (LOCAL_LOADLIBES): Deleted.
2492 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2493 * config/m88kcoff.mt (TDEFINES): Ditto.

2519 bfd_set_symtab is called.
2520 (dump_section_relocs): Note whether a symbol is a section symbol
2522 (adjust_reloc_syms): For now, always supply an absolute symbol for
2523 fixups without symbols but not yet `done'. Use section_symbol to
2524 get the symbol, instead of going directly for abs_symbol.
2525 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2526 reloc is not a section symbol and is not in the symbol table.
2527 (set_symtab): New function, broken out from write_object_file.
2528 Counts symbol table instead of relying on an earlier count.
2529 (write_object_file): Call set_symtab, but do it after potentially
2530 invoking the *_frob_file macros. Don't bother counting symbols.
2531 Call symbol_remove, instead of expanding it in place. Moved the
2532 conditionalized `object_file_size' declaration down to
2533 conditionalized block where it's used. When using the absolute
2534 symbol for a fixup without a symbol, set sy_used_in_reloc.
2535 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2536 the correct symbol for the absolute section.
2538 * subsegs.c (section_symbol): Use symbol_new instead of
2539 symbol_make, since we may want it to go into the symbol table.
2540 Make the new symbol have internal linkage. If
2541 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2542 symbol with the newly created GAS symbol.
2543 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2544 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2551 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2552 (sparc_ip, label "immediate"): Reject constants for pcrel
2553 instructions only if the relocation type indicates a "call"
2554 instruction and the offset is within range of a "jmpl %g0". If
2555 it's not in range, use the absolute section symbol plus an offset.
2556 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2558 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2560 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2563 * configure.in: Eliminated all targets using obj-coff but not
2564 defining BFD_ASSEMBLER; I think all such targets that are
2565 supported will be matched by real CPU-OS combinations earlier in
2567 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2568 some comments about the dpx2 configuration, but left it disabled,
2569 since it couldn't be reached before.
2570 (target a29k-amd-ebmonold): Deleted.
2572 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2580 the 'j' operand if there are no further alternatives for this
2583 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2584 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2585 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2587 * config/tc-mips.c (mips_align): Take new argument, label, and use
2588 it instead of global insn_label.
2589 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2590 call to mips_emit_delay and pass it to mips_align.
2592 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2594 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2596 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2597 argument to a .callinfo directive. Don't loop forever on errors.
2599 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2600 use pre-defined registers as arguments.

2605 S_IS_EXTERNAL when deciding whether to discard a symbol.
2607 * config-gas.com: Scan Makefile.in, not version.c, for current
2608 version number. Delete all versions of temp files when finished
2609 with them. Create config.h.
2611 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2612 values to reduce number of lookups with S_GET_VALUE. Skip debug
2613 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2614 holger@botbso.rhein-main.de.)
2615 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2616 field. (Also from Holger Teutsch.) Watch for a would-be register
2617 mask that spans frags.
2619 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2620 this_base, not line_base. (Patch from Andreas Arens,
2621 ari@obelix.av.rwth-aachen.de.)
2623 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2624 look local if they're exported or undefined. Used to be done for
2627 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2628 Get it from the looked-up symbol, instead of using the string from
2629 the input stream, which is no longer null-terminated.
2630 (LEX_PCT): New macro, defaults to 0.
2631 (lex_type): Use it for `%'.
2633 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2683 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2684 0xffff for 'j' to be compatible with MIPS assembler. These

4758 default is to assume production environment, and reject configs
4759 still being worked on. Mark Elf configurations (except sparc and
4760 i386) as developmental. Deleted cases matching some generic names
4761 in favor of more specific names. (E.g., when we get Alpha

4787 into a few places. Make all functions and variables which
4788 are only used within tc-hppa.c static. PARAMize all functions.
4789 Add comments to functions. Delete unused functions, variables,
4790 #defines, etc. Delete unused members within structures. Delete
4791 ldil;ble hacks -- it is believed they were installed to work
4792 around old gas bugs. Avoid using mixed case for local
4793 functions, variables, and structures. Fix formatting problems
4794 not found by GNU-indent. Add FIXME notices for things which
4795 should be worked on the near future. Delete lots of old
4796 useless (1.36 PA-SOM) code.

4815 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4816 of elf32_symbol_type.
4817 (pa_export_args): Likewise.

4825 a multiple of the section alignment rather than always a
4828 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

4875 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4877 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4878 ELF, since the ELF object format does not have these type of
4879 relocations. Change the abort into as as_bad and return
4880 BFD_RELOC_NONE to silence compiler warnings.
4881 (md_assemble): Keep track of the instruction size. Allow white

7316 avoid some redefinition complaints on some systems.

7319 (seg_name): Use CONST, not const.

7327 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7334 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7336 * Makefile.in: add dvi target; as-$(config).texinfo might live in

7367 dropping a space immediately following an identifier.

7369 lines; I don't think that can be done portably.
7370 * config/tc-mips.c (macro): Use $AT if target register is zero in

7492 Wed Mar 3 10:41:46 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7494 Patches from Eric Youngdale:
7495 * make-gas.com: Find obstack.obj if it's not in the current
7497 * read.c (s_ignore): Don't declare is_end_of_line. It's
7498 redundant, and triggers a VMS gcc compiler bug.
7500 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7501 current segment as an argument. (Ignored in all cases but VMS.)
7502 All callers and definitions changed.

7511 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
7512 so "~0x80" won't be rejected.
7514 * config/obj-elf.c: No longer include elf/reloc.h.
7515 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.

7518 (obj_elf_xstab): New routine.
7519 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
7520 argument to s_ignore. Put "#if 0" around unused code.
7521 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7522 Call elf_xstabs for .stabs and .xstabs operators.
7524 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7526 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7529 * configure.in: mips-bsd configuration was missing format spec.
7532 * Makefile.in (Makefile): Depends on configure.in.
7534 * config/tc-mips.c (append_insn): Don't check for alignment of
7535 frag in memory; alignment of instructions in section is a separate

7555 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7556 constants are accepted, but symbolic values are not. GCC will not
7557 generate the latter currently.
7559 * frags.c (frag_init): New function.
7560 (zero_address_frag, bss_address_frag): Now initialized at run
7562 * as.c (main): Call frag_init.

7638 new section/subsection.
7640 * read.c: Don't include ctype.h.

7836 For now, only accept "no", until the merge is done.
7838 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7839 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7845 * expr.c: Add "const" modifier to hex_value.
7846 * symbols.c: Finish conversion to S_* macros in the VMS only
7847 parts of the program. Add "const" modifier to
7848 md_[long,short]_jump_size. Remove declaration of const_flag
7849 (which will be declared in obj-vms.h).
7850 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7851 Fix arguments to VMS_write_object_file.
7852 * config-gas.com: New file. Script for VMS systems to set up the
7853 configuration to build gas for VMS, and create config.status.

7912 mapping to segT enum values.
7913 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7914 if these are used or defined, if BFD_ASSEMBLER.
7915 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7916 subseg_new split into two functions.
7917 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7919 * as.h (volatile): Don't define if already defined.

7955 (size_section): Restored sanity check.
7956 (do_relocs_for): Base section address on s_paddr rather than
7957 computing it. Adjust a29k R_IHIHALF special case to account for
7958 section paddr (used to require paddr to be zero). If there are no
7959 reclos, set s_relptr to 0. Set relocation size in object_headers.
7960 (fill_section): Always set s_vaddr here, removing
7961 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7962 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7963 Set STYP_INFO for .comment.
7964 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7965 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
7966 (crawl_symbols): Handle 8 character section name correctly. Use
7967 H_{SET,GET}_* macros.
7968 (do_linenos_for): Set lineno size in object_headers.
7969 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7970 set s_vaddr here. If string_byte_count remains 4, set it back to
7971 0, and only write strings out if there are some. Call
7972 fill_section before do_relocs_for and do_linenos_for.
7973 (obj_coff_section): Handle optional quoted second argument giving
7974 section characteristics.
7975 (obj_coff_bss): Added to handle .bss.
7976 (obj_coff_ident): Added to handle .ident (puts string in .comment
7978 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7979 (fixup_mdeps): Change to segment. Call frag_wane after
7981 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7982 adjustment (already happened only for common symbols, but this is
7984 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7996 (do_scrub_next_char): For \", return " not '.
7997 (symbol_chars): Now const.
7999 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8000 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8002 * config/obj-coff.h: Don't use #elif.
8004 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8005 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8034 never set segment address for SEG_E2 (.bss) and don't write out
8035 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8036 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8037 definitions, and don't merge tags with non-tags. Check for .bf
8038 rather than just checking whether the second character is b and
8039 the third character is f.
8040 (obj_coff_val): gcc can generate values which we don't handle
8041 correctly; discard information for now, since it only affects the
8042 debugging information.
8043 (tag_find_or_name): Don't insert tags in the symbol table.
8044 (yank_symbols): Don't merge labels.
8045 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8191 could be doing emulation.
8193 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8196 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8227 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8228 constant will not fit in an immediate field.
8229 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8266 * Support for i386-sysv.
8267 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8291 * tc-m68k.c (get_num): make it work for all segments, not just the
8294 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8296 * configure.in: recognize i386-*-bsd emulation.

8305 * tc-z8k.c: lots of bug fixes
8307 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8309 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8310 #elif, since it is not supported by old compilers.
8311 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8312 couple of expressions in tc-m68k.c.
8314 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

8322 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8323 local labels to start with a .) and set REGISTER_PREFIX to %.
8324 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8326 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8337 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8340 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8342 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8343 sections starting from zero, rather than making them consecutive.
8344 This makes subsequent reloc calculations easier, esp if the object
8345 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8346 allocate lcomm in .data rather than in .bss. It seems that some
8347 tools can't cope with a non-zero sized bss before linkage.
8349 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8351 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8352 throughout. That enum no longer means what we thought it meant.

8355 "-mno-688[58]1" options.
8357 * tc-m68k.c: Added CPU32 support.

8368 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8370 * Makefile.in (install): if $(tooldir) exists, install as in
8373 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8375 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8376 .word is < -32768 or > 32767. The -J flag causes the error to be
8377 ignored. This is to catch over-sized switches generated by gcc on
8378 systems which don't support the broken .word hack.
8379 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8380 write.c (fixup_segment): check for signed .word overflow if
8381 WARN_SIGNED_OVERFLOW_WORD.
8383 * write.c (fixup_segment): fixed missing parens in expression
8384 checking for byte or word overflow.
8386 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

8398 * tc-i386.h : new coff defines
8400 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8402 * input-scrub.c (input_scrub_push): call input_file_begin, not
8404 messages.c (as_perror): print ": " between the passed in error and
8405 the strerror, like perror does.
8407 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8409 * Makefile.in: use gas_target instead of modifying target_cpu.
8410 From Steve Chamberlain:
8411 Makefile.in: Handle m68*-*-coff*.
8412 read.c, read.h: add mult argument to s_space
8414 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8415 Motorola and MIT syntax; gas can now assemble either type of
8417 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
8418 From Steve Chamberlain:
8419 m68kcoff.mt: for m68k COFF.
8420 obj-coffbfd.c: (fixup_mdeps) added
8421 (size_section) removed bad sanity check
8422 (fill_section) added rs_machine_dependent case
8423 (write_object_file) call fixup_mdeps
8424 (fixup_segment) set fx_subsy to 0.
8425 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8427 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8430 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8432 * Makefile.in (LIBS): Include opcode library.
8434 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
8436 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
8437 including zero are accepted, pass +0.0.

8457 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8459 * config/tc-m68k.c (init_table): Now const. Always include 68851
8460 data, so that "bc" is available to 68040 cache instructions.
8461 Added "tt0", "tt1", and 68ec030 variants.
8462 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8463 (enum _register): Added TT0, TT1.

8495 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8497 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8498 written with indirection on the last two operands, which can be
8499 either data or address registers. Added a new operand type 'r'
8500 which accepts either register type. Added '(' to notend stuff in
8501 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8548 being used with args swapped, causing occasional lossage when
8549 refilling buffers after an include file.

8611 processor/opcode mismatch, so reword the error message.
8612 (md_assemble): If no CPU has been set (even if FPU/PMMU
8613 characteristics have been), default to 68020. Don't need extra
8614 quotes around error string.

8750 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8752 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8753 where gcc looks for it.

8836 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8837 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8838 copyrights to '92, changed some from Cygnus to FSF.
8840 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8842 * expr.c: If an expression is single comma, then return with
8843 SEG_ABSENT rather than an error - since the sparc front end does
8844 really strange things with things like fbge,a
8846 * as.h: include bfd.h if using many sections
8847 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8848 local labels didn't work.
8849 * listing.c (list_symbol_table): don't core dump when there's no
8851 * write.c, write.h: call fix_new with the right number of args on
8853 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8856 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8858 * app.c: MRI compatibility - allow single quote to start a string.
8859 * as.c: fix typo recently introduced.
8860 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8861 * expr.c: Much rewriting, to accomodate MRI syntax for
8862 expressions. Also easier to read now.
8863 * listing.c: Put back defuns
8864 * read.c: modified to accept MRI syntax, put back listing pseudo
8865 ops so that an assembler built with NO_LISTING ignores list ops
8867 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8868 machine is a SPARC or a 29K.
8869 * config/obj-aout.c: added s_sect pseudo op
8870 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8871 fill in the timestamp.
8872 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8873 anymore, define all the relocs which the tc-<x> bit will use so we
8874 can translate from them to the coff types.
8875 * config/tc-a29k.c: reloc_type isn't ane enum any more
8876 * config/tc-m68k.c: Added NO_RELOC definition.
8878 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8880 * Makefile.in: put header files before C source for TAGS; remove
8881 references to non-existent syscalls.h.
8883 * read.c, write.c subsegs.c: back out the .bss changes.
8885 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8887 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8891 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8893 * symbols.c (local_label_name): symbols now start with ^A.
8895 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8896 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8897 generate these sections. .align: will use NOP_OPCODE or 0
8898 for padding. This is just for being nice to the
8901 * expr.c (operand): changed to generate local label "\001L0"
8902 starting with a ^A so that it is recognized as a local label.
8904 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8906 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8907 i/o opcodes - inb, inw, outb and outw. string manipulation with
8908 att syntax - scmp, slod, smov, ssca, ssto.
8910 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8911 to just after .file .
8913 In obj_crawl_symbol_chain() where it tries to put the external
8914 symbols apart, with the condition:
8915 (!S_IS_DEFINED(symbolP) &&
8916 !S_IS_DEBUG(symbolP) &&
8917 !SF_GET_STATICS(symbolP))
8918 it was moving too many symbols out. So I switch it back to the
8920 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8922 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8923 so that we don't use the F_RELFLG which make the linker complain
8924 that somebody has stripped the relocation info.
8926 Also, the AIX ld program require that the relocation table
8927 is sorted by r_vaddr like the standard ATT assembler does.
8929 [he also changed the sizeof(struct ...)'s into the coff
8930 style FOOSZ macros. I'm not sure this is right, but I can't
8931 remember why. xoxorich.]
8933 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8935 * Makefile.in, configure.in, doc: use the doc. Build it, install
8938 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
