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

536 * Makefile.in (gasp.o): Depends upon config.h.
538 * config/tc-mips.c: Include subsegs.h.
539 (md_apply_fix): If an unconditional b or bal overflows, and we are
540 not assembling PIC code, replace it with a j or jal.
542 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
543 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
545 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
547 * write.c (write_relocs): Add file name and line number to
548 as_fatal calls. Handle bfd_reloc_overflow case specifically when
549 RELOC_EXPANSION_POSSIBLE.
551 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
553 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
554 here. Use them for deciding which PRINTF*LIKE macro definitions
556 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
557 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
558 default definitions matching what we were doing before.
559 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
560 always use the varargs form if not using stdarg. It's safe to
561 always use vfprintf, because libiberty will provide it if the
562 native system doesn't. Also, always make format be const.
563 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
565 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

569 (macro): Hack the -mips3 overflow tests to not fail when offsetT
572 * symbols.h (copy_symbol_attributes): Declare.
574 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

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

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

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

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

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

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

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

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

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

904 st_StaticProc symbol unless it is also a local symbol.
906 * read.c (read_a_source_file): The second argument to as_where is
907 unsigned int *, not int *.
909 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)

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

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

1807 (control_regs): New pointer.
1808 (m68k_ip): Use control_regs instead of testing CPU every time.

2382 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2383 the type of symbol set symbols which happen to be in the absolute
2384 or undefined section.
2386 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2388 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2389 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2390 and -many (all architectures).
2392 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2401 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2403 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2404 branch with an instruction that uses $at, in case the branch is
2406 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2407 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2408 to make it pcrel_offset.
2409 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2410 reloc->address; another gruesome hack to get gas reloc handling to
2413 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2415 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2418 (emit_insn): New function.
2419 (md_assemble): Call it.
2420 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2422 (lituse_pending): New variable. Set by anything that generates a
2423 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2424 tested by code that might want to emit a LITUSE reloc.
2425 (emit_unaligned_io): New function. Currently calls md_assemble,
2426 but it should eventually be converted to generate the insn itself
2427 and call emit_insn directly.
2428 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2429 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2430 emit_bis_r): Likewise.

2434 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2435 unaligned memory access macros.
2436 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2437 the value can't be resolved.
2439 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2441 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2442 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2443 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2445 (mips_force_relocation): New function.
2446 (md_apply_fix): Set fixP->fx_done appropriately.
2447 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2455 * config/tc-mips.c (enum mips_pic_level): New enum.
2456 (mips_pic): Change from int to enum mips_pic_level. Change all
2457 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2458 (load_address): Handle EMBEDDED_PIC.
2459 (macro): Handle EMBEDDED_PIC in all PIC cases.
2460 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2461 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2462 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2463 works). Do not permit -G with SVR4_PIC.
2464 (s_abicalls): Warn if -G was used, and force -G 0.
2465 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2466 anything but a.out, not just for ELF. For ECOFF, don't generate a
2467 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2469 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2471 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2473 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2474 parameters to avoid losing when compiling with HP CC.
2475 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2477 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2479 * Makefile.in (config-stamp): If `defs' is defined, emit a
2480 preprocessor directive to create a macro named by this value into
2481 config.new; don't explicitly go for BFD_ASSEMBLER.
2482 * configure.in: Define `defs', not `BFDDEF'. Set it to
2483 MANY_SEGMENTS for any obj-coffbfd target.
2484 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2485 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2487 (LOCAL_LOADLIBES): Deleted.
2488 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2489 * config/m88kcoff.mt (TDEFINES): Ditto.
2490 * config/ebmon29k.mt: Deleted.

2493 * config/sparc.mt: Deleted.
2494 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2515 bfd_set_symtab is called.
2516 (dump_section_relocs): Note whether a symbol is a section symbol
2518 (adjust_reloc_syms): For now, always supply an absolute symbol for
2519 fixups without symbols but not yet `done'. Use section_symbol to
2520 get the symbol, instead of going directly for abs_symbol.
2521 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2522 reloc is not a section symbol and is not in the symbol table.
2523 (set_symtab): New function, broken out from write_object_file.
2524 Counts symbol table instead of relying on an earlier count.
2525 (write_object_file): Call set_symtab, but do it after potentially
2526 invoking the *_frob_file macros. Don't bother counting symbols.
2527 Call symbol_remove, instead of expanding it in place. Moved the
2528 conditionalized `object_file_size' declaration down to
2529 conditionalized block where it's used. When using the absolute
2530 symbol for a fixup without a symbol, set sy_used_in_reloc.
2531 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2532 the correct symbol for the absolute section.
2534 * subsegs.c (section_symbol): Use symbol_new instead of
2535 symbol_make, since we may want it to go into the symbol table.
2536 Make the new symbol have internal linkage. If
2537 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2538 symbol with the newly created GAS symbol.
2539 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2540 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2545 (in_signed_range): New function.
2547 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2548 (sparc_ip, label "immediate"): Reject constants for pcrel
2549 instructions only if the relocation type indicates a "call"
2550 instruction and the offset is within range of a "jmpl %g0". If
2551 it's not in range, use the absolute section symbol plus an offset.
2552 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2554 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2556 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2559 * configure.in: Eliminated all targets using obj-coff but not
2560 defining BFD_ASSEMBLER; I think all such targets that are
2561 supported will be matched by real CPU-OS combinations earlier in
2563 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2564 some comments about the dpx2 configuration, but left it disabled,
2565 since it couldn't be reached before.
2566 (target a29k-amd-ebmonold): Deleted.
2568 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2576 the 'j' operand if there are no further alternatives for this
2579 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2580 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2581 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2583 * config/tc-mips.c (mips_align): Take new argument, label, and use
2584 it instead of global insn_label.
2585 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2586 call to mips_emit_delay and pass it to mips_align.
2588 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2590 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2592 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2593 argument to a .callinfo directive. Don't loop forever on errors.
2595 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2596 use pre-defined registers as arguments.

2601 S_IS_EXTERNAL when deciding whether to discard a symbol.
2603 * config-gas.com: Scan Makefile.in, not version.c, for current
2604 version number. Delete all versions of temp files when finished
2605 with them. Create config.h.
2607 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2608 values to reduce number of lookups with S_GET_VALUE. Skip debug
2609 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2610 holger@botbso.rhein-main.de.)
2611 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2612 field. (Also from Holger Teutsch.) Watch for a would-be register
2613 mask that spans frags.
2615 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2616 this_base, not line_base. (Patch from Andreas Arens,
2617 ari@obelix.av.rwth-aachen.de.)
2619 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2620 look local if they're exported or undefined. Used to be done for
2623 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2624 Get it from the looked-up symbol, instead of using the string from
2625 the input stream, which is no longer null-terminated.
2626 (LEX_PCT): New macro, defaults to 0.
2627 (lex_type): Use it for `%'.
2629 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2630 (vip_op): Now static, and returns void. Callers changed. Added
2632 (vip): Ditto. Call as_fatal directly if a program bug is

2679 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2680 0xffff for 'j' to be compatible with MIPS assembler. These

4754 default is to assume production environment, and reject configs
4755 still being worked on. Mark Elf configurations (except sparc and
4756 i386) as developmental. Deleted cases matching some generic names
4757 in favor of more specific names. (E.g., when we get Alpha

4783 into a few places. Make all functions and variables which
4784 are only used within tc-hppa.c static. PARAMize all functions.
4785 Add comments to functions. Delete unused functions, variables,
4786 #defines, etc. Delete unused members within structures. Delete
4787 ldil;ble hacks -- it is believed they were installed to work
4788 around old gas bugs. Avoid using mixed case for local
4789 functions, variables, and structures. Fix formatting problems
4790 not found by GNU-indent. Add FIXME notices for things which
4791 should be worked on the near future. Delete lots of old
4792 useless (1.36 PA-SOM) code.

4809 * config/tc-hppa.c: Likewise.
4811 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4812 of elf32_symbol_type.
4813 (pa_export_args): Likewise.

4821 a multiple of the section alignment rather than always a
4824 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4825 bits are zero (eg they specify no relocations), then do not even
4826 bother adding their entries to thesymextn section.

4871 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4873 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4874 ELF, since the ELF object format does not have these type of
4875 relocations. Change the abort into as as_bad and return
4876 BFD_RELOC_NONE to silence compiler warnings.
4877 (md_assemble): Keep track of the instruction size. Allow white

7284 source directory, if that's not the current directory.
7286 * configure.in (per-host): Accept MIPS host with BSD version

7312 avoid some redefinition complaints on some systems.

7315 (seg_name): Use CONST, not const.

7323 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7325 to see a segment offset here.

7330 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7332 * Makefile.in: add dvi target; as-$(config).texinfo might live in

7363 dropping a space immediately following an identifier.

7365 lines; I don't think that can be done portably.
7366 * config/tc-mips.c (macro): Use $AT if target register is zero in

7493 * read.c (s_ignore): Don't declare is_end_of_line. It's
7494 redundant, and triggers a VMS gcc compiler bug.
7496 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7497 current segment as an argument. (Ignored in all cases but VMS.)
7498 All callers and definitions changed.
7500 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)

7505 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
7507 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
7508 so "~0x80" won't be rejected.
7510 * config/obj-elf.c: No longer include elf/reloc.h.
7511 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
7512 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
7514 (obj_elf_xstab): New routine.
7515 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
7516 argument to s_ignore. Put "#if 0" around unused code.
7517 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7518 Call elf_xstabs for .stabs and .xstabs operators.
7520 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7522 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7525 * configure.in: mips-bsd configuration was missing format spec.
7528 * Makefile.in (Makefile): Depends on configure.in.
7530 * config/tc-mips.c (append_insn): Don't check for alignment of
7531 frag in memory; alignment of instructions in section is a separate

7551 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7552 constants are accepted, but symbolic values are not. GCC will not
7553 generate the latter currently.
7555 * frags.c (frag_init): New function.
7556 (zero_address_frag, bss_address_frag): Now initialized at run
7558 * as.c (main): Call frag_init.

7634 new section/subsection.
7636 * read.c: Don't include ctype.h.

7832 For now, only accept "no", until the merge is done.
7834 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7835 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7841 * expr.c: Add "const" modifier to hex_value.
7842 * symbols.c: Finish conversion to S_* macros in the VMS only

7844 md_[long,short]_jump_size. Remove declaration of const_flag
7845 (which will be declared in obj-vms.h).
7846 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7847 Fix arguments to VMS_write_object_file.
7848 * config-gas.com: New file. Script for VMS systems to set up the

7908 mapping to segT enum values.
7909 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7910 if these are used or defined, if BFD_ASSEMBLER.
7911 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7912 subseg_new split into two functions.
7913 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7915 * as.h (volatile): Don't define if already defined.
7916 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7952 (do_relocs_for): Base section address on s_paddr rather than
7953 computing it. Adjust a29k R_IHIHALF special case to account for
7954 section paddr (used to require paddr to be zero). If there are no
7955 reclos, set s_relptr to 0. Set relocation size in object_headers.
7956 (fill_section): Always set s_vaddr here, removing
7957 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7958 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7959 Set STYP_INFO for .comment.
7960 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7961 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
7962 (crawl_symbols): Handle 8 character section name correctly. Use
7963 H_{SET,GET}_* macros.
7964 (do_linenos_for): Set lineno size in object_headers.
7965 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7966 set s_vaddr here. If string_byte_count remains 4, set it back to
7967 0, and only write strings out if there are some. Call
7968 fill_section before do_relocs_for and do_linenos_for.
7969 (obj_coff_section): Handle optional quoted second argument giving
7970 section characteristics.
7971 (obj_coff_bss): Added to handle .bss.
7972 (obj_coff_ident): Added to handle .ident (puts string in .comment
7974 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7975 (fixup_mdeps): Change to segment. Call frag_wane after
7977 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7978 adjustment (already happened only for common symbols, but this is
7980 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7992 (do_scrub_next_char): For \", return " not '.
7993 (symbol_chars): Now const.
7995 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7996 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7998 * config/obj-coff.h: Don't use #elif.
8000 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8001 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8028 using ZERO_BASED_SEGMENTS.
8029 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8030 never set segment address for SEG_E2 (.bss) and don't write out
8031 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8032 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8033 definitions, and don't merge tags with non-tags. Check for .bf
8034 rather than just checking whether the second character is b and
8035 the third character is f.
8036 (obj_coff_val): gcc can generate values which we don't handle
8037 correctly; discard information for now, since it only affects the
8038 debugging information.
8039 (tag_find_or_name): Don't insert tags in the symbol table.
8040 (yank_symbols): Don't merge labels.
8041 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8187 could be doing emulation.
8189 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8192 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8223 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8224 constant will not fit in an immediate field.
8225 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8262 * Support for i386-sysv.
8263 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8287 * tc-m68k.c (get_num): make it work for all segments, not just the
8290 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8292 * configure.in: recognize i386-*-bsd emulation.

8301 * tc-z8k.c: lots of bug fixes
8303 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8305 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8306 #elif, since it is not supported by old compilers.
8307 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8308 couple of expressions in tc-m68k.c.
8310 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8312 * read.c (cons): If NO_RELOC is defined, use it.

8316 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8318 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8319 local labels to start with a .) and set REGISTER_PREFIX to %.
8320 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8322 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8333 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8336 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8338 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8339 sections starting from zero, rather than making them consecutive.
8340 This makes subsequent reloc calculations easier, esp if the object
8341 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8342 allocate lcomm in .data rather than in .bss. It seems that some
8343 tools can't cope with a non-zero sized bss before linkage.
8345 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8347 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8348 throughout. That enum no longer means what we thought it meant.

8351 "-mno-688[58]1" options.
8353 * tc-m68k.c: Added CPU32 support.

8364 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8366 * Makefile.in (install): if $(tooldir) exists, install as in
8369 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8371 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8372 .word is < -32768 or > 32767. The -J flag causes the error to be
8373 ignored. This is to catch over-sized switches generated by gcc on
8374 systems which don't support the broken .word hack.
8375 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8376 write.c (fixup_segment): check for signed .word overflow if
8377 WARN_SIGNED_OVERFLOW_WORD.
8379 * write.c (fixup_segment): fixed missing parens in expression
8380 checking for byte or word overflow.
8382 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

8394 * tc-i386.h : new coff defines
8396 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8398 * input-scrub.c (input_scrub_push): call input_file_begin, not
8400 messages.c (as_perror): print ": " between the passed in error and
8401 the strerror, like perror does.
8403 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8405 * Makefile.in: use gas_target instead of modifying target_cpu.
8406 From Steve Chamberlain:
8407 Makefile.in: Handle m68*-*-coff*.
8408 read.c, read.h: add mult argument to s_space
8410 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8411 Motorola and MIT syntax; gas can now assemble either type of
8413 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
8414 From Steve Chamberlain:
8415 m68kcoff.mt: for m68k COFF.
8416 obj-coffbfd.c: (fixup_mdeps) added
8417 (size_section) removed bad sanity check
8418 (fill_section) added rs_machine_dependent case
8419 (write_object_file) call fixup_mdeps
8420 (fixup_segment) set fx_subsy to 0.
8421 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8423 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8426 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8428 * Makefile.in (LIBS): Include opcode library.
8430 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
8432 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
8433 including zero are accepted, pass +0.0.

8437 * Makefile.in: map "as" through program_transform_name when
8440 * doc/Makefile.in: map "as" through program_transform_name when

8455 * config/tc-m68k.c (init_table): Now const. Always include 68851
8456 data, so that "bc" is available to 68040 cache instructions.
8457 Added "tt0", "tt1", and 68ec030 variants.
8458 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8459 (enum _register): Added TT0, TT1.

8491 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8493 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8494 written with indirection on the last two operands, which can be
8495 either data or address registers. Added a new operand type 'r'
8496 which accepts either register type. Added '(' to notend stuff in
8497 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8544 being used with args swapped, causing occasional lossage when
8545 refilling buffers after an include file.

8609 characteristics have been), default to 68020. Don't need extra
8610 quotes around error string.

8746 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8748 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8749 where gcc looks for it.

8833 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8834 copyrights to '92, changed some from Cygnus to FSF.
8836 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8838 * expr.c: If an expression is single comma, then return with
8839 SEG_ABSENT rather than an error - since the sparc front end does
8840 really strange things with things like fbge,a
8842 * as.h: include bfd.h if using many sections
8843 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8844 local labels didn't work.
8845 * listing.c (list_symbol_table): don't core dump when there's no
8847 * write.c, write.h: call fix_new with the right number of args on
8849 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8852 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8854 * app.c: MRI compatibility - allow single quote to start a string.
8855 * as.c: fix typo recently introduced.
8856 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8857 * expr.c: Much rewriting, to accomodate MRI syntax for
8858 expressions. Also easier to read now.
8859 * listing.c: Put back defuns
8860 * read.c: modified to accept MRI syntax, put back listing pseudo
8861 ops so that an assembler built with NO_LISTING ignores list ops
8863 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8864 machine is a SPARC or a 29K.
8865 * config/obj-aout.c: added s_sect pseudo op
8866 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8867 fill in the timestamp.
8868 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8869 anymore, define all the relocs which the tc-<x> bit will use so we
8870 can translate from them to the coff types.
8871 * config/tc-a29k.c: reloc_type isn't ane enum any more
8872 * config/tc-m68k.c: Added NO_RELOC definition.
8874 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8876 * Makefile.in: put header files before C source for TAGS; remove
8877 references to non-existent syscalls.h.
8879 * read.c, write.c subsegs.c: back out the .bss changes.
8881 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8883 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8887 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8889 * symbols.c (local_label_name): symbols now start with ^A.
8891 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8892 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8893 generate these sections. .align: will use NOP_OPCODE or 0
8894 for padding. This is just for being nice to the
8897 * expr.c (operand): changed to generate local label "\001L0"
8898 starting with a ^A so that it is recognized as a local label.
8900 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8902 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8903 i/o opcodes - inb, inw, outb and outw. string manipulation with
8904 att syntax - scmp, slod, smov, ssca, ssto.
8906 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8907 to just after .file .
8909 In obj_crawl_symbol_chain() where it tries to put the external
8910 symbols apart, with the condition:
8911 (!S_IS_DEFINED(symbolP) &&
8912 !S_IS_DEBUG(symbolP) &&
8913 !SF_GET_STATICS(symbolP))
8914 it was moving too many symbols out. So I switch it back to the
8916 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8918 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8919 so that we don't use the F_RELFLG which make the linker complain
8920 that somebody has stripped the relocation info.
8922 Also, the AIX ld program require that the relocation table
8923 is sorted by r_vaddr like the standard ATT assembler does.
8925 [he also changed the sizeof(struct ...)'s into the coff
8926 style FOOSZ macros. I'm not sure this is right, but I can't
8927 remember why. xoxorich.]
8929 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
