504 (write_object_file): Before calling adjust_reloc_syms, make a pass
505 through the symbol list trying to resolve values.
507 * write.c (print_fixup): New routine, for debugging.
508 (write_relocs): Call bfd_install_relocation. Deleted various
509 hacks for working around problems with bfd_perform_relocation.

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

547 constant to $zero--no need to use daddiu.
548 (macro): Hack the -mips3 overflow tests to not fail when offsetT
551 * symbols.h (copy_symbol_attributes): Declare.
553 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
555 * listing.c: Bugfixes based in part on patches from Paul
557 (listing_newline): Check filename as well as line number when
558 deciding whether to record it.
559 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
560 false (if defined) as well as checking for reg_section.
561 (listing_listing): Iterate fetching lines while line number is too
562 low, and we haven't run off the end of the input file.
564 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
566 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

575 * config/ho-*.h: Now-unused files deleted.
577 * symbols.c (copy_symbol_attributes): New function. Copies BFD
578 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
579 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
580 zero. Don't call obj_frob_forward_symbol.

582 X_add_number is zero.
583 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
585 * config/tc-i960.c: Lots of whitespace, comment reformatting,
587 (strchr): Don't declare.

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

605 (ppc_es): Clear ppc_current_block.
606 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
607 from the csect of the enclosing block.
609 * config/tc-mips.c (insns_since_cache_access): Remove.
610 (append_insn): Remove setting of insns_since_cache_access, and
611 special 4600 handling; it turns out not to be required.
613 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
615 * config/tc-mips.c (md_shortopts): Remove E.
616 (md_longopts): Add EB and EL.
617 (md_parse_option): Handle -EB and -EL as separate options, rather
618 than as a single -E option with an argument.
620 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
622 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
623 involving global symbols too.
625 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
627 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
629 * configure.in: Test for remove, not delete. Fix cross-assembler
631 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
634 * read.c (pseudo_set, case O_symbol): If
635 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
636 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
637 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
639 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
641 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
642 many others): new macros; values obtained from "DSTRECRDS.SDL".
643 * config/obj-vms.h (various): use them.
644 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
645 representation (only enum bitfields can avoid being bitstrings).
646 (bitfield_suffix, setup_basic_type): new routines.
647 (VMS_typedef_parse): use them. Now recognize bitfields of all
648 integral types, not just type `int'. Caveat: the representation
649 used for bitfields still does not work for objects placed in
650 registers, and gcc's optimizer sometimes puts small structs there.
652 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
654 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
656 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
657 (tc_frob_label): define this to call vms_check_for_special_label,
658 and declare the latter.
659 * config/obj-vms.c (vax_g_doubles): declare this file-scope
661 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
662 (vms_check_for_special_label): new routine (tc_frob_label).
663 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
664 and `gcc2_compiled.' labels; they won't reach here any more.
665 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
666 double', use `vax_g_doubles' flag to select type of double.
667 (VMS_write_object_file) [traceback setup]: don't pass symbols
668 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
669 and TBT_Routine_End functions.
671 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
673 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
674 S_GET_VALUE() to avoid many repeated function calls.
675 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
676 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
677 gets requested. [All the HACK_DEC_C_STARTUP code appears to
678 be obsolete; gcc does it automatically for vms target. It's
679 also misnamed, because it is for the "VAX C" run-time library,
680 not the newer "DEC C" one which has much different startup code.]
681 {various}: use `S_SET_xxx(symbol,new_value)' rather than
682 `S_GET_xxx(symbol) = new_value'.
684 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
686 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

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

786 Update for autoconf 1.118:
787 * gdbinit.in: New file, created from old .gdbinit.
789 * aclocal.m4 (GAS_GDBINIT): Deleted.
790 * configure.in: Don't use it. Instead, generate .gdbinit from
791 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
792 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
793 to ensure that older versions of autoconf aren't used.
794 * Makefile.in: Added @configure_input@ line.

848 disp_reloc field to reloc() function, and use TC_RELOC to generate
849 value to pass to fix_new_exp.
850 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
852 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

885 * read.c (read_a_source_file): The second argument to as_where is
886 unsigned int *, not int *.
888 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)

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

933 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
934 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
935 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
936 message to try to ease confusion about autoconf's
937 "cross-compiling" message.
938 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
939 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

1786 (control_regs): New pointer.
1787 (m68k_ip): Use control_regs instead of testing CPU every time.

2368 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2369 and -many (all architectures).
2371 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2380 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2382 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2383 branch with an instruction that uses $at, in case the branch is
2385 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2386 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2387 to make it pcrel_offset.
2388 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2389 reloc->address; another gruesome hack to get gas reloc handling to
2392 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2394 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2397 (emit_insn): New function.
2398 (md_assemble): Call it.
2399 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2401 (lituse_pending): New variable. Set by anything that generates a
2402 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2403 tested by code that might want to emit a LITUSE reloc.
2404 (emit_unaligned_io): New function. Currently calls md_assemble,
2405 but it should eventually be converted to generate the insn itself
2406 and call emit_insn directly.
2407 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2408 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2409 emit_bis_r): Likewise.
2410 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2411 (alpha_ip, label get_macro): Don't emit the final instruction if
2413 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2414 unaligned memory access macros.
2415 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2416 the value can't be resolved.
2418 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2420 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2421 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2422 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2424 (mips_force_relocation): New function.
2425 (md_apply_fix): Set fixP->fx_done appropriately.
2426 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2434 * config/tc-mips.c (enum mips_pic_level): New enum.
2435 (mips_pic): Change from int to enum mips_pic_level. Change all
2436 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2437 (load_address): Handle EMBEDDED_PIC.
2438 (macro): Handle EMBEDDED_PIC in all PIC cases.
2439 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2440 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2441 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2442 works). Do not permit -G with SVR4_PIC.
2443 (s_abicalls): Warn if -G was used, and force -G 0.
2444 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2445 anything but a.out, not just for ELF. For ECOFF, don't generate a
2446 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2448 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2450 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2452 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2453 parameters to avoid losing when compiling with HP CC.
2454 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2456 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2458 * Makefile.in (config-stamp): If `defs' is defined, emit a
2459 preprocessor directive to create a macro named by this value into
2460 config.new; don't explicitly go for BFD_ASSEMBLER.
2461 * configure.in: Define `defs', not `BFDDEF'. Set it to
2462 MANY_SEGMENTS for any obj-coffbfd target.
2463 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2464 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2466 (LOCAL_LOADLIBES): Deleted.
2467 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2468 * config/m88kcoff.mt (TDEFINES): Ditto.
2469 * config/ebmon29k.mt: Deleted.
2470 * config/h8300hds.mt: Deleted.
2471 * config/ic960coff.mt: Deleted.
2472 * config/sparc.mt: Deleted.
2473 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2475 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2476 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

2494 bfd_set_symtab is called.
2495 (dump_section_relocs): Note whether a symbol is a section symbol
2497 (adjust_reloc_syms): For now, always supply an absolute symbol for
2498 fixups without symbols but not yet `done'. Use section_symbol to
2499 get the symbol, instead of going directly for abs_symbol.
2500 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2501 reloc is not a section symbol and is not in the symbol table.
2502 (set_symtab): New function, broken out from write_object_file.
2503 Counts symbol table instead of relying on an earlier count.
2504 (write_object_file): Call set_symtab, but do it after potentially
2505 invoking the *_frob_file macros. Don't bother counting symbols.
2506 Call symbol_remove, instead of expanding it in place. Moved the
2507 conditionalized `object_file_size' declaration down to
2508 conditionalized block where it's used. When using the absolute
2509 symbol for a fixup without a symbol, set sy_used_in_reloc.
2510 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2511 the correct symbol for the absolute section.
2513 * subsegs.c (section_symbol): Use symbol_new instead of
2514 symbol_make, since we may want it to go into the symbol table.
2515 Make the new symbol have internal linkage. If
2516 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2517 symbol with the newly created GAS symbol.
2518 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2519 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2521 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.

2524 (in_signed_range): New function.
2526 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2527 (sparc_ip, label "immediate"): Reject constants for pcrel
2528 instructions only if the relocation type indicates a "call"
2529 instruction and the offset is within range of a "jmpl %g0". If
2530 it's not in range, use the absolute section symbol plus an offset.
2531 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2533 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2535 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2538 * configure.in: Eliminated all targets using obj-coff but not
2539 defining BFD_ASSEMBLER; I think all such targets that are
2540 supported will be matched by real CPU-OS combinations earlier in
2542 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2543 some comments about the dpx2 configuration, but left it disabled,
2544 since it couldn't be reached before.
2545 (target a29k-amd-ebmonold): Deleted.
2547 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2555 the 'j' operand if there are no further alternatives for this
2558 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2559 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2560 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2562 * config/tc-mips.c (mips_align): Take new argument, label, and use
2563 it instead of global insn_label.
2564 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2565 call to mips_emit_delay and pass it to mips_align.
2567 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2569 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2571 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2572 argument to a .callinfo directive. Don't loop forever on errors.
2574 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2575 use pre-defined registers as arguments.

2579 * write.c (write_object_file): Check both S_IS_LOCAL and
2580 S_IS_EXTERNAL when deciding whether to discard a symbol.
2582 * config-gas.com: Scan Makefile.in, not version.c, for current
2583 version number. Delete all versions of temp files when finished
2584 with them. Create config.h.
2586 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2587 values to reduce number of lookups with S_GET_VALUE. Skip debug
2588 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2589 holger@botbso.rhein-main.de.)
2590 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2591 field. (Also from Holger Teutsch.) Watch for a would-be register
2592 mask that spans frags.
2594 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2595 this_base, not line_base. (Patch from Andreas Arens,
2596 ari@obelix.av.rwth-aachen.de.)
2598 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2599 look local if they're exported or undefined. Used to be done for
2602 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2603 Get it from the looked-up symbol, instead of using the string from
2604 the input stream, which is no longer null-terminated.
2605 (LEX_PCT): New macro, defaults to 0.
2606 (lex_type): Use it for `%'.
2608 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2609 (vip_op): Now static, and returns void. Callers changed. Added
2611 (vip): Ditto. Call as_fatal directly if a program bug is

2658 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2659 0xffff for 'j' to be compatible with MIPS assembler. These

4729 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4731 * configure.in: Set bfd_gas for all sparc targets. Added facility
4732 for keeping or rejecting configurations still under development;
4733 default is to assume production environment, and reject configs
4734 still being worked on. Mark Elf configurations (except sparc and
4735 i386) as developmental. Deleted cases matching some generic names
4736 in favor of more specific names. (E.g., when we get Alpha

4753 through inclusion of tc-hppa.h. Delete all forward declarations
4754 for functions only used within tc-hppa.c, likewise for structures,
4755 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4756 conditional code in a few small places.
4758 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4759 structures, global variables, forward declarations together.

4761 conditional code -- try to group conditional code together
4762 into a few places. Make all functions and variables which
4763 are only used within tc-hppa.c static. PARAMize all functions.
4764 Add comments to functions. Delete unused functions, variables,
4765 #defines, etc. Delete unused members within structures. Delete
4766 ldil;ble hacks -- it is believed they were installed to work
4767 around old gas bugs. Avoid using mixed case for local
4768 functions, variables, and structures. Fix formatting problems
4769 not found by GNU-indent. Add FIXME notices for things which
4770 should be worked on the near future. Delete lots of old
4771 useless (1.36 PA-SOM) code.

4785 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
4786 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
4788 * config/tc-hppa.c: Likewise.
4790 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4791 of elf32_symbol_type.
4792 (pa_export_args): Likewise.
4793 (elf_hppa_final_processing): Likewise.

4800 a multiple of the section alignment rather than always a
4803 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4804 bits are zero (eg they specify no relocations), then do not even
4805 bother adding their entries to thesymextn section.

4846 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
4847 call strchr for each character to see if it is a special char,
4848 instead add a second loop over special_chars. Set alignment
4849 of text, data and bss sections to 4.
4850 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4852 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4853 ELF, since the ELF object format does not have these type of
4854 relocations. Change the abort into as as_bad and return
4855 BFD_RELOC_NONE to silence compiler warnings.
4856 (md_assemble): Keep track of the instruction size. Allow white
4857 space between the $ and the constant for compatibility with older
4858 gases and other assemblers.

7242 a29k .bss section; the mondfe program doesn't like it.

7263 source directory, if that's not the current directory.
7265 * configure.in (per-host): Accept MIPS host with BSD version

7291 avoid some redefinition complaints on some systems.
7292 (const, volatile): Don't need these conditionally defined if we
7293 use CONST and VOLATILE from ansidecl.h.
7294 (seg_name): Use CONST, not const.
7296 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7298 * config/tc-mips.c: Reindented to GNU standards.
7300 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7302 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7303 (fixup_segment): Add a29k special case; the linker is not prepared
7304 to see a segment offset here.
7306 * app.c (do_scrub_next_char): Added new state, 10, modifying state

7309 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7311 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7312 srcdir, might be in objdir.
7314 * doc/Makefile.in: dvi depends on as.dvi

7342 dropping a space immediately following an identifier.
7343 * expr.c, write.c: Rewrote assert expressions to not use multiple
7344 lines; I don't think that can be done portably.
7345 * config/tc-mips.c (macro): Use $AT if target register is zero in
7346 load instruction, which it can be for a floating point load.

7359 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
7360 z8k-opc.h, not z8k.h.
7362 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
7365 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

7416 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

7420 prototypes for all static functions. Moved existing minimal
7421 debugging format support info #ifndef OBJ_ECOFF blocks.

7470 * make-gas.com: Find obstack.obj if it's not in the current
7472 * read.c (s_ignore): Don't declare is_end_of_line. It's
7473 redundant, and triggers a VMS gcc compiler bug.
7475 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7476 current segment as an argument. (Ignored in all cases but VMS.)
7477 All callers and definitions changed.
7479 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)

7804 * expr.c (operand): If character other than comma or newline is a
7805 logical end-of-line character, use the newline case.
7806 From Eric Youngdale:
7807 (operand): Set X_add_number field for floating-point numbers.
7808 (operand): Treat zero byte as end-of-operand.
7810 * configure.in (per-target): Look for with_bfd_assembler option.
7811 For now, only accept "no", until the merge is done.
7813 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7814 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7820 * expr.c: Add "const" modifier to hex_value.
7821 * symbols.c: Finish conversion to S_* macros in the VMS only

7823 md_[long,short]_jump_size. Remove declaration of const_flag
7824 (which will be declared in obj-vms.h).
7825 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7826 Fix arguments to VMS_write_object_file.
7827 * config-gas.com: New file. Script for VMS systems to set up the
7828 configuration to build gas for VMS, and create config.status.
7829 * make-gas.com: Redone to work with new scheme.
7830 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7832 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7833 will swap bytes if needed on a big endian system. Use throughout
7835 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7836 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7837 types of malformed stabs. Change parsing algorithm so that we are
7838 more certain of having all of the information that we need on hand.
7839 * obj-vms.c (final_forward_reference): New function, used to help

7858 SEG_DATA or SEG_E1 if needed.
7859 (s_lcomm): Likewise with bss_section.
7860 (s_fill): Use memset, not bzero.
7862 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7884 (big_section, reg_section, pass1_section, diff_section,
7885 absent_section, text_section, data_section, bss_section): If
7886 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7887 mapping to segT enum values.
7888 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7889 if these are used or defined, if BFD_ASSEMBLER.
7890 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7891 subseg_new split into two functions.
7892 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7894 * as.h (volatile): Don't define if already defined.
7895 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7898 declare with format attribute for -Wformat checking.
7900 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7902 * app.c, config/tc-*.c: Don't include read.h, since it is already
7905 * These are based on patches from Minh Tran-le
7906 <mtranle@paris.intellicorp.com>.
7907 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7908 obj_format coffbfd and gas_target i386coff for target.

7910 * config/i386aix.mt: Removed (no longer used).
7911 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7913 (LDFLAGS): Added, defined as -shlib.
7914 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7915 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7916 (DOT_LABEL_PREFIX): Define.
7917 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7918 name rather than L0\001.
7919 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7921 * symbols.c, symbols.h (local_bss_counter): Removed.
7922 * write.c (write_object_file): bss no longer uses
7923 local_bss_counter. Pass correct data and bss size to
7924 VMS_write_object_file.
7925 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7926 argument, rather than using local_bss_counter.

7930 (size_section): Restored sanity check.
7931 (do_relocs_for): Base section address on s_paddr rather than
7932 computing it. Adjust a29k R_IHIHALF special case to account for
7933 section paddr (used to require paddr to be zero). If there are no
7934 reclos, set s_relptr to 0. Set relocation size in object_headers.
7935 (fill_section): Always set s_vaddr here, removing
7936 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

7942 H_{SET,GET}_* macros.
7943 (do_linenos_for): Set lineno size in object_headers.
7944 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7945 set s_vaddr here. If string_byte_count remains 4, set it back to
7946 0, and only write strings out if there are some. Call
7947 fill_section before do_relocs_for and do_linenos_for.
7948 (obj_coff_section): Handle optional quoted second argument giving
7949 section characteristics.

7977 * config/obj-coff.h: Don't use #elif.
7979 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

8019 (yank_symbols): Don't merge labels.
8020 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8166 could be doing emulation.
8168 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8171 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8241 * Support for i386-sysv.
8242 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8280 * tc-z8k.c: lots of bug fixes
8282 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8284 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8285 #elif, since it is not supported by old compilers.
8286 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8287 couple of expressions in tc-m68k.c.
8289 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

8315 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8317 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8318 sections starting from zero, rather than making them consecutive.
8319 This makes subsequent reloc calculations easier, esp if the object
8320 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8321 allocate lcomm in .data rather than in .bss. It seems that some
8322 tools can't cope with a non-zero sized bss before linkage.

8345 * Makefile.in (install): if $(tooldir) exists, install as in
8348 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8350 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8351 .word is < -32768 or > 32767. The -J flag causes the error to be
8352 ignored. This is to catch over-sized switches generated by gcc on
8353 systems which don't support the broken .word hack.
8354 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8355 write.c (fixup_segment): check for signed .word overflow if
8356 WARN_SIGNED_OVERFLOW_WORD.
8358 * write.c (fixup_segment): fixed missing parens in expression
8359 checking for byte or word overflow.

8375 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8377 * input-scrub.c (input_scrub_push): call input_file_begin, not
8379 messages.c (as_perror): print ": " between the passed in error and
8380 the strerror, like perror does.
8382 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8384 * Makefile.in: use gas_target instead of modifying target_cpu.
8385 From Steve Chamberlain:
8386 Makefile.in: Handle m68*-*-coff*.
8387 read.c, read.h: add mult argument to s_space
8389 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8390 Motorola and MIT syntax; gas can now assemble either type of

8398 (write_object_file) call fixup_mdeps
8399 (fixup_segment) set fx_subsy to 0.
8400 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8402 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8405 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8407 * Makefile.in (LIBS): Include opcode library.
8409 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

8429 tc-i960.c (md_ri_to_chars): Always output bout object file in
8430 little endian byte order (used to use endianness of host).
8432 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8434 * config/tc-m68k.c (init_table): Now const. Always include 68851
8435 data, so that "bc" is available to 68040 cache instructions.
8436 Added "tt0", "tt1", and 68ec030 variants.
8437 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8438 (enum _register): Added TT0, TT1.
8439 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8440 line number correctly in "internal error" messages. Don't print
8441 architecture-mismatch message for operand errors.

8470 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8472 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8473 written with indirection on the last two operands, which can be
8474 either data or address registers. Added a new operand type 'r'
8475 which accepts either register type. Added '(' to notend stuff in
8476 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8588 characteristics have been), default to 68020. Don't need extra
8589 quotes around error string.

8671 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
8673 * write.c (write_object_file): keep the fix_tail clean, which
8674 fixes a bug in -R where relocations were being lost.

8722 * write.c (write_object_file): For b.out format, round up section
8723 start addresses to match required alignment.
8725 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8727 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8728 where gcc looks for it.
8730 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8732 * Makefile.in: Changed some lines to be less confusing for some

8802 * expr.c (operand): if can't work out what sort of operand it is,
8803 then look through FLT_CHARS for a hint.
8805 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8807 * Makefile.in, configure.in: removed traces of namesubdir,

8811 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8812 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8813 copyrights to '92, changed some from Cygnus to FSF.
8815 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8817 * expr.c: If an expression is single comma, then return with
8818 SEG_ABSENT rather than an error - since the sparc front end does
8819 really strange things with things like fbge,a
8821 * as.h: include bfd.h if using many sections
8822 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8823 local labels didn't work.
8824 * listing.c (list_symbol_table): don't core dump when there's no
8826 * write.c, write.h: call fix_new with the right number of args on
8828 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8831 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8833 * app.c: MRI compatibility - allow single quote to start a string.
8834 * as.c: fix typo recently introduced.
8835 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8836 * expr.c: Much rewriting, to accomodate MRI syntax for
8837 expressions. Also easier to read now.
8838 * listing.c: Put back defuns
8839 * read.c: modified to accept MRI syntax, put back listing pseudo
8840 ops so that an assembler built with NO_LISTING ignores list ops
8842 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8843 machine is a SPARC or a 29K.
8844 * config/obj-aout.c: added s_sect pseudo op
8845 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8846 fill in the timestamp.
8847 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8848 anymore, define all the relocs which the tc-<x> bit will use so we
8849 can translate from them to the coff types.
8850 * config/tc-a29k.c: reloc_type isn't ane enum any more
8851 * config/tc-m68k.c: Added NO_RELOC definition.
8853 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8855 * Makefile.in: put header files before C source for TAGS; remove
8856 references to non-existent syscalls.h.
8858 * read.c, write.c subsegs.c: back out the .bss changes.
8860 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8862 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8866 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8868 * symbols.c (local_label_name): symbols now start with ^A.
8870 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8871 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8872 generate these sections. .align: will use NOP_OPCODE or 0
8873 for padding. This is just for being nice to the
8876 * expr.c (operand): changed to generate local label "\001L0"
8877 starting with a ^A so that it is recognized as a local label.
8879 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8881 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8882 i/o opcodes - inb, inw, outb and outw. string manipulation with
8883 att syntax - scmp, slod, smov, ssca, ssto.
8885 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8886 to just after .file .
8888 In obj_crawl_symbol_chain() where it tries to put the external
8889 symbols apart, with the condition:
8890 (!S_IS_DEFINED(symbolP) &&
8891 !S_IS_DEBUG(symbolP) &&
8892 !SF_GET_STATICS(symbolP))
8893 it was moving too many symbols out. So I switch it back to the
8895 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8897 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8898 so that we don't use the F_RELFLG which make the linker complain
8899 that somebody has stripped the relocation info.
8901 Also, the AIX ld program require that the relocation table
8902 is sorted by r_vaddr like the standard ATT assembler does.
8904 [he also changed the sizeof(struct ...)'s into the coff
8905 style FOOSZ macros. I'm not sure this is right, but I can't
8906 remember why. xoxorich.]
8908 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8910 * Makefile.in, configure.in, doc: use the doc. Build it, install

8915 * read.c: white space and comments only.
8917 * configure.in: use the new atof-ns32.c for ns32k.
8919 * write.c: comment change only.
8921 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8922 aren't yet integrated.
8924 * tc-i860.[hc]: blew off the dust. Something must still be done
8925 about conflicting relocation types.
8927 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8930 * tc-i960.c, tc-sparc.c: white space and comments only.
8932 * tc-a29k.h: delete duplicate macro definition.
8934 * new file atof-ns32k.c copied from hack's last unreleased gas.
8936 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
