533 If PC-relative fixup refers to a PLT entry for a symbol in the
534 current section, don't reduce it.

537 DEBUG5 is defined, print out each fixup before and after
539 (fixup_segment): If DEBUG5 is defined, print out each fixup before
540 and after processing.
541 (print_fixup): Added prototype. Show address on first line. Show

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

573 (S_GET_VALUE): If symbol needs resolving, resolve it.
574 (indent_level): No longer static.
575 (print_symbol_value_1): Don't print frag address if it matches
576 zero_address_frag. Don't print "resolving" if already resolved.
577 Print segment name. Don't call print_expr_1 on an undefined
579 (print_expr_1): Fix whitespace before printing X_add_number.
581 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
582 not symbol_new, for symbols holding expression values.
583 * expr.h (make_expr_symbol): Move declaration here.
584 * write.c (fix_new_exp): Handle O_add by creating an
585 expression-valued symbol, and calling fix_new_exp recursively.
586 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
587 undefined symbol and a constant, fold the constant into the fixup,
588 and refer to the undefined symbol directly. Then process the
589 fixup again from scratch.
590 (write_object_file): Before calling adjust_reloc_syms, make a pass
591 through the symbol list trying to resolve values.
593 * write.c (print_fixup): New routine, for debugging.
594 (write_relocs): Call bfd_install_relocation. Deleted various
595 hacks for working around problems with bfd_perform_relocation.

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

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

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

664 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
665 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
666 zero. Don't call obj_frob_forward_symbol.

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

691 (ppc_es): Clear ppc_current_block.
692 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
693 from the csect of the enclosing block.
695 * config/tc-mips.c (insns_since_cache_access): Remove.
696 (append_insn): Remove setting of insns_since_cache_access, and

699 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
701 * config/tc-mips.c (md_shortopts): Remove E.
702 (md_longopts): Add EB and EL.
703 (md_parse_option): Handle -EB and -EL as separate options, rather
704 than as a single -E option with an argument.
706 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
708 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
709 involving global symbols too.
711 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
713 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
715 * configure.in: Test for remove, not delete. Fix cross-assembler

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

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

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

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

872 Update for autoconf 1.118:
873 * gdbinit.in: New file, created from old .gdbinit.
875 * aclocal.m4 (GAS_GDBINIT): Deleted.
876 * configure.in: Don't use it. Instead, generate .gdbinit from
877 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
878 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
879 to ensure that older versions of autoconf aren't used.
880 * Makefile.in: Added @configure_input@ line.

931 fixup is not local, to prevent relocations against externals from
933 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
934 disp_reloc field to reloc() function, and use TC_RELOC to generate
935 value to pass to fix_new_exp.
936 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
938 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

1913 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
1915 Merged in changes from gas-2.3 net release:
1917 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
1919 * config/obj-vms.c: Replaced unchecked uses of malloc with
1922 * listing.c (list_symbol_table): Only test BFD64, not
1925 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
1926 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.
1928 * config/obj-vms.c: Removed lots of extra semicolons after
1929 compound statements.
1930 (strchr): Don't declare here.
1932 * config/ho-vax.h (realloc): Declare.

1945 VMS debugger now recognizes `long long' variables correctly.
1946 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1947 for gcc2's predefined types "long double" (same as double, as
1948 per gcc's current state), "long long int", "long long unsigned
1949 int", and final `otherwise' case (to avoid uninitialized type
1950 and size fields). [caveat: predefined types "complex int",
1951 "complex float", "complex double", and "complex long double" are
1954 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1955 of 0, because the latter indicates success rather than failure

2386 (hppa_tc_symbol): Likewise.
2388 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2389 elf_tc_make_sections stuff. It was there to support PA braindamage
2390 which has been fixed, and in the case of elf_tc_make_sections is
2391 redundant with elf_tc_final_processing.

2410 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2411 don't spew remainder of input file in error message.
2412 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2413 message with reloc type and try to process remainder of file.
2415 * doc/Makefile.in (install-info-as, install-info-gasp): New
2416 targets, now explicitly checking $(srcdir) for info files.
2417 (install-info): Depend on both of them; do nothing more.

2425 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2426 flag rather than signedp field. Only permit extended range if
2427 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2428 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2430 * config/tc-ppc.c (ppc_size): New static variable.
2431 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2432 (md_begin): If an instruction has a size specific flag set, only
2433 add it if we are assembling that size.
2435 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2437 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2438 cross section PC relative relocs right for COFF and ELF.
2440 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2442 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2443 (OBJ_PROCESS_STAB): Don't define.

2447 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2448 the type of symbol set symbols which happen to be in the absolute
2449 or undefined section.

2453 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2454 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2455 and -many (all architectures).

2465 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2466 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2468 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2469 branch with an instruction that uses $at, in case the branch is
2471 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2472 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2473 to make it pcrel_offset.
2474 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2475 reloc->address; another gruesome hack to get gas reloc handling to
2478 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2480 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2483 (emit_insn): New function.
2484 (md_assemble): Call it.
2485 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2487 (lituse_pending): New variable. Set by anything that generates a
2488 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2489 tested by code that might want to emit a LITUSE reloc.
2490 (emit_unaligned_io): New function. Currently calls md_assemble,
2491 but it should eventually be converted to generate the insn itself
2492 and call emit_insn directly.
2493 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2494 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2495 emit_bis_r): Likewise.
2496 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2497 (alpha_ip, label get_macro): Don't emit the final instruction if
2499 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2500 unaligned memory access macros.
2501 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2502 the value can't be resolved.
2504 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2506 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2507 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2508 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2520 * config/tc-mips.c (enum mips_pic_level): New enum.
2521 (mips_pic): Change from int to enum mips_pic_level. Change all
2522 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2523 (load_address): Handle EMBEDDED_PIC.
2524 (macro): Handle EMBEDDED_PIC in all PIC cases.
2525 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2526 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2527 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2528 works). Do not permit -G with SVR4_PIC.
2529 (s_abicalls): Warn if -G was used, and force -G 0.
2530 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2531 anything but a.out, not just for ELF. For ECOFF, don't generate a
2532 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2534 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2536 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2538 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2539 parameters to avoid losing when compiling with HP CC.
2540 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2542 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2544 * Makefile.in (config-stamp): If `defs' is defined, emit a
2545 preprocessor directive to create a macro named by this value into
2546 config.new; don't explicitly go for BFD_ASSEMBLER.
2547 * configure.in: Define `defs', not `BFDDEF'. Set it to
2548 MANY_SEGMENTS for any obj-coffbfd target.
2549 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2550 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2552 (LOCAL_LOADLIBES): Deleted.
2553 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2554 * config/m88kcoff.mt (TDEFINES): Ditto.

2580 bfd_set_symtab is called.
2581 (dump_section_relocs): Note whether a symbol is a section symbol
2583 (adjust_reloc_syms): For now, always supply an absolute symbol for
2584 fixups without symbols but not yet `done'. Use section_symbol to
2585 get the symbol, instead of going directly for abs_symbol.
2586 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2587 reloc is not a section symbol and is not in the symbol table.
2588 (set_symtab): New function, broken out from write_object_file.
2589 Counts symbol table instead of relying on an earlier count.
2590 (write_object_file): Call set_symtab, but do it after potentially
2591 invoking the *_frob_file macros. Don't bother counting symbols.
2592 Call symbol_remove, instead of expanding it in place. Moved the
2593 conditionalized `object_file_size' declaration down to
2594 conditionalized block where it's used. When using the absolute
2595 symbol for a fixup without a symbol, set sy_used_in_reloc.
2596 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2597 the correct symbol for the absolute section.
2599 * subsegs.c (section_symbol): Use symbol_new instead of
2600 symbol_make, since we may want it to go into the symbol table.
2601 Make the new symbol have internal linkage. If
2602 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2603 symbol with the newly created GAS symbol.
2604 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2605 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2610 (in_signed_range): New function.
2612 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2613 (sparc_ip, label "immediate"): Reject constants for pcrel
2614 instructions only if the relocation type indicates a "call"
2615 instruction and the offset is within range of a "jmpl %g0". If
2616 it's not in range, use the absolute section symbol plus an offset.
2617 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2619 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2621 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2624 * configure.in: Eliminated all targets using obj-coff but not
2625 defining BFD_ASSEMBLER; I think all such targets that are
2626 supported will be matched by real CPU-OS combinations earlier in
2628 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2629 some comments about the dpx2 configuration, but left it disabled,
2630 since it couldn't be reached before.
2631 (target a29k-amd-ebmonold): Deleted.
2633 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2641 the 'j' operand if there are no further alternatives for this
2644 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2645 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2646 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2648 * config/tc-mips.c (mips_align): Take new argument, label, and use
2649 it instead of global insn_label.
2650 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2651 call to mips_emit_delay and pass it to mips_align.
2653 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2655 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2657 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2658 argument to a .callinfo directive. Don't loop forever on errors.
2660 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2661 use pre-defined registers as arguments.

2665 * write.c (write_object_file): Check both S_IS_LOCAL and
2666 S_IS_EXTERNAL when deciding whether to discard a symbol.
2668 * config-gas.com: Scan Makefile.in, not version.c, for current
2669 version number. Delete all versions of temp files when finished
2670 with them. Create config.h.
2672 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2673 values to reduce number of lookups with S_GET_VALUE. Skip debug
2674 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2675 holger@botbso.rhein-main.de.)
2676 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2677 field. (Also from Holger Teutsch.) Watch for a would-be register
2678 mask that spans frags.
2680 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2681 this_base, not line_base. (Patch from Andreas Arens,
2682 ari@obelix.av.rwth-aachen.de.)
2684 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2685 look local if they're exported or undefined. Used to be done for
2688 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2689 Get it from the looked-up symbol, instead of using the string from
2690 the input stream, which is no longer null-terminated.
2691 (LEX_PCT): New macro, defaults to 0.
2692 (lex_type): Use it for `%'.
2694 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2695 (vip_op): Now static, and returns void. Callers changed. Added
2697 (vip): Ditto. Call as_fatal directly if a program bug is

2744 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2745 0xffff for 'j' to be compatible with MIPS assembler. These
2746 numbers are actually treated as negative.

4701 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4702 the table, require that the one without bit 0x1000000 set come
4703 first. Require further that it be case 'b' or 'P'. The a29k
4704 opcode table already meets these constraints.
4705 (machine_ip): When handling case 'i' or 'A', make sure that the
4706 appropriate opcode really exists by looking at the next entry in

4761 * write.c (write_relocs): For relocs that are pc_relative and
4762 pcrel_offset and not partial_inplace, adjust reloc->addend to

4815 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4817 * configure.in: Set bfd_gas for all sparc targets. Added facility
4818 for keeping or rejecting configurations still under development;
4819 default is to assume production environment, and reject configs
4820 still being worked on. Mark Elf configurations (except sparc and
4821 i386) as developmental. Deleted cases matching some generic names
4822 in favor of more specific names. (E.g., when we get Alpha

4840 for functions only used within tc-hppa.c, likewise for structures,
4841 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4842 conditional code in a few small places.
4844 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4845 structures, global variables, forward declarations together.

4847 conditional code -- try to group conditional code together
4848 into a few places. Make all functions and variables which
4849 are only used within tc-hppa.c static. PARAMize all functions.
4850 Add comments to functions. Delete unused functions, variables,
4851 #defines, etc. Delete unused members within structures. Delete
4852 ldil;ble hacks -- it is believed they were installed to work
4853 around old gas bugs. Avoid using mixed case for local
4854 functions, variables, and structures. Fix formatting problems
4855 not found by GNU-indent. Add FIXME notices for things which
4856 should be worked on the near future. Delete lots of old
4857 useless (1.36 PA-SOM) code.

4874 * config/tc-hppa.c: Likewise.
4876 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4877 of elf32_symbol_type.
4878 (pa_export_args): Likewise.

4886 a multiple of the section alignment rather than always a
4889 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4890 bits are zero (eg they specify no relocations), then do not even
4891 bother adding their entries to thesymextn section.

4935 of text, data and bss sections to 4.
4936 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4938 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4939 ELF, since the ELF object format does not have these type of
4940 relocations. Change the abort into as as_bad and return
4941 BFD_RELOC_NONE to silence compiler warnings.
4942 (md_assemble): Keep track of the instruction size. Allow white
4943 space between the $ and the constant for compatibility with older
4944 gases and other assemblers.

7388 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7395 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

7428 dropping a space immediately following an identifier.

7430 lines; I don't think that can be done portably.
7431 * config/tc-mips.c (macro): Use $AT if target register is zero in

7506 prototypes for all static functions. Moved existing minimal
7507 debugging format support info #ifndef OBJ_ECOFF blocks.

7556 * make-gas.com: Find obstack.obj if it's not in the current
7558 * read.c (s_ignore): Don't declare is_end_of_line. It's
7559 redundant, and triggers a VMS gcc compiler bug.
7561 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7562 current segment as an argument. (Ignored in all cases but VMS.)
7563 All callers and definitions changed.

7617 constants are accepted, but symbolic values are not. GCC will not
7618 generate the latter currently.
7620 * frags.c (frag_init): New function.
7621 (zero_address_frag, bss_address_frag): Now initialized at run
7623 * as.c (main): Call frag_init.

7894 (operand): Treat zero byte as end-of-operand.
7896 * configure.in (per-target): Look for with_bfd_assembler option.
7897 For now, only accept "no", until the merge is done.
7899 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7900 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7901 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7902 * read.c: Finish conversion to S_* macros in the VMS only
7903 parts of the program. Add "const" modifier to hex_value.
7904 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7906 * expr.c: Add "const" modifier to hex_value.
7907 * symbols.c: Finish conversion to S_* macros in the VMS only
7908 parts of the program. Add "const" modifier to
7909 md_[long,short]_jump_size. Remove declaration of const_flag
7910 (which will be declared in obj-vms.h).
7911 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7912 Fix arguments to VMS_write_object_file.
7913 * config-gas.com: New file. Script for VMS systems to set up the
7914 configuration to build gas for VMS, and create config.status.

7921 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7922 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7923 types of malformed stabs. Change parsing algorithm so that we are
7924 more certain of having all of the information that we need on hand.

7960 * Changes for BFD_ASSEMBLER:
7961 * obj.h (obj_crawl_symbol_chain): Declare only if not
7963 (obj_header_append, obj_pre_write_hook): Ditto.
7964 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7965 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

7984 declare with format attribute for -Wformat checking.
7986 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7988 * app.c, config/tc-*.c: Don't include read.h, since it is already
7991 * These are based on patches from Minh Tran-le
7992 <mtranle@paris.intellicorp.com>.
7993 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7994 obj_format coffbfd and gas_target i386coff for target.
7995 (i[34]86-*-isc*): New host (uses sysv).
7996 * config/i386aix.mt: Removed (no longer used).
7997 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7999 (LDFLAGS): Added, defined as -shlib.
8000 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8001 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8002 (DOT_LABEL_PREFIX): Define.
8003 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8004 name rather than L0\001.
8005 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8007 * symbols.c, symbols.h (local_bss_counter): Removed.
8008 * write.c (write_object_file): bss no longer uses
8009 local_bss_counter. Pass correct data and bss size to
8010 VMS_write_object_file.

8016 (size_section): Restored sanity check.
8017 (do_relocs_for): Base section address on s_paddr rather than
8018 computing it. Adjust a29k R_IHIHALF special case to account for
8019 section paddr (used to require paddr to be zero). If there are no
8020 reclos, set s_relptr to 0. Set relocation size in object_headers.
8021 (fill_section): Always set s_vaddr here, removing
8022 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8023 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8024 Set STYP_INFO for .comment.

8029 (do_linenos_for): Set lineno size in object_headers.
8030 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8031 set s_vaddr here. If string_byte_count remains 4, set it back to
8032 0, and only write strings out if there are some. Call
8033 fill_section before do_relocs_for and do_linenos_for.
8034 (obj_coff_section): Handle optional quoted second argument giving
8035 section characteristics.
8036 (obj_coff_bss): Added to handle .bss.
8037 (obj_coff_ident): Added to handle .ident (puts string in .comment
8039 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8040 (fixup_mdeps): Change to segment. Call frag_wane after
8042 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8043 adjustment (already happened only for common symbols, but this is
8045 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8057 (do_scrub_next_char): For \", return " not '.
8058 (symbol_chars): Now const.
8060 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8061 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8063 * config/obj-coff.h: Don't use #elif.
8065 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8066 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8093 using ZERO_BASED_SEGMENTS.
8094 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8095 never set segment address for SEG_E2 (.bss) and don't write out
8096 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8097 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8098 definitions, and don't merge tags with non-tags. Check for .bf
8099 rather than just checking whether the second character is b and
8100 the third character is f.
8101 (obj_coff_val): gcc can generate values which we don't handle
8102 correctly; discard information for now, since it only affects the
8103 debugging information.

8105 (yank_symbols): Don't merge labels.
8106 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8286 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8288 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8289 constant will not fit in an immediate field.
8290 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8327 * Support for i386-sysv.
8328 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8365 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
8366 * tc-z8k.c: lots of bug fixes
8368 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8370 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8371 #elif, since it is not supported by old compilers.
8372 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8373 couple of expressions in tc-m68k.c.
8375 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8377 * read.c (cons): If NO_RELOC is defined, use it.
8379 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8381 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8383 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8384 local labels to start with a .) and set REGISTER_PREFIX to %.
8385 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8387 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8389 * messages.c: Comment changes.

8401 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8403 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8404 sections starting from zero, rather than making them consecutive.
8405 This makes subsequent reloc calculations easier, esp if the object
8406 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8407 allocate lcomm in .data rather than in .bss. It seems that some
8408 tools can't cope with a non-zero sized bss before linkage.
8410 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8412 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8426 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8427 Change LIBDEPS dependence to LIBS.
8429 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8431 * Makefile.in (install): if $(tooldir) exists, install as in
8434 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8436 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8437 .word is < -32768 or > 32767. The -J flag causes the error to be
8438 ignored. This is to catch over-sized switches generated by gcc on
8439 systems which don't support the broken .word hack.
8440 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8441 write.c (fixup_segment): check for signed .word overflow if
8442 WARN_SIGNED_OVERFLOW_WORD.

8471 From Steve Chamberlain:
8472 Makefile.in: Handle m68*-*-coff*.
8473 read.c, read.h: add mult argument to s_space
8475 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8476 Motorola and MIT syntax; gas can now assemble either type of
8478 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8520 * config/tc-m68k.c (init_table): Now const. Always include 68851
8521 data, so that "bc" is available to 68040 cache instructions.
8522 Added "tt0", "tt1", and 68ec030 variants.
8523 (md_assemble): Complain if 68000 (only) and 68881 are specified.

8552 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8553 has already been formatted (but may still contain %-characters).
8556 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8558 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8559 written with indirection on the last two operands, which can be
8560 either data or address registers. Added a new operand type 'r'
8561 which accepts either register type. Added '(' to notend stuff in
8562 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8905 really strange things with things like fbge,a
8907 * as.h: include bfd.h if using many sections

8923 expressions. Also easier to read now.
8924 * listing.c: Put back defuns
8925 * read.c: modified to accept MRI syntax, put back listing pseudo
8926 ops so that an assembler built with NO_LISTING ignores list ops

8929 machine is a SPARC or a 29K.
8930 * config/obj-aout.c: added s_sect pseudo op
8931 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8932 fill in the timestamp.
8933 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8934 anymore, define all the relocs which the tc-<x> bit will use so we
8935 can translate from them to the coff types.
8936 * config/tc-a29k.c: reloc_type isn't ane enum any more
8937 * config/tc-m68k.c: Added NO_RELOC definition.
8939 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8941 * Makefile.in: put header files before C source for TAGS; remove
8942 references to non-existent syscalls.h.
8944 * read.c, write.c subsegs.c: back out the .bss changes.
8946 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8948 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

8954 * symbols.c (local_label_name): symbols now start with ^A.
8956 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8957 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8958 generate these sections. .align: will use NOP_OPCODE or 0
8959 for padding. This is just for being nice to the
8962 * expr.c (operand): changed to generate local label "\001L0"
8963 starting with a ^A so that it is recognized as a local label.
8965 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8967 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8968 i/o opcodes - inb, inw, outb and outw. string manipulation with
8969 att syntax - scmp, slod, smov, ssca, ssto.
8971 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8972 to just after .file .
8974 In obj_crawl_symbol_chain() where it tries to put the external
8975 symbols apart, with the condition:
8976 (!S_IS_DEFINED(symbolP) &&
8977 !S_IS_DEBUG(symbolP) &&
8978 !SF_GET_STATICS(symbolP))
8979 it was moving too many symbols out. So I switch it back to the
8981 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8983 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8984 so that we don't use the F_RELFLG which make the linker complain
8985 that somebody has stripped the relocation info.
8987 Also, the AIX ld program require that the relocation table
8988 is sorted by r_vaddr like the standard ATT assembler does.
8990 [he also changed the sizeof(struct ...)'s into the coff
8991 style FOOSZ macros. I'm not sure this is right, but I can't
8992 remember why. xoxorich.]
8994 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8996 * Makefile.in, configure.in, doc: use the doc. Build it, install
8999 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9001 * read.c: white space and comments only.
9003 * configure.in: use the new atof-ns32.c for ns32k.
9005 * write.c: comment change only.
9007 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9008 aren't yet integrated.
9010 * tc-i860.[hc]: blew off the dust. Something must still be done
9011 about conflicting relocation types.
9013 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9016 * tc-i960.c, tc-sparc.c: white space and comments only.
9018 * tc-a29k.h: delete duplicate macro definition.
9020 * new file atof-ns32k.c copied from hack's last unreleased gas.
9022 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9024 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9027 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9028 ChangeLog's prior to this are sketchy at best. I have logs.
9029 They just aren't ChangeLogs.
9036 version-control: never
