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

599 (print_expr_1): Fix whitespace before printing X_add_number.
601 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
602 not symbol_new, for symbols holding expression values.
603 * expr.h (make_expr_symbol): Move declaration here.
604 * write.c (fix_new_exp): Handle O_add by creating an
605 expression-valued symbol, and calling fix_new_exp recursively.
606 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
607 undefined symbol and a constant, fold the constant into the fixup,
608 and refer to the undefined symbol directly. Then process the
609 fixup again from scratch.
610 (write_object_file): Before calling adjust_reloc_syms, make a pass
611 through the symbol list trying to resolve values.
613 * write.c (print_fixup): New routine, for debugging.
614 (write_relocs): Call bfd_install_relocation. Deleted various
615 hacks for working around problems with bfd_perform_relocation.

623 * config/tc-mips.c: Include subsegs.h.
624 (md_apply_fix): If an unconditional b or bal overflows, and we are
625 not assembling PIC code, replace it with a j or jal.
627 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
628 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

632 * write.c (write_relocs): Add file name and line number to
633 as_fatal calls. Handle bfd_reloc_overflow case specifically when
634 RELOC_EXPANSION_POSSIBLE.
636 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
638 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
639 here. Use them for deciding which PRINTF*LIKE macro definitions
641 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
642 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
643 default definitions matching what we were doing before.
644 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
645 always use the varargs form if not using stdarg. It's safe to
646 always use vfprintf, because libiberty will provide it if the
647 native system doesn't. Also, always make format be const.
648 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

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

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

712 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
713 from the csect of the enclosing block.
715 * config/tc-mips.c (insns_since_cache_access): Remove.

719 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
721 * config/tc-mips.c (md_shortopts): Remove E.
722 (md_longopts): Add EB and EL.
723 (md_parse_option): Handle -EB and -EL as separate options, rather
724 than as a single -E option with an argument.
726 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
728 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
729 involving global symbols too.
731 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
733 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
735 * configure.in: Test for remove, not delete. Fix cross-assembler

745 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
747 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
748 many others): new macros; values obtained from "DSTRECRDS.SDL".
749 * config/obj-vms.h (various): use them.
750 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
751 representation (only enum bitfields can avoid being bitstrings).
752 (bitfield_suffix, setup_basic_type): new routines.
753 (VMS_typedef_parse): use them. Now recognize bitfields of all
754 integral types, not just type `int'. Caveat: the representation
755 used for bitfields still does not work for objects placed in
756 registers, and gcc's optimizer sometimes puts small structs there.
758 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
760 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
762 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
763 (tc_frob_label): define this to call vms_check_for_special_label,
764 and declare the latter.

767 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
768 (vms_check_for_special_label): new routine (tc_frob_label).
769 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
770 and `gcc2_compiled.' labels; they won't reach here any more.
771 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
772 double', use `vax_g_doubles' flag to select type of double.
773 (VMS_write_object_file) [traceback setup]: don't pass symbols
774 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
775 and TBT_Routine_End functions.
777 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
779 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
780 S_GET_VALUE() to avoid many repeated function calls.
781 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
782 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
783 gets requested. [All the HACK_DEC_C_STARTUP code appears to
784 be obsolete; gcc does it automatically for vms target. It's
785 also misnamed, because it is for the "VAX C" run-time library,
786 not the newer "DEC C" one which has much different startup code.]
787 {various}: use `S_SET_xxx(symbol,new_value)' rather than
788 `S_GET_xxx(symbol) = new_value'.

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

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

892 Update for autoconf 1.118:
893 * gdbinit.in: New file, created from old .gdbinit.
895 * aclocal.m4 (GAS_GDBINIT): Deleted.
896 * configure.in: Don't use it. Instead, generate .gdbinit from
897 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
898 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
899 to ensure that older versions of autoconf aren't used.
900 * Makefile.in: Added @configure_input@ line.

951 fixup is not local, to prevent relocations against externals from
953 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
954 disp_reloc field to reloc() function, and use TC_RELOC to generate
955 value to pass to fix_new_exp.
956 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
958 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

1913 (load_insn): New macro.
1914 (load_insn_table): New function.

2334 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2336 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2338 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2339 source files from other directories into objects in the current
2340 directory, and specify PSECT attributes explicitly to linker.
2341 Also added missing label.

2374 * subsegs.c (subsegs_begin): Call memset with args in the correct
2376 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2377 to NULL instead of 0.

2406 (hppa_tc_symbol): Likewise.
2408 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2409 elf_tc_make_sections stuff. It was there to support PA braindamage
2410 which has been fixed, and in the case of elf_tc_make_sections is
2411 redundant with elf_tc_final_processing.

2431 don't spew remainder of input file in error message.
2432 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2433 message with reloc type and try to process remainder of file.

2445 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2446 flag rather than signedp field. Only permit extended range if
2447 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2448 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2450 * config/tc-ppc.c (ppc_size): New static variable.
2451 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2452 (md_begin): If an instruction has a size specific flag set, only
2453 add it if we are assembling that size.

2457 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2458 cross section PC relative relocs right for COFF and ELF.
2460 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2462 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2485 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2486 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2488 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2489 branch with an instruction that uses $at, in case the branch is
2491 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2492 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2493 to make it pcrel_offset.
2494 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2495 reloc->address; another gruesome hack to get gas reloc handling to
2498 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2500 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2503 (emit_insn): New function.
2504 (md_assemble): Call it.
2505 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2507 (lituse_pending): New variable. Set by anything that generates a
2508 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2509 tested by code that might want to emit a LITUSE reloc.
2510 (emit_unaligned_io): New function. Currently calls md_assemble,
2511 but it should eventually be converted to generate the insn itself
2512 and call emit_insn directly.
2513 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2514 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2515 emit_bis_r): Likewise.
2516 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2517 (alpha_ip, label get_macro): Don't emit the final instruction if
2519 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2520 unaligned memory access macros.

2524 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2526 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2527 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2528 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2540 * config/tc-mips.c (enum mips_pic_level): New enum.
2541 (mips_pic): Change from int to enum mips_pic_level. Change all
2542 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2543 (load_address): Handle EMBEDDED_PIC.
2544 (macro): Handle EMBEDDED_PIC in all PIC cases.
2545 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2546 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2547 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2548 works). Do not permit -G with SVR4_PIC.
2549 (s_abicalls): Warn if -G was used, and force -G 0.
2550 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2551 anything but a.out, not just for ELF. For ECOFF, don't generate a
2552 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2554 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2556 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2558 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2559 parameters to avoid losing when compiling with HP CC.

2562 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2564 * Makefile.in (config-stamp): If `defs' is defined, emit a
2565 preprocessor directive to create a macro named by this value into
2566 config.new; don't explicitly go for BFD_ASSEMBLER.
2567 * configure.in: Define `defs', not `BFDDEF'. Set it to
2568 MANY_SEGMENTS for any obj-coffbfd target.
2569 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2570 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2572 (LOCAL_LOADLIBES): Deleted.
2573 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2574 * config/m88kcoff.mt (TDEFINES): Ditto.

2600 bfd_set_symtab is called.
2601 (dump_section_relocs): Note whether a symbol is a section symbol
2603 (adjust_reloc_syms): For now, always supply an absolute symbol for
2604 fixups without symbols but not yet `done'. Use section_symbol to
2605 get the symbol, instead of going directly for abs_symbol.
2606 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2607 reloc is not a section symbol and is not in the symbol table.
2608 (set_symtab): New function, broken out from write_object_file.
2609 Counts symbol table instead of relying on an earlier count.
2610 (write_object_file): Call set_symtab, but do it after potentially
2611 invoking the *_frob_file macros. Don't bother counting symbols.
2612 Call symbol_remove, instead of expanding it in place. Moved the
2613 conditionalized `object_file_size' declaration down to
2614 conditionalized block where it's used. When using the absolute
2615 symbol for a fixup without a symbol, set sy_used_in_reloc.
2616 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2617 the correct symbol for the absolute section.
2619 * subsegs.c (section_symbol): Use symbol_new instead of
2620 symbol_make, since we may want it to go into the symbol table.
2621 Make the new symbol have internal linkage. If
2622 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2623 symbol with the newly created GAS symbol.
2624 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2625 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2630 (in_signed_range): New function.
2632 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2633 (sparc_ip, label "immediate"): Reject constants for pcrel
2634 instructions only if the relocation type indicates a "call"
2635 instruction and the offset is within range of a "jmpl %g0". If
2636 it's not in range, use the absolute section symbol plus an offset.
2637 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2639 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2641 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2644 * configure.in: Eliminated all targets using obj-coff but not
2645 defining BFD_ASSEMBLER; I think all such targets that are
2646 supported will be matched by real CPU-OS combinations earlier in
2648 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2649 some comments about the dpx2 configuration, but left it disabled,
2650 since it couldn't be reached before.
2651 (target a29k-amd-ebmonold): Deleted.
2653 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2661 the 'j' operand if there are no further alternatives for this
2664 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2665 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2666 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2668 * config/tc-mips.c (mips_align): Take new argument, label, and use
2669 it instead of global insn_label.
2670 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2671 call to mips_emit_delay and pass it to mips_align.
2673 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2675 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2677 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2678 argument to a .callinfo directive. Don't loop forever on errors.
2680 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2681 use pre-defined registers as arguments.

2686 S_IS_EXTERNAL when deciding whether to discard a symbol.
2688 * config-gas.com: Scan Makefile.in, not version.c, for current
2689 version number. Delete all versions of temp files when finished
2690 with them. Create config.h.
2692 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2693 values to reduce number of lookups with S_GET_VALUE. Skip debug
2694 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2695 holger@botbso.rhein-main.de.)
2696 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2697 field. (Also from Holger Teutsch.) Watch for a would-be register
2698 mask that spans frags.
2700 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2701 this_base, not line_base. (Patch from Andreas Arens,
2702 ari@obelix.av.rwth-aachen.de.)
2704 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2705 look local if they're exported or undefined. Used to be done for
2708 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2709 Get it from the looked-up symbol, instead of using the string from
2710 the input stream, which is no longer null-terminated.
2711 (LEX_PCT): New macro, defaults to 0.
2712 (lex_type): Use it for `%'.
2714 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2715 (vip_op): Now static, and returns void. Callers changed. Added

2764 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2765 0xffff for 'j' to be compatible with MIPS assembler. These
2766 numbers are actually treated as negative.

2777 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
2778 work. It still doesn't. It now fails to compile, instead of
2779 silently compiling to do nothing.
2780 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
2782 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4721 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4722 the table, require that the one without bit 0x1000000 set come
4723 first. Require further that it be case 'b' or 'P'. The a29k
4724 opcode table already meets these constraints.
4725 (machine_ip): When handling case 'i' or 'A', make sure that the

4781 * write.c (write_relocs): For relocs that are pc_relative and
4782 pcrel_offset and not partial_inplace, adjust reloc->addend to

4833 OPTIONAL_REGISTER_PREFIX if either is already defined.
4835 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4837 * configure.in: Set bfd_gas for all sparc targets. Added facility
4838 for keeping or rejecting configurations still under development;
4839 default is to assume production environment, and reject configs
4840 still being worked on. Mark Elf configurations (except sparc and
4841 i386) as developmental. Deleted cases matching some generic names
4842 in favor of more specific names. (E.g., when we get Alpha

4860 for functions only used within tc-hppa.c, likewise for structures,
4861 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4862 conditional code in a few small places.
4864 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4865 structures, global variables, forward declarations together.

4868 into a few places. Make all functions and variables which
4869 are only used within tc-hppa.c static. PARAMize all functions.
4870 Add comments to functions. Delete unused functions, variables,
4871 #defines, etc. Delete unused members within structures. Delete
4872 ldil;ble hacks -- it is believed they were installed to work
4873 around old gas bugs. Avoid using mixed case for local
4874 functions, variables, and structures. Fix formatting problems
4875 not found by GNU-indent. Add FIXME notices for things which
4876 should be worked on the near future. Delete lots of old
4877 useless (1.36 PA-SOM) code.

4906 a multiple of the section alignment rather than always a
4909 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4910 bits are zero (eg they specify no relocations), then do not even
4911 bother adding their entries to thesymextn section.

4955 of text, data and bss sections to 4.
4956 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4958 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4959 ELF, since the ELF object format does not have these type of
4960 relocations. Change the abort into as as_bad and return
4961 BFD_RELOC_NONE to silence compiler warnings.
4962 (md_assemble): Keep track of the instruction size. Allow white
4963 space between the $ and the constant for compatibility with older
4964 gases and other assemblers.

6040 type and to delay the computation of the expression until the
6041 value is actually needed. This permits setting symbols to values

7397 avoid some redefinition complaints on some systems.

7408 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7415 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7417 * Makefile.in: add dvi target; as-$(config).texinfo might live in

7448 dropping a space immediately following an identifier.

7450 lines; I don't think that can be done portably.
7451 * config/tc-mips.c (macro): Use $AT if target register is zero in

7484 (ALL_CFLAGS): No longer define TARGET_CPU.
7486 * Makefile.in (check): Print a message, instead of quitting
7489 * as.c (main): Don't catch any signals, for now.

7526 prototypes for all static functions. Moved existing minimal
7527 debugging format support info #ifndef OBJ_ECOFF blocks.

7576 * make-gas.com: Find obstack.obj if it's not in the current
7578 * read.c (s_ignore): Don't declare is_end_of_line. It's
7579 redundant, and triggers a VMS gcc compiler bug.
7581 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7582 current segment as an argument. (Ignored in all cases but VMS.)
7583 All callers and definitions changed.

7607 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7610 * configure.in: mips-bsd configuration was missing format spec.
7613 * Makefile.in (Makefile): Depends on configure.in.
7615 * config/tc-mips.c (append_insn): Don't check for alignment of
7616 frag in memory; alignment of instructions in section is a separate

7636 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7637 constants are accepted, but symbolic values are not. GCC will not
7638 generate the latter currently.
7640 * frags.c (frag_init): New function.
7641 (zero_address_frag, bss_address_frag): Now initialized at run
7643 * as.c (main): Call frag_init.

7914 (operand): Treat zero byte as end-of-operand.
7916 * configure.in (per-target): Look for with_bfd_assembler option.
7917 For now, only accept "no", until the merge is done.
7919 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7920 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7921 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7922 * read.c: Finish conversion to S_* macros in the VMS only
7923 parts of the program. Add "const" modifier to hex_value.
7924 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7926 * expr.c: Add "const" modifier to hex_value.
7927 * symbols.c: Finish conversion to S_* macros in the VMS only
7928 parts of the program. Add "const" modifier to
7929 md_[long,short]_jump_size. Remove declaration of const_flag
7930 (which will be declared in obj-vms.h).
7931 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7932 Fix arguments to VMS_write_object_file.
7933 * config-gas.com: New file. Script for VMS systems to set up the
7934 configuration to build gas for VMS, and create config.status.
7935 * make-gas.com: Redone to work with new scheme.

7941 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7942 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7943 types of malformed stabs. Change parsing algorithm so that we are
7944 more certain of having all of the information that we need on hand.
7945 * obj-vms.c (final_forward_reference): New function, used to help
7946 resolve the data types of as many struct elements as possible
7947 when some part of the struct is not fully defined by the compiler.
7948 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7950 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7951 as symbols as well in the object file. Look for external functions
7952 that start with "__vt.", and turn them into variables, since the
7953 g++ compiler is incapable of doing this.
7954 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7956 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7957 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7958 have the name of the source file yet.
7959 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7961 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7963 * read.c (s_data): Always use "data_section", since it'll map to
7964 SEG_DATA or SEG_E1 if needed.
7965 (s_lcomm): Likewise with bss_section.
7966 (s_fill): Use memset, not bzero.
7968 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7980 * Changes for BFD_ASSEMBLER:
7981 * obj.h (obj_crawl_symbol_chain): Declare only if not
7983 (obj_header_append, obj_pre_write_hook): Ditto.
7984 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7985 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
7986 (segment_name) If BFD_ASSEMBLER, look up BFD section name;

7990 (big_section, reg_section, pass1_section, diff_section,
7991 absent_section, text_section, data_section, bss_section): If
7992 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7993 mapping to segT enum values.

7995 if these are used or defined, if BFD_ASSEMBLER.
7996 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7997 subseg_new split into two functions.
7998 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8000 * as.h (volatile): Don't define if already defined.
8001 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8003 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8004 declare with format attribute for -Wformat checking.
8006 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8008 * app.c, config/tc-*.c: Don't include read.h, since it is already
8011 * These are based on patches from Minh Tran-le
8012 <mtranle@paris.intellicorp.com>.
8013 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8014 obj_format coffbfd and gas_target i386coff for target.
8015 (i[34]86-*-isc*): New host (uses sysv).
8016 * config/i386aix.mt: Removed (no longer used).
8017 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8019 (LDFLAGS): Added, defined as -shlib.
8020 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8021 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8022 (DOT_LABEL_PREFIX): Define.
8023 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8024 name rather than L0\001.

8027 * symbols.c, symbols.h (local_bss_counter): Removed.
8028 * write.c (write_object_file): bss no longer uses

8036 (size_section): Restored sanity check.
8037 (do_relocs_for): Base section address on s_paddr rather than
8038 computing it. Adjust a29k R_IHIHALF special case to account for
8039 section paddr (used to require paddr to be zero). If there are no
8040 reclos, set s_relptr to 0. Set relocation size in object_headers.
8041 (fill_section): Always set s_vaddr here, removing
8042 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8043 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8044 Set STYP_INFO for .comment.

8049 (do_linenos_for): Set lineno size in object_headers.
8050 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8051 set s_vaddr here. If string_byte_count remains 4, set it back to
8052 0, and only write strings out if there are some. Call
8053 fill_section before do_relocs_for and do_linenos_for.
8054 (obj_coff_section): Handle optional quoted second argument giving
8055 section characteristics.
8056 (obj_coff_bss): Added to handle .bss.
8057 (obj_coff_ident): Added to handle .ident (puts string in .comment

8060 (fixup_mdeps): Change to segment. Call frag_wane after
8062 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8063 adjustment (already happened only for common symbols, but this is
8065 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8077 (do_scrub_next_char): For \", return " not '.
8078 (symbol_chars): Now const.
8080 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8081 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8083 * config/obj-coff.h: Don't use #elif.
8085 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8086 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8113 using ZERO_BASED_SEGMENTS.
8114 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8115 never set segment address for SEG_E2 (.bss) and don't write out
8116 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8117 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8118 definitions, and don't merge tags with non-tags. Check for .bf
8119 rather than just checking whether the second character is b and
8120 the third character is f.
8121 (obj_coff_val): gcc can generate values which we don't handle
8122 correctly; discard information for now, since it only affects the
8123 debugging information.

8125 (yank_symbols): Don't merge labels.
8126 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8274 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8277 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8306 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8308 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8309 constant will not fit in an immediate field.
8310 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8345 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8347 * Support for i386-sysv.
8348 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8386 * tc-z8k.c: lots of bug fixes
8388 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8390 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8391 #elif, since it is not supported by old compilers.
8392 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8393 couple of expressions in tc-m68k.c.
8395 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8397 * read.c (cons): If NO_RELOC is defined, use it.
8399 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8401 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8403 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8404 local labels to start with a .) and set REGISTER_PREFIX to %.
8405 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8407 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8409 * messages.c: Comment changes.
8411 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8421 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8423 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8424 sections starting from zero, rather than making them consecutive.
8425 This makes subsequent reloc calculations easier, esp if the object
8426 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8427 allocate lcomm in .data rather than in .bss. It seems that some
8428 tools can't cope with a non-zero sized bss before linkage.

8432 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8433 throughout. That enum no longer means what we thought it meant.

8454 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8456 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8457 .word is < -32768 or > 32767. The -J flag causes the error to be
8458 ignored. This is to catch over-sized switches generated by gcc on
8459 systems which don't support the broken .word hack.
8460 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8461 write.c (fixup_segment): check for signed .word overflow if
8462 WARN_SIGNED_OVERFLOW_WORD.

8491 From Steve Chamberlain:
8492 Makefile.in: Handle m68*-*-coff*.
8493 read.c, read.h: add mult argument to s_space
8495 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

8540 * config/tc-m68k.c (init_table): Now const. Always include 68851
8541 data, so that "bc" is available to 68040 cache instructions.
8542 Added "tt0", "tt1", and 68ec030 variants.
8543 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8544 (enum _register): Added TT0, TT1.
8545 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass

8572 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8573 has already been formatted (but may still contain %-characters).
8576 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8578 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8579 written with indirection on the last two operands, which can be
8580 either data or address registers. Added a new operand type 'r'
8581 which accepts either register type. Added '(' to notend stuff in
8582 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8929 local labels didn't work.
8930 * listing.c (list_symbol_table): don't core dump when there's no
8932 * write.c, write.h: call fix_new with the right number of args on
8934 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8937 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8939 * app.c: MRI compatibility - allow single quote to start a string.
8940 * as.c: fix typo recently introduced.
8941 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8942 * expr.c: Much rewriting, to accomodate MRI syntax for
8943 expressions. Also easier to read now.
8944 * listing.c: Put back defuns
8945 * read.c: modified to accept MRI syntax, put back listing pseudo
8946 ops so that an assembler built with NO_LISTING ignores list ops
8948 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8949 machine is a SPARC or a 29K.
8950 * config/obj-aout.c: added s_sect pseudo op
8951 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8952 fill in the timestamp.
8953 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8954 anymore, define all the relocs which the tc-<x> bit will use so we
8955 can translate from them to the coff types.
8956 * config/tc-a29k.c: reloc_type isn't ane enum any more
8957 * config/tc-m68k.c: Added NO_RELOC definition.
8959 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8961 * Makefile.in: put header files before C source for TAGS; remove
8962 references to non-existent syscalls.h.
8964 * read.c, write.c subsegs.c: back out the .bss changes.
8966 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8968 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8972 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8974 * symbols.c (local_label_name): symbols now start with ^A.
8976 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8977 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8978 generate these sections. .align: will use NOP_OPCODE or 0
8979 for padding. This is just for being nice to the
8982 * expr.c (operand): changed to generate local label "\001L0"
8983 starting with a ^A so that it is recognized as a local label.
8985 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8987 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8988 i/o opcodes - inb, inw, outb and outw. string manipulation with
8989 att syntax - scmp, slod, smov, ssca, ssto.
8991 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8992 to just after .file .
8994 In obj_crawl_symbol_chain() where it tries to put the external
8995 symbols apart, with the condition:
8996 (!S_IS_DEFINED(symbolP) &&
8997 !S_IS_DEBUG(symbolP) &&
8998 !SF_GET_STATICS(symbolP))
8999 it was moving too many symbols out. So I switch it back to the
9001 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9003 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9004 so that we don't use the F_RELFLG which make the linker complain
9005 that somebody has stripped the relocation info.
9007 Also, the AIX ld program require that the relocation table
9008 is sorted by r_vaddr like the standard ATT assembler does.
9010 [he also changed the sizeof(struct ...)'s into the coff
9011 style FOOSZ macros. I'm not sure this is right, but I can't
9012 remember why. xoxorich.]
9014 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9016 * Makefile.in, configure.in, doc: use the doc. Build it, install
9019 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9021 * read.c: white space and comments only.
9023 * configure.in: use the new atof-ns32.c for ns32k.
9025 * write.c: comment change only.
9027 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9028 aren't yet integrated.
9030 * tc-i860.[hc]: blew off the dust. Something must still be done
9031 about conflicting relocation types.
9033 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9036 * tc-i960.c, tc-sparc.c: white space and comments only.
9038 * tc-a29k.h: delete duplicate macro definition.
9040 * new file atof-ns32k.c copied from hack's last unreleased gas.
9042 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9044 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9047 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9048 ChangeLog's prior to this are sketchy at best. I have logs.
9049 They just aren't ChangeLogs.
9056 version-control: never
