518 * configure.in: Set bfd_gas for all sparc targets in one place,
519 instead of separately for each. Correctly handle user-supplied
520 "--enable-bfd-gas" option.
522 * gdbinit.in: Move "break abort" to end, in case gdb complains.
524 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
527 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
528 processing if add_symbol is undefined or in expr_section.
529 (resolve_symbol_value, case O_add): For symbol plus
530 constant-valued symbol, convert to O_symbol and re-reduce.
531 (S_GET_VALUE): If symbol needs resolving, resolve it.
532 (indent_level): No longer static.
533 (print_symbol_value_1): Don't print frag address if it matches
534 zero_address_frag. Don't print "resolving" if already resolved.
535 Print segment name. Don't call print_expr_1 on an undefined
537 (print_expr_1): Fix whitespace before printing X_add_number.
539 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
540 not symbol_new, for symbols holding expression values.
541 * expr.h (make_expr_symbol): Move declaration here.
542 * write.c (fix_new_exp): Handle O_add by creating an
543 expression-valued symbol, and calling fix_new_exp recursively.
544 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
545 undefined symbol and a constant, fold the constant into the fixup,
546 and refer to the undefined symbol directly. Then process the
547 fixup again from scratch.
548 (write_object_file): Before calling adjust_reloc_syms, make a pass
549 through the symbol list trying to resolve values.
551 * write.c (print_fixup): New routine, for debugging.
552 (write_relocs): Call bfd_install_relocation. Deleted various
553 hacks for working around problems with bfd_perform_relocation.

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

619 * config/ho-*.h: Now-unused files deleted.
621 * symbols.c (copy_symbol_attributes): New function. Copies BFD
622 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
623 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
624 zero. Don't call obj_frob_forward_symbol.
625 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

627 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
629 * config/tc-i960.c: Lots of whitespace, comment reformatting,
631 (strchr): Don't declare.
632 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
633 md_estimate_size_before_relax, md_ri_to_chars,
634 md_create_short_jump, md_create_long_jump.
635 (brtab_emit): Use data_section, not SEG_DATA.
637 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
639 * config/vms-conf.h: new file, manually derived from conf.in.
640 * config-gas.com: use it, and eliminate obsolete "host.h".
642 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
644 * config/tc-ppc.c (ppc_current_block): New static variable.

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

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

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

831 * gdbinit.in: New file, created from old .gdbinit.
833 * aclocal.m4 (GAS_GDBINIT): Deleted.
834 * configure.in: Don't use it. Instead, generate .gdbinit from
835 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
836 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
837 to ensure that older versions of autoconf aren't used.

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

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

978 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
979 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
980 message to try to ease confusion about autoconf's

2383 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2384 flag rather than signedp field. Only permit extended range if
2385 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2386 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2388 * config/tc-ppc.c (ppc_size): New static variable.
2389 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2390 (md_begin): If an instruction has a size specific flag set, only
2391 add it if we are assembling that size.
2393 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2395 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2396 cross section PC relative relocs right for COFF and ELF.
2398 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2406 the type of symbol set symbols which happen to be in the absolute
2407 or undefined section.

2411 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2412 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2413 and -many (all architectures).
2415 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2424 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2426 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2427 branch with an instruction that uses $at, in case the branch is
2429 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2430 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2431 to make it pcrel_offset.
2432 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2433 reloc->address; another gruesome hack to get gas reloc handling to
2436 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2438 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2441 (emit_insn): New function.
2442 (md_assemble): Call it.
2443 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2445 (lituse_pending): New variable. Set by anything that generates a
2446 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2447 tested by code that might want to emit a LITUSE reloc.
2448 (emit_unaligned_io): New function. Currently calls md_assemble,
2449 but it should eventually be converted to generate the insn itself
2450 and call emit_insn directly.
2451 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2452 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2453 emit_bis_r): Likewise.

2462 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2464 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2465 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2466 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2468 (mips_force_relocation): New function.
2469 (md_apply_fix): Set fixP->fx_done appropriately.
2470 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2481 (load_address): Handle EMBEDDED_PIC.
2482 (macro): Handle EMBEDDED_PIC in all PIC cases.
2483 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2484 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2485 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2486 works). Do not permit -G with SVR4_PIC.
2487 (s_abicalls): Warn if -G was used, and force -G 0.
2488 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2489 anything but a.out, not just for ELF. For ECOFF, don't generate a
2490 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2492 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2494 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2496 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2497 parameters to avoid losing when compiling with HP CC.
2498 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2500 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2502 * Makefile.in (config-stamp): If `defs' is defined, emit a
2503 preprocessor directive to create a macro named by this value into
2504 config.new; don't explicitly go for BFD_ASSEMBLER.
2505 * configure.in: Define `defs', not `BFDDEF'. Set it to
2506 MANY_SEGMENTS for any obj-coffbfd target.
2507 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2508 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2510 (LOCAL_LOADLIBES): Deleted.
2511 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2512 * config/m88kcoff.mt (TDEFINES): Ditto.
2513 * config/ebmon29k.mt: Deleted.

2516 * config/sparc.mt: Deleted.
2517 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2518 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2519 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2538 bfd_set_symtab is called.
2539 (dump_section_relocs): Note whether a symbol is a section symbol
2541 (adjust_reloc_syms): For now, always supply an absolute symbol for
2542 fixups without symbols but not yet `done'. Use section_symbol to
2543 get the symbol, instead of going directly for abs_symbol.
2544 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2545 reloc is not a section symbol and is not in the symbol table.
2546 (set_symtab): New function, broken out from write_object_file.
2547 Counts symbol table instead of relying on an earlier count.
2548 (write_object_file): Call set_symtab, but do it after potentially
2549 invoking the *_frob_file macros. Don't bother counting symbols.
2550 Call symbol_remove, instead of expanding it in place. Moved the
2551 conditionalized `object_file_size' declaration down to
2552 conditionalized block where it's used. When using the absolute
2553 symbol for a fixup without a symbol, set sy_used_in_reloc.
2554 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2555 the correct symbol for the absolute section.
2557 * subsegs.c (section_symbol): Use symbol_new instead of
2558 symbol_make, since we may want it to go into the symbol table.
2559 Make the new symbol have internal linkage. If
2560 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2561 symbol with the newly created GAS symbol.
2562 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2563 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2568 (in_signed_range): New function.
2570 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2571 (sparc_ip, label "immediate"): Reject constants for pcrel
2572 instructions only if the relocation type indicates a "call"
2573 instruction and the offset is within range of a "jmpl %g0". If
2574 it's not in range, use the absolute section symbol plus an offset.
2575 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2577 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2579 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2582 * configure.in: Eliminated all targets using obj-coff but not
2583 defining BFD_ASSEMBLER; I think all such targets that are
2584 supported will be matched by real CPU-OS combinations earlier in
2586 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2587 some comments about the dpx2 configuration, but left it disabled,
2588 since it couldn't be reached before.
2589 (target a29k-amd-ebmonold): Deleted.
2591 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2599 the 'j' operand if there are no further alternatives for this
2602 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2603 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2604 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2606 * config/tc-mips.c (mips_align): Take new argument, label, and use
2607 it instead of global insn_label.
2608 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2609 call to mips_emit_delay and pass it to mips_align.
2611 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2613 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2615 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2616 argument to a .callinfo directive. Don't loop forever on errors.
2618 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2619 use pre-defined registers as arguments.

2623 * write.c (write_object_file): Check both S_IS_LOCAL and
2624 S_IS_EXTERNAL when deciding whether to discard a symbol.
2626 * config-gas.com: Scan Makefile.in, not version.c, for current
2627 version number. Delete all versions of temp files when finished
2628 with them. Create config.h.
2630 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2631 values to reduce number of lookups with S_GET_VALUE. Skip debug
2632 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2633 holger@botbso.rhein-main.de.)
2634 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2635 field. (Also from Holger Teutsch.) Watch for a would-be register
2636 mask that spans frags.
2638 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2639 this_base, not line_base. (Patch from Andreas Arens,
2640 ari@obelix.av.rwth-aachen.de.)
2642 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2643 look local if they're exported or undefined. Used to be done for
2646 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2647 Get it from the looked-up symbol, instead of using the string from
2648 the input stream, which is no longer null-terminated.
2649 (LEX_PCT): New macro, defaults to 0.
2650 (lex_type): Use it for `%'.
2652 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2653 (vip_op): Now static, and returns void. Callers changed. Added

2702 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2703 0xffff for 'j' to be compatible with MIPS assembler. These

4777 default is to assume production environment, and reject configs
4778 still being worked on. Mark Elf configurations (except sparc and
4779 i386) as developmental. Deleted cases matching some generic names
4780 in favor of more specific names. (E.g., when we get Alpha

4799 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4800 conditional code in a few small places.
4802 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4803 structures, global variables, forward declarations together.

4806 into a few places. Make all functions and variables which
4807 are only used within tc-hppa.c static. PARAMize all functions.
4808 Add comments to functions. Delete unused functions, variables,
4809 #defines, etc. Delete unused members within structures. Delete
4810 ldil;ble hacks -- it is believed they were installed to work
4811 around old gas bugs. Avoid using mixed case for local
4812 functions, variables, and structures. Fix formatting problems
4813 not found by GNU-indent. Add FIXME notices for things which
4814 should be worked on the near future. Delete lots of old
4815 useless (1.36 PA-SOM) code.

4832 * config/tc-hppa.c: Likewise.
4834 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4835 of elf32_symbol_type.
4836 (pa_export_args): Likewise.

4844 a multiple of the section alignment rather than always a
4847 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4848 bits are zero (eg they specify no relocations), then do not even
4849 bother adding their entries to thesymextn section.

4894 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4896 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4897 ELF, since the ELF object format does not have these type of
4898 relocations. Change the abort into as as_bad and return
4899 BFD_RELOC_NONE to silence compiler warnings.
4900 (md_assemble): Keep track of the instruction size. Allow white

7346 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7386 dropping a space immediately following an identifier.

7388 lines; I don't think that can be done portably.
7389 * config/tc-mips.c (macro): Use $AT if target register is zero in

7514 * make-gas.com: Find obstack.obj if it's not in the current
7516 * read.c (s_ignore): Don't declare is_end_of_line. It's
7517 redundant, and triggers a VMS gcc compiler bug.
7519 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7520 current segment as an argument. (Ignored in all cases but VMS.)
7521 All callers and definitions changed.

7537 (obj_elf_xstab): New routine.
7538 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
7539 argument to s_ignore. Put "#if 0" around unused code.
7540 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
7541 Call elf_xstabs for .stabs and .xstabs operators.
7543 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7545 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7548 * configure.in: mips-bsd configuration was missing format spec.
7551 * Makefile.in (Makefile): Depends on configure.in.

7574 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7575 constants are accepted, but symbolic values are not. GCC will not
7576 generate the latter currently.
7578 * frags.c (frag_init): New function.
7579 (zero_address_frag, bss_address_frag): Now initialized at run
7581 * as.c (main): Call frag_init.

7852 (operand): Treat zero byte as end-of-operand.
7854 * configure.in (per-target): Look for with_bfd_assembler option.
7855 For now, only accept "no", until the merge is done.
7857 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7858 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7859 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7860 * read.c: Finish conversion to S_* macros in the VMS only

7864 * expr.c: Add "const" modifier to hex_value.
7865 * symbols.c: Finish conversion to S_* macros in the VMS only
7866 parts of the program. Add "const" modifier to
7867 md_[long,short]_jump_size. Remove declaration of const_flag
7868 (which will be declared in obj-vms.h).
7869 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7870 Fix arguments to VMS_write_object_file.
7871 * config-gas.com: New file. Script for VMS systems to set up the

7880 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7881 types of malformed stabs. Change parsing algorithm so that we are
7882 more certain of having all of the information that we need on hand.

7931 mapping to segT enum values.
7932 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7933 if these are used or defined, if BFD_ASSEMBLER.
7934 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7935 subseg_new split into two functions.
7936 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7938 * as.h (volatile): Don't define if already defined.
7939 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7950 <mtranle@paris.intellicorp.com>.
7951 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use

7955 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7957 (LDFLAGS): Added, defined as -shlib.
7958 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7959 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7960 (DOT_LABEL_PREFIX): Define.
7961 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7962 name rather than L0\001.
7963 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7965 * symbols.c, symbols.h (local_bss_counter): Removed.
7966 * write.c (write_object_file): bss no longer uses
7967 local_bss_counter. Pass correct data and bss size to
7968 VMS_write_object_file.

7974 (size_section): Restored sanity check.
7975 (do_relocs_for): Base section address on s_paddr rather than
7976 computing it. Adjust a29k R_IHIHALF special case to account for
7977 section paddr (used to require paddr to be zero). If there are no
7978 reclos, set s_relptr to 0. Set relocation size in object_headers.
7979 (fill_section): Always set s_vaddr here, removing
7980 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7981 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7982 Set STYP_INFO for .comment.
7983 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7984 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7987 (do_linenos_for): Set lineno size in object_headers.
7988 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7989 set s_vaddr here. If string_byte_count remains 4, set it back to
7990 0, and only write strings out if there are some. Call
7991 fill_section before do_relocs_for and do_linenos_for.
7992 (obj_coff_section): Handle optional quoted second argument giving
7993 section characteristics.
7994 (obj_coff_bss): Added to handle .bss.
7995 (obj_coff_ident): Added to handle .ident (puts string in .comment
7997 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7998 (fixup_mdeps): Change to segment. Call frag_wane after
8000 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8001 adjustment (already happened only for common symbols, but this is
8003 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8004 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8015 (do_scrub_next_char): For \", return " not '.
8016 (symbol_chars): Now const.
8018 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8019 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8021 * config/obj-coff.h: Don't use #elif.
8023 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8024 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8051 using ZERO_BASED_SEGMENTS.
8052 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8053 never set segment address for SEG_E2 (.bss) and don't write out
8054 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8055 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8056 definitions, and don't merge tags with non-tags. Check for .bf
8057 rather than just checking whether the second character is b and
8058 the third character is f.
8059 (obj_coff_val): gcc can generate values which we don't handle
8060 correctly; discard information for now, since it only affects the
8061 debugging information.

8063 (yank_symbols): Don't merge labels.
8064 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8209 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8210 could be doing emulation.
8212 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8215 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8244 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8246 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8247 constant will not fit in an immediate field.
8248 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8283 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8285 * Support for i386-sysv.
8286 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8310 * tc-m68k.c (get_num): make it work for all segments, not just the
8313 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8315 * configure.in: recognize i386-*-bsd emulation.

8324 * tc-z8k.c: lots of bug fixes
8326 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8328 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8329 #elif, since it is not supported by old compilers.
8330 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8331 couple of expressions in tc-m68k.c.
8333 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8335 * read.c (cons): If NO_RELOC is defined, use it.
8337 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8339 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8341 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8342 local labels to start with a .) and set REGISTER_PREFIX to %.
8343 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8345 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8347 * messages.c: Comment changes.
8349 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8352 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8354 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8356 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8359 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8361 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8362 sections starting from zero, rather than making them consecutive.
8363 This makes subsequent reloc calculations easier, esp if the object
8364 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8365 allocate lcomm in .data rather than in .bss. It seems that some
8366 tools can't cope with a non-zero sized bss before linkage.
8368 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8370 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8371 throughout. That enum no longer means what we thought it meant.
8373 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8374 "-mno-688[58]1" options.
8376 * tc-m68k.c: Added CPU32 support.

8384 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8385 Change LIBDEPS dependence to LIBS.
8387 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8389 * Makefile.in (install): if $(tooldir) exists, install as in
8392 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8394 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8395 .word is < -32768 or > 32767. The -J flag causes the error to be
8396 ignored. This is to catch over-sized switches generated by gcc on
8397 systems which don't support the broken .word hack.
8398 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8399 write.c (fixup_segment): check for signed .word overflow if
8400 WARN_SIGNED_OVERFLOW_WORD.
8402 * write.c (fixup_segment): fixed missing parens in expression
8403 checking for byte or word overflow.
8405 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8406 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

8415 * obj-coffbfd.h : added stuff
8416 * tc-i386.c (tc_coff_fix2rtype): new function
8417 * tc-i386.h : new coff defines
8419 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8421 * input-scrub.c (input_scrub_push): call input_file_begin, not
8423 messages.c (as_perror): print ": " between the passed in error and
8424 the strerror, like perror does.
8426 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8428 * Makefile.in: use gas_target instead of modifying target_cpu.
8429 From Steve Chamberlain:
8430 Makefile.in: Handle m68*-*-coff*.
8431 read.c, read.h: add mult argument to s_space
8433 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8434 Motorola and MIT syntax; gas can now assemble either type of
8436 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
8437 From Steve Chamberlain:
8438 m68kcoff.mt: for m68k COFF.

8516 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8517 written with indirection on the last two operands, which can be
8518 either data or address registers. Added a new operand type 'r'
8519 which accepts either register type. Added '(' to notend stuff in
8520 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8769 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8771 * Makefile.in (install): Install into $(tooldir)/bin, since that's

8859 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8861 * expr.c: If an expression is single comma, then return with
8862 SEG_ABSENT rather than an error - since the sparc front end does
8863 really strange things with things like fbge,a
8865 * as.h: include bfd.h if using many sections
8866 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8867 local labels didn't work.
8868 * listing.c (list_symbol_table): don't core dump when there's no
8870 * write.c, write.h: call fix_new with the right number of args on
8872 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8875 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8877 * app.c: MRI compatibility - allow single quote to start a string.
8878 * as.c: fix typo recently introduced.
8879 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8880 * expr.c: Much rewriting, to accomodate MRI syntax for
8881 expressions. Also easier to read now.
8882 * listing.c: Put back defuns
8883 * read.c: modified to accept MRI syntax, put back listing pseudo
8884 ops so that an assembler built with NO_LISTING ignores list ops
8886 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8887 machine is a SPARC or a 29K.
8888 * config/obj-aout.c: added s_sect pseudo op
8889 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8890 fill in the timestamp.
8891 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8892 anymore, define all the relocs which the tc-<x> bit will use so we
8893 can translate from them to the coff types.
8894 * config/tc-a29k.c: reloc_type isn't ane enum any more
8895 * config/tc-m68k.c: Added NO_RELOC definition.
8897 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8899 * Makefile.in: put header files before C source for TAGS; remove
8900 references to non-existent syscalls.h.
8902 * read.c, write.c subsegs.c: back out the .bss changes.
8904 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.

8910 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8912 * symbols.c (local_label_name): symbols now start with ^A.
8914 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8915 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8916 generate these sections. .align: will use NOP_OPCODE or 0
8917 for padding. This is just for being nice to the
8920 * expr.c (operand): changed to generate local label "\001L0"
8921 starting with a ^A so that it is recognized as a local label.
8923 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8925 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8926 i/o opcodes - inb, inw, outb and outw. string manipulation with
8927 att syntax - scmp, slod, smov, ssca, ssto.
8929 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8930 to just after .file .
8932 In obj_crawl_symbol_chain() where it tries to put the external
8933 symbols apart, with the condition:
8934 (!S_IS_DEFINED(symbolP) &&
8935 !S_IS_DEBUG(symbolP) &&
8936 !SF_GET_STATICS(symbolP))
8937 it was moving too many symbols out. So I switch it back to the
8939 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8941 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8942 so that we don't use the F_RELFLG which make the linker complain
8943 that somebody has stripped the relocation info.
8945 Also, the AIX ld program require that the relocation table
8946 is sorted by r_vaddr like the standard ATT assembler does.
8948 [he also changed the sizeof(struct ...)'s into the coff
8949 style FOOSZ macros. I'm not sure this is right, but I can't
8950 remember why. xoxorich.]

8954 * Makefile.in, configure.in, doc: use the doc. Build it, install
8957 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8959 * read.c: white space and comments only.
8961 * configure.in: use the new atof-ns32.c for ns32k.
8963 * write.c: comment change only.
8965 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8966 aren't yet integrated.
8968 * tc-i860.[hc]: blew off the dust. Something must still be done
8969 about conflicting relocation types.
8971 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8974 * tc-i960.c, tc-sparc.c: white space and comments only.
8976 * tc-a29k.h: delete duplicate macro definition.
8978 * new file atof-ns32k.c copied from hack's last unreleased gas.
8980 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8982 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8985 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8986 ChangeLog's prior to this are sketchy at best. I have logs.
8987 They just aren't ChangeLogs.
