513 * Makefile.in (all): Depend on .gdbinit.
514 (.gdbinit): Rebuild from gdbinit.in by running config.status.
516 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".

529 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
532 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
533 processing if add_symbol is undefined or in expr_section.
534 (resolve_symbol_value, case O_add): For symbol plus
535 constant-valued symbol, convert to O_symbol and re-reduce.
536 (S_GET_VALUE): If symbol needs resolving, resolve it.
537 (indent_level): No longer static.
538 (print_symbol_value_1): Don't print frag address if it matches
539 zero_address_frag. Don't print "resolving" if already resolved.
540 Print segment name. Don't call print_expr_1 on an undefined
542 (print_expr_1): Fix whitespace before printing X_add_number.
544 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
545 not symbol_new, for symbols holding expression values.
546 * expr.h (make_expr_symbol): Move declaration here.
547 * write.c (fix_new_exp): Handle O_add by creating an
548 expression-valued symbol, and calling fix_new_exp recursively.
549 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
550 undefined symbol and a constant, fold the constant into the fixup,
551 and refer to the undefined symbol directly. Then process the
552 fixup again from scratch.
553 (write_object_file): Before calling adjust_reloc_syms, make a pass
554 through the symbol list trying to resolve values.
556 * write.c (print_fixup): New routine, for debugging.
557 (write_relocs): Call bfd_install_relocation. Deleted various
558 hacks for working around problems with bfd_perform_relocation.

566 * config/tc-mips.c: Include subsegs.h.
567 (md_apply_fix): If an unconditional b or bal overflows, and we are
568 not assembling PIC code, replace it with a j or jal.
570 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
571 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
573 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
575 * write.c (write_relocs): Add file name and line number to
576 as_fatal calls. Handle bfd_reloc_overflow case specifically when
577 RELOC_EXPANSION_POSSIBLE.
579 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
581 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
582 here. Use them for deciding which PRINTF*LIKE macro definitions
584 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
585 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
586 default definitions matching what we were doing before.
587 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
588 always use the varargs form if not using stdarg. It's safe to
589 always use vfprintf, because libiberty will provide it if the
590 native system doesn't. Also, always make format be const.
591 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
593 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

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

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

639 md_create_short_jump, md_create_long_jump.
640 (brtab_emit): Use data_section, not SEG_DATA.
642 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
644 * config/vms-conf.h: new file, manually derived from conf.in.
645 * config-gas.com: use it, and eliminate obsolete "host.h".
647 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
649 * config/tc-ppc.c (ppc_current_block): New static variable.

655 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
656 from the csect of the enclosing block.
658 * config/tc-mips.c (insns_since_cache_access): Remove.
659 (append_insn): Remove setting of insns_since_cache_access, and

662 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
664 * config/tc-mips.c (md_shortopts): Remove E.
665 (md_longopts): Add EB and EL.
666 (md_parse_option): Handle -EB and -EL as separate options, rather
667 than as a single -E option with an argument.
669 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
671 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
672 involving global symbols too.
674 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
676 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
678 * configure.in: Test for remove, not delete. Fix cross-assembler

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

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

835 Update for autoconf 1.118:
836 * gdbinit.in: New file, created from old .gdbinit.
838 * aclocal.m4 (GAS_GDBINIT): Deleted.
839 * configure.in: Don't use it. Instead, generate .gdbinit from
840 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
841 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
842 to ensure that older versions of autoconf aren't used.
843 * Makefile.in: Added @configure_input@ line.

934 * read.c (read_a_source_file): The second argument to as_where is
935 unsigned int *, not int *.

2379 targets, now explicitly checking $(srcdir) for info files.
2380 (install-info): Depend on both of them; do nothing more.

2388 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2389 flag rather than signedp field. Only permit extended range if
2390 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2391 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2393 * config/tc-ppc.c (ppc_size): New static variable.
2394 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2395 (md_begin): If an instruction has a size specific flag set, only
2396 add it if we are assembling that size.
2398 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2400 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2401 cross section PC relative relocs right for COFF and ELF.
2403 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2416 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2417 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2418 and -many (all architectures).
2420 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2429 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2431 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2432 branch with an instruction that uses $at, in case the branch is
2434 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2435 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2436 to make it pcrel_offset.
2437 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2438 reloc->address; another gruesome hack to get gas reloc handling to
2441 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2443 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2446 (emit_insn): New function.
2447 (md_assemble): Call it.
2448 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2450 (lituse_pending): New variable. Set by anything that generates a
2451 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2452 tested by code that might want to emit a LITUSE reloc.
2453 (emit_unaligned_io): New function. Currently calls md_assemble,
2454 but it should eventually be converted to generate the insn itself
2455 and call emit_insn directly.
2456 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2457 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2458 emit_bis_r): Likewise.

2467 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2469 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2470 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2471 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2473 (mips_force_relocation): New function.
2474 (md_apply_fix): Set fixP->fx_done appropriately.
2475 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2486 (load_address): Handle EMBEDDED_PIC.
2487 (macro): Handle EMBEDDED_PIC in all PIC cases.
2488 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2489 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2490 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2491 works). Do not permit -G with SVR4_PIC.
2492 (s_abicalls): Warn if -G was used, and force -G 0.
2493 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2494 anything but a.out, not just for ELF. For ECOFF, don't generate a
2495 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2497 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2499 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2501 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2502 parameters to avoid losing when compiling with HP CC.
2503 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2505 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2507 * Makefile.in (config-stamp): If `defs' is defined, emit a
2508 preprocessor directive to create a macro named by this value into
2509 config.new; don't explicitly go for BFD_ASSEMBLER.
2510 * configure.in: Define `defs', not `BFDDEF'. Set it to
2511 MANY_SEGMENTS for any obj-coffbfd target.
2512 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2513 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2515 (LOCAL_LOADLIBES): Deleted.
2516 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2517 * config/m88kcoff.mt (TDEFINES): Ditto.
2518 * config/ebmon29k.mt: Deleted.

2521 * config/sparc.mt: Deleted.
2522 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2543 bfd_set_symtab is called.
2544 (dump_section_relocs): Note whether a symbol is a section symbol
2546 (adjust_reloc_syms): For now, always supply an absolute symbol for
2547 fixups without symbols but not yet `done'. Use section_symbol to
2548 get the symbol, instead of going directly for abs_symbol.
2549 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2550 reloc is not a section symbol and is not in the symbol table.
2551 (set_symtab): New function, broken out from write_object_file.
2552 Counts symbol table instead of relying on an earlier count.
2553 (write_object_file): Call set_symtab, but do it after potentially
2554 invoking the *_frob_file macros. Don't bother counting symbols.
2555 Call symbol_remove, instead of expanding it in place. Moved the
2556 conditionalized `object_file_size' declaration down to
2557 conditionalized block where it's used. When using the absolute
2558 symbol for a fixup without a symbol, set sy_used_in_reloc.
2559 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2560 the correct symbol for the absolute section.
2562 * subsegs.c (section_symbol): Use symbol_new instead of
2563 symbol_make, since we may want it to go into the symbol table.
2564 Make the new symbol have internal linkage. If
2565 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2566 symbol with the newly created GAS symbol.
2567 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2568 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2573 (in_signed_range): New function.
2575 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2576 (sparc_ip, label "immediate"): Reject constants for pcrel
2577 instructions only if the relocation type indicates a "call"
2578 instruction and the offset is within range of a "jmpl %g0". If
2579 it's not in range, use the absolute section symbol plus an offset.
2580 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2582 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2584 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2587 * configure.in: Eliminated all targets using obj-coff but not
2588 defining BFD_ASSEMBLER; I think all such targets that are
2589 supported will be matched by real CPU-OS combinations earlier in
2591 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2592 some comments about the dpx2 configuration, but left it disabled,
2593 since it couldn't be reached before.
2594 (target a29k-amd-ebmonold): Deleted.
2596 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2604 the 'j' operand if there are no further alternatives for this
2607 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2608 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2609 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2611 * config/tc-mips.c (mips_align): Take new argument, label, and use
2612 it instead of global insn_label.
2613 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2614 call to mips_emit_delay and pass it to mips_align.
2616 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2618 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2620 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2621 argument to a .callinfo directive. Don't loop forever on errors.
2623 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2624 use pre-defined registers as arguments.

2628 * write.c (write_object_file): Check both S_IS_LOCAL and
2629 S_IS_EXTERNAL when deciding whether to discard a symbol.
2631 * config-gas.com: Scan Makefile.in, not version.c, for current
2632 version number. Delete all versions of temp files when finished
2633 with them. Create config.h.
2635 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2636 values to reduce number of lookups with S_GET_VALUE. Skip debug
2637 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2638 holger@botbso.rhein-main.de.)
2639 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2640 field. (Also from Holger Teutsch.) Watch for a would-be register
2641 mask that spans frags.
2643 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2644 this_base, not line_base. (Patch from Andreas Arens,
2645 ari@obelix.av.rwth-aachen.de.)
2647 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2648 look local if they're exported or undefined. Used to be done for
2651 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2652 Get it from the looked-up symbol, instead of using the string from
2653 the input stream, which is no longer null-terminated.
2654 (LEX_PCT): New macro, defaults to 0.
2655 (lex_type): Use it for `%'.
2657 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2707 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2708 0xffff for 'j' to be compatible with MIPS assembler. These

4782 default is to assume production environment, and reject configs
4783 still being worked on. Mark Elf configurations (except sparc and
4784 i386) as developmental. Deleted cases matching some generic names
4785 in favor of more specific names. (E.g., when we get Alpha

4812 are only used within tc-hppa.c static. PARAMize all functions.
4813 Add comments to functions. Delete unused functions, variables,
4814 #defines, etc. Delete unused members within structures. Delete
4815 ldil;ble hacks -- it is believed they were installed to work
4816 around old gas bugs. Avoid using mixed case for local
4817 functions, variables, and structures. Fix formatting problems
4818 not found by GNU-indent. Add FIXME notices for things which
4819 should be worked on the near future. Delete lots of old
4820 useless (1.36 PA-SOM) code.

4840 of elf32_symbol_type.
4841 (pa_export_args): Likewise.

4849 a multiple of the section alignment rather than always a
4852 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

4899 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4901 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4902 ELF, since the ELF object format does not have these type of
4903 relocations. Change the abort into as as_bad and return
4904 BFD_RELOC_NONE to silence compiler warnings.
4905 (md_assemble): Keep track of the instruction size. Allow white
4906 space between the $ and the constant for compatibility with older

7351 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7391 dropping a space immediately following an identifier.

7393 lines; I don't think that can be done portably.
7394 * config/tc-mips.c (macro): Use $AT if target register is zero in

7519 * make-gas.com: Find obstack.obj if it's not in the current
7521 * read.c (s_ignore): Don't declare is_end_of_line. It's
7522 redundant, and triggers a VMS gcc compiler bug.
7524 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7525 current segment as an argument. (Ignored in all cases but VMS.)
7526 All callers and definitions changed.

7542 (obj_elf_xstab): New routine.
7543 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
7544 argument to s_ignore. Put "#if 0" around unused code.

7579 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7580 constants are accepted, but symbolic values are not. GCC will not
7581 generate the latter currently.
7583 * frags.c (frag_init): New function.
7584 (zero_address_frag, bss_address_frag): Now initialized at run
7586 * as.c (main): Call frag_init.

7857 (operand): Treat zero byte as end-of-operand.
7859 * configure.in (per-target): Look for with_bfd_assembler option.
7860 For now, only accept "no", until the merge is done.
7862 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7863 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7869 * expr.c: Add "const" modifier to hex_value.
7870 * symbols.c: Finish conversion to S_* macros in the VMS only

7872 md_[long,short]_jump_size. Remove declaration of const_flag
7873 (which will be declared in obj-vms.h).
7874 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7875 Fix arguments to VMS_write_object_file.
7876 * config-gas.com: New file. Script for VMS systems to set up the

7936 mapping to segT enum values.
7937 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7938 if these are used or defined, if BFD_ASSEMBLER.
7939 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7940 subseg_new split into two functions.
7941 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7943 * as.h (volatile): Don't define if already defined.
7944 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7959 * config/i386aix.mt: Removed (no longer used).
7960 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7962 (LDFLAGS): Added, defined as -shlib.
7963 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7964 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7965 (DOT_LABEL_PREFIX): Define.
7966 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7967 name rather than L0\001.
7968 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7970 * symbols.c, symbols.h (local_bss_counter): Removed.
7971 * write.c (write_object_file): bss no longer uses
7972 local_bss_counter. Pass correct data and bss size to
7973 VMS_write_object_file.

7979 (size_section): Restored sanity check.
7980 (do_relocs_for): Base section address on s_paddr rather than
7981 computing it. Adjust a29k R_IHIHALF special case to account for
7982 section paddr (used to require paddr to be zero). If there are no
7983 reclos, set s_relptr to 0. Set relocation size in object_headers.
7984 (fill_section): Always set s_vaddr here, removing
7985 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7986 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7987 Set STYP_INFO for .comment.

7992 (do_linenos_for): Set lineno size in object_headers.
7993 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7994 set s_vaddr here. If string_byte_count remains 4, set it back to
7995 0, and only write strings out if there are some. Call
7996 fill_section before do_relocs_for and do_linenos_for.
7997 (obj_coff_section): Handle optional quoted second argument giving
7998 section characteristics.
7999 (obj_coff_bss): Added to handle .bss.
8000 (obj_coff_ident): Added to handle .ident (puts string in .comment
8002 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8003 (fixup_mdeps): Change to segment. Call frag_wane after
8005 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8006 adjustment (already happened only for common symbols, but this is
8008 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8009 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8020 (do_scrub_next_char): For \", return " not '.
8021 (symbol_chars): Now const.
8023 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8024 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8026 * config/obj-coff.h: Don't use #elif.
8028 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8029 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8056 using ZERO_BASED_SEGMENTS.
8057 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8058 never set segment address for SEG_E2 (.bss) and don't write out
8059 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8060 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8061 definitions, and don't merge tags with non-tags. Check for .bf
8062 rather than just checking whether the second character is b and
8063 the third character is f.
8064 (obj_coff_val): gcc can generate values which we don't handle
8065 correctly; discard information for now, since it only affects the
8066 debugging information.

8068 (yank_symbols): Don't merge labels.
8069 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8215 could be doing emulation.
8217 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8220 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8249 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8251 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8252 constant will not fit in an immediate field.
8253 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8288 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8290 * Support for i386-sysv.
8291 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8315 * tc-m68k.c (get_num): make it work for all segments, not just the
8318 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8320 * configure.in: recognize i386-*-bsd emulation.

8329 * tc-z8k.c: lots of bug fixes
8331 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8333 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8334 #elif, since it is not supported by old compilers.
8335 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8336 couple of expressions in tc-m68k.c.
8338 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8340 * read.c (cons): If NO_RELOC is defined, use it.
8342 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8344 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8346 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8347 local labels to start with a .) and set REGISTER_PREFIX to %.
8348 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8350 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8357 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8359 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8361 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8364 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8366 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8367 sections starting from zero, rather than making them consecutive.
8368 This makes subsequent reloc calculations easier, esp if the object
8369 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8370 allocate lcomm in .data rather than in .bss. It seems that some
8371 tools can't cope with a non-zero sized bss before linkage.
8373 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8375 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8376 throughout. That enum no longer means what we thought it meant.
8378 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8379 "-mno-688[58]1" options.
8381 * tc-m68k.c: Added CPU32 support.

8389 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8390 Change LIBDEPS dependence to LIBS.
8392 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8394 * Makefile.in (install): if $(tooldir) exists, install as in
8397 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8399 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8400 .word is < -32768 or > 32767. The -J flag causes the error to be
8401 ignored. This is to catch over-sized switches generated by gcc on
8402 systems which don't support the broken .word hack.
8403 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8404 write.c (fixup_segment): check for signed .word overflow if
8405 WARN_SIGNED_OVERFLOW_WORD.
8407 * write.c (fixup_segment): fixed missing parens in expression
8408 checking for byte or word overflow.
8410 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8411 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

8422 * tc-i386.h : new coff defines
8424 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8426 * input-scrub.c (input_scrub_push): call input_file_begin, not
8428 messages.c (as_perror): print ": " between the passed in error and
8429 the strerror, like perror does.
8431 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8433 * Makefile.in: use gas_target instead of modifying target_cpu.
8434 From Steve Chamberlain:
8435 Makefile.in: Handle m68*-*-coff*.
8436 read.c, read.h: add mult argument to s_space
8438 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8439 Motorola and MIT syntax; gas can now assemble either type of
8441 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
8442 From Steve Chamberlain:

8521 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8522 written with indirection on the last two operands, which can be
8523 either data or address registers. Added a new operand type 'r'
8524 which accepts either register type. Added '(' to notend stuff in
8525 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8774 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8776 * Makefile.in (install): Install into $(tooldir)/bin, since that's

8864 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8866 * expr.c: If an expression is single comma, then return with
8867 SEG_ABSENT rather than an error - since the sparc front end does
8868 really strange things with things like fbge,a
8870 * as.h: include bfd.h if using many sections
8871 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8872 local labels didn't work.
8873 * listing.c (list_symbol_table): don't core dump when there's no
8875 * write.c, write.h: call fix_new with the right number of args on

8880 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8882 * app.c: MRI compatibility - allow single quote to start a string.
8883 * as.c: fix typo recently introduced.
8884 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8885 * expr.c: Much rewriting, to accomodate MRI syntax for
8886 expressions. Also easier to read now.
8887 * listing.c: Put back defuns
8888 * read.c: modified to accept MRI syntax, put back listing pseudo
8889 ops so that an assembler built with NO_LISTING ignores list ops
8891 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8892 machine is a SPARC or a 29K.
8893 * config/obj-aout.c: added s_sect pseudo op
8894 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8895 fill in the timestamp.
8896 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8897 anymore, define all the relocs which the tc-<x> bit will use so we
8898 can translate from them to the coff types.
8899 * config/tc-a29k.c: reloc_type isn't ane enum any more
8900 * config/tc-m68k.c: Added NO_RELOC definition.
8902 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8904 * Makefile.in: put header files before C source for TAGS; remove
8905 references to non-existent syscalls.h.
8907 * read.c, write.c subsegs.c: back out the .bss changes.
8909 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.

8915 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8917 * symbols.c (local_label_name): symbols now start with ^A.
8919 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8920 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8921 generate these sections. .align: will use NOP_OPCODE or 0
8922 for padding. This is just for being nice to the
8925 * expr.c (operand): changed to generate local label "\001L0"
8926 starting with a ^A so that it is recognized as a local label.
8928 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8930 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8931 i/o opcodes - inb, inw, outb and outw. string manipulation with
8932 att syntax - scmp, slod, smov, ssca, ssto.
8934 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8935 to just after .file .
8937 In obj_crawl_symbol_chain() where it tries to put the external
8938 symbols apart, with the condition:
8939 (!S_IS_DEFINED(symbolP) &&
8940 !S_IS_DEBUG(symbolP) &&
8941 !SF_GET_STATICS(symbolP))
8942 it was moving too many symbols out. So I switch it back to the
8944 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8946 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8947 so that we don't use the F_RELFLG which make the linker complain
8948 that somebody has stripped the relocation info.
8950 Also, the AIX ld program require that the relocation table
8951 is sorted by r_vaddr like the standard ATT assembler does.
8953 [he also changed the sizeof(struct ...)'s into the coff
8954 style FOOSZ macros. I'm not sure this is right, but I can't
8955 remember why. xoxorich.]

8959 * Makefile.in, configure.in, doc: use the doc. Build it, install
8962 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8964 * read.c: white space and comments only.
8966 * configure.in: use the new atof-ns32.c for ns32k.
8968 * write.c: comment change only.
8970 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8971 aren't yet integrated.
8973 * tc-i860.[hc]: blew off the dust. Something must still be done
8974 about conflicting relocation types.
8976 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8979 * tc-i960.c, tc-sparc.c: white space and comments only.
8981 * tc-a29k.h: delete duplicate macro definition.
8983 * new file atof-ns32k.c copied from hack's last unreleased gas.

8987 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8990 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8991 ChangeLog's prior to this are sketchy at best. I have logs.
8992 They just aren't ChangeLogs.
