514 includes the frag address.
515 (fixup_segment): Changed local var PCREL to type int, added PLT.
516 If PC-relative fixup refers to a PLT entry for a symbol in the
517 current section, don't reduce it.

520 DEBUG5 is defined, print out each fixup before and after
522 (fixup_segment): If DEBUG5 is defined, print out each fixup before
523 and after processing.
524 (print_fixup): Added prototype. Show address on first line. Show
525 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
526 NEED_FX_R_TYPE is defined.

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

557 (indent_level): No longer static.
558 (print_symbol_value_1): Don't print frag address if it matches
559 zero_address_frag. Don't print "resolving" if already resolved.
560 Print segment name. Don't call print_expr_1 on an undefined
562 (print_expr_1): Fix whitespace before printing X_add_number.
564 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
565 not symbol_new, for symbols holding expression values.
566 * expr.h (make_expr_symbol): Move declaration here.
567 * write.c (fix_new_exp): Handle O_add by creating an
568 expression-valued symbol, and calling fix_new_exp recursively.
569 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
570 undefined symbol and a constant, fold the constant into the fixup,
571 and refer to the undefined symbol directly. Then process the
572 fixup again from scratch.
573 (write_object_file): Before calling adjust_reloc_syms, make a pass
574 through the symbol list trying to resolve values.
576 * write.c (print_fixup): New routine, for debugging.
577 (write_relocs): Call bfd_install_relocation. Deleted various
578 hacks for working around problems with bfd_perform_relocation.

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

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

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

646 * symbols.c (copy_symbol_attributes): New function. Copies BFD
647 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
648 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
649 zero. Don't call obj_frob_forward_symbol.

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

674 (ppc_es): Clear ppc_current_block.
675 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
676 from the csect of the enclosing block.
678 * config/tc-mips.c (insns_since_cache_access): Remove.
679 (append_insn): Remove setting of insns_since_cache_access, and

682 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
684 * config/tc-mips.c (md_shortopts): Remove E.
685 (md_longopts): Add EB and EL.
686 (md_parse_option): Handle -EB and -EL as separate options, rather
687 than as a single -E option with an argument.
689 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
691 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
692 involving global symbols too.
694 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
696 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
698 * configure.in: Test for remove, not delete. Fix cross-assembler

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

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

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

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

855 Update for autoconf 1.118:
856 * gdbinit.in: New file, created from old .gdbinit.
858 * aclocal.m4 (GAS_GDBINIT): Deleted.
859 * configure.in: Don't use it. Instead, generate .gdbinit from
860 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
861 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
862 to ensure that older versions of autoconf aren't used.

1928 VMS debugger now recognizes `long long' variables correctly.
1929 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1930 for gcc2's predefined types "long double" (same as double, as
1931 per gcc's current state), "long long int", "long long unsigned
1932 int", and final `otherwise' case (to avoid uninitialized type
1933 and size fields). [caveat: predefined types "complex int",
1934 "complex float", "complex double", and "complex long double" are
1937 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1938 of 0, because the latter indicates success rather than failure

1942 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.

2302 source files from other directories into objects in the current
2303 directory, and specify PSECT attributes explicitly to linker.
2304 Also added missing label.
2305 * Makefile.in (stamp-mk.com): Reference new variable

2393 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2394 don't spew remainder of input file in error message.
2395 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2396 message with reloc type and try to process remainder of file.

2399 targets, now explicitly checking $(srcdir) for info files.
2400 (install-info): Depend on both of them; do nothing more.

2408 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2409 flag rather than signedp field. Only permit extended range if
2410 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.

2413 * config/tc-ppc.c (ppc_size): New static variable.
2414 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2415 (md_begin): If an instruction has a size specific flag set, only
2416 add it if we are assembling that size.

2420 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2421 cross section PC relative relocs right for COFF and ELF.
2423 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2449 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2451 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2452 branch with an instruction that uses $at, in case the branch is
2454 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

2456 to make it pcrel_offset.
2457 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2458 reloc->address; another gruesome hack to get gas reloc handling to

2463 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2466 (emit_insn): New function.
2467 (md_assemble): Call it.
2468 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2470 (lituse_pending): New variable. Set by anything that generates a
2471 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2472 tested by code that might want to emit a LITUSE reloc.
2473 (emit_unaligned_io): New function. Currently calls md_assemble,
2474 but it should eventually be converted to generate the insn itself
2475 and call emit_insn directly.
2476 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2477 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2478 emit_bis_r): Likewise.

2489 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2490 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2491 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2506 (load_address): Handle EMBEDDED_PIC.
2507 (macro): Handle EMBEDDED_PIC in all PIC cases.
2508 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2509 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2510 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2511 works). Do not permit -G with SVR4_PIC.
2512 (s_abicalls): Warn if -G was used, and force -G 0.
2513 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2514 anything but a.out, not just for ELF. For ECOFF, don't generate a
2515 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2517 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2519 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2525 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2527 * Makefile.in (config-stamp): If `defs' is defined, emit a
2528 preprocessor directive to create a macro named by this value into
2529 config.new; don't explicitly go for BFD_ASSEMBLER.
2530 * configure.in: Define `defs', not `BFDDEF'. Set it to
2531 MANY_SEGMENTS for any obj-coffbfd target.
2532 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2533 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

2563 bfd_set_symtab is called.
2564 (dump_section_relocs): Note whether a symbol is a section symbol
2566 (adjust_reloc_syms): For now, always supply an absolute symbol for
2567 fixups without symbols but not yet `done'. Use section_symbol to
2568 get the symbol, instead of going directly for abs_symbol.
2569 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2570 reloc is not a section symbol and is not in the symbol table.
2571 (set_symtab): New function, broken out from write_object_file.
2572 Counts symbol table instead of relying on an earlier count.
2573 (write_object_file): Call set_symtab, but do it after potentially
2574 invoking the *_frob_file macros. Don't bother counting symbols.
2575 Call symbol_remove, instead of expanding it in place. Moved the
2576 conditionalized `object_file_size' declaration down to
2577 conditionalized block where it's used. When using the absolute
2578 symbol for a fixup without a symbol, set sy_used_in_reloc.
2579 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2580 the correct symbol for the absolute section.
2582 * subsegs.c (section_symbol): Use symbol_new instead of
2583 symbol_make, since we may want it to go into the symbol table.
2584 Make the new symbol have internal linkage. If
2585 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2586 symbol with the newly created GAS symbol.
2587 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2588 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2593 (in_signed_range): New function.
2595 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2596 (sparc_ip, label "immediate"): Reject constants for pcrel
2597 instructions only if the relocation type indicates a "call"
2598 instruction and the offset is within range of a "jmpl %g0". If
2599 it's not in range, use the absolute section symbol plus an offset.
2600 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2602 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2604 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2607 * configure.in: Eliminated all targets using obj-coff but not
2608 defining BFD_ASSEMBLER; I think all such targets that are
2609 supported will be matched by real CPU-OS combinations earlier in
2611 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2612 some comments about the dpx2 configuration, but left it disabled,
2613 since it couldn't be reached before.
2614 (target a29k-amd-ebmonold): Deleted.
2616 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2624 the 'j' operand if there are no further alternatives for this
2627 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2628 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2629 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2631 * config/tc-mips.c (mips_align): Take new argument, label, and use
2632 it instead of global insn_label.
2633 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2634 call to mips_emit_delay and pass it to mips_align.
2636 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2638 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2640 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2641 argument to a .callinfo directive. Don't loop forever on errors.
2643 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2644 use pre-defined registers as arguments.

2648 * write.c (write_object_file): Check both S_IS_LOCAL and
2649 S_IS_EXTERNAL when deciding whether to discard a symbol.
2651 * config-gas.com: Scan Makefile.in, not version.c, for current
2652 version number. Delete all versions of temp files when finished
2653 with them. Create config.h.
2655 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2656 values to reduce number of lookups with S_GET_VALUE. Skip debug
2657 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2658 holger@botbso.rhein-main.de.)
2659 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2660 field. (Also from Holger Teutsch.) Watch for a would-be register
2661 mask that spans frags.
2663 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2664 this_base, not line_base. (Patch from Andreas Arens,
2665 ari@obelix.av.rwth-aachen.de.)
2667 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2668 look local if they're exported or undefined. Used to be done for
2671 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2672 Get it from the looked-up symbol, instead of using the string from
2673 the input stream, which is no longer null-terminated.
2674 (LEX_PCT): New macro, defaults to 0.
2675 (lex_type): Use it for `%'.
2677 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2678 (vip_op): Now static, and returns void. Callers changed. Added

2727 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2728 0xffff for 'j' to be compatible with MIPS assembler. These

4802 default is to assume production environment, and reject configs
4803 still being worked on. Mark Elf configurations (except sparc and
4804 i386) as developmental. Deleted cases matching some generic names
4805 in favor of more specific names. (E.g., when we get Alpha

4832 are only used within tc-hppa.c static. PARAMize all functions.
4833 Add comments to functions. Delete unused functions, variables,
4834 #defines, etc. Delete unused members within structures. Delete
4835 ldil;ble hacks -- it is believed they were installed to work
4836 around old gas bugs. Avoid using mixed case for local
4837 functions, variables, and structures. Fix formatting problems
4838 not found by GNU-indent. Add FIXME notices for things which
4839 should be worked on the near future. Delete lots of old
4840 useless (1.36 PA-SOM) code.

4860 of elf32_symbol_type.
4861 (pa_export_args): Likewise.

4869 a multiple of the section alignment rather than always a
4872 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

4919 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4921 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4922 ELF, since the ELF object format does not have these type of
4923 relocations. Change the abort into as as_bad and return
4924 BFD_RELOC_NONE to silence compiler warnings.
4925 (md_assemble): Keep track of the instruction size. Allow white
4926 space between the $ and the constant for compatibility with older
4927 gases and other assemblers.

7371 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7378 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

7411 dropping a space immediately following an identifier.

7413 lines; I don't think that can be done portably.
7414 * config/tc-mips.c (macro): Use $AT if target register is zero in

7489 prototypes for all static functions. Moved existing minimal
7490 debugging format support info #ifndef OBJ_ECOFF blocks.

7539 * make-gas.com: Find obstack.obj if it's not in the current
7541 * read.c (s_ignore): Don't declare is_end_of_line. It's
7542 redundant, and triggers a VMS gcc compiler bug.
7544 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7545 current segment as an argument. (Ignored in all cases but VMS.)
7546 All callers and definitions changed.

7570 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7573 * configure.in: mips-bsd configuration was missing format spec.
7576 * Makefile.in (Makefile): Depends on configure.in.
7578 * config/tc-mips.c (append_insn): Don't check for alignment of
7579 frag in memory; alignment of instructions in section is a separate

7599 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7600 constants are accepted, but symbolic values are not. GCC will not
7601 generate the latter currently.
7603 * frags.c (frag_init): New function.
7604 (zero_address_frag, bss_address_frag): Now initialized at run
7606 * as.c (main): Call frag_init.

7877 (operand): Treat zero byte as end-of-operand.
7879 * configure.in (per-target): Look for with_bfd_assembler option.
7880 For now, only accept "no", until the merge is done.
7882 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7883 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7884 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7885 * read.c: Finish conversion to S_* macros in the VMS only
7886 parts of the program. Add "const" modifier to hex_value.
7887 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7889 * expr.c: Add "const" modifier to hex_value.
7890 * symbols.c: Finish conversion to S_* macros in the VMS only
7891 parts of the program. Add "const" modifier to
7892 md_[long,short]_jump_size. Remove declaration of const_flag
7893 (which will be declared in obj-vms.h).
7894 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7895 Fix arguments to VMS_write_object_file.
7896 * config-gas.com: New file. Script for VMS systems to set up the
7897 configuration to build gas for VMS, and create config.status.

7913 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7914 as symbols as well in the object file. Look for external functions

7956 mapping to segT enum values.
7957 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7958 if these are used or defined, if BFD_ASSEMBLER.
7959 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7960 subseg_new split into two functions.

7963 * as.h (volatile): Don't define if already defined.
7964 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7966 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7967 declare with format attribute for -Wformat checking.
7969 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7971 * app.c, config/tc-*.c: Don't include read.h, since it is already
7974 * These are based on patches from Minh Tran-le
7975 <mtranle@paris.intellicorp.com>.
7976 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7977 obj_format coffbfd and gas_target i386coff for target.
7978 (i[34]86-*-isc*): New host (uses sysv).
7979 * config/i386aix.mt: Removed (no longer used).
7980 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7982 (LDFLAGS): Added, defined as -shlib.
7983 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7984 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7985 (DOT_LABEL_PREFIX): Define.
7986 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7987 name rather than L0\001.
7988 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7990 * symbols.c, symbols.h (local_bss_counter): Removed.
7991 * write.c (write_object_file): bss no longer uses
7992 local_bss_counter. Pass correct data and bss size to
7993 VMS_write_object_file.

7999 (size_section): Restored sanity check.
8000 (do_relocs_for): Base section address on s_paddr rather than
8001 computing it. Adjust a29k R_IHIHALF special case to account for
8002 section paddr (used to require paddr to be zero). If there are no
8003 reclos, set s_relptr to 0. Set relocation size in object_headers.
8004 (fill_section): Always set s_vaddr here, removing
8005 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8006 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8007 Set STYP_INFO for .comment.
8008 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8009 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8011 H_{SET,GET}_* macros.
8012 (do_linenos_for): Set lineno size in object_headers.
8013 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8014 set s_vaddr here. If string_byte_count remains 4, set it back to
8015 0, and only write strings out if there are some. Call
8016 fill_section before do_relocs_for and do_linenos_for.
8017 (obj_coff_section): Handle optional quoted second argument giving
8018 section characteristics.
8019 (obj_coff_bss): Added to handle .bss.
8020 (obj_coff_ident): Added to handle .ident (puts string in .comment
8022 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8023 (fixup_mdeps): Change to segment. Call frag_wane after
8025 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8026 adjustment (already happened only for common symbols, but this is
8028 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8029 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8040 (do_scrub_next_char): For \", return " not '.
8041 (symbol_chars): Now const.
8043 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8044 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8046 * config/obj-coff.h: Don't use #elif.
8048 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8049 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8051 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8076 using ZERO_BASED_SEGMENTS.
8077 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8078 never set segment address for SEG_E2 (.bss) and don't write out
8079 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8080 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8081 definitions, and don't merge tags with non-tags. Check for .bf
8082 rather than just checking whether the second character is b and
8083 the third character is f.
8084 (obj_coff_val): gcc can generate values which we don't handle
8085 correctly; discard information for now, since it only affects the
8086 debugging information.
8087 (tag_find_or_name): Don't insert tags in the symbol table.
8088 (yank_symbols): Don't merge labels.
8089 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8234 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8235 could be doing emulation.
8237 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8240 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8269 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8271 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8272 constant will not fit in an immediate field.
8273 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8275 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8308 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8310 * Support for i386-sysv.
8311 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8315 (fill_section): Don't set STYP_NOLOAD for .bss section.
8316 (fixup_segment): 386 uses strange common symbol format.

8330 fix i960+non-bfd coff bit rot.
8331 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8332 support for C source listings. (obj_coff_endef): look in the right

8335 * tc-m68k.c (get_num): make it work for all segments, not just the
8338 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8340 * configure.in: recognize i386-*-bsd emulation.

8349 * tc-z8k.c: lots of bug fixes
8351 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8353 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8354 #elif, since it is not supported by old compilers.
8355 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8356 couple of expressions in tc-m68k.c.
8358 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8360 * read.c (cons): If NO_RELOC is defined, use it.
8362 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8364 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8366 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8367 local labels to start with a .) and set REGISTER_PREFIX to %.
8368 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8370 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8372 * messages.c: Comment changes.
8374 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8377 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8379 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8381 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8384 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8386 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8387 sections starting from zero, rather than making them consecutive.
8388 This makes subsequent reloc calculations easier, esp if the object
8389 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8390 allocate lcomm in .data rather than in .bss. It seems that some
8391 tools can't cope with a non-zero sized bss before linkage.
8393 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8395 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8396 throughout. That enum no longer means what we thought it meant.
8398 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8399 "-mno-688[58]1" options.
8401 * tc-m68k.c: Added CPU32 support.
8403 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

8409 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8410 Change LIBDEPS dependence to LIBS.
8412 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8414 * Makefile.in (install): if $(tooldir) exists, install as in
8417 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8419 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8420 .word is < -32768 or > 32767. The -J flag causes the error to be
8421 ignored. This is to catch over-sized switches generated by gcc on
8422 systems which don't support the broken .word hack.
8423 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8424 write.c (fixup_segment): check for signed .word overflow if
8425 WARN_SIGNED_OVERFLOW_WORD.
8427 * write.c (fixup_segment): fixed missing parens in expression
8428 checking for byte or word overflow.
8430 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8431 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
8432 WARN_SIGNED_OVERFLOW_WORD.

8435 expression checking for byte or word overflow.
8437 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)

8912 machine is a SPARC or a 29K.
8913 * config/obj-aout.c: added s_sect pseudo op
8914 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8915 fill in the timestamp.

8937 * symbols.c (local_label_name): symbols now start with ^A.
8939 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8940 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8941 generate these sections. .align: will use NOP_OPCODE or 0
8942 for padding. This is just for being nice to the
8945 * expr.c (operand): changed to generate local label "\001L0"
8946 starting with a ^A so that it is recognized as a local label.
8948 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8950 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8951 i/o opcodes - inb, inw, outb and outw. string manipulation with
8952 att syntax - scmp, slod, smov, ssca, ssto.
8954 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8955 to just after .file .
8957 In obj_crawl_symbol_chain() where it tries to put the external
8958 symbols apart, with the condition:
8959 (!S_IS_DEFINED(symbolP) &&
8960 !S_IS_DEBUG(symbolP) &&
8961 !SF_GET_STATICS(symbolP))
8962 it was moving too many symbols out. So I switch it back to the
8964 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8966 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8967 so that we don't use the F_RELFLG which make the linker complain
8968 that somebody has stripped the relocation info.
8970 Also, the AIX ld program require that the relocation table
8971 is sorted by r_vaddr like the standard ATT assembler does.
8973 [he also changed the sizeof(struct ...)'s into the coff
8974 style FOOSZ macros. I'm not sure this is right, but I can't
8975 remember why. xoxorich.]

8979 * Makefile.in, configure.in, doc: use the doc. Build it, install
8982 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8984 * read.c: white space and comments only.
8986 * configure.in: use the new atof-ns32.c for ns32k.
8988 * write.c: comment change only.
8990 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8991 aren't yet integrated.
8993 * tc-i860.[hc]: blew off the dust. Something must still be done
8994 about conflicting relocation types.
8996 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8999 * tc-i960.c, tc-sparc.c: white space and comments only.
9001 * tc-a29k.h: delete duplicate macro definition.
9003 * new file atof-ns32k.c copied from hack's last unreleased gas.
9005 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9007 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9010 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9011 ChangeLog's prior to this are sketchy at best. I have logs.
9012 They just aren't ChangeLogs.
