520 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
522 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
523 it's better to use the one in libiberty.
525 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
527 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
528 change; it breaks the rs6000 support, and doesn't seem to be

539 rather than explicitly adding the frag address.
540 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
541 the end of the line numbers; this replaces the zero entry which
542 used to be added by coff_add_linesym, removed Oct 7.
543 (coff_adjust_section_syms): Ignore sections with no seginfo.
545 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
547 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a

565 * Makefile.in (comparison): When comparing as.new or gasp.new, try
566 running the binary through sed to avoid differences due to
567 "stage1" or "stage2" having been written into the binary.
569 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
571 ELF symbol size handling, based on code from Eric Youngdale:

604 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
606 (obj_frob_file): New macro.
608 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

634 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
636 (diststuff): New target; builds DISTSTUFF.
637 (realclean): Separate target, depend on clean and distclean, then
639 * make-gas.com: Deleted.
641 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
642 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
644 (i386_operand): Don't look up section symbol for

665 (fixup_segment): Changed local var PCREL to type int, added PLT.
666 If PC-relative fixup refers to a PLT entry for a symbol in the
667 current section, don't reduce it.

670 DEBUG5 is defined, print out each fixup before and after
672 (fixup_segment): If DEBUG5 is defined, print out each fixup before
673 and after processing.

683 * Makefile.in (all): Depend on .gdbinit.
684 (.gdbinit): Rebuild from gdbinit.in by running config.status.
686 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
688 * write.c (print_fixup): Print source location on first line.
689 Show fx_r_type and fx_addsy fields.
691 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
693 * configure.in: Set bfd_gas for all sparc targets in one place,

699 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
702 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
703 processing if add_symbol is undefined or in expr_section.
704 (resolve_symbol_value, case O_add): For symbol plus
705 constant-valued symbol, convert to O_symbol and re-reduce.

712 (print_expr_1): Fix whitespace before printing X_add_number.
714 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
715 not symbol_new, for symbols holding expression values.
716 * expr.h (make_expr_symbol): Move declaration here.
717 * write.c (fix_new_exp): Handle O_add by creating an
718 expression-valued symbol, and calling fix_new_exp recursively.
719 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
720 undefined symbol and a constant, fold the constant into the fixup,
721 and refer to the undefined symbol directly. Then process the
722 fixup again from scratch.
723 (write_object_file): Before calling adjust_reloc_syms, make a pass
724 through the symbol list trying to resolve values.
726 * write.c (print_fixup): New routine, for debugging.
727 (write_relocs): Call bfd_install_relocation. Deleted various
728 hacks for working around problems with bfd_perform_relocation.

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

745 * write.c (write_relocs): Add file name and line number to
746 as_fatal calls. Handle bfd_reloc_overflow case specifically when
747 RELOC_EXPANSION_POSSIBLE.
749 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
751 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
752 here. Use them for deciding which PRINTF*LIKE macro definitions
754 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
755 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
756 default definitions matching what we were doing before.
757 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
758 always use the varargs form if not using stdarg. It's safe to
759 always use vfprintf, because libiberty will provide it if the
760 native system doesn't. Also, always make format be const.
761 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
763 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

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

794 * config/ho-*.h: Now-unused files deleted.
796 * symbols.c (copy_symbol_attributes): New function. Copies BFD
797 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
798 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
799 zero. Don't call obj_frob_forward_symbol.
800 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

802 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
804 * config/tc-i960.c: Lots of whitespace, comment reformatting,
806 (strchr): Don't declare.

808 md_estimate_size_before_relax, md_ri_to_chars,
809 md_create_short_jump, md_create_long_jump.
810 (brtab_emit): Use data_section, not SEG_DATA.
812 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
814 * config/vms-conf.h: new file, manually derived from conf.in.
815 * config-gas.com: use it, and eliminate obsolete "host.h".
817 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
819 * config/tc-ppc.c (ppc_current_block): New static variable.
820 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

823 (ppc_bs): Set ppc_current_block.
824 (ppc_es): Clear ppc_current_block.
825 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
826 from the csect of the enclosing block.
828 * config/tc-mips.c (insns_since_cache_access): Remove.
829 (append_insn): Remove setting of insns_since_cache_access, and
830 special 4600 handling; it turns out not to be required.
832 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
834 * config/tc-mips.c (md_shortopts): Remove E.
835 (md_longopts): Add EB and EL.
836 (md_parse_option): Handle -EB and -EL as separate options, rather
837 than as a single -E option with an argument.
839 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
841 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
842 involving global symbols too.
844 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
846 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
848 * configure.in: Test for remove, not delete. Fix cross-assembler
850 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
853 * read.c (pseudo_set, case O_symbol): If
854 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.

860 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
861 many others): new macros; values obtained from "DSTRECRDS.SDL".
862 * config/obj-vms.h (various): use them.
863 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
864 representation (only enum bitfields can avoid being bitstrings).
865 (bitfield_suffix, setup_basic_type): new routines.
866 (VMS_typedef_parse): use them. Now recognize bitfields of all
867 integral types, not just type `int'. Caveat: the representation
868 used for bitfields still does not work for objects placed in
869 registers, and gcc's optimizer sometimes puts small structs there.
871 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
873 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
875 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
876 (tc_frob_label): define this to call vms_check_for_special_label,
877 and declare the latter.
878 * config/obj-vms.c (vax_g_doubles): declare this file-scope
880 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
881 (vms_check_for_special_label): new routine (tc_frob_label).
882 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
883 and `gcc2_compiled.' labels; they won't reach here any more.
884 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
885 double', use `vax_g_doubles' flag to select type of double.
886 (VMS_write_object_file) [traceback setup]: don't pass symbols
887 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
888 and TBT_Routine_End functions.
890 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
892 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
893 S_GET_VALUE() to avoid many repeated function calls.
894 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
895 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
896 gets requested. [All the HACK_DEC_C_STARTUP code appears to
897 be obsolete; gcc does it automatically for vms target. It's
898 also misnamed, because it is for the "VAX C" run-time library,
899 not the newer "DEC C" one which has much different startup code.]
900 {various}: use `S_SET_xxx(symbol,new_value)' rather than
901 `S_GET_xxx(symbol) = new_value'.
903 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
905 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
906 not &bfd_abs_section.
908 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
910 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
912 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
914 * expr.c (expr): Don't reduce the difference of two symbols in the
915 same frag if the symbols are not in normal sections.
917 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
918 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
919 (obj_attach_unwind_info): Do not define. Not needed anymore.
920 * config/tc-hppa.c: Delete whitespace at EOL.
921 (struct hppa_fix_struct): Delete fx_unwind field and all references.
922 (fix_new_hppa): Last arg is now a pointer to an int. Do not
923 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
924 fixups, store 32bits of unwind information in the fx_addnumber
926 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
927 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
928 pointer to 32 bits of unwind info.
929 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
930 pointer to the dummy symbol; set the addend field to fx_addnumber.
931 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
932 rather than &bfd_XXX_section.
934 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
936 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
937 value by one; discard adjustments previously being made. From
940 VMS- and Vax-related changes from Pat Rankin:
941 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
942 * vmsconf.sh: no longer have make-gas.com echo text about needing
943 to modify the gcc-vms driver when intending to use with gcc 1.x.
944 * as.c (parse_options): suppress 'v' from std_short_options and
945 eliminate VMS-specific conditional initialization;
946 [default case]: check for '-v' if md_parse_options doesn't recognize
948 [default case, #if VMS]: check for filename argument when '-v' seen;
950 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
951 for O_big literal operands (double floats and long long ints);
952 [VMS, md_shortopts]: add second colon after 'v';
953 (md_parse_options) [VMS, case 'v']: check for argument, so
954 caller can handle `-v' w/o arg.

958 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET

967 * flonum-konst.c: Change preprocessor tests of HO_VMS to just VMS.
968 * hex-value.c: Ditto.
969 * config/obj-vms.c: Ditto.
971 * config/tc-sparc.c (sparc_ip): Replace as_bad/exit sequence with
973 * config/tc-i860.c (i860_ip): Ditto.
974 * config/tc-hppa.c (pa_ip): Ditto.

2005 (control_regs): New pointer.
2006 (m68k_ip): Use control_regs instead of testing CPU every time.

2369 * as.c (main): If tc_init_after_args is defined, invoke it after
2370 all arguments have been processed.
2372 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2373 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2374 section instead of .text. Call create_target_segments.
2375 * read.c (demand_copy_string): No longer static.
2377 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2379 * config/tc-mips.c (append_insn): Permit branches to be switched
2380 with the preceding instruction even if .set nobopt has been seen.
2381 .set nobopt actually controls whether to bring up an instruction
2382 from the branch target, which gas does not currently support.
2384 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2386 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only
2387 when BFD_ASSEMBLER is not defined, and all conditionals relating

2391 * config/obj-coff.c: Include subsegs.h.
2392 (coff_frob_section): New function.
2393 (obj_coff_init_stab_section): New function.

2399 * config/tc-sparc.c (md_section_align): Always round up to
2400 multiple of alignment power specified in bfd target vector.
2402 * gasp.c: Include ctype.h.
2404 Mon Apr 18 21:08:01 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2413 register mask, skip empty fill frags caused by enabling listing
2416 * config/ho-sysv.h: Include string.h.
2418 * doc/internals.texi: New (well, recently added) file. Just added
2419 info on as_warn and friends.

2423 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2424 defaults for defined, private, and spnum fields for the
2425 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
2426 not reset the segment if just updating a space.
2427 (pa_spaces_begin): Set BFD section flags for all built-in
2430 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2433 (add_procedure): Set first_proc_ptr if it hasn't been set.
2434 (ecoff_build_lineno): If the first procedure does not start at
2435 address zero, insert a dummy line to compensate.
2437 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2440 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2442 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2443 floating point and binary numbers respectively; if it doesn't
2444 work, treat them as local labels.
2446 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2447 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2449 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2451 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2452 source files from other directories into objects in the current
2453 directory, and specify PSECT attributes explicitly to linker.
2454 Also added missing label.
2455 * Makefile.in (stamp-mk.com): Reference new variable
2456 VMS_OTHER_OBJS for list of non-local object files, instead of
2458 (VMS_OTHER_OBJS): New variable, added more libiberty files.

2461 * config/ho-vms.h (unlink): Define as delete.
2463 * config-gas.com: Fix quoting on TARGET_CANONICAL definition.

2468 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
2470 * config/tc-mips.h (DIFF_EXPR_OK): Define.
2471 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2472 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2473 argument, the reloc type.
2474 (load_register): Pass reloc type to macro_build for 'u'.
2475 (macro): Likewise. For M_LA_AB permit a difference expression
2476 when generating embedded PIC code between an arbitrary symbol and
2477 a symbol in the .text section.
2478 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2479 BFD_RELOC_PCREL_LO16 to be emitted.
2480 (md_apply_fix): Check that most relocs are not PC relative.
2481 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.

2483 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
2485 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
2487 * subsegs.c (subsegs_begin): Call memset with args in the correct
2489 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2490 to NULL instead of 0.
2492 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2494 * config/tc-hppa.c (pa_procend): Handle case where label was
2495 defined after the .proc directive.
2497 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2498 procend for a procedure without a name.
2500 Thu Apr 7 14:28:30 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2502 * config/tc-mips.c (macro): Pass NULL for expression argument to
2503 macro_build for nori case.

2512 Thu Apr 7 10:38:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2514 * config/tc-hppa.h (elf_tc_symbol): Delete. No longer used.

2519 (hppa_tc_symbol): Likewise.
2521 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2522 elf_tc_make_sections stuff. It was there to support PA braindamage
2523 which has been fixed, and in the case of elf_tc_make_sections is
2524 redundant with elf_tc_final_processing.
2526 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2528 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
2531 Tue Apr 5 15:48:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2533 * config/tc-mips.c (mips_ip): For case 'o', when generating
2534 embedded PIC code, accept the difference between two local symbols
2536 (mips_force_relocation): Only force a reloc to be generated for a
2538 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
2539 value into the file if the fixup will not generate a reloc.
2541 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
2543 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2544 don't spew remainder of input file in error message.
2545 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2546 message with reloc type and try to process remainder of file.
2548 * doc/Makefile.in (install-info-as, install-info-gasp): New
2549 targets, now explicitly checking $(srcdir) for info files.
2550 (install-info): Depend on both of them; do nothing more.
2552 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
2554 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2556 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2558 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2559 flag rather than signedp field. Only permit extended range if
2560 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2561 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2563 * config/tc-ppc.c (ppc_size): New static variable.
2564 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2565 (md_begin): If an instruction has a size specific flag set, only
2566 add it if we are assembling that size.
2568 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2570 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2571 cross section PC relative relocs right for COFF and ELF.
2573 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2575 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2576 (OBJ_PROCESS_STAB): Don't define.
2578 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2580 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2581 the type of symbol set symbols which happen to be in the absolute
2582 or undefined section.
2584 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2586 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2587 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2588 and -many (all architectures).
2590 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2592 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2593 involving a function symbol which is not a plabel to zero.
2594 (md_apply_fix): Never pass a function symbol to field_adjust.
2596 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2598 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2599 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2601 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2602 branch with an instruction that uses $at, in case the branch is
2604 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2605 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2606 to make it pcrel_offset.
2607 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2608 reloc->address; another gruesome hack to get gas reloc handling to
2611 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2613 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2616 (emit_insn): New function.
2617 (md_assemble): Call it.
2618 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2620 (lituse_pending): New variable. Set by anything that generates a
2621 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2622 tested by code that might want to emit a LITUSE reloc.
2623 (emit_unaligned_io): New function. Currently calls md_assemble,
2624 but it should eventually be converted to generate the insn itself
2625 and call emit_insn directly.
2626 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2627 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2628 emit_bis_r): Likewise.
2629 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2630 (alpha_ip, label get_macro): Don't emit the final instruction if
2632 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2633 unaligned memory access macros.
2634 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2635 the value can't be resolved.
2637 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2639 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2640 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2641 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2643 (mips_force_relocation): New function.
2644 (md_apply_fix): Set fixP->fx_done appropriately.
2645 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2653 * config/tc-mips.c (enum mips_pic_level): New enum.
2654 (mips_pic): Change from int to enum mips_pic_level. Change all
2655 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2656 (load_address): Handle EMBEDDED_PIC.
2657 (macro): Handle EMBEDDED_PIC in all PIC cases.
2658 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2659 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2660 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2661 works). Do not permit -G with SVR4_PIC.
2662 (s_abicalls): Warn if -G was used, and force -G 0.
2663 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2664 anything but a.out, not just for ELF. For ECOFF, don't generate a
2665 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2667 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2669 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2671 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2672 parameters to avoid losing when compiling with HP CC.
2673 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2675 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2677 * Makefile.in (config-stamp): If `defs' is defined, emit a
2678 preprocessor directive to create a macro named by this value into
2679 config.new; don't explicitly go for BFD_ASSEMBLER.
2680 * configure.in: Define `defs', not `BFDDEF'. Set it to
2681 MANY_SEGMENTS for any obj-coffbfd target.
2682 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2683 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2685 (LOCAL_LOADLIBES): Deleted.
2686 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2687 * config/m88kcoff.mt (TDEFINES): Ditto.
2688 * config/ebmon29k.mt: Deleted.
2689 * config/h8300hds.mt: Deleted.
2690 * config/ic960coff.mt: Deleted.
2691 * config/sparc.mt: Deleted.
2692 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2693 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2694 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2695 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
2696 (TDEFINES): Don't define the coffbfd macros.

2713 bfd_set_symtab is called.
2714 (dump_section_relocs): Note whether a symbol is a section symbol
2716 (adjust_reloc_syms): For now, always supply an absolute symbol for
2717 fixups without symbols but not yet `done'. Use section_symbol to
2718 get the symbol, instead of going directly for abs_symbol.
2719 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2720 reloc is not a section symbol and is not in the symbol table.
2721 (set_symtab): New function, broken out from write_object_file.
2722 Counts symbol table instead of relying on an earlier count.
2723 (write_object_file): Call set_symtab, but do it after potentially
2724 invoking the *_frob_file macros. Don't bother counting symbols.
2725 Call symbol_remove, instead of expanding it in place. Moved the
2726 conditionalized `object_file_size' declaration down to
2727 conditionalized block where it's used. When using the absolute
2728 symbol for a fixup without a symbol, set sy_used_in_reloc.
2729 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2730 the correct symbol for the absolute section.
2732 * subsegs.c (section_symbol): Use symbol_new instead of
2733 symbol_make, since we may want it to go into the symbol table.
2734 Make the new symbol have internal linkage. If
2735 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2736 symbol with the newly created GAS symbol.
2737 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2738 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2740 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
2742 * config/tc-sparc.c: Include subsegs.h.
2743 (in_signed_range): New function.
2745 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2746 (sparc_ip, label "immediate"): Reject constants for pcrel
2747 instructions only if the relocation type indicates a "call"
2748 instruction and the offset is within range of a "jmpl %g0". If
2749 it's not in range, use the absolute section symbol plus an offset.
2750 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2752 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2754 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2757 * configure.in: Eliminated all targets using obj-coff but not
2758 defining BFD_ASSEMBLER; I think all such targets that are
2759 supported will be matched by real CPU-OS combinations earlier in
2761 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2762 some comments about the dpx2 configuration, but left it disabled,
2763 since it couldn't be reached before.
2764 (target a29k-amd-ebmonold): Deleted.
2766 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2768 * config/tc-hppa.c (pa_import): Correctly handle importing of an
2769 already defined symbol.
2771 Wed Mar 16 17:11:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2773 * config/tc-mips.c (mips_ip): Only accept overly large values for
2774 the 'j' operand if there are no further alternatives for this
2777 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2778 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2779 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2781 * config/tc-mips.c (mips_align): Take new argument, label, and use
2782 it instead of global insn_label.
2783 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2784 call to mips_emit_delay and pass it to mips_align.
2786 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2788 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2790 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2791 argument to a .callinfo directive. Don't loop forever on errors.
2793 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2794 use pre-defined registers as arguments.
2796 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2798 * write.c (write_object_file): Check both S_IS_LOCAL and
2799 S_IS_EXTERNAL when deciding whether to discard a symbol.
2801 * config-gas.com: Scan Makefile.in, not version.c, for current
2802 version number. Delete all versions of temp files when finished
2803 with them. Create config.h.
2805 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2806 values to reduce number of lookups with S_GET_VALUE. Skip debug
2807 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2808 holger@botbso.rhein-main.de.)
2809 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2810 field. (Also from Holger Teutsch.) Watch for a would-be register
2811 mask that spans frags.
2813 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2814 this_base, not line_base. (Patch from Andreas Arens,
2815 ari@obelix.av.rwth-aachen.de.)
2817 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that

4612 pass new argument for i, j and o cases.
4613 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4951 for keeping or rejecting configurations still under development;
4952 default is to assume production environment, and reject configs
4953 still being worked on. Mark Elf configurations (except sparc and
4954 i386) as developmental. Deleted cases matching some generic names
4955 in favor of more specific names. (E.g., when we get Alpha

4972 through inclusion of tc-hppa.h. Delete all forward declarations
4973 for functions only used within tc-hppa.c, likewise for structures,
4974 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4975 conditional code in a few small places.
4977 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4978 structures, global variables, forward declarations together.

4980 conditional code -- try to group conditional code together
4981 into a few places. Make all functions and variables which
4982 are only used within tc-hppa.c static. PARAMize all functions.
4983 Add comments to functions. Delete unused functions, variables,
4984 #defines, etc. Delete unused members within structures. Delete
4985 ldil;ble hacks -- it is believed they were installed to work
4986 around old gas bugs. Avoid using mixed case for local
4987 functions, variables, and structures. Fix formatting problems
4988 not found by GNU-indent. Add FIXME notices for things which
4989 should be worked on the near future. Delete lots of old
4990 useless (1.36 PA-SOM) code.

5069 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5071 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5072 ELF, since the ELF object format does not have these type of
5073 relocations. Change the abort into as as_bad and return
5074 BFD_RELOC_NONE to silence compiler warnings.
5075 (md_assemble): Keep track of the instruction size. Allow white
5076 space between the $ and the constant for compatibility with older
5077 gases and other assemblers.

6087 are also magic, and have special default flag settings.
6088 (obj_elf_frob_symbol): Since the return value from this function
6089 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6090 doesn't accomplish anything else.

6102 undefined_section for the return value.
6104 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6105 pseudo-op with a poc_handler field of NULL, ignore it and treat it
6106 as an instruction instead.

6152 * Extensive changes to permit symbols to contain any expression
6153 type and to delay the computation of the expression until the
6154 value is actually needed. This permits setting symbols to values
6155 calculated based on object code size. Expressions were changed to
6156 no longer be in a section, to stop the overloading of segment and
6157 expression type that previously occurred.
6159 * as.c (big_section, pass1_section, diff_section, absent_section):
6161 (expr_section): Added (used for dummy symbols which hold

6245 (previous_section, previous_subsection): New vars.
6246 (obj_elf_section): Save current place in case DWARF code wants us
6247 to pop back to it. Handle unquoted section name as well as quoted
6248 section name. Don't crash on invalid strings.
6249 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6252 * config/obj-elf.h: Don't include struc-symbol.h.

6361 sy_resolved and sy_resolving single bit fields.
6362 * symbols.c (symbol_new): Don't initialize sy_forward field.

7510 avoid some redefinition complaints on some systems.
7511 (const, volatile): Don't need these conditionally defined if we
7512 use CONST and VOLATILE from ansidecl.h.

7561 dropping a space immediately following an identifier.
7562 * expr.c, write.c: Rewrote assert expressions to not use multiple
7563 lines; I don't think that can be done portably.
7564 * config/tc-mips.c (macro): Use $AT if target register is zero in
7565 load instruction, which it can be for a floating point load.

7639 prototypes for all static functions. Moved existing minimal
7640 debugging format support info #ifndef OBJ_ECOFF blocks.

7689 * make-gas.com: Find obstack.obj if it's not in the current
7691 * read.c (s_ignore): Don't declare is_end_of_line. It's
7692 redundant, and triggers a VMS gcc compiler bug.
7694 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7695 current segment as an argument. (Ignored in all cases but VMS.)
7696 All callers and definitions changed.

7720 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7723 * configure.in: mips-bsd configuration was missing format spec.
7726 * Makefile.in (Makefile): Depends on configure.in.
7728 * config/tc-mips.c (append_insn): Don't check for alignment of
7729 frag in memory; alignment of instructions in section is a separate

7750 constants are accepted, but symbolic values are not. GCC will not
7751 generate the latter currently.
7753 * frags.c (frag_init): New function.
7754 (zero_address_frag, bss_address_frag): Now initialized at run
7756 * as.c (main): Call frag_init.

8006 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8007 md_relax_table): Use default zero initialization.
8008 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8009 latter, instead of selecting with preprocessor conditionals.
8011 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8013 * configure.in: recognise all sparclite variants
8015 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8021 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8023 * expr.c (operand): If character other than comma or newline is a
8024 logical end-of-line character, use the newline case.
8025 From Eric Youngdale:
8026 (operand): Set X_add_number field for floating-point numbers.
8027 (operand): Treat zero byte as end-of-operand.
8029 * configure.in (per-target): Look for with_bfd_assembler option.
8030 For now, only accept "no", until the merge is done.
8032 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8033 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8034 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8035 * read.c: Finish conversion to S_* macros in the VMS only
8036 parts of the program. Add "const" modifier to hex_value.
8037 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8039 * expr.c: Add "const" modifier to hex_value.
8040 * symbols.c: Finish conversion to S_* macros in the VMS only
8041 parts of the program. Add "const" modifier to
8042 md_[long,short]_jump_size. Remove declaration of const_flag
8043 (which will be declared in obj-vms.h).
8044 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8045 Fix arguments to VMS_write_object_file.
8046 * config-gas.com: New file. Script for VMS systems to set up the
8047 configuration to build gas for VMS, and create config.status.
8048 * make-gas.com: Redone to work with new scheme.
8049 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8051 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8052 will swap bytes if needed on a big endian system. Use throughout
8054 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8055 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8056 types of malformed stabs. Change parsing algorithm so that we are
8057 more certain of having all of the information that we need on hand.
8058 * obj-vms.c (final_forward_reference): New function, used to help
8059 resolve the data types of as many struct elements as possible
8060 when some part of the struct is not fully defined by the compiler.

8063 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8064 as symbols as well in the object file. Look for external functions
8065 that start with "__vt.", and turn them into variables, since the
8066 g++ compiler is incapable of doing this.
8067 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8069 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8070 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8071 have the name of the source file yet.
8072 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8074 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8076 * read.c (s_data): Always use "data_section", since it'll map to
8077 SEG_DATA or SEG_E1 if needed.
8078 (s_lcomm): Likewise with bss_section.
8079 (s_fill): Use memset, not bzero.
8081 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8102 (section_alignment): Declare only if not BFD_ASSEMBLER.
8103 (big_section, reg_section, pass1_section, diff_section,
8104 absent_section, text_section, data_section, bss_section): If
8105 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8106 mapping to segT enum values.
8107 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8108 if these are used or defined, if BFD_ASSEMBLER.
8109 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8110 subseg_new split into two functions.
8111 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8113 * as.h (volatile): Don't define if already defined.
8114 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8116 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8117 declare with format attribute for -Wformat checking.
8119 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8121 * app.c, config/tc-*.c: Don't include read.h, since it is already
8124 * These are based on patches from Minh Tran-le
8125 <mtranle@paris.intellicorp.com>.
8126 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8127 obj_format coffbfd and gas_target i386coff for target.
8128 (i[34]86-*-isc*): New host (uses sysv).
8129 * config/i386aix.mt: Removed (no longer used).
8130 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8132 (LDFLAGS): Added, defined as -shlib.
8133 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8134 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8135 (DOT_LABEL_PREFIX): Define.
8136 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8137 name rather than L0\001.
8138 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8140 * symbols.c, symbols.h (local_bss_counter): Removed.
8141 * write.c (write_object_file): bss no longer uses

8149 (size_section): Restored sanity check.
8150 (do_relocs_for): Base section address on s_paddr rather than
8151 computing it. Adjust a29k R_IHIHALF special case to account for
8152 section paddr (used to require paddr to be zero). If there are no
8153 reclos, set s_relptr to 0. Set relocation size in object_headers.
8154 (fill_section): Always set s_vaddr here, removing
8155 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8156 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8157 Set STYP_INFO for .comment.

8161 H_{SET,GET}_* macros.
8162 (do_linenos_for): Set lineno size in object_headers.
8163 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8164 set s_vaddr here. If string_byte_count remains 4, set it back to
8165 0, and only write strings out if there are some. Call
8166 fill_section before do_relocs_for and do_linenos_for.
8167 (obj_coff_section): Handle optional quoted second argument giving
8168 section characteristics.
8169 (obj_coff_bss): Added to handle .bss.
8170 (obj_coff_ident): Added to handle .ident (puts string in .comment

8190 (do_scrub_next_char): For \", return " not '.
8191 (symbol_chars): Now const.
8193 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8194 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8196 * config/obj-coff.h: Don't use #elif.
8198 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8199 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8226 using ZERO_BASED_SEGMENTS.
8227 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8228 never set segment address for SEG_E2 (.bss) and don't write out
8229 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8230 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8231 definitions, and don't merge tags with non-tags. Check for .bf
8232 rather than just checking whether the second character is b and
8233 the third character is f.
8234 (obj_coff_val): gcc can generate values which we don't handle
8235 correctly; discard information for now, since it only affects the
8236 debugging information.
8237 (tag_find_or_name): Don't insert tags in the symbol table.
8238 (yank_symbols): Don't merge labels.
8239 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8442 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8443 so widening works consistently.
8445 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8447 * version.c: Put conditional "const" before version_string, not
8448 before dummy function for VMS. Now version 1.91.03.
8450 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8451 printed rep of null character.
8453 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
8455 * obj-coffbfd.c (write_object_file): check return value of
8458 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8460 * Support for i386-sysv.
8461 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8462 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8463 be used to set them all to zero as was done before.
8464 (fill_section): segment addresses now set in write_object_file.
8465 (fill_section): Don't set STYP_NOLOAD for .bss section.
8466 (fixup_segment): 386 uses strange common symbol format.
8467 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8468 compatibility with SVR3.2 linker.
8469 * configure.in: i386-sysv and i386-sco use coffbfd.

8480 fix i960+non-bfd coff bit rot.
8481 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8482 support for C source listings. (obj_coff_endef): look in the right
8483 part of the symbol for the symbol name
8485 * tc-m68k.c (get_num): make it work for all segments, not just the
8488 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

8499 * tc-z8k.c: lots of bug fixes
8501 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8503 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8504 #elif, since it is not supported by old compilers.
8505 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8506 couple of expressions in tc-m68k.c.
8508 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8510 * read.c (cons): If NO_RELOC is defined, use it.
8512 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8514 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8516 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8517 local labels to start with a .) and set REGISTER_PREFIX to %.
8518 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8534 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8536 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8537 sections starting from zero, rather than making them consecutive.
8538 This makes subsequent reloc calculations easier, esp if the object
8539 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8540 allocate lcomm in .data rather than in .bss. It seems that some
8541 tools can't cope with a non-zero sized bss before linkage.
8543 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8545 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8564 * Makefile.in (install): if $(tooldir) exists, install as in
8567 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8569 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8570 .word is < -32768 or > 32767. The -J flag causes the error to be
8571 ignored. This is to catch over-sized switches generated by gcc on
8572 systems which don't support the broken .word hack.
8573 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8574 write.c (fixup_segment): check for signed .word overflow if
8575 WARN_SIGNED_OVERFLOW_WORD.
8577 * write.c (fixup_segment): fixed missing parens in expression
8578 checking for byte or word overflow.

8594 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8596 * input-scrub.c (input_scrub_push): call input_file_begin, not
8598 messages.c (as_perror): print ": " between the passed in error and
8599 the strerror, like perror does.
8601 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8604 From Steve Chamberlain:
8605 Makefile.in: Handle m68*-*-coff*.
8606 read.c, read.h: add mult argument to s_space
8608 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8609 Motorola and MIT syntax; gas can now assemble either type of
8611 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8619 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8621 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8624 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8626 * Makefile.in (LIBS): Include opcode library.

8651 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8653 * config/tc-m68k.c (init_table): Now const. Always include 68851
8654 data, so that "bc" is available to 68040 cache instructions.
8655 Added "tt0", "tt1", and 68ec030 variants.
8656 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8657 (enum _register): Added TT0, TT1.
8658 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8659 line number correctly in "internal error" messages. Don't print
8660 architecture-mismatch message for operand errors.
8662 From Colin Smith (colin@wrs.com):
8663 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8664 than install_operand.

8685 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8686 has already been formatted (but may still contain %-characters).
8689 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8691 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8692 written with indirection on the last two operands, which can be
8693 either data or address registers. Added a new operand type 'r'
8694 which accepts either register type. Added '(' to notend stuff in
8695 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8714 their not having symbols associated.
8716 * tc-i960.c (norelax, instrument_branches): Default initializer is

8802 ancient or broken compilers.
8804 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
8805 processor/opcode mismatch, so reword the error message.

8920 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8922 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
8923 calc the base of relocs correctly.
8924 * tc-a29k.c (parse_operand): allow expressions to be in any section.
8926 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
8928 * as.c, write.c: use -K rather than -k for the broken word warning
8931 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
8933 * Makefile.in: do not print recursion lines.
8935 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8937 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
8939 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8941 * write.c (write_object_file): For b.out format, round up section
8942 start addresses to match required alignment.
8944 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8946 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8947 where gcc looks for it.
8949 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8951 * Makefile.in: Changed some lines to be less confusing for some
8954 * input-file.c: Conditionalize on _IOFBF, not VMS.
8956 * read.c, write.c: Change a series of ifdef/elif to
8957 ifdef/else/ifdef etc.
8959 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
8961 * symbols.c (fb_label_init): fix sizeof to memset.
8963 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
8965 * Makefile.in: install the man page.
8967 * Makefile.in: pass down MAKEINFO explicitly on info.
8969 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
8971 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8973 * flonum-const.c: renamed flonum-konst.c to stop dos name
8976 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8978 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8979 tc-m68k.h to te-sun3.h.
8981 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8983 * configure.in: vxworks68 gets te-sun3.h.
8985 * expr.c: remove limitation that local_labels_dollar or
8986 local_labels_fb must be < 10.
8988 * symbols.c: remove local_labels_dollar, replace with a function
8989 interface for a sparse array. All users adjusted.
8991 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
8993 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8995 * doc/Makefile.in: commented out line for building as-all.texinfo.
8998 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9000 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9002 * Makefile.in: added check target.
9004 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9006 * Makefile.in: added tooldir and program_prefix.
9008 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9010 * write.{c,h} (fix_new): Make these declarations consistent.
9012 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9014 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9017 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9019 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9021 * expr.c (operand): if can't work out what sort of operand it is,
9022 then look through FLT_CHARS for a hint.
9024 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9026 * Makefile.in, configure.in: removed traces of namesubdir,
9027 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9028 copyrights to '92, changed some from Cygnus to FSF.
9030 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9031 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9032 copyrights to '92, changed some from Cygnus to FSF.
9034 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9036 * expr.c: If an expression is single comma, then return with
9037 SEG_ABSENT rather than an error - since the sparc front end does
9038 really strange things with things like fbge,a
9040 * as.h: include bfd.h if using many sections
9041 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9042 local labels didn't work.
9043 * listing.c (list_symbol_table): don't core dump when there's no
9045 * write.c, write.h: call fix_new with the right number of args on
9047 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9050 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9052 * app.c: MRI compatibility - allow single quote to start a string.
9053 * as.c: fix typo recently introduced.
9054 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9055 * expr.c: Much rewriting, to accomodate MRI syntax for
9056 expressions. Also easier to read now.
9057 * listing.c: Put back defuns
9058 * read.c: modified to accept MRI syntax, put back listing pseudo
9059 ops so that an assembler built with NO_LISTING ignores list ops
9061 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9062 machine is a SPARC or a 29K.
9063 * config/obj-aout.c: added s_sect pseudo op
9064 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9065 fill in the timestamp.
9066 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9067 anymore, define all the relocs which the tc-<x> bit will use so we
9068 can translate from them to the coff types.
9069 * config/tc-a29k.c: reloc_type isn't ane enum any more
9070 * config/tc-m68k.c: Added NO_RELOC definition.
9072 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9074 * Makefile.in: put header files before C source for TAGS; remove
9075 references to non-existent syscalls.h.
9077 * read.c, write.c subsegs.c: back out the .bss changes.
9079 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9081 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9085 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9087 * symbols.c (local_label_name): symbols now start with ^A.
9089 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9090 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9091 generate these sections. .align: will use NOP_OPCODE or 0
9092 for padding. This is just for being nice to the
9095 * expr.c (operand): changed to generate local label "\001L0"
9096 starting with a ^A so that it is recognized as a local label.
9098 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9100 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9101 i/o opcodes - inb, inw, outb and outw. string manipulation with
9102 att syntax - scmp, slod, smov, ssca, ssto.
9104 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9105 to just after .file .
9107 In obj_crawl_symbol_chain() where it tries to put the external
9108 symbols apart, with the condition:
9109 (!S_IS_DEFINED(symbolP) &&
9110 !S_IS_DEBUG(symbolP) &&
9111 !SF_GET_STATICS(symbolP))
9112 it was moving too many symbols out. So I switch it back to the
9114 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9116 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9117 so that we don't use the F_RELFLG which make the linker complain
9118 that somebody has stripped the relocation info.
9120 Also, the AIX ld program require that the relocation table
9121 is sorted by r_vaddr like the standard ATT assembler does.
9123 [he also changed the sizeof(struct ...)'s into the coff
9124 style FOOSZ macros. I'm not sure this is right, but I can't
9125 remember why. xoxorich.]
9127 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9129 * Makefile.in, configure.in, doc: use the doc. Build it, install
9132 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9134 * read.c: white space and comments only.
9136 * configure.in: use the new atof-ns32.c for ns32k.
9138 * write.c: comment change only.
9140 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9141 aren't yet integrated.
9143 * tc-i860.[hc]: blew off the dust. Something must still be done
9144 about conflicting relocation types.
9146 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9149 * tc-i960.c, tc-sparc.c: white space and comments only.
9151 * tc-a29k.h: delete duplicate macro definition.
9153 * new file atof-ns32k.c copied from hack's last unreleased gas.
9155 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9157 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9160 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9161 ChangeLog's prior to this are sketchy at best. I have logs.
9162 They just aren't ChangeLogs.
9169 version-control: never
