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

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

572 * Makefile.in (comparison): When comparing as.new or gasp.new, try
573 running the binary through sed to avoid differences due to
574 "stage1" or "stage2" having been written into the binary.
576 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
578 ELF symbol size handling, based on code from Eric Youngdale:
579 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
580 expression pointer to the symbol structure, used for `size'
581 expressions that couldn't be reduced to constants when initially
583 (elf_frob_symbol): Declare.
584 (obj_frob_symbol): Call elf_frob_symbol always, rather than
585 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.
586 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
588 (obj_elf_size): Deleted unused code. If size is non-reducible

611 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
613 (obj_frob_file): New macro.
615 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

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

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

677 DEBUG5 is defined, print out each fixup before and after
679 (fixup_segment): If DEBUG5 is defined, print out each fixup before
680 and after processing.

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

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

715 (print_symbol_value_1): Don't print frag address if it matches
716 zero_address_frag. Don't print "resolving" if already resolved.
717 Print segment name. Don't call print_expr_1 on an undefined
719 (print_expr_1): Fix whitespace before printing X_add_number.
721 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
722 not symbol_new, for symbols holding expression values.
723 * expr.h (make_expr_symbol): Move declaration here.
724 * write.c (fix_new_exp): Handle O_add by creating an
725 expression-valued symbol, and calling fix_new_exp recursively.
726 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
727 undefined symbol and a constant, fold the constant into the fixup,
728 and refer to the undefined symbol directly. Then process the
729 fixup again from scratch.
730 (write_object_file): Before calling adjust_reloc_syms, make a pass
731 through the symbol list trying to resolve values.
733 * write.c (print_fixup): New routine, for debugging.
734 (write_relocs): Call bfd_install_relocation. Deleted various
735 hacks for working around problems with bfd_perform_relocation.

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

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

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

801 * config/ho-*.h: Now-unused files deleted.
803 * symbols.c (copy_symbol_attributes): New function. Copies BFD
804 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
805 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
806 zero. Don't call obj_frob_forward_symbol.
807 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

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

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

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

867 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
868 many others): new macros; values obtained from "DSTRECRDS.SDL".
869 * config/obj-vms.h (various): use them.
870 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
871 representation (only enum bitfields can avoid being bitstrings).
872 (bitfield_suffix, setup_basic_type): new routines.
873 (VMS_typedef_parse): use them. Now recognize bitfields of all
874 integral types, not just type `int'. Caveat: the representation
875 used for bitfields still does not work for objects placed in
876 registers, and gcc's optimizer sometimes puts small structs there.
878 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
880 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
882 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
883 (tc_frob_label): define this to call vms_check_for_special_label,
884 and declare the latter.
885 * config/obj-vms.c (vax_g_doubles): declare this file-scope
887 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
888 (vms_check_for_special_label): new routine (tc_frob_label).
889 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
890 and `gcc2_compiled.' labels; they won't reach here any more.
891 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
892 double', use `vax_g_doubles' flag to select type of double.
893 (VMS_write_object_file) [traceback setup]: don't pass symbols
894 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
895 and TBT_Routine_End functions.
897 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
899 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
900 S_GET_VALUE() to avoid many repeated function calls.
901 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
902 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
903 gets requested. [All the HACK_DEC_C_STARTUP code appears to
904 be obsolete; gcc does it automatically for vms target. It's
905 also misnamed, because it is for the "VAX C" run-time library,
906 not the newer "DEC C" one which has much different startup code.]
907 {various}: use `S_SET_xxx(symbol,new_value)' rather than
908 `S_GET_xxx(symbol) = new_value'.
910 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
912 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
913 not &bfd_abs_section.
915 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
917 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
919 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
921 * expr.c (expr): Don't reduce the difference of two symbols in the
922 same frag if the symbols are not in normal sections.
924 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
925 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
926 (obj_attach_unwind_info): Do not define. Not needed anymore.
927 * config/tc-hppa.c: Delete whitespace at EOL.
928 (struct hppa_fix_struct): Delete fx_unwind field and all references.
929 (fix_new_hppa): Last arg is now a pointer to an int. Do not
930 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
931 fixups, store 32bits of unwind information in the fx_addnumber
933 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
934 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
935 pointer to 32 bits of unwind info.
936 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
937 pointer to the dummy symbol; set the addend field to fx_addnumber.
938 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
939 rather than &bfd_XXX_section.
941 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
943 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
944 value by one; discard adjustments previously being made. From
947 VMS- and Vax-related changes from Pat Rankin:
948 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
949 * vmsconf.sh: no longer have make-gas.com echo text about needing
950 to modify the gcc-vms driver when intending to use with gcc 1.x.
951 * as.c (parse_options): suppress 'v' from std_short_options and
952 eliminate VMS-specific conditional initialization;
953 [default case]: check for '-v' if md_parse_options doesn't recognize
955 [default case, #if VMS]: check for filename argument when '-v' seen;
957 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
958 for O_big literal operands (double floats and long long ints);
959 [VMS, md_shortopts]: add second colon after 'v';
960 (md_parse_options) [VMS, case 'v']: check for argument, so
961 caller can handle `-v' w/o arg.
963 Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)
965 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET

968 (tc_reloc_mangle): Deleted.
969 * config/tc-sh.h (TC_KEEP_FX_OFFSET): Define.
970 (TC_RELOC_MANGLE): Delete.
972 Tue Sep 13 16:20:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2367 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2369 * listing.c (list_symbol_table): Don't print register symbols as
2372 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2373 underscores, since symbol_new will already have done it.
2374 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2376 * as.c (main): If tc_init_after_args is defined, invoke it after
2377 all arguments have been processed.
2379 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2380 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2381 section instead of .text. Call create_target_segments.
2382 * read.c (demand_copy_string): No longer static.
2384 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2386 * config/tc-mips.c (append_insn): Permit branches to be switched
2387 with the preceding instruction even if .set nobopt has been seen.
2388 .set nobopt actually controls whether to bring up an instruction
2389 from the branch target, which gas does not currently support.
2391 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2393 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only
2394 when BFD_ASSEMBLER is not defined, and all conditionals relating
2395 to such code. No such targets remain.

2398 * config/obj-coff.c: Include subsegs.h.
2399 (coff_frob_section): New function.
2400 (obj_coff_init_stab_section): New function.

2406 * config/tc-sparc.c (md_section_align): Always round up to
2407 multiple of alignment power specified in bfd target vector.
2409 * gasp.c: Include ctype.h.
2411 Mon Apr 18 21:08:01 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2420 register mask, skip empty fill frags caused by enabling listing
2423 * config/ho-sysv.h: Include string.h.
2425 * doc/internals.texi: New (well, recently added) file. Just added
2426 info on as_warn and friends.

2430 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2431 defaults for defined, private, and spnum fields for the
2432 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
2433 not reset the segment if just updating a space.
2434 (pa_spaces_begin): Set BFD section flags for all built-in
2437 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2439 * ecoff.c (first_proc_ptr): New static variable.
2440 (add_procedure): Set first_proc_ptr if it hasn't been set.
2441 (ecoff_build_lineno): If the first procedure does not start at
2442 address zero, insert a dummy line to compensate.
2444 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2447 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2449 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2450 floating point and binary numbers respectively; if it doesn't
2451 work, treat them as local labels.
2453 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2454 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2456 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2458 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2459 source files from other directories into objects in the current
2460 directory, and specify PSECT attributes explicitly to linker.
2461 Also added missing label.
2462 * Makefile.in (stamp-mk.com): Reference new variable
2463 VMS_OTHER_OBJS for list of non-local object files, instead of
2465 (VMS_OTHER_OBJS): New variable, added more libiberty files.
2466 * make-gas.com: Regenerated.
2468 * config/ho-vms.h (unlink): Define as delete.
2470 * config-gas.com: Fix quoting on TARGET_CANONICAL definition.

2475 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
2477 * config/tc-mips.h (DIFF_EXPR_OK): Define.
2478 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2479 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2480 argument, the reloc type.
2481 (load_register): Pass reloc type to macro_build for 'u'.
2482 (macro): Likewise. For M_LA_AB permit a difference expression
2483 when generating embedded PIC code between an arbitrary symbol and
2484 a symbol in the .text section.
2485 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2486 BFD_RELOC_PCREL_LO16 to be emitted.
2487 (md_apply_fix): Check that most relocs are not PC relative.
2488 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
2489 (tc_gen_reloc): Change #error to as_fatal. Handle
2490 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
2492 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
2494 * subsegs.c (subsegs_begin): Call memset with args in the correct
2496 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2497 to NULL instead of 0.
2499 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2501 * config/tc-hppa.c (pa_procend): Handle case where label was
2502 defined after the .proc directive.
2504 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2505 procend for a procedure without a name.
2507 Thu Apr 7 14:28:30 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2509 * config/tc-mips.c (macro): Pass NULL for expression argument to
2510 macro_build for nori case.

2519 Thu Apr 7 10:38:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2521 * config/tc-hppa.h (elf_tc_symbol): Delete. No longer used.

2526 (hppa_tc_symbol): Likewise.
2528 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2529 elf_tc_make_sections stuff. It was there to support PA braindamage
2530 which has been fixed, and in the case of elf_tc_make_sections is
2531 redundant with elf_tc_final_processing.
2533 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2535 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
2538 Tue Apr 5 15:48:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2540 * config/tc-mips.c (mips_ip): For case 'o', when generating
2541 embedded PIC code, accept the difference between two local symbols
2543 (mips_force_relocation): Only force a reloc to be generated for a
2545 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
2546 value into the file if the fixup will not generate a reloc.
2548 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
2550 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2551 don't spew remainder of input file in error message.
2552 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2553 message with reloc type and try to process remainder of file.
2555 * doc/Makefile.in (install-info-as, install-info-gasp): New
2556 targets, now explicitly checking $(srcdir) for info files.
2557 (install-info): Depend on both of them; do nothing more.
2559 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
2561 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2563 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2565 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2566 flag rather than signedp field. Only permit extended range if
2567 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2568 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2570 * config/tc-ppc.c (ppc_size): New static variable.
2571 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2572 (md_begin): If an instruction has a size specific flag set, only
2573 add it if we are assembling that size.
2575 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2577 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2578 cross section PC relative relocs right for COFF and ELF.
2580 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2582 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2583 (OBJ_PROCESS_STAB): Don't define.
2585 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2587 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2588 the type of symbol set symbols which happen to be in the absolute
2589 or undefined section.
2591 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2593 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2594 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2595 and -many (all architectures).
2597 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2599 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2600 involving a function symbol which is not a plabel to zero.
2601 (md_apply_fix): Never pass a function symbol to field_adjust.
2603 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2605 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2606 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2608 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2609 branch with an instruction that uses $at, in case the branch is
2611 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2612 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2613 to make it pcrel_offset.
2614 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2615 reloc->address; another gruesome hack to get gas reloc handling to
2618 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2620 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2623 (emit_insn): New function.
2624 (md_assemble): Call it.
2625 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2627 (lituse_pending): New variable. Set by anything that generates a
2628 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2629 tested by code that might want to emit a LITUSE reloc.
2630 (emit_unaligned_io): New function. Currently calls md_assemble,
2631 but it should eventually be converted to generate the insn itself
2632 and call emit_insn directly.
2633 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2634 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2635 emit_bis_r): Likewise.
2636 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2637 (alpha_ip, label get_macro): Don't emit the final instruction if
2639 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2640 unaligned memory access macros.
2641 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2642 the value can't be resolved.
2644 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2646 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2647 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2648 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2650 (mips_force_relocation): New function.
2651 (md_apply_fix): Set fixP->fx_done appropriately.
2652 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to
2654 * config/tc-mips.h (TC_FORCE_RELOCATION): Define.
2655 (mips_force_relocation): Declare.
2656 (TC_HANDLE_FX_DONE): Define.
2658 Tue Mar 22 13:58:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2660 * config/tc-mips.c (enum mips_pic_level): New enum.
2661 (mips_pic): Change from int to enum mips_pic_level. Change all
2662 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2663 (load_address): Handle EMBEDDED_PIC.
2664 (macro): Handle EMBEDDED_PIC in all PIC cases.
2665 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2666 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2667 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2668 works). Do not permit -G with SVR4_PIC.
2669 (s_abicalls): Warn if -G was used, and force -G 0.
2670 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2671 anything but a.out, not just for ELF. For ECOFF, don't generate a
2672 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2674 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2676 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2678 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2679 parameters to avoid losing when compiling with HP CC.
2680 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2682 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2684 * Makefile.in (config-stamp): If `defs' is defined, emit a
2685 preprocessor directive to create a macro named by this value into
2686 config.new; don't explicitly go for BFD_ASSEMBLER.
2687 * configure.in: Define `defs', not `BFDDEF'. Set it to
2688 MANY_SEGMENTS for any obj-coffbfd target.
2689 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2690 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2692 (LOCAL_LOADLIBES): Deleted.
2693 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2694 * config/m88kcoff.mt (TDEFINES): Ditto.
2695 * config/ebmon29k.mt: Deleted.
2696 * config/h8300hds.mt: Deleted.
2697 * config/ic960coff.mt: Deleted.
2698 * config/sparc.mt: Deleted.
2699 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2700 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2701 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2702 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
2703 (TDEFINES): Don't define the coffbfd macros.

2706 (OBJS): Add $(TE_OBJS).
2708 * config/obj-coff.c (obj_pseudo_table): Supply "section"
2711 * write.c (set_symtab): Define only if BFD_ASSEMBLER.

2720 bfd_set_symtab is called.
2721 (dump_section_relocs): Note whether a symbol is a section symbol
2723 (adjust_reloc_syms): For now, always supply an absolute symbol for
2724 fixups without symbols but not yet `done'. Use section_symbol to
2725 get the symbol, instead of going directly for abs_symbol.
2726 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2727 reloc is not a section symbol and is not in the symbol table.
2728 (set_symtab): New function, broken out from write_object_file.
2729 Counts symbol table instead of relying on an earlier count.
2730 (write_object_file): Call set_symtab, but do it after potentially
2731 invoking the *_frob_file macros. Don't bother counting symbols.
2732 Call symbol_remove, instead of expanding it in place. Moved the
2733 conditionalized `object_file_size' declaration down to
2734 conditionalized block where it's used. When using the absolute
2735 symbol for a fixup without a symbol, set sy_used_in_reloc.
2736 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2737 the correct symbol for the absolute section.
2739 * subsegs.c (section_symbol): Use symbol_new instead of
2740 symbol_make, since we may want it to go into the symbol table.
2741 Make the new symbol have internal linkage. If
2742 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2743 symbol with the newly created GAS symbol.
2744 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2745 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2747 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
2749 * config/tc-sparc.c: Include subsegs.h.
2750 (in_signed_range): New function.
2752 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2753 (sparc_ip, label "immediate"): Reject constants for pcrel
2754 instructions only if the relocation type indicates a "call"
2755 instruction and the offset is within range of a "jmpl %g0". If
2756 it's not in range, use the absolute section symbol plus an offset.
2757 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2759 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2761 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2764 * configure.in: Eliminated all targets using obj-coff but not
2765 defining BFD_ASSEMBLER; I think all such targets that are
2766 supported will be matched by real CPU-OS combinations earlier in
2768 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2769 some comments about the dpx2 configuration, but left it disabled,
2770 since it couldn't be reached before.
2771 (target a29k-amd-ebmonold): Deleted.
2773 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2775 * config/tc-hppa.c (pa_import): Correctly handle importing of an
2776 already defined symbol.
2778 Wed Mar 16 17:11:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2780 * config/tc-mips.c (mips_ip): Only accept overly large values for
2781 the 'j' operand if there are no further alternatives for this
2784 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2785 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2786 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2788 * config/tc-mips.c (mips_align): Take new argument, label, and use
2789 it instead of global insn_label.
2790 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2791 call to mips_emit_delay and pass it to mips_align.
2793 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2795 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2797 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2798 argument to a .callinfo directive. Don't loop forever on errors.
2800 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2801 use pre-defined registers as arguments.
2803 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2805 * write.c (write_object_file): Check both S_IS_LOCAL and
2806 S_IS_EXTERNAL when deciding whether to discard a symbol.
2808 * config-gas.com: Scan Makefile.in, not version.c, for current
2809 version number. Delete all versions of temp files when finished
2810 with them. Create config.h.
2812 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2813 values to reduce number of lookups with S_GET_VALUE. Skip debug
2814 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2815 holger@botbso.rhein-main.de.)
2816 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER

4550 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4551 standard hpux include files to pick up various function decls.
4553 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4586 of interest to the linker. ENTRY/EXIT relocations for SOM are
4587 an example of marker relocations.
4588 * write.c (write_relocs): Instead of assuming size of a relocation
4589 is 4 bytes, pick up the size from relocation itself.

4617 BFD_RELOC_MIPS_GPREL. Added new case a.
4618 (set_at, load_register, macro): Changed calls to macro_build to
4619 pass new argument for i, j and o cases.
4620 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
4621 special handling when generating SVR4 PIC code.

4958 for keeping or rejecting configurations still under development;
4959 default is to assume production environment, and reject configs
4960 still being worked on. Mark Elf configurations (except sparc and
4961 i386) as developmental. Deleted cases matching some generic names
4962 in favor of more specific names. (E.g., when we get Alpha

4980 for functions only used within tc-hppa.c, likewise for structures,
4981 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4982 conditional code in a few small places.

4988 into a few places. Make all functions and variables which
4989 are only used within tc-hppa.c static. PARAMize all functions.
4990 Add comments to functions. Delete unused functions, variables,
4991 #defines, etc. Delete unused members within structures. Delete
4992 ldil;ble hacks -- it is believed they were installed to work
4993 around old gas bugs. Avoid using mixed case for local
4994 functions, variables, and structures. Fix formatting problems
4995 not found by GNU-indent. Add FIXME notices for things which
4996 should be worked on the near future. Delete lots of old
4997 useless (1.36 PA-SOM) code.

5076 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5078 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5079 ELF, since the ELF object format does not have these type of
5080 relocations. Change the abort into as as_bad and return
5081 BFD_RELOC_NONE to silence compiler warnings.
5082 (md_assemble): Keep track of the instruction size. Allow white
5083 space between the $ and the constant for compatibility with older

6093 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
6094 are also magic, and have special default flag settings.
6095 (obj_elf_frob_symbol): Since the return value from this function
6096 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6097 doesn't accomplish anything else.

6109 undefined_section for the return value.
6111 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6112 pseudo-op with a poc_handler field of NULL, ignore it and treat it
6113 as an instruction instead.

6129 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6130 case to set obj_format=elf. Must go before i386-*-sysv* case that
6131 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6132 *-*-solaris case, and move to before *-sysv* case that wants to

6159 * Extensive changes to permit symbols to contain any expression
6160 type and to delay the computation of the expression until the
6161 value is actually needed. This permits setting symbols to values
6162 calculated based on object code size. Expressions were changed to
6163 no longer be in a section, to stop the overloading of segment and
6164 expression type that previously occurred.
6166 * as.c (big_section, pass1_section, diff_section, absent_section):
6168 (expr_section): Added (used for dummy symbols which hold

6252 (previous_section, previous_subsection): New vars.
6253 (obj_elf_section): Save current place in case DWARF code wants us
6254 to pop back to it. Handle unquoted section name as well as quoted
6255 section name. Don't crash on invalid strings.
6256 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6259 * config/obj-elf.h: Don't include struc-symbol.h.

7568 dropping a space immediately following an identifier.
7569 * expr.c, write.c: Rewrote assert expressions to not use multiple
7570 lines; I don't think that can be done portably.
7571 * config/tc-mips.c (macro): Use $AT if target register is zero in
7572 load instruction, which it can be for a floating point load.

7646 prototypes for all static functions. Moved existing minimal
7647 debugging format support info #ifndef OBJ_ECOFF blocks.

7696 * make-gas.com: Find obstack.obj if it's not in the current
7698 * read.c (s_ignore): Don't declare is_end_of_line. It's
7699 redundant, and triggers a VMS gcc compiler bug.
7701 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7702 current segment as an argument. (Ignored in all cases but VMS.)
7703 All callers and definitions changed.

7757 constants are accepted, but symbolic values are not. GCC will not
7758 generate the latter currently.
7760 * frags.c (frag_init): New function.
7761 (zero_address_frag, bss_address_frag): Now initialized at run
7763 * as.c (main): Call frag_init.

8013 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8014 md_relax_table): Use default zero initialization.
8015 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8016 latter, instead of selecting with preprocessor conditionals.
8018 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8020 * configure.in: recognise all sparclite variants

8028 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8030 * expr.c (operand): If character other than comma or newline is a
8031 logical end-of-line character, use the newline case.
8032 From Eric Youngdale:
8033 (operand): Set X_add_number field for floating-point numbers.
8034 (operand): Treat zero byte as end-of-operand.
8036 * configure.in (per-target): Look for with_bfd_assembler option.
8037 For now, only accept "no", until the merge is done.
8039 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8040 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8041 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8042 * read.c: Finish conversion to S_* macros in the VMS only
8043 parts of the program. Add "const" modifier to hex_value.

8046 * expr.c: Add "const" modifier to hex_value.
8047 * symbols.c: Finish conversion to S_* macros in the VMS only
8048 parts of the program. Add "const" modifier to
8049 md_[long,short]_jump_size. Remove declaration of const_flag
8050 (which will be declared in obj-vms.h).
8051 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8052 Fix arguments to VMS_write_object_file.
8053 * config-gas.com: New file. Script for VMS systems to set up the
8054 configuration to build gas for VMS, and create config.status.
8055 * make-gas.com: Redone to work with new scheme.
8056 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8058 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8059 will swap bytes if needed on a big endian system. Use throughout
8061 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8062 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8063 types of malformed stabs. Change parsing algorithm so that we are
8064 more certain of having all of the information that we need on hand.
8065 * obj-vms.c (final_forward_reference): New function, used to help
8066 resolve the data types of as many struct elements as possible
8067 when some part of the struct is not fully defined by the compiler.

8070 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8071 as symbols as well in the object file. Look for external functions
8072 that start with "__vt.", and turn them into variables, since the
8073 g++ compiler is incapable of doing this.
8074 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8076 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8077 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8078 have the name of the source file yet.
8079 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8081 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8083 * read.c (s_data): Always use "data_section", since it'll map to
8084 SEG_DATA or SEG_E1 if needed.
8085 (s_lcomm): Likewise with bss_section.
8086 (s_fill): Use memset, not bzero.
8088 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8110 (big_section, reg_section, pass1_section, diff_section,
8111 absent_section, text_section, data_section, bss_section): If
8112 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8113 mapping to segT enum values.
8114 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8115 if these are used or defined, if BFD_ASSEMBLER.
8116 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8117 subseg_new split into two functions.
8118 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8120 * as.h (volatile): Don't define if already defined.
8121 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8123 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8124 declare with format attribute for -Wformat checking.
8126 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8128 * app.c, config/tc-*.c: Don't include read.h, since it is already
8131 * These are based on patches from Minh Tran-le
8132 <mtranle@paris.intellicorp.com>.
8133 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8134 obj_format coffbfd and gas_target i386coff for target.
8135 (i[34]86-*-isc*): New host (uses sysv).
8136 * config/i386aix.mt: Removed (no longer used).
8137 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8139 (LDFLAGS): Added, defined as -shlib.
8140 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8141 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8142 (DOT_LABEL_PREFIX): Define.
8143 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8144 name rather than L0\001.
8145 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8147 * symbols.c, symbols.h (local_bss_counter): Removed.

8156 (size_section): Restored sanity check.
8157 (do_relocs_for): Base section address on s_paddr rather than
8158 computing it. Adjust a29k R_IHIHALF special case to account for
8159 section paddr (used to require paddr to be zero). If there are no
8160 reclos, set s_relptr to 0. Set relocation size in object_headers.
8161 (fill_section): Always set s_vaddr here, removing
8162 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8163 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8164 Set STYP_INFO for .comment.

8168 H_{SET,GET}_* macros.
8169 (do_linenos_for): Set lineno size in object_headers.
8170 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8171 set s_vaddr here. If string_byte_count remains 4, set it back to
8172 0, and only write strings out if there are some. Call
8173 fill_section before do_relocs_for and do_linenos_for.
8174 (obj_coff_section): Handle optional quoted second argument giving
8175 section characteristics.
8176 (obj_coff_bss): Added to handle .bss.
8177 (obj_coff_ident): Added to handle .ident (puts string in .comment

8197 (do_scrub_next_char): For \", return " not '.
8198 (symbol_chars): Now const.
8200 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8201 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8203 * config/obj-coff.h: Don't use #elif.
8205 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8206 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8232 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8233 using ZERO_BASED_SEGMENTS.
8234 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8235 never set segment address for SEG_E2 (.bss) and don't write out
8236 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8237 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8238 definitions, and don't merge tags with non-tags. Check for .bf
8239 rather than just checking whether the second character is b and
8240 the third character is f.
8241 (obj_coff_val): gcc can generate values which we don't handle
8242 correctly; discard information for now, since it only affects the
8243 debugging information.
8244 (tag_find_or_name): Don't insert tags in the symbol table.
8245 (yank_symbols): Don't merge labels.
8246 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8449 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8450 so widening works consistently.
8452 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8454 * version.c: Put conditional "const" before version_string, not
8455 before dummy function for VMS. Now version 1.91.03.
8457 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8458 printed rep of null character.
8460 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
8462 * obj-coffbfd.c (write_object_file): check return value of
8465 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8467 * Support for i386-sysv.
8468 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8469 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8470 be used to set them all to zero as was done before.
8471 (fill_section): segment addresses now set in write_object_file.
8472 (fill_section): Don't set STYP_NOLOAD for .bss section.
8473 (fixup_segment): 386 uses strange common symbol format.
8474 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8475 compatibility with SVR3.2 linker.
8476 * configure.in: i386-sysv and i386-sco use coffbfd.

8488 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8489 support for C source listings. (obj_coff_endef): look in the right
8490 part of the symbol for the symbol name
8492 * tc-m68k.c (get_num): make it work for all segments, not just the
8495 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

8506 * tc-z8k.c: lots of bug fixes
8508 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8510 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8511 #elif, since it is not supported by old compilers.
8512 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8513 couple of expressions in tc-m68k.c.
8515 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8517 * read.c (cons): If NO_RELOC is defined, use it.
8519 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8521 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8523 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8524 local labels to start with a .) and set REGISTER_PREFIX to %.
8525 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8543 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8544 sections starting from zero, rather than making them consecutive.
8545 This makes subsequent reloc calculations easier, esp if the object
8546 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8547 allocate lcomm in .data rather than in .bss. It seems that some
8548 tools can't cope with a non-zero sized bss before linkage.
8550 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8552 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8571 * Makefile.in (install): if $(tooldir) exists, install as in
8574 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8576 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8577 .word is < -32768 or > 32767. The -J flag causes the error to be
8578 ignored. This is to catch over-sized switches generated by gcc on
8579 systems which don't support the broken .word hack.
8580 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8581 write.c (fixup_segment): check for signed .word overflow if
8582 WARN_SIGNED_OVERFLOW_WORD.

8601 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8603 * input-scrub.c (input_scrub_push): call input_file_begin, not
8605 messages.c (as_perror): print ": " between the passed in error and
8606 the strerror, like perror does.
8608 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8611 From Steve Chamberlain:
8612 Makefile.in: Handle m68*-*-coff*.
8613 read.c, read.h: add mult argument to s_space
8615 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8616 Motorola and MIT syntax; gas can now assemble either type of
8618 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8625 (fixup_segment) set fx_subsy to 0.
8626 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8628 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8631 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8633 * Makefile.in (LIBS): Include opcode library.

8658 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8660 * config/tc-m68k.c (init_table): Now const. Always include 68851
8661 data, so that "bc" is available to 68040 cache instructions.
8662 Added "tt0", "tt1", and 68ec030 variants.
8663 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8664 (enum _register): Added TT0, TT1.
8665 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8666 line number correctly in "internal error" messages. Don't print
8667 architecture-mismatch message for operand errors.
8669 From Colin Smith (colin@wrs.com):
8670 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8671 than install_operand.

8692 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8693 has already been formatted (but may still contain %-characters).
8696 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8698 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8699 written with indirection on the last two operands, which can be
8700 either data or address registers. Added a new operand type 'r'
8701 which accepts either register type. Added '(' to notend stuff in
8702 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8721 their not having symbols associated.
8723 * tc-i960.c (norelax, instrument_branches): Default initializer is

8749 being used with args swapped, causing occasional lossage when
8750 refilling buffers after an include file.

8809 ancient or broken compilers.
8811 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
8812 processor/opcode mismatch, so reword the error message.

8923 Thu May 14 17:22:48 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8925 * doc/Makefile.in: use m4 rather than gm4.
8927 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8929 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
8930 calc the base of relocs correctly.
8931 * tc-a29k.c (parse_operand): allow expressions to be in any section.
8933 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
8935 * as.c, write.c: use -K rather than -k for the broken word warning
8938 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
8940 * Makefile.in: do not print recursion lines.
8942 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8944 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
8946 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8948 * write.c (write_object_file): For b.out format, round up section
8949 start addresses to match required alignment.
8951 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8953 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8954 where gcc looks for it.
8956 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8958 * Makefile.in: Changed some lines to be less confusing for some
8961 * input-file.c: Conditionalize on _IOFBF, not VMS.
8963 * read.c, write.c: Change a series of ifdef/elif to
8964 ifdef/else/ifdef etc.
8966 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
8968 * symbols.c (fb_label_init): fix sizeof to memset.
8970 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
8972 * Makefile.in: install the man page.
8974 * Makefile.in: pass down MAKEINFO explicitly on info.
8976 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
8978 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8980 * flonum-const.c: renamed flonum-konst.c to stop dos name
8983 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8985 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8986 tc-m68k.h to te-sun3.h.
8988 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8990 * configure.in: vxworks68 gets te-sun3.h.
8992 * expr.c: remove limitation that local_labels_dollar or
8993 local_labels_fb must be < 10.
8995 * symbols.c: remove local_labels_dollar, replace with a function
8996 interface for a sparse array. All users adjusted.
8998 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9000 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9002 * doc/Makefile.in: commented out line for building as-all.texinfo.
9005 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9007 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9009 * Makefile.in: added check target.
9011 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9013 * Makefile.in: added tooldir and program_prefix.
9015 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9017 * write.{c,h} (fix_new): Make these declarations consistent.
9019 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9021 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9024 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9026 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9028 * expr.c (operand): if can't work out what sort of operand it is,
9029 then look through FLT_CHARS for a hint.
9031 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9033 * Makefile.in, configure.in: removed traces of namesubdir,
9034 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9035 copyrights to '92, changed some from Cygnus to FSF.
9037 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9038 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9039 copyrights to '92, changed some from Cygnus to FSF.
9041 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9043 * expr.c: If an expression is single comma, then return with
9044 SEG_ABSENT rather than an error - since the sparc front end does
9045 really strange things with things like fbge,a
9047 * as.h: include bfd.h if using many sections
9048 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9049 local labels didn't work.
9050 * listing.c (list_symbol_table): don't core dump when there's no
9052 * write.c, write.h: call fix_new with the right number of args on
9054 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9057 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9059 * app.c: MRI compatibility - allow single quote to start a string.
9060 * as.c: fix typo recently introduced.
9061 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9062 * expr.c: Much rewriting, to accomodate MRI syntax for
9063 expressions. Also easier to read now.
9064 * listing.c: Put back defuns
9065 * read.c: modified to accept MRI syntax, put back listing pseudo
9066 ops so that an assembler built with NO_LISTING ignores list ops
9068 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9069 machine is a SPARC or a 29K.
9070 * config/obj-aout.c: added s_sect pseudo op
9071 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9072 fill in the timestamp.
9073 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9074 anymore, define all the relocs which the tc-<x> bit will use so we
9075 can translate from them to the coff types.
9076 * config/tc-a29k.c: reloc_type isn't ane enum any more
9077 * config/tc-m68k.c: Added NO_RELOC definition.
9079 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9081 * Makefile.in: put header files before C source for TAGS; remove
9082 references to non-existent syscalls.h.
9084 * read.c, write.c subsegs.c: back out the .bss changes.
9086 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9088 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9092 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9094 * symbols.c (local_label_name): symbols now start with ^A.
9096 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9097 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9098 generate these sections. .align: will use NOP_OPCODE or 0
9099 for padding. This is just for being nice to the
9102 * expr.c (operand): changed to generate local label "\001L0"
9103 starting with a ^A so that it is recognized as a local label.
9105 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9107 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9108 i/o opcodes - inb, inw, outb and outw. string manipulation with
9109 att syntax - scmp, slod, smov, ssca, ssto.
9111 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9112 to just after .file .
9114 In obj_crawl_symbol_chain() where it tries to put the external
9115 symbols apart, with the condition:
9116 (!S_IS_DEFINED(symbolP) &&
9117 !S_IS_DEBUG(symbolP) &&
9118 !SF_GET_STATICS(symbolP))
9119 it was moving too many symbols out. So I switch it back to the
9121 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9123 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9124 so that we don't use the F_RELFLG which make the linker complain
9125 that somebody has stripped the relocation info.
9127 Also, the AIX ld program require that the relocation table
9128 is sorted by r_vaddr like the standard ATT assembler does.
9130 [he also changed the sizeof(struct ...)'s into the coff
9131 style FOOSZ macros. I'm not sure this is right, but I can't
9132 remember why. xoxorich.]
9134 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9136 * Makefile.in, configure.in, doc: use the doc. Build it, install
9139 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9141 * read.c: white space and comments only.
9143 * configure.in: use the new atof-ns32.c for ns32k.
9145 * write.c: comment change only.
9147 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9148 aren't yet integrated.
9150 * tc-i860.[hc]: blew off the dust. Something must still be done
9151 about conflicting relocation types.
9153 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9156 * tc-i960.c, tc-sparc.c: white space and comments only.
9158 * tc-a29k.h: delete duplicate macro definition.
9160 * new file atof-ns32k.c copied from hack's last unreleased gas.
9162 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9164 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9167 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9168 ChangeLog's prior to this are sketchy at best. I have logs.
9169 They just aren't ChangeLogs.
9176 version-control: never
