512 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
514 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
515 change; it breaks the rs6000 support, and doesn't seem to be

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

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

560 expression pointer to the symbol structure, used for `size'
561 expressions that couldn't be reduced to constants when initially
563 (elf_frob_symbol): Declare.
564 (obj_frob_symbol): Call elf_frob_symbol always, rather than
565 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.
566 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
568 (obj_elf_size): Deleted unused code. If size is non-reducible

591 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
593 (obj_frob_file): New macro.
595 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

623 (diststuff): New target; builds DISTSTUFF.
624 (realclean): Separate target, depend on clean and distclean, then
626 * make-gas.com: Deleted.
628 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New

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

657 DEBUG5 is defined, print out each fixup before and after
659 (fixup_segment): If DEBUG5 is defined, print out each fixup before
660 and after processing.

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

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

694 (indent_level): No longer static.
695 (print_symbol_value_1): Don't print frag address if it matches
696 zero_address_frag. Don't print "resolving" if already resolved.
697 Print segment name. Don't call print_expr_1 on an undefined
699 (print_expr_1): Fix whitespace before printing X_add_number.
701 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
702 not symbol_new, for symbols holding expression values.
703 * expr.h (make_expr_symbol): Move declaration here.
704 * write.c (fix_new_exp): Handle O_add by creating an
705 expression-valued symbol, and calling fix_new_exp recursively.
706 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
707 undefined symbol and a constant, fold the constant into the fixup,
708 and refer to the undefined symbol directly. Then process the
709 fixup again from scratch.
710 (write_object_file): Before calling adjust_reloc_syms, make a pass
711 through the symbol list trying to resolve values.
713 * write.c (print_fixup): New routine, for debugging.
714 (write_relocs): Call bfd_install_relocation. Deleted various
715 hacks for working around problems with bfd_perform_relocation.

719 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
721 * Makefile.in (gasp.o): Depends upon config.h.
723 * config/tc-mips.c: Include subsegs.h.
724 (md_apply_fix): If an unconditional b or bal overflows, and we are
725 not assembling PIC code, replace it with a j or jal.
727 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
728 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

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

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

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

781 * config/ho-*.h: Now-unused files deleted.
783 * symbols.c (copy_symbol_attributes): New function. Copies BFD
784 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
785 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
786 zero. Don't call obj_frob_forward_symbol.
787 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

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

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

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

847 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
848 many others): new macros; values obtained from "DSTRECRDS.SDL".
849 * config/obj-vms.h (various): use them.
850 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
851 representation (only enum bitfields can avoid being bitstrings).
852 (bitfield_suffix, setup_basic_type): new routines.
853 (VMS_typedef_parse): use them. Now recognize bitfields of all
854 integral types, not just type `int'. Caveat: the representation
855 used for bitfields still does not work for objects placed in
856 registers, and gcc's optimizer sometimes puts small structs there.
858 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
860 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
862 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
863 (tc_frob_label): define this to call vms_check_for_special_label,
864 and declare the latter.
865 * config/obj-vms.c (vax_g_doubles): declare this file-scope
867 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
868 (vms_check_for_special_label): new routine (tc_frob_label).
869 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
870 and `gcc2_compiled.' labels; they won't reach here any more.
871 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
872 double', use `vax_g_doubles' flag to select type of double.
873 (VMS_write_object_file) [traceback setup]: don't pass symbols
874 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
875 and TBT_Routine_End functions.
877 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
879 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
880 S_GET_VALUE() to avoid many repeated function calls.
881 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
882 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
883 gets requested. [All the HACK_DEC_C_STARTUP code appears to
884 be obsolete; gcc does it automatically for vms target. It's
885 also misnamed, because it is for the "VAX C" run-time library,
886 not the newer "DEC C" one which has much different startup code.]
887 {various}: use `S_SET_xxx(symbol,new_value)' rather than
888 `S_GET_xxx(symbol) = new_value'.
890 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
892 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
893 not &bfd_abs_section.

897 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
899 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
901 * expr.c (expr): Don't reduce the difference of two symbols in the
902 same frag if the symbols are not in normal sections.
904 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
905 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
906 (obj_attach_unwind_info): Do not define. Not needed anymore.
907 * config/tc-hppa.c: Delete whitespace at EOL.
908 (struct hppa_fix_struct): Delete fx_unwind field and all references.
909 (fix_new_hppa): Last arg is now a pointer to an int. Do not
910 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
911 fixups, store 32bits of unwind information in the fx_addnumber
913 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
914 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
915 pointer to 32 bits of unwind info.
916 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
917 pointer to the dummy symbol; set the addend field to fx_addnumber.
918 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
919 rather than &bfd_XXX_section.
921 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
923 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
924 value by one; discard adjustments previously being made. From
927 VMS- and Vax-related changes from Pat Rankin:
928 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
929 * vmsconf.sh: no longer have make-gas.com echo text about needing
930 to modify the gcc-vms driver when intending to use with gcc 1.x.
931 * as.c (parse_options): suppress 'v' from std_short_options and
932 eliminate VMS-specific conditional initialization;
933 [default case]: check for '-v' if md_parse_options doesn't recognize
935 [default case, #if VMS]: check for filename argument when '-v' seen;
937 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
938 for O_big literal operands (double floats and long long ints);
939 [VMS, md_shortopts]: add second colon after 'v';
940 (md_parse_options) [VMS, case 'v']: check for argument, so
941 caller can handle `-v' w/o arg.

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

954 * flonum-konst.c: Change preprocessor tests of HO_VMS to just VMS.
955 * hex-value.c: Ditto.
956 * config/obj-vms.c: Ditto.
958 * config/tc-sparc.c (sparc_ip): Replace as_bad/exit sequence with
960 * config/tc-i860.c (i860_ip): Ditto.

1916 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
1918 * Makefile.in (check): Delete as.new dependency, so that

1937 * read.c (emit_expr): Use memset to zero out memory, rather than
1938 going through md_number_to_chars. This permits handling symbolic

1992 (control_regs): New pointer.
1993 (m68k_ip): Use control_regs instead of testing CPU every time.

2311 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
2313 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
2314 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
2315 R_DIR16, and R_DIR32 relocs.

2424 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2427 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2429 * expr.c (operand): Try to parse "0f" and "0b" sequences as

2431 work, treat them as local labels.
2433 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2434 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2436 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2438 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2439 source files from other directories into objects in the current
2440 directory, and specify PSECT attributes explicitly to linker.
2441 Also added missing label.
2442 * Makefile.in (stamp-mk.com): Reference new variable

2458 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2459 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2460 argument, the reloc type.
2461 (load_register): Pass reloc type to macro_build for 'u'.
2462 (macro): Likewise. For M_LA_AB permit a difference expression
2463 when generating embedded PIC code between an arbitrary symbol and
2464 a symbol in the .text section.
2465 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

2474 * subsegs.c (subsegs_begin): Call memset with args in the correct
2476 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2477 to NULL instead of 0.

2481 * config/tc-hppa.c (pa_procend): Handle case where label was
2482 defined after the .proc directive.
2484 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2485 procend for a procedure without a name.

2506 (hppa_tc_symbol): Likewise.
2508 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2509 elf_tc_make_sections stuff. It was there to support PA braindamage
2510 which has been fixed, and in the case of elf_tc_make_sections is
2511 redundant with elf_tc_final_processing.
2513 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2515 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2530 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2531 don't spew remainder of input file in error message.
2532 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2533 message with reloc type and try to process remainder of file.
2535 * doc/Makefile.in (install-info-as, install-info-gasp): New
2536 targets, now explicitly checking $(srcdir) for info files.
2537 (install-info): Depend on both of them; do nothing more.

2541 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2543 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2545 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2546 flag rather than signedp field. Only permit extended range if
2547 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2548 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2550 * config/tc-ppc.c (ppc_size): New static variable.
2551 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2552 (md_begin): If an instruction has a size specific flag set, only
2553 add it if we are assembling that size.
2555 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2557 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2558 cross section PC relative relocs right for COFF and ELF.
2560 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2562 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2563 (OBJ_PROCESS_STAB): Don't define.
2565 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2567 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2568 the type of symbol set symbols which happen to be in the absolute
2569 or undefined section.
2571 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2573 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2574 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2575 and -many (all architectures).
2577 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2579 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2580 involving a function symbol which is not a plabel to zero.
2581 (md_apply_fix): Never pass a function symbol to field_adjust.
2583 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2585 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2586 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2588 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2589 branch with an instruction that uses $at, in case the branch is
2591 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2592 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2593 to make it pcrel_offset.
2594 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2595 reloc->address; another gruesome hack to get gas reloc handling to
2598 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2600 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2603 (emit_insn): New function.
2604 (md_assemble): Call it.
2605 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2607 (lituse_pending): New variable. Set by anything that generates a
2608 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2609 tested by code that might want to emit a LITUSE reloc.
2610 (emit_unaligned_io): New function. Currently calls md_assemble,
2611 but it should eventually be converted to generate the insn itself
2612 and call emit_insn directly.
2613 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2614 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2615 emit_bis_r): Likewise.
2616 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2617 (alpha_ip, label get_macro): Don't emit the final instruction if
2619 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2620 unaligned memory access macros.
2621 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2622 the value can't be resolved.
2624 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2626 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2627 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2628 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2630 (mips_force_relocation): New function.
2631 (md_apply_fix): Set fixP->fx_done appropriately.
2632 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2640 * config/tc-mips.c (enum mips_pic_level): New enum.
2641 (mips_pic): Change from int to enum mips_pic_level. Change all
2642 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2643 (load_address): Handle EMBEDDED_PIC.
2644 (macro): Handle EMBEDDED_PIC in all PIC cases.
2645 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2646 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2647 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2648 works). Do not permit -G with SVR4_PIC.
2649 (s_abicalls): Warn if -G was used, and force -G 0.
2650 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2651 anything but a.out, not just for ELF. For ECOFF, don't generate a
2652 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2654 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2656 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2658 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2659 parameters to avoid losing when compiling with HP CC.
2660 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2662 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2664 * Makefile.in (config-stamp): If `defs' is defined, emit a
2665 preprocessor directive to create a macro named by this value into
2666 config.new; don't explicitly go for BFD_ASSEMBLER.
2667 * configure.in: Define `defs', not `BFDDEF'. Set it to
2668 MANY_SEGMENTS for any obj-coffbfd target.
2669 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2670 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2672 (LOCAL_LOADLIBES): Deleted.
2673 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2674 * config/m88kcoff.mt (TDEFINES): Ditto.
2675 * config/ebmon29k.mt: Deleted.
2676 * config/h8300hds.mt: Deleted.
2677 * config/ic960coff.mt: Deleted.
2678 * config/sparc.mt: Deleted.
2679 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2680 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2681 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2682 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

2700 bfd_set_symtab is called.
2701 (dump_section_relocs): Note whether a symbol is a section symbol
2703 (adjust_reloc_syms): For now, always supply an absolute symbol for
2704 fixups without symbols but not yet `done'. Use section_symbol to
2705 get the symbol, instead of going directly for abs_symbol.
2706 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2707 reloc is not a section symbol and is not in the symbol table.
2708 (set_symtab): New function, broken out from write_object_file.
2709 Counts symbol table instead of relying on an earlier count.
2710 (write_object_file): Call set_symtab, but do it after potentially
2711 invoking the *_frob_file macros. Don't bother counting symbols.
2712 Call symbol_remove, instead of expanding it in place. Moved the
2713 conditionalized `object_file_size' declaration down to
2714 conditionalized block where it's used. When using the absolute
2715 symbol for a fixup without a symbol, set sy_used_in_reloc.
2716 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2717 the correct symbol for the absolute section.
2719 * subsegs.c (section_symbol): Use symbol_new instead of
2720 symbol_make, since we may want it to go into the symbol table.
2721 Make the new symbol have internal linkage. If
2722 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2723 symbol with the newly created GAS symbol.
2724 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2725 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2727 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
2729 * config/tc-sparc.c: Include subsegs.h.
2730 (in_signed_range): New function.
2732 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2733 (sparc_ip, label "immediate"): Reject constants for pcrel
2734 instructions only if the relocation type indicates a "call"
2735 instruction and the offset is within range of a "jmpl %g0". If
2736 it's not in range, use the absolute section symbol plus an offset.
2737 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2739 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2741 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2744 * configure.in: Eliminated all targets using obj-coff but not
2745 defining BFD_ASSEMBLER; I think all such targets that are
2746 supported will be matched by real CPU-OS combinations earlier in
2748 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2749 some comments about the dpx2 configuration, but left it disabled,
2750 since it couldn't be reached before.
2751 (target a29k-amd-ebmonold): Deleted.
2753 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2755 * config/tc-hppa.c (pa_import): Correctly handle importing of an
2756 already defined symbol.

2760 * config/tc-mips.c (mips_ip): Only accept overly large values for
2761 the 'j' operand if there are no further alternatives for this
2764 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2765 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2766 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2768 * config/tc-mips.c (mips_align): Take new argument, label, and use
2769 it instead of global insn_label.
2770 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2771 call to mips_emit_delay and pass it to mips_align.
2773 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2775 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2777 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2778 argument to a .callinfo directive. Don't loop forever on errors.
2780 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2781 use pre-defined registers as arguments.
2783 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2785 * write.c (write_object_file): Check both S_IS_LOCAL and
2786 S_IS_EXTERNAL when deciding whether to discard a symbol.
2788 * config-gas.com: Scan Makefile.in, not version.c, for current
2789 version number. Delete all versions of temp files when finished
2790 with them. Create config.h.
2792 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2793 values to reduce number of lookups with S_GET_VALUE. Skip debug
2794 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2795 holger@botbso.rhein-main.de.)
2796 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2797 field. (Also from Holger Teutsch.) Watch for a would-be register
2798 mask that spans frags.
2800 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2801 this_base, not line_base. (Patch from Andreas Arens,
2802 ari@obelix.av.rwth-aachen.de.)
2804 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2805 look local if they're exported or undefined. Used to be done for
2808 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2809 Get it from the looked-up symbol, instead of using the string from
2810 the input stream, which is no longer null-terminated.
2811 (LEX_PCT): New macro, defaults to 0.
2812 (lex_type): Use it for `%'.
2814 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2815 (vip_op): Now static, and returns void. Callers changed. Added
2817 (vip): Ditto. Call as_fatal directly if a program bug is
2819 (op_hash): Let default initialization suffice.
2821 * Makefile.in (literal.o): Provide dependencies.
2823 * configure.in: Set new makefile variable OPCODES_LIB.

4449 Delete dead code. Simplify.
4450 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4451 applied are in range. Use bfd_put_32 rather than inserting each

4527 empty string case like the HP assembler -- assume a value of
4530 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4531 standard hpux include files to pick up various function decls.
4533 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4547 descriptor information to the BFD symbol.
4548 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4566 of interest to the linker. ENTRY/EXIT relocations for SOM are
4567 an example of marker relocations.
4568 * write.c (write_relocs): Instead of assuming size of a relocation
4569 is 4 bytes, pick up the size from relocation itself.

4599 pass new argument for i, j and o cases.
4600 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
4601 special handling when generating SVR4 PIC code.

4673 (md_begin): Change into the (possibly modified) text_section.
4674 (pa_parse_space_stmt): Create a new segment/space if create_flag
4675 is true, and the space name is not one of the two predefined spaces.

4821 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4822 the table, require that the one without bit 0x1000000 set come

4933 OPTIONAL_REGISTER_PREFIX if either is already defined.
4935 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4937 * configure.in: Set bfd_gas for all sparc targets. Added facility
4938 for keeping or rejecting configurations still under development;
4939 default is to assume production environment, and reject configs
4940 still being worked on. Mark Elf configurations (except sparc and
4941 i386) as developmental. Deleted cases matching some generic names
4942 in favor of more specific names. (E.g., when we get Alpha

4959 through inclusion of tc-hppa.h. Delete all forward declarations
4960 for functions only used within tc-hppa.c, likewise for structures,
4961 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4962 conditional code in a few small places.
4964 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4965 structures, global variables, forward declarations together.

4967 conditional code -- try to group conditional code together
4968 into a few places. Make all functions and variables which
4969 are only used within tc-hppa.c static. PARAMize all functions.
4970 Add comments to functions. Delete unused functions, variables,
4971 #defines, etc. Delete unused members within structures. Delete
4972 ldil;ble hacks -- it is believed they were installed to work
4973 around old gas bugs. Avoid using mixed case for local
4974 functions, variables, and structures. Fix formatting problems
4975 not found by GNU-indent. Add FIXME notices for things which
4976 should be worked on the near future. Delete lots of old
4977 useless (1.36 PA-SOM) code.
4979 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4980 field of the fixS structure. Needed to build unwind

5056 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5058 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5059 ELF, since the ELF object format does not have these type of
5060 relocations. Change the abort into as as_bad and return
5061 BFD_RELOC_NONE to silence compiler warnings.
5062 (md_assemble): Keep track of the instruction size. Allow white
5063 space between the $ and the constant for compatibility with older
5064 gases and other assemblers.

6071 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6073 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
6074 are also magic, and have special default flag settings.
6075 (obj_elf_frob_symbol): Since the return value from this function
6076 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6077 doesn't accomplish anything else.

6089 undefined_section for the return value.
6091 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6092 pseudo-op with a poc_handler field of NULL, ignore it and treat it

6109 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6110 case to set obj_format=elf. Must go before i386-*-sysv* case that
6111 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6112 *-*-solaris case, and move to before *-sysv* case that wants to
6113 set obj_format to coff.

6139 * Extensive changes to permit symbols to contain any expression
6140 type and to delay the computation of the expression until the
6141 value is actually needed. This permits setting symbols to values
6142 calculated based on object code size. Expressions were changed to
6143 no longer be in a section, to stop the overloading of segment and
6144 expression type that previously occurred.
6146 * as.c (big_section, pass1_section, diff_section, absent_section):
6148 (expr_section): Added (used for dummy symbols which hold

6232 (previous_section, previous_subsection): New vars.
6233 (obj_elf_section): Save current place in case DWARF code wants us
6234 to pop back to it. Handle unquoted section name as well as quoted
6235 section name. Don't crash on invalid strings.
6236 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6239 * config/obj-elf.h: Don't include struc-symbol.h.

6348 sy_resolved and sy_resolving single bit fields.
6349 * symbols.c (symbol_new): Don't initialize sy_forward field.

7548 dropping a space immediately following an identifier.
7549 * expr.c, write.c: Rewrote assert expressions to not use multiple
7550 lines; I don't think that can be done portably.
7551 * config/tc-mips.c (macro): Use $AT if target register is zero in
7552 load instruction, which it can be for a floating point load.

7626 prototypes for all static functions. Moved existing minimal
7627 debugging format support info #ifndef OBJ_ECOFF blocks.

7676 * make-gas.com: Find obstack.obj if it's not in the current
7678 * read.c (s_ignore): Don't declare is_end_of_line. It's
7679 redundant, and triggers a VMS gcc compiler bug.
7681 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7682 current segment as an argument. (Ignored in all cases but VMS.)
7683 All callers and definitions changed.

7737 constants are accepted, but symbolic values are not. GCC will not
7738 generate the latter currently.
7740 * frags.c (frag_init): New function.
7741 (zero_address_frag, bss_address_frag): Now initialized at run
7743 * as.c (main): Call frag_init.

7981 (tc_aout_fix_to_chars): Array nbytes_r_length is now const.
7983 * config/tc-m68k.h (TC_COUNT_RELOC): Don't emit reloc if only
7984 offset field is set.
7986 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7988 * config/tc-sparc.c (sparc_ip): For %uhi and %ulo, if not

7993 * config/tc-sparc.c (architecture_requested, warn_on_bump,
7994 md_relax_table): Use default zero initialization.
7995 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
7996 latter, instead of selecting with preprocessor conditionals.
7998 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8000 * configure.in: recognise all sparclite variants
8002 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8008 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8010 * expr.c (operand): If character other than comma or newline is a
8011 logical end-of-line character, use the newline case.
8012 From Eric Youngdale:
8013 (operand): Set X_add_number field for floating-point numbers.
8014 (operand): Treat zero byte as end-of-operand.
8016 * configure.in (per-target): Look for with_bfd_assembler option.
8017 For now, only accept "no", until the merge is done.
8019 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8020 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8021 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8022 * read.c: Finish conversion to S_* macros in the VMS only
8023 parts of the program. Add "const" modifier to hex_value.
8024 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8026 * expr.c: Add "const" modifier to hex_value.
8027 * symbols.c: Finish conversion to S_* macros in the VMS only
8028 parts of the program. Add "const" modifier to
8029 md_[long,short]_jump_size. Remove declaration of const_flag
8030 (which will be declared in obj-vms.h).
8031 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8032 Fix arguments to VMS_write_object_file.
8033 * config-gas.com: New file. Script for VMS systems to set up the
8034 configuration to build gas for VMS, and create config.status.
8035 * make-gas.com: Redone to work with new scheme.
8036 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8038 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8039 will swap bytes if needed on a big endian system. Use throughout
8041 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8042 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8043 types of malformed stabs. Change parsing algorithm so that we are
8044 more certain of having all of the information that we need on hand.
8045 * obj-vms.c (final_forward_reference): New function, used to help
8046 resolve the data types of as many struct elements as possible
8047 when some part of the struct is not fully defined by the compiler.
8048 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8050 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8051 as symbols as well in the object file. Look for external functions
8052 that start with "__vt.", and turn them into variables, since the
8053 g++ compiler is incapable of doing this.
8054 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8056 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8057 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8058 have the name of the source file yet.
8059 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8061 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8063 * read.c (s_data): Always use "data_section", since it'll map to
8064 SEG_DATA or SEG_E1 if needed.
8065 (s_lcomm): Likewise with bss_section.
8066 (s_fill): Use memset, not bzero.
8068 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8089 (section_alignment): Declare only if not BFD_ASSEMBLER.
8090 (big_section, reg_section, pass1_section, diff_section,
8091 absent_section, text_section, data_section, bss_section): If
8092 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8093 mapping to segT enum values.
8094 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8095 if these are used or defined, if BFD_ASSEMBLER.
8096 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8097 subseg_new split into two functions.
8098 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8100 * as.h (volatile): Don't define if already defined.
8101 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8103 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8104 declare with format attribute for -Wformat checking.
8106 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8108 * app.c, config/tc-*.c: Don't include read.h, since it is already
8111 * These are based on patches from Minh Tran-le
8112 <mtranle@paris.intellicorp.com>.
8113 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8114 obj_format coffbfd and gas_target i386coff for target.
8115 (i[34]86-*-isc*): New host (uses sysv).
8116 * config/i386aix.mt: Removed (no longer used).
8117 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8119 (LDFLAGS): Added, defined as -shlib.
8120 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8121 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8122 (DOT_LABEL_PREFIX): Define.
8123 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8124 name rather than L0\001.
8125 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8127 * symbols.c, symbols.h (local_bss_counter): Removed.
8128 * write.c (write_object_file): bss no longer uses
8129 local_bss_counter. Pass correct data and bss size to
8130 VMS_write_object_file.

8136 (size_section): Restored sanity check.
8137 (do_relocs_for): Base section address on s_paddr rather than
8138 computing it. Adjust a29k R_IHIHALF special case to account for
8139 section paddr (used to require paddr to be zero). If there are no
8140 reclos, set s_relptr to 0. Set relocation size in object_headers.
8141 (fill_section): Always set s_vaddr here, removing
8142 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8143 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8144 Set STYP_INFO for .comment.
8145 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8146 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8148 H_{SET,GET}_* macros.
8149 (do_linenos_for): Set lineno size in object_headers.
8150 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8151 set s_vaddr here. If string_byte_count remains 4, set it back to
8152 0, and only write strings out if there are some. Call
8153 fill_section before do_relocs_for and do_linenos_for.
8154 (obj_coff_section): Handle optional quoted second argument giving
8155 section characteristics.
8156 (obj_coff_bss): Added to handle .bss.
8157 (obj_coff_ident): Added to handle .ident (puts string in .comment

8160 (fixup_mdeps): Change to segment. Call frag_wane after
8162 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8163 adjustment (already happened only for common symbols, but this is
8165 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8166 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8177 (do_scrub_next_char): For \", return " not '.
8178 (symbol_chars): Now const.
8180 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8181 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8183 * config/obj-coff.h: Don't use #elif.
8185 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8186 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8188 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8212 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8213 using ZERO_BASED_SEGMENTS.
8214 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8215 never set segment address for SEG_E2 (.bss) and don't write out
8216 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8217 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8218 definitions, and don't merge tags with non-tags. Check for .bf
8219 rather than just checking whether the second character is b and
8220 the third character is f.
8221 (obj_coff_val): gcc can generate values which we don't handle
8222 correctly; discard information for now, since it only affects the
8223 debugging information.
8224 (tag_find_or_name): Don't insert tags in the symbol table.
8225 (yank_symbols): Don't merge labels.
8226 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8442 * obj-coffbfd.c (write_object_file): check return value of
8445 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8447 * Support for i386-sysv.
8448 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8449 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8450 be used to set them all to zero as was done before.
8451 (fill_section): segment addresses now set in write_object_file.
8452 (fill_section): Don't set STYP_NOLOAD for .bss section.
8453 (fixup_segment): 386 uses strange common symbol format.
8454 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8455 compatibility with SVR3.2 linker.
8456 * configure.in: i386-sysv and i386-sco use coffbfd.

8467 fix i960+non-bfd coff bit rot.
8468 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8469 support for C source listings. (obj_coff_endef): look in the right
8470 part of the symbol for the symbol name
8472 * tc-m68k.c (get_num): make it work for all segments, not just the
8475 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

8486 * tc-z8k.c: lots of bug fixes
8488 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8490 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8491 #elif, since it is not supported by old compilers.
8492 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8493 couple of expressions in tc-m68k.c.
8495 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8497 * read.c (cons): If NO_RELOC is defined, use it.
8499 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8501 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8503 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8504 local labels to start with a .) and set REGISTER_PREFIX to %.
8505 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8523 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8524 sections starting from zero, rather than making them consecutive.
8525 This makes subsequent reloc calculations easier, esp if the object
8526 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8527 allocate lcomm in .data rather than in .bss. It seems that some
8528 tools can't cope with a non-zero sized bss before linkage.
8530 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8532 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8554 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8556 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8557 .word is < -32768 or > 32767. The -J flag causes the error to be
8558 ignored. This is to catch over-sized switches generated by gcc on
8559 systems which don't support the broken .word hack.
8560 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8561 write.c (fixup_segment): check for signed .word overflow if
8562 WARN_SIGNED_OVERFLOW_WORD.

8581 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8583 * input-scrub.c (input_scrub_push): call input_file_begin, not
8585 messages.c (as_perror): print ": " between the passed in error and
8586 the strerror, like perror does.
8588 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8591 From Steve Chamberlain:
8592 Makefile.in: Handle m68*-*-coff*.
8593 read.c, read.h: add mult argument to s_space
8595 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8596 Motorola and MIT syntax; gas can now assemble either type of
8598 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8605 (fixup_segment) set fx_subsy to 0.
8606 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8608 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8611 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8613 * Makefile.in (LIBS): Include opcode library.

8638 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8640 * config/tc-m68k.c (init_table): Now const. Always include 68851
8641 data, so that "bc" is available to 68040 cache instructions.
8642 Added "tt0", "tt1", and 68ec030 variants.
8643 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8644 (enum _register): Added TT0, TT1.
8645 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8646 line number correctly in "internal error" messages. Don't print
8647 architecture-mismatch message for operand errors.
8649 From Colin Smith (colin@wrs.com):
8650 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

8672 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8673 has already been formatted (but may still contain %-characters).
8676 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8678 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8679 written with indirection on the last two operands, which can be
8680 either data or address registers. Added a new operand type 'r'
8681 which accepts either register type. Added '(' to notend stuff in
8682 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8924 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
8926 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8928 * write.c (write_object_file): For b.out format, round up section
8929 start addresses to match required alignment.
8931 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8933 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8934 where gcc looks for it.
8936 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8938 * Makefile.in: Changed some lines to be less confusing for some
8941 * input-file.c: Conditionalize on _IOFBF, not VMS.
8943 * read.c, write.c: Change a series of ifdef/elif to
8944 ifdef/else/ifdef etc.
8946 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
8948 * symbols.c (fb_label_init): fix sizeof to memset.
8950 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
8952 * Makefile.in: install the man page.
8954 * Makefile.in: pass down MAKEINFO explicitly on info.
8956 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
8958 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8960 * flonum-const.c: renamed flonum-konst.c to stop dos name
8963 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8965 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8966 tc-m68k.h to te-sun3.h.
8968 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8970 * configure.in: vxworks68 gets te-sun3.h.
8972 * expr.c: remove limitation that local_labels_dollar or
8973 local_labels_fb must be < 10.
8975 * symbols.c: remove local_labels_dollar, replace with a function
8976 interface for a sparse array. All users adjusted.
8978 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
8980 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8982 * doc/Makefile.in: commented out line for building as-all.texinfo.
8985 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8987 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8989 * Makefile.in: added check target.
8991 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8993 * Makefile.in: added tooldir and program_prefix.
8995 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8997 * write.{c,h} (fix_new): Make these declarations consistent.
8999 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9001 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9004 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9006 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9008 * expr.c (operand): if can't work out what sort of operand it is,
9009 then look through FLT_CHARS for a hint.
9011 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9013 * Makefile.in, configure.in: removed traces of namesubdir,
9014 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9015 copyrights to '92, changed some from Cygnus to FSF.
9017 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9018 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9019 copyrights to '92, changed some from Cygnus to FSF.
9021 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9023 * expr.c: If an expression is single comma, then return with
9024 SEG_ABSENT rather than an error - since the sparc front end does
9025 really strange things with things like fbge,a
9027 * as.h: include bfd.h if using many sections
9028 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9029 local labels didn't work.
9030 * listing.c (list_symbol_table): don't core dump when there's no
9032 * write.c, write.h: call fix_new with the right number of args on
9034 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9037 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9039 * app.c: MRI compatibility - allow single quote to start a string.
9040 * as.c: fix typo recently introduced.
9041 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9042 * expr.c: Much rewriting, to accomodate MRI syntax for
9043 expressions. Also easier to read now.
9044 * listing.c: Put back defuns
9045 * read.c: modified to accept MRI syntax, put back listing pseudo
9046 ops so that an assembler built with NO_LISTING ignores list ops
9048 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9049 machine is a SPARC or a 29K.
9050 * config/obj-aout.c: added s_sect pseudo op
9051 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9052 fill in the timestamp.
9053 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9054 anymore, define all the relocs which the tc-<x> bit will use so we
9055 can translate from them to the coff types.
9056 * config/tc-a29k.c: reloc_type isn't ane enum any more
9057 * config/tc-m68k.c: Added NO_RELOC definition.
9059 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9061 * Makefile.in: put header files before C source for TAGS; remove
9062 references to non-existent syscalls.h.
9064 * read.c, write.c subsegs.c: back out the .bss changes.
9066 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9068 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9072 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9074 * symbols.c (local_label_name): symbols now start with ^A.
9076 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9077 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9078 generate these sections. .align: will use NOP_OPCODE or 0
9079 for padding. This is just for being nice to the
9082 * expr.c (operand): changed to generate local label "\001L0"
9083 starting with a ^A so that it is recognized as a local label.
9085 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9087 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9088 i/o opcodes - inb, inw, outb and outw. string manipulation with
9089 att syntax - scmp, slod, smov, ssca, ssto.
9091 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9092 to just after .file .
9094 In obj_crawl_symbol_chain() where it tries to put the external
9095 symbols apart, with the condition:
9096 (!S_IS_DEFINED(symbolP) &&
9097 !S_IS_DEBUG(symbolP) &&
9098 !SF_GET_STATICS(symbolP))
9099 it was moving too many symbols out. So I switch it back to the
9101 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9103 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9104 so that we don't use the F_RELFLG which make the linker complain
9105 that somebody has stripped the relocation info.
9107 Also, the AIX ld program require that the relocation table
9108 is sorted by r_vaddr like the standard ATT assembler does.
9110 [he also changed the sizeof(struct ...)'s into the coff
9111 style FOOSZ macros. I'm not sure this is right, but I can't
9112 remember why. xoxorich.]
9114 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9116 * Makefile.in, configure.in, doc: use the doc. Build it, install
9119 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9121 * read.c: white space and comments only.
9123 * configure.in: use the new atof-ns32.c for ns32k.
9125 * write.c: comment change only.
9127 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9128 aren't yet integrated.
9130 * tc-i860.[hc]: blew off the dust. Something must still be done
9131 about conflicting relocation types.
9133 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9136 * tc-i960.c, tc-sparc.c: white space and comments only.
9138 * tc-a29k.h: delete duplicate macro definition.
9140 * new file atof-ns32k.c copied from hack's last unreleased gas.
9142 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9144 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9147 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9148 ChangeLog's prior to this are sketchy at best. I have logs.
9149 They just aren't ChangeLogs.
9156 version-control: never
