3 * read.c (emit_expr): Use memset to zero out memory, rather than
4 going through md_number_to_chars. This permits handling symbolic
5 arguments when the size is larger than sizeof (valueT), if
6 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
8 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

128 new VMS symbol-type macros; signed and unsigned quadword integers,
129 for `long long' support. Their values come from the existing
130 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
131 VMS debugger now recognizes `long long' variables correctly.
132 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
133 for gcc2's predefined types "long double" (same as double, as
134 per gcc's current state), "long long int", "long long unsigned
135 int", and final `otherwise' case (to avoid uninitialized type
136 and size fields). [caveat: predefined types "complex int",
137 "complex float", "complex double", and "complex long double" are
140 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead

151 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
152 the contents of the GAS_VERSION string when falling back to it for
153 language processor identification.
155 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of

526 argument, the reloc type.
527 (load_register): Pass reloc type to macro_build for 'u'.
528 (macro): Likewise. For M_LA_AB permit a difference expression
529 when generating embedded PIC code between an arbitrary symbol and
530 a symbol in the .text section.

532 BFD_RELOC_PCREL_LO16 to be emitted.
533 (md_apply_fix): Check that most relocs are not PC relative.
534 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
535 (tc_gen_reloc): Change #error to as_fatal. Handle
536 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.

575 elf_tc_make_sections stuff. It was there to support PA braindamage
576 which has been fixed, and in the case of elf_tc_make_sections is
577 redundant with elf_tc_final_processing.
579 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

597 don't spew remainder of input file in error message.
598 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
599 message with reloc type and try to process remainder of file.
601 * doc/Makefile.in (install-info-as, install-info-gasp): New
602 targets, now explicitly checking $(srcdir) for info files.
603 (install-info): Depend on both of them; do nothing more.

611 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
612 flag rather than signedp field. Only permit extended range if
613 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
614 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
616 * config/tc-ppc.c (ppc_size): New static variable.
617 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
618 (md_begin): If an instruction has a size specific flag set, only
619 add it if we are assembling that size.
621 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
623 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
624 cross section PC relative relocs right for COFF and ELF.
626 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
628 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

634 the type of symbol set symbols which happen to be in the absolute
635 or undefined section.
637 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
639 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
640 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
641 and -many (all architectures).

651 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
652 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
654 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
655 branch with an instruction that uses $at, in case the branch is
657 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
658 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
659 to make it pcrel_offset.
660 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
661 reloc->address; another gruesome hack to get gas reloc handling to
664 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
666 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

670 (md_assemble): Call it.
671 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
673 (lituse_pending): New variable. Set by anything that generates a
674 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
675 tested by code that might want to emit a LITUSE reloc.
676 (emit_unaligned_io): New function. Currently calls md_assemble,
677 but it should eventually be converted to generate the insn itself
678 and call emit_insn directly.
679 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
680 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
681 emit_bis_r): Likewise.

688 the value can't be resolved.
690 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
692 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
693 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
694 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
696 (mips_force_relocation): New function.
697 (md_apply_fix): Set fixP->fx_done appropriately.

706 * config/tc-mips.c (enum mips_pic_level): New enum.
707 (mips_pic): Change from int to enum mips_pic_level. Change all
708 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
709 (load_address): Handle EMBEDDED_PIC.
710 (macro): Handle EMBEDDED_PIC in all PIC cases.
711 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
712 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
713 -non_shared to use NO_PIC (this is how the Irix 5 assembler
714 works). Do not permit -G with SVR4_PIC.
715 (s_abicalls): Warn if -G was used, and force -G 0.
716 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
717 anything but a.out, not just for ELF. For ECOFF, don't generate a
718 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
720 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
722 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

728 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
730 * Makefile.in (config-stamp): If `defs' is defined, emit a
731 preprocessor directive to create a macro named by this value into
732 config.new; don't explicitly go for BFD_ASSEMBLER.
733 * configure.in: Define `defs', not `BFDDEF'. Set it to
734 MANY_SEGMENTS for any obj-coffbfd target.
735 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
736 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
738 (LOCAL_LOADLIBES): Deleted.
739 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
740 * config/m88kcoff.mt (TDEFINES): Ditto.

766 bfd_set_symtab is called.
767 (dump_section_relocs): Note whether a symbol is a section symbol
769 (adjust_reloc_syms): For now, always supply an absolute symbol for
770 fixups without symbols but not yet `done'. Use section_symbol to
771 get the symbol, instead of going directly for abs_symbol.
772 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
773 reloc is not a section symbol and is not in the symbol table.
774 (set_symtab): New function, broken out from write_object_file.
775 Counts symbol table instead of relying on an earlier count.
776 (write_object_file): Call set_symtab, but do it after potentially
777 invoking the *_frob_file macros. Don't bother counting symbols.
778 Call symbol_remove, instead of expanding it in place. Moved the
779 conditionalized `object_file_size' declaration down to
780 conditionalized block where it's used. When using the absolute
781 symbol for a fixup without a symbol, set sy_used_in_reloc.
782 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
783 the correct symbol for the absolute section.
785 * subsegs.c (section_symbol): Use symbol_new instead of
786 symbol_make, since we may want it to go into the symbol table.
787 Make the new symbol have internal linkage. If
788 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
789 symbol with the newly created GAS symbol.
790 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
791 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

796 (in_signed_range): New function.
798 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
799 (sparc_ip, label "immediate"): Reject constants for pcrel
800 instructions only if the relocation type indicates a "call"
801 instruction and the offset is within range of a "jmpl %g0". If
802 it's not in range, use the absolute section symbol plus an offset.
803 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
805 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
807 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
810 * configure.in: Eliminated all targets using obj-coff but not
811 defining BFD_ASSEMBLER; I think all such targets that are
812 supported will be matched by real CPU-OS combinations earlier in
814 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
815 some comments about the dpx2 configuration, but left it disabled,
816 since it couldn't be reached before.
817 (target a29k-amd-ebmonold): Deleted.
819 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
821 * config/tc-hppa.c (pa_import): Correctly handle importing of an
822 already defined symbol.

827 the 'j' operand if there are no further alternatives for this
830 * config/obj-coffbfd.c (adjust_stab_section): Initialize
831 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
832 is not SEG_UNKNOWN rather than checking whether it is >= 0.
834 * config/tc-mips.c (mips_align): Take new argument, label, and use
835 it instead of global insn_label.
836 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
837 call to mips_emit_delay and pass it to mips_align.
839 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
841 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
843 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
844 argument to a .callinfo directive. Don't loop forever on errors.
846 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
847 use pre-defined registers as arguments.
849 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
851 * write.c (write_object_file): Check both S_IS_LOCAL and
852 S_IS_EXTERNAL when deciding whether to discard a symbol.
854 * config-gas.com: Scan Makefile.in, not version.c, for current
855 version number. Delete all versions of temp files when finished
856 with them. Create config.h.
858 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
859 values to reduce number of lookups with S_GET_VALUE. Skip debug

861 holger@botbso.rhein-main.de.)
862 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
863 field. (Also from Holger Teutsch.) Watch for a would-be register
864 mask that spans frags.
866 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
867 this_base, not line_base. (Patch from Andreas Arens,
868 ari@obelix.av.rwth-aachen.de.)
870 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
871 look local if they're exported or undefined. Used to be done for
874 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
875 Get it from the looked-up symbol, instead of using the string from
876 the input stream, which is no longer null-terminated.
877 (LEX_PCT): New macro, defaults to 0.
878 (lex_type): Use it for `%'.
880 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
881 (vip_op): Now static, and returns void. Callers changed. Added
883 (vip): Ditto. Call as_fatal directly if a program bug is

941 (obj_coff_section): Declare.
942 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
943 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
944 work. It still doesn't. It now fails to compile, instead of
945 silently compiling to do nothing.
946 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
948 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2661 pass new argument for i, j and o cases.
2662 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2883 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2884 the table, require that the one without bit 0x1000000 set come
2885 first. Require further that it be case 'b' or 'P'. The a29k
2886 opcode table already meets these constraints.
2887 (machine_ip): When handling case 'i' or 'A', make sure that the

2939 * write.c (write_relocs): For relocs that are pc_relative and
2940 pcrel_offset and not partial_inplace, adjust reloc->addend to

2996 for keeping or rejecting configurations still under development;
2997 default is to assume production environment, and reject configs
2998 still being worked on. Mark Elf configurations (except sparc and
2999 i386) as developmental. Deleted cases matching some generic names
3000 in favor of more specific names. (E.g., when we get Alpha

3017 through inclusion of tc-hppa.h. Delete all forward declarations
3018 for functions only used within tc-hppa.c, likewise for structures,
3019 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3020 conditional code in a few small places.
3022 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3023 structures, global variables, forward declarations together.

3025 conditional code -- try to group conditional code together
3026 into a few places. Make all functions and variables which
3027 are only used within tc-hppa.c static. PARAMize all functions.
3028 Add comments to functions. Delete unused functions, variables,
3029 #defines, etc. Delete unused members within structures. Delete
3030 ldil;ble hacks -- it is believed they were installed to work
3031 around old gas bugs. Avoid using mixed case for local
3032 functions, variables, and structures. Fix formatting problems
3033 not found by GNU-indent. Add FIXME notices for things which
3034 should be worked on the near future. Delete lots of old
3035 useless (1.36 PA-SOM) code.

3054 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
3055 of elf32_symbol_type.
3056 (pa_export_args): Likewise.

3064 a multiple of the section alignment rather than always a
3067 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3108 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3110 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3111 ELF, since the ELF object format does not have these type of
3112 relocations. Change the abort into as as_bad and return
3113 BFD_RELOC_NONE to silence compiler warnings.
3114 (md_assemble): Keep track of the instruction size. Allow white
3115 space between the $ and the constant for compatibility with older
3116 gases and other assemblers.
3117 (i386_operand): Skip spaces between $ and expression.
3118 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5553 * config/tc-mips.c (macro): Use $AT if target register is zero in
5554 load instruction, which it can be for a floating point load.

5628 prototypes for all static functions. Moved existing minimal
5629 debugging format support info #ifndef OBJ_ECOFF blocks.

5678 * make-gas.com: Find obstack.obj if it's not in the current
5680 * read.c (s_ignore): Don't declare is_end_of_line. It's
5681 redundant, and triggers a VMS gcc compiler bug.
5683 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5684 current segment as an argument. (Ignored in all cases but VMS.)

6002 (operand): Treat zero byte as end-of-operand.
6004 * configure.in (per-target): Look for with_bfd_assembler option.
6005 For now, only accept "no", until the merge is done.
6007 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6008 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6014 * expr.c: Add "const" modifier to hex_value.
6015 * symbols.c: Finish conversion to S_* macros in the VMS only
6016 parts of the program. Add "const" modifier to
6017 md_[long,short]_jump_size. Remove declaration of const_flag
6018 (which will be declared in obj-vms.h).
6019 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6020 Fix arguments to VMS_write_object_file.
6021 * config-gas.com: New file. Script for VMS systems to set up the
6022 configuration to build gas for VMS, and create config.status.

6030 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6031 types of malformed stabs. Change parsing algorithm so that we are

6038 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6039 as symbols as well in the object file. Look for external functions

6081 mapping to segT enum values.
6082 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6083 if these are used or defined, if BFD_ASSEMBLER.
6084 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6085 subseg_new split into two functions.
6086 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6088 * as.h (volatile): Don't define if already defined.
6089 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6099 * These are based on patches from Minh Tran-le
6100 <mtranle@paris.intellicorp.com>.
6101 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6102 obj_format coffbfd and gas_target i386coff for target.
6103 (i[34]86-*-isc*): New host (uses sysv).
6104 * config/i386aix.mt: Removed (no longer used).
6105 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6107 (LDFLAGS): Added, defined as -shlib.
6108 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6109 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6110 (DOT_LABEL_PREFIX): Define.
6111 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6112 name rather than L0\001.
6113 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6115 * symbols.c, symbols.h (local_bss_counter): Removed.
6116 * write.c (write_object_file): bss no longer uses
6117 local_bss_counter. Pass correct data and bss size to
6118 VMS_write_object_file.
6119 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
6120 argument, rather than using local_bss_counter.
6121 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
6122 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
6123 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
6124 (size_section): Restored sanity check.
6125 (do_relocs_for): Base section address on s_paddr rather than
6126 computing it. Adjust a29k R_IHIHALF special case to account for
6127 section paddr (used to require paddr to be zero). If there are no
6128 reclos, set s_relptr to 0. Set relocation size in object_headers.
6129 (fill_section): Always set s_vaddr here, removing
6130 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6131 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6132 Set STYP_INFO for .comment.
6133 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6134 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
6135 (crawl_symbols): Handle 8 character section name correctly. Use
6136 H_{SET,GET}_* macros.
6137 (do_linenos_for): Set lineno size in object_headers.
6138 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6139 set s_vaddr here. If string_byte_count remains 4, set it back to
6140 0, and only write strings out if there are some. Call
6141 fill_section before do_relocs_for and do_linenos_for.
6142 (obj_coff_section): Handle optional quoted second argument giving
6143 section characteristics.
6144 (obj_coff_bss): Added to handle .bss.
6145 (obj_coff_ident): Added to handle .ident (puts string in .comment
6147 (obj_coff_lcomm): Put common symbols in .bss, not .data.
6148 (fixup_mdeps): Change to segment. Call frag_wane after
6150 (fixup_segment): Explicitly check S_IS_COMMON before making 386
6151 adjustment (already happened only for common symbols, but this is
6153 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
6154 * config/tc-i386.c (s_bss): Don't use if I386COFF.

6159 (LOCAL_LABEL): Removed definition.
6160 (DOT_LABEL_PREFIX): Defined.
6162 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
6164 * app.c (app_push): Use memcpy, not bcopy.
6165 (do_scrub_next_char): For \", return " not '.
6166 (symbol_chars): Now const.
6168 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6169 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6171 * config/obj-coff.h: Don't use #elif.
6173 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6174 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6176 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6198 SEG_BSS, fill with NOP_OPCODE.
6199 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6200 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6201 using ZERO_BASED_SEGMENTS.
6202 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6203 never set segment address for SEG_E2 (.bss) and don't write out
6204 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6205 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6206 definitions, and don't merge tags with non-tags. Check for .bf
6207 rather than just checking whether the second character is b and
6208 the third character is f.
6209 (obj_coff_val): gcc can generate values which we don't handle
6210 correctly; discard information for now, since it only affects the
6211 debugging information.
6212 (tag_find_or_name): Don't insert tags in the symbol table.
6213 (yank_symbols): Don't merge labels.
6214 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6217 (obj_coff_section): Accept and ignore a trailing quoted string, as
6218 used in AT&T i386 syntax.
6219 (fixup_segment): Take segment as argument. On the i386, adjust PC
6220 relative addends by the segment vaddr.
6221 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6222 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

6234 power-of-two alignment for .align.
6236 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6237 and leave everything else alone.

6269 options. Updated options documentation for m68k. Some minor
6270 wording/punctuation changes.

6360 could be doing emulation.
6362 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6365 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6368 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

6394 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6396 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6397 constant will not fit in an immediate field.
6398 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6400 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

6433 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6435 * Support for i386-sysv.
6436 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6460 * tc-m68k.c (get_num): make it work for all segments, not just the
6463 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6465 * configure.in: recognize i386-*-bsd emulation.

6474 * tc-z8k.c: lots of bug fixes
6476 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6478 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6479 #elif, since it is not supported by old compilers.
6480 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6481 couple of expressions in tc-m68k.c.
6483 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6485 * read.c (cons): If NO_RELOC is defined, use it.
6487 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6489 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6491 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6492 local labels to start with a .) and set REGISTER_PREFIX to %.
6493 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6495 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6497 * messages.c: Comment changes.
6499 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6502 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6504 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6506 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6509 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6511 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6512 sections starting from zero, rather than making them consecutive.
6513 This makes subsequent reloc calculations easier, esp if the object
6514 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6515 allocate lcomm in .data rather than in .bss. It seems that some
6516 tools can't cope with a non-zero sized bss before linkage.
6518 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6520 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6521 throughout. That enum no longer means what we thought it meant.
6523 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6524 "-mno-688[58]1" options.
6526 * tc-m68k.c: Added CPU32 support.
6528 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6530 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

6534 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6535 Change LIBDEPS dependence to LIBS.
6537 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6539 * Makefile.in (install): if $(tooldir) exists, install as in
6542 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6544 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6545 .word is < -32768 or > 32767. The -J flag causes the error to be
6546 ignored. This is to catch over-sized switches generated by gcc on
6547 systems which don't support the broken .word hack.
6548 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6549 write.c (fixup_segment): check for signed .word overflow if
6550 WARN_SIGNED_OVERFLOW_WORD.
6552 * write.c (fixup_segment): fixed missing parens in expression
6553 checking for byte or word overflow.
6555 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6556 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6557 WARN_SIGNED_OVERFLOW_WORD.

6565 * obj-coffbfd.h : added stuff
6566 * tc-i386.c (tc_coff_fix2rtype): new function
6567 * tc-i386.h : new coff defines
6569 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6571 * input-scrub.c (input_scrub_push): call input_file_begin, not
6573 messages.c (as_perror): print ": " between the passed in error and
6574 the strerror, like perror does.
6576 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6578 * Makefile.in: use gas_target instead of modifying target_cpu.
6579 From Steve Chamberlain:

6666 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6667 written with indirection on the last two operands, which can be
6668 either data or address registers. Added a new operand type 'r'
6669 which accepts either register type. Added '(' to notend stuff in
6670 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

7009 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7011 * expr.c: If an expression is single comma, then return with
7012 SEG_ABSENT rather than an error - since the sparc front end does
7013 really strange things with things like fbge,a
7015 * as.h: include bfd.h if using many sections
7016 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

7025 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7027 * app.c: MRI compatibility - allow single quote to start a string.

7030 * expr.c: Much rewriting, to accomodate MRI syntax for
7031 expressions. Also easier to read now.
7032 * listing.c: Put back defuns
7033 * read.c: modified to accept MRI syntax, put back listing pseudo
7034 ops so that an assembler built with NO_LISTING ignores list ops
7036 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7037 machine is a SPARC or a 29K.
7038 * config/obj-aout.c: added s_sect pseudo op
7039 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7040 fill in the timestamp.
7041 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7042 anymore, define all the relocs which the tc-<x> bit will use so we
7043 can translate from them to the coff types.
7044 * config/tc-a29k.c: reloc_type isn't ane enum any more
7045 * config/tc-m68k.c: Added NO_RELOC definition.

7064 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7065 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7066 generate these sections. .align: will use NOP_OPCODE or 0
7067 for padding. This is just for being nice to the
7070 * expr.c (operand): changed to generate local label "\001L0"
7071 starting with a ^A so that it is recognized as a local label.
7073 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7075 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7076 i/o opcodes - inb, inw, outb and outw. string manipulation with
7077 att syntax - scmp, slod, smov, ssca, ssto.
7079 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7080 to just after .file .
7082 In obj_crawl_symbol_chain() where it tries to put the external
7083 symbols apart, with the condition:
7084 (!S_IS_DEFINED(symbolP) &&
7085 !S_IS_DEBUG(symbolP) &&
7086 !SF_GET_STATICS(symbolP))
7087 it was moving too many symbols out. So I switch it back to the
7089 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7091 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7092 so that we don't use the F_RELFLG which make the linker complain
7093 that somebody has stripped the relocation info.
7095 Also, the AIX ld program require that the relocation table
7096 is sorted by r_vaddr like the standard ATT assembler does.
7098 [he also changed the sizeof(struct ...)'s into the coff
7099 style FOOSZ macros. I'm not sure this is right, but I can't
7100 remember why. xoxorich.]

7104 * Makefile.in, configure.in, doc: use the doc. Build it, install
7107 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
7109 * read.c: white space and comments only.
7111 * configure.in: use the new atof-ns32.c for ns32k.
7113 * write.c: comment change only.
7115 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7116 aren't yet integrated.
7118 * tc-i860.[hc]: blew off the dust. Something must still be done
7119 about conflicting relocation types.
7121 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7124 * tc-i960.c, tc-sparc.c: white space and comments only.
7126 * tc-a29k.h: delete duplicate macro definition.
7128 * new file atof-ns32k.c copied from hack's last unreleased gas.

7132 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7135 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7136 ChangeLog's prior to this are sketchy at best. I have logs.
7137 They just aren't ChangeLogs.
