83 VMS debugger now recognizes `long long' variables correctly.
84 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
85 for gcc2's predefined types "long double" (same as double, as
86 per gcc's current state), "long long int", "long long unsigned
87 int", and final `otherwise' case (to avoid uninitialized type

89 "complex float", "complex double", and "complex long double" are
92 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead

105 language processor identification.
107 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of

452 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
454 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

458 directory, and specify PSECT attributes explicitly to linker.
459 Also added missing label.
460 * Makefile.in (stamp-mk.com): Reference new variable

527 elf_tc_make_sections stuff. It was there to support PA braindamage
528 which has been fixed, and in the case of elf_tc_make_sections is

549 don't spew remainder of input file in error message.
550 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
551 message with reloc type and try to process remainder of file.
553 * doc/Makefile.in (install-info-as, install-info-gasp): New
554 targets, now explicitly checking $(srcdir) for info files.

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

591 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
592 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

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

622 (md_assemble): Call it.
623 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
625 (lituse_pending): New variable. Set by anything that generates a
626 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
627 tested by code that might want to emit a LITUSE reloc.
628 (emit_unaligned_io): New function. Currently calls md_assemble,
629 but it should eventually be converted to generate the insn itself
630 and call emit_insn directly.
631 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
632 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
633 emit_bis_r): Likewise.

640 the value can't be resolved.
642 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
644 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
645 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

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

680 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
682 * Makefile.in (config-stamp): If `defs' is defined, emit a
683 preprocessor directive to create a macro named by this value into
684 config.new; don't explicitly go for BFD_ASSEMBLER.
685 * configure.in: Define `defs', not `BFDDEF'. Set it to
686 MANY_SEGMENTS for any obj-coffbfd target.
687 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
688 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
690 (LOCAL_LOADLIBES): Deleted.
691 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
692 * config/m88kcoff.mt (TDEFINES): Ditto.

718 bfd_set_symtab is called.
719 (dump_section_relocs): Note whether a symbol is a section symbol
721 (adjust_reloc_syms): For now, always supply an absolute symbol for
722 fixups without symbols but not yet `done'. Use section_symbol to
723 get the symbol, instead of going directly for abs_symbol.
724 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
725 reloc is not a section symbol and is not in the symbol table.
726 (set_symtab): New function, broken out from write_object_file.
727 Counts symbol table instead of relying on an earlier count.
728 (write_object_file): Call set_symtab, but do it after potentially
729 invoking the *_frob_file macros. Don't bother counting symbols.
730 Call symbol_remove, instead of expanding it in place. Moved the
731 conditionalized `object_file_size' declaration down to
732 conditionalized block where it's used. When using the absolute
733 symbol for a fixup without a symbol, set sy_used_in_reloc.
734 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
735 the correct symbol for the absolute section.
737 * subsegs.c (section_symbol): Use symbol_new instead of
738 symbol_make, since we may want it to go into the symbol table.
739 Make the new symbol have internal linkage. If
740 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
741 symbol with the newly created GAS symbol.
742 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
743 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

748 (in_signed_range): New function.
750 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
751 (sparc_ip, label "immediate"): Reject constants for pcrel
752 instructions only if the relocation type indicates a "call"
753 instruction and the offset is within range of a "jmpl %g0". If
754 it's not in range, use the absolute section symbol plus an offset.
755 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
757 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
759 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
762 * configure.in: Eliminated all targets using obj-coff but not
763 defining BFD_ASSEMBLER; I think all such targets that are
764 supported will be matched by real CPU-OS combinations earlier in
766 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
767 some comments about the dpx2 configuration, but left it disabled,
768 since it couldn't be reached before.
769 (target a29k-amd-ebmonold): Deleted.
771 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

779 the 'j' operand if there are no further alternatives for this
782 * config/obj-coffbfd.c (adjust_stab_section): Initialize
783 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
784 is not SEG_UNKNOWN rather than checking whether it is >= 0.
786 * config/tc-mips.c (mips_align): Take new argument, label, and use
787 it instead of global insn_label.
788 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
789 call to mips_emit_delay and pass it to mips_align.
791 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
793 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
795 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
796 argument to a .callinfo directive. Don't loop forever on errors.
798 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
799 use pre-defined registers as arguments.
801 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
803 * write.c (write_object_file): Check both S_IS_LOCAL and
804 S_IS_EXTERNAL when deciding whether to discard a symbol.
806 * config-gas.com: Scan Makefile.in, not version.c, for current
807 version number. Delete all versions of temp files when finished
808 with them. Create config.h.
810 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
811 values to reduce number of lookups with S_GET_VALUE. Skip debug
812 symbols to avoid "a really nasty bug". (From Holger Teutsch,
813 holger@botbso.rhein-main.de.)
814 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
815 field. (Also from Holger Teutsch.) Watch for a would-be register
816 mask that spans frags.
818 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
819 this_base, not line_base. (Patch from Andreas Arens,
820 ari@obelix.av.rwth-aachen.de.)
822 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
823 look local if they're exported or undefined. Used to be done for
826 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
827 Get it from the looked-up symbol, instead of using the string from
828 the input stream, which is no longer null-terminated.
829 (LEX_PCT): New macro, defaults to 0.
830 (lex_type): Use it for `%'.
832 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
833 (vip_op): Now static, and returns void. Callers changed. Added
835 (vip): Ditto. Call as_fatal directly if a program bug is

839 * Makefile.in (literal.o): Provide dependencies.
841 * configure.in: Set new makefile variable OPCODES_LIB.

894 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
895 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2949 default is to assume production environment, and reject configs
2950 still being worked on. Mark Elf configurations (except sparc and
2951 i386) as developmental. Deleted cases matching some generic names
2952 in favor of more specific names. (E.g., when we get Alpha

2971 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2972 conditional code in a few small places.

2978 into a few places. Make all functions and variables which
2979 are only used within tc-hppa.c static. PARAMize all functions.
2980 Add comments to functions. Delete unused functions, variables,
2981 #defines, etc. Delete unused members within structures. Delete
2982 ldil;ble hacks -- it is believed they were installed to work
2983 around old gas bugs. Avoid using mixed case for local
2984 functions, variables, and structures. Fix formatting problems
2985 not found by GNU-indent. Add FIXME notices for things which
2986 should be worked on the near future. Delete lots of old

3007 of elf32_symbol_type.
3008 (pa_export_args): Likewise.
3009 (elf_hppa_final_processing): Likewise.

3016 a multiple of the section alignment rather than always a
3019 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3060 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3062 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3063 ELF, since the ELF object format does not have these type of
3064 relocations. Change the abort into as as_bad and return
3065 BFD_RELOC_NONE to silence compiler warnings.
3066 (md_assemble): Keep track of the instruction size. Allow white
3067 space between the $ and the constant for compatibility with older
3068 gases and other assemblers.
3069 (i386_operand): Skip spaces between $ and expression.

5429 source directory, if that's not the current directory.
5431 * configure.in (per-host): Accept MIPS host with BSD version

5457 avoid some redefinition complaints on some systems.
5458 (const, volatile): Don't need these conditionally defined if we
5459 use CONST and VOLATILE from ansidecl.h.
5460 (seg_name): Use CONST, not const.
5462 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5464 * config/tc-mips.c: Reindented to GNU standards.

5468 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5469 (fixup_segment): Add a29k special case; the linker is not prepared
5470 to see a segment offset here.
5472 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5475 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5477 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5478 srcdir, might be in objdir.

5497 * Makefile.in (targ-cpu.o): Depend on config.h.
5499 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5501 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5502 dropping a space immediately following an identifier.

5504 lines; I don't think that can be done portably.
5505 * config/tc-mips.c (macro): Use $AT if target register is zero in
5506 load instruction, which it can be for a floating point load.
5508 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5529 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5531 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5532 to be on a single line.

5580 prototypes for all static functions. Moved existing minimal
5581 debugging format support info #ifndef OBJ_ECOFF blocks.

5630 * make-gas.com: Find obstack.obj if it's not in the current
5632 * read.c (s_ignore): Don't declare is_end_of_line. It's
5633 redundant, and triggers a VMS gcc compiler bug.

5950 * expr.c (operand): If character other than comma or newline is a
5951 logical end-of-line character, use the newline case.
5952 From Eric Youngdale:
5953 (operand): Set X_add_number field for floating-point numbers.
5954 (operand): Treat zero byte as end-of-operand.
5956 * configure.in (per-target): Look for with_bfd_assembler option.
5957 For now, only accept "no", until the merge is done.
5959 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5960 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5966 * expr.c: Add "const" modifier to hex_value.
5967 * symbols.c: Finish conversion to S_* macros in the VMS only
5968 parts of the program. Add "const" modifier to
5969 md_[long,short]_jump_size. Remove declaration of const_flag
5970 (which will be declared in obj-vms.h).
5971 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5972 Fix arguments to VMS_write_object_file.
5973 * config-gas.com: New file. Script for VMS systems to set up the
5974 configuration to build gas for VMS, and create config.status.
5975 * make-gas.com: Redone to work with new scheme.
5976 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5978 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5979 will swap bytes if needed on a big endian system. Use throughout
5981 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5982 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5983 types of malformed stabs. Change parsing algorithm so that we are
5984 more certain of having all of the information that we need on hand.
5985 * obj-vms.c (final_forward_reference): New function, used to help
5986 resolve the data types of as many struct elements as possible

5990 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5991 as symbols as well in the object file. Look for external functions

6004 SEG_DATA or SEG_E1 if needed.
6005 (s_lcomm): Likewise with bss_section.
6006 (s_fill): Use memset, not bzero.
6008 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
6010 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

6031 absent_section, text_section, data_section, bss_section): If
6032 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6033 mapping to segT enum values.
6034 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6035 if these are used or defined, if BFD_ASSEMBLER.
6036 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6037 subseg_new split into two functions.
6038 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6040 * as.h (volatile): Don't define if already defined.
6041 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6043 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6044 declare with format attribute for -Wformat checking.
6046 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6048 * app.c, config/tc-*.c: Don't include read.h, since it is already
6051 * These are based on patches from Minh Tran-le
6052 <mtranle@paris.intellicorp.com>.
6053 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6054 obj_format coffbfd and gas_target i386coff for target.

6056 * config/i386aix.mt: Removed (no longer used).
6057 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6059 (LDFLAGS): Added, defined as -shlib.
6060 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6061 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6062 (DOT_LABEL_PREFIX): Define.
6063 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6064 name rather than L0\001.
6065 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6067 * symbols.c, symbols.h (local_bss_counter): Removed.
6068 * write.c (write_object_file): bss no longer uses
6069 local_bss_counter. Pass correct data and bss size to
6070 VMS_write_object_file.
6071 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
6072 argument, rather than using local_bss_counter.

6076 (size_section): Restored sanity check.
6077 (do_relocs_for): Base section address on s_paddr rather than
6078 computing it. Adjust a29k R_IHIHALF special case to account for
6079 section paddr (used to require paddr to be zero). If there are no
6080 reclos, set s_relptr to 0. Set relocation size in object_headers.
6081 (fill_section): Always set s_vaddr here, removing
6082 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6083 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6084 Set STYP_INFO for .comment.
6085 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6086 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6088 H_{SET,GET}_* macros.
6089 (do_linenos_for): Set lineno size in object_headers.
6090 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6091 set s_vaddr here. If string_byte_count remains 4, set it back to
6092 0, and only write strings out if there are some. Call
6093 fill_section before do_relocs_for and do_linenos_for.
6094 (obj_coff_section): Handle optional quoted second argument giving
6095 section characteristics.

6123 * config/obj-coff.h: Don't use #elif.
6125 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

6165 (yank_symbols): Don't merge labels.
6166 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6312 could be doing emulation.
6314 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6317 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6387 * Support for i386-sysv.
6388 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6428 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6430 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6431 #elif, since it is not supported by old compilers.
6432 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6433 couple of expressions in tc-m68k.c.
6435 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

6461 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6463 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6464 sections starting from zero, rather than making them consecutive.
6465 This makes subsequent reloc calculations easier, esp if the object
6466 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6467 allocate lcomm in .data rather than in .bss. It seems that some
6468 tools can't cope with a non-zero sized bss before linkage.

6491 * Makefile.in (install): if $(tooldir) exists, install as in
6494 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6496 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6497 .word is < -32768 or > 32767. The -J flag causes the error to be
6498 ignored. This is to catch over-sized switches generated by gcc on
6499 systems which don't support the broken .word hack.
6500 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6501 write.c (fixup_segment): check for signed .word overflow if
6502 WARN_SIGNED_OVERFLOW_WORD.

6521 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6523 * input-scrub.c (input_scrub_push): call input_file_begin, not
6525 messages.c (as_perror): print ": " between the passed in error and
6526 the strerror, like perror does.
6528 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6530 * Makefile.in: use gas_target instead of modifying target_cpu.
6531 From Steve Chamberlain:
6532 Makefile.in: Handle m68*-*-coff*.

6544 (write_object_file) call fixup_mdeps
6545 (fixup_segment) set fx_subsy to 0.
6546 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6548 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6551 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6553 * Makefile.in (LIBS): Include opcode library.
6555 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6576 little endian byte order (used to use endianness of host).
6578 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6580 * config/tc-m68k.c (init_table): Now const. Always include 68851
6581 data, so that "bc" is available to 68040 cache instructions.
6582 Added "tt0", "tt1", and 68ec030 variants.
6583 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6584 (enum _register): Added TT0, TT1.

6616 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6618 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6619 written with indirection on the last two operands, which can be
6620 either data or address registers. Added a new operand type 'r'
6621 which accepts either register type. Added '(' to notend stuff in
6622 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6734 characteristics have been), default to 68020. Don't need extra
6735 quotes around error string.

6817 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6819 * write.c (write_object_file): keep the fix_tail clean, which
6820 fixes a bug in -R where relocations were being lost.
6822 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6824 * configure.in: recognize m680x0 as having sun3 emulation mode for

6868 * write.c (write_object_file): For b.out format, round up section
6869 start addresses to match required alignment.
6871 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6873 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6874 where gcc looks for it.
6876 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6878 * Makefile.in: Changed some lines to be less confusing for some

6948 * expr.c (operand): if can't work out what sort of operand it is,
6949 then look through FLT_CHARS for a hint.
6951 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6953 * Makefile.in, configure.in: removed traces of namesubdir,

6957 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6958 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6959 copyrights to '92, changed some from Cygnus to FSF.
6961 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6963 * expr.c: If an expression is single comma, then return with
6964 SEG_ABSENT rather than an error - since the sparc front end does
6965 really strange things with things like fbge,a
6967 * as.h: include bfd.h if using many sections
6968 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6969 local labels didn't work.
6970 * listing.c (list_symbol_table): don't core dump when there's no
6972 * write.c, write.h: call fix_new with the right number of args on
6974 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6977 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6979 * app.c: MRI compatibility - allow single quote to start a string.
6980 * as.c: fix typo recently introduced.
6981 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6982 * expr.c: Much rewriting, to accomodate MRI syntax for
6983 expressions. Also easier to read now.
6984 * listing.c: Put back defuns
6985 * read.c: modified to accept MRI syntax, put back listing pseudo
6986 ops so that an assembler built with NO_LISTING ignores list ops
6988 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6989 machine is a SPARC or a 29K.
6990 * config/obj-aout.c: added s_sect pseudo op
6991 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6992 fill in the timestamp.
6993 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6994 anymore, define all the relocs which the tc-<x> bit will use so we
6995 can translate from them to the coff types.
6996 * config/tc-a29k.c: reloc_type isn't ane enum any more
6997 * config/tc-m68k.c: Added NO_RELOC definition.
6999 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7001 * Makefile.in: put header files before C source for TAGS; remove
7002 references to non-existent syscalls.h.
7004 * read.c, write.c subsegs.c: back out the .bss changes.
7006 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7008 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7012 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7014 * symbols.c (local_label_name): symbols now start with ^A.
7016 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7017 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7018 generate these sections. .align: will use NOP_OPCODE or 0
7019 for padding. This is just for being nice to the
7022 * expr.c (operand): changed to generate local label "\001L0"
7023 starting with a ^A so that it is recognized as a local label.
7025 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7027 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7028 i/o opcodes - inb, inw, outb and outw. string manipulation with
7029 att syntax - scmp, slod, smov, ssca, ssto.
7031 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7032 to just after .file .
7034 In obj_crawl_symbol_chain() where it tries to put the external
7035 symbols apart, with the condition:
7036 (!S_IS_DEFINED(symbolP) &&
7037 !S_IS_DEBUG(symbolP) &&
7038 !SF_GET_STATICS(symbolP))
7039 it was moving too many symbols out. So I switch it back to the
7041 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7043 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7044 so that we don't use the F_RELFLG which make the linker complain
7045 that somebody has stripped the relocation info.
7047 Also, the AIX ld program require that the relocation table
7048 is sorted by r_vaddr like the standard ATT assembler does.
7050 [he also changed the sizeof(struct ...)'s into the coff
7051 style FOOSZ macros. I'm not sure this is right, but I can't
7052 remember why. xoxorich.]
7054 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7063 * configure.in: use the new atof-ns32.c for ns32k.
7065 * write.c: comment change only.
7067 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7068 aren't yet integrated.
7070 * tc-i860.[hc]: blew off the dust. Something must still be done
7071 about conflicting relocation types.
7073 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7076 * tc-i960.c, tc-sparc.c: white space and comments only.
7078 * tc-a29k.h: delete duplicate macro definition.
7080 * new file atof-ns32k.c copied from hack's last unreleased gas.
7082 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7084 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7087 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7088 ChangeLog's prior to this are sketchy at best. I have logs.
7089 They just aren't ChangeLogs.
7093 version-control: never
