149 section symbol, not C_LABEL.
151 * config/tc-mips.c (mips_ip): Permit a modifier in 'o' case, and

203 * read.c (emit_expr): Use memset to zero out memory, rather than
204 going through md_number_to_chars. This permits handling symbolic
205 arguments when the size is larger than sizeof (valueT), if

258 (control_regs): New pointer.
259 (m68k_ip): Use control_regs instead of testing CPU every time.

706 directory, and specify PSECT attributes explicitly to linker.
707 Also added missing label.
708 * Makefile.in (stamp-mk.com): Reference new variable
709 VMS_OTHER_OBJS for list of non-local object files, instead of

797 don't spew remainder of input file in error message.
798 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
799 message with reloc type and try to process remainder of file.

859 to make it pcrel_offset.
860 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

892 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
893 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

913 -non_shared to use NO_PIC (this is how the Irix 5 assembler
914 works). Do not permit -G with SVR4_PIC.

963 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
965 * write.c (symbol_table_frozen): New variable, to be set after
966 bfd_set_symtab is called.
967 (dump_section_relocs): Note whether a symbol is a section symbol
969 (adjust_reloc_syms): For now, always supply an absolute symbol for
970 fixups without symbols but not yet `done'. Use section_symbol to
971 get the symbol, instead of going directly for abs_symbol.
972 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
973 reloc is not a section symbol and is not in the symbol table.
974 (set_symtab): New function, broken out from write_object_file.
975 Counts symbol table instead of relying on an earlier count.
976 (write_object_file): Call set_symtab, but do it after potentially
977 invoking the *_frob_file macros. Don't bother counting symbols.
978 Call symbol_remove, instead of expanding it in place. Moved the
979 conditionalized `object_file_size' declaration down to
980 conditionalized block where it's used. When using the absolute
981 symbol for a fixup without a symbol, set sy_used_in_reloc.
982 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
983 the correct symbol for the absolute section.
985 * subsegs.c (section_symbol): Use symbol_new instead of
986 symbol_make, since we may want it to go into the symbol table.
987 Make the new symbol have internal linkage. If
988 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
989 symbol with the newly created GAS symbol.
990 (obj_sec_sym_ok_for_reloc): Default to always returning 0.

996 (in_signed_range): New function.
998 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
999 (sparc_ip, label "immediate"): Reject constants for pcrel
1000 instructions only if the relocation type indicates a "call"
1001 instruction and the offset is within range of a "jmpl %g0". If
1002 it's not in range, use the absolute section symbol plus an offset.
1003 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1005 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1007 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1010 * configure.in: Eliminated all targets using obj-coff but not
1011 defining BFD_ASSEMBLER; I think all such targets that are
1012 supported will be matched by real CPU-OS combinations earlier in
1014 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1015 some comments about the dpx2 configuration, but left it disabled,
1016 since it couldn't be reached before.
1017 (target a29k-amd-ebmonold): Deleted.
1019 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1027 the 'j' operand if there are no further alternatives for this
1030 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1031 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1032 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1034 * config/tc-mips.c (mips_align): Take new argument, label, and use
1035 it instead of global insn_label.
1036 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1037 call to mips_emit_delay and pass it to mips_align.
1039 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1041 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1043 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1044 argument to a .callinfo directive. Don't loop forever on errors.

1052 S_IS_EXTERNAL when deciding whether to discard a symbol.
1054 * config-gas.com: Scan Makefile.in, not version.c, for current
1055 version number. Delete all versions of temp files when finished
1056 with them. Create config.h.

1059 values to reduce number of lookups with S_GET_VALUE. Skip debug
1060 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1061 holger@botbso.rhein-main.de.)
1062 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1063 field. (Also from Holger Teutsch.) Watch for a would-be register
1064 mask that spans frags.
1066 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1067 this_base, not line_base. (Patch from Andreas Arens,

1071 look local if they're exported or undefined. Used to be done for
1074 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

3205 default is to assume production environment, and reject configs
3206 still being worked on. Mark Elf configurations (except sparc and
3207 i386) as developmental. Deleted cases matching some generic names
3208 in favor of more specific names. (E.g., when we get Alpha

3234 into a few places. Make all functions and variables which
3235 are only used within tc-hppa.c static. PARAMize all functions.
3236 Add comments to functions. Delete unused functions, variables,
3237 #defines, etc. Delete unused members within structures. Delete
3238 ldil;ble hacks -- it is believed they were installed to work
3239 around old gas bugs. Avoid using mixed case for local
3240 functions, variables, and structures. Fix formatting problems
3241 not found by GNU-indent. Add FIXME notices for things which
3242 should be worked on the near future. Delete lots of old

4405 * Extensive changes to permit symbols to contain any expression
4406 type and to delay the computation of the expression until the
4407 value is actually needed. This permits setting symbols to values
4408 calculated based on object code size. Expressions were changed to
4409 no longer be in a section, to stop the overloading of segment and
4410 expression type that previously occurred.
4412 * as.c (big_section, pass1_section, diff_section, absent_section):
4414 (expr_section): Added (used for dummy symbols which hold

4498 (previous_section, previous_subsection): New vars.
4499 (obj_elf_section): Save current place in case DWARF code wants us
4500 to pop back to it. Handle unquoted section name as well as quoted
4501 section name. Don't crash on invalid strings.
4502 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

4539 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
4541 * read.c (float_cons): Simplified parsing logic. If
4542 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

4562 (macro): Call mips_emit_delays before setting mips_noreorder.
4563 Increment and decrement mips_noreorder rather than using

4590 (omagic): Removed unused variable.
4592 * Preliminary support for m88k-coff.

4611 * Removed sy_forward and replaced it with an undefined expression
4612 as the value of a symbol.
4613 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
4614 sy_resolved and sy_resolving single bit fields.
4615 * symbols.c (symbol_new): Don't initialize sy_forward field.
4616 (resolve_symbol_value): New function to adjust symbol value by
4617 fragment address, using recursion to resolve forward symbols.

4619 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
4620 expression rather than setting symbolP->sy_forward.
4621 * write.c (write_object_file): Use resolve_symbol_value on
4622 symbols, keeping the common case (the old behaviour) inline.

5649 than ECOFF line number information.
5650 (obj_ecoff_stab): Accept non-zero values for stabs line number.

5709 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
5710 the bottom (make expands variables in dependencies when the
5711 dependencies are read, not when they are used).
5713 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5714 a29k .bss section; the mondfe program doesn't like it.

5735 source directory, if that's not the current directory.
5737 * configure.in (per-host): Accept MIPS host with BSD version

5758 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
5759 process relocs if there aren't any relocs to process. Avoids
5760 malloc/free bug on SCO too.
5762 * as.h: Move local include files below system include files, to
5763 avoid some redefinition complaints on some systems.
5764 (const, volatile): Don't need these conditionally defined if we
5765 use CONST and VOLATILE from ansidecl.h.
5766 (seg_name): Use CONST, not const.
5768 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5770 * config/tc-mips.c: Reindented to GNU standards.
5772 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
5774 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5775 (fixup_segment): Add a29k special case; the linker is not prepared
5776 to see a segment offset here.
5778 * app.c (do_scrub_next_char): Added new state, 10, modifying state
5779 9 to only keep a space in between identifier characters.
5781 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5783 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5784 srcdir, might be in objdir.
5786 * doc/Makefile.in: dvi depends on as.dvi

5804 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
5805 bignums, but don't emit error message.
5807 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
5809 * Makefile.in (targ-cpu.o): Depend on config.h.
5811 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5813 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5814 dropping a space immediately following an identifier.
5815 * expr.c, write.c: Rewrote assert expressions to not use multiple
5816 lines; I don't think that can be done portably.
5817 * config/tc-mips.c (macro): Use $AT if target register is zero in
5818 load instruction, which it can be for a floating point load.
5820 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5828 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
5831 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
5832 z8k-opc.h, not z8k.h.
5834 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
5837 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5839 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
5841 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5843 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5844 to be on a single line.

5892 prototypes for all static functions. Moved existing minimal
5893 debugging format support info #ifndef OBJ_ECOFF blocks.
5894 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
5895 does not support a non sign extended high 16 bits reloc. Adjusted
5896 all callers accordingly.
5897 (tc_get_register): Renamed from get_register, and made non-static.
5899 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5942 * make-gas.com: Find obstack.obj if it's not in the current
5944 * read.c (s_ignore): Don't declare is_end_of_line. It's
5945 redundant, and triggers a VMS gcc compiler bug.
5947 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5948 current segment as an argument. (Ignored in all cases but VMS.)
5949 All callers and definitions changed.

5967 argument to s_ignore. Put "#if 0" around unused code.
5968 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5969 Call elf_xstabs for .stabs and .xstabs operators.
5971 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5973 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5976 * configure.in: mips-bsd configuration was missing format spec.
5979 * Makefile.in (Makefile): Depends on configure.in.
5981 * config/tc-mips.c (append_insn): Don't check for alignment of
5982 frag in memory; alignment of instructions in section is a separate

6002 * config/tc-sparc.c (s_xword): Now call big_cons, so large
6003 constants are accepted, but symbolic values are not. GCC will not
6004 generate the latter currently.
6006 * frags.c (frag_init): New function.
6007 (zero_address_frag, bss_address_frag): Now initialized at run
6009 * as.c (main): Call frag_init.

6041 referencing symbol structure members.
6042 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
6044 * as.h (struct frag): Reordered a couple of fields for better

6052 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
6053 (fixup_segment): Make sure common-section symbols get treated the
6054 same as undefined symbols.
6055 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
6056 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
6058 * write.h (fix_new): Update prototype.
6060 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
6061 md_section_align, md_undefined_symbol): Don't provide prototypes
6062 if these are defined as macros.
6063 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
6066 * symbols.c (symbol_new): Argument NAME is now pointer to const.
6067 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
6068 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

6084 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
6085 new section/subsection.
6087 * read.c: Don't include ctype.h.
6088 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
6089 for now; should be machine-dependent.
6091 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
6092 targets, forcing BFD use.
6094 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6096 * config/tc-sparc.c: Use PARAMS macro for static function

6262 latter, instead of selecting with preprocessor conditionals.
6264 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
6266 * configure.in: recognise all sparclite variants

6276 * expr.c (operand): If character other than comma or newline is a
6277 logical end-of-line character, use the newline case.
6278 From Eric Youngdale:
6279 (operand): Set X_add_number field for floating-point numbers.
6280 (operand): Treat zero byte as end-of-operand.
6282 * configure.in (per-target): Look for with_bfd_assembler option.
6283 For now, only accept "no", until the merge is done.
6285 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
6286 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

6292 * expr.c: Add "const" modifier to hex_value.
6293 * symbols.c: Finish conversion to S_* macros in the VMS only
6294 parts of the program. Add "const" modifier to
6295 md_[long,short]_jump_size. Remove declaration of const_flag
6296 (which will be declared in obj-vms.h).
6297 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6298 Fix arguments to VMS_write_object_file.
6299 * config-gas.com: New file. Script for VMS systems to set up the
6300 configuration to build gas for VMS, and create config.status.
6301 * make-gas.com: Redone to work with new scheme.
6302 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
6304 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

6307 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6308 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6309 types of malformed stabs. Change parsing algorithm so that we are
6310 more certain of having all of the information that we need on hand.
6311 * obj-vms.c (final_forward_reference): New function, used to help
6312 resolve the data types of as many struct elements as possible
6313 when some part of the struct is not fully defined by the compiler.

6316 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6317 as symbols as well in the object file. Look for external functions

6319 g++ compiler is incapable of doing this.
6320 * tc-vax.c: Add '1' option for backward compatibility with older GCC
6322 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
6323 * input-scrub.c (as_where): Fix bug where as would crash if we did not
6324 have the name of the source file yet.
6325 * config/ho-vms.h: define HO_VMS, not HO_VAX.
6327 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
6329 * read.c (s_data): Always use "data_section", since it'll map to
6330 SEG_DATA or SEG_E1 if needed.
6331 (s_lcomm): Likewise with bss_section.
6332 (s_fill): Use memset, not bzero.
6334 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

6356 (big_section, reg_section, pass1_section, diff_section,
6357 absent_section, text_section, data_section, bss_section): If
6358 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
6359 mapping to segT enum values.
6360 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6361 if these are used or defined, if BFD_ASSEMBLER.
6362 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6363 subseg_new split into two functions.
6364 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6366 * as.h (volatile): Don't define if already defined.
6367 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6369 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
6370 declare with format attribute for -Wformat checking.
6372 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
6374 * app.c, config/tc-*.c: Don't include read.h, since it is already
6377 * These are based on patches from Minh Tran-le
6378 <mtranle@paris.intellicorp.com>.
6379 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
6380 obj_format coffbfd and gas_target i386coff for target.
6381 (i[34]86-*-isc*): New host (uses sysv).
6382 * config/i386aix.mt: Removed (no longer used).
6383 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
6385 (LDFLAGS): Added, defined as -shlib.
6386 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
6387 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6388 (DOT_LABEL_PREFIX): Define.
6389 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
6390 name rather than L0\001.

6402 (size_section): Restored sanity check.
6403 (do_relocs_for): Base section address on s_paddr rather than
6404 computing it. Adjust a29k R_IHIHALF special case to account for
6405 section paddr (used to require paddr to be zero). If there are no
6406 reclos, set s_relptr to 0. Set relocation size in object_headers.
6407 (fill_section): Always set s_vaddr here, removing
6408 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6409 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6410 Set STYP_INFO for .comment.
6411 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6412 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6414 H_{SET,GET}_* macros.
6415 (do_linenos_for): Set lineno size in object_headers.
6416 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6417 set s_vaddr here. If string_byte_count remains 4, set it back to
6418 0, and only write strings out if there are some. Call
6419 fill_section before do_relocs_for and do_linenos_for.
6420 (obj_coff_section): Handle optional quoted second argument giving
6421 section characteristics.
6422 (obj_coff_bss): Added to handle .bss.
6423 (obj_coff_ident): Added to handle .ident (puts string in .comment

6443 (do_scrub_next_char): For \", return " not '.
6444 (symbol_chars): Now const.
6446 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
6447 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6449 * config/obj-coff.h: Don't use #elif.
6451 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6452 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6454 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
6456 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6476 SEG_BSS, fill with NOP_OPCODE.
6477 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6478 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6479 using ZERO_BASED_SEGMENTS.
6480 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6481 never set segment address for SEG_E2 (.bss) and don't write out
6482 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6483 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6484 definitions, and don't merge tags with non-tags. Check for .bf
6485 rather than just checking whether the second character is b and
6486 the third character is f.
6487 (obj_coff_val): gcc can generate values which we don't handle
6488 correctly; discard information for now, since it only affects the
6489 debugging information.
6490 (tag_find_or_name): Don't insert tags in the symbol table.
6491 (yank_symbols): Don't merge labels.
6492 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6512 power-of-two alignment for .align.
6514 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6515 and leave everything else alone.

6638 could be doing emulation.
6640 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6643 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6756 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6757 #elif, since it is not supported by old compilers.
6758 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6759 couple of expressions in tc-m68k.c.
6761 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6763 * read.c (cons): If NO_RELOC is defined, use it.

6789 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6790 sections starting from zero, rather than making them consecutive.
6791 This makes subsequent reloc calculations easier, esp if the object
6792 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6793 allocate lcomm in .data rather than in .bss. It seems that some
6794 tools can't cope with a non-zero sized bss before linkage.
6796 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6798 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6817 * Makefile.in (install): if $(tooldir) exists, install as in
6820 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6822 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6823 .word is < -32768 or > 32767. The -J flag causes the error to be
6824 ignored. This is to catch over-sized switches generated by gcc on
6825 systems which don't support the broken .word hack.
6826 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6827 write.c (fixup_segment): check for signed .word overflow if
6828 WARN_SIGNED_OVERFLOW_WORD.
6830 * write.c (fixup_segment): fixed missing parens in expression

6847 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6849 * input-scrub.c (input_scrub_push): call input_file_begin, not
6851 messages.c (as_perror): print ": " between the passed in error and
6852 the strerror, like perror does.

6857 From Steve Chamberlain:
6858 Makefile.in: Handle m68*-*-coff*.
6859 read.c, read.h: add mult argument to s_space
6861 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6862 Motorola and MIT syntax; gas can now assemble either type of
6864 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6870 (write_object_file) call fixup_mdeps
6871 (fixup_segment) set fx_subsy to 0.
6872 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6874 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6877 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6879 * Makefile.in (LIBS): Include opcode library.
6881 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6904 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6906 * config/tc-m68k.c (init_table): Now const. Always include 68851
6907 data, so that "bc" is available to 68040 cache instructions.
6908 Added "tt0", "tt1", and 68ec030 variants.
6909 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6910 (enum _register): Added TT0, TT1.
6911 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6912 line number correctly in "internal error" messages. Don't print
6913 architecture-mismatch message for operand errors.
6915 From Colin Smith (colin@wrs.com):
6916 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6917 than install_operand.

6933 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6934 so that we can assemble hand-written libgcc code.

6938 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6939 has already been formatted (but may still contain %-characters).
6942 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6944 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6945 written with indirection on the last two operands, which can be
6946 either data or address registers. Added a new operand type 'r'
6947 which accepts either register type. Added '(' to notend stuff in
6948 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6950 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6966 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6967 their not having symbols associated.
6969 * tc-i960.c (norelax, instrument_branches): Default initializer is
6971 (linkrelax): Delete variable definition.

6995 being used with args swapped, causing occasional lossage when
6996 refilling buffers after an include file.

7006 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
7007 selected architecture, print a message saying so and listing what

7145 * write.c (write_object_file): keep the fix_tail clean, which
7146 fixes a bug in -R where relocations were being lost.

7197 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7199 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7200 where gcc looks for it.
7202 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7204 * Makefile.in: Changed some lines to be less confusing for some

7270 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
7272 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
7274 * expr.c (operand): if can't work out what sort of operand it is,
7275 then look through FLT_CHARS for a hint.
7277 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7279 * Makefile.in, configure.in: removed traces of namesubdir,
7280 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7281 copyrights to '92, changed some from Cygnus to FSF.
7283 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7284 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7285 copyrights to '92, changed some from Cygnus to FSF.
7287 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7289 * expr.c: If an expression is single comma, then return with
7290 SEG_ABSENT rather than an error - since the sparc front end does
7291 really strange things with things like fbge,a
7293 * as.h: include bfd.h if using many sections
7294 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7295 local labels didn't work.
7296 * listing.c (list_symbol_table): don't core dump when there's no
7298 * write.c, write.h: call fix_new with the right number of args on
7300 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7303 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7305 * app.c: MRI compatibility - allow single quote to start a string.
7306 * as.c: fix typo recently introduced.
7307 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7308 * expr.c: Much rewriting, to accomodate MRI syntax for
7309 expressions. Also easier to read now.
7310 * listing.c: Put back defuns
7311 * read.c: modified to accept MRI syntax, put back listing pseudo
7312 ops so that an assembler built with NO_LISTING ignores list ops
7314 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7315 machine is a SPARC or a 29K.
7316 * config/obj-aout.c: added s_sect pseudo op
7317 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7318 fill in the timestamp.
7319 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7320 anymore, define all the relocs which the tc-<x> bit will use so we
7321 can translate from them to the coff types.
7322 * config/tc-a29k.c: reloc_type isn't ane enum any more
7323 * config/tc-m68k.c: Added NO_RELOC definition.
7325 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7327 * Makefile.in: put header files before C source for TAGS; remove
7328 references to non-existent syscalls.h.
7330 * read.c, write.c subsegs.c: back out the .bss changes.
7332 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7334 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7338 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7340 * symbols.c (local_label_name): symbols now start with ^A.
7342 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7343 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7344 generate these sections. .align: will use NOP_OPCODE or 0
7345 for padding. This is just for being nice to the
7348 * expr.c (operand): changed to generate local label "\001L0"
7349 starting with a ^A so that it is recognized as a local label.
7351 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7353 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7354 i/o opcodes - inb, inw, outb and outw. string manipulation with
7355 att syntax - scmp, slod, smov, ssca, ssto.
7357 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7358 to just after .file .
7360 In obj_crawl_symbol_chain() where it tries to put the external
7361 symbols apart, with the condition:
7362 (!S_IS_DEFINED(symbolP) &&
7363 !S_IS_DEBUG(symbolP) &&
7364 !SF_GET_STATICS(symbolP))
7365 it was moving too many symbols out. So I switch it back to the
7367 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7369 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7370 so that we don't use the F_RELFLG which make the linker complain
7371 that somebody has stripped the relocation info.
7373 Also, the AIX ld program require that the relocation table
7374 is sorted by r_vaddr like the standard ATT assembler does.
7376 [he also changed the sizeof(struct ...)'s into the coff
7377 style FOOSZ macros. I'm not sure this is right, but I can't
7378 remember why. xoxorich.]
7380 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7382 * Makefile.in, configure.in, doc: use the doc. Build it, install

7387 * read.c: white space and comments only.
7389 * configure.in: use the new atof-ns32.c for ns32k.
7391 * write.c: comment change only.
7393 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7394 aren't yet integrated.
7396 * tc-i860.[hc]: blew off the dust. Something must still be done
7397 about conflicting relocation types.
7399 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7402 * tc-i960.c, tc-sparc.c: white space and comments only.
7404 * tc-a29k.h: delete duplicate macro definition.
7406 * new file atof-ns32k.c copied from hack's last unreleased gas.
7408 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7410 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7413 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7414 ChangeLog's prior to this are sketchy at best. I have logs.
7415 They just aren't ChangeLogs.
7422 version-control: never
