        * Extensive changes to permit symbols to contain any expression
        type and to delay the computation of the expression until the
        value is actually needed.  This permits setting symbols to values
        calculated based on object code size.  Expressions were changed to
        no longer be in a section, to stop the overloading of segment and

        undefined symbols.

        * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

        use new macro tc_frob_label.
        * config/tc-hppa.h (tc_frob_label): Define.

        * config/tc-mips.c: Many changes to support simple assembler
        optimization.

        M_L_DOB and M_L_DAB, since append_insn will not insert a NOP.
        (md_atof): Handle floating point numbers correctly for both
        big and little endian targets.
        (s_align, s_cons): Call mips_align rather than frag_align.

        with a warning.

        * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
        by md_pcrel_from if we are relocating against a symbol (we still
        need md_pcrel_from for a PC relative relocation within the same
        file).
        * config/tc-m88k.c (md_pcrel_from): Corrected return value.
        (omagic): Removed unused variable.

        * Preliminary support for m88k-coff.

        expressions.
        * config/obj-coffbfd.c (obj_pseudo_table): If TC_M88K, accept
        "sdef" as a synonym for "def".
        * config/obj-coffbfd.h: If TC_M88K, include coff/m88k.h and set
        TARGET_FORMAT.
        (S_IS_LOCAL): Any symbol which includes \001 in the name is local.
        * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
        m88k port up to date, and to add COFF support.

        * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
        process relocs if there aren't any relocs to process.  Avoids
        malloc/free bug on SCO too.

        * as.h: Move local include files below system include files, to
        avoid some redefinition complaints on some systems.
        (const, volatile): Don't need these conditionally defined if we

Wed Mar 24 02:16:22 1993  david d `zoo' zuhn  (zoo at poseidon.cygnus.com)

        * Makefile.in: add dvi target; as-$(config).texinfo might live in
        srcdir, might be in objdir.

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

Mon Mar 15 12:17:28 1993  Ian Lance Taylor  ([email protected])

        * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
        by the section vma.

        symbol.

Fri Mar 12 18:33:36 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

Fri Mar 12 12:00:07 1993  Ian Lance Taylor  ([email protected])

        * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

        (main): Call strdup instead.

        * configure.in: Handle all 68300 series chips.
        * config/tc-m68k.c: Include config.h.
        (md_assemble): Assume TARGET_CPU is defined.  Accept some 68300
        series cpus as defaults.

        * config/tc-mips.c: Rearranged for ECOFF support.  Added
        prototypes for all static functions.  Moved existing minimal
        debugging format support info #ifndef OBJ_ECOFF blocks.
        (macro_build_lui): Eliminated sign_extend argument, because ECOFF
        does not support a non sign extended high 16 bits reloc.  Adjusted
        all callers accordingly.

Wed Mar  3 10:41:46 1993  Ken Raeburn  ([email protected])

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

        * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
        current segment as an argument.  (Ignored in all cases but VMS.)
        All callers and definitions changed.

Tue Mar  2 11:56:19 1993  Ian Lance Taylor  ([email protected])

        * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

        routines.
        (obj_elf_xstab): New routine.
        (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
        argument to s_ignore.  Put "#if 0" around unused code.
        (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
        Call elf_xstabs for .stabs and .xstabs operators.

        * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".

        * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
        present.

        * configure.in: mips-bsd configuration was missing format spec.
        Should use aout.

        * Makefile.in (Makefile): Depends on configure.in.

        * config/tc-mips.c (append_insn): Don't check for alignment of
        frag in memory; alignment of instructions in section is a separate
        matter.

        * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
        C availability.

        * listing.h: Always provide function declarations, not macros, so
        pcc won't lose.

        * tc.h (md_operand, md_convert_frag, tc_headers_hook,
        md_section_align, md_undefined_symbol): Don't provide prototypes
        if these are defined as macros.
        (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and

        md_relax_table): Use default zero initialization.
        (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
        latter, instead of selecting with preprocessor conditionals.

Thu Jan  7 08:58:21 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

        * configure.in: recognise all sparclite variants

Thu Jan  7 05:25:25 1993  Ken Raeburn  ([email protected])

        * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
        accidentally changed to use subseg_change where it should have
        been subseg_new.

Tue Jan  5 08:42:16 1993  Ken Raeburn  ([email protected])

        * expr.c (operand): If character other than comma or newline is a
        logical end-of-line character, use the newline case.
        From Eric Youngdale:
        (operand): Set X_add_number field for floating-point numbers.
        (operand): Treat zero byte as end-of-operand.

        * configure.in (per-target): Look for with_bfd_assembler option.
        For now, only accept "no", until the merge is done.

        Merged changes from Eric Youngdale ([email protected]):
        * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
          config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
        * read.c: Finish conversion to S_* macros in the VMS only
          parts of the program. Add "const" modifier to hex_value.
        * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
          "ifdef OBJ_VMS".
        * expr.c: Add "const" modifier to hex_value.
        * symbols.c: Finish conversion to S_* macros in the VMS only
          parts of the program.  Add "const" modifier to
          md_[long,short]_jump_size. Remove declaration of const_flag
          (which will be declared in obj-vms.h).
        * write.c: Add "const" modifier to md_[long,short]_jump_size.
          Fix arguments to VMS_write_object_file.
        * config-gas.com: New file.  Script for VMS systems to set up the
          configuration to build gas for VMS, and create config.status.
        * make-gas.com: Redone to work with new scheme.
        * obj-vms.c: Patch to fix bug where we were not correctly parsing the
          stabs directives.
        * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
          will swap bytes if needed on a big endian system.  Use throughout
          as needed.
        * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
        * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain

          more certain of having all of the information that we need on hand.
        * obj-vms.c (final_forward_reference):  New function, used to help
          resolve the data types of as many struct elements as possible
          when some part of the struct is not fully defined by the compiler.
        * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
          stabs directives.
        * obj-vms.c (VMS_write_object_file): Define all vtable psects
          as symbols as well in the object file.  Look for external functions
          that start with "__vt.", and turn them into variables, since the
          g++ compiler is incapable of doing this.
        * tc-vax.c: Add '1' option for backward compatibility with older GCC
          versions.
        * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

Mon Jan  4 05:17:26 1993  Ken Raeburn  ([email protected])

        SEG_DATA or SEG_E1 if needed.
        (s_lcomm): Likewise with bss_section.
        (s_fill): Use memset, not bzero.

Thu Dec 31 04:29:27 1992  Ken Raeburn  ([email protected])

        * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
        (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

        absent_section, text_section, data_section, bss_section): If
        BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
        mapping to segT enum values.
        (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
        if these are used or defined, if BFD_ASSEMBLER.
        (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
        subseg_new split into two functions.
        (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

        * as.h (volatile): Don't define if already defined.

        NO_STDARG.
        (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
        declare with format attribute for -Wformat checking.

Wed Dec 30 10:18:57 1992  Ian Lance Taylor  ([email protected])

        * app.c, config/tc-*.c: Don't include read.h, since it is already
        included by as.h.

        * These are based on patches from Minh Tran-le
        <[email protected]>.
        * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
        obj_format coffbfd and gas_target i386coff for target.
        (i[34]86-*-isc*): New host (uses sysv).
        * config/i386aix.mt: Removed (no longer used).
        * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
        (MINUS_G): Removed.
        (LDFLAGS): Added, defined as -shlib.
        * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
        * config/te-sco386.h (LOCAL_LABEL): Don't define.
        (DOT_LABEL_PREFIX): Define.
        * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
        name rather than L0\001.
        * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
        local_bss_counter.
        * symbols.c, symbols.h (local_bss_counter): Removed.
        * write.c (write_object_file): bss no longer uses
        local_bss_counter.  Pass correct data and bss size to
        VMS_write_object_file.
        * config/obj-vms.c (VMS_write_object_file): Accept bss size as
        argument, rather than using local_bss_counter.
        * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
        * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.

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

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

        section).
        (obj_coff_lcomm): Put common symbols in .bss, not .data.
        (fixup_mdeps): Change to segment.  Call frag_wane after
        md_convert_frag.
        (fixup_segment): Explicitly check S_IS_COMMON before making 386
        adjustment (already happened only for common symbols, but this is
        clearer).
        * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
        * config/tc-i386.c (s_bss): Don't use if I386COFF.

        (tc_coff_sizemachdep): New function.
        * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
        compatibility.

        * app.c (app_push): Use memcpy, not bcopy.
        (do_scrub_next_char): For \", return " not '.
        (symbol_chars): Now const.

        * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
        and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".

        * config/obj-coff.h: Don't use #elif.

        * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
        have it.  (Reported by Noah Friedman, [email protected].)

Wed Dec 16 12:12:33 1992  Ian Lance Taylor  ([email protected])

        * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

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

        set segment address if ZERO_BASED_SEGMENTS.
        (obj_coff_section): Accept and ignore a trailing quoted string, as
        used in AT&T i386 syntax.
        (fixup_segment): Take segment as argument.  On the i386, adjust PC
        relative addends by the segment vaddr.
        * tc-i386.h: Define SUB_SEGMENT_ALIGN.
        * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
        * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

        all modified.

Tue Nov 10 09:49:24 1992  Ian Lance Taylor  ([email protected])

        * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

        * subsegs.h: add extern to segment_info declaration.

        * read.h: added extern declarations for comment_chars,
        line_comment_chars, and line_separator_chars.
        read.c, app.c: removed definitions of comment_chars,
        line_comment_chars, and line_separator_chars.

        * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
        still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
        the register name.

        putting them in the symbol table.
        * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

        comment_chars, line_comment_chars and line_seperator_chars
        consistently const, and always initialized them.  Included read.h.

Thu Nov  5 17:55:41 1992  Jim Wilson  ([email protected])

        * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
        constant will not fit in an immediate field.
        (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

Wed Nov  4 07:50:46 1992  Ken Raeburn  ([email protected])

        * obj-coff.c (callj_table): Delete global variable.
        (obj_emit_relocations): Define it locally here, and only if

        with a single set using PARAMS macro.

        * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
        of 2.

Wed Oct 28 08:52:34 1992  Ken Raeburn  ([email protected])

        * version.c: Put conditional "const" before version_string, not
        before dummy function for VMS.  Now version 1.91.03.

        bfd_close_all_done.

Tue Oct 20 12:18:08 1992  Ian Lance Taylor  ([email protected])

        * Support for i386-sysv.
        obj-coffbfd.c (do_relocs_for, write_object_file): set segment
        addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
        be used to set them all to zero as was done before.
        (fill_section): segment addresses now set in write_object_file.
        (fill_section): Don't set STYP_NOLOAD for .bss section.

        * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
        support for C source listings. (obj_coff_endef): look in the right
        part of the symbol for the symbol name

        * tc-m68k.c (get_num): make it work for all segments, not just the
        first three.

        * tc-z8k.c: lots of bug fixes

Tue Sep 29 10:51:55 1992  Ian Lance Taylor  ([email protected])

        * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
        #elif, since it is not supported by old compilers.
        ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
        couple of expressions in tc-m68k.c.

Mon Sep 28 21:18:24 1992  Ken Raeburn  ([email protected])

        * read.c (cons): If NO_RELOC is defined, use it.

        * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

Fri Sep 25 18:18:52 1992  Ian Lance Taylor  ([email protected])

        * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
        local labels to start with a .) and set REGISTER_PREFIX to %.
        tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

Fri Sep 25 17:53:43 1992  John Gilmore  ([email protected])

Tue Sep 22 13:02:07 1992  Sean Eric Fagan  ([email protected])

        * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
        sections starting from zero, rather than making them consecutive.
        This makes subsequent reloc calculations easier, esp if the object
        format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
        allocate lcomm in .data rather than in .bss.  It seems that some
        tools can't cope with a non-zero sized bss before linkage.
 
Tue Sep 22 15:10:51 1992  Ken Raeburn  ([email protected])

        * tc-m68k.c: Replace "enum m68k_architecture" with "int"
        throughout.  That enum no longer means what we thought it meant.

        * tc-m68k.c (md_assemble, md_parse_option): Handle new
        "-mno-688[58]1" options.

        * Makefile.in (install): if $(tooldir) exists, install as in
        $(tooldir)/bin.

Sun Sep 13 20:30:10 1992  Ian Lance Taylor  ([email protected])

        * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
        .word is < -32768 or > 32767.  The -J flag causes the error to be
        ignored.  This is to catch over-sized switches generated by gcc on
        systems which don't support the broken .word hack.
        as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
        write.c (fixup_segment): check for signed .word overflow if
        WARN_SIGNED_OVERFLOW_WORD.

        * write.c (fixup_segment): fixed missing parens in expression
        checking for byte or word overflow.

        * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
        obj-coffbfd.c (fixup_segment): check for signed .word overflow if
        WARN_SIGNED_OVERFLOW_WORD.

        * obj-coffbfd.c (fixup_segment): fixed missing parens in
        expression checking for byte or word overflow.

        * tc-i386.h : new coff defines

Thu Sep 10 09:23:15 1992  Ian Lance Taylor  ([email protected])

        * input-scrub.c (input_scrub_push): call input_file_begin, not
        input_scrub_begin.
        messages.c (as_perror): print ": " between the passed in error and
        the strerror, like perror does.

Wed Sep  9 11:06:25 1992  Ian Lance Taylor  ([email protected])

        * Makefile.in: use gas_target instead of modifying target_cpu.
        From Steve Chamberlain:
        Makefile.in: Handle m68*-*-coff*.

        * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
         Motorola and MIT syntax; gas can now assemble either type of
         file.
        tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
        From Steve Chamberlain:
        m68kcoff.mt: for m68k COFF.
        obj-coffbfd.c: (fixup_mdeps) added
         (size_section) removed bad sanity check
         (fill_section) added rs_machine_dependent case
         (write_object_file) call fixup_mdeps
         (fixup_segment) set fx_subsy to 0.
        obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
         handle m68k.
        tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
         pseudo ops.

        * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
        tc-i960.c (md_ri_to_chars): Always output bout object file in
        little endian byte order (used to use endianness of host).

Tue Aug 25 15:50:48 1992  Ken Raeburn  ([email protected])

        * config/tc-m68k.c (init_table): Now const.  Always include 68851
        data, so that "bc" is available to 68040 cache instructions.
        Added "tt0", "tt1", and 68ec030 variants.
        (md_assemble): Complain if 68000 (only) and 68881 are specified.
        (enum _register): Added TT0, TT1.
        (m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
        line number correctly in "internal error" messages.  Don't print
        architecture-mismatch message for operand errors.

        From Colin Smith ([email protected]):
        * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

        files, they might be included twice.

        * z8k.c, z8k.h, z8k.mt: z8000 support stuff

Mon Aug 24 12:45:43 1992  Ian Lance Taylor  ([email protected])

        * Makefile.in: defined TARGET_CPU for C code so that it can choose
        one element of a family.

        * tc-m68k.c: use TARGET_CPU to choose default cpu type.

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

Fri Aug 21 14:38:44 1992  Ken Raeburn  ([email protected])

        * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
        has already been formatted (but may still contain %-characters).
        (as_bad): Likewise.

Wed Aug 19 11:20:59 1992  Ian Lance Taylor  ([email protected])

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

Wed Aug 19 09:25:09 1992  Ken Raeburn  ([email protected])

        * as.h (enum _relax_state): Start off at one, not zero, to better
        catch uninitialized-variable errors.
        (linkrelax): Declare new variable.

        * messages.c (warning_count, error_count): Default initializer is
        sufficient.

        * write.c: Merged some declarations, using PARMS macro.
        (text_frag_root, data_frag_root, bss_frag_root, text_last_frag,
        data_last_frag): No longer static.
        (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
        defined, call it.  Change segments before calling fixup_segment.

        * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
        their not having symbols associated.

Mon Aug 17 15:09:56 1992  Steve Chamberlain  ([email protected])

        * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
        being used with args swapped, causing occasional lossage when
        refilling buffers after an include file.

Mon Aug 17 13:18:51 1992  Ken Raeburn  ([email protected])

        * messages.c (as_tsktsk): Use correct ANSI form for stdarg

        * config/tc-m68k.c (md_pseudo_table): fix the .align thing
        the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

Wed Aug  5 01:54:34 1992  John Gilmore  (gnu at cygnus.com)

        * tc-m68k.c (try_index):  Error if index scaling specified and
        assembling for an older CPU than a 68020.

        ancient or broken compilers.

        * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
        processor/opcode mismatch, so reword the error message.
        (md_assemble): If no CPU has been set (even if FPU/PMMU
        characteristics have been), default to 68020.  Don't need extra
        quotes around error string.

Fri Jul 31 12:26:34 1992  Jim Wilson  ([email protected])

        * read.c (potable): Revert sac's incorrect change made Jul 13.

        * expr.c (operand): if can't work out what sort of operand it is,
        then look through FLT_CHARS for a hint.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  ([email protected])

        * Makefile.in, configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

        * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced

Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * expr.c: If an expression is single comma, then return with
        SEG_ABSENT rather than an error - since the sparc front end does
        really strange things with things like fbge,a 

        * as.h: include bfd.h if using many sections
        * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
        local labels didn't work.
        * listing.c (list_symbol_table): don't core dump when there's no
        symbol there.
        * write.c, write.h: call fix_new with the right number of args on
        the H8.
        * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
        errors nices

Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * app.c: MRI compatibility - allow single quote to start a string.
        * as.c: fix typo recently introduced.
        * as.h : Don't include aout/reloc.h - it's not right for COFF!
        * expr.c: Much rewriting, to accomodate MRI syntax for
        expressions. Also easier to read now.
        * listing.c: Put back defuns
        * read.c: modified to accept MRI syntax, put back listing pseudo
        ops so that an assembler built with NO_LISTING ignores list ops
        rather than pukes.
        * write.c, write.h: fixs - only keep a reloc type in a fix if the target
        machine is a SPARC or a 29K.
        * config/obj-aout.c: added s_sect pseudo op
        * config/obj-coffbfd.c: lints, set the filehdr flags right and
        fill in the timestamp.
        * config/obj-coffbfd.h: Since we don't include aout/reloc.h
        anymore, define all the relocs which the tc-<x> bit will use so we
        can translate from them to the coff types.
        * config/tc-a29k.c: reloc_type isn't ane enum any more
        * config/tc-m68k.c: Added NO_RELOC definition.

Fri Feb 21 06:21:07 1992  K. Richard Pixley  ([email protected])

        * Makefile.in: put header files before C source for TAGS; remove
          references to non-existent syscalls.h.

        * read.c, write.c subsegs.c: back out the .bss changes.

        * obj-aout.c: do not include stab.gnu.h if NO_LISTING.

        * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

        * a.out.h: removed.

Fri Feb 21 01:08:48 1992  Minh Tran-Le ([email protected])

        * symbols.c (local_label_name): symbols now start with ^A.

        * read.c, subsegs.c, write.c obj-coff.c: added handling of
          `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
          generate these sections.  .align: will use NOP_OPCODE or 0
          for padding. This is just for being nice to the
          disassembler.

        * expr.c (operand): changed to generate local label "\001L0"
          starting with a ^A so that it is recognized as a local label.

        * as.c (perform_an_assembly_pass): zero bss_fix_root, too.

        * tc-i386.c: tc-i386.c: added handling of the following opcodes:
          i/o opcodes - inb, inw, outb and outw.  string manipulation with
          att syntax - scmp, slod, smov, ssca, ssto.

        * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
          to just after .file .

          In obj_crawl_symbol_chain() where it tries to put the external
          symbols apart, with the condition:
            (!S_IS_DEFINED(symbolP) &&
             !S_IS_DEBUG(symbolP) &&
             !SF_GET_STATICS(symbolP))
          it was moving too many symbols out. So I switch it back to the
          condition:
            (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))

          In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
          so that we don't use the F_RELFLG which make the linker complain
          that somebody has stripped the relocation info.

          Also, the AIX ld program require that the relocation table
          is sorted by r_vaddr like the standard ATT assembler does.

          [he also changed the sizeof(struct ...)'s into the coff
          style FOOSZ macros.  I'm not sure this is right, but I can't
          remember why.  xoxorich.]

Fri Feb 21 01:08:48 1992  K. Richard Pixley  ([email protected])

        * Makefile.in, configure.in, doc: use the doc.  Build it, install
          it, clean it, etc.

Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)

        * read.c: white space and comments only.

        * configure.in: use the new atof-ns32.c for ns32k.

        * write.c: comment change only.

        * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
          aren't yet integrated.

        * tc-i860.[hc]: blew off the dust.  Something must still be done
          about conflicting relocation types.

        * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
          real thing.

        * tc-i960.c, tc-sparc.c: white space and comments only.

        * tc-a29k.h: delete duplicate macro definition.

        * new file atof-ns32k.c copied from hack's last unreleased gas.

Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)

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