        from here..
        (md_assemble): To here, before template operands are matched.
        Also ensure a constant immediate is sign extended when we know the
        size is at most 16 bits.  This is to catch cases like "add
        $0xffc0,%ax" where we don't know the size, and thus that the
        immediate can be represented as Imm8S until after parsing the
        register operand.
        (i386_displacement): Similarly sign extend 16 bit constant
        displacements.
        (md_assemble): Relax 16-bit jump constant range check to suit sign

        earlier "SHORT" change.
        (md_assemble): When determining suffix from Regs, exclude
        InOutPortReg.

        port is arm-wince.

        target os arm-wince.

        COFF flavour.

        * config/tc-sh.c (md_begin): sh-pe target is little endian.
        * config/tc-sh.h (SUB_SEGMENT_ALIGN): If using a BFD
        assembler, just set the alignment to 4.

        * config/te-wince-pe.h: New file for WinCE targets.  Define
        TE_WINCE.

        * config/tc-i386.c (union i386_op): New.
        (struct _i386_insn): Delete disps[], imms[], regs[].  Add op[].
        Throughout file replace occurences of disps[n], imms[n], regs[n]
        with equivalent op[n].disps, op[n].imms, op[n].regs.  Simplify
        intel mode operand swapping.  Add assert in regKludge and
        fake_zero_displacement code.  Test i.types[n] when outputting
        displacements and immediates.  Combine output of Disp16 with
        Disp32.
        (md_assemble): Don't try to fix broken UNIXWARE_COMPAT opcodes
        when in intel mode by (not) reversing fsub and fdiv operands
        before the template search.  This fails for single operand
        shorthand forms of the instruction, and if UNIXWARE_COMPAT is
        undefined.  Instead fix the base_opcode after we've found the
        template.  Move base_opcode xor with found_reverse_match from
        opcode output code to before this fix so we test for the correct
        opcodes.
        (md_assemble): Don't use strcmp when deciding to ignore the suffix
        check in intel mode.  Instead compare opcodes.

        and KEEP_WHITE_AROUND_COLON.

        logic.
        (do_repeat): New.  Abstract repeat logic so that a "break" can be

        (end_repeat): New.  Provide support for a "break" out of the
        repeat loop.
        * read.h: Add prototypes for new functions.

        Distinguish between octets and bytes in field descriptions.
        * listing.c (calc_hex): Account for octets vs bytes when
        printing addresses/offsets.
        (print_lines) Ditto.  Also, if LISTING_WORD_SIZE is not 1, and
        target is little-endian, print the octets in a word in big-endian
        order so that the display looks like a proper hexadecimal number,
        instead of having the octets reversed.
        * read.c (do_align): When recording alignment, alignment power
        should be in terms of target bytes (minimum addressible unit)
        instead of octets.

        octet offset when generating a variable fragment.

        offset (bytes) is adjusted by the frag offset (octets) converted
        to bytes.
        (coff_frob_section) Section alignment power is in terms of bytes;
        convert it to an octet alignment power when calculating size (and
        size mask) in octets.  Don't modify the section size in order to
        "align" it for TI COFF, since that format has a different method
        for storing alignment information.

2000-02-01  Timothy Wall  <twall@cygnus.com>

        * stabs.c (generate_asm_file): Escape backslashes in stabs file

        * config/tc-arm.c (reg_table): Add support for ATPCS register

        operands passes to instruction are more than the spec.

        Thumb mode but the label seen was not declared as '.thumb_func'
        then set the ST_INFO type to STT_ARM_16BIT mode.   This allows
        correct disassembly of Thumb code bounded by non function labels.
