3984         size is at most 16 bits.  This is to catch cases like "add
3985         $0xffc0,%ax" where we don't know the size, and thus that the
3986         immediate can be represented as Imm8S until after parsing the

4021         port is arm-wince.

4043         (i386_intel_memory_operand): After finding a segment override,
4044         check again for no `[' before looking for a displacement.  Bomb if

4062         displacements and immediates.  Combine output of Disp16 with
4063         Disp32.
4064         (md_assemble): Don't try to fix broken UNIXWARE_COMPAT opcodes
4065         when in intel mode by (not) reversing fsub and fdiv operands
4066         before the template search.  This fails for single operand
4067         shorthand forms of the instruction, and if UNIXWARE_COMPAT is
4068         undefined.  Instead fix the base_opcode after we've found the
4069         template.  Move base_opcode xor with found_reverse_match from
4070         opcode output code to before this fix so we test for the correct
4071         opcodes.
4072         (md_assemble): Don't use strcmp when deciding to ignore the suffix
4073         check in intel mode.  Instead compare opcodes.

4240
4241         * read.c (s_rept): Call do_repeat, which abstracts the repeat
4242         logic.
4243         (do_repeat): New.  Abstract repeat logic so that a "break" can be
4244         implemented.
4245         (end_repeat): New.  Provide support for a "break" out of the
4246         repeat loop.

4278         * listing.c (calc_hex): Account for octets vs bytes when
4279         printing addresses/offsets.
4280         (print_lines) Ditto.  Also, if LISTING_WORD_SIZE is not 1, and
4281         target is little-endian, print the octets in a word in big-endian
4282         order so that the display looks like a proper hexadecimal number,
4283         instead of having the octets reversed.
4284         * read.c (do_align): When recording alignment, alignment power
4285         should be in terms of target bytes (minimum addressible unit)
4286         instead of octets.
4287         (do_org) Convert ORG target address (byte) argument into an
4288         octet offset when generating a variable fragment.
4289         * symbols.c (resolve_symbol_value): Symbol final value
4290         converted to a target address offset (bytes) from its octet offset.
4291         * config/obj-coff.c (coff_frob_symbol): Symbol target address
4292         offset (bytes) is adjusted by the frag offset (octets) converted
4293         to bytes.
4294         (coff_frob_section) Section alignment power is in terms of bytes;
4295         convert it to an octet alignment power when calculating size (and
4296         size mask) in octets.  Don't modify the section size in order to
4297         "align" it for TI COFF, since that format has a different method
4298         for storing alignment information.
4299

4301

4316         New macro.
4317         * config/tc-ppc.c (ppc_fix_adjustable): Don't look at the frag
4318         of a symbol when we really care about its value.

4326
4327         * config/tc-arm.c (armadjust_symtab): If the assembler is in
4328         Thumb mode but the label seen was not declared as '.thumb_func'
4329         then set the ST_INFO type to STT_ARM_16BIT mode.   This allows
4330         correct disassembly of Thumb code bounded by non function labels.
