* config/tc-i386.c (mode_from_disp_size): Disp16 is mode 2.
	(i386_operand): Simplify checks for valid base/index combinations.
	Disallow `in 4(%dx),%al'.

	* config/tc-i386.c (struct _i386_insn): Make regs, base_reg, and
	index_reg const.
	(add_prefix): Change parameter from char to int.

	* config/tc-i386.h (Ugh): Define opcode modifier.
	* config/tc-i386.c (md_assemble): Print warnings for Ugh insns.

	* config/tc-i386.c (md_assemble): Rewrite MATCH and
	CONSISTENT_REGISTER_MATCH macros to check register types more
	thoroughly.  Check for illegal suffix/operand combinations
	when matching insns with operands.  Handle new `s' suffix, and
	associated FloatMF opcode modifier for float insns with memory
	operands.
	* config/tc-i386.h (FloatMF): Define new opcode modifier.
	(No_sSuf, No_bSuf, No_wSuf, No_lSuf): Likewise.
	(SHORT_OPCODE_SUFFIX, LONG_OPCODE_SUFFIX): Define.
	* config/tc-i386.c: Rename WORD_PREFIX_OPCODE to
	DATA_PREFIX_OPCODE throughout.

	* config/tc-i386.c (REGISTER_WARNINGS): Define.
	(md_assemble): Rewrite suffix/register operand checking code to be
	more thorough.  Remove Abs8,16,32.  Change occurrences of Mem to
	AnyMem, the better to grep.
	(pi): Remove Abs.
	(i386_operand): Don't set Mem bits in i.types[this_operand] when
	given a memory operand.  Don't set Abs bits either.
	(type_names): Remove Mem*, Abs*.
	* config/tc-i386.h (Mem8, Mem16, Mem32, Abs8, Abs16, Abs32): Don't
	define opcode_modifiers as these cases are handled by Disp8,
	Disp16, Disp32 and suffix checks.
	(COMES_IN_BOTH_DIRECTIONS): Remove.
	(FloatR): Define. It's OK to share the bit with ReverseRegRegmem.

	* config/tc-i386.c (md_assemble): Don't emit operand size prefix
	if IgnoreDataSize modifier given.  Remove ShortformW modifier
	test.  Add test for ShortForm in W base_opcode modification.
	Merge Seg2ShortForm and Seg3ShortForm code.
	* config/tc-i386.h (ShortFormW): Remove.
	(IgnoreDataSize): Define.

* config/tc-i386.c (END_STRING_AND_SAVE): Protect arguments of
	macros and enclose in do while(0).
	(RESTORE_END_STRING): Likewise.
	(md_assemble): Add one to printed operand number so we start
	from 1 not 0.  Add some more gettext invocations.
	(i386_operand): Fix `%%s' -> `%%%s'. Inc printed operand
	number here too.

	* config/tc-i386.h (WAIT_PREFIX, LOCKREP_PREFIX, ADDR_PREFIX,
	DATA_PREFIX, SEG_PREFIX): Define.
	* config/tc-i386.c (struct _i386_insn): Remove wait_prefix field.
	(check_prefix): Remove function.
	(add_prefix): New function.  Add prefix to i.prefix as well as
	doing checks.
	(md_assemble): Changes for add_prefix.	Remove hack for wait
	prefix, instead always output prefixes in fixed order.	Test
	for jcxz/loop when selecting between word & dword operations,
	and add address size prefix rather than operand size prefix.
	Remove operand -> address size hack when emitting jcxz/loop.
	(i386_operand): Remove O_Absent check as it's done in expr.

	from md_assemble.
	(struct _i386_insn): Add wait_prefix field.

	return.  Clarify some comments.

	* config/tc-i386.c (struct _i386_insn): Change seg field to a two
	element array.
	(md_assemble): Parse string instruction operands, looking for
	segment override prefixes.  Check for invalid segment prefixes on
	string instruction.
	(i386_operand): i.seg[] and max mem_operand changes for string
	insns.
	* config/tc-i386.h (EsSeg): Define.

	(iclrKludge, imulKludge): Don't define.
	* config/tc-i386.c (md_assemble): Merge imulKludge and iclrKludge
	code.  Move ReverseRegRegmem fudges into Modrm case.  Reorder
	opcode_modifier checks to look for more common cases first.  Add
	default_seg for IsString case.
