0
	* final.c (final): If a label is reached only from a single jump,
	call NOTICE_UPDATE_CC on the jump and its predecessor before
	emitting the insn after the label.
	* i386.h: Add AMD K6 support.
	Change TARGET_* macros to use table lookup.
	(INITIALIZE_TRAMPOLINE): Improve trampoline code.
	(ADJUST_COST): Change definition to call function in i386.c.
	(ISSUE_RATE): Define as 2 for anything newer than an 80486.
	* i386.c: Add AMD K6 support.
	Add constants for feature tests used by TARGET_* macros.
	(split_di): If before reload, call gen_lowpart and gen_highpart.
	(x86_adjust_cost): New function.
	(put_jump_code): New function.
	(print_operand): New codes 'D' and 'd'.
	* i386.md: New insn types.  New insn attribute "memory".
	Redefine scheduling parameters to use new types and add AMD K6
	support.  Explicitly set type of most insns.
	(move insns): K6 prefers movl $0,reg to xorl reg,reg.  Pentium
	Pro and K6 prefer movl $1,reg to incl reg.
	(adddi3, subdi3): Set cc_status.
	(DImode shift patterns): Change label counters from HOST_WIDE_INT
	to int; x86 can't have more than 2^31 DImode shifts per	file.
	(setcc): Combine all setcc patterns.  Allow writing memory.
	Combine all jump patterns using match_operator.
	(*bzero): Name pattern.  Emit mutliple stos instructions when that
	is faster than rep stos.
	(xordi3, anddi3, iordi3): Simplify DImode logical patterns and
	add define_split.
	* ch/Make-lang.in: Comment ^L characters.  Sun make doesn't like them.
