.b 3
This macro performs quadword comparison.
.b
This macro will produce inline code to perform the quadword comparion.
After the comparison is performed, r0 will contain the following values:
.b
.lt
	-1	if source < destination
	0	if source = destination
	1	if source > destination
.el
.b
For example:
.b
.lt
	cmpq	source,target
.el
.b
will generate the following code:
.b
.lt
		movq	source,r2
		subl	target,r2
		sbcw	4+target,r3
		tstl	r3
		blss	30001$
		bgtr	30002$
		tstl	r2
		bnequ	30002$
		clrl	r0
		brb	30003$
	30001$:	movl	#-1,r0
		brb	30003$
	30002$:	movl	#1,r0
	30003$:
