following values:
.b
.lt
	-1	if quadword < 0
	0	if quadword = 0
	1	if quadword > 0
.el
.b
For example:
.b
.lt
	tstq	target
.el
.b
will produce the following code:
.b
.lt
		tstl	4+target
		blss	30001$
		bgtr	30002$
		tstl	target
		bnequ	30002$
		clrl	r0
		brb	30003$
	30001$:	movl	#-1,r0
		brb	30003$
	30002$:	movl	#1,r0
	30003$:
