Method:

Out of the table, we create a wrapper for fplsp.S. It contains:

Single precision:

	movl	sp@(4),sp@-			4
	bsr	_060fplsp+theoffset		4
	fmovs	fp0,sp@				4
	movel	sp@+,d0				4
	rts					2
	(18 bytes)

Double precision:

	movl	sp@(4+0),sp@-			4
	movl	sp@(8+4),sp@-			4
	bsr	_060fplsp+theoffset		4
	fmovd	fp0,sp@				4
	movel	sp@+,d0				4
	movel	sp@+,d1				4
	rts					2
	(26 bytes)

For __SVR4_ABI, the code is much shorter... it reduces to a single jbra.
