| this is the library internal function!! 
| there is a similar function in the statically linked part of the library, but
| that one may not use our library base vector

	.globl	_syscall

_syscall:
	movel	_ixemulbase,a0
	movel	sp@@(4),d0	| get vector number
	addl	#4,d0		| add 4, since we start at offset -30 (first #=1)
	addl	d0,d0
	subl	d0,a0
	addl	d0,d0
	subl	d0,a0

	lea	sp@@(8),sp	| advance to "real" arguments
	jsr	a0@@
	lea	sp@@(-8),sp	| and back, so rts will work ;-)
