I am struggling with the plan9 assembler syntax
and its error messages, Anyone spot my silly?

This is my code

	TEXT	count_leading_zeros+0(SB),0,$0
	MOVL	n+0(FP),BX
	BSRL	BX,AX
	MOVL	$31,BX
	SUB		BX,AX
	RET		,

which gives

	larch% 8a plan9-386.c
	plan9-386.c:7 syntax error, last name: BX
	line:  LNAME.: $$5 line
	inst:  LNAME.= expr
	saw LLREG

Thanks for any help.

-Steve

thanks so erik and cinap,

 it's so hard to see what IS there rather than what you know should be there.
