cgen opcodes/asm patch

[Frank Ch. Eigler]

Hi -

I'm about to commit a small patch to opcodes/cgen-asm.in, intended to
improve the error message for an instruction that lacks required operands.

2000-12-28  Frank Ch. Eigler  <fche@redhat.com>

	* cgen-asm.in (parse_insn_normal): Print better error message for
	instructions with missing operands.
