How to disable other lmul except lmul=1

[iknowzxc]

I modified code in insn_util.go to this

var allLMULs = []LMUL{1} var wideningMULs = []LMUL{1} var validLMULs = map[LMUL]struct{}{ allLMULs[0]: {}, }

But compilation has error 2025/06/26 08:03:42 unreachable 2025/06/26 08:03:42 unreachable make: *** [Makefile:121: generate-stage1] Error 1 make: *** Waiting for unfinished jobs....

What should I do

What is the use case? This does not make sense to me.

I want all generated cases to use LMUL = 1 only, and not allow values like 1/2, 1/4, 2, 4, or any others.

Hmm okay, maybe try this?

var allLMULs = []LMUL{1}
var wideningMULs = []LMUL{1}
var validLMULs = map[LMUL]struct{}{
	LMUL(1) / 8: {},
	LMUL(1) / 4: {},
	LMUL(1) / 2: {},
	LMUL(1): {},
	LMUL(2): {},
	LMUL(4): {},
	LMUL(8): {}
}

But you do realize there is EMUL, which is not always 1 even if you restrict all the LMUL to 1, right?
