[LLVMdev] Execution domain for VEXTRACTF128/VINSERTF128
Hi,
I noticed, that execution domain is set to SSEPackedSingle for these instructions.
Looks like a bug.
let neverHasSideEffects = 1, ExeDomain = SSEPackedSingle in {
def VEXTRACTF128rr : AVXAIi8<0x19, MRMDestReg, (outs VR128:$dst),

[LLVMdev] Execution domain for VEXTRACTF128/VINSERTF128
I think that it should not belong to any domain.
And I see a problem with this table. If you run in AVX mode and call lookup with VEXTRACTF128rr you fail with assertion.

...ey should have? They are floating point, but not
technically double or single. The domain fix pass will treat them as either
anyway as I've put them in the table for both single and double.
