[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
What domain do you think they 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.>From X86InstrInfo.cpp{ X86::VEXTRACTF128mr, X86::VEXTRACTF128mr, X86::VEXTRACTI128mr }, { X86::VEXTRACTF128rr, X86::VEXTRACTF128rr, X86::VEXTRACTI128rr }, { X86::VINSERTF128rm, X86::VINSERTF128rm, X86::VINSERTI128rm }, { X86::VINSERTF128rr, X86::VINSERTF128rr, X86::VINSERTI128rr }, { X86::VPERM2F128rm, X86::VPERM2F128rm, X86::VPERM2I128rm }, { X86::VPERM2F128rr, X86::VPERM2F128rr, X86::VPERM2I128rr } On Wed, Jan 4, 2012 at 4:32 AM, Demikhovsky, Elena < elena.demikhovsky at intel.com> wrote:> 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), > > - Elena > > > --------------------------------------------------------------------- > Intel Israel (74) Limited > > This e-mail and any attachments may contain confidential material for > the sole use of the intended recipient(s).

[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. - Elena From: Craig Topper [mailto:craig.topper at gmail.com] Sent: Wednesday, January 04, 2012 19:32 To: Demikhovsky, Elena Cc: llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] Execution domain for VEXTRACTF128/VINSERTF128 What domain do you think they should have?
