From 56a41d4b3a0c44f83f1763c39120eaea45bb8996 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Wed, 29 Nov 2017 23:08:25 +0000 Subject: [X86] Remove some questionable looking code that seems to be looking through a VZEXT to create a larger VSEXT. If the input the vzext was signed this would do the wrong thing. Not sure how to test this. llvm-svn: 319382 --- llvm/lib/Target/X86/X86ISelLowering.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'llvm/lib') diff --git a/llvm/lib/Target/X86/X86ISelLowering.cpp b/llvm/lib/Target/X86/X86ISelLowering.cpp index 051a7624e0f..36c284b0bc1 100644 --- a/llvm/lib/Target/X86/X86ISelLowering.cpp +++ b/llvm/lib/Target/X86/X86ISelLowering.cpp @@ -18285,7 +18285,7 @@ static SDValue LowerSIGN_EXTEND_AVX512(SDValue Op, if (VT.is512BitVector() && InVTElt != MVT::i1 && (NumElts == 8 || NumElts == 16 || Subtarget.hasBWI())) { - if (In.getOpcode() == X86ISD::VSEXT || In.getOpcode() == X86ISD::VZEXT) + if (In.getOpcode() == X86ISD::VSEXT) return getExtendInVec(In.getOpcode(), dl, VT, In.getOperand(0), DAG); return getExtendInVec(X86ISD::VSEXT, dl, VT, In, DAG); } -- cgit v1.2.3
