From 2b378139d165f3020082993cad70261aa6e37240 Mon Sep 17 00:00:00 2001 From: Simon Pilgrim Date: Fri, 17 May 2019 14:37:19 +0000 Subject: [PATCH] [X86][AVX] Remove LowerCTTZ's AVX1 custom vector handling. We can now rely on generic expansion to handle this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@361038 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86ISelLowering.cpp | 7 ------- 1 file changed, 7 deletions(-) diff --git a/lib/Target/X86/X86ISelLowering.cpp b/lib/Target/X86/X86ISelLowering.cpp index 6366f2e4f7c..a52d0faa35b 100644 --- a/lib/Target/X86/X86ISelLowering.cpp +++ b/lib/Target/X86/X86ISelLowering.cpp @@ -1190,9 +1190,6 @@ X86TargetLowering::X86TargetLowering(const X86TargetMachine &TM, setOperationAction(ISD::CTPOP, VT, Custom); setOperationAction(ISD::CTLZ, VT, Custom); - // TODO - remove this once 256-bit X86ISD::ANDNP correctly split. - setOperationAction(ISD::CTTZ, VT, HasInt256 ?
