From c5071466d42bbb13803203d5b70ca0eef26189f4 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Wed, 19 Dec 2012 15:49:14 +0000 Subject: [PATCH] PowerPC: Expand VSELECT nodes. There's probably a better expansion for those nodes than the default for altivec, but this is better than crashing. VSELECTs occur in loop vectorizer output. llvm-svn: 170551 --- llvm/lib/Target/PowerPC/PPCISelLowering.cpp | 1 + llvm/test/CodeGen/PowerPC/vec_select.ll | 7 +++++++ 2 files changed, 8 insertions(+) create mode 100644 llvm/test/CodeGen/PowerPC/vec_select.ll diff --git a/llvm/lib/Target/PowerPC/PPCISelLowering.cpp b/llvm/lib/Target/PowerPC/PPCISelLowering.cpp index 2569710..9cc4e96 100644 --- a/llvm/lib/Target/PowerPC/PPCISelLowering.cpp +++ b/llvm/lib/Target/PowerPC/PPCISelLowering.cpp @@ -376,6 +376,7 @@ PPCTargetLowering::PPCTargetLowering(PPCTargetMachine &TM) setOperationAction(ISD::CTLZ_ZERO_UNDEF, VT, Expand); setOperationAction(ISD::CTTZ, VT, Expand); setOperationAction(ISD::CTTZ_ZERO_UNDEF, VT, Expand); + setOperationAction(ISD::VSELECT, VT, Expand); setOperationAction(ISD::SIGN_EXTEND_INREG, VT, Expand); for (unsigned j = (unsigned)MVT::FIRST_VECTOR_VALUETYPE; diff --git a/llvm/test/CodeGen/PowerPC/vec_select.ll b/llvm/test/CodeGen/PowerPC/vec_select.ll new file mode 100644 index 0000000..4ad0acc --- /dev/null +++ b/llvm/test/CodeGen/PowerPC/vec_select.ll @@ -0,0 +1,7 @@ +; RUN: llc < %s -mtriple=powerpc64-linux-gnu -mattr=+altivec | FileCheck %s + +; CHECK: vsel_float +define <4 x float> @vsel_float(<4 x float> %v1, <4 x float> %v2) { + %vsel = select <4 x i1> , <4 x float> %v1, <4 x float> %v2 + ret <4 x float> %vsel +} -- 2.7.4
