From b706d29f9c5ed3ed9acc82f7ab46205ba56b92dc Mon Sep 17 00:00:00 2001 From: Nate Begeman Date: Fri, 24 Apr 2009 03:42:54 +0000 Subject: PR2957 ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69952 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/vec_shuffle-31.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test/CodeGen/X86/vec_shuffle-31.ll') diff --git a/test/CodeGen/X86/vec_shuffle-31.ll b/test/CodeGen/X86/vec_shuffle-31.ll index 0a9dc1fa7b..efcd0300e3 100644 --- a/test/CodeGen/X86/vec_shuffle-31.ll +++ b/test/CodeGen/X86/vec_shuffle-31.ll @@ -1,6 +1,6 @@ ; RUN: llvm-as < %s | llc -march=x86 -mcpu=yonah -o %t -f ; RUN: grep pextrw %t | count 1 -; RUN: grep punpcklqdq %t | count 1 +; RUN: grep movlhps %t | count 1 ; RUN: grep pshufhw %t | count 1 ; RUN: grep pinsrw %t | count 1 ; RUN: llvm-as < %s | llc -march=x86 -mcpu=core2 -o %t -f -- cgit v1.2.3
