Try SSE2? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68423 91177308-0d34-0410-b5e6-96231b3b80d8 2009-04-04 10:24:24 +00:00			`; RUN: llvm-as < %s \| llc -march=x86 -mattr=+sse2 -o %t -f`
Fix a problem with DAGCombine where we were building an illegal build vector shuffle mask. Forced the mask to be built using i32. Note: this will be irrelevant once vector_shuffle no longer takes a build vector for the shuffle mask. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67076 91177308-0d34-0410-b5e6-96231b3b80d8 2009-03-17 06:33:10 +00:00			`; RUN: grep unpcklpd %t \| count 1`
