Eliminate more uses of llvm-as and llvm-dis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-08 23:54:48 +00:00			`; RUN: llc < %s -march=x86-64 -mattr=+sse2,-sse41 \| grep {pshufd \$3, %xmm0, %xmm0}`
Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look for the new CONCAT_VECTORS node type instead, as that's what legalize uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@38503 91177308-0d34-0410-b5e6-96231b3b80d8 2007-07-10 18:20:44 +00:00
Favors pshufd over shufps when shuffling elements from one vector. pshufd is faster than shufps. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49244 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-05 00:30:36 +00:00			`define float @foo(<8 x float> %a) nounwind {`
