llvm/test/CodeGen/X86: FileCheck-ize two tests in r171083. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171084 91177308-0d34-0410-b5e6-96231b3b80d8 2012-12-26 03:19:30 +00:00			`; RUN: llc < %s -march=x86 -mcpu=penryn \| FileCheck %s`
Bug: rcpps can only folds a load if the address is 16-byte aligned. Fixed many 'ps' load folding patterns in X86InstrSSE.td which are missing the proper alignment checks. Also fixed some 80 col. violations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51462 91177308-0d34-0410-b5e6-96231b3b80d8 2008-05-23 00:37:07 +00:00
