Dan Gohman 24bde5bce1 Don't narrow the load and store in a load+twiddle+store sequence unless ... there are clearly no stores between the load and the store. This fixes this miscompile reported as PR7833. This breaks the test/CodeGen/X86/narrow_op-2.ll optimization, which is safe, but awkward to prove safe. Move it to X86's README.txt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112861 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-02 21:18:42 +00:00
