Dan Gohman 6824bfc554 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. llvm-svn: 112861		2010-09-02 21:18:42 +00:00
