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 Tidy up. 2010-09-02T21:02:27Z Devang Patel dpatel@apple.com 2010-09-02T21:02:27Z urn:sha1:8e741ed2fa16f46ab586bf3a54526cd9c2338c5b git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112858 91177308-0d34-0410-b5e6-96231b3b80d8 Reapply r112623.
