As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias (movzx/movsx) because they give more information. Revert that part of the patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129498 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-14 01:46:37 +00:00			`; RUN: llc < %s -mtriple=x86_64-apple-darwin \| grep movzbl`
Fix a (u)comiss intrinsic lowering bug. It was using anyext which can return junk in higher bits. Patch by Nate Begeman. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54903 91177308-0d34-0410-b5e6-96231b3b80d8 2008-08-17 19:22:34 +00:00
