This has proven a healthy exercise, as many cases of incorrect instruction flags were corrected in the process. As part of this, IntrWriteMem was added to several SystemZ instrinsics. Furthermore, a bug was exposed in TwoAddress with this change (as incorrect hasSideEffects flags were removed and instructions could now be sunk), and the test case for that bugfix (r319646) is included here as test/CodeGen/SystemZ/twoaddr-sink.ll. One temporary test regression (one extra copy) which will hopefully go away in upcoming patches for similar cases: test/CodeGen/SystemZ/vec-trunc-to-i1.ll Review: Ulrich Weigand. https://reviews.llvm.org/D40437 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@319756 91177308-0d34-0410-b5e6-96231b3b80d8
