Richard Sandiford 0548a5487a [SystemZ] Rein back the use of block operations ... The backend tries to use block operations like MVC, NC, OC and XC for simple scalar operations. For correctness reasons, it rejects any case in which the regions might partially overlap. However, for performance reasons, it should also reject cases where the regions might be equal, since the instruction might then not use the fast path. This fixes a performance regression seen in bzip2. We may want to limit the optimisation even more in future, or even remove it entirely, but I'll try with this for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191525 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-27 15:29:20 +00:00
