Chris Lattner 78c552ef30 implement a transformation in jump threading that is currently ... done by condprop, but do it in a much more general form. The basic idea is that we can do a limited form of tail duplication in the case when we have a branch on a phi. Moving the branch up in to the predecessor block makes instruction selection much easier and encourages chained jump threadings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83759 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-11 07:24:57 +00:00
