Dan Gohman 3bdd8de280 Enhance CodePlacementOpt's unconditional intra-loop branch elimination logic ... to be more general and understand more varieties of loops. Teach CodePlacementOpt to reorganize the basic blocks of a loop so that they are contiguous. This also includes a fair amount of logic for preserving fall-through edges while doing so. This fixes a BranchFolding-ism where blocks which can't be made to use a fall-through edge and don't conveniently fit anywhere nearby get tossed out to the end of the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84295 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-17 00:32:43 +00:00
