Chandler Carruth 4a85cc982a Add loop aligning to MachineBlockPlacement based on review discussion so it's a bit more plausible to use this instead of CodePlacementOpt. The code for this was shamelessly stolen from CodePlacementOpt, and then trimmed down a bit. There doesn't seem to be much utility in returning true/false from this pass as we may or may not have rewritten all of the blocks. Also, the statistic of counting how many loops were aligned doesn't seem terribly important so I removed it. If folks would like it to be included, I'm happy to add it back. This was probably the most egregious of the missing features, and now I'm going to start gathering some performance numbers and looking at specific loop structures that have different layout between the two. Test is updated to include both basic loop alignment and nested loop alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142645 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-21 08:57:37 +00:00
