* Rename the Region::block_iterator to Region::block_node_iterator, andChandler Carruth2012-05-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | add a new Region::block_iterator which actually iterates over the basic blocks of the region. The old iterator, now call 'block_node_iterator' iterates over RegionNodes which contain a single basic block. This works well with the GraphTraits-based iterator design, however most users actually want an iterator over the BasicBlocks inside these RegionNodes. Now the 'block_iterator' is a wrapper which exposes exactly this interface. Internally it uses the block_node_iterator to walk all nodes which are single basic blocks, but transparently unwraps the basic block to make user code simpler. While this patch is a bit of a wash, most of the updates are to internal users, not external users of the RegionInfo. I have an accompanying patch to Polly that is a strict simplification of every user of this interface, and I'm working on a pass that also wants the same simplified interface. This patch alone should have no functional impact. llvm-svn: 156202

* Add RegionPass support.Tobias Grosser2010-10-201-0/+276
A RegionPass is executed like a LoopPass but on the regions detected by the RegionInfo pass instead of the loops detected by the LoopInfo pass. llvm-svn: 116905
