Matthias Braun d5a7fc40ed VirtRegMap: Improve addMBBLiveIns() using SlotIndex::MBBIndexIterator; NFC ... Now that we have an explicit iterator over the idx2MBBMap in SlotIndices we can use the fact that segments and the idx2MBBMap is sorted by SlotIndex position so can advance both simultaneously instead of starting from the beginning for each segment. This complicates the code for the subregister case somewhat but should be more efficient and has the advantage that we get the final lanemask for each block immediately which will be important for a subsequent change. Removes the now unused SlotIndexes::findMBBLiveIns function. Differential Revision: http://reviews.llvm.org/D12443 llvm-svn: 247170		2015-09-09 18:07:54 +00:00
