Andrew Trick eddf0de054 Use a SparseSet in LiveRegUnits. ... Some clients may add block live ins and may track liveness over a large scope. This guarantees an efficient implementation in all cases with no memory allocation/deallocation, independent of the number of target registers. It could be slightly less convenient but is fine in the expected case. llvm-svn: 192622		2013-10-14 20:45:17 +00:00
