The transferValues() function can now handle both singly and multiply defined values, as long as the resulting live range is known. Only rematerialized values have their live range recomputed by extendRange(). The updateSSA() function can now insert PHI values in bulk across multiple values in multiple target registers in one pass. The list of blocks received from transferValues() is in layout order which seems to work well for the iterative algorithm. Blocks from extendRange() are still in reverse BFS order, but this function is used so rarely now that it doesn't matter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129580 91177308-0d34-0410-b5e6-96231b3b80d8
