Jeffrey Yasskin 493a3d015c LiveVariables::VarInfo contains an AliveBlocks BitVector, which has as many ... entries as there are basic blocks in the function. LiveVariables::getVarInfo creates a VarInfo struct for every register in the function, leading to quadratic space use. This patch changes the BitVector to a SparseBitVector, which doesn't help the worst-case memory use but does reduce the actual use in very long functions with short-lived variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72426 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-26 18:27:15 +00:00
