John Mosby b9cfbd94ab Shrink wrapping in PEI: ... - reduces _static_ callee saved register spills and restores similar to Chow's original algorithm. - iterative implementation with simple heuristic limits to mitigate compile time impact. - handles placing spills/restores for multi-entry, multi-exit regions in the Machine CFG without splitting edges. - passes test-suite in LLCBETA mode. Added contains() method to ADT/SparseBitVector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71438 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-11 17:04:19 +00:00
