Bill Wendling 7e8840c4d9 Add SplitLandingPadPredecessors(). ... SplitLandingPadPredecessors is similar to SplitBlockPredecessors in that it splits the current block and attaches a set of predecessors to the new basic block. However, it differs from SplitBlockPredecessors in that it's specifically designed to handle landing pad blocks. Two new basic blocks are created: one that is has the vector of predecessors as its predecessors and one that has the remaining predecessors as its predecessors. Those two new blocks then receive a cloned copy of the landingpad instruction from the original block. The landingpad instructions are joined in a PHI, etc. Like SplitBlockPredecessors, it updates the LLVM IR, AliasAnalysis, DominatorTree, DominanceFrontier, LoopInfo, and LCCSA analyses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138014 91177308-0d34-0410-b5e6-96231b3b80d8		2011-08-19 00:05:40 +00:00
