* Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.hChris Lattner2008-04-211-0/+101
| | | | | | | | | | as a global helper function. At the same type, switch it from taking a vector of predecessors to an arbitrary sequential input. This allows us to switch LoopSimplify to use a SmallVector for various temporary vectors that it passed into SplitBlockPredecessors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50020 91177308-0d34-0410-b5e6-96231b3b80d8

* Two things. Preserve the unwind_to when splitting a BB.Nick Lewycky2008-03-091-0/+1
| | | | | | | | Add the ability to remove just one instance of a BB from a phi node. This fixes the compile error in the tree now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48085 91177308-0d34-0410-b5e6-96231b3b80d8
