| | | | | | | | a problem in LoopStrengthReduction, where it would split critical edges then confused itself with outdated loop information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22776 91177308-0d34-0410-b5e6-96231b3b80d8
* Change break critical edges to not remove, then insert, PHI node entries.Chris Lattner2005-08-121-2/+2
| | | | | | | | Instead, just update the BB in-place. This is both faster, and it prevents split-critical-edges from shuffling the PHI argument list unneccesarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22765 91177308-0d34-0410-b5e6-96231b3b80d8
