Dan Gohman 882d87d168 Check to see if a two-entry PHI block can be simplified ... before trying to merge the block into its predecessors. This allows two-entry-phi-return.ll to be simplified into a single basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48252 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-11 21:53:06 +00:00
