Chris Lattner c581acbbba Fix a pretty serious misfeature of the inliner: if it inlines a function ... with multiple return values it inserts a PHI to merge them all together. However, if the return values are all the same, it ends up with a pointless PHI and this pointless PHI happens to really block SRoA from happening in at least a silly C++ example written by Doug, but probably others. This fixes rdar://7339069. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85206 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-27 05:39:41 +00:00
