Rafael Espindola babae05237 Second part of pr16069 ... The problem this time seems to be a thinko. We were assuming that in the CFG A | \ | B | / C speculating the basic block B would cause only the phi value for the B->C edge to be speculated. That is not true, the phi's are semantically in the edges, so if the A->B->C path is taken, any code needed for A->C is not executed and we have to consider it too when deciding to speculate B. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183226 91177308-0d34-0410-b5e6-96231b3b80d8		2013-06-04 14:11:59 +00:00
