Hal Finkel c37f502d48 Phi speculation improvement for BasicAA ... This is a partial solution to PR14351. It removes some of the special significance of the first incoming phi value in the phi aliasing checking logic in BasicAA. In the context of a loop, the old logic assumes that the first incoming value is the interesting one (meaning that it is the one that comes from outside the loop), but this is often not the case. With this change, we now test first the incoming value that comes from a block other than the parent of the phi being tested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168245 91177308-0d34-0410-b5e6-96231b3b80d8		2012-11-17 02:33:15 +00:00
