Dan Gohman cffddcd726 Don't cache PHI exit values from exhaustive evaluations, because ... an individual exhaustive evaluation reflects only the exit value implied by an individual exit, which may differ from the actual exit value of the loop if there are other exits. This fixes PR4477. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74447 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-29 20:34:13 +00:00
