Hal Finkel 8db585afaa Move the CapturesBefore tracker from AA into CaptureTracking ... There were two generally-useful CaptureTracker classes defined in LLVM: the simple tracker defined in CaptureTracking (and made available via the PointerMayBeCaptured utility function), and the CapturesBefore tracker available only inside of AA. This change moves the CapturesBefore tracker into CaptureTracking, generalizes it slightly (by adding a ReturnCaptures parameter), and makes it generally available via a PointerMayBeCapturedBefore utility function. This logic will be needed, for example, to perform noalias function parameter attribute inference. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213519 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-21 13:15:48 +00:00
