virtual bool llvm::CaptureTracker::captured

(

const Use *

U

)

[pure virtual]

captured - Information about the pointer was captured by the user of use U. Return true to stop the traversal or false to continue looking for more capturing instructions.

Referenced by llvm::PointerMayBeCaptured().

bool CaptureTracker::shouldExplore

(

const Use *

U

)

[virtual]

shouldExplore - This is the use of a value derived from the pointer. To prune the search (ie., assume that none of its users could possibly capture) return false. To search it, return true.

U->getUser() is always an Instruction.
