Andrew Trick	94db617471	Add TopDownClosureFunctionOrder based on ClosureScopeAnalysis. ... Simple utility for transfersing functions such that parent scopes are always visited before noescape closures. Note that recursion is disallowed. Noescape closures are not reentrant.	2017-06-16 19:08:40 -07:00
Andrew Trick	3bec7d81ac	Add ClosureScopeAnalysis. ... Record noescape closure scopes. This allows passes to process closures and their parent scopes in a controlled order. AccessEnforcementSelection needs this because it needs to process parent scopes before selecting enforcement within noescape closures. Eventually this could be used by the PassManager so that AccessEnforcementSelection can go back to being a function transform.	2017-06-16 19:08:39 -07:00
