Referenced by getLoans(), and transfer().

join()

Lattice clang::lifetimes::internal::LoanPropagationAnalysis::join ( Lattice A, Lattice B )

inline

Merges two lattices by taking the union of loans for each origin.

Definition at line 1089 of file LifetimeSafety.cpp.

References clang::lifetimes::internal::utils::join(), and clang::lifetimes::internal::LoanPropagationLattice::Origins.

transfer() [1/2]

Lattice clang::lifetimes::internal::LoanPropagationAnalysis::transfer ( Lattice In, const IssueFact & F )

inline

A new loan is issued to the origin. Old loans are erased.

Definition at line 1099 of file LifetimeSafety.cpp.

References clang::lifetimes::internal::IssueFact::getLoanID(), and clang::lifetimes::internal::IssueFact::getOriginID().

transfer() [2/2]

Lattice clang::lifetimes::internal::LoanPropagationAnalysis::transfer ( Lattice In, const OriginFlowFact & F )

inline

A flow from source to destination.

If KillDest is true, this replaces the destination's loans with the source's. Otherwise, the source's loans are merged into the destination's.

Definition at line 1110 of file LifetimeSafety.cpp.
