Check Pred on all accesses to the memory kinds specified by MLK.

This method will evaluate Pred on all accesses (access instruction + underlying accessed memory pointer) and it will return true if Pred holds every time.

◆ classof()

This function should return true if the type of the AA is AAMemoryLocation.

◆ inverseLocation()

static MemoryLocationsKind llvm::AAMemoryLocation::inverseLocation ( MemoryLocationsKind  Loc,

Return the inverse of location Loc, thus for NO_XXX the return describes ONLY_XXX.

The flags AndLocalMem and AndConstMem determine if local (=stack) and constant memory are allowed as well. Most of the time we do want them to be included, e.g., argmemonly allows accesses via argument pointers or local or constant memory accesses.
