isAddressTraceable()

bool GlobalVsStackAA::isAddressTraceable ( DataDependenceGraph &  ddg, const ProgramOperation &  pop  )

virtual

Checks whether the analyzer knows anything about the address.

ie. if it can return true or false to some query concerning this address.

Returns

true if analyzer can know something about the address.
