Description
Decouples FixpointInfo from the lattice-level methods of ProgramState.
top() and bottom() now preserve the current fixpoint information instead of resetting it.
isTop() and isBottom() no longer include FixpointInfo in their checks.
Fixed bugs
None.
Implemented features
#362
Further content
clearInfo() and clearExecutionInfo() methods are added respectively to the ProgramState and AnalysisState to explicitly discard all fixpoint information when needed. The semantic sanity checks are updated to reflect that getExecutionInformation() of AnalysisState (which is implemented by delegating ProgramState.getFixpointInformation()) is decoupled from the lattice structure.
