Documentation

checkPathSatisfiability :: ConfigOption BaseBoolType Source #

pathSatisfiabilityFeature Source #

Arguments

:: forall sym. IsSymInterface sym
=> sym
-> (Maybe ProgramLoc -> Pred sym -> IO BranchResult)	An action for considering the satisfiability of a predicate. In the current state of the symbolic interface, indicate what we can determine about the given predicate.
-> IO (GenericExecutionFeature sym)

checkSatToConsiderBranch :: IsSymInterface sym => sym -> (Pred sym -> IO (SatResult () ())) -> Pred sym -> IO BranchResult Source #

data BranchResult Source #

Result of attempting to branch on a predicate.

Constructors

IndeterminateBranchResult	The both branches of the predicate might be satisfiable (although satisfiablility of either branch is not guaranteed).
NoBranch !Bool	Commit to the branch where the given predicate is equal to the returned boolean. The opposite branch is unsatisfiable (although the given branch is not necessarily satisfiable).
UnsatisfiableContext	The context before considering the given predicate was already unsatisfiable.
