Forward-declares and imports various common LLVM datatypes that clang wants to use unqualified.

bool isUnderconstrained() const

Return true if the constrained is underconstrained and we do not know if the constraint is true of va...

ConditionTruthVal()=default

Construct a ConstraintVal indicating the constraint is underconstrained.

bool isConstrainedFalse() const

Return true if the constraint is perfectly constrained to 'false'.

bool isConstrained() const

Return true if the constrained is perfectly constrained.

ConditionTruthVal(bool constraint)

Construct a ConditionTruthVal indicating the constraint is constrained to either true or false,...

bool isConstrainedTrue() const

Return true if the constraint is perfectly constrained to 'true'.

A helper class to simulate the call stack of nested assume calls.

virtual const llvm::APSInt * getSymMaxVal(ProgramStateRef state, SymbolRef sym) const

Attempt to return the minimal possible value for a given symbol.

ProgramStateRef assumeInclusiveRange(ProgramStateRef State, NonLoc Value, const llvm::APSInt &From, const llvm::APSInt &To, bool InBound)

virtual const llvm::APSInt * getSymVal(ProgramStateRef state, SymbolRef sym) const

If a symbol is perfectly constrained to a constant, attempt to return the concrete value.

virtual void printValue(raw_ostream &Out, ProgramStateRef State, SymbolRef Sym)

virtual bool canReasonAbout(SVal X) const =0

canReasonAbout - Not all ConstraintManagers can accurately reason about all SVal values.

ProgramState - This class encapsulates:

SVal - This represents a symbolic expression, which can be either an L-value or an R-value.

A class responsible for cleaning up unused symbols.
