 ChromiumCheckModel ()=default
 
bool transfer (const CFGElement &Element, Environment &Env) override
 Return value indicates whether the model processed the Element.

 Return value indicates whether the model processed the Element.

virtual ~ValueModel ()=default
 
virtual ComparisonResult compare (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2)
 Returns: Same: Val1 is equivalent to Val2, according to the model.
 
virtual void join (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2, Value &JoinedVal, Environment &JoinedEnv)
 Modifies JoinedVal to approximate both Val1 and Val2.
 
virtual std::optional< WidenResultwiden (QualType Type, Value &Prev, const Environment &PrevEnv, Value &Current, Environment &CurrentEnv)
 This function may widen the current value – replace it with an approximation that can reach a fixed point more quickly than iterated application of the transfer function alone.
 

Detailed Description

Models the behavior of Chromium's CHECK, DCHECK, etc.

macros, so that code after a call to *CHECK can rely on the condition being true.
