Constructor & Destructor Documentation

SymbolicExecution()

hal::SMT::SymbolicExecution::SymbolicExecution ( const std::vector< BooleanFunction > &  variables = {} )

explicit

Creates a symbolic execution engine and initializes the variables.

Parameters

[in]

variables

- The (optional) list of variables.

Member Function Documentation

evaluate() [1/2]

Result< BooleanFunction > hal::SMT::SymbolicExecution::evaluate

(

const BooleanFunction &

function

)

const

Evaluates a Boolean function within the symbolic state of the symbolic execution.

Parameters

[in]

function

- The Boolean function to evaluate.

Returns

Ok() and the evaluated Boolean function on success, Err() otherwise.

evaluate() [2/2]

Result< std::monostate > hal::SMT::SymbolicExecution::evaluate

(

const Constraint &

constraint

)

Evaluates an equality constraint and applies it to the symbolic state of the symbolic execution.

Parameters

[in]

constraint

- The equality constraint to evaluate.
