Detailed Description

Translates P4 expressions into Z3. Any variables encountered are declared to a Z3 instance.

Constructor & Destructor Documentation

◆ Z3Translator()

P4::P4Tools::Z3Translator::Z3Translator ( Z3Solver & solver)
explicit

Creates a Z3 translator. Any variables encountered during translation will be declared to the Z3 instance encapsulated within the given solver.

Member Function Documentation

◆ getResult()

z3::expr P4::P4Tools::Z3Translator::getResult ( )
Returns
the result of the translation.

◆ preorder()

bool P4::P4Tools::Z3Translator::preorder ( const IR::Node * node)
overridevirtual

Handles unexpected nodes.

Reimplemented from P4::Inspector.
