// This file defines the function verifier interface, that can be used for some
// sanity checking of input to the system, and for checking that transformations
// haven't done something bad.
//
// Note that this does not provide full 'java style' security and verifications,
// instead it just tries to ensure that code is well formed.
//
// To see what specifically is checked, look at the top of Verifier.cpp
