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