// RUN: %target-sil-opt -enable-sil-verify-all %s

// This file contains a collection of tests that ensure that the verifier does
// not fail on specific segments of code. The idea is to ensure that changing
// the verifier does not cause these to start asserting. When one adds a new
// check to the verifier, add a test case to make sure normal cases do not
// crash.
