// 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.
