// This test case tests the incremental compilation hash (ICH) implementation

// The general pattern followed here is: Change one thing between rev1 and rev2
|
|
// and make sure that the hash has changed, then change nothing between rev2 and
|
|
// rev3 and make sure that the hash has not changed.
