// 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.

// must-compile-successfully
// revisions: cfail1 cfail2 cfail3
