+// This test case tests the incremental compilation hash (ICH) implementation
+// for consts.
+
+// 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.
+
+// build-pass (FIXME(62277): could be check-pass?)
+// revisions: cfail1 cfail2 cfail3
+// compile-flags: -Z query-dep-graph -O
