// 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
