// This test case tests the incremental compilation hash (ICH) implementation
// for struct constructor expressions.

// 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 cfail4 cfail5 cfail6
// compile-flags: -Z query-dep-graph -O
// [cfail1]compile-flags: -Zincremental-ignore-spans
// [cfail2]compile-flags: -Zincremental-ignore-spans
// [cfail3]compile-flags: -Zincremental-ignore-spans
