// This test case tests the incremental compilation hash (ICH) implementation
|
|
// for exprs that can panic at runtime (e.g., because of bounds checking). For
|
|
// these expressions an error message containing their source location is
|
|
// generated, so their hash must always depend on their location in the source
|
|
// code, not just when debuginfo is enabled.
|
|
|
|
// 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 -C debug-assertions -O
