// Between revisions 1 and 2, we are changing the debuginfo-level, which should
// invalidate the cache. Between revisions 2 and 3, we are adding `--diagnostic-width`
// which should have no effect on the cache. Between revisions, we are adding
// `--remap-path-prefix` which should invalidate the cache:
//@[rpass1] compile-flags: -C debuginfo=0

// Regression test for https://github.com/rust-lang/rust/issues/156182.
// `-Zunstable-options` enables internal lints, so the lint store changes without
// changing the incremental command-line hash.
