// Between revisions 1 and 2, we are changing the debuginfo-level, which should
// invalidate the cache. Between revisions 2 and 3, we are adding `--verbose`
// which should have no effect on the cache:
//[rpass1] compile-flags: -C debuginfo=0
//[rpass2] compile-flags: -C debuginfo=2
//[rpass3] compile-flags: -C debuginfo=2 --verbose
