// This test revolves around the rustc flag -Z profile, which should
|
|
// generate a .gcno file (initial profiling information) as well
|
|
// as a .gcda file (branch counters). The path where these are emitted
|
|
// should also be configurable with -Z profile-emit. This test checks
|
|
// that the files are produced, and then that the latter flag is respected.

// See https://github.com/rust-lang/rust/pull/42433
