// When rustc received 4 codegen-units, an output path and an emit flag all simultaneously,
|
|
// this could cause an annoying recompilation issue, uselessly lengthening the build process.
|
|
// A fix was delivered, which resets codegen-units to 1 when necessary,
|
|
// but as it directly affected the way codegen-units are manipulated,
|
|
// this test was created to check that this fix did not cause compilation failures.
|
|
// See https://github.com/rust-lang/rust/issues/30063
