// In order to prevent temporary files from overwriting each other in parallel
|
|
// compilation, rustc was changed to mix an extra filename with temporary
|
|
// outputs. However, as this is a similar behavior with the codegen flag
|
|
// -C extra-filename, this test checks that the manually passed flag
|
|
// is not overwritten by this feature, and that the output files
|
|
// are named as expected.
|
|
// See https://github.com/rust-lang/rust/pull/15686
