// Test that #[inline] functions still get inlined across compilation unit
|
|
// boundaries. Compilation should produce three IR files, but only the two
|
|
// compilation units that have a usage of the #[inline] function should
|
|
// contain a definition. Also, the non-#[inline] function should be defined
|
|
// in only one compilation unit.
|
|
// See https://github.com/rust-lang/rust/pull/16367
