// When we generate the import library for a dylib or bin crate, we should generate it
|
|
// for the symbols both for the current crate and all upstream crates. This allows for
|
|
// using the link kind `raw-dylib` inside inline functions successfully. This test checks
|
|
// that the import symbols in the object files match this convention, and that execution
|
|
// of the binary results in all function names exported successfully.
|
|
// See https://github.com/rust-lang/rust/pull/102988
