// Test that when debug info only includes line tables that backtrace is still generated
|
|
// successfully.
|
|
// Original test:
|
|
// <https://github.com/rust-lang/backtrace-rs/tree/6fa4b85b9962c3e1be8c2e5cc605cd078134152b/crates/line-tables-only>.
|
|
// Part of <https://github.com/rust-lang/rust/issues/122899> porting some backtrace tests to rustc.
|
|
// This test diverges from the original test in that it now uses a Rust library auxiliary because
|
|
// rustc now has `-Cdebuginfo=line-tables-only`.
