Recent discussion at compiler steering meeting pointed out that #98350 added an unstable -Z flag to opt into DWARF5.

This issue is meant to track the path from that unstable flag to something functionality that would be provided on stable Rust.

Ideally this design proposal would include some method of exposing it to cargo build scripts, so crates like cc would be able to use the right version of DWARF (see rust-lang/cc-rs#694, for example, where we hardcode decisions compatible with rustc)

Is there a unstable way to opt-in DWARF5 for Rust now?
Tried -Zdwarf-version=5 in macOS, but seems failed.
