This PR adds ability for the target specifications to specify frame pointer emission type that's not just “always” or “whatever cg decides”. In particular there's a new mode that allows omission of the frame pointer for leaf functions (those that don't call any other functions). We then set this new mode for Aarch64-based Apple targets. Fixes #86196 |
