[PATCH] D144999: [RFC][MC][MachO]Only emits compact-unwind format for "canonical" personality symbols. For the rest, use DWARFs.

[Jez Ng via Phabricator via llvm-commits]

int3 added a comment.

Why not let the end user decide whether to enable DWARF unwind by passing `-femit-dwarf-unwind`?

> As a result, any system that needs custom-personality will run into a problem.

This isn't true; it will only run into a problem if it is using all 3 of the canonical personalities, which isn't always the case. E.g. we definitely link Rust programs successfully even without this
