[PATCH] D103549: [POC] Put annotation strings into debuginfo.

[David Blaikie via Phabricator via cfe-commits]

dblaikie added a comment.

Generally arbitrary strings are best avoided where possible owing to lack of structure, type safety, semantics, etc. But they might be suitable here since they're opaque to everything from the frontend to the backend.

As for supporting it in DWARF, probably with a custom attribute (`DW_AT_BTF_annotation`? (or "LLVM" instead of "BTF" perhaps, I'm not sure)) with a standard form (DW_FORM_strp/strxN/etc - the usual way we emit strings).
