The branch releng/13.1 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=dc543c8786a5345b24bbbf9f8e6725fed2a90b39 commit dc543c8786a5345b24bbbf9f8e6725fed2a90b39 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2022-03-07 13:53:27 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2022-04-18 16:38:39 +0000 libctf: Handle CTFv3 containers In general, the patch adds indirection to minimize the amount of code that needs to know about differences between v2 and v3. Specifically, some new ctf_get_ctt_* functions are added, and new LCTF_* macros are added to use the underlying container's version to do the right thing. CTF containers can have parent/child relationships, wherein a type ID in one container refers to a type in the parent. It is permitted for the parent and child to have different versions.
