The branch main has been updated by brooks: URL: https://cgit.FreeBSD.org/src/commit/?id=80ffc7398b8302b2d54d783d8349e54d877a4250 commit 80ffc7398b8302b2d54d783d8349e54d877a4250 Author: Brooks Davis <brooks@FreeBSD.org> AuthorDate: 2024-04-22 19:13:35 +0000 Commit: Brooks Davis <brooks@FreeBSD.org> CommitDate: 2024-04-22 20:28:51 +0000 libsys/arm: make vfork less of an outlier Following the pattern of other architectures, make __sys_vfork the main symbol and _vfork and vfork weak aliases. This avoids the need to special case vfork in the generated list of symbols.
