The branch stable/12 has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=f4fed768bba45a406f73ed1491d7e52fd1a8711d commit f4fed768bba45a406f73ed1491d7e52fd1a8711d Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2021-08-29 13:53:40 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2021-09-02 23:30:30 +0000 Don't error out on unused but set variables with clang 13 Clang 13.0.0 now has a -Wunused-but-set-variable warning similar to the one gcc has had for quite a while. Since this triggers *very* often for our kernel builds, don't make it a hard error, but leave the warning visible so is some incentive to fix the instances.
