The branch stable/15 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=1c7e291da65a1dd30edc59e6ecc4b5bdc5e49af2 commit 1c7e291da65a1dd30edc59e6ecc4b5bdc5e49af2 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2026-02-09 16:26:29 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2026-04-24 15:32:43 +0000 libmd aarch64: Use ands instead of bics to round down the length GNU as does not accept bics with two register operands but instead requires three register operands. However, clang assembles the bics instruction to ands anyway, so just use ands directly.
