The branch main has been updated by rlibby: URL: https://cgit.FreeBSD.org/src/commit/?id=bac7bd5038e09d12dfdbf79a87b25443e02d0ba9 commit bac7bd5038e09d12dfdbf79a87b25443e02d0ba9 Author: Ryan Libby <rlibby@FreeBSD.org> AuthorDate: 2026-05-11 05:39:27 +0000 Commit: Ryan Libby <rlibby@FreeBSD.org> CommitDate: 2026-05-11 05:39:27 +0000 linux: address executable stack warnings Mark assembly files as not requiring executable stacks. This still leaves linux32_vdso.so without a .note.GNU-stack section in the gcc build for now.
