The branch main has been updated by fuz: URL: https://cgit.FreeBSD.org/ports/commit/?id=a002d848b52bda537a6d0a90da4616001303f80b commit a002d848b52bda537a6d0a90da4616001303f80b Author: Robert Clausecker <fuz@FreeBSD.org> AuthorDate: 2026-03-18 19:53:07 +0000 Commit: Robert Clausecker <fuz@FreeBSD.org> CommitDate: 2026-03-24 19:12:37 +0000 textproc/krep: fix build on armv7 Add polyfill for the vmaxvq_u8() intrinsic only available on AArch64. This should probably be upstreamed.
