--- Comment #5 from Jan Beich <jbeich@FreeBSD.org> ---
Likely regressed
https://gitlab.freedesktop.org/pixman/pixman/-/commit/92ee80d42356
FreeBSD uses HWCAP_* instead of COMPAT_HWCAP_* and <machine/elf.h> (already
included via <sys/auxv.h>) instead of <asm/hwcap.h>.
However, HWCAP_ISA_V (vector extension) is not implemented, and according to
https://wiki.freebsd.org/riscv#Future.2FLarger_Projects none is working on it
yet.
