'_knot_mask8'

     Type:  defect   |     Status:  assigned
 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.8.1
 Keywords:           |       Port:  highway
---------------------+----------------------
 There are several occurrences, but it's the same identifier that's missing
 in all cases:

 {{{
 .../work/highway-1.0.7/hwy/ops/x86_256-inl.h:5781:33: error: use of
 undeclared identifier '_knot_mask8'
       _mm256_maskz_cvttpd_epu32(_knot_mask8(MaskFromVec(v).raw), v.raw)};
                                 ^
 }}}

 This is occurring both on the 10.14 buildbot, as well as locally.
