 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.5.4
 Keywords:              |       Port:  OpenBLAS
------------------------+----------------------
 Tried to install OpenBLAS port on my iMac Pro under MacOS 10.13 with

 {{{
 port install OpenBLAS +gcc7 +lapack
 }}}

 After a while, it fails with an error about a missing instruction:

 {{{
 :info:build
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_math_OpenBLAS/OpenBLAS/work/.tmp/ccY92TYq.s:70:2:
 error: instruction requires: AVX-512 DQ ISA
 :info:build         vxorps  %zmm0, %zmm0, %zmm0
 :info:build         ^
 }}}

 I also tried with the default gcc8, and there were more missing
 instructions.

 Full log is attached.
