Other Info
==========
Based on this
https://github.com/google/highway/blob/master/run_tests.sh

I am going to try to force building for the ppc8 baseline instead of ppc9

[Launchpad Janitor (janitor)]

This bug was fixed in the package highway - 1.0.7-2ubuntu1

---------------
highway (1.0.7-2ubuntu1) mantic; urgency=medium

  * Force building for a ppc8 baseline to avoid build failure on ppc64el
    (LP: #2033690)

highway (1.0.7-2) unstable; urgency=medium

  * d/patches: Fix make test on i386
  * d/rules: Prefer g++-12 for now. See #1050933
