# Ideally we'd build and run all Highway unit tests across all platforms.
# Unfortunately, the test suite is an absolute beast to compile and ends
# up timing out on EPEL 10 after 5 hours... There is also the case of a
# small set of tests reliably failing on Fedora Copr's Aarch64 SVE/SVE256
# build nodes:
#
#  - HwyBlockwiseShiftTestGroup/HwyBlockwiseShiftTest.TestAllShiftRightLanes/SVE
#  - UnrollerTestGroup/UnrollerTest.TestAllConvert/SVE_256
#
# The first failure appears to be a possible GCC miscompilation, see
# https://github.com/google/highway/issues/1938. The second failure is from
# a component we don't use (we have our own unrolling primitives).
#
# The unfortunate consequence is that we disable building and running of
# the unit test suite on EPEL 10. We have to trust that Google's build farm
# has caught any particularly funky business.
# TODO: reenable tests on EPEL 10 once we can get the build to reliably work.
