# Tests live in generic/ and in a directory per architecture.  A run executes
# generic/ plus the one matching this architecture, so a test which cannot
# apply here is not run rather than reporting a skip; what was left out is
# reported once, as a comment, so differing coverage is still visible.
#
# The harness checks the environment once up front and fails the run if the
# suite cannot execute, rather than letting every test skip and exit 0.
