# This tests all the miscellaneous components of backend support
# against whatever this build is running on.  A platform will fail
# this test if it is missing parts of the backend implementation.
#
# As new backend code is added to satisfy the test, be sure to update
# the fixed test cases (run-allregs.sh et al) to test that backend
# in all builds.
