21# This tests all the miscellaneous components of backend support
22# against whatever this build is running on.  A platform will fail
23# this test if it is missing parts of the backend implementation.
24#
25# As new backend code is added to satisfy the test, be sure to update
26# the fixed test cases (run-allregs.sh et al) to test that backend
27# in all builds.
