Yes - just copy one from the same directory.  So for example have a look
at gas/testsuite/gas/rx/pr19665.s.  Create a similar file called pr22737.s
containing the .ascii directive mentioned in comment #1.

The look at pr19665.d (in the same directory) and use it as a template to
create pr22737.d.  Use the output from disassembling the assembled version
of pr22737.s as the body of pr22737.d, but remember that you are dealing with
regular expressions, so you may need to escape some of the characters.

Next edit rx.exp (also in the same direcctory) and add this line at the bottom:

  run_dump_test "pr22737"

Now the gas testsuite with your patched toolchain and make sure that the
new test runs and passes.  (ie: "cd gas ; make check").  That should be it.
