# Run rtems tests on the c4x simulator built into gdb
# This program generates a simulator script to run each test
# Typically the test is then run, although it can be generated
# and left as a file using -s
#

# progname=`basename $0`
progname=${0##*/}        # fast basename hack for ksh, bash

USAGE=\
"usage: $progname [ -opts ] test [ test ... ]
        -o options  -- specify options to be passed to simulator
        -v          -- verbose
        -s          -- generate script file (as 'test'.ss) and exit
        -l logdir   -- specify log directory (default is 'logdir')

  Specify test as 'test' or 'test.exe'.
  All multiprocessing tests *must* be specified simply as 'mp01', etc.
