#
# Run herd tests on all .litmus files in the specified directory (which
# defaults to litmus-tests) and check each file's result against a "Result:"
# comment within that litmus test. If the verification result does not
# match that specified in the litmus test, this script prints an error
# message prefixed with "^^^". It also outputs verification results to
# a file whose name is that of the specified litmus test, but with ".out"
# appended.
#
# Usage:
# checkalllitmus.sh [ directory ]
#
# The LINUX_HERD_OPTIONS environment variable may be used to specify
# arguments to herd, whose default is defined by the checklitmus.sh script.
# Thus, one would normally run this in the directory containing the memory
# model, specifying the pathname of the litmus test to check.
#
# This script makes no attempt to run the litmus tests concurrently.
