# Run herd7 tests on all .litmus files in the litmus-tests directory
# 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.
#
# If the --hw argument is specified, this script translates the .litmus
# C-language file to the specified type of assembly and verifies that.
# But in this case, litmus tests using complex synchronization (such as
# locking, RCU, and SRCU) are cheerfully ignored.
#
# Usage:
# checkalllitmus.sh
#
# Run this in the directory containing the memory model.
#
# This script makes no attempt to run the litmus tests concurrently.
