 4# Run herd7 tests on all .litmus files in the litmus-tests directory
 5# and check each file's result against a "Result:" comment within that
 6# litmus test.  If the verification result does not match that specified
 7# in the litmus test, this script prints an error message prefixed with
 8# "^^^".  It also outputs verification results to a file whose name is
 9# that of the specified litmus test, but with ".out" appended.
10#
11# If the --hw argument is specified, this script translates the .litmus
12# C-language file to the specified type of assembly and verifies that.
13# But in this case, litmus tests using complex synchronization (such as
14# locking, RCU, and SRCU) are cheerfully ignored.

16# Usage:
17#	checkalllitmus.sh
18#
19# Run this in the directory containing the memory model.
20#
21# This script makes no attempt to run the litmus tests concurrently.
