This commit makes checklitmus.sh and checkalllitmus.sh check to see if a hardware verification was specified (via the --hw command-line argument, which sets the LKMM_HW_MAP_FILE environment variable). If so, the C-language litmus test is converted to the specified type of assembly-language litmus test and herd is run on it. Hardware is permitted to be stronger than LKMM requires, so "Always" and "Never" verifications of "Sometimes" C-language litmus tests are forgiven. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

# Run a herd7 test and invokes judgelitmus.sh to check the result against
|
|
# a "Result:" comment within the litmus test. 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:
|
|
# checklitmus.sh file.litmus
|
|
#
|
|
# Run this in the directory containing the memory model, specifying the
|
|
# pathname of the litmus test to check. The caller is expected to have
|
|
# properly set up the LKMM environment variables.
