# Tests involving watchpoint conditions with local expressions.
#
# The skip_hw_watchpoint_tests checks if watchpoints are supported by the
# processor. On PowerPC, the check runs a small test program under gdb
# to determine if the Power processor supports HW watchpoints. The check
# must be done before starting the test so as to not disrupt the execution
# of the actual test.
