# Test Machine interface (MI) operations
#
# Test MI watchpoint commands.
#
# The goal is not to test gdb functionality, which is done by other
# tests, but to verify the correct output response to MI operations.
# 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.
