21 # disabling of those messages.
23 # Note: the format of thread event messages (and also whether or not
24 # messages are printed and can be disabled) is dependent on the target
25 # thread support code.
27 # This test has only been verified with Linux targets, and would need
28 # to be generalized to support other targets
