16 | # This file was written by Chris Demetriou (cgd@google.com). |
17 | # It tests printing of thread event (start, exit) information, and | |
18 | # disabling of those messages. | |
19 | # | |
20 | # Note: the format of thread event messages (and also whether or not | |
21 | # messages are printed and can be disabled) is dependent on the target | |
22 | # thread support code. | |

25 | # to be generalized to support other targets | |
