* test__parse_no_sample_id_all - test parsing with no sample_id_all bit set.

*
|
* This function tests parsing data produced on kernel's that do not support the
|
* sample_id_all bit. Without the sample_id_all bit, non-sample events (such as
|
* mmap events) do not have an id sample appended, and consequently logic
|
* designed to determine the id will not work. That case happens when there is
|
* more than one selected event, so this test processes three events: 2
|
* attributes representing the selected events and one mmap event.
|
*
|
* Return: %0 on success, %-1 if the test fails.
