21  * This test excercises the "remnant" handling of the temporal option.
22  * At the end of one pass of retrieving and printing data from all CPUs,
23  * some unprocessed data will remain, because its timestamp is after the
24  * time covered by all CPUs' buffers.  This unprocessed data is
25  * rearranged in a more space-efficient manner.  If this is done
26  * incorrectly, an alignment error may occur.  To test this, we use a
27  * high-frequency probe so that data will be recorded in subsequent
28  * CPU's buffers after the first CPU's buffer is obtained.  The
29  * combination of data traced here (a 8-byte value and a 4-byte value)
30  * is effective to cause alignment problems with an incorrect
31  * implementation.
32  *
33  * This test needs to be run on a multi-CPU system to be effective.
