Thu Dec 10 01:52:30 UTC 2015
Author: rrs
Date: Thu Dec 10 01:52:29 2015
New Revision: 292043
URL: https://svnweb.freebsd.org/changeset/base/292043
Log:
Fix several typos and bugs within pmcstudy. Also highlight the one SB test
that is failing (and is likely a problem in the actual PMC defintions). Add
to this also the -A option to run all canned tests.
