Subject: [committed] Add testcase for already fixed PR (PR tree-optimization/83283)
Date: Tue, 05 Dec 2017 13:36:00 -0000 [thread overview]
Message-ID: <20171205133622.GV2353@tucnak> (raw)
Hi!
This testcase has been fixed by r253146 but that testcase is quite different
from this one, so I've committed this to trunk as obvious.
