From e7d1e99543dcc8e2d939ebfcfd332d2c480170a2 Mon Sep 17 00:00:00 2001 From: Quentin Colombet Date: Tue, 26 Apr 2016 23:55:41 +0000 Subject: [PATCH] [MachineInstrBundle] Update the comment for PhysRegInfo::DeadDef. I missed read the comment when I commited r267621 and thought the comment did not need update. Matthias kindly proved me wrong.
