Subject: [PATCH] icount: fix shift=auto for record/replay
Date: Wed, 06 May 2020 10:52:26 +0300	[thread overview]
Message-ID: <158875154623.957.4036561733593052357.stgit@pasha-ThinkPad-X280> (raw)

This patch fixes shift=auto when record/replay is enabled.
Now user does not need to guess the best shift value.
