From 26bc60ac82f88d14e65be5387eb4a136edf94f1b Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Thu, 17 Sep 2015 19:23:54 +0300 Subject: replay: introduce icount event This patch adds icount event to the replay subsystem. This event corresponds to execution of several instructions and used to synchronize input events in the replay phase.
