From ca3fa0e88f3a8e22f774751bcb10cc205772c2fc Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 4 Oct 2016 14:35:54 +0100 Subject: trace: dynamically allocate event IDs at runtime MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of having the code generator assign event IDs and event VCPU IDs, assign them when the events are registered at runtime. This will allow code to be generated from individual trace-events without having to figure out globally unique numbering at build time.
