From 80dd5c4918aba98f025ca60c838dd68b6e33ff0e Mon Sep 17 00:00:00 2001 From: Daniel P. Berrange Date: Tue, 4 Oct 2016 14:35:59 +0100 Subject: trace: introduce a formal group name for trace events The declarations in the generated-tracers.h file are assuming there's only ever going to be one instance of this header, as they are not namespaced. When we have one header per event group, if a single source file needs to include multiple sets of trace events, the symbols will all clash. This change thus introduces a '--group NAME' arg to the 'tracetool' program. This will cause all the symbols in the generated header files to be given a unique namespace. If no group is given, the group name 'common' is used, which is suitable for the current usage where there is only one global trace-events file used for code generation.
