From 0ab8ed18a6fe98bfc82705b0f041fbf2a8ca5b60 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Wed, 25 Jan 2017 16:14:15 +0000 Subject: [PATCH] trace: switch to modular code generation for sub-directories Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir. Reviewed-by: Stefan Hajnoczi Signed-off-by: Daniel P.
