Subject: [Qemu-devel] [PATCH v3 6/8] trace: switch to modular code generation for sub-directories
Date: Tue, 24 Jan 2017 11:01:49 +0000	[thread overview]
Message-ID: <20170124110151.937-7-berrange@redhat.com> (raw)
In-Reply-To: <20170124110151.937-1-berrange@redhat.com>

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.
