Autogenerated code in trace.h/trace.c and friends is specific to the config-host.mak TRACE_BACKENDS setting and must be regenerated when ./configure --enable-trace-backend= changes settings. This patch ensures that changes to TRACE_BACKENDS are detected. For example, the trace-root.h file is now updated after switching trace backends: $ ./configure && make $ cp trace-root.h /tmp/old-trace-root.h $ ./configure --enable-trace-backend=simple && make $ diff -u /tmp/old-trace-root.h trace-root.h Reported-by: NChristophe Lyon <christophe.lyon@st.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com> Reviewed-by: NPhilippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: NDaniel P.
