No real flags are defined, only the macros and functions. VREND_DEBUG(flag, ctx, ...) translates to fprintf(stderr, ...) that is enabled based on whether logging is enabled for flag in context ctx VREND_DEBUG_EXT(flag, ctx, X) can be used to add code sequenses as X, e.g. specific logging calls like for streams. v2: Make use of variadic macros to make the VREND_DEBUG macro more like a call to *printf (Following a suggestion by Gurchetan) v3: Already include debug header in vrend_renderer.c Reviewed-by: Gurchetan Singh <gurchetansingh@chromium.org> Tested-by: Jakob Bornecrantz <jakob@collabora.com> Signed-off-by: Gert Wollny <gert.wollny@collabora.com> Signed-off-by: Jakob Bornecrantz <jakob@collabora.com>macos/master
