Shouldn't this have failed to compile ? thanks -- PMM

This code is guarded by DEBUG_ROCKER, which is why I didn't noticed :) Indeed when enabling: ../../hw/net/rocker/rocker.c:930:65: error: extraneous ')' before ';' snprintf(buf, sizeofbuf), "Ring[%s] ADDR", ring_name); ^

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1, resulting in painful developper experience. Use snprintf() instead. Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> --- hw/net/rocker/rocker.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-)
