Hi,
Yes compiler do not optimize (remove out) empty function defined as is
suggested.
But if RIOT does not want use macros, we can define empty function as static
inline function in header and then will be removed by optimization.
log_api.h
#if MODULE_LOG
void log_info(...);
#else
static inline void log_info(...) {}
#endif
BTW. Hauke idea use modules is nice.
Regards,
Jozef
