/* You should use these macros to mark if blocks where the if condition

*
* This will inform human readers of this fact, and will also inform
* the compiler, who will in turn inform the CPU.
*
* CPUs often start executing code inside the if or the else blocks
* without knowing whether the condition is true or not, and will have
* to throw the work away if they find out later they executed the
* wrong part of the if.
*
* If these macros are used, the CPU is more likely to correctly predict
* the right path, and will avoid speculatively executing the wrong branch,
* thus not throwing away work, resulting in better performance.
*
* In light of this, it is also a good idea to mark as "likely" a path
* which is not necessarily always more likely, but that will benefit much
* more from performance improvements since it is already much faster than
* the other path, or viceversa with "unlikely".
*
* Example usage:
* if(unlikely(do_we_need_a_software_fallback()))
* do_software_fallback();
* else
* render_with_gpu();
*
* The macros follow the Linux kernel convention, and more examples can
* be found there.
*
* Note that profile guided optimization can offer better results, but
* needs an appropriate coverage suite and does not inform human readers.
