-/* You should use these macros to mark if blocks where the if condition
- * is either likely to be true, or unlikely to be true.
- *
- * 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.
