-/**

- * @brief   Exotic optimization.

- * @details If defined then a CPU register is used as storage for the global

- *          @p currp variable. Caching this variable in a register greatly

- *          improves both space and time OS efficiency. A side effect is that

- *          one less register has to be saved during the context switch

- *          resulting in lower RAM usage and faster context switch.

- *

- * @note    This option is only usable with the GCC compiler and is only useful

- *          on processors with many registers like ARM cores.

- * @note    If this option is enabled then ALL the libraries linked to the

- *          ChibiOS/RT code <b>must</b> be recompiled with the GCC option @p

- *          -ffixed-@<reg@>.

- * @note    This option must be enabled in the Makefile, it is listed here for

- *          documentation only.
