477  * (the PC before the pmove statement points to the virtual address of
478  * the code). Getting that physical address is not hard, but the code
479  * becomes a bit complex since I've tried to ensure that the jump
480  * statement after the pmove is in the cache already (otherwise the
481  * processor can't fetch it!). For that, the code first jumps to the
482  * jump statement with the (virtual) address of the pmove section in
483  * an address register . The jump statement is surely in the cache
