It's not needed to rsave()/rsavex() before an asm subroutine that clobbers the X register
(which is used by prog8 as the internal evaluation stack pointer);
the compiler will take care of this situation automatically.
Note: the 16 bit 'virtual' registers of the Commander X16 are *not* saved.

but you can use ``cx16.save_virtual_registers()`` for that.
rrestore, rrestorex
Restore all registers including status (or only X) back from the cpu hardware stack
