Sounds good. You need 12 for the 6 VM registers A,C,E and X,Y,Z. L and S may be in a 32-bit register each, pointing into the stack. Then some more for temporary stuff. > I will have to look at the arm64 / ppc64 - do you assign machine > register for each VM register? Better, but you could as well put some of them into global memory. Probably not necessary here. > there any VM details published? Only doc64/asm, and the sources in src64/arch/ I think. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
