thanks for looking at this!
I fixed frame_ppc and ppc.ad. I also use R1_SP
But I left the use of the registers as is. As the registers
spilled contain 'real' values and can only be used as
temp after they are spilled. I think this is expressed by
the current wording quite well.

the change looks good.
I have just a few minor remarks:
- please update the copyright year
- you removed UseNewFastLockPPC64 - can you please also remove the
last occurrence in ppc.ad
- once you already declared the various temp registers, maybe you can
also use these temp names for spilling? This could avoid potential
problems if somebody changes one of the temp registers. And you could
also use R1_SP instead of R1 to make it more clear that R1 is the SP.
