Ok you can start by using
linuxthreads/sysdeps/powerpc/powerpc64/pt-machine.h as an example to start
with. Also you need to look at sysdeps/powerpc/powerpc32/[setjmp.S,
__longjmp.S, /fpu/setjmp.S, /fpu/__longjmp.S]. This is one place (that I
can think of) where the handling of r2 needs to chance ... :)
