Thanks Laurent,
Pretty much what I ended up with, so it seems there is no builtin save/restore function on interrupt...
However I am a bit curious why you interleave r0/r1 fetches? Is it related to other stuff you are doing, not visible here?
I suppose it avoids an ugly nop, but does require one extra move at the end.
I guess it's mostly immaterial in real terms, I'm just curious. :)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
