(Why are they separate though?  It could just be one loop var).

Yes it could just be a single loop var, but in that case it would have 
to be reset at the start of the second loop, which means we would have 
to pass 'addr' for resetting the loop anyway,

Right, I noticed that after hitting send, as usual.

so I opted to do it 
outside the inline asm by using to separate loop vars set to their 
starting value outside the inline asm.

The thing is, the way it is written now, it will get separate registers
for each loop (with proper earlyclobbers added).  Not that that really
matters of course, it just feels wrong :-)
