Re: [m68k] register renaming not properly tracking used registers

Thanks, I've committed your patch on mainline (with a couple of
trivial spacing fixes).
I'd also like to backport it to 3.4, with Mark's approval.
Does it fix a regression?
BTW, I *completely* messed up the date in the ChangeLog entry...
I had it fixed before committing ;-)
I don't know if its a regression.
I'm not sure too, but nevertheless, it's a miscompilation
bug for a documented feature (the interrupt_handler attribute).
The fix is m68k-specific and it doesn't alter generated code
unless the interrupt_handler attribute is being used.
