Sorry to get in the wagon that late, but where is this used? Shouldn't
it be part of the patch, too?

Eli, as far as I know, EHABI doesn't use NEON registers for exception
handling, so if this is just for EH, it should be safe to assume 0-15.

Also, ARM has more than 16 integer registers, but they're accessible
in different modes, and always addressable via r0-r15 (except the xPSR
and co-processors, which again, I don't think they're used for EH). So
it should be safe to assume this range.

cheers,
