@elliottt I think these copy_reg uses are all remnants from back when register pairs were using non-allocatable registers (%r0 / %r1), and it wasn't safe to use those in anything but a copy_reg. But this has long since been changed, and regpairs now are just a pair of normal SSA registers, so I agree these copy_regs can all go away. Thanks!
