uweigand commented on issue #6253:
@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 acopy_reg
. But this has long since been changed, and regpairs now are just a pair of normal SSA registers, so I agree thesecopy_reg
s can all go away. Thanks!
