Research direction
Start with the referenced PR #82 diff, especially the linked context, and trace how register variables are handled there. Compare that path with normal GCC constraint code using suitable generated-code or performance checks. Done means establishing whether the approaches are equivalently efficient and recording any required follow-up.
