--- Comment #2 from Geza Lore <glore at igalia.com> ---
On ARMv7 sometimes we need both scratch registers reserved for the macro assembler, so the best we might be able to do is a RELEASE_ASSERT when we handed out the scratch GPR but then end up needing it. Still would be better than the current situation. Other than that caveat, we could add support for this.
