--- Comment #3 from Renato Golin <renato.golin at linaro.org> ---
Oh, you're right! I honestly didn't pay attention to this when I did the
triage.

This is less of an optimisation and more of a success story of our register
description knowing about register aliasing, so the allocator can take better
decisions.

Closing as not a bug. Thanks for the analysis!
