--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
Gcc's register allocation is not well optimized for hard registers at function
boundaries (inlining makes this case not very important), there are several
related bug reports. It would be nice to improve that, but it is likely to get
lower priority than if you can find a similar issue in the middle of a hot
loop.
