--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
There is nothing to sink really, loop header copying introduces a PHI and
there's not partial redundancies but only partial-partial and those are not
obvious to CSE because of the introduced PHI.
I believe we have to teach SRA to decompose 'cur' and maybe also 'stack',
there's no scalar optimization going to do it also because we have aggregate
copies involved.
