--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The optimization is performed optimistically anticipating followup
optimizations to make up for the immediate caused bloat (that's what I
understand). I'm not
sure if we make any attempt of assessing the possibility of that to happen
but certainly this transform could be disabled when optimizing for size or
for cold calls?
