--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note the question comes here is which is better using ldr/str followed by a few mult or ld3/st3 followed by a few shifts/adds. I think it depends on the micro-arch really (at least for aarch32). In fact I think ldr/str followed by a few mult is much better for ThunderX and most likely also Cortex-A57 (at least that is how I read the optimizing manual).
