Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rguenth at gcc dot gnu.org Version|unknown |11.1.1 Priority|P3 |P2 --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- IIRC one of the issues is that we do not have any strategy to expand memmove calls with bounded size inline. On GIMPLE we're only replacing memmove with constant power-of-two size (and properly aligned pointers depending on targets).
