Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Prefetching generally increases code size, so I think we shouldn't do it, at least not by default. So I'd say for !optimize_size -fprofile-use should just not add -fprefetch-loop-arrays.
