--- Comment #40 from Richard Biener <rguenth at gcc dot gnu.org> --- So I wonder if we can use "local costing" to decide a gather is always OK compared to the alternative with peeling for gaps. On x86 gather tends to be slow compared to open-coding it. In the future we might want to explore whether we can re-do costing for alternatives without re-running all of the analysis at least for decisions we know have only "local" effect.
