--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- I remember we run into this issue in SPEC somewhere where an outer loop repeatedly triggers fault suppression on a masked store in an inner vectorized loop. The code in the vectorizer was contributed by Intel IIRC. Note fault suppression also happens for paging, not only for actual access violations.
