--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #7) > So my reduced testcase fails for aarch64 since GCC 12 but for x86_64 only on > the trunk. I suspect the commit that it will bisect to on x86_64 is just > enabling the pattern for x86_64. > > So if anyone does a bisect, please try on aarch64. Note also use `-O3 -fno-vect-cost-model` for the options since -O2 might catch when the vectorizer is turned on for -O2.
