--- Comment #2 from Jennifer Schmitz <jschmitz at gcc dot gnu.org> --- Thanks for looking into this. The regression looks to have been resolved by: AArch64: Enable early scheduling for -O3 and higher (PR118351) On our machines, the runtimes are back to normal. Do you still see the regressions? If not, feel free to close the ticket.
