--- Comment #2 from Mikael Pettersson <mikpelinux at gmail dot com> --- Works with gcc-9.4, ICEs with gcc-10.3 and above. Git bisect identified # first bad commit: [9b75f56d4b7951c60a656396dddd4a65787b95bc] Apply maximum nunits for BB SLP as the cause of the ICEs, though it possibly only exposed a latent target issue.
