The half-wave scan rules for 32-lane hosts made lane 31 of a matched scan a subgroup reduction and threw on a device without subgroup arithmetic, where the read used to build as a shuffle of the scan. Such a device now keeps the shuffle for lane 31; lane 63 still reads the identity, which needs no arithmetic. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
