To follow up on this a bit... from what I got from a conversation with Oracle (incident review ID 2050428), they're treating it as a bug that -xvector=%none doesn't prevent this optimization, so that should suppress it in the future. In the meantime there's an undocumented option -W2,-Rbcopy that can suppress the optimization, or of course we can remove the loop (gerrit 4829). I don't really see why they're not going the route of an "hey I'm building for the kernel" flag and making the compiler deal, but eh. -- Andrew Deason adea...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
