No change. On that cpu and os, I observed such strange facts: - complex addressing costs sometimes noticeably - aligning jump positions rarely helps - trying to hide latency of operations often doesn't result in measurable changes (but I guess it does on other cpus) All in all, I could have recovered those cycles maybe by doing a reverse scan, but at this point the validation didn't seem worth the very marginal and hypothetical gain. -- Christophe _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
