On recent Intel CPU, the byteswapping comes for free (MOVBE instruction). About the unaligned access it's actually the reverse. The fact that aarch64 does unaligned access means they have to go through the slow path (I have posted a patch to improve that). On sparc given that all access are aligned means there are more chances to go through the fast path. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
