Nope. They have AES on the die, but its not the AES-NI that's the topic here. AES-NI was added in 2010 in the Core-i5/i7 families and in 2012 in the AMD A10 cores. >> And even if they did, the default 10.x compiler would support it. > > Can't confirm that (yet), but I'll bet it's AOK. That's how this thread started. Full AES-NI support is in the default compiler (clang) in the base system for amd64 and i386 but there's missing pieces with the old built-in gcc+binutils. If you BYO newer version of gcc+binutils, that would work too. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com; KI6FJV bitcoin:188ZjyYLFJiEheQZw4UtU27e2FMLmuRBUE
