From: Thiago Macieira Date: Thu, 30 Aug 2018 15:59:41 +0000 (+0000) Subject: x86: Move AESNI generation to Skylake and Goldmont X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a73e818148ff2aa784a6691ec2d021ed07787e48;p=gcc.git x86: Move AESNI generation to Skylake and Goldmont The instruction set first appeared with Westmere, but not all processors in that and the next few generations have the instructions. According to Wikipedia[1], the first generation in which all SKUs have AES instructions are Skylake and Goldmont. I can't find any Skylake, Kabylake, Kabylake-R or Cannon Lake currently listed at https://ark.intel.com that says "Intel® AES New Instructions" "No".
