Arjan van de Ven	99c7bba8e4	Initial support for SkylakeX / AVX512 This patch adds the basic infrastructure for adding the SkylakeX (Intel Skylake server) target. The SkylakeX target will use the AVX512 (AVX512VL level) instruction set, which brings 2 basic things: 1) 512 bit wide SIMD (2x width of AVX2) 2) 32 SIMD registers (2x the number on AVX2) This initial patch only contains a trivial transofrmation of the Haswell SGEMM kernel to AVX512VL; more will follow later but this patch aims to get the infrastructure in place for this "later". Full performance tuning has not been done yet; with more registers and wider SIMD it's in theory possible to retune the kernels but even without that there's an interesting enough performance increase (30-40% range) with just this change.	8 years ago
