> This is the first news I've seen on HN in weeks that I am genuinely excited about! I have several AVX-2 hobby projects in Common Lisp, and an AVX-512 machine. It's an unexpected surprise to read this morning that this very useful ISA is suddenly unlocked. I'll be trying it out right away. Nice to hear! :) It is the basic compiler support, and lots of instructions added. However, you can't use knor, knoq and similar since they require scheduling of k-masks. Not done yet. But you can certainly use some of avx512 instructions and add yourself if you need some that is not available already. Check https://github.com/sbcl/sbcl/blob/master/src/compiler/x86-64.... |
