Hi,

It seems that LLVM recognize the following CPU as being Skylake and generates
instructions for it that it can't decode.

https://www.intel.com/content/www/us/en/products/processors/pentium/4415y.html?_ga=2.61427049.456146392.1555206399-1251997790.1555206399

The issue has been reported on Windows using a Microsoft Surface Go base model
(4gb RAM, Intel Pentium Gold 4415Y processor) laptop.

Regards,
Alexandre
