I love me some isa extension, I'd love to know what these are intended and useful for for though. 1 bit inference? I hear they could be useful in crypto as well, but that's out of my field.
I believe this means "VBMACXOR16X16X16" is now officially the longest x86 mnemonic
It almost reads like "visual basic macro 16x16x16". And if you told me the x86 ISA had instructions to speed up visual basic commands, I would believe it.
