Something which I found odd in the article:
In the beginning you write that "VBMI [...] is the only extension that we’ve seen before – it’s in Cannonlake." but later you write that "VPOPCNTDQ is older (from the MIC product line)"
So which is it? Or am I misunderstanding something?
- glangdale 7y agoAch, you're right. Just a mistake. I tend to forget the existence of any operations that are (a) in MIC and (b) not available for bytes, so this was a double-whammy and even after writing that sentence I forgot that I was contradicting myself.
