I haven't spent a ton of time down this particular rabbit hole, but now I may have to.
How are they using gcc and clang at the same time?
Interesting question. I don't know. I haven't actually had a chance to dig in yet.

@waz @soaska There are other reasons to be cautious about using AVX - older CPUs that support it are forcibly downclocked when the instructions are used so you'd better make sure that your vectorised loops are delivering enough benefits for the 10-20% penalty for all the rest of the code

Ohh, cool. Thanks for the warning. This just got complicated enough that I am definitely going to have do go down this rabbit hole.
