Was curious about this as well, especially that go does use FPATAN on 386 but not Amd64 - found this bug which explains the issues involved: https://github.com

- userbinator 9y agoAMD was far behind Intel (factor of 2-3x slower) in x87 implementation performance for a long time, and continues to be; no doubt that was one of the factors leading them to try to deprecate it when they designed AMD64.
- geezerjay 9y agoAre you seriously trying to claim that AMD felt compelled to invent a whole new CPU architecture just because you believe it couldn't implement FPATAN right?
