[swift-evolution] TrigonometricFloatingPoint/MathFloatingPoint protocol?

[Jacob Williams]

There’s also a PureSwift organization of GitHub that has several Swift PM packages built specifically with Linux support in mind

It looks like it’s along the lines of SwiftBreezy, but it hasn’t died out…yet.

At the same time, this may just be another example of how without an Apple “backed”/supported repo, the community is very likely to become more and more fragmented as more and more people implement the same few frameworks with minor variations/improvements.

There are no analogous instructions on ARM or PPC.
