A quick dive into the Plan9 assembly I picked up while developing my SIMD package for Go, and how it led to a 450% performance boost in calculations.

Relevant to which processors go supports, is this section (1). Base x64 support includes SSE and SSE2. I don't know if the go compiler produces it, though. Unlike extremely complex compilers like gcc, where performance is the top priority, the go compiler favours simplicity in a Wirthian(2) fashion favouring a simple, fast compiler.

I think in practice every chip since about 2008 or so has supported SSE4.1
