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.

Is Plan9 in this context related at all to Bell Labs's Plan9? Seems too similar to be coincidence.

From https://go.dev/doc/asm:

> The assembler is based on the input style of the Plan 9 assemblers, which is documented in detail elsewhere. If you plan to write assembly language, you should read that document although much of it is Plan 9-specific.

That first sentence links to https://9p.io/sys/doc/asm.html. So yes, definitely not a coincidence.
