My recent episode with FireFox not running, got me using Firefox nightly. Firefox nightly has SIMD, but I have not been able to run my SIMD code or the code in Math.SIMD.ts for the longest time.
Finally, got to the bottom of it. Some of the objects are not the same name, 'float32x4' is now 'Float32x4'. Some of the functions are renamed, 'loadXYZ' is now 'load3'.
I changed my code, it needs some TLC, but it now executes. Did not edit math.SIMD.ts. What is the plan?
