@thewilsonator I am working on creating the bindings for the math functions. I only have open cl 2.0 instead of open cl 2.1, which currently giving me difficultly.

IIRC 2.1 is when SPIR-V support was added and that is how LDC is able to target OpenCL at all.

What is your 2.0 device? My ancient Intel CPU is what I'm using for OpenCL.

Which has the OpenCL API Version 2.0
