[Mesa-dev] Draft ARB_parallel_shader_compile RFC

[Ilia Mirkin]

The whole point of this extension is to allow applications to query
compilation status without stalling, waiting for the compile. That
means that glCompileShader/glLinkProgram should return immediately
while the real work proceeds in the background. I don't think you've
done that here.

As an aside, did you test this? I'm pretty sure the
MaxShaderCompilerThreadsARB entrypoint is unreachable.
