[Openmp-dev] Where are the ICV and runtime functions defined?

[Daniel Schürmann via Openmp-dev]

Hello together,

now, that I'm making progress with my OpenCL/SPIR-V implementation (I 
got a running subset with proper parallelisation), I seem to get blind 
on both eyes when it comes to finding things.

I would be very thankful, if someone could tell me, where to implement 
the ICVs and runtime functions (I mean the ones defined in the 
specification). Or are they implemented once and not per target platform?

Also, I'm not sure, if the runtime functions should be callable from 
target region, but it seems so. This would mean that I have to write 
some SPIR-V functions for each declared function in omp.h. Where do I 
put these?

Thanks in advance,
Daniel
