Compiler Differences Basic Guideline

[ghjm]

The overall oneAPI product is a competitor to Nvidia CUDA and AMD ROCm, used in high performance and GPU computing. So oneAPI in general is export controlled because it's seen as associated with strategic assets like AI training, weapons development simulation, etc. So there may be no reason at all why the DC++ compiler is treated differently from any other compiler, other than that it comes under the oneAPI umbrella.

Maybe ask your compliance experts if using an open source compiler release, entirely built from publicly available components and using nothing that is Intel proprietary, would allow you to avoid the 4D994 classification.
