there's arm/intel-specific .c source that uses neon or sse intrinsics; we'll want similar for risc-v.

New implementation of checks for intel intrinsics with XGETBV64 and CPUID64 broke the builds on windows and msys.

Using fedora34, gcc 11.1.1
immintrin.h seems to invoke the errors in picojson.h.

would be great to have the Dirac operator with AVX intrinsic functions...
- do both, gcc and icc understand the same syntax?

Currently `parallel_for_workgroup` is implemented for intel devices, but will not work on Xilinx devices. It should hopefully be a very easy fix, but it's low priority for us at the time of writing th…

In Unity there is a very useful thing they've done with their intrinsics libraries: reference C# implementation.
For example Sse2.CompareGreaterThan (mm_cmpgt_epi16) looks like this (taken from htt…
