> "Another reason we use assembly over a high-level language is to use instructions that C or C++ cannot really use. For example, the advanced vector extensions (AVX) for an Intel processor don’t have a 1-to-1 conversion from C." This might be beyond the scope of the article, but it may be worth noting https://ispc.github.io/ https://ispc.github.io/, which is a C language extension and accompanying (LLVM-frontend) compiler. ISPC exposes an SPMD programming model that efficiently maps to the CPU's vector lanes (think CUDA kernels, but running on those vector lanes instead of a GPU). Except for a few new keywords and some library functions, it is almost identical to C and has C linkage.
