Helped: Providing specific CPU architecture and instruction set details.
Got in the way: Hallucinated a non-existent built-in function initially.
… It did fine, except for declaring that our CPU provided a built in that doesn't exist. When I stated my CPU was an intel chip with avx512 and I needed an implementation of this function for avx512..it happily write the required assembler.
