To everyone skeptical of people saying that it's better to separate CPU and GPU code into separate files, riddle me this: With this system, how do we specify whether dependencies are needed to be compiled for the CPU, GPU, or both? ---- Technically I don't know really care whether it's multiple files or one, I just want to make sure we are not reinventing a shittier version of CFG. What they are providing looks to me like: 1. explicitly annotate some things as `cfg(GPU)` or ungated (both) 2. unlabeled means annotated `cfg(not(GPU))` by definitely Put this way, this has nothing to do with GPUs, and just has to do with creating some crate-local CFG shorthanded. Great! Let's do that first, get a solid foundation, and then come back to whatever is remaining for CUDA Rust.
