Yes of course, but that is what people programing NEON today for ARM
are doing, they have the ARM ARM open next to them and they try to
come up with optimal scheduling. Then compile and microbenchmark
and rinse and repeat. Whatever a future CPU/GPU architecture is going to
be, it will be a long time until compilers will be able to do that
