Currently, packages like CUDA.jl were using the
emit_
functions directly because they needed access to more intermediate forms of compilation results. That's a pity though because those methods are more unstable, e.g.,emit_julia
getting removed in #417.In this PR, I'm making it so that more stuff is returned when calling the main compilation driver's entrypoint,
GPUCompiler.compile
. That should make it possible to avoid calling into anyemit_
function, hopefully reducing breakage in the future.As part of this PR, I'm slightly simplifying the compilation hook design such that we don't need to check for it explicitly from the compilation cache.
