On Intel GPUs, "shared" maps to a concept called "Shared Local Memory". So I tend to think of it as memory :) It's not perfect, though. While most shader_in/shader_out end up being thread-local, shader_out in a TCS is actually shared across threads (and pre-dates the shared keyword). I'm sort of inclined to leave that alone for now unless you think we ought to do something about it. > > We may also want to rename the nir->globals list, or > > nir_lower_global_vars_to_local and nir_opt_global_to_local.
