i965 has a similar restriction, and it handles it by calling
nir_lower_io_to_temporaries() before nir_lower_io(), which does
exactly what you'd expect. I think radeonsi should probably use that
pass too. That will require us to call nir_lower_io() inside the
driver inside the state tracker, which now that I think about it, I
feel better about -- when Rob originally implemented st_glsl_to_nir, I
thought it would be better to push nir_lower_io down to the drivers
and let them set driver_location, but he disagreed since (IIRC)
Gallium has a fixed uniform/VBO layout that drivers need to respect,
so it wouldn't be that helpful for drivers to control the location
anyways. But now that we want to use the same compiler stuff for
Gallium and another API, we might want to reconsider that. It would be
nice if driver_location had a shared meaning across radeonsi and radv,
and we left location to mean the API location, and considered Gallium
to be just another API. I think this would also be a requirement for
any potential i965 Gallium driver. What do you think?
