I think you saw, but I have a bunch more that I needed for nvc0 at:

https://github.com/imirkin/mesa/commit/31e9ecd461674d979ce80537ba4cb9b453a35018.patch

And a few follow-ons which will allow selectively adding them a group
at a time depending on the caps (one for dround & co, one for
dldexp/dfracexp):

Sorry, no docs :(

Feel free to fold/whatever into your change.
