[Mesa-dev] [PATCH 0/6] nir: Cleanups for opt_algebraic

[Jason Ekstrand]

This little series provides some cleanups for opt_algebraic.  The most
important of which is adding descriptions to a bunch of the asserts in the
bit-size checker.  I've only gotten through about half of it so there's
still more work to do but it should make the error messages printed out
much less opaque to the average reader.  I can't count the number of times
in the last year or so that someone has come to me asking why their
obviously correct optimization fails validation.  Hopefully, this will make
working on nir_opt_algebraic even easier.
