[Mesa-dev] [PATCH 00/12] Fixes and partial redundancy elimination for compares

[Ian Romanick]

This is mostly a resend of an earlier series.  After I sent out the
original series I noticed that it uncovered a couple pre-existing bugs.
Patches 2, 3, and 4 are new, and they address these bugs.

Patches 5 and 6 are also new.  These patches prevent
nir_opt_peephole_select from removing flow control around indirect loads
of uniforms and shader inputs.  This by itself would have prevented the
discovery of the earlier bugs.

Patch 7 has had minor updates to comments.

The other patches remain unchanged from the first time I sent them out.

The whole series was tested (including shader-db results) on top of a
bunch of other patches that I also have out on the list.  The combined
branch is available at:
