Author: Ian Romanick <[email protected]> Date: Thu Jan 28 18:15:26 2021 -0800 nir/algebraic: Mark some more logic-joined comparison reductions as exact If the values are known to be numbers, the the replacements are exact. This is only applied to the patterns with constants. Constants should always be numbers, and shaders with NaN constants should be handled in a different way. No shader-db or fossil-db changes on any Intel platform. The intention is to make these patterns more future proof.
