X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=d13059f4d50d370eec76495dd2b51fdf5c6e1aee nouveau: Use nir_lower_doubles instead of lower_fmod64 on nvc0. We currently have two duplicate mechanisms for lowering fmod@64. One is a nir_opt_algebraic rule keyed off of options->lower_fmod64, and the other is nir_lower_doubles, which offers a full gamut of fp64 lowering. The latter works slightly better in some corner cases, so I'm trying to eliminate lower_fmod64 and drop the redundancy.
