X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=28be7b33b959da0eccf8a24b72a441471b7df5f7;p=mesa.git tgsi_to_nir: Fix the TGSI ARR translation by converting the result to int. According to the TGSI spec, ARR needs to do a rounding and then a float-to-integer conversion which was missing. This patch also makes the rounding a bit more efficient by using nir_fround_even instead of the previous nir_ffloor+nir_fadd trick.
