X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d6019302eb772b1c399cecc3f5abf1940f0c0d0;p=mesa.git vc4: Use NIR shader's num_outputs for generating our new output. Simplifies the code (we don't have struct or matrix varyings that would have previously made this code break), and makes sure we keep s->num_outputs accurate.
