From: Iago Toral Quiroga Date: Tue, 29 Oct 2019 07:32:44 +0000 (+0100) Subject: v3d: rename vertex shader key (num)_fs_inputs fields X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e7e501efceca73b92727e9d295eda63d21e76afe;p=mesa.git v3d: rename vertex shader key (num)_fs_inputs fields Until now this made sense because we always paired vertex shaders with fragment shaders, but as soon as we implement geometry and tessellation shaders that will no longer be the case, so rename this to (num_)used_outputs. v2: Use 'used_outputs' instead of ns_outputs, which is more explicit (Eric).
