Subject: intel/compiler: store the FS inputs in WM prog data
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=460de2159e2aa8e67f216d9ad8e9ce00cc8c9679;p=mesa.git

intel/compiler: store the FS inputs in WM prog data

Store the fragment shader inputs in the program data so we can use them
later when required without needing the NIR shader.
