Subject: freedreno/ir3: use r63.x for unused inputs
X-Git-Tag: upstream/19.0.0~3197
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e97b56172cd5f7f3ccc8a609713e556a8b9552ec;p=platform%2Fupstream%2Fmesa.git

freedreno/ir3: use r63.x for unused inputs

This way, unused sysval inputs, like frag_vcoord, get the correct regid
value to disable the input.
