Subject: freedreno/ir3: ignore clip-vertex varying
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f15447e7c9dc1e00973b02098637da0aa74de7d5;p=mesa.git

freedreno/ir3: ignore clip-vertex varying

Since we emulate clip-planes, the clip-vertex is used within the VS
itself (thanks to nir_lower_clip).  So just ignore it as a VS output.
Fixes a boatload of piglit tests that were asserting on unknown
varying slot.

(Also unrelated spelling/typo fix.)
