From c3d802d68e222bf4030ab4e487501dfbcb34608d Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 5 Jan 2018 18:50:14 -0800 Subject: [PATCH] i965: Use UD types for gl_SampleID setup We already had to switch all of the W types to UW to prevent issues with vector immediates on gen10. We may as well use unsigned types everywhere.
