From 79368ab302f925f705a02d60f09ea2d609628ce1 Mon Sep 17 00:00:00 2001 From: Connor Abbott Date: Thu, 1 Oct 2020 11:02:41 +0200 Subject: ttn: Fix number of components for IF/UIF NIR if statements only take one component, but TGSI registers are vec4. We're supposed to compare the x component, per https://docs.mesa3d.org/gallium/tgsi.html#opcode-IF.
