From 954cf8e86b6e0d52c04098604d2daa4305bf6f70 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 26 Feb 2020 07:03:33 +1000 Subject: [PATCH] gallivm/tgsi: fix stream id regression This broke TGSI GS shaders with llvmpipe, it wasn't looking at the right immediates and it should be cast to an integer type.
