From ac8fb9800a8b20ffa6c3eea1c7b7212d2cc79b40 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 31 Mar 2016 15:49:55 +1000 Subject: [PATCH] r600: add support for vertex fetches via texture cache On evergreen we can route vertex fetches via the texture cache, and this is required for some images support. So add support to the asm builder for it.
