From dc68b920dfd1adf2616dda99da730e6412fe2e6e Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 1 Feb 2017 14:47:45 +1000 Subject: [PATCH] radeonsi/ac: move frag interp emission code to shared llvm code. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This code should be used in radv, so move it to a shared location in advance of doing that.
