From: Timur Kristóf Date: Wed, 25 Sep 2019 12:05:19 +0000 (+0200) Subject: amd/common: Move ac_export_mrt_z to ac_llvm_build. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d8b46f8964782b6f1fafb574447f1605e40e394f;p=mesa.git amd/common: Move ac_export_mrt_z to ac_llvm_build. The aim of this commit is to keep ac_shader_util LLVM-free, since we would like to use it in ACO later.
