From e1b3be7ced2f6c036dce456de16886451b205791 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Thu, 6 Jun 2019 19:31:14 -0300 Subject: [PATCH 1/3] shader: Move Node declarations out of the shader IR header Analysis passes do not have a good reason to depend on shader_ir.h to work on top of nodes. This splits node-related declarations to their own file and leaves the IR in shader_ir.h --- src/video_core/CMakeLists.txt | 1 + src/video_core/shader/node.h | 510 ++++++++++++++++++++++++++++
