From dc70c86b9b485cb5006a55cc2efd1f154dbfd469 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg=20Kristensen?= Date: Fri, 4 Sep 2015 16:35:34 -0700 Subject: [PATCH] i965: Move compute shader code around MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This moves the compute shader code around in order to make the way the code is split up more consistent. There should be no functional changes. Typically we have a few files per stage: brw_vs.c, brw_wm.c brw_gs.c: code to drive code generation and implement precompiling and cache search. genX__state.c gen specific implementation of the state emission for the shader stage. The brw_*_emit() functions are all in the same files as the visitor classes they use (with the exception of VS, which may use either vec4 or fs). To make compute follow this convention, we move the brw_cs_emit() function into brw_fs.cpp. We can then rename brw_cs.cpp to brw_cs.c and do this in C like the other similar files. Finally, move state setup and atoms to gen7_cs_state.c.
