From 700bebb958e93f4d472c383de62ced9db8e64bec Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 28 Feb 2017 09:10:43 -0800 Subject: i965: Move the back-end compiler to src/intel/compiler Mostly a dummy git mv with a couple of noticable parts: - With the earlier header cleanups, nothing in src/intel depends files from src/mesa/drivers/dri/i965/ - Both Autoconf and Android builds are addressed. Thanks to Mauro and Tapani for the fixups in the latter - brw_util.[ch] is not really compiler specific, so it's moved to i965. v2: - move brw_eu_defines.h instead of brw_defines.h - remove no-longer applicable includes - add missing vulkan/ prefix in the Android build (thanks Tapani) v3: - don't list brw_defines.h in src/intel/Makefile.sources (Jason) - rebase on top of the oa patches [Emil Velikov: commit message, various small fixes througout] Signed-off-by: Emil Velikov Reviewed-by: Jason Ekstrand --- src/intel/compiler/gen6_gs_visitor.h | 91 ++++++++++++++++++++++++++++++++++++ 1 file changed, 91 insertions(+) create mode 100644 src/intel/compiler/gen6_gs_visitor.h (limited to 'src/intel/compiler/gen6_gs_visitor.h') diff --git a/src/intel/compiler/gen6_gs_visitor.h b/src/intel/compiler/gen6_gs_visitor.h new file mode 100644 index 00000000000..1bdcf925880 --- /dev/null +++ b/src/intel/compiler/gen6_gs_visitor.h @@ -0,0 +1,91 @@ +/* + * Copyright © 2014 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
