From 732246701f58a6be4bd377fbd2ecf1f10737824e Mon Sep 17 00:00:00 2001 From: Gert Wollny Date: Wed, 21 Jun 2017 10:05:23 +0200 Subject: mesa/st: glsl_to_tgsi move some helper classes to extra files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To prepare the implementation of a temp register lifetime tracker some of the classes are moved into seperate header/implementation files to make them accessible from other files. Specifically these are: class st_src_reg; class st_dst_reg; class glsl_to_tgsi_instruction; struct rename_reg_pair; int swizzle_for_type(const glsl_type *type, int component); as inline: bool is_resource_instruction(unsigned opcode); unsigned num_inst_dst_regs(const glsl_to_tgsi_instruction *op); unsigned num_inst_src_regs(const glsl_to_tgsi_instruction *op); Reviewed-by: Nicolai Hähnle --- src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp | 196 +++++++++++++++++++++ 1 file changed, 196 insertions(+) create mode 100644 src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp (limited to 'src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp') diff --git a/src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp b/src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp new file mode 100644 index 00000000000..0075ae86766 --- /dev/null +++ b/src/mesa/state_tracker/st_glsl_to_tgsi_private.cpp @@ -0,0 +1,196 @@ +/* + * Copyright © 2010 Intel Corporation + * Copyright © 2011 Bryan Cain + * Copyright © 2017 Gert Wollny + * + * 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.
