* new test IsProgramPipeline: check the Pipeline object state creation. GenPipeline only reserved name. I also take the opportunity to test negative value on glGenProgramPipelines and glDeleteProgramPipelines. Note: FGLRX don't follow the spec besides crash on glGenProgramPipelines because of -1... Note: Nvidia seems to crash on glDeleteProgramPipelines because of -1...
* new test mix_pipeline_useprogram: the goal is to test the state mix of glUseProgram/glBindProgramPipeline/glActiveProgram. Ian quote: "In this case, either the UseProgram state or the BindProgramPipeline state. If UseProgram sets a non-zero program, that state is used. Otherwise the BindProgramPipeline state is used.....In this case, I think AMD's behavior is incorrect." Note: Nvidia seems to be fine. * new test GetProgramPipelineiv: bind various stages (including geometry and tesselation to the pipeline and check the result with GetProgramPipelineiv. I take also the opportunity to use glCreateShaderProgramv. Note: I got an GL_INVALID_VALUE when glActiveShaderProgram is called with a program that isn't bound to any stage to the pipeline. For me there isn't such limitation in the spec but I could be wrong. Spec quote: "An INVALID_VALUE error is generated if program is not the name of ei- ther a program or shader object. An INVALID_OPERATION error is generated if program is the name of a shader object." General note: I duplicate the vertex shader for differents GL version. On GLSL 150+ built-in must be redeclared. However previous version doesn't support in/out block so it is up to the GLSL compiler to include them inplicitely. I try to force on older version of GLSL but it doesn't work on FGLRX and still need the redeclaration... --- tests/all.tests | 7 + tests/spec/CMakeLists.txt | 1 + .../arb_separate_shader_objects/CMakeLists.gl.txt | 14 + .../arb_separate_shader_objects/CMakeLists.txt | 1 + .../GetProgramPipelineiv.c | 279 +++++++++++++++ .../IsProgramPipeline.c | 113 ++++++ .../mix_pipeline_useprogram.c | 361 ++++++++++++++++++++ 7 files changed, 776 insertions(+) create mode 100644 tests/spec/arb_separate_shader_objects/CMakeLists.gl.txt create mode 100644 tests/spec/arb_separate_shader_objects/CMakeLists.txt create mode 100644 tests/spec/arb_separate_shader_objects/GetProgramPipelineiv.c create mode 100644 tests/spec/arb_separate_shader_objects/IsProgramPipeline.c create mode 100644 tests/spec/arb_separate_shader_objects/mix_pipeline_useprogram.c diff --git a/tests/all.tests b/tests/all.tests index 20120d1..2cbf3c4 100644 --- a/tests/all.tests +++ b/tests/all.tests @@ -1079,6 +1079,13 @@ add_concurrent_test(arb_occlusion_query, 'occlusion_query_meta_fragments') add_concurrent_test(arb_occlusion_query, 'occlusion_query_meta_no_fragments') add_concurrent_test(arb_occlusion_query, 'occlusion_query_order') +# Group ARB_separate_shader_objects +arb_separate_shader_objects = Group() +spec['ARB_separate_shader_objects'] = arb_separate_shader_objects +arb_separate_shader_objects['sso-GetProgramPipelineiv'] = concurrent_test('arb_separate_shader_object-GetProgramPipelineiv') +arb_separate_shader_objects['sso-IsProgramPipeline'] = concurrent_test('arb_separate_shader_object-IsProgramPipeline') +arb_separate_shader_objects['sso-mix_pipeline_useprogram'] = concurrent_test('arb_separate_shader_object-mix_pipeline_useprogram') + # Group ARB_sampler_objects arb_sampler_objects = Group() spec['ARB_sampler_objects'] = arb_sampler_objects diff --git a/tests/spec/CMakeLists.txt b/tests/spec/CMakeLists.txt index 18b1d37..97efd36 100644 --- a/tests/spec/CMakeLists.txt +++ b/tests/spec/CMakeLists.txt @@ -15,6 +15,7 @@ add_subdirectory (arb_robustness) add_subdirectory (arb_sampler_objects) add_subdirectory (arb_seamless_cube_map) add_subdirectory (amd_seamless_cubemap_per_texture) +add_subdirectory (arb_separate_shader_objects) add_subdirectory (arb_shader_texture_lod/execution) add_subdirectory (arb_shader_objects) add_subdirectory (arb_sync) diff --git a/tests/spec/arb_separate_shader_objects/CMakeLists.gl.txt b/tests/spec/arb_separate_shader_objects/CMakeLists.gl.txt new file mode 100644 index 0000000..e651956 --- /dev/null +++ b/tests/spec/arb_separate_shader_objects/CMakeLists.gl.txt @@ -0,0 +1,14 @@ +include_directories( + ${GLEXT_INCLUDE_DIR} + ${OPENGL_INCLUDE_PATH} +) + +link_libraries ( + piglitutil_${piglit_target_api} + ${OPENGL_gl_LIBRARY} + ${OPENGL_glu_LIBRARY} +) + +piglit_add_executable (arb_separate_shader_object-IsProgramPipeline IsProgramPipeline.c) +piglit_add_executable (arb_separate_shader_object-GetProgramPipelineiv GetProgramPipelineiv.c) +piglit_add_executable (arb_separate_shader_object-mix_pipeline_useprogram mix_pipeline_useprogram.c) diff --git a/tests/spec/arb_separate_shader_objects/CMakeLists.txt b/tests/spec/arb_separate_shader_objects/CMakeLists.txt new file mode 100644 index 0000000..144a306 --- /dev/null +++ b/tests/spec/arb_separate_shader_objects/CMakeLists.txt @@ -0,0 +1 @@ +piglit_include_target_api() diff --git a/tests/spec/arb_separate_shader_objects/GetProgramPipelineiv.c b/tests/spec/arb_separate_shader_objects/GetProgramPipelineiv.c new file mode 100644 index 0000000..81f6978 --- /dev/null +++ b/tests/spec/arb_separate_shader_objects/GetProgramPipelineiv.c @@ -0,0 +1,279 @@ +/* + * Copyright © 2013 Gregory Hainaut <gregory.hain...@gmail.com> + * + * 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.
