From 38c63abf09eaab9e2023d86b918784cd25cc0bc5 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 22 Jan 2016 13:07:10 -0500 Subject: [PATCH] glsl: add GL_OES_geometry_point_size and conditionalize gl_PointSize For now this will be enabled in tandem with GL_OES_geometry_shader. Should a driver come along that wants to separate them out, another enable can be added. Also adds the missed GL_OES_geometry_shader define in glcpp. Signed-off-by: Ilia Mirkin Reviewed-by: Marta Lofstedt --- src/compiler/glsl/builtin_variables.cpp | 7 ++++++- src/compiler/glsl/glcpp/glcpp-parse.y | 7 +++++++ src/compiler/glsl/glsl_parser_extras.cpp | 1 + src/compiler/glsl/glsl_parser_extras.h | 2 ++ src/mesa/main/extensions_table.h | 1 + 5 files changed, 17 insertions(+), 1 deletion(-) diff --git a/src/compiler/glsl/builtin_variables.cpp b/src/compiler/glsl/builtin_variables.cpp index ccc04c0..25d92cc 100644 --- a/src/compiler/glsl/builtin_variables.cpp +++ b/src/compiler/glsl/builtin_variables.cpp @@ -1201,7 +1201,12 @@ builtin_variable_generator::generate_varyings() /* gl_Position and gl_PointSize are not visible from fragment shaders. */ if (state->stage != MESA_SHADER_FRAGMENT) { add_varying(VARYING_SLOT_POS, vec4_t, "gl_Position"); - add_varying(VARYING_SLOT_PSIZ, float_t, "gl_PointSize"); + if (!state->es_shader || + state->stage == MESA_SHADER_VERTEX || + (state->stage == MESA_SHADER_GEOMETRY && + state->OES_geometry_point_size_enable)) { + add_varying(VARYING_SLOT_PSIZ, float_t, "gl_PointSize"); + } } if (state->is_version(130, 0)) { diff --git a/src/compiler/glsl/glcpp/glcpp-parse.y b/src/compiler/glsl/glcpp/glcpp-parse.y index ef1a657..43a1aa94 100644 --- a/src/compiler/glsl/glcpp/glcpp-parse.y +++ b/src/compiler/glsl/glcpp/glcpp-parse.y @@ -2386,6 +2386,13 @@ _glcpp_parser_handle_version_declaration(glcpp_parser_t *parser, intmax_t versio add_builtin_define(parser, "GL_OES_texture_storage_multisample_2d_array", 1); if (extensions->ARB_blend_func_extended) add_builtin_define(parser, "GL_EXT_blend_func_extended", 1); + + if (version >= 310) { + if (extensions->OES_geometry_shader) { + add_builtin_define(parser, "GL_OES_geometry_point_size", 1); + add_builtin_define(parser, "GL_OES_geometry_shader", 1); + } + } } } else { add_builtin_define(parser, "GL_ARB_draw_buffers", 1); diff --git a/src/compiler/glsl/glsl_parser_extras.cpp b/src/compiler/glsl/glsl_parser_extras.cpp index 6038954..7dad466 100644 --- a/src/compiler/glsl/glsl_parser_extras.cpp +++ b/src/compiler/glsl/glsl_parser_extras.cpp @@ -598,6 +598,7 @@ static const _mesa_glsl_extension _mesa_glsl_supported_extensions[] = { /* OES extensions go here, sorted alphabetically. */ EXT(OES_EGL_image_external, false, true, OES_EGL_image_external), + EXT(OES_geometry_point_size, false, true, OES_geometry_shader), EXT(OES_geometry_shader, false, true, OES_geometry_shader), EXT(OES_standard_derivatives, false, true, OES_standard_derivatives), EXT(OES_texture_3D, false, true, dummy_true), diff --git a/src/compiler/glsl/glsl_parser_extras.h b/src/compiler/glsl/glsl_parser_extras.h index 3f88e01..a905b56 100644 --- a/src/compiler/glsl/glsl_parser_extras.h +++ b/src/compiler/glsl/glsl_parser_extras.h @@ -591,6 +591,8 @@ struct _mesa_glsl_parse_state { */ bool OES_EGL_image_external_enable; bool OES_EGL_image_external_warn; + bool OES_geometry_point_size_enable; + bool OES_geometry_point_size_warn; bool OES_geometry_shader_enable; bool OES_geometry_shader_warn; bool OES_standard_derivatives_enable; diff --git a/src/mesa/main/extensions_table.h b/src/mesa/main/extensions_table.h index 11f4482..ad5dc60 100644 --- a/src/mesa/main/extensions_table.h +++ b/src/mesa/main/extensions_table.h @@ -311,6 +311,7 @@ EXT(OES_element_index_uint , dummy_true EXT(OES_fbo_render_mipmap , dummy_true , x , x , ES1, ES2, 2005) EXT(OES_fixed_point , dummy_true , x , x , ES1, x , 2002) EXT(OES_framebuffer_object , dummy_true , x , x , ES1, x , 2005) +EXT(OES_geometry_point_size , OES_geometry_shader , x , x , x , 31, 2015) EXT(OES_geometry_shader , OES_geometry_shader , x , x , x , 31, 2015) EXT(OES_get_program_binary , dummy_true , x , x , x , ES2, 2008) EXT(OES_mapbuffer , dummy_true , x , x , ES1, ES2, 2005) -- 2.7.4
