From a563689a408b7a28c710fb0e382272a0d823f38a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tapani=20P=C3=A4lli?= Date: Thu, 23 Apr 2015 11:13:17 +0300 Subject: [PATCH] mesa: refactor active attrib queries for glGetProgramiv MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Main motivation here is to get rid of iterating IR and encapsulate queries within program resources. No functional changes. Piglit tests calling the modified functionality: - gl-get-active-attrib-returns-all-inputs - glsl-1.50-get-active-attrib-array - getactiveattrib Signed-off-by: Tapani Pälli Reviewed-by: Martin Peres --- src/mesa/main/shader_query.cpp | 39 ++++++++++++++------------------------- 1 file changed, 14 insertions(+), 25 deletions(-) diff --git a/src/mesa/main/shader_query.cpp b/src/mesa/main/shader_query.cpp index bc6fec5..a84ec84 100644 --- a/src/mesa/main/shader_query.cpp +++ b/src/mesa/main/shader_query.cpp @@ -291,7 +291,6 @@ _mesa_GetAttribLocation(GLhandleARB program, const GLcharARB * name) return (loc >= 0) ? loc : -1; } - unsigned _mesa_count_active_attribs(struct gl_shader_program *shProg) { @@ -300,19 +299,13 @@ _mesa_count_active_attribs(struct gl_shader_program *shProg) return 0; } - exec_list *const ir = shProg->_LinkedShaders[MESA_SHADER_VERTEX]->ir; - unsigned i = 0; - - foreach_in_list(ir_instruction, node, ir) { - const ir_variable *const var = node->as_variable(); - - if (!is_active_attrib(var)) - continue; - - i++; + struct gl_program_resource *res = shProg->ProgramResourceList; + unsigned count = 0; + for (unsigned j = 0; j < shProg->NumProgramResourceList; j++, res++) { + if (is_active_attrib(RESOURCE_VAR(res))) + count++; } - - return i; + return count; } @@ -324,20 +317,16 @@ _mesa_longest_attribute_name_length(struct gl_shader_program *shProg) return 0; } - exec_list *const ir = shProg->_LinkedShaders[MESA_SHADER_VERTEX]->ir; + struct gl_program_resource *res = shProg->ProgramResourceList; size_t longest = 0; + for (unsigned j = 0; j < shProg->NumProgramResourceList; j++, res++) { + if (res->Type == GL_PROGRAM_INPUT && + res->StageReferences & (1 << MESA_SHADER_VERTEX)) { - foreach_in_list(ir_instruction, node, ir) { - const ir_variable *const var = node->as_variable(); - - if (var == NULL - || var->data.mode != ir_var_shader_in - || var->data.location == -1) - continue; - - const size_t len = strlen(var->name); - if (len >= longest) - longest = len + 1; + const size_t length = strlen(RESOURCE_VAR(res)->name); + if (length >= longest) + longest = length + 1; + } } return longest; -- 2.7.4
