It's returning random values, because RESOURCE_VAR() is casting different objects into ir_variable pointers.
This updates _mesa_count_active_attribs to filters the resources with the same logic used in _mesa_longest_attribute_name_length. https://bugs.freedesktop.org/show_bug.cgi?id=90207 P.S.: RESOURCE_VAR cast helper should have assertions to catch this. --- src/mesa/main/shader_query.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/mesa/main/shader_query.cpp b/src/mesa/main/shader_query.cpp index a84ec84..d2ca49b 100644 --- a/src/mesa/main/shader_query.cpp +++ b/src/mesa/main/shader_query.cpp @@ -302,8 +302,10 @@ _mesa_count_active_attribs(struct gl_shader_program *shProg) 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++; + if (res->Type == GL_PROGRAM_INPUT && + res->StageReferences & (1 << MESA_SHADER_VERTEX) && + is_active_attrib(RESOURCE_VAR(res))) + count++; } return count; } -- 2.1.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
