The issue we're running into when running CTS is that glsl types are deleted while builtins depending on them are not. This happens because on one hand we have glsl types ref counted, but builtins are not. Instead builtins are destroyed when unloading libGL or explicitly calling glReleaseShaderCompiler(). This change removes almost entirely any dealing with glsl types ref/unref by letting the builtins deal with it instead. In turn we introduce a builtin ref count mechanism. Each GL context takes a reference on the builtins when compiling a shader for the first time. It releases the reference when the context is destroyed. It can also explicitly release those when glReleaseShaderCompiler() is called. Finally we also take a reference on the glsl types when loading libGL to avoid recreating glsl types too often. v2: Ensure we take a reference if we don't have one in link step (Lionel) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110796 Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Tapani Pälli <tapani.palli@intel.com>
