Also, since this function returns void, there's no way for it to notify the caller of failure. A similar comment applies to all of the other serialize*() functions in this patch. (Of course, considering our previous discussion about potentially removing these int return values, this issue may be moot).<br>

+serialize_glsl_type(const glsl_type *type, memory_writer &mem)<br></blockquote><div><br></div><div>The last time I reviewed this series, I mentioned the idea of making a hashtable that maps each glsl_type to a small integer, so that we could serialize each type just once (see <a href="http://lists.freedesktop.org/archives/mesa-dev/2013-November/047740.html" target="_blank">http://lists.freedesktop.org/archives/mesa-dev/2013-November/047740.html</a>). At the time, it sounded like you liked that idea. Have you made that change? It looks to me like you've stopped serializing the built-in types, but user-defined types are still serialized each time they occur.<br>
