Let's call this HasMemoryCostMemberFunction.

Let's call these dummy.

Let's call this "template<typename T, bool hasMemoryCostMemberFunction = HasMemoryCostMemberFunction<T>::value> struct ReportMemoryCost".

> Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:2720
> +    static void reportExtraCost(ExecState* exec, T* impl)

Let's call this reportMemoryCost.

Unfortunately it would seem that another build failure was masking this one, or something along those lines:

http://build.webkit.org/builders/Apple%20Win%20Release%20%28Build%29/builds/47641/steps/compile-webkit/logs/stdio

Any idea how to fix it?

I've tried a clean build, also curious that one bot (The opensource debug builder) seems to be okay with the change...

The bot seems to be trying to share the definition of ReportMemoryCost between different JS bindings files, has someone decided to allinonefile them?
