What is the correct way to invoke a delegate from inline assembler?  Also, where does the this pointer go when I am calling a function in an object?

In C++ the following would work,

mov ECX, [object pointer];
// Push arguments
call class_method;

But in D, I'm not so sure what is going on.  It seems like EAX gets the pointer in most cases, but I can't be certain that this is always true.  It is possible that it is just another parameter, in which case is it the first or the last? Also, I'm not positive on the memory layout of the delegate object.

Any info at all would be much appreciated.
