Re: [RFA]: gdbarch FETCH_POINTER_ARGUMENT

Adam,

I need to think about FETCH_POINTER_ARGUMENT.  It needs additional 
parameters - something to that lets it fetch registers or memory, and 
something identifying the type of pointer.

As for convert function pointer, I think, at this stage, it would be 
better to simply eliminate the only call:

@@ -1894,7 +1840,7 @@ find_implementation_from_class (CORE_ADD
  #endif

  	      if (meth_str.name == sel)
-		return CONVERT_FUNCPTR (meth_str.imp);
+		return CONVERT_FUNCTION_POINTER (meth_str.imp);
  	    }
  	  mlistnum++;
  	}

replacing it with the code from the default case (do nothing), and a 
comment mentioning that HP was doing a pointer dereference here. I think 
it is better to leave this one to someone that can both demonstrate the 
need for the tweek, and that some other existing method/code isn't 
sufficient (I think I've seen this before).
