See <http://llvm.org/docs/LangRef.html#t_function> and look at the second example:

	float (i16 signext, i32 *) *

	Pointer to a function that takes an i16 that should be sign extended
	and a pointer to i32, returning float.

Hence, my confusion over the issue.  If parameter attributes aren't included in function types, then I'd like to know how to call a function through a pointer of the type in the example above.  I must be failing still to comprehend an important concept in the language.
