/* Closures represent a pair consisting of a function pointer, and
some user data. A closure is invoked by reinterpreting the closure
as a function pointer, and branching to it. Thus we can make an
interpreted function callable as a C function: We turn the
interpreter itself, together with a pointer specifying the
interpreted procedure, into a closure.
For IA64, function pointer are already pairs consisting of a code
pointer, and a gp pointer. The latter is needed to access global
variables. Here we set up such a pair as the first two words of
the closure (in the "trampoline" area), but we replace the gp
pointer with a pointer to the closure itself. We also add the real
gp pointer to the closure. This allows the function entry code to
both retrieve the user data, and to restire the correct gp pointer. */
