http://en.wikipedia.org/wiki/Harvard_architecture lists a number.

However, any POSIX system requires function pointers to be no larger
than data pointers so that the dlsym() function can work.

Itanium natively requires functions to be identified by a 64-bit
instruction pointer plus a 64-bit global data pointer.  The ABI defines
function pointers to point to these 128-bit data structures.
