More on using GHDL

The core need of any system software language is a pointer type. GHDL doesn't have this, only the VHPIDIRECT pure-function-call interface system. No big deal, though - we should be able to pass constrained integer types through to an assembly-language trampoline which will do the memory interfacing for us. IIRC, the new versions of gcc and binutils will optimize away the object-to-object calling indirection, eliminating the overhead normally associated with calling an API function outside of local object scope.
