The 32000 series does give you the option of doing this.  It's superficially
attractive, but not only does it cause problems with debuggers etc., it's
also pretty slow.  Unless you are doing something like dynamic linking where
you *must* resolve the name->address mapping at runtime, it's a loss.  There
are other machines, alas, where you don't get a choice.
