gdb.texinfo?  Do we need a gdb.base/harvard.exp?

I can imagine that.  I was kind of assuming you're examples would be 
pre/post all changes.

then

to be 110% sure, all of:

	(gdb) print main
	(gdb) print &main
	(gdb) print/x main
	(gdb) print/x &main

end up displaying the same hex (CORE_ADDR) value?
