The concepts of "address" and "constant",
aren't mutually exclusive.

N869
6.6 Constant expressions

[#9] An address constant is a null pointer, a pointer to an
lvalue designating an object of static storage duration, or
to a function designator;

However, in the OPs case of wanting to disassemble, modify,
reassemble, it makes a big difference. Consider:

foo(&x);
bar(0x1234);

If &x==0x1234, it is quite possible to see this as a disassembly:

push 0x1234
call foo
push 0x1234
call bar
