No, it can't be. Objective-C has its runtime method dispatch and
a message is equiverent to plain string. And I'm thinking about
more compact one.

Okey with this. And assigning arbitrary value to symbol_ref must
be able.

11.7 Constant Expression Types
==============================
...
`(const:M EXP)'
Represents a constant that is the result of an assembly-time
arithmetic computation. The operand, EXP, is an expression that
contains only constants (`const_int', `symbol_ref' and `label_ref'
expressions) combined with `plus' and `minus'. However, not all
combinations are valid, since the assembler cannot do arbitrary
arithmetic on relocatable symbols.
M should be `Pmode'.

By the way, maybe comdat is like,
---- foo.h -----
@linkonce (
int A=10;
int add_A {int x)
{
return x+A;
}
)
-----------------
---- file1.c ----
#incluide "foo.h"
-----------------
---- file2.c ----
#incluide "foo.h"
-----------------
---- file3.c ----
#incluide "foo.h"
