#define X(a) (a+1)
int main()
{
    return X(1);
}

Compiled with gcc -g3 I am able to evaluate the X() macro in gdb:

$ gcc -g3 x.c
$ gdb ./a.out
...
(gdb) b main
(gdb) r
(gdb) p X(1)
$1 = 2
(gdb)

Compiled with clang -g3, it behaves the same as -g: I don't get macro
information:
$ clang -g3 x.c
$ gdb ./a.out
...
(gdb) b main
(gdb) r
(gdb) p X(1)
No symbol "X" in current context.
