Sure, there's one static (local):
$ cat /tmp/ifunc.c
static volatile int a;
static int my_foo1 (void) { return 1; }
static int my_foo2 (void) { return 2; }
typedef int (*F) (void);
static F resolve_foo (void) { if (a) return my_foo1; else return my_foo2; }
static int foo (void) __attribute__ ((ifunc ("resolve_foo")));
int
main ()
{
if (foo () != 2)
__builtin_abort ();
}
Commenting static before 'int foo' you get a global one.
