Consider this:
__attribute__((weak)) extern int const K = 7;
int f(void) { return K; }
int a[K];
Assuming the combination of 'weak' and 'const' is legitimate
(and it seems useful enough to allow), the compiler should avoid
the constant-promotion optimization when generating f(), and
should fault a[].
