--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Sorry, wrong test case. Here's the right one:
const char a[] = "abc";
const char* const s = "abc";
void global_array (void)
{
if (__builtin_strlen (a) != 3)
__builtin_abort ();
}
void local_array (void)
{
static const char a[] = "abc";
if (__builtin_strlen (a) != 3)
__builtin_abort ();
}
void global_pointer (void)
{
if (__builtin_strlen (s) != 3)
__builtin_abort ();
}
void local_pointer (void)
{
static const char* const s = "abc";
if (__builtin_strlen (s) != 3)
__builtin_abort ();
}
struct X { char a [4]; };
const struct X x = { "abc" };
void global_struct (void)
{
if (__builtin_strlen (x.a) != 3)
__builtin_abort ();
}
void local_struct (void)
{
static const struct X x = { "abc" };
if (__builtin_strlen (x.a) != 3)
__builtin_abort ();
}
