--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Fixed #c11 testcase:
template <typename T>
struct S {
T x;
int y;
};
template <typename T>
T
bar (T x)
{
return x;
}
void
foo (int x, int y)
{
auto b = [&] { return x; };
S <decltype (b)> c = { b, 42 };
S <decltype (b)> d[2] = { { b, 42 }, { b, 42 } };
auto *p = &d[1];
#pragma omp target
if (c.x () != 42 || d[y].x () != 42 || bar (p)->x () != 42)
__builtin_abort ();
}
int
main ()
{
foo (42, 0);
}
We ICE on this, in particular the bar (p)->x () part, while somehow handle
(unsure if correctly) the other cases.
So supposedly the short term workaround could simply handle the
COMPONENT_REFs/ARRAY_REFs around a var which is non-local and that is it for
now. Even that will misbehave, e.g. if ARRAY_REF index is something defined
inside of the target region or not firstprivatized like here (say bar (y) as an
example or int z = y; d[z].x ()).
