--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Minor postscript: While the following (reduced testcase in comment 0) looks a
bit odd,
int data;
...
#pragma acc data copyin(a, a.data)
the original uses a pointer. Thus, something like
int *data;
...
#pragma acc data copyin(a, a.data[0:n])
which is more sensible. This variant still gives an ICE.
However, either variant shouldn't ICE
BTW: GCC 12 has the following omplower dump for this variant:
#pragma omp target oacc_data \
map(to:a [len: 8]) map(alloc:a.data [len: 8]) \
map(to:*_8 [len: _7]) map(attach:a.data [bias: 0])
--------------------------------------
long long n = 10;
class data_container {
public:
int *data;
};
void test2() {
data_container a;
a.data = (int*)__builtin_malloc (n * sizeof (int));
#pragma acc data copyin(a, a.data[0:n])
{ }
}
