--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Variant which also is valid C:
#pragma omp declare target
int data[]={5};
#pragma omp end declare target
inline int foo(int idx) { return data[idx]; }
int main()
{
int i;
#pragma omp target map(to:i)
i = foo(0);
return i;
}
Result as follows; enclosing the 'foo' in the declare-target block has no
effect.
With g++ this still fails with:
bar2.cc:2:7: error: variable 'data' has been referenced in offloaded code but
hasn't been marked to be included in the offloaded code
2 | int data[]={5};
| ^
lto1: fatal error: errors during merging of translation units
But with cc it fails with:
unresolved symbol foo
mkoffload: fatal error: ...
