I just ran into the issue that `#pragma omp simd` does not work on C++ iterator loops (godbolt). From going through the specifications I understand that this restriction was part of 4.5 and 5.0, but was dropped with 5.1.
I assume that it is about "non-pointer random access iterators" – as the subject line states.
In OpenMP 5.0, there is: "2.9.1 Canonical Loop Form": "In the simd construct the only random access iterator types that are allowed for var are pointer types." [OpenMP 5.0, 100:15-16] But I still see in OpenMP 5.1: "2.11.5.1 simd Construct": "Restrictions to the simd construct are as follows: ... [C++] The only random access iterator types that are allowed for the associated loops are pointer types." [OpenMP 5.1, 137:2, 137:22]. Same words as in 5.1 are also in OpenMP 5.2 in "10.4 simd Construct" [235:31]. Did I miss something? If so, can you provide the example?
