Custom IndexTypes are passed to mdspan related objects in one of two ways: * as a template parameter pack, * or as an array/span. These two cases have different requirements on the (constness of) custom IndexTypes. Therefore, the tests are restructured as follows: * allow testing with different custom integers, * separate code that tests the two cases described above, * use int_like.h for all tests with custom integers. The affected tests are for: * creating extents, layout_stride::mapping and mdspan from custom integers, * mapping::operator() and mdspan::operator[]. PR libstdc++/121061 libstdc++-v3/ChangeLog: * testsuite/23_containers/mdspan/extents/custom_integer.cc: Enable checking with different custom integers. Improve checking non-existence of overloads for incompatible custom integers. * testsuite/23_containers/mdspan/layouts/mapping.cc: ditto. Also improve reuse of int_like.h. * testsuite/23_containers/mdspan/layouts/stride.cc: ditto. * testsuite/23_containers/mdspan/mdspan.cc: ditto. * testsuite/23_containers/mdspan/extents/int_like.h: Rename (old name). * testsuite/23_containers/mdspan/int_like.h: Rename (new name). (ThrowingInt): Add. (NotIntLike): Add. Reviewed-by: Jonathan Wakely <jwak...@redhat.com> Reviewed-by: Tomasz KamiÅski <tkami...@redhat.com> Signed-off-by: Luc Grosheintz <luc.groshei...@gmail.com>
