--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Thu May 23 15:08:58 2019 New Revision: 271565 URL: https://gcc.gnu.org/viewcvs?rev=271565&root=gcc&view=rev Log: PR libstdc++/90220 Fix any_cast for non-object types Backport from mainline 2019-04-24 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/90220 (partial) * include/std/any (any_cast<T>(any*), any_cast<T>(const any*)): Do not attempt ill-formed static_cast to pointers to non-object types. * testsuite/20_util/any/misc/any_cast.cc: Test std::any_cast with function types. Backport from mainline 2019-04-24 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/90220 * include/std/any (__any_caster): Use remove_cv_t instead of decay_t. Avoid a runtime check for types that can never be stored in std::any. * testsuite/20_util/any/misc/any_cast.cc: Test std::any_cast with array types. Backport from mainline 2019-05-23 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/90220 * include/experimental/any (__any_caster): Constrain to only be callable for object types. Use remove_cv_t instead of decay_t. If the type decays or isn't copy constructible, compare the manager function to a dummy specialization. (__any_caster): Add overload constrained for non-object types. (any::_Manager_internal<_Op>): Add dummy specialization. * testsuite/experimental/any/misc/any_cast.cc: Test function types and array types.
