A destroying operator delete takes responsibility for calling the destructor for the object it is deleting; this is intended to be useful for sized delete of a class allocated with a trailing buffer, where the compiler can't know the size of the allocation, and so would pass the wrong size to the non-destroying sized operator delete. gcc/c-family/ * c-cppbuiltin.c (c_cpp_builtins): Define __cpp_impl_destroying_delete. gcc/cp/ * call.c (std_destroying_delete_t_p, destroying_delete_p): New. (aligned_deallocation_fn_p, usual_deallocation_fn_p): Use destroying_delete_p. (build_op_delete_call): Handle destroying delete. * decl2.c (coerce_delete_type): Handle destroying delete. * init.c (build_delete): Don't call dtor with destroying delete. * optimize.c (build_delete_destructor_body): Likewise. libstdc++-v3/ * libsupc++/new (std::destroying_delete_t): New.
