This patch implements built-in trait for std::add_pointer.
gcc/cp/ChangeLog:
* cp-trait.def: Define __add_pointer.
* semantics.cc (finish_trait_type): Handle CPTK_ADD_POINTER.
gcc/testsuite/ChangeLog:
* g++.dg/ext/has-builtin-1.C: Test existence of __add_pointer.
* g++.dg/ext/add_pointer.C: New test.
