================ Comment at: include/clang/Basic/Builtins.def:480 BUILTIN(__builtin_thread_pointer, "v*", "nc") +BUILTIN(__builtin_launder, "v*v*", "nt") ---------------- GCC's is type-generic: ``` #include <type_traits> bool is_type_generic() { int v; return std::is_same<decltype(__builtin_launder(&v)), decltype(&v)>::value; } ``` However this `BUILTIN` line says that this one is not (yeah, I see it's being fixed up in Sema later in this patch). I think you need to use custom type checking here via `t`. https://reviews.llvm.org/D40218 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
