Will clang 4.0 support the new LLVM Exception Handleing instructions ?

LLVM support new eh instructions.(http://llvm.org/docs/ExceptionHandling.html#new-exception-handling-instructions) Clang still use the old landingpad inst to support the C++ exceptions. Do we have any plan to enable the support of the new exception instructions ?

Thank you.

Clang already supports the new C++ exception handling instructions, it uses
them exclusively to implement MSVC compatible exception handling. The
landingpad scheme is retained because it provides a degree of flexibility
(and thus optimization opportunities) which isn't available in the new
instructions.
