            Bug ID: 106828
           Summary: cc1plus: warning: '-fsanitize=address' not supported

I just checked even the libasan.so and libubsan.so do exist. Also
-fsanitize=undefined works but -fsanitize=address does not work for loongarch.

Need a fix

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The fix is to define the target hook for Asan address.
