<pre>
    It seems there are missing _NOEXCEPT specifiers on certain functions.   For example the first:
void deallocate function in ___memory/allocator.h has _NOEXCEPT, but the second does not. 
Also, the functions called by these routines (for example __libcpp_deallocate in the header file new)  and the functions called by those routines should also be _NOEXCEPT.

This is somewhat important because when a noexcept function calls another function that is not noexcept, it must create a handler in case that called function throws an exception.   Adding _NOEXCEPT in the correct place will improve code generation for these routines.

Certainly not a significant issue....

Thank you for your time,
