  10. Only run the irel checks if the libc function is found 

    This just saves a bit of unneeded computation.

  18. Use C-style strings for symbol names 

    There's no need to have a std::string object that incurs the overhead of a constructor/destructor call to just hold a literal that's only visible in the current translation unit.

  19. Use an anonymous namespace instead of 'static' for symbol names 

    It's the C++ way.
