I agree. We the GCC team have to accept that some CPUs may not have the ability to do this. That might be old x86 CPUs; it might also be brand-new embedded CPUs. Obviously, distributors can do whatever they please, but the C++ run-time library needs to tolerate CPUs without this feature. It can of course offer reduced functionality (at compile-time or at run-time) on CPUs without the necessary support. -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] (650) 331-3385 x713
