Interesting. I'd have thought that calling __assume(0) was useless, but it tells the optimizer that the else clause won't occur. I wonder if that will work at all or as well as BOOST_ASSERT(e); __assume(e);
It's not useless, see my previous posts in the thread for examples of code generated with and without __assume(0).
I said "I would have thought [it] was useless." However, I consulted the documentation and found that it was useful. That's why I said it was "interesting." -- Rob Stewart stewart@sig.com Software Engineer http://www.sig.com Susquehanna International Group, LLP using std::disclaimer;
