Re: TR1 Math Special Functions


Hi Ed,

So, would it be better for me to put these __builtin_isnan (actually behind a function that wraps this) Or we could find all the functions wrapped in the C99_MATH guards for which we have such intrinsics and provide alternate implementations.

I think I'll start the former with a comment to replace it with just the std::isnan if/when we do the second option.

you are right in raising this issue, I had the same thought. I agree with you, better decouple the issues and first commit a "minimal" patch adding the new TR1 facilities. Then we can re-examine those builtins and figure out which ones are completely expanded and can directly implement the standard mandated classification macros in a very simple way.


Paolo.
