I can understand that, but it is nice to know exactly what is missing
so we have a chance to get there eventually. __builtin_sqrt is a good
example indeed. I thought masking was supposed to work (depending on
what that means), although possibly only in C.
Marc, I think it would be very nice to have a record of these missing
features / weaknesses of the vector extensions. Since you know the
extensions pretty well by now, could you please double check whether
something is missing from Bugzilla, possibly open a metabug, something
like that?
Thanks!
Paolo.
