ternary operator for clang's extended vectors

Question

I\'ve tried playing with clang\'s extended vectors. The ternary operator is supposed to work, but it is not working for me. Example:

int main()
{
  using int4 =          


        

Answer 1

This works in a pinch:

auto const diff = a-b;
auto const ra( - (diff!=zero) * a - (diff==zero) *b);

I guess this is a bug in the compiler, or in the documentation you linked.
