Returning vectors by value

Clang Frontend
1

Hi all,

We would like to be able to add support to CLang for returning vectors
by value so you could do something like:

int2 my_func(int x)
{
   return (int2)(x,x);
}

main()
{
   printf("%d", my_func(5).x);
}

Obviously this is a completely pointless example but it demonstrates
what we would like to be able to do. At the moment we hit an assert in
EmitCallExprLValue: "Can't have a scalar return unless the return type
is a reference type!"

I was wondering if anyone had any advice about the right way to go about
solving this?

Thanks for your help,

Rob

this is just a missing case in the code generator, please file a bugzilla.
