<div>
<pre>Code like:
double _Complex mul_double_cc(double _Complex a, double _Complex b) {
return a * b;
}
will result in a declaration of __muldc3 or similar. On architectures that
don't pass the complex via registers, this declaration looks e.g. like:
declare void @__muldc3({ double, double }*, double, double, double, double)
This is missing the sret attribute on the first argument.</pre>
