I do see generated code for the explicitely instantiated operator. sth like void foo(ab<float> *a, ab<long double> *b){ c::f<ab<float> *, ab<long double> *> (a,b); } void bar(ab<float> x) { ab<__float128> a(x); } should instantiate both functions below explicitely but __float128 (taken from the demangling) doesn't do it and using 'long double' ends up with a different mangling (and code). That said, cross and native shouldn't differ and tracking down the reason would be interesting.
