[Bug optimization/14729] New: [tree-ssa] missed semi high abstraction penalty due to casts

[pinskia at gcc dot gnu dot org]

Derived from <http://gcc.gnu.org/ml/gcc/2004-03/msg01314.html>.
struct OOf {
        float value;
        OOf() {value = 0.0;}
};
inline OOf operator+(OOf op1, OOf op2)
{
        OOf f;
        f.value = op1.value + op2.value;
        return f;
}
inline OOf operator*(OOf op1, OOf op2)
{
        OOf f;
        f.value = op1.value * op2.value;
        return f;
}
inline OOf operator-(OOf op1, OOf op2)
{
        OOf f;
        f.value = op1.value - op2.value;
        return f;
}
OOf test_func(
        OOf a,
        OOf b,
        OOf c
)
{
        OOf d, e;
        OOf result;
        d = a * b + b * c;
        e = a * c - b * d;
        result = d * e;
        return result;
}

I also have a patch to fix this one too.
