An example which I came up when looking at PR 2692:
(Note that more opportunities for this comes up after my casting pass is installed)
struct dcomplex
{
dcomplex(double =0.0, double =0.0);
dcomplex& operator*=(const dcomplex&);
typedef __complex__ double _ComplexT;
_ComplexT _M_value;
dcomplex(_ComplexT __z) : _M_value(__z) { }
};
inline dcomplex
operator*(const dcomplex& __x, const dcomplex& __y)
{ return dcomplex (__x) *= __y; }
inline
dcomplex::dcomplex(double __r, double __i)
{
__real__ _M_value = __r;
__imag__ _M_value = __i;
}
inline dcomplex&
dcomplex::operator*=(const dcomplex& __z)
{
_ComplexT __t;
__real__ __t = __real__ __z._M_value;
__imag__ __t = __imag__ __z._M_value;
_M_value *= __t;
return *this;
}
typedef dcomplex Complex8;
Complex8 m;
Complex8 g;
void determinant()
{
Complex8 _m = m;
Complex8 t = _m * _m;
g = t;
}

------- Additional Comments From pinskia at gcc dot gnu dot org 2004-07-09 07:36 -------
Fixed by RTH's rewrite to SRA.
_m$_M_value$imag = IMAGPART_EXPR <m._M_value>;
_m$_M_value$real = REALPART_EXPR <m._M_value>;
IMAGPART_EXPR <g._M_value> = _m$_M_value$imag * _m$_M_value$real * 2.0e+0;
REALPART_EXPR <g._M_value> = _m$_M_value$real * _m$_M_value$real - _m$_M_value$imag * _m$
_M_value$imag;
return;
