[Bug tree-optimization/44632] [4.4/4.5/4.6 regression] wrong code for complex division

Btw, does this only happen at -O0?  If you adjust the testcase like

#include <complex>
#include <iostream>

void __attribute__((noinline))
g(std::complex<double> x)
{
  std::cout << x << std::endl;
}

void __attribute__((noinline))
f(std::complex<double> x)
{
  g (x);
  x = 1.0 / x;
  g (x);
}

int main()
{
  f(2.0);
}
