--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Ok, I see the issue.
DSE is not removing:
_4 = (int) _10;
Which does not allow the removal of:
_10 = std::mersenne_twister_engine<long unsigned int, 32, 624, 397, 31,
2567483615, 11, 4294967295, 7, 2636928640, 15, 4022730752, 18,
1812433253>::operator() (&gen32);
Let me see if I can come up with a simple example.
