--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Before that rev we had

int a = (int) (((((unsigned int) ll - (unsigned int) ci) - (unsigned int) i) +
((((unsigned int) ci - (unsigned int) ll) + (unsigned int) i) - (unsigned int)
ci)) + 2270794745);

and now just

int a = -2024172551(OVF) - (int) ci;
