--- Comment #9 from Patrick Palka <ppalka at gcc dot gnu.org> ---
> When r14-205 fixed that, the total number of loop iterations increased by approximately 4x (2x due to symmetry with unsigned, 2x due to the loop range being -limit...limit instead of 0...limit) which is roughly consistent with a 5x increase in test execution time.
Oops, the increase is more like 5x due to loop nesting. So the signed_p case
performs 4x more iterations than the unsigned case, and previously the signed_p
case was dead.
