--- Comment #2 from Michael Meissner <meissner at gcc dot gnu.org> ---
It is a real bug in the PowerPC backend.
The bug is that the unsigned int value of 0x80000000 is converted incorrectly,
when it is converted from unsigned int to __float128 and back to unsigned int.
I have a solution already as part of PRs target/79038, target/79202, and
target/79203.
Most of the work in those bugs is an enhancement that did not make the stage3
cut, but I will try to isolate a minimum patch to fix GCC 7.
