--- Comment #8 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Previously, in PR 86999 I pointed out to the reporter that it was okay for gcc
to turn a vector constructor with negative zeros to a trivial
all-positive-zeros constructor under -fno-signed-zeros, and nobody contradicted
me at the time.
I think the documentation needs to be clarified if that's not the intent, right
now I cannot for sure deduce from the manual what exactly the optimizations may
or may not do when constant propagation or such produces a "negative zero"
value.
