-From: Benjamin Barenblat <bbaren@google.com>
-Subject: Work around broken std::hash on s390x
-Forwarded: no
-Bug-Debian: https://bugs.debian.org/977638
-
-On s390x, std::hash hashes large classes of data to the same value, which
-violates assumptions made by the Abseil tests. #ifdef out the test code that
-depends on those assumptions.
