-From: Benjamin Barenblat <bbaren@google.com>
-Subject: Skip floating-point edge-case tests when using an x87
-Forwarded: yes
-Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/311bbd2e50ea35e921a08186840d3b6ca279e880
-
-32-bit Intel CPUs use 80-bit floats for intermediate values, which can
-change the results of floating point computations from what we normally
-expect. Identify tests that are sensitive to the x87, and skip them when
-we’re on 32-bit Intel.
-
-The author works at Google. Upstream applied this patch as Piper
-revision 378722613 and exported it to GitHub; the Applied-Upstream URL
-above points to the exported commit.
