Annoyingly the stdout and stderr seem to be interleaved, but it's better than nothing.
With SSE disabled, the default tolerance of EXPECT_FLOAT_EQ was too tight for some tests to pass. (The non-SSE results are probably actually closer to the true value; the difference probably arises from using 80-bit-precision x87 operations). The expected value was set by just running the code and seeing what it output. Independent of compiler or OS, the x87-based results appear to form a separate cluster from the SSE ones. Also test the plane returned by the trace in a couple tests.
