The tests for the SIMD floating-point maximum and minimum operations require particular care because the handling of the NaN values is non-deterministic and may vary between platforms. There is no way to match several NaN values in a test, so the solution is to extract the non-deterministic test cases into a separate file that is subsequently replicated for every backend under test, with adjustments made to the expected results.
