/**
* The tests in ../Math/Log1pTests.java test properties that should
* hold for any log1p implementation, including the FDLIBM-based one
* required for StrictMath.log1p. Therefore, the test cases in
* ../Math/Log1pTests.java are run against both the Math and
* StrictMath versions of log1p. The role of this test is to verify
* that the FDLIBM log1p algorithm is being used by running golden
* file tests on values that may vary from one conforming log1p
* implementation to another.
