To improve the "fingerprinting" coverage of the StrictMath tests, I've added test cases where the worst-case of a non-FDLIBM library is larger than the FDLIBM worst-case. Assuming reasonable methodology of the paper, the output of the other math library must differ from FDLIBM at such a point. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15879#issuecomment-1963421766
