Hello, I built both version of jdk8 and jdk9 on my local system, and compares output of preprocessor and generated assemblers, both are identical. But jdk8u60 from RE actually 20% faster than my version of jdk8. It seems that the difference is in the compiler and/or in some compiler(gcc) options used by default.
