Processor: The port supports only 64-bit PPC machines. It recognizes Power chips 5 through 8 and generates code optimized for these processors. It lacks an instruction scheduler targeted to Power 6, which is an in-order issueing processor.
Status (see also the main page of the port):
With the end of the main line support of jdk10 and jdk9 we also stopped supporting jdk 9 and 10. For further development of jdk 11 and later see the main page of the port.
In March 2018 JDK 10 was release on the three platforms.
In September 2017 JDK 9 was released on the three platforms.
