Supported operating systems and processor implementations

AIX: The port supports AIX 5AIX 6.3 1 and later. It is tested to be built with xlC 12.  Patch level 12.01.0000.0008 or higher is required. We do not support iSeries PASE.

Linux ppc64: We build and run the VM on SLES 11.3 with gcc 4.3.48, but support it on other Linux distributions, too. Up to jdk8u update 112 we built on SLES 10.3 with gcc 4.1.2.

Linux ppc64le: We build and run the VM on SLES 12.1 Linux ppc64le: The little-endian Linux variants must be built with gcc 4.8.  We build it on SLES 12.1, but support it on other Linux distributions, too.

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.
