The new revision does that: http://cr.openjdk.java.net/~asmundak/8073139/hotspot/webrev.03 http://cr.openjdk.java.net/~asmundak/8073139/jdk/webrev.03 http://cr.openjdk.java.net/~asmundak/8073139/root/webrev.03/

This has grown a lot from my version.

The main change seems to be in having to handle a ppc64le define in numerous places, which seems unnecessary as ppc64 is present there. The version I'm looking at that we used in 8 deliberately avoids this by forcing ARCH back to ppc64 on ppc64le. Was there a reason not to do that?

The only case where ppc64le is different to ppc64, the ABI is used:

-#if defined(__ia64) || defined(powerpc) +#if defined(__ia64) || (defined(powerpc) && !defined(ABI_ELFv2))
