Hi David,Hi Deepak,
The primary change here is a build change so I've cc'ed build-dev. The majority of the changes are to JVMTI demo files hence I've cc'd serviceability-dev. I think JDK8-dev doesn't need to be included now so I've bcc'd it. While gcc compilation on sparc is rare I'm not sure that simply deleting the sparc-only option unconditionally is the right thing to do.
I thought about that too. But I was unable to find info on OpenJDK + SPARC + Linux. Is that combination even supported? The README doesn't list it: http://hg.openjdk.java.net/jdk6/jdk6/raw-file/tip/README-builds.html#MBE
The option seemed more like a relic from Solaris + SPARC config rather than a requirement for Linux + SPARC.
Cheers, Deepak
David
