Subject: PATCH 2/2: New PPC64 class files (and updates to generic files) to support linux/ppc64 Hotspot SA wi
From: Maynard Johnson <maynardj () us ! ibm ! com>

[Download RAW message or body]
This patch adds PPC64 implementations of various class files needed to support
the Hotspot serviceability agent, most of which involves mirroring the VM's stack
for the jstack tool. The patch also makes some minor updates to several
architecture-independent class files to enable ppc64 support.
Going along with what appears to be tradition, the new PPC64 files have the
Oracle copyright statement instead of an IBM copyright, since much of the code in
these files was copied over from the x86 versions.
