[Soot-list] Can soot analyze dacapo bench under IBM JVM in PPC architecture.

[Eric Bodden]

Hi Xinwei.

This could be due to multiple things:

- A bug in the runtime library for ppc.
- A bug in the JVM for ppc.
- A bug in Soot that only manifests itself when analyzing the runtime
library for ppc.

To figure out which source this error has, it may make sense to use
the same command line as you are using now, but run Soot on a
different VM. Right now you are running Soot on ppc and the ppc JVM,
and also use it to analyze the ppc runtime library. Howver, it should
be perfectly possible to run Soot on your other architecture (and VM)
but still pass in Soot's command line the very same ppc runtime
library, i.e.  /usr/lib/jvm/ibm-java-ppc64/jre/lib/ibmjcefw.jar:/usr/lib/jvm/ibm-java-ppc64/jre/lib/rt.jar.

If this still fails, then it's likely a bug in Soot. If not, then it's
likely a bug in the execution environment for ppc.
