First I tried it on Soot trunk but I got a lot of resolving errors
that I don't know the meaning of (and the wiki page mentioned in the
SVN logs seems unaccessible). I'll check this one with Ondrej later.
My own branch isn't really suitable being in flux, but I tested Soot
2.1.0 with the patch I gave you. This is the output I got:
[navindra@string ~/soot/tmp/guillaume] java -Xmx400m Main Foo

======================================= Finished freshness analysis
Transforming Foo...
Writing to sootOutput/Foo.shimple
Soot finished on Tue Sep 21 13:47:07 EDT 2004
Soot has run for 2 min. 29 sec.
How does this look? As far as I can tell it is working.
Just in case, make sure your PackManager.java has this method
definition:
private void runWholeProgramPacks() {
if (Options.v().whole_shimple()) {
ShimpleTransformer.v().transform();
getPack("cg").apply();
getPack("wstp").apply();
getPack("wsop").apply();
} else {
getPack("cg").apply();
getPack("wjtp").apply();
getPack("wjop").apply();
getPack("wjap").apply();
}
}
Also that PackManager.class is newly compiled and that your CLASSPATH
is pointing to the right stuff in case the update wasn't "in place".
Cheers,
Navin.
