[Soot-list] LOC in Dacapo-2006 benchmark

[Zhoulai]

Thank you a lot, Xiao.  Among others, I was doing a small benchmark with
geometric encoding. Luckily the bad result is not yet submitted!

But, the problem is now, why I counted 182 109 LOC for 'fop' benchmark
using the same Soot options? I am running soot from Eclipse, but without
that plugin. I run soot.Main.main with className  dacapo.fop.Main. This
file by itself should not contain 182109 lines, shouldn't it?  I used -app
option. The document of soot command line says,

-app
Run in application mode, processing all classes referenced by argument
classes.

How does Soot get all class referenced by argument class? By a call-graph I
suppose? It is not sufficient to read Soot's document. One needs to guess:(
Sorry  I feel totally confused.

So how can I count so few LOC for xalan, yet  so many for fop, using the
same soot options!!??

Zell.

p.s.

Here is how I specify the class file name.

        ...
        String dacapoName=config.getProperty(Configuration.DACAPONAME);
        String
JRE14="/System/Library/Frameworks/JavaVM.framework/Versions/1.4/Classes/jce.jar:/System/Library/Frameworks/JavaVM.framework/Versions/1.4/Classes/classes.jar";

     String sootClassPath=JRE14+":"+prePath+"/"+dacapoName+".jar"+":"
                + prePath+"/"+dacapoName+"-deps.jar";

        className="dacapo."+dacapoName+".Main";
