[Soot-list] Can soot have multiple runs to collect some info beforehand?

[Kelvin Tian]

Dear Eric,

    Great thanks for your help!  I've successfully output the line number of
the statements I want.
    But I found one problem with Soot, Soot seems to instrument functions up
to down in a class file.  Currently I output all the instrumentation just
before the return statement in main() function by adding some output
statements.  But that's on condition of that all other functions are above
main() function. If I put some functions below main() function, the
instrumentation info of those functions would not output, as Soot instrument
those functions after instrumenting main() function.   So does Soot have
some support for several runs to collect some information beforehand, which
means previous runs of soot can collect some information useful for later
runs of Soot?

   BTW, what's the good location to output all the profiling information,
other than before the return statement in main() function?
