[Soot-list] Jimple optimizations before Shimple transformation

[Daniel Wainwright]

Hi Eric,

Thank you for your quick reply. Would this mean that I would have to
rewrite these optimizations myself to use them here? I assume that the
standard optimizations in the Jimple optimization pack would not be able to
operate on Shimple without modifications. Is this correct?

Thanks,
Daniel
