[rvm-research] Optimizing compiler debugging

I have just a small question: I'm debugging a modification that I
introduced on the optimizing compiler related to the multiplication and
division by constant code in class Simplifier, and I'm using prototype-opt,
OptTestHarness and its options to study the intermediate representation
generated by the modifications. Using this, I can see the effect of them,
but when I try to run using for example the general command for the
optimizing compiler "./rvm -X:aos:initial_compiler=opt
-X:aos:enable_recompilation=false -X:opt:print_all_ir=true Foo" it
generates a different intermediate representation. Is there any specific
reason for this, maybe related to the different steps of optimizing? Or is
there more options that I should put in order to see the changes brought by
the modification on the IR?

Thank you for your time.
