Attached is a follow up patch to your 2 devirtualization patches. Now that compute_known_type_jump_func may be called with SSA_NAME argument (from ipa_try_devirtualize_immediately) we need to make it handle SSA_NAMEs. One way to do so it to defer the job to detect_type_change_ssa, below patch implements this approach. Note that the patch relies on detect_type_change to initialize JFUNC, as is done in your patch at http://gcc.gnu.org/ml/gcc-patches/2011-01/msg01033.html. Without that patch we need to initialize JFUNC inside compute_known_type_jump_func, which may be a cleaner solution. I encourage you to include this small fix in the main body of one of your patches and claim credit for it. You will spare me a test-submission cycle that way :-).
