At first sight, the only thing that needs to be done to "support" cs_opt_stackframe for the JVM target is to always set pi_has_stackparameter there. > The parentfp optimization need to be tied to some generic optimization. > cs_opt_remove_empty_proc looks good for this. That feels rather unrelated to me.
