> The TargetMachine interface functions addPassesToEmitFile and addPassesToEmitMC now require a reference to an MMI; This IMO breaks the abstraction of the TargetMachine, since an MMI requires a LLVMTargetMachine, and if you have a TargetMachine you should do the dreaded casting to LLVMTargetMachine in order to create it. Now I created a factory method for MMIs in the TargetMachine interface to remedy this issue, but I still don't like it since again, it is only implemented for LLVMTargetMachine.


I don't quite follow what the issue is here, but I'm off until Tuesday so I'll look again next week (I hope)
