[LLVMdev] Probably FAQ: can you insert BRCONDs during TargetLowering::LowerOperation?

[Scott Michel]

Chris:

It occurred to me this morning that maybe the general solution to  
this particular type of problem is a custom/target-dependent DAG  
inserter pass, analogous to target lowering and DAG legalization. I'm  
not sure if this pass happens before or after legalization. Worth  
considering?

I suppose the best way to discuss this is to just write the code.  
However, some preliminary discussion is probably worthwhile to make  
sure that a target-dependent DAG inserter pass is invoked in the  
right place in the existing pass stream.
