Good to know. Anything against making the codegen pass manager 
accessible to users? Something like 
ExecutionEngine::getCommonCodegenPassManager() ?

Thanks,

I don't have a problem with that, the interface should be discussed  
though.  You'd want some sort of interface to say "stick this in the  
'before regalloc' bucket" etc.

What do you intend to use this for?

Actually, we can forget about that in my particular case. I wanted to 
add a pass that gathers the GC information (the GCFunctionInfo object) 
provided by the GCMachineCodeAnalysis pass. However, I didn't realize 
the GCStrategy already has a link to the GCFunctionInfos. So creating an 
interface is not needed anymore for my particular case.

Thanks,
Nicolas
