[LLVMdev] Reachability info in LLVM?

Thanks. that's right but I was looking for sth like "successor closure" set for each instruction 'I' that includes all reachable instructions from I. 
Does LLVM provide such a set?

Thanks alot,

Dear All,
>I am new to LLVM and want to know if LLVM provides any reachability information about the instructions inside a function? For example, is instruction 'J' reachable from the instruction 'I'? (just based on CFG)

You can just do a depth first search on the cfg?
