[LLVMdev] Help getting condition of branch instructions in pass

[Michael McCracken]

Hi, this is a bit of a newbie question:

I am trying to discover, given a block with a conditional and its
successors, which condition (T/F) each successor applies to.

There's almost identical code in CFGPrinter.cpp, but where it gets
called in GraphWriter.h, the child_iterator type is a pretty hairy
thing, so I still don't quite understand how to get one from a
BasicBlock in my own code...
Is there a simpler way to do it without getting into all that?
