llvm dev - Apr 2013 - [LLVMdev] pass to eliminate unneeded "br" statements

I've been added various optimizer passes and I end up with code which
looks like this:

define i32 @main() uwtable {
entry:
  store i32 ()* @_main_1, i32 ()** @_main, align 8
  br label %end

end:                                              ; preds = %entry
  ret i32 0
}

Is there another pass to get rid of that "br" instruction and just
inline the "end" block?

I would think SimplifyCFG should take care of it.

Yes, thank you. I just had to get the order of my passes correct (it was
being done too early).
