question: private int evaluateCost ( BasicBlock bb ) { int result = 0 ; for ( Enumeration < Instruction > e = bb . forwardRealInstrEnumerator ( ) ; e . hasMoreElements ( ) ; ) { Instruction s = e . nextElement ( ) ; if ( ! s . isBranch ( ) ) result ++ ; } return result ; }
target:  Evaluates the cost of a basic block, in number of real instructions excluding branches.
