My obvious question is what are you trying to do ?

One way to count predecessor for a basic block BB is

	unsigned count = 0;
	for (pred_iterator PI = pred_begin(BB), E = pred_end(BB); PI != E; + 
+PI)
	  ++count;


pred_iteraor, pred_begin, pred_end etc.. are available through llvm/ 
Support/CFG.h
