Look at include/llvm/Support/CFG.h. It has a "pred_iterator"  
definition. So you can probably do something along the lines of:

	BasicBlock *BB;

	pred_iterator PI = pred_begin(BB);
	pred_iterator PE = pred_end(BB);

	for (; PI != PE; ++PI) {
	  // Do something
	}

Do a search on the code base to see examples of its use.

Cheers!
