Explanation:
Detailed explanation-1: -Basic blocks can have multiple predecessors and successors, however there is a MIR pass ( CriticalCallEdges ) that removes critical edges, which are edges that go from a multi-successor node to a multi-predecessor node. This pass is needed because some analyses require that there are no critical edges in the CFG.
