I am trying to build a DAG for a whole function. The first problem I met is to assign a user for the last instruction of each basic block, be it BRCOND or other node. There is no natural user for such nodes. Without user, it will be removed in later phases. My idea is to use it as chain for nodes in the next basic block. Is this reasonable?<br>
