Directed Acyclic Graph Representation of basic blocks

WebDAG construction for a basic block There is a node in the DAG for each of the initial values of the variables appearing in the basic block. There is a node N associated with each statement s within the block. The children of N are those nodes corresponding to statements that are the last definitions, prior to s, of the operands used by s. WebDAG representation of basic blocks Recall: DAG representation of expressions leaves corresponding to atomic operands, and interior nodes corresponding to operators. A … WebThe basic block of each leader contains all the instructions from itself until just before the next leader. Thus, the basic block of 1 is just 1, for leader 2 the block is just 2. Leader 3, however, has a basic block consisting of instructions 3 through 9, inclusive.
