DAG: Total nodes are 8 but nodes b + b + c + d and b + c + d are repeated so only one time will be counted so total nodes are 8 - 2 = 6. Each repeated nodes has two edges so total edges will be 10 - 4 = 6. Hence 6 and 6 is the correct answer. Download Solution PDF.

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. the werner house columbus ohio
