Dag representation of basic block
WebMar 16, 2024 · a can be written as : b+b+c+d. 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. WebJan 12, 2024 · Directed ACyclic Graph Question 3: Consider the basic block given below. a = b + c. c = a + d. d = b + c. e = d - b. a = e + b. The minimum number of nodes and edges present in the DAG representation of the above basic block respectively are

WebWhat is Basic block and how to partition a code into basic block is discussed here. This is important because of its use in local optimization. All its impor... 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. Instruction 10's block is 10 and 11; instruction 12's block is just 12, and ...
