Dag representation of basic block
WebDAG representation of basic blocks Recall: DAG representation of expressions leaves corresponding to atomic operands, and interior nodes corresponding to operators. A … WebDirected Acyclic Graph. Directionally Acyclic Graph (DAG) is adenine tool so represented who structure of basic blocks, helps to notice the flow of values floating among the basic blocks, and offers optimization moreover. DAG provides easy metamorphosis on basic blocks. DAG can be tacit here: Leaf nodes represent keywords, names or constants.

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 ...

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.
