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. WebOct 20, 2024 · 1.

WebDAG representation of basic blocks Recall: DAG representation of expressions leaves corresponding to atomic operands, and interior nodes corresponding to operators. A node N has multiple parents - N is a common subexpression.
