WebMar 6, 2024 · A flow graph is simply a directed graph. For the set of basic blocks, a flow graph shows the flow of control information. A control flow graph is used to depict how the program control is being parsed among the blocks. A flow graph is used to illustrate the flow of control between basic blocks once an intermediate code has been partitioned into ... http://cse.iitm.ac.in/~krishna/courses/2012/odd-cs3300/pm-lecture3.pdf
Web8.5: Optimization of Basic Blocks 8.5.1: The DAG Representation of Basic Blocks. The goal is to obtain a visual picture of how information flows through the block. The leaves will show the values entering the block and as we proceed up the DAG we encounter uses of these values, defs (and redefs) of values, and uses of the new values. WebThe advantage of generating code for a basic block from its dag representation is that from a dag we can easily see how to rearrange the order of the final computation sequence than we can start from a linear sequence of three-address statements or quadruples. Rearranging the order
WebThe DAG Representation of Basic Blocks. Many local optimizations can be readily performed on a directed acyclic graph (DAG) representation of a basic block. A DAG … WebDirected Acyclic Graph. Directed Acyclic Graph (DAG) is a tool that depicts the structure of basic blocks, helps to see the flow of values flowing among the basic blocks, and offers optimization too. DAG provides easy transformation on basic blocks. DAG can be understood here: Leaf nodes represent identifiers, names or constants.
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 ...
