An irreducible CFG − a loop with two entry points, e.g. goto into a while or for loop.Drawing a Control Flow Graph from CodeLet us draw a CFG for the given example to understand how the control flows through the program, combining related statements into basic blocks....

Thecfgcaptures the essence of the loop: it is a control-flow construct. The cyclic edge runs from back to the test at the head of the loop. By contrast, theastcaptures the syntax; it is acyclic but putsallthe pieces in place to regenerate the source-code for the loop. ...
Here's an example of a control flow graph for a simple procedure without loops: If the procedure has some loops, there will be a link between the block at the bottom of the loop, and the block at the beginning of the loop. When we visit the different blocks we have to make sure th...
control flow graph Control Flow Graphs Nodes Statements or Basic Blocks (Maximal sequence of code with branching only allowed at end) Edges Possible transfer of control Example:if P then S1 else S2 S3 P S1S2 S3 CFG P predecessor of S1 and S2 S1, S2 sucessors of P Finding Basic Blocks ...
yes, control flow can lead to infinite loops. this happens when the loop's exit condition is never met, causing the loop to run indefinitely. to avoid this, make sure the loop condition eventually becomes false, or use techniques like break statements or loop counters. how do functions and...
可以看到直接导出Module,Python层的控制逻辑被丢掉(即for循环被完全展开),这是因为Pytorch在导出ONNX的时候默认使用了tracing机制 而当我们使用script模式时,导出的ONNX就会保留Python层的Control Flow并将其转换成ONNX中的Loop OP。示例代码以及Netron可视化结果如下: import torch # Mixing tracing and scripting @torc...
). The value of index is set to the first number in the range (1), and the statements inside the loop are executed. In this case, the loop contains only one statement, which prints an entry from the five-times table for the current value of index. After the statement is executed, ...
A second, empty graph will be created inside the conditional node when we set the size parameter to 2. We can then populate this second graph as we have done before. We define a new createGraph() function below which demonstrates this. For clarity, the code to launch and execute the gra...
