Bytecode program analysis method and device, equipment and medium

The invention discloses a bytecode program analysis method and device, equipment and a medium, and relates to the technical field of computers, and the method comprises the steps: obtaining a to-be-analyzed target bytecode program, and generating an initial control flow diagram corresponding to the target bytecode program; determining connectivity between an initial node and other nodes in the initial control flow graph, and taking other nodes which cannot be communicated with the initial node as first-class abnormal nodes; wherein other nodes are nodes except the initial node in the initial control flow diagram; and performing path deletion on the initial control flow diagram according to the first type of abnormal nodes to generate a first optimized control flow diagram, and analyzing the target byte code program according to the first optimized control flow diagram. According to the method, meaningless analysis paths are eliminated from the control flow diagram, the analysis process is simplified, meaningl
