Detailed Description

The struct GraphNode stores an instruction in the trace file.

The format of the trace file favours constructing a dependency graph of the execution and this struct is used to encapsulate the request data as well as pointers to its dependent GraphNodes.

◆ dependents

std::vector<GraphNode *> gem5::TraceCPU::ElasticDataGen::GraphNode::dependents
