Detailed Description

trace. All information required to process and calculate the computational delay is stored in TraceInfo objects. The memory request fields for a load or store instruction are also included here. Note that the structure TraceInfo does not store pointers to children or parents. The dependency trace is maintained as an ordered collection of records for writing to the output trace and not as a tree data structure.
