17 // Usage examples:
18 // To cleanup trace, <binary> --cleanup <trace file>
19 // To profile trace, <binary> --profiling <trace file>
20 // To dedup traces, <binary> --dedup <trace file directory>
21 // Cleanup trace is used to generate trace for replay test, it will replace the
22 // old trace file with a new one of the same format (VtsProfilingRecord).
23 //
24 // Profile trace will calculate the latency of each API recorded in the trace
25 // and print them out with the format api:latency. e.g.
26 // open:150231474
27 // write:842604
28 // coreInitialized:30466722
29 //
30 // Dedup trace is used to remove all duplicate traces under the given directory.
31 // A trace is considered duplicated if there exists a trace that contains the
32 // same API call sequence as the given trace and the input parameters for each
33 // API call are all the same.
