|
|
// A data flow trace is generated by e.g. dataflow/DataFlow.cpp
|
|
// and is stored on disk in a separate directory.
|
|
//
|
|
// The trace dir contains a file 'functions.txt' which lists function names,
|
|
// oner per line, e.g.
|
|
// ==> functions.txt <==
|
|
// Func2
|
|
// LLVMFuzzerTestOneInput
|
|
// Func1
|
|
//
|
|
// All other files in the dir are the traces, see dataflow/DataFlow.cpp.
|
|
// The name of the file is sha1 of the input used to generate the trace.
|
|
//
|
|
// Current status:
|
|
// the data is parsed and the summary is printed, but the data is not yet
|
|
// used in any other way.
