Max Moroz 10ed68189a Add FuzzedDataProvider helper class / single header library. 
Summary:
This class is useful for writing fuzz target that have multiple inputs.

Current CL imports the existing `FuzzedDataProvider` from Chromium
without any modifications. Feel free to review it thoroughly, if you're
interested, but I'd prefer changing the class in a follow up CL.

The CL also introduces an exhaustive test for the library, as the behavior
of `FuzzedDataProvider` must not change over time.

In follow up CLs I'm planning on changing some implementation details
(I can share a doc with some comments to be addressed). After that, we
will document how `FuzzedDataProvider` should be used.

I have tested this on Linux, Windows and Mac platforms.

dataflow [libFuzzer] DFT: when dumping coverage, also dump the total number of instrumented blocks in a function; update merge_data_flow.py to merge coverage 2019-05-08 17:20:09 +00:00
scripts [libFuzzer] remove the data-flow-trace (DFT) python scripts; their functionality is now part of libFuzzer proper; also write functions.txt to the disk only if this file doesn't exist yet 2019-05-23 01:03:42 +00:00
