ftfuzzer
--------
ftfuzzer.cc contains a target function for FreeType fuzzing.
It can be used with libFuzzer (http://llvm.org/docs/LibFuzzer.html)
or potentially any other similar fuzzer.
Usage:
1. Build libfreetype.a and ftfuzzer.cc using the most recent clang compiler
with these flags:
-fsanitize-coverage=edge,8bit-counters # for fuzzer coverage feedback
-fsanitize=address,signed-integer-overflow,shift # for bug checking
2. Link with libFuzzer (it contains main()).
3. Run the fuzzer on some test corpus.
The exact flags and commands may vary.
There is a continuous fuzzing bot that runs ftfuzzer:
https://github.com/google/libfuzzer-bot/tree/master/freetype.
Check the bot confituration for the most current settings.
runinput.cc contains a convenience main() function to run the target function
on a set of input files. Link it with ftfuzzer.cc and libfreetype.a
and run like "./a.out my_tests_inputs/*"
