Integrate Kostya's clang-proto-fuzzer with LLVM.
Summary:
The clang-proto-fuzzer models a subset of C++ as a protobuf and
uses libprotobuf-mutator to generate interesting mutations of C++
programs. Clang-proto-fuzzer has already found several bugs in
Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747,
https://bugs.llvm.org/show_bug.cgi?id=33749).
As with clang-fuzzer, clang-proto-fuzzer requires the following
cmake flags:
- CMAKE_C_COMPILER=clang
- CMAKE_CXX_COMPILER=clang++
- LLVM_USE_SANITIZE_COVERAGE=YES // needed for libFuzzer
- LLVM_USE_SANITIZER=Address // needed for libFuzzer
In addition, clang-proto-fuzzer requires:
- CLANG_ENABLE_PROTO_FUZZER=ON
clang-proto-fuzzer also requires the following dependencies:
- binutils // needed for libprotobuf-mutator
- liblzma-dev // needed for libprotobuf-mutator
- libz-dev // needed for libprotobuf-mutator
- docbook2x // needed for libprotobuf-mutator
- Recent version of protobuf [3.3.0 is known to work]
A working version of libprotobuf-mutator will automatically be
downloaded and built as an external project.
Implementation of clang-proto-fuzzer provided by Kostya
Serebryany.
