Fail to build boringssl in google testsuite

[wcventure]

Hi, I try to use Angora to build up boringssl in google's fuzzer-test-suite.

But I face some problems. Compilation failed. Some "Unknown command line argument" happened. Thank you very much if you can help.

git clone https://github.com/google/boringssl.git
cd boringssl && git checkout 894a47df2423f0d2b6be57e6d90f2bea88213382
cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_C_COMPILER="$CC" -DCMAKE_C_FLAGS="$CFLAGS -Wno-deprecated-declarations" -DCMAKE_CXX_COMPILER="$CXX" -DCMAKE_CXX_FLAGS="$CXXFLAGS -Wno-error=main"
USE_TRACK=1 make

Building ASM object ...

It is probably wrong to call angora-clang on an assembler source. Should the wrapper detect assembler sources?

[adrianherrera]

Not sure if people are still struggling with this, but I've made a PR that does exactly what @hexcoder suggested (https://github.com/AngoraFuzzer/Angora/pull/74).

However, this still requires an abilist for libcrypto (because of all the assembly files that DFSan cannot track through). To fix this I'd suggest just adding -DOPENSSL_NO_ASM=True to the CMake command in fuzzer-test-suite/boringssl-2016-02-12/build.sh. The bug still exists with these changes.
