[LLVMdev] DataFlowSanitizer only for Linux (original) (raw)

Afternoon,

I had an issue with trying to link a program with the DataFlowSanitizer functionality, this is from the libFuzzer project, and I was seeing:

clang++ -fsanitize=address -fsanitize-coverage=edge test_fuzzer.cc Fuzzer*.o

Undefined symbols for architecture x86_64:

"_dfsan_create_label", referenced from:

  fuzzer::TraceState::DFSanCmpCallback(unsigned long, unsigned long,

unsigned long, unsigned long long, unsigned long long, unsigned short, unsigned short) in FuzzerTraceState.o

  fuzzer::Fuzzer::InitializeTraceState() in FuzzerTraceState.o

"_dfsan_get_label_info", referenced from:

  fuzzer::TraceState::GetLabelRange(unsigned short) in

FuzzerTraceState.o

.....

But then looking at the docs: http://clang.llvm.org/docs/DataFlowSanitizer.html

It appears that this is only supported under Linux? Is that right? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20150706/d2a1e623/attachment.html>
