[llvm-dev] using llvm DataFlowSanitizer error

[吕涛 via llvm-dev]

Hi. I'm using llvm DataFlowSanitizer. I add such code in library libtiff.

dfsan_label lt_label = dfsan_create_label("buf_offset", 0);

dfsan_set_label(lt_label, (unsigned char *)buf, size);

But when i compile libtiff with "-fsanitize=dataflow" option, then there is an error as follows:

I search on the internet, and found one answer in http://clang-developers.42468.n3.nabble.com/Problem-linking-example-program-with-DataFlow-Sanitizer-td4039375.html




So i try to use cmake to recompile the llvm. There is an error again.

Can anyone help me to solve this problem? Thank you.
