Hi,<div>I am trying to test my project and get the code coverage with a version of clang compiler that was built from the latest llvm/clang codebase.</div><div><br></div><div>It worked for a while. But today, after I updated my local checkout, and re-build llvm, clang and compiler-rt, when I test my project again, I got the errors with undefined reference to 'llvm_gcda_start_file', 'llvm_gcda_emit_arcs', 'llvm_gcda_emit_function', and 'llvm_gcda_end_file'.</div>
<div><br></div><div>I have searched the codebase, and have found the functions are defined in GCDAProfiling.c file, but not sure why this suddenly doesn't work for me.</div><div><br></div><div>Anyone can give any suggestions?</div>
<div><br></div><div>Thanks very much in advance.</div><div>Qun</div><div><br></div><div><br></div><div><br></div>
