[llvm] r185925 - Document LLVM_USE_SANITIZER CMake option

[Nadav Rotem]

Hi Alexey, 

I am getting this error when I configure using -DLLVM_USE_SANITIZER=Address.  Should I add any other flags ?



Scanning dependencies of target LLVMSupport

[  0%] Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/APFloat.cpp.o

clang: error: '-fsanitize-undefined-trap-on-error' required with '-fsanitize=address' option

clang: error: unsupported argument 'address' to option 'fsanitize='

make[2]: *** [lib/Support/CMakeFiles/LLVMSupport.dir/APFloat.cpp.o] Error 1

make[1]: *** [lib/Support/CMakeFiles/LLVMSupport.dir/all] Error 2

make: *** [all] Error 2







Thanks,

Nadav
