clang tool chain support

Does Xcode clang 12 support address sanitizer for arm64 CPU? when we pass -fsanitize=address to both compilation and linker (clang), the library is not linked, got bunch undefined symbols of *asan*. What is the library name for arm64 if supported? on my MAC, under  /Users/usrname/tools/xcode_installs/xcode_Azul18A373_YellowstoneE11E146/Xcode.app/Contents/Developer/Toolchains/iOS14.0.xctoolchain/usr/lib/clang/12.0.0/lib/darwin/ I see these: ls *asan*  libclang_rt.asan_ios_dynamic.dylib  libclang_rt.asan_iossim_dynamic.dylib  libclang_rt.asan_osx_dynamic.dylib None seems for arm64. We are using command line to do build, not the xcode gui.
