Where does the LLVM implement the Ubsan's instrumentations?

Also you may not need all of UBSan's checks at the same time -- so pick
and choose among its checks using the finer-grained flags.
If you're really stuck against a hard limit on code size, try applying
UBSan to a subset of files in your project at a time.

Where does the LLVM implement the Ubsan's instrumentations?
...the trap-function. I hope to print the wrong code running IP address in my trap function (then, I can use llvm-symbolizer to know its code location), and I also hope to print undefined behavior specific type info, e.g. add_overflow, type_mismatch_v1, etc., which are defined in compiler-rt\lib\ubsan\ubsan_interface.inc. How should I correctly define the __my_sanitizer_trap() and let clang/llvm input relative info into my trap function?

Where does the LLVM implement the Ubsan's instrumentations?
Hello,
I'm investigating on enabling the Ubsan in my firmware. I have two questions about Ubsan:
1. I see the Ubsan run-time lib functions are defined in http://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/ubsan/ubsan_interface.inc, but I cannot find how the LLVM implement the Ubsan instrumentations. I see the Asan's instrumentation lib is in http://llvm.org/svn/llvm-project/llvm/trunk/lib/Transforms/Instrumentation/AddressSanitizer.cpp, but where is the Ubsan instrumentation lib?
2. My firmware usage scen...
