LGTM, thanks! Just a small nitpick inline.

Also, if you have the time, please document this in clang/docs/UndefinedBehaviorSanitizer.rst.



================
Comment at: compiler-rt/test/ubsan/TestCases/Integer/no-recover.cpp:3
 // RUN: %clangxx -fsanitize=unsigned-integer-overflow -fno-sanitize-recover=all -fsanitize-recover=unsigned-integer-overflow %s -o %t && %run %t 2>&1 | FileCheck %s --check-prefix=RECOVER
+// RUN: %env_ubsan_opts=silence_unsigned_overflow=1 %run %t 2>&1 | FileCheck %s --check-prefix=SILENT-RECOVER
 // RUN: %clangxx -fsanitize=unsigned-integer-overflow -fno-sanitize-recover=unsigned-integer-overflow %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefix=ABORT
----------------
You can just pass the --allow-empty flag to FileCheck instead of adding the printf.
