+Usage with UndefinedBehaviorSanitizer
+=====================================
+
+The arithmetic overflow sanitizers ``unsigned-integer-overflow`` and
+``signed-integer-overflow`` as well as the implicit integer truncation
+sanitizers ``implicit-signed-integer-truncation`` and
+``implicit-unsigned-integer-truncation`` support the ability to adjust
+instrumentation based on type.
+
+.. code-block:: bash
+
+  $ cat foo.c
+  void foo() {
+    int a = 2147483647; // INT_MAX
+    ++a;                // Normally, an overflow with -fsanitize=signed-integer-overflow
+  }
+  $ cat ignorelist.txt
+  [signed-integer-overflow]
+  type:int
+  $ clang -fsanitize=signed-integer-overflow -fsanitize-ignorelist=ignorelist.txt foo.c ; ./a.out
+  # no signed-integer-overflow error
+
+Supplying ``ignorelist.txt`` with ``-fsanitize-ignorelist=ignorelist.txt``
+disables overflow sanitizer instrumentation for arithmetic operations
+containing values of type ``int``, for example. Custom types may be used.
+
+The following SCL categories are supported: ``=allow``, ``=skip`` and
+``=forbid``. The ``allow`` category is the default for any entry and specifies
+that the query, if matched, will have its sanitizer instrumentation ignored.
+Conversely, both ``skip`` and ``forbid`` cause their queries, if matched, to be
+left out of the ignorelist -- essentially ensuring sanitizer instrumentation
+remains for those types. This is useful for whitelisting specific types.
+
+With this, one may disable instrumentation for all types and specifically allow
+instrumentation for one or many types.
+
+.. code-block:: bash
+
+  $ cat ignorelist.txt
+  [implicit-signed-integer-truncation]
+  type:*=allow
+  type:T=skip
+  $ cat foo.c
+  typedef char T;
+  typedef char U;
+  void foo(int toobig) {
+    T a = toobig;    // instrumented
+    U b = toobig;    // not instrumented
+    char c = toobig; // also not instrumented
+  }
+
+Note that ``skip`` and ``forbid`` operate exactly the same in this context and
+both options exist simply for conformity with the `-fprofile-list
+<https://clang.llvm.org/docs/UsersManual.html#instrumenting-only-selected-files-or-functions>`_
+syntax for adjusting profile instrumentation. You do not need to specify any
+`default:<type>` for ``-fsanitize-ignorelist`` SSCLs, though.
