+suppress error reports for out-of-bound access to globals with certain
+names and types (you may only specify class or struct types).

+You may use an ``init`` category to suppress reports about initialization-order
+problems happening in certain source files or with certain global variables.

+Introduction
+============
+
+This document describes the way to disable or alter the behavior of
+sanitizer tools for certain source-level entities by providing a special
+file at compile-time.
+
+Goal and usage
+==============
+
+User of sanitizer tools, such as :doc:`AddressSanitizer`, :doc:`ThreadSanitizer`
+or :doc:`MemorySanitizer` may want to disable or alter some checks for
+certain source-level entities to:
+
+* speedup hot function, which is known to be correct;
+* ignore a function that does some low-level magic (e.g. walks through the
+  thread stack, bypassing the frame boundaries);
+* ignore a known problem.
+
+To achieve this, user may create a file listing the entities he wants to
+ignore, and pass it to clang at compile-time using
+``-fsanitize-blacklist`` flag. See :doc:`UsersManual` for details.
+
+Example
+=======
+
+.. code-block:: bash
+
+  $ cat foo.c
+  #include <stdlib.h>
+  void bad_foo() {
+    int *a = (int*)malloc(40);
+    a[10] = 1;
+  }
+  int main() { bad_foo(); }
+  $ cat blacklist.txt
+  # Ignore reports from bad_foo function.
+  fun:bad_foo
+  $ clang -fsanitize=address foo.c ; ./a.out
+  # AddressSanitizer prints an error report.
+  $ clang -fsanitize=address -fsanitize-blacklist=blacklist.txt foo.c ; ./a.out
+  # No error report here.
+
+Format
+======
+
+Each line contains an entity type, followed by a colon and a regular
+expression, specifying the names of the entities, optionally followed by
+an equals sign and a tool-specific category. Empty lines and lines starting
+with "#" are ignored. The meanining of ``*`` in regular expression for entity
+names is different - it is treated as in shell wildcarding. Two generic
+entity types are ``src`` and ``fun``, which allow user to add, respectively,
+source files and functions to special case list. Some sanitizer tools may
+introduce custom entity types - refer to tool-specific docs.
+
+.. code-block:: bash
+
+    # Lines starting with # are ignored.
+    # Turn off checks for the source file (use absolute path or path relative
+    # to the current working directory):
+    src:/path/to/source/file.c
+    # Turn off checks for a particular functions (use mangled names):
+    fun:MyFooBar
+    fun:_Z8MyFooBarv
+    # Extended regular expressions are supported:
+    fun:bad_(foo|bar)
+    src:bad_source[1-9].c
+    # Shell like usage of * is supported (* is treated as .*):
+    src:bad/sources/*
+    fun:*BadFunction*
+    # Specific sanitizer tools may introduce categories.
+    src:/special/path/*=special_sources
