-Introduction
-============
-RealtimeSanitizer (a.k.a. RTSan) is a real-time safety testing tool for C and C++
-projects. RTSan can be used to detect real-time violations, i.e. calls to methods
-that are not safe for use in functions with deterministic runtime requirements.
-RTSan considers any function marked with the ``[[clang::nonblocking]]`` attribute
-to be a real-time function. If RTSan detects a call to ``malloc``, ``free``,
-``pthread_mutex_lock``, or anything else that could have a non-deterministic
-execution time in a function marked ``[[clang::nonblocking]]``
-RTSan raises an error.
-
-The runtime slowdown introduced by RealtimeSanitizer is negligible.
-
-How to build
-============
-
-Build LLVM/Clang with `CMake <https://llvm.org/docs/CMake.html>` and enable the
-``compiler-rt`` runtime. An example CMake configuration that will allow for the
-use/testing of RealtimeSanitizer:
-
-.. code-block:: console
-
- $ cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="compiler-rt" <path to source>/llvm
-
-Usage
-=====
-
-There are two requirements:
-
-1. The code must be compiled with the ``-fsanitize=realtime`` flag.
-2. Functions that are subject to real-time constraints must be marked
- with the ``[[clang::nonblocking]]`` attribute.
-
-Typically, these attributes should be added onto the functions that are entry
-points for threads with real-time priority. These threads are subject to a fixed
-callback time, such as audio callback threads or rendering loops in video game
-code.
-
-.. code-block:: console
-
- % cat example_realtime_violation.cpp
- #include <vector>
-
- void violation() [[clang::nonblocking]]{
- std::vector<float> v;
- v.resize(100);
- }
-
- int main() {
- violation();
- return 0;
- }
- # Compile and link
- % clang++ -fsanitize=realtime -g example_realtime_violation.cpp
-
-If a real-time safety violation is detected in a ``[[clang::nonblocking]]``
-context, or any function invoked by that function, the program will exit with a
-non-zero exit code.
-
-.. code-block:: console
-
- % clang++ -fsanitize=realtime -g example_realtime_violation.cpp
- % ./a.out

----------
-- Introduced Realtime Sanitizer, activated by using the -fsanitize=realtime
- flag. This sanitizer detects unsafe system library calls, such as memory
- allocations and mutex locks. If any such function is called during invocation
- of a function marked with the ``[[clang::nonblocking]]`` attribute, an error
- is printed to the console and the process exits non-zero.
- Added the ``-fsanitize-undefined-ignore-overflow-pattern`` flag which can be
used to disable specific overflow-dependent code patterns. The supported

-Introduction
-============
-RealtimeSanitizer (a.k.a. RTSan) is a real-time safety testing tool for C and C++
-projects. RTSan can be used to detect real-time violations, i.e. calls to methods
-that are not safe for use in functions with deterministic runtime requirements.
-RTSan considers any function marked with the ``[[clang::nonblocking]]`` attribute
-to be a real-time function. If RTSan detects a call to ``malloc``, ``free``,
-``pthread_mutex_lock``, or anything else that could have a non-deterministic
-execution time in a function marked ``[[clang::nonblocking]]``
-RTSan raises an error.
-
-The runtime slowdown introduced by RealtimeSanitizer is negligible.
-
-How to build
-============
-
-Build LLVM/Clang with `CMake <https://llvm.org/docs/CMake.html>` and enable the
-``compiler-rt`` runtime. An example CMake configuration that will allow for the
-use/testing of RealtimeSanitizer:
-
-.. code-block:: console
-
- $ cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="compiler-rt" <path to source>/llvm
-
-Usage
-=====
-
-There are two requirements:
-
-1. The code must be compiled with the ``-fsanitize=realtime`` flag.
-2. Functions that are subject to real-time constraints must be marked
- with the ``[[clang::nonblocking]]`` attribute.
-
-Typically, these attributes should be added onto the functions that are entry
-points for threads with real-time priority. These threads are subject to a fixed
-callback time, such as audio callback threads or rendering loops in video game
-code.
-
-.. code-block:: console
-
- % cat example_realtime_violation.cpp
- #include <vector>
-
- void violation() [[clang::nonblocking]]{
- std::vector<float> v;
- v.resize(100);
- }
-
- int main() {
- violation();
- return 0;
- }
- # Compile and link
- % clang++ -fsanitize=realtime -g example_realtime_violation.cpp
-
-If a real-time safety violation is detected in a ``[[clang::nonblocking]]``
-context, or any function invoked by that function, the program will exit with a
-non-zero exit code.
-
-.. code-block:: console
-
- % clang++ -fsanitize=realtime -g example_realtime_violation.cpp
- % ./a.out

Sanitizers
----------
-- Introduced Realtime Sanitizer, activated by using the -fsanitize=realtime
- flag. This sanitizer detects unsafe system library calls, such as memory
- allocations and mutex locks. If any such function is called during invocation
- of a function marked with the ``[[clang::nonblocking]]`` attribute, an error
- is printed to the console and the process exits non-zero.
- Added the ``-fsanitize-undefined-ignore-overflow-pattern`` flag which can be
used to disable specific overflow-dependent code patterns. The supported
