Supported plugins

Plugin for MPI correctness checking functionality:

• Intel Message Checker, part of the Intel Trace Analyser and Collector (Commercial with free evaluation: https://www.intel.com/content/www/us/en/developer/tools/oneapi/trace-analyzer.html) version 7.1

Plugins for the GNU and LLVM compiler sanitizers:

• Address Sanitizer (also known as ASan)

  This is a memory error detector for C/C++ code. It can be used to find various memory-related issues including use after free, buffer overflows, and use after return.

  To enable the Address Sanitizer:

  1. Compile your program whilst passing the -fsanitize=address compiler option to your compiler.

  2. Enable the Address Sanitizer plugin in Linaro DDT. For information how to enable a plugin, see Use a plugin.

  When compiling with GNU 7 you must disable leak detection due to a conflict with ptrace and this aspect of the plugin.

  To disable leak detection, either:

  1. Add the following piece of code into your program:

     extern "C" int __lsan_is_turned_off() { return 1; }
     

  2. Set the LSAN_OPTIONS environment variable at runtime, using:

     LSAN_OPTIONS=detect_leaks=0
     

  Note

  ASan is not compatible with memory debugging.

• Thread Sanitizer (also known as TSan)

  This is a data race detector for C/C++ code. A data race occurs when two different threads attempt to write to the same memory at the same time.

  To enable the Thread Sanitizer:

  1. Compile your application while you pass the -fsanitize=thread compiler option to your compiler.

  2. Enable the Thread Sanitizer plugin in Linaro DDT. For information how to enable a plugin, see Use a plugin.

  Note

  TSan is not compatible with memory debugging.
