Welcome!

This repository is an umbrella for the three repositories previously hosted on code.google.com:

• http://code.google.com/p/address-sanitizer/
• http://code.google.com/p/thread-sanitizer/
• http://code.google.com/p/memory-sanitizer/

Since those projects started, most of the code has been moved to the LLVM Compiler Infrastructure (http://llvm.org). Here reside some pieces of infrastructure and documentation.

Below are the links to the documentation for each project.

AddressSanitizer

AddressSanitizer (ASan) is a fast memory error detector. It finds use-after-free and {heap,stack,global}-buffer overflow bugs in C/C++ programs. Learn more:

• AddressSanitizer -- how to use the tool.
• LeakSanitizer -- leak detector
• AddressSanitizer page at clang.llvm.org
• AddressSanitizerAlgorithm -- how it works.
• AddressSanitizerHowToContribute -- if you want to help.
• Read if you are working on Chromium
• Watch the presentation from the LLVM Developer's meeting (Nov 18, 2011): Video, slides.
• Our paper accepted to USENIX ATC 2012
