1AddressSanitizer (http://code.google.com/p/address-sanitizer) and
2ThreadSanitizer (http://code.google.com/p/thread-sanitizer/) are
3projects initially developed by Google Inc.
4Both tools consist of a compiler module and a run-time library.
5The sources of the run-time library for these projects are hosted at
6http://llvm.org/svn/llvm-project/compiler-rt in the following directories:
7  include/sanitizer
8  lib/sanitizer_common
9  lib/interception
10  lib/asan
11  lib/tsan
12  lib/lsan
13  lib/ubsan

15Trivial and urgent fixes (portability, build fixes, etc.) may go directly to the
16GCC tree.  All non-trivial changes, functionality improvements, etc. should go
17through the upstream tree first and then be merged back to the GCC tree.
18The merges from upstream should be done with the aid of the merge.sh script;
19it will also update the file MERGE to contain the upstream revision
20we merged with.
