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 13Trivial and urgent fixes (portability, build fixes, etc.) may go directly to the 14GCC tree. All non-trivial changes, functionality improvements, etc. should go 15through the upstream tree first and then be merged back to the GCC tree. 16The merges from upstream should be done with the aid of the merge.sh script; 17it will also update the file MERGE to contain the upstream revision 18we merged with. 19
