Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
...
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

Resuming work on the compiler-rt CMake build at long long last. In order
...
to get it working again, two changes were needed:
- I had to give up on glob-based file expansion. This just isn't well
supported by CMake, and until we convince upstream there of its value,
it's not worth dealing with the pain.
- Add the common library as otherwise even ASan won't build.
This now builds again, although the "correctness" of it is a touch
debatable. ;] Specifically, there is no merging of the common runtime
library with the asan runtime library into a single archive file. I'm
not really sure what the best technique is for that, and it may be
influenced by the ongoing discussion about how best to link runtime
libraries.
Note of course that this is still very much WIP. It doesn't entirely
work yet, and remains disabled by the LLVM projects/CMakeLists.txt until
it is in a working state.

It is an analogue of addr2line utility and should allow to map instruction address to a location

Fix GetFrameNameByAddr hitting stale stack guards.
...
In the current implementation AsanThread::GetFrameNameByAddr scans the
stack for a magic guard value to locate base address of the stack
frame. This is not reliable, especially on ARM, where the code that
stores this magic value has to construct it in a register from two
small intermediates; this register can then end up stored in a random
stack location in the prologue of another function.
With this change, GetFrameNameByAddr scans the shadow memory for the
signature of a left stack redzone instead. It is now possible to
remove the magic from the instrumentation pass for additional
performance gain. We keep it there for now just to make sure the new
algorithm does not fail in some corner case.

[tsan] First commit of ThreadSanitizer (TSan) run-time library.
...
Algorithm description: http://code.google.com/p/thread-sanitizer/wiki/ThreadSanitizerAlgorithm
Status:
The tool is known to work on large real-life applications, but still has quite a few rough edges.
Nothing is guaranteed yet.
The tool works on x86_64 Linux.
Support for 64-bit MacOS 10.7+ is planned for late 2012.
Support for 32-bit OSes is doable, but problematic and not yet planed.
Further commits coming:
- tests
- makefiles
- documentation
- clang driver patch
The code was previously developed at http://code.google.com/p/data-race-test/source/browse/trunk/v2/
by Dmitry Vyukov and Kostya Serebryany with contributions from
Timur Iskhodzhanov, Alexander Potapenko, Alexey Samsonov and Evgeniy Stepanov.
