Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

Alexey Samsonov 6f596767c3 Stub files for common symbolizer for AddressSanitizer and ThreadSanitizer tools. 
It is an analogue of addr2line utility and should allow to map instruction address to a location
in source code at run-time. It should use debug information (in DWARF) in a binary, and hopefully
it would be possible to re-use code from llvm/DebugInfo/DIContext.h

Dmitry Vyukov 7fb7330469 asan/tsan: weak interceptors 
The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc

Evgeniy Stepanov d989be1386 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.

Kostya Serebryany 4ad375f0a9 [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.

Until we work out the solution for http://code.google.com/p/address-sanitizer/issues/detail?id=65 we'd better not allow
the clients to override AddressSanitizer's signal handler.

The second part of r154390 (removing the sighandler-related tests) is not reverted, because those tests were broken
and didn't test anything.

Chandler Carruth 1f5d5c0e13 Initial, very rough cut at a new CMake build system for compiler-rt. 
Some high-level notes:

1) An explicit goal is to support building compiler-rt as a subproject
   build, checked out into the projects/compiler-rt directory. There are
   many other possible ways of building the code here, but this is
   optimized for development on LLVM/Clang/compiler-rt, and incremental
   trial and testing of the toolchain.
2) The current support is targeted at Linux. I would love to see this
   generalized to other platforms, but for the sake of simplicity in
   testing, I'm focusing here first.

Much of this patch was paired with Manuel, and I credit him with the
majority of the work here.

Some important caveats that I'll be working on in subsequent patches:

1) This uses the host compiler rather than using the just-built-clang.
2) Currently only x86 is supported.
3) Currently, none of the tests are built or run.
4) Uses CMake's builtin globbing which doesn't update correctly.
5) This is still turned off from LLVM's CMake build until these issues
   are addressed

Chandler Carruth 6acfaaf3aa Remove the old, and non-functional CMake build system from CompilerRT. 
I cannot build any part of this successfully on either Linux or Darwin,
and the replacement is worlds simpler by requiring that this be built as
a subproject of LLVM. If this breaks you for any reason, please let me
know, and let me know what your use case is.

Evgeniy Stepanov 823085a8f4 [asan] Support for %z to Printf() 
At the moment, asan internal Printf() uses %l modifier for printing
values of size_t and related types. This works, because we control
both the implementation of Printf and all its uses, but can be a
little misleading.

This change adds support for %z to Printf(). All callers that print
sizes and pointers as integers are switched to %zu / %zx.

Daniel Dunbar cdf9bf7048 make/clang_darwin: Tweak CheckArches function to force the integrated-as and use 
the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.
