With this patch, the compiler-rt build will successfully detect that Clang can target i686. The open_memstream.cc test is a little funny. Before my patch, it was invoked with "-m32 -m64". To make it work after my -march change, I had to add '-march=x86-64'.

This is all that is needed for CFI diagnostics; UBSan's -fsanitize=vptr also requires an implementation of __ubsan::checkDynamicType. - Build the sanitizer runtimes against the release version of the C runtime, even in debug builds. - Accommodate demangling differences in tests.

2015-07-06[asan] Add OS X 10.11's new dyld interposition supportKuba Brecka2-4/+40
On OS X 10.11 (which is currently a public beta), the dynamic linker has been improved so that it doesn't require the use of DYLD_INSERT_LIBRARIES in order for interposition/wrappers to work. This patch adds support of this behavior into ASan – we no longer need to re-exec in case the env. variable is not set. Reviewed at http://reviews.llvm.org/D10924 llvm-svn: 241487

2015-07-02UBSan: Enable runtime library tests on Windows, and get most tests passing.Peter Collingbourne21-59/+105
Specifically: - Disable int128 tests on Windows, as MSVC cl.exe does not support int128, so we might not have been able to build the runtime with int128 support. - XFAIL the vptr tests as we lack Microsoft ABI support. - XFAIL enum.cpp as UBSan fails to add the correct instrumentation code for some reason. - Modify certain tests that build executables multiple times to use unique names for each executable. This works around a race condition observed on Windows. - Implement IsAccessibleMemoryRange for Windows to fix the last misaligned.cpp test. - Introduce a substitution for testing crashes on Windows using KillTheDoctor.

2015-06-27[msan] Fix infinite recursion when _Unwind_Backtrace calls memcpyJay Foad1-1/+2
Summary: On PPC64, half the msan tests fail with an infinite recursion through GetStackTrace like this: #0 __msan::GetStackTrace #1 __msan_memcpy #2 ?? () from /lib64/libgcc_s.so.1 #3 ?? () from /lib64/libgcc_s.so.1 #4 _Unwind_Backtrace #5 __sanitizer::BufferedStackTrace::SlowUnwindStack #6 __sanitizer::BufferedStackTrace::Unwind #7 __msan::GetStackTrace #8 __interceptor_calloc #9 _dl_allocate_tls #10 pthread_create@@GLIBC_2.17 #11 __interceptor_pthread_create #12 main The problem is that we call _Unwind_Backtrace to get a stack trace; but _Unwind_Backtrace calls memcpy, which we intercept and try to get another stack trace. This patch fixes it in __msan_memcpy by skipping the stack trace if IsInSymbolizer(). This works because GetStackTrace already creates a SymbolizerScope to "block reports from our interceptors during _Unwind_Backtrace".
