Add a %stdcxx11 lit substitution for -std=c++11. Windows defaults to
-std=c++14 when VS 2015 is used because the STL requires it. Harcoding
-std=c++11 in the ASan tests actually downgrades the C++ standard level,
leading to test failures.
Relax a FileCheck pattern in use-after-scope-types.cc.
Disable the sanitizer_common OOM tests. They fail on bots with low swap,
and cause other concurrently running tests to OOM.
llvm-svn: 276454
The OOM test should really only run on 32-bits, since it's hard to OOM
on x64.
The operator_array_new_with_dtor_left_oob tests need to account for the
larger array cookie on x64 (8 bytes instead of 4).
Use -std=c++14 in use-after-scope-capture.cc to avoid errors in the MSVC
2015 STL on Windows. The default there is C++14 anyway.

Summary:
These unittests are not running on windows because they are using incorrect commands.
They were not failing on 32-bits because there is a requirement: asan-64-bits.

Summary:
Avoid mismatch between imports/exports for 32-bit and 64-bits version.
The test is running grep over macros to detect which functions are
intercepted. Unfortunately, exception handlers differ in 32-bit and
64-bit.
This patch is removing the exception handlers from the test.

It seems in some situations we have clashes on very first error so test only prints "nested bug in the same thread, aborting" rather than "use-after-poison", so remove corresponding " RUN: FileCheck %s < 10.txt" line.
Also, the two last " RUN: FileCheck --check-prefix=CHECK-COLLISION %s < 1.txt || FileCheck --check-prefix=CHECK-NO-COLLISION %s < 1.txt" look wrong, they should check 10.txt. Fix these lines too.

Summary:
This aims to add support for __cpu_model and address Bug 25510. It uses
the code from lib/Support/Host.cpp for cpu detection, and creates
__cpu_model with that info.
Tested on OSX and built on Linux as well (though libgcc is the default).
The use of "asm" required -std=gnu99, hence the cmake change. Corrections
on better addressing this are welcome.
Previously reverted, up for review again to iron out outstanding issues.

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

This patch adds interceptors for dispatch_io_*, dispatch_read and dispatch_write functions. This avoids false positives when using GCD IO. Adding several test cases.

These test in this change are objc++, but are built using %clang, not %clangxx.
The reason this works is the driver has been adding -lc++ for sanitizer enabled
builds. By making these tests use %clangxx, they no longer depend on the driver
linking to c++. Doing so will allow us to prevent overlinking of libc++ for
applications.
llvm-svn: 274989
Summary:
Adds a new public interface routine __esan_report() which can be used to
request profiling results prior to abnormal termination (e.g., for a server
process killed by its parent where the normal exit does not allow for
normal result reporting).
Implements this for the working-set tool. The cache frag tool is left
unimplemented as it requires missing iteration capabilities.
Adds a new test.

Summary:
This aims to add support for __cpu_model and address Bug 25510. It uses
the code from lib/Support/Host.cpp for cpu detection, and creates
__cpu_model with that info.
Tested on OSX, it builts successfully, but the current version does
*not* resolve Bug 25510. The __cpu_model symbol is present in the
library but it only gets loaded with -all_load. This patch will not land
until this issue is clarified.
Built on Linux as well (though libgcc is the default). The use of "asm"
required -std=gnu99, hence the cmake change. Corrections on better
addressing this are welcome.

This patch adds synchronization between the creation of the GCD data object and destructor’s execution. It’s far from perfect, because ideally we’d want to synchronize the destruction of the last reference (via dispatch_release) and the destructor’s execution, but intercepting objc_release is problematic.
