fff544efbd Explicitly include <sched.h> for sched_yield()
It might be implicitly included by <pthread.h> (and that's why it worked
so far), but it's not guaranteed (for example, this is not the case with
newlib).

c934ca7237 [libcxx] Add logic to probe compiler in tests.
Summary:
This patch probes the cxx compiler used during testing by getting it to dump its predefined macros. Based on the value of these macros the compiler name and compiler name + version are added to the available features.

There are three compiler names:
- `clang`
- `apple-clang`
- `gcc`.

The available features added are equivalent to:
- `'%s' % compiler_name`
- `'%s-%s.%s' % compiler_name, major_version, minor_version`

This information can be used to XFAIL tests on different compilers / versions.

7330ed3228 Add support for building and testing libc++ without threads to CMake.
Currently hacks must be used in to configure and build libc++ without threads
when using CMake. This patch adds CMake options to enable/disable building with
threads and a monotonic clock.

This patch also propagates the configuration information to lit so the tests
are properly configured as well.

93cfd7fc4e libc++: support NaCl when building thread.cpp
Summary: NaCl shouldn't include sysctl.h when trying to determine std:🧵:hardware_concurrency, it should instead use sysconf(_SC_NPROCESSORS_ONLN) through unistd.h. No test needs to be changed, since hardware_concurrency.pass.cpp already tests that std:🧵:hardware_concurrency > 0.

2bd5ffd330 libc++: add NaCl and PNaCl support for std::random_device
Summary:
The NaCl sandbox doesn't allow opening files under /dev, but it offers an API which provides the same capabilities. This is the same random device emulation that nacl_io performs for POSIX support, but nacl_io is an optional library so libc++ can't assume that device emulation will be performed. Note that NaCl only supports /dev/urandom, not /dev/random.

This patch also cleans up some of the preprocessor #endif, and fixes the test for Win32 (it accepts any token, and would therefore never throw regardless of the token provided).

877409a1c7 Add better support for custom test runners.
Summary:
I finally got around to merging the many, many changes to lit.cfg into
Android's libc++. This patch makes it simpler to actually use a custom
configuration and test format.

First, I've factored out _build, _run, and _clean methods from
_execute_test, since these are the likely parts that will need to be
overridden. This is likely a first step in the work jroelofs has been
doing with improving cross-compiling test execution.

Second, I've added a `configuration_variant` to the config. This
entry, if present, is a string that forms the prefix of the class that
is to be used to configure the test runner. For example, Android sets
`config.configuration_variant = 'Android'`, and this causes an object
of type `AndroidConfiguration` to be constructed.

As an example of how this will be used, see:
https://android-review.googlesource.com/#/c/116022/

c2f0e465ca Overhaul and separate nullptr_t tests to pass with C++03.
The standard requires that nullptr_t can be reinterpret_cast to an integral type
at least the size of nullptr_t. There is no way to emulate this conversion in
the C++03 nullptr_t implementation. The test for this conversion has been moved
to a new test and marked XFAIL with c++03.

This recommits what was originally r222296.

221907d782 Cleanup quick_exit tests and get them passing in C++03.
Wrap the original test in _LIBCPP_HAS_QUICK_EXIT so it only runs when we have
quick_exit and add two new tests that check that when _LIBCPP_HAS_QUICK_EXIT
is not defined then no definition of std::at_quick_exit or std::quick_exit are
available.

88aae920ef Implement void_t from N3911. Add a private version for use in the library before C++1z. Update the 1z status page, marking a bunch of issues that don't require library changes as complete (2129, 2212, 2230, 2233, 2325, 2365, 2376)

275b6bbe1c Add tests to ensure that reference_wrapper<T> is trivially copyable. This was added to C++1z with the adoption of N4277, but libc++ already implemented it as a conforming extension. No code changes were needed, just more tests.

8e2855ce0b [libcxx] Refactor CMakeLists.txt handling of compile and link flags to suppress warnings.
Summary:
Currently we have 5 variables that are used to specify options for building libcxx
1. `LIBCXX_CXX_FEATURE_FLAGS`
2. `LIBCXX_CXX_WARNING_FLAGS`
3. `LIBCXX_CXX_REQUIRED_FLAGS`
4. `compile_flags` (in libcxx/lib)
5. `link_flags` (in libcxx/lib)

The first three all get put into `CMAKE_CXX_FLAGS`. 
This changes the way flags are handled by only using 3 different options:

1. `LIBCXX_CXX_FLAGS` - general compile and link flags.
2. `LIBCXX_COMPILE_FLAGS` - compile only flags.
3. `LIBCXX_LINK_FLAGS` - link only flags.

This patch also removes the warning about `-nostdinc++` being unused during linking.

0364baca04 Split thread test into two parts. Mark one as XFAIL with ASAN.
The second part of the test checks that std::terminate is called when a running
thread is move assigned to. Calling std::terminate prevents some of the destructors
to be called and ASAN fires on this.

017e1aab88 Initialize pointer in string conversion helpers to prevent MSAN diagnostic.
Since the initialization of the pointer happens across the libc library boundry
MSAN will not know the pointer was initialized. This fixes MSAN failures in
test/strings/string.conversions.

50ada3a8f7 [libcxx] Fix memory leak in strstream tests.
Summary: The strstream function `str()` sets `freeze(true)`. When `freeze` is true the destructor is not allowed to free any dynamically allocated memory. The memory leak causes ASAN to fail on these tests. To ensure memory is deallocated `strstream.freeze(false)` is called at the end of the tests.

d759095887 [libcxx] Fix vector annotator size increase in vector::insert(pos, count, value)
Summary:
The size of the vector is being increased by `__n` during the call to `__move_range` and not by 1.
This fixes a test failure in `containers/sequences/vector/vector.modifiers/insert_iter_size_value.pass.cpp` when using ASAN.
