Dan Albert 15c010a37e Base regex code on char_class_type.
__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.

This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Alexey Samsonov 9d7323eca3 Fix linking with just-built libc++abi (added in r214037).
Pass target name ("cxxabi") to target_link_libraries(cxx ...) to ensure
that linker is able to locate just-built libc++abi in the build tree,
instead of relying on "-lc++abi" linker flag.

Marshall Clow 51510e7f4c Fix PR#20471. Add a cast in __align_it to ensure that the bit twiddling is done at the correct size. A better solution, IMHO, would be to declare vector<bool>::__bits_per_word as 'size_type', rather than 'unsigned', but that's a possible ABI change.

Dan Albert 55d029e6ae Better defaults for in-tree libc++ with cmake.
This will detect if you are building libcxx in-tree and libcxxabi is
available.  If so, it will default to using the in-tree libcxxabi by
setting LIBCXX_CXX_ABI to "libcxxabi", LIBCXX_LIBCXXABI_INCLUDE_PATHS to
"${CMAKE_SOURCE_DIR}/projects/libcxxabi/include" and will add "cxxabi"
as a proper dependency.

Eric Fiselier aa873af53d [libcxx] expose experimental::erased_type for all standard versions.
Summary: The polymorphic allocator implementation would greatly benefit by defining virtual functions in the dynlib instead of inline. In order to do that some types are going to have to be available outside of c++1y. This is the first step.

David Majnemer 8b51260274 Fix std::make_heap's worst case time complexity
std::make_heap is currently implemented by iteratively applying a
siftup-type algorithm.  Since sift-up is O(ln n), this gives
std::make_heap a worst case time complexity of O(n ln n).

The C++ standard mandates that std::make_heap make no more than O(3n)
comparisons, this makes our std::make_heap out of spec.

Fix this by introducing an implementation of __sift_down and switch
std::make_heap to create the heap using it.
This gives std::make_heap linear time complexity in the worst case.

This fixes PR20161.

Marshall Clow 0df880209d In response to bug #20362, change the order of operations in vector move assignment so that if the allocator move assignment throws, we aren't left with two objects pointing at the same memory. This is not a complete fix; I am unconvinced that a complete fix is possible. With this change in place, we will leak the old contents of the vector. LWG issue #2106, when adopted, will make this problem illegal. Thanks to Thomas Koeppe for the report and analysis.

Eric Fiselier 531d8b2bc4 [libcxx] Add <experimental/utility> header for LFTS.
Summary:
This patch adds the `<experimental/utility>` header as specified in the latest draft of the library fundamentals TS.

`<experimental/utility>` only contains `class erased_type`. 

This patch also updates the documentation to list the `erased_type` class as "initial implementation complete".

Test Plan:
Three test cases where added:

1. Test that `_LIBCPP_VERSION` is defined.
2. Test that `<utility>` has been included.
3. Test that `erased_type` is in the correct namespace and is constexpr default constructible.

Nico Weber 1d1b46cdf7 Make locales (and transitively, std::endl) work reliably with gcc.
libc++ currently relies on undefined initialization order of global
initializers when using gcc:

1. __start_std_streams in iostream.cpp calls locale:🆔:_init, which assigns
   an id to each locale::facet in an initializer

2. Every facet has a static locale::id id, whose constructor sets the facet's
   id to 0

If 2 runs after 1, it clobbers the facet's assigned consecutive id, causing
exceptions to be thrown when e.g. running code like "cout << endl".

To fix this, let _LIBCPP_CONSTEXPR evaluate to "constexpr" instead of nothing
with gcc.  locale::id's constructor is marked _LIBCPP_CONSTEXPR, which ensures
that it won't get an initializer that could potentially run after the
iostream.cpp initializer. (This remains broken when building with msvc.)

Also switch constexpr-specific code in bitset to use __SIZEOF_SIZE_T__ instead
of __SIZE_WIDTH__, because gcc doesn't define the latter.

Pair-programmed/debugged with Dana Jansens.

David Majnemer 1e9592a9c7 [libc++] random_device fails if open returns zero
random_device::random_device(const string&) wrongly assumes that open
can only validly return a file descriptor greater than zero.

This results in random_device believing that it didn't successfully open
the device causing it to throw in it's constructor, this ends up leaking
a file descriptor.

The fix is simple, don't error on file descriptors which are zero.

Marshall Clow 91c71ddd8d Define a new macro in libc++ named '_LIBCPP_HAS_NO_ASAN'. When this is defined,
libc++ will not call address_sanitizer to detect addressing errors in the
standard library containers. This is a negative macro to enable users to
disable the libc++ checks even if they are compiling with address sanitizer
enabled by defining this macro.

At the present time, there is no code in libc++ that looks at this macro.
That will come soon. This is just infrastructure.

Marshall Clow 1641a7c1cb Implement LWG issue #2135. If something goes wrong in condition_variable::wait, call terminate() rather than throwing an error.

Also mark #2104 as complete. Leave the implementation in libc++ as noexcept, since 
implementations are allowed to add noexcept to non-virtual calls. If we throw from
unique_lock& operator=(unique_lock&& u), then that means the preconditions were violated,
and calling terminate() (as a result of throwing from a noexcept function) is as
good example of undefined behavior as any other.

Always use list(APPEND) as it will perform the desired action even if the list

Peter Collingbourne 8845dbd798 Do not derive __gnu_cxx::hash<T> from std::hash<T>.
Instead, define explicit specializations for the basic types listed in
the SGI documentation. This solves two problems:

 1) Helps avoid silent ODR violations caused by the absence of a
    user-supplied __gnu_cxx::hash specialization in cases where a std::hash
    specialization exists (e.g. for std::string).

 2) __gnu_cxx::hash semantics are slightly different to those of
    std::hash (for example, the former may dereference a pointer argument)
    so it is inappropriate for __gnu_cxx::hash to receive std::hash
    specializations by default.
