Michael Park 466f0653a3 Updated the XFAIL comment in variant tests.
Summary:
`ConstexprTestTypes::NoCtors` is an aggregate type (and consequently a literal type) in C++17,
but not in C++14 since it has a base class. This patch updates the comment to accurately describe the reason for the XFAIL.

Eric Fiselier 7f1604aae6 Use inline namespaces with GCC instead of __attribute__((__strong__)).
GCC 7.0.1 started warning that __attribute__((__strong__)) is depricated.
This patch switches to using inline namespace with GCC instead. I believe
this wasn't done originally in order to support older GCC versions w/o
support for inline namespaces, or because earlier versions of GCC warned
users that the STL was using an inline namespace (even though it shouldn't affect users).

However I believe all of the above problems are gone for GCC 4.9 and greater.
Therefore switching to using inline namespaces instead of using __strong__
is the most correct behavior.

Eric Fiselier 2a1bfa98d1 [libcxx] Remove unexpected handlers in C++17
Summary:
This patch implements [P0003R5](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0003r5.html) which removes exception specifications from C++17.

The only changes to the library are removing `set_unexpected`, `get_unexpected`, `unexpected`, and `unexpected_handler`. These functions can be re-enabled in C++17 using `_LIBCPP_ENABLE_CXX17_REMOVED_UNEXPECTED_FUNCTIONS`.

@mclow.lists what do you think about removing stuff is this way?

Eric Fiselier dd3ba794ef [libc++] Fix PR 31938 - std::basic_string constructors use non-deductible parameter types.
Summary:
This patch fixes http://llvm.org/PR31938. The description below is copy/pasted from the bug:

The standard says:

template<class charT, class traits = char_traits<charT>,
         class Allocator = allocator<charT>>
class basic_string {
  using value_type = typename traits::char_type;
  // ...
  basic_string(const charT* s, const Allocator& a = Allocator());
};

libc++ actually chooses to declare the constructor as

  basic_string(const value_type* s, const Allocator& a = Allocator());

The implicit deduction guides from class template argument deduction make what was previously an implementation detail visible:

std::basic_string s = "foo"; // error, can't deduce charT.

The constructor in question is in the libc++ DSO, but fortunately it looks like fixing this will not result in an ABI break.


@rsmith How does this look? I did more than just the constructors mentioned in the PR, but IDK how far to take it.

Eric Fiselier d22c9dc422 Recommit "Split exception.cpp and new.cpp implementation into different files for different runtimes."
This recommits r294707 with additional fixes. The main difference is
libc++ now correctly builds without any ABI library.

exception.cpp is a bloody mess. It's full of confusing #ifdef branches for
each different ABI library we support, and it's getting unmaintainable.

This patch breaks down exception.cpp into multiple different header files,
roughly one per implementation. Additionally it moves the definitions of
exceptions in new.cpp into the correct implementation header.

This patch also removes an unmaintained libc++abi configuration.
This configuration may still be used by Apple internally but there
are no other possible users. If it turns out that Apple still uses
this configuration internally I will re-add it in a later commit.

Recently I turned on libc++'s debug mode assertions when
CMake is configured with -DLIBCXX_ENABLE_ASSERTIONS=ON. This
change exposed assertion failures caused by bugs in filesystem.
This patch fixes those failures.

The first bug was that `PathParser` was using front()/back()
on empty string views in order to get the address of the character.
However this is UB on empty strings. Those operations now use data()
to obtain the pointer.

The second bug was that directory_iterator attempted to capture errno when it
was unset and there was an assertion to detect this.

Saleem Abdulrasool 833cf8bdb6 filesystem: return the constructed object
This really should get identified properly by the compiler to convert to
a NVRO, but compress the code anyways.  This makes the implementation
identical to directory_iterator.cpp

Eric Fiselier 9af60c4a8b Implement LWG 2773 - std::ignore should be constexpr.
In addition to the PR for LWG 2773 this patch also ensures
that each of std::ignores constructors or assignment operators
are constexpr.

Stephan T. Lavavej ae2798fc53 [libcxx] [test] Avoid MSVC's non-Standard ABI in underlying_type.pass.cpp.
When compiled with Clang for Windows, this was emitting "enumerator value
evaluates to 4294967295, which cannot be narrowed to type 'int' [-Wc++11-narrowing]".

The test should more strenuously avoid poking this ABI deficiency (and it
already has coverage for explicitly specified underlying types).

Stephan T. Lavavej 3c56112e3f [libcxx] [test] Fix Clang -Wdeprecated-declarations with MSVC's CRT.
libcxx's tests use various C Standard Library functions that have been
marked by MSVC's CRT as deprecated by Microsoft (not by ISO).

libcxx's usage is cromulent (just checking with decltype to see if the functions
are being dragged in by various headers as required by the Standard), so
defining _CRT_SECURE_NO_WARNINGS will silence the warnings in a targeted manner.
This needs to be defined before including any CRT headers.

Also, make this file prettier.

Fixes D29138.

Marshall Clow 6a1d078560 Restore the _NOEXCEPT on the dtor of bad_optional_access. Destructors are noexcept by default, so it's not really needed, but the other exception classes have the _NOEXCEPT, and gcc complains if these are missing. I think we should remove them all - but not today.

Marshall Clow e29b1ed50b Change the base class of std::bad_optional_access. This is a (subtle) ABI change, and is in response to http://http://wg21.link/LWG2806, which I *expect* to be adopted in Kona. I am making this change now in anticipation, and will get it into 4.0, because (a) 4.0 is the first release with std::optional, and (b) I don't want to make an ABI-change later, when the user base should be significantly larger. Note that I didn't change std::experimental::bad_optional_access, because that's still specified to derive from std::logic_error.

N4100 states that an error shall be reported if
`!exists(p) || !is_directory(p)`.  We were missing the first half of the
conditional.  Invert the error and normal code paths to make the code

Eric Fiselier e49cdfbeea Recommit [libcxx] Never use <cassert> within libc++
It is my opinion that libc++ should never use `<cassert>`, including in the `dylib`.
This patch remove all uses of `assert` from within libc++ and replaces most of them with `_LIBCPP_ASSERT` instead.

Additionally this patch turn `LIBCXX_ENABLE_ASSERTIONS`  off by default,
because the standard library should not be aborting user programs unless explicitly asked to.
