Stephan T. Lavavej bc933768a6 [libcxx] [test] Update for C++17 feature removals.
test/std/containers/Emplaceable.h
test/std/containers/NotConstructible.h

test/std/depr/depr.function.objects/depr.base/unary_function.pass.cpp
test/std/utilities/function.objects/func.require/binary_function.pass.cpp
test/std/utilities/function.objects/func.require/unary_function.pass.cpp
Mark these tests as requiring 98/03/11/14 because 17 removed unary_function/binary_function.

test/std/thread/futures/futures.task/futures.task.members/ctor_func_alloc.pass.cpp
test/std/thread/futures/futures.task/futures.task.nonmembers/uses_allocator.pass.cpp
Mark these tests as requiring 11/14 because 17 removed packaged_task allocator support.

test/std/utilities/function.objects/func.wrap/func.wrap.func/derive_from.pass.cpp
This test doesn't need to be skipped in C++17 mode. Only the construction of
std::function from an allocator needs to be skipped in C++17 mode.

test/std/utilities/function.objects/refwrap/refwrap.access/conversion.pass.cpp
test/std/utilities/function.objects/refwrap/refwrap.assign/copy_assign.pass.cpp
test/std/utilities/function.objects/refwrap/refwrap.const/copy_ctor.pass.cpp
test/std/utilities/function.objects/refwrap/refwrap.const/type_ctor.pass.cpp
When testing these reference_wrapper features, unary_function inheritance is totally irrelevant.

test/std/utilities/function.objects/refwrap/weak_result.pass.cpp
Define and use my_unary_function/my_binary_function to test the weak result type machinery
(which is still present in C++17, although deprecated).

test/support/msvc_stdlib_force_include.hpp
Now we can test C++17 strictly, without enabling removed features.

Fixes D36503.

Shoaib Meenai 191b7d18f1 [libc++] Hoist extern template above first use
This function template is referenced inside class basic_string as a
friend function. The extern template declaration needs to be above that
friend declaration to actually take effect.

This is important because this function was marked as exported in
r307966, so without the extern template taking effect, it can leak into
other DSOs as a visible symbol.

Shoaib Meenai 316a3e572e [libc++] Clean up cl warning 4231 disabling
Once upon a time, extern templates used to be a Microsoft extension, so

Shoaib Meenai 5b67cd3567 [libc++] Mark string operator+ _LIBCPP_FUNC_VIS
It has an extern template instantiation declaration in the headers and a

This doesn't cause any ABI changes as-is since we don't build libc++
with hidden visibility (so the function is exported anyway). It's needed
for building libc++ with hidden visibility, however.

Clarify the Windows behavior for extern function templates while I'm
here, since this exercises that behavior.

Eric Fiselier e3e7c0fb37 Remove <__refstring> header; Move it into source directory.
The libc++ <__refstring> headers has no real reason why it should
be a public header that libc++ ships. The only reason it was in the include
directory was because libc++abi needed it to build the library.

However keeping <__refstring> a header had other problems, like requiring its
dependancies to also be in the headers. For that reason this patch
moves it into the source directory.

To work around libc++abi's need for this header a duplicated copy was added
to libc++abi in r307748. While duplicating the code is an unfortunate solution
it's the best solution that's currently possible.

In the future I would like to start a discussion on the mailing lists about
making libc++abi build as a sub-project of libc++, requiring the libc++ sources
always be present.

Eric Fiselier 433c2f0859 Fix filesystem build on platforms with weird time_t types.
32-bit powerpc provides a 64 bit time_t type and older ppc64 systems
provide time_t as a floating point type. This caused problems when building
operations.cpp since operations.cpp contained compile time tests for conversions
between time_t and filesystem time type.

When these tests failed they caused the libc++ build to fail as well. This is unfortunate.

This patch moves the tests out of the source file and into the test suite. It also
expands the tests to allow testing of the weird time_t configurations on all platforms.

Eric Fiselier 635430895a Add dummy CMake target for *.pass.cpp tests when LIBCXX_CONFIGURE_IDE=ON.
In order for IDE's like CLion to correctly parse and highlight the tests
it needs to know roughly how to build them. This patch adds a dummy CMake target
for each/all of the .pass.cpp tests in the test suite to solve this problem.
The target is only created when LIBCXX_CONFIGURE_IDE=ON, so it shouldn't affect
most users.

Originally I wasn't sure that this change deserved to live upstream, but it's
quite frustrating to edit libc++ tests using CLion or Visual Studio without it,

Eric Fiselier 459877388b Implement LWG 2937 - equivalent("dne", "exists") is not an error
This patch speculatively implements the PR for LWG 2937, which fixes
two issues with equivalent.

(1) It makes equivalent("dne", "exists") an error. Previously only
    equivalent("dne", "dne") was an error and the former case was not (it returned false).
    Now equivalent reports an error when either input doesn't exist.

(2) It makes equivalent(p1, p2) well-formed when `is_other(p1) && is_other(p2)`.
    Previously this was an error, but there is seemingly no reason why it should be on POSIX system.

This reverts commit r306310.

r306310 causes clang to reject a call to an aligned allocation or
deallocation function if it is not implemented in the standard library
of the deployment target. This is not the desired behavior when users
have defined their own aligned functions.

Shoaib Meenai 8e07cadde0 [libc++] Hoist explicit instantiation above implicit. NFC
The string literal operators have implicit instantiations of
basic_string<char> and basic_string<wchar>, which prevent the dllimport
on the subsequent explicit instantiation declarations from having an
effect. Hoisting the explicit instantiations above the implicit ones
fixes the issue.

I think it's pretty unfortunate that the ordering has such an effect,
and I'd fixed the same issue for dllexport in r288682. dllimport is more
complicated from a codegen perspective, however, and clang's behavior of
ignoring the dllimport when there's a previous implicit instantiation is
consistent with cl, so changing the order is our only recourse.

Clang and C1XX both complain about mismatched class/struct, but libc++ and MSVC's STL

Style/paranoia: 42.1 doesn't have an exact binary representation. Although this doesn't
cause failures, it makes me uncomfortable, so I'm changing it to 42.5.

C1XX rightly warns about unreferenced variables. Adding tests for their values
makes C1XX happy and improves test coverage.

C1XX (somewhat obnoxiously) warns about seeing a struct specialized as a class.
Although the Standard doesn't care, saying struct consistently is better.
(The Standard itself is still inconsistent about whether to depict tuple_element
and tuple_size as structs or classes.)

Newlib 2.5 added the locale management functions, so it should not

include statement.

For newlib 2.4, some releases contain these functions and some don't,
and they all have the same version numbers. This patch will work
properly with the initial "2.4.0" release which does not include these
functions and require __nop_local_mgmt.h.

This has been tested against newlib 2.2 and 2.5, and also sanity
checks against other different version numbers.

Eric Fiselier 8551d0e319 Fix compile error with Bionic's PTHREAD_MUTEX_INITIALIZER
On Bionic PTHREAD_MUTEX_INITIALIZER contains the expression "<enum-type> & <integer-type>",
which causes ADL to perform name lookup for operator&. During this lookup Clang decides
that it requires the default member initializer for std::mutex while defining the DMI
for std::mutex::__m_.

If I'm not mistaken this is caused by the explicit noexcept declaration on the defaulted
constructor.

This patch removes the explicit noexcept and instead allows the compiler to declare
the default constructor implicitly noexcept. It also adds a static_assert to ensure
that happens.

Unfortunatly because it's not easy to change the value of _LIBCPP_MUTEX_INITIALIZER
for a single test there is no good way to test this patch.

The Clang behavior causing the trouble here was introduced in r287713, which first
appears in the 4.0 release.

Eric Fiselier a016efb1dc [Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows
Summary:
This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning.
This patch changes libc++ to use `#pragma push_macro`  to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.

Eric Fiselier 3fd0228ead [coroutines] Make coroutine_handle<T>::from_address ill-formed for everything but void*.
from_address requires that the provided pointer refer to the suspended coroutine,
which doesn't have a type, or at least not one knowable by the user. Therefore
every use of `from_address` with a typed pointer is almost certainly a bug.

This behavior is a part of the TS specification, but hopefully it will be
in the future.

Eric Fiselier c34a497b40 [coroutines] Add end-to-end tests within libc++
This patch adds end-to-end/breathing tests for coroutines
into libc++. The tests aren't specifically to test libc++ requirements
but instead are intented to ensure coroutines are working fine in general.

Although libc++ isn't exactly the most correct place for these tests
to live, there is one major advantage. The libc++ test suite is also
used by MSVC and by adding the tests here it ensures they will be
run against all currently available coroutine implementations.

Eric Fiselier 997a391466 Get <experimental/coroutine> working in C++03.
Clang supports coroutines in all dialects; Therefore libc++ should too,
otherwise the Clang extension is unusable.

I'm not convinced extending support to C++03 is a feasible long term
plan, since as the library grows to offer things like generators it
will be come increasingly difficult to limit the implementation to C++03.

However for the time being supporting C++03 isn't a big deal.

Eric Fiselier eb04c8cae2 Guard <experimental/coroutine> against older Clang versions.
Clang started providing -fcoroutines and defining __cpp_coroutines
way before it implemented the __builtin_coro_foo functions. This
means that simply checking if __cpp_coroutines is not a sufficient
way of detecting the actual feature.

This patch implements _LIBCPP_HAS_NO_COROUTINES which implements
a slightly more complex feature check. Specifically it requires
__cpp_coroutines >= 201703L, which only holds for Clang 5.0 built
after 2017/05/24.

Eric Fiselier abaf967ceb Remove incorrect #ifdef guards around variant tests.
The tests were previously guarded by #if defined(_LIBCPP_VER) || defined(_MSVC_STL_VER),
which is both incorrect (e.g. _LIBCPP_VERSION) and unneeded. Although the tests are
technically non-standard (yet) they are supported by both libc++ and MSVC's STL.

libstdc++ doesn't regularly use the test suite so I'm not concerned about guarding these
tests for them.

Eric Fiselier ea96891fb4 Re-add <experimental/coroutine> to the module map.
The original issues were caused because <experimental/coroutine>
didn't correctly #ifdef out enough of the header, which caused incomplete
types to be used.

This patch fixes the `#if defined(__cpp_coroutines)` guard and re-adds
the headers to the module map.

It also uglifies some incorrectly non-reserved names.
