Stephan T. Lavavej aae63566dc [libcxx] [test] Rename _Tp to T. NFCI.
This improves readability and (theoretically) improves portability,

Stephan T. Lavavej ba8754ab09 [libcxx] [test] Update locale names for Windows.
locale.codecvt.byname/ctor_char.pass.cpp:
This test used to use "en_US" as a plain string instead of using platform_support.
Need to fix this because MS STL expects "en-US" instead.

platform_support.h:
These are the legacy Windows locale names. Should use IETF tags instead.
I've also added en_US, since a test was using that as a locale string as well.

msvc_stdlib_force_include.hpp:
Remove _MSVC_STL_VER. The libraries will directly define _MSVC_STL_VERSION in the future.

Fixes D29351.

Mehdi Amini e9c66ad9fa Add markup for libc++ dylib availability
Libc++ is used as a system library on macOS and iOS (amongst others). In order
for users to be able to compile a binary that is intended to be deployed to an
older version of the platform, clang provides the
availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_
that can be placed on declarations to describe the lifecycle of a symbol in the
library.

See docs/DesignDocs/AvailabilityMarkup.rst for more information.

Mehdi Amini f8764e30d5 Add deployment knobs to tests (for Apple platforms)
The tests for libc++ specify -target on the command-line to the
compiler, but this is problematic for a few reasons.

Firstly, the -target option isn't supported on Apple platforms. Parts
of the triple get dropped and ignored. Instead, software should be
compiled with a combination of the -arch and -m<name>-version-min
options.

Secondly, the generic "darwin" target references a kernel version
instead of a platform version. Each platform has its own independent
versions (with different versions of libc++.1.dylib), independent of the
version of the Darwin kernel.

This commit adds support to the LIT infrastructure for testing against
Apple platforms using -arch and -platform options.

If the host is not on OS X, or the compiler type is not clang or apple-clang, then this commit has NFC.
If the host is on OS X and --param=target_triple=... is specified, then a warning is emitted to use arch and platform instead. Besides the warning, there's NFC.
If the host is on OS X and *no* target-triple is specified, then use the new deployment target logic. This uses two new lit parameters, --param=arch=<arch> and --param=platform=<platform>. <platform> has the form <name>[<version>].
By default, arch is auto-detected from clang -dumpmachine, and platform is "macosx".
If the platform doesn't have a version:
For "macosx", the version is auto-detected from the host system using sw_vers. This may give a different version than the SDK, since new SDKs can be installed on older hosts.
Otherwise, the version is auto-detected from the SDK version using xcrun --show-sdk-path.
-arch <arch> -m<name>-version-min=<version> is added to the compiler flags.
The target triple is computed as <arch>-apple-<platform>. It is *not* passed to clang, but it is available for XFAIL and UNSUPPORTED (as is with_system_cxx_lib=<target>).
For convenience, apple-darwin and <arch>-apple-darwin are added to the set of available features.
There were a number of tests marked to XFAIL on x86_64-apple-darwin11
and x86_64-apple-darwin12. I updated these to
x86_64-apple-macosx10.7 and x86_64-apple-macosx10.8.

Saleem Abdulrasool b2684a52c6 test: use char32_t rather than wchar_t
wchar_t is not as portable as char32_t.  On Windows, wchar_t is
16-bytes and on Linux 32-bits.  The conversion to utf8 causes the
characters to exceed the limits on char16_t, resulting in tautological
comparisons.

Eric Fiselier 0d542d350d [libc++] Fix support for multibyte thousands_sep and decimal_point in moneypunct_byname and numpunct_byname.
Summary:
The underlying C locales provide the `thousands_sep` and `decimal_point` as strings, possible with more than one character. We currently don't handle this case even for `wchar_t`.

This patch properly converts the mbs -> wide character for `moneypunct_byname<wchar_t>`. For the `moneypunct_byname<char>` case we attempt to narrow the WC and if that fails we also attempt to translate it to some reasonable value. For example we translate U00A0 (non-breaking space) into U0020 (regular space). If none of these conversions succeed then we simply allow the base class to provide a fallback value.

Eric Fiselier 197228927a Remove locale tests that depend on enviroment variables.
Constructing a std::locale object from an empty string selects the language
from the current environment variables. If the environment variables name
a locale that doesn't exist, or isn't installed, then the construction of
facets using that locale may throw.

This patch removes tests that use 'std::locale l("")'.

The optimal solution would be to manually set the environment variables
in the test. Unfortunately there is no portable way to do this.

The move constructor for wstring_convert accidentally copied the state member

the typo.

While working on this I discovered that wstring_convert doesn't actually
provide a move constructor according to the standard and therefore this
constructor is a libc++ extension. I'll look further into whether libc++ should
provide this constructor at all. Neither libstdc++ or MSVC's STL provide it.

Jonas Hahnfeld 83bedca7e9 [libcxx] Remove localization tests for Russian month names
Commit f49839299a085505eb673544744b61d2d9cdd1db in glibc-2.14 changed the
locales to the currently required format. However, they were again changed in
commit 55bdd2866f23b28422d969060b3518909a12b100 which has been released in 2.17.

That leads to the current situation where Debian and e.g. CentOS 6 have the
pre-2.14 locales, for example Ubuntu 14.04 has pre-2.17 and CentOS 7 on the
other hand has the newest locales in glibc-2.17.

Asiri Rathnayake ea4282d336 [libcxx] Fixup a few fumbles in the initial no-exceptions XFAILs list.
The initial buildbot run found a few missing bits in the initial XFAIL list
for the no-exceptions libc++ variant. These discrepancies are as follows:

[1] Following two tests need XFAILs on the no-exceptions library variant.
My local runs had these two disabled for other reasons (unsupported):

  - localization/locales/locale/locale.cons/char_pointer.pass.cpp
  - numerics/complex.number/complex.ops/complex_divide_complex.pass.cpp

[2] These three does not need XFAILs, they were failing on my local runs for
other reasons:

  - depr/depr.c.headers/uchar_h.pass.cpp
  - input.output/iostreams.base/ios/basic.ios.members/copyfmt.pass.cpp
  - .../category.collate/locale.collate.byname/transform.pass.cpp

(these are failing on my box for the default build as well)

The current patch fixes both the cases above. Additionally, I've run the
following scan to make sure I've covered all the cases:

> grep ' catch \| try \| throw ' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
  uniq > 1.txt
> grep 'libcpp-no-exceptions' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
  uniq > 2.txt
> diff 1.txt 2.txt

This showed up a few extra interesting cases:

[3] These two tests do not use try/catch/throw statements, but they fail at
runtime. Need to be investigated, I've left the XFAILs in.

  - std/thread/futures/futures.shared_future/dtor.pass.cpp
  - std/thread/futures/futures.unique_future/dtor.pass.cpp

[4] These tests use a macro named TEST_HAS_NO_EXCEPTIONS to conditionally
exclude try/catch/throw statements when running without exceptions. I'm not
entirely sure why this was needed (AFAIK, we didn't have a no-exceptions
library build before). The macro's defintion is quite similar to that of
_LIBCPP_NO_EXCEPTIONS. I will investigate if this can be reused for my test
fixes or if it should be replaced with _LIBCPP_NO_EXCEPTIONS.

Ed Schouten e0cf3b9a3c Make support for thread-unsafe C functions optional.
One of the aspects of CloudABI is that it aims to help you write code
that is thread-safe out of the box. This is very important if you want
to write libraries that are easy to reuse. For CloudABI we decided to
not provide the thread-unsafe functions. So far this is working out
pretty well, as thread-unsafety issues are detected really early on.

The following patch adds a knob to libc++,
_LIBCPP_HAS_NO_THREAD_UNSAFE_C_FUNCTIONS, that can be set to disable
thread-unsafe functions that can easily be avoided in practice. The
following functions are not thread-safe:

- <clocale>: locale handles should be preferred over setlocale().
- <cstdlib>: mbrlen(), mbrtowc() and wcrtomb() should be preferred over
  their non-restartable counterparts.
- <ctime>: asctime(), ctime(), gmtime() and localtime() are not
  thread-safe. The first two are also deprecated by POSIX.
