Billy Robert O'Neal III 362ea7329f Fix possible loss of data warnings on amd64
In T_size_size.pass, there is an explicit template argument to std::min to ask
for unsigned, to avoid type deduction errors. However, C1XX' warnings still
hate this use, because a 64 bit value (a size_t) is being passed to a function
accepting an unsigned (a 32 bit value).

Instead, change the tests to pass around std::size_t instances, and explicitly
narrow when constructing the string type under test. This also allows
removal of explicit template arguments to std::min.

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.

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 38590b3845 Fix std::string assignment ambiguity from braced initializer lists.
When support for `basic_string_view` was added to string it also
added new assignment operators from `basic_string_view`. These caused
ambiguity when assigning from a braced initializer. This patch fixes
that regression by making the basic_string_view assignment operator
rank lower in overload resolution by making it a template.
