Summary:
This allows the linker script generation to query CMake properties
(specifically the dependencies of libc++.so) instead of having to
carry these dependencies around manually in global variables. Notice
the removal of the LIBCXX_INTERFACE_LIBRARIES global variable.

It turns out that r374056 broke _some_ build bots again, specifically
the ones using sanitizers. Instead of trying to link the right system
libraries to the benchmarks bit-by-bit, let's just link exactly the
system libraries that libc++ itself needs.

We tried doing that previously (in r373487) and failed (reverted in
r373506) because the benchmarks needed to link against system libraries
and relied on libc++'s dependencies being propagated. Now that this has
been fixed (in r374053), this commit marks the system libraries as
PRIVATE dependencies of libc++.

Since the benchmarks build with -nostdlib, they need to manually link
against some system libraries that are used by the benchmarks and the
GoogleBenchmark library itself.
Previously, we'd rely on the fact that these libraries were linked
through the PUBLIC dependencies of cxx_shared/cxx_static. However,
if we were to make these dependencies PRIVATE (as they should be
because they are implementation details of libc++), the benchmarks
would fail to link. This commit remediates that.

It's better style to use PRIVATE when linking libraries to executables,
and it doesn't make a difference since executables don't need to propagate
their link-time dependencies anyway.

Summary: In my last patch (D67675) I forgot a few variadics. This patch removes the remaining make_shared and allocate_shared C++03 variadics.

If you explicitly set LIBCXX_ENABLE_EXPERIMENTAL_LIBRARY to OFF, your
project will fail to configure because the cxx_experimental target
doesn't exist.

Also, set those flags for the cxx_experimental target. Otherwise,
cxx_experimental doesn't build properly when neither the static nor
the shared library is compiled (yes, that is a weird setup).

Summary:
The current version of the pretty printers are not python3 compatible,
so turn them off by default until sufficiently improved.

It appears that those need to be propagated to targets that use libc++
as well, otherwise they don't build properly.

The first commit removed the workaround in a old script.
This patch removes it in the file actually used by the bots.
I have no idea if this is still needed, but removing the
workaround seems like the easiest way to test.
I'll revert this change if the bots go red.

This allows propagating the include automatically to targets that
depend on one of the libc++ targets such as the benchmarks. Note
that the GoogleBenchmark build itself still needs to manually specify
the -include, since I don't know of any way to have an external project
link against one of the libc++ targets (which would propagate the -include
automatically).

In both Python 2 and Python 3, gdb.Value.string returns a 'str'. We just
need to delete a `encode("utf-8")` which would return a 'bytes' in
Python 3.

This commit follows the trend of doing things per-target instead of
modifying the C++ flags globally. It does so for visibility-related
flags, other basic build flags and Windows-specific flags.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@373517 91177308-0d34-0410-b5e6-96231b3b80d8
This is part of a larger shift to move to per-target settings and
eradicate global variables from the CMake build. I'm starting small
with warnings only because those are easy to transition over and I
want to see how it pans out, but we can handle all flags like exceptions
and RTTI in the future.

It turns out the benchmarks need to link against those libraries
explicitly too, so CMake's propagation of PUBLIC dependencies is
used.

Summary:
I haven't managed a small reproduction for this bug, it involves
complicated and deeply nested data structures with a wide variety
of pretty printers. But in general, we shouldn't be combining
gdb's command line interface (via gdb.execute) with pretty-printers.

In reality, this workaround is for the fact that LIBCXX_CXX_ABI=libcxxabi
can't be specified on Linux, since libc++abi isn't shipped with the system.
Since the build bots explicitly specify LIBCXX_CXX_ABI=libcxxabi, they fail
unless we apply the workaround.

I tried applying D63883 three times and could never get around to
making it work. I'm giving up on that for now, but soon this should
be irrelevant anyway since all builds will move to the monorepo
(where we're always using the in-tree libc++abi unless explicitly
specified otherwise).

Summary:
LWG 3158 marks the allocator_arg_t constructor of std::tuple as
conditionnally explicit based on whether the default constructors
of the tuple's members are explicitly default constructible.
This was previously committed as r372778 and reverted in r372832 due to
the commit breaking LLVM's build in C++14 mode. This issue has now been
addressed.

for the pair/tuple's elements.

Users should only get the assert() macros if they explicitly include

We don't support GCC 4 and older according to the documentation, so
we should pretend it doesn't exist.

synopsis. Users are still required to include <ostream> to get the
definition of the streaming operator.
