9b36c1cf27 Determine endianness at a time when it doesn't inadvertantly clear gdb's wrap_buffer via gdb.execute.
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.

3270941f1e Add gdb pretty printers for a wide variety of libc++ data structures (take 2).
Summary:
This patch is an exact duplicate of https://reviews.llvm.org/D65609, except
that it uses the newly introduced testing framework to detect if gdb is present
so that the tests won't fail on machines without gdb.

344eee9227 [libc++] Improve Python 3 compatibility for merge_archives.py
Popen.communicate() method in Python 2 returns a pair of strings, and in
Python 3 it returns a pair of byte-like objects unless universal_newlines

merge_archives.py works fine with Python 3.

5f92cb7014 [libc++] Fix environment variable passing in libc++'s SSHExecutor lit utility
Summary:
Quote the value of environment variables when passing them to the SSH
client in SSHExecutor in libc++'s lit utilities. Without the quotes,
an environment variable like FOO="buzz bar" gets passed incorrectly
like this, ssh env FOO=buzz bar, which causes bar to be treated as a
command to run, not part of the environment variable value.

We ran into this when using SSHExecutor to do bringup of our CUDA
libcu++ port on an embedded aarch64 system.

bf4808439f [pstl] Add a __pstl_config_site header to record the CMake configuration
This commit adds a __pstl_config_site header that contains the value of
macros specified at CMake configuration time. It works similarly to
libc++'s __config_site header, except we always include it as a separate
file instead of concatenating it to the main configuration header.

It is necessary to thread the includes for that header into libc++'s
lit configuration, otherwise we'd be requiring an installation step
prior to running the test suite.

0a06eb911b [libc++] Take 2: Integrate the PSTL into libc++
Summary:
This commit allows specifying LIBCXX_ENABLE_PARALLEL_ALGORITHMS when
configuring libc++ in CMake. When that option is enabled, libc++ will
assume that the PSTL can be found somewhere on the CMake module path,
and it will provide the C++17 parallel algorithms based on the PSTL
(that is assumed to be available).

The commit also adds support for running the PSTL tests as part of
the libc++ test suite.

The first attempt to commit this failed because it exposed a bug in the
tests for modules. Now that this has been fixed, it should be safe to
commit this.

0c045f135d Ensure __config_site definitions are passed to modules tests.
The test configuration contained a bug where we only raised
the __config_site commands to the command line if modules were

modules-only tests, and these tests weren't getting the correct
defines.

This patch corrects that issue.

b9179ff857 [AIX][lit] Don't depend on psutil on AIX
Summary:
On AIX psutil can run into problems with permissions to read the process
tree, which causes problems for python timeout tests which need to kill off
a test and it's children.

This patch adds a workaround by invoking shell via subprocess and using a
platform specific option to ps to list all the descendant processes so we can
kill them. We add some checks so lit can tell whether timeout tests are
supported with out exposing whether we are utilizing the psutil
implementation or the alternative.

c3e452acde [libc++] Do not infer support for C++17 in GCC < 7
libc++'s lit configuration infers the C++ language dialect when it is
not provided by checking which -std= flags that a compiler supports.
GCC 5 and GCC 6 have a -std=c++17 flag, however, they do not have full
C++17 support. The lit configuration has hardcoded logic that removes
-std=c++1z as an option to test for GCC < 7, but not -std=c++17.

This leads to a bunch of failures when running libc++ tests with GCC 5
or GCC 6. This patch adds -std=c++17 to the list of flags that are
discarded for GCC < 7 by lit's language dialect inference.

Thanks to Bryce Adelstein Lelbach for the patch.

a5bb7b6c20 [libcxx] [test] Read files as bytestrings to fix py3 encoding issues
Use binary mode to read test files in libcxx LibcxxTestFormat class.
This ensures that tests are read correctly independently of encoding,
and therefore fixes UnicodeDecodeError when file is opened in Python 3
that defaults to pure ASCII encoding.

Technically this could be also fixed via conditionally appending
encoding argument when opening the file in Python 3.  However, since
the code in question only searches for fixed ASCII substrings reading
it in binary mode is simpler and more universal.

Summary:
Ensure we re-export __cxa_throw_bad_array_new_length and
__cxa_uncaught_exceptions from libc++, since they are now
provided by libc++abi.

Doing this allows us to stop linking explicitly against libc++abi in
the libc++abi tests, since libc++ re-exports all the necessary symbols.
However, there is one caveat to that. We don't want libc++ to re-export
__cxa_uncaught_exception (the singular form), since it's only provided
for backwards compatibility. Hence, for the single test where we check
this backwards compatibility, we explicitly link against libc++abi.
