Renato Golin 9e737939fb [libc++abi] Allow use just compiled clang++ for tests
Currently, the tests assume the system compiler is the one we want
to test, but if we build libcxxabi together with LLVM+Clang, it'll
get the wrong compiler.

This patch allows us to test if we have clang++ in our /bin directory,
and if so, use it.

Eric Fiselier 753f7c306b [libcxxabi] Teach CMake better ways to find the libc++ source directory (and misc cleanup).
Summary:
The main section of this patch teaches CMake  a new option `LIBCXXABI_LIBCXX_PATH` that specifies the path to the libcxx source root. This information is passed to lit so that it can better find libc++'s python module. `LIBCXXABI_LIBCXX_PATH` is also used to help find the libc++ headers.

The rest of this patch is misc cleanup, mostly to make pep8 and pylint happy.
I've also copied libc++'s .gitignore into libc++abi.

Chandler Carruth 24a6b05680 [cmake/multilib] Teach libc++abi's CMake build to support multilib
libdir suffixes like 'lib64' or 'lib32'.

This support is currently very rhudimentary. We define a variable
LIBCXXABI_LIBDIR_SUFFIX. In a standalone build of libc++abi this can be
directly set as a cached variable to control the multilib suffix used.
When building libc++abi within a larger LLVM build, it is hard wired to
whatever LLVM libdir suffix has been selected. If this doesn't work for
someone, just let me know. I'm happy to change it.

Unfortunately, libc++abi's lit setup made this somewhat problematic to
change. It was setting variables up in a way that caused the resulting
build to not work with lit at all. To fix that, I've moved some
variables around in the CMake build to more closely match where and how
they are defined in the libc++ CMake build. This includes specifically
defining a library root variable in the CMake build where the libdir
suffix can be applied, and then using that rather than re-computing it
from the object directory in the lit config.

This is essentially new functionality for libc++abi so I don't expect it
to have any impact for folks until they start setting these variables.
However, I know libc++abi is built in a diverse set of environments so
just let me know if this causes you any problems.

Dan Albert 12c0c8b67f [libcxxabi] Add __cxa_thread_atexit for TLS support on Linux.
Summary:
Fixes PR21738.

The implementation for this is handled by __cxa_thread_atexit_impl,
which is supplied by libc.

Eric Fiselier 559f867af2 [libcxxabi] Refactor building and testing libc++abi without threads
Summary:
This patch adds CMake support for building and testing libc++abi without threads. 


1. Add `LIBCXXABI_ENABLE_THREADS` option to CMake.
2. Propagate `LIBCXXABI_ENABLE_THREADS` to lit via lit.site.cfg.in
3. Configure tests for `LIBCXXABI_ENABLE_THREADS=OFF

Currently the test suite does not work when libc++abi is built without threads because that information does not propagate to the test suite.

Eric Fiselier c5de7b113b [libcxxabi] Refactor test timing logic and disable by default.
Summary:
When using LIT the timing output is entirely unused but introduces a dependency on `<chrono>`. When libc++ is built without a montonic clock this causes some of the tests to fail.
This patch factors out all of the timing logic into `support/timer.hpp` and disables it by default. To enable the timing you must define `LIBCXXABI_TIME_TESTS`.

Although the current method is valid up till python 3.3 (which is not supported)
this seems to be a clearer way of checking for linux and moves the tests towards
python 3 compatibility.

Dan Albert a770f9d66b Add lit configs for libcxxabi tests.
This makes running libcxxabi tests on Linux _much_ easier.
Adds a check-libcxxabi target to cmake.

Also defaults to building a dynamic libc++abi. This is so that the
default options still test the libc++abi that is being built. There are
two problems with testing a static libc++abi. In the case of a
standalone build, the tests will link the system's libc++, which might
not have been built against our libc++abi. In the case of an in tree
build, libc++ will prefer a dynamic libc++abi from the system over a
static libc++abi from the output directory.
