Petr Hosek bfb371a083 [CMake] Check runtimes subdir when looking for libcxx and libuwind
The runtimes subdir is the new location for runtimes, we should
include it when looking for libcxx and libunwind headers.

Mehdi Amini 7b9e9f2857 Add some facilities to work with a git monorepo (experimental setup)
Summary:
Some changes are made to cmake, especially the addition of a new
LLVM_ENABLE_PROJECTS option that makes the build system aware of
the monorepo directory structure.

Also a new script is added in llvm/utils/git-svn/. When present in
the $PATH, it enables a `git llvm` command. It is providing at this
point only the ability to push from the git monorepo: `git llvm push`.
It is intended to evolves with more features, for instance I plan on
features like `git llvm show r284955` to help working with sequential
revision numbers.
The push feature is taken from Justin Lebar's script available here:

Richard Smith 80b64f0861 [p0012] Implement ABI support for throwing a noexcept function pointer and

This implements the following proposal from cxx-abi-dev:

http://sourcerytools.com/pipermail/cxx-abi-dev/2016-October/002988.html

... which is necessary for complete support of http://wg21.link/p0012,
specifically throwing noexcept function and member function pointers and
catching them as non-noexcept pointers.

This patch refactors all pthread uses of libc++abi into a separate API. This

I've followed the conventions already used in the libc++ library for the same

Igor Kudrin d9edde4ae2 Recommit r282692: [libc++abi] Use fallback_malloc to allocate __cxa_eh_globals in case of dynamic memory exhaustion.
Throwing an exception for the first time may lead to call calloc to
allocate memory for __cxa_eh_globals. If the memory pool is exhausted
at that moment, it results in abnormal termination of the program.

This patch addresses the issue by using fallback_malloc in that case.

In this revision, some restrictions were added into the test to not
run it in unsuitable environments.

Eric Fiselier 36ca35f505 [CMake] Be more consistent about naming targets and components in libc++abi
This patch (and commit summary) mirror r279675 by Chris B which was applied
to libc++ but not libc++abi.

Summary:
The point of this patch is to have a consistent convention for naming build,
check and install targets so that the targets can be constructed from the
project name.

This change renames a bunch of CMake components and targets from libcxxabi to
cxxabi. For each renamed target I've added a convenience target that matches
the old target name and depends on the new target. This will preserve function
of the old targets so that the change doesn't break the world. We can evaluate
if it is worth removing the extra targets later.

Saleem Abdulrasool 0b7b36a9dd test: fix test under ASAN and MSAN
When we're running tests under ASAN or MSAN, they're compiled with -O1, which
enables tail call elimination. This causes backtrace_test to fail: the compiler
performs tail call elimination for call3_nothrow, but it can't for call3_throw,
leading to a mismatched frame count. Disable tail call elimination (and
inlining, just to be explicit) to avoid this.

Richard Smith 2f984cab4f [libcxxabi] When catching an exception of type nullptr_t with a handler of
pointer-to-member type, produce a null value of the right type.

This fixes a bug where throwing an exception of type nullptr_t and catching it
as a pointer-to-member would not guarantee to produce a null value in the catch
handler. The fix is pretty simple: we statically allocate a constant null
pointer-to-data-member representation and a constant null
pointer-to-member-function representation, and produce the address of the
relevant value as the adjusted pointer for the exception.

However the test notes that it is checking that "virtual base classes work properly". Since initialization order is clearly part of correctness I want to confirm that this wasn't an intentional mistake.
