Zachary Turner 2878bf44b1 [Windows] XFAIL tests that depend on expression name lookup.
Name lookup doesn't work properly with Windows targets.  This is
most likely due to issues with name mangling, although there is at
least one set of debug info related issues as well, since some of
the name lookup requests appear to be failing on types rather than
symbols.

Specifically, this patch XFAILS the following set of tests:

TestChar1632T.py
TestRdar12991846.py
TestConstVariables.py
TestCallCPPFunction.py
TestCallStopAndContinue.py

Eric Fiselier 0d28f78401 [libcxx] Fix PR23589: std::function doesn't recognize null pointer to varargs function.
Summary:
This patch fixes __not_null's detection of nullptr by breaking it down into 4 cases.

1. `__not_null(Tp const&)`: Default case. Tp is not null.
2. `__not_null(Tp* __ptr);` Case for pointers to functions.
3. `__not_null(_Ret _Class::* __ptr);` Case for pointers to members.
4. `__not_null(function<Tp> const&);`: Cases for other std::functions.

Eric Fiselier 4504cf2c8d [libc++] Fix PR22606 - Leak pthread_key with static storage duration to ensure all of thread-local destructors are called.
Summary:
See https://llvm.org/bugs/show_bug.cgi?id=22606 for more discussion.

Most of the changes in this patch are file reorganization to help ensure assumptions about how __thread_specific_pointer is used hold. The assumptions are:

* `__thread_specific_ptr<Tp>` is only created with a `__thread_struct` pointer.
* `__thread_specific_ptr<Tp>` can only be constructed inside the `__thread_local_data()` function.

I'll remove the comments before committing. They are there for clarity during review.

Eric Fiselier 556f9340f7 [libcxx] Disable -Wnon-virtual-dtor warning in <locale>
Summary:
Normally people won't see warnings in libc++ headers, but if they compile with "-Wsystem-headers -Wnon-virtual-dtor" they will likely see issues in <locale>.

In the libc++ implementation `time_get' has a private base class, `__time_get_c_storage`, with virtual methods but a non-virtual destructor. 
`time_get` itself can safely be used as a polymorphic base class because it inherits a virtual destructor from `locale::facet`. To placate the compiler we change `__time_get_c_storage`'s destructor from public to protected, ensuring that it will never be deleted polymorphically.

George Burgess IV 232c76213d Make __builtin_object_size always answer correctly
__builtin_object_size would return incorrect answers for many uses where
type=3. This fixes the inaccuracy by making us emit 0 instead of LLVM's
objectsize intrinsic.

Additionally, there are many cases where we would emit suboptimal (but
correct) answers, such as when arrays are involved. This patch fixes
some of these cases (please see new tests in test/CodeGen/object-size.c
for specifics on which cases are improved)

Chandler Carruth 7adc3a2b0e [PM/AA] Remove the last relics of the separate IPA library from LLVM,
folding the code into the main Analysis library.

There already wasn't much of a distinction between Analysis and IPA.
A number of the passes in Analysis are actually IPA passes, and there
doesn't seem to be any advantage to separating them.

Moreover, it makes it hard to have interactions between analyses that
are both local and interprocedural. In trying to make the Alias Analysis
infrastructure work with the new pass manager, it becomes particularly
awkward to navigate this split.

I've tried to find all the places where we referenced this, but I may
have missed some. I have also adjusted the C API to continue to be
equivalently functional after this change.

Tobias Grosser cf9ebb63d6 Use schedule trees to compute dependences
This patch changes Polly to compute the data-dependences on the schedule tree
instead of a flat schedule representation. Calculating dependences directly on
the schedule tree results in some good compile-time improvements (adi : -23.35%,
3mm : -9.57%), as the structure of the schedule can be exploited for increased
efficiency.

Earlier experiments with schedule tree based dependence analysis in Polly showed
some compile-time regressions. These regressions arose due to the schedule tree
based dependence analysis not taking into account the domain constraints of the
schedule tree. As a result, the computed dependences were different and this
difference caused in some cases the schedule optimizer to take a very long time.
Since isl version fe865996 the schedule tree based dependence analysis takes
domain constraints into account, which fixes the earlier compile-time issues.

Sergey Dmitrouk d5a00e8e3c [compiler-rt] Add AArch64 to CMake configuration and several missing builtins
Summary:
Currently CMake doesn't build builtins for AArch64 and if one does this anyway
it's likely that at least `__multc3`, `__floatditf` and `__floatunditf` will be
missing.  There is actually more builtins to add, but these come from
different libc implementations, thus providing them makes compiler-rt for
AArch64 good enough at least for basic usage.

Builtins implementation were originally taken from FreeBSD project:

 * [[ https://reviews.freebsd.org/D2173 | __multc3 ]]
 * [[ https://reviews.freebsd.org/D2174 | __floatditf and __floatunditf ]]

Until they have been tested to find mistakes in `__float*` functions.
`__floatditf` was based on `__floatsitf`, which had the same mistakes
(fixed it in r243746).

Version of the builtins in this patch are fixed and complemented with basic
tests.  Additionally they were tested via GCC's torture (this is what revealed
these issues).

P.S. Ed (author of FreeBSD patches) asked for feedback on the list some time ago (here [[ http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/084064.html | here ]])
and got no response, but it seems to be worth adding these builtins as is and
extracting common part later.

By making this information available to the MipsAsmParser, we will know when to insert the instructions mandated by the .cprestore assembler directive and we will be able to give some useful warnings when we encounter a potential misuse of this directive.
