David Majnemer 1878da43ea [CodeGen] Provide an appropriate alignment for dynamic allocas
GCC documents __builtin_alloca as aligning the storage to at least
__BIGGEST_ALIGNMENT__.

MSVC documents essentially the same for the x64 ABI:
https://msdn.microsoft.com/en-us/library/x9sx5da1.aspx

The 32-bit ABI follows the same rule: it emits a call to _alloca_probe_16

David Majnemer 07c915e1d5 [MS ABI] Reuse getVFPtrOffsets instead of using getClassAtVTableLocation
getClassAtVTableLocation hunts through virtual bases without using the
MDC layout which is indicative of a bug.

Instead, reuse the getVFPtrOffsets machinery to calculate which
subobject within the MDC is responsible for the vfptr.

Samuel Antao 28c4f18bfe [Driver][OpenMP] Add specialized action builder for OpenMP offloading actions.
Summary:
This patch adds a new specialized action builder to create OpenMP offloading actions. The specialized builder is added to the action builder already containing the CUDA specialized builder.

OpenMP offloading dependences between host and device actions (expressed with OffloadActions) are different that what is used for CUDA:
 - Device compile action depends on the host compile action - the device frontend extracts the information about the declarations that have to be emitted by looking into the metadata produced by the host frontend.
 - The host link action depends on the device link actions - the device images are embedded in the host binary at link time.

Nico Weber 44f6f2ee42 Expand -Wlogical-not-parentheses to also fire on `!x & A`.
This is a misspelling of the intended !(x & A) negated bit test that happens in
practice every now and then.

I ran this on Chromium and all its dependencies, and it fired 0 times -- no
false or true positives, but it would've caught a bug in an in-progress change
that had to be caught by a Visual Studio warning instead.

Samuel Antao 9c9d9cdcf8 [Driver][CUDA][OpenMP] Reimplement tool selection in the driver.
Summary:
This creates a tool selector in the driver that replaces the existing one. The goal is to better organize the code and make the selector easier to scale, in particular in the presence of offload actions that can be collapsed. 

The current implementation became more confusing when the support for offloading actions was added. This concern was expressed by Eric in http://reviews.llvm.org/D9888.

This patch does not add new testing, it preserves the existing functionality.

Erik Verbruggen 52b26713be Mark invalid RecordDecls as completed.
Sema::ActOnTag creates TagDecls for records. However, if those record
declarations are invalid, and the parser is in C++ mode, it would
silently drop the TagDecl (and leave it as "beingDefined"). The problem
is that other code (e.g. the ASTWriter) will serialize all types, and
expects them to be complete. So, leaving them open would result in
failing asserts.

Eric Fiselier 709d1b30ab [coroutines] Build fallthrough and set_exception statements.
Summary:
This patch adds semantic checking and building of the fall-through `co_return;` statement as well as the `p.set_exception(std::current_exception())` call for handling uncaught exceptions.

The fall-through statement is built and checked according to:
> [dcl.fct.def.coroutine]/4
> The unqualified-ids return_void and return_value are looked up in the scope of class P. If
> both are found, the program is ill-formed. If the unqualified-id return_void is found, flowing
> off the end of a coroutine is equivalent to a co_return with no operand. Otherwise, flowing off
> the end of a coroutine results in undefined behavior.

Similarly the `set_exception` call is only built when that unqualified-id is found in the scope of class P.

Additionally this patch adds fall-through warnings for non-void returning coroutines. Since it's surprising undefined behavior I thought it would be important to add the warning right away.

Vitaly Buka 64c80b4e39 [CodeGen] Don't emit lifetime intrinsics for some local variables
Summary:
Current generation of lifetime intrinsics does not handle cases like:

```
  {
    char x;
  l1:
    bar(&x, 1);
  }
  goto l1;

```
We will get code like this:

```
  %x = alloca i8, align 1
  call void @llvm.lifetime.start(i64 1, i8* nonnull %x)
  br label %l1
l1:
  %call = call i32 @bar(i8* nonnull %x, i32 1)
  call void @llvm.lifetime.end(i64 1, i8* nonnull %x)
  br label %l1
```

So the second time bar was called for x which is marked as dead.
Lifetime markers here are misleading so it's better to remove them at all.
This type of bypasses are rare, e.g. code detects just 8 functions building
clang (2329 targets).

Richard Smith fda59e5851 Implement name mangling proposal for exception specifications from cxx-abi-dev 2016-10-11.
This has the following ABI impact:

 1) Functions whose parameter or return types are non-throwing function pointer
    types have different manglings in c++1z mode from prior modes. This is
    necessary because c++1z permits overloading on the noexceptness of function
    pointer parameter types. A warning is issued for cases that will change
    manglings in c++1z mode.

 2) Functions whose parameter or return types contain instantiation-dependent
    exception specifications change manglings in all modes. This is necessary
    to support overloading on / SFINAE in these exception specifications, which
    a careful reading of the standard indicates has essentially always been
    permitted.

Note that, in order to be affected by these changes, the code in question must
specify an exception specification on a function pointer/reference type that is
written syntactically within the declaration of another function. Such
declarations are very rare, and I have so far been unable to find any code
that would be affected by this. (Note that such things will probably become
more common in C++17, since it's a lot easier to get a noexcept function type
as a function parameter / return type there.)

This change does not affect the set of symbols produced by a build of clang,
libc++, or libc++abi.

Committed after LGTM and check-all

 
Vector-reduction arithmetic accepts vectors as inputs and produces scalars as outputs.
This class of vector operation forms the basis of many scientific computations.
In vector-reduction arithmetic, the evaluation off is independent of the order of the input elements of V.
 
Used bisection method. At each step, we partition the vector with previous
step in half, and the operation is performed on its two halves.
This takes log2(n) steps where n is the number of elements in the vector.

These new builtins support a mechanism for logging OS events, using a

The _buffer_size version of the builtin can be used to determine the size
of the buffer to allocate to hold the data, and then __builtin_os_log_format
can write data into that buffer. This implements format checking to report
mismatches between the format string and the data arguments. Most of this

This commit fixes an invalid Winitializer-overrides warning that's shown
when analyzing a second (or any after the first) instantiation of a designated
initializer. This invalid warning is fixed by making sure that a
DesignatedInitExpr is rebuilt by the tree transformer when it has a field
designator whose FieldDecl* hasn't been yet initialized. This ensures that a
different DesignatedInitExpr is processed by Sema for every instantiation, and
thus the invalid warning is avoided.

Richard Smith 5e9746f520 DR583, DR1512: Implement a rewrite to C++'s 'composite pointer type' rules.
This has two significant effects:

1) Direct relational comparisons between null pointer constants (0 and nullopt)
   and pointers are now ill-formed. This was always the case for C, and it
   appears that C++ only ever permitted by accident. For instance, cases like
     nullptr < &a
   are now rejected.

2) Comparisons and conditional operators between differently-cv-qualified
   pointer types now work, and produce a composite type that both source
   pointer types can convert to (when possible). For instance, comparison
   between 'int **' and 'const int **' is now valid, and uses an intermediate
   type of 'const int *const *'.

Clang previously supported #2 as an extension.

We do not accept the cases in #1 as an extension. I've tested a fair amount of
code to check that this doesn't break it, but if it turns out that someone is
relying on this, we can easily add it back as an extension.

This is a re-commit of r284800.

Richard Smith fdf0888b69 Don't try to use !Previous.empty() as a proxy for "Is this a redeclaration?" --
we don't collapse that down to a single entry if it's not a redeclaration.
Instead, set the Redeclaration bit on the Declarator to indicate whether a
function is a redeclaration (which may not have been linked into the
redeclaration chain if it's a dependent context friend).

Fixes a rejects-valid; see testcase.

Richard Smith 0c1c53e3fa DR583, DR1512: Implement a rewrite to C++'s 'composite pointer type' rules.
This has two significant effects:

1) Direct relational comparisons between null pointer constants (0 and nullopt)
   and pointers are now ill-formed. This was always the case for C, and it
   appears that C++ only ever permitted by accident. For instance, cases like
     nullptr < &a
   are now rejected.

2) Comparisons and conditional operators between differently-cv-qualified
   pointer types now work, and produce a composite type that both source
   pointer types can convert to (when possible). For instance, comparison
   between 'int **' and 'const int **' is now valid, and uses an intermediate
   type of 'const int *const *'.

Clang previously supported #2 as an extension.

We do not accept the cases in #1 as an extension. I've tested a fair amount of
code to check that this doesn't break it, but if it turns out that someone is
relying on this, we can easily add it back as an extension.

Bruno Cardoso Lopes de9cab942b [Driver][Darwin] Pass -no_deduplicate to ld64
Recent versions of ld64 run a deduplicate pass, which is on by default.
Disable the pass by using -no_deduplicate in certain condition and
enhance total compile time.

Bruno Cardoso Lopes ed84df008f [Modules] Add 'no_undeclared_includes' module map attribute
The 'no_undeclared_includes' attribute should be used in a module to
tell that only non-modular headers and headers from used modules are
accepted.

The main motivation behind this is to prevent dep cycles between system
libraries (such as darwin) and libc++.

Reid Kleckner 2e1538f282 Remove 24 instances of 'REQUIRES: shell'
Tests fall into one of the following categories:

- The requirement was unnecessary

- Additional quoting was required for backslashes in paths (see "sed -e
  's/\\/\\\\/g'") in the sanitizer tests.

- OpenMP used 'REQUIRES: shell' as a proxy for the test failing on
  Windows. Those tests fail there reliably, so use XFAIL instead.

I tried not to remove shell requirements that were added to suppress
flaky test failures, but if I screwed up, we can add it back as needed.

Reid Kleckner ae818501b7 Fix off-by-one error in PPCaching.cpp token annotation assertion
This assert is intended to defend against backtracking into the middle
of a sequence of tokens that is being replaced with an annotation, but
it's OK if we backtrack to the exact position of the start of the
annotation sequence. Use a <= comparison instead of <.

Michal Gorny 16f37c30a3 [Driver] Refactor DetectDistro() parameters to take VFS ref only. NFC
Refactor the DetectDistro() function to take a single vfs::FileSystem
reference only, instead of Driver and llvm::Triple::ArchType.
The ArchType parameter was not used anyway, and Driver was only used to
obtain the VFS.

Aside to making the API simpler and more transparent, it makes it
easier to add unit tests for the function in the future -- since
the tests would need only to provide an appropriate VFS.

Replace the string matching for /etc/debian_version with split
integer/string matching algorithm. When the file contains 'major.minor'
version number, parse the major version as integer and use a switch
clause to match it. Otherwise, attempt 'codename/sid' matching using
a StringSwitch.

Ekaterina Romanova 493091fdef Add more doxygen comments to emmintrin.h's intrinsics.
With this patch, 75% of the intrinsics in this file will be documented now. The patches for the rest of the intrisics in this file will be send out later.

The doxygen comments are automatically generated based on Sony's intrinsics document.

I got an OK from Eric Christopher to commit doxygen comments without prior code review upstream. This patch was internally reviewed by Yunzhong Gao.

Renato Golin f46be19104 [clang-cl] Fix test that shouldn't be running on non-x86
The clang-cl test required x86-registered-target but it defaulted to the
host's triple and AArch64 still doesn't support COFF, so the test failed.

The triple was "aarch64-pc-windows-msvc18.0.0" with ObjectFormat equals
llvm::Triple::COFF, failing assertion:

Assertion `(TT.isOSBinFormatELF() || TT.isOSBinFormatMachO()) &&
          "Only expect Darwin and ELF targets"

in AArch64MCTargetDesc.cpp:78.

Making the test only run on Windows hosts obviously fixes the problem.
