    Add flag to request Clang is ABI-compatible with older versions of itself

    This patch adds a flag -fclang-abi-compat that can be used to request that
    Clang attempts to be ABI-compatible with some older version of itself.

    This is provided on a best-effort basis; right now, this can be used to undo
    the ABI change in r310401, reverting Clang to its prior C++ ABI for pass/return
    by value of class types affected by that change, and to undo the ABI change in
    r262688, reverting Clang to using integer registers rather than SSE registers
    for passing <1 x long long> vectors. The intent is that we will maintain this
    backwards compatibility path as we make ABI-breaking fixes in future.

    The reversion to the old behavior for r310401 is also applied to the PS4 target
    since that change is not part of its platform ABI (which is essentially to do
    whatever Clang 3.2 did).

    [Format] Invert nestingAndIndentLevel pair in WhitespaceManager used for
    alignments

    Indent should be compared before nesting level to determine if a token
    is on the same scope as the one we align with. Because it was inverted,
    clang-format sometimes tried to align tokens with tokens from outer
    scopes, causing the assert(Shift >= 0) to fire.

    This fixes bug #33507. Patch by Beren Minor, thank you!

    [ubsan] PR34266: When sanitizing the 'this' value for a member function that happens to be a lambda call operator, use the lambda's 'this' pointer, not the captured enclosing 'this' pointer (if any).

    Do not sanitize the 'this' pointer of a member call operator for a lambda with
    no capture-default, since that call operator can legitimately be called with a
    null this pointer from the static invoker function. Any actual call with a null
    this pointer should still be caught in the caller (if it is being sanitized).

    This reinstates r311589 (reverted in r311680) with the above fix.

    Revert r309328 and r309290 (which merged r309327 and r309226).

    The header change caused problems; see PR34182, and PR33858 from #9 onwards, as
    well as the discussion on the r309226 cfe-commits thread.

    These changes don't seem to be addressing any regression from 4.0.0, so rather
    than scrambling to fix this on the branch, let's revert to safety.

    Should go into clang-5.0 IMHO.

    [Driver] Recognize DevDiv internal builds of MSVC, with a different directory structure.

    This is a reasonably non-intrusive change, which I've verified
    works for both x86 and x64 DevDiv-internal builds.

    The idea is to change `bool IsVS2017OrNewer` into a 3-state
    `ToolsetLayout VSLayout`. Either a build is DevDiv-internal,
    released VS 2017 or newer, or released VS 2015 or older. When looking at
    the directory structure, if instead of `"VC"` we see `"x86ret"`, `"x86chk"`,
    `"amd64ret"`, or `"amd64chk"`, we recognize this as a DevDiv-internal build.

    After we get past the directory structure validation, we use this knowledge
    to regenerate paths appropriately. `llvmArchToDevDivInternalArch()` knows how
    we use `"i386"` subdirectories, and `MSVCToolChain::getSubDirectoryPath()`
    uses that. It also knows that DevDiv-internal builds have an `"inc"`
    subdirectory instead of `"include"`.

    This may still not be the "right" fix in any sense, but I believe that it's
    non-intrusive in the sense that if the special directory names aren't found,
    no codepaths are affected. (`ToolsetLayout::OlderVS` and
    `ToolsetLayout::VS2017OrNewer` correspond to `IsVS2017OrNewer` being `false`
    or `true`, respectively.) I searched for all references to `IsVS2017OrNewer`,
    which are places where Clang cares about VS's directory structure, and the
    only one that isn't being patched is some logic to deal with
    cross-compilation. I'm fine with that not working for DevDiv-internal builds
    for the moment (we typically test the native compilers), so I added a comment.

    Fixes D36860.

    [ObjC] Check written attributes only when synthesizing ambiguous property

    This commit fixes a bug introduced in r307903. The attribute ambiguity checker
    that was introduced in r307903 checked all property attributes, which caused
    errors for source-compatible properties, like:

    @property (nonatomic, readonly) NSObject *prop;
    @property (nonatomic, readwrite) NSObject *prop;

    because the readwrite property would get implicit 'strong' attribute. The
    ambiguity checker should be concerned about explicitly specified attributes
    only.

    PR19668, PR23034: Fix handling of move constructors and deleted copy
    constructors when deciding whether classes should be passed indirectly.

    This fixes ABI differences between Clang and GCC:

     * Previously, Clang ignored the move constructor when making this
       determination. It now takes the move constructor into account, per
       https://github.com/itanium-cxx-abi/cxx-abi/pull/17 (this change may
       seem recent, but the ABI change was agreed on the Itanium C++ ABI
       list a long time ago).

     * Previously, Clang's behavior when the copy constructor was deleted
       was unstable -- depending on whether the lazy declaration of the
       copy constructor had been triggered, you might get different behavior.
       We now eagerly declare the copy constructor whenever its deletedness
       is unclear, and ignore deleted copy/move constructors when looking for
       a trivial such constructor.

    This also fixes an ABI difference between Clang and MSVC:

     * If the copy constructor would be implicitly deleted (but has not been
       lazily declared yet), for instance because the class has an rvalue
       reference member, we would pass it directly. We now pass such a class
       indirectly, matching MSVC.

    Based on a patch by Vassil Vassilev, which was based on a patch by Bernd
    Schmidt, which was based on a patch by Reid Kleckner!

    This is a re-commit of r310401, which was reverted in r310464 due to ARM
    failures (which should now be fixed).

    [analyzer] Fix modeling of constructors

    This diff fixes analyzer's crash (triggered assert) on the newly added test case.
    The assert being discussed is assert(!B.lookup(R, BindingKey::Direct))
    in lib/StaticAnalyzer/Core/RegionStore.cpp, however the root cause is different.
    For classes with empty bases the offsets might be tricky.
    For example, let's assume we have
     struct S: NonEmptyBase, EmptyBase {
         ...
     };
    In this case Clang applies empty base class optimization and
    the offset of EmptyBase will be 0, it can be verified via
    clang -cc1 -x c++ -v -fdump-record-layouts main.cpp -emit-llvm -o /dev/null.
    When the analyzer tries to perform zero initialization of EmptyBase
    it will hit the assert because that region
    has already been "written" by the constructor of NonEmptyBase.

    Test plan:
    make check-all

    PR34163: Don't cache an incorrect key function for a class if queried between
    the class becoming complete and its inline methods being parsed.

    This replaces the hack of using the "late parsed template" flag to track member
    functions with bodies we've not parsed yet; instead we now use the "will have
    body" flag, which carries the desired implication that the function declaration
    *is* a definition, and that we've just not parsed its body yet.

    The local variable `a` of the function `f` can't be accessed from a method of
    the function-local class A, thus no shadowing occurs and no diagnostic is
    needed.

    When using nested classes, if the inner class is not templated, but the outer

    traits as if it were.  This is particularly evident if the inner class

    [X86] Enable isel to use the PAUSE instruction even when SSE2 is disabled. Clang part

    Summary:
    On older processors this instruction encoding is treated as a NOP.

    MSVC doesn't disable intrinsics based on features the way clang/gcc does. Because the PAUSE instruction encoding doesn't crash older processors, some software out there uses these intrinsics without checking for SSE2.

    This change also seems to also be consistent with gcc behavior.

    Headers: improve ARM EHABI coverage of unwind.h

    Ensure that we define the `_Unwind_Control_Block` structure used on ARM
    EHABI targets.  This is needed for building libc++abi with the unwind.h
    from the resource dir.  A minor fallout of this is that we needed to
    create a typedef for _Unwind_Exception to work across ARM EHABI and
    non-EHABI targets.  The structure definitions here are based originally
    on the documentation from ARM under the "Exception Handling ABI for the
    ARM® Architecture" Section 7.2.  They are then adjusted to more closely
    reflect the definition in libunwind from LLVM.  Those changes are
    compatible in layout but permit easier use in libc++abi and help
    maintain compatibility between libunwind and the compiler provided
    definition.

    [CodeGen] Correctly model std::byte's aliasing properties

    std::byte, when defined as an enum, needs to be given special treatment
    with regards to its aliasing properties. An array of std::byte is
    allowed to be used as storage for other types.

    This fixes PR33916.

    Work around an MSVC2017 update 3 codegen bug.

    C2017 update 3 produces a clang that crashes when compiling clang. Disabling
    optimizations for StmtProfiler::VisitCXXOperatorCallExpr() makes the crash go
    away.

    Revert r308441 "Recommit r308327: Add a warning for missing '#pragma pack (pop)' and suspicious uses of '#pragma pack' in included files"

    This seems to have broken the sanitizer-x86_64-linux buildbot. Reverting until
    it's fixed, especially since this landed just before the 5.0 branch.

    > This commit adds a new -Wpragma-pack warning. It warns in the following cases:
    >
    > - When a translation unit is missing terminating #pragma pack (pop) directives.
    > - When entering an included file if the current alignment value as determined
    >   by '#pragma pack' directives is different from the default alignment value.

    [Cilk] Added preliminary support for _Cilk_spawn assignments and declarations.

    This commit adds support for the following statements and expressions:

    var = _Cilk_spawn function-call
    vardecl = _Cilk_spawn function-call

    This support should be easily extensible to support spawned compound
    assignments by means of Cilk inlets.

    To support these statements and expressions, this commit adds a CilkSpawnExpr
    expression type, which has a single child subexpression.  Although
    _Cilk_spawn cannot be applied to any expression, this approach of adding a
    general CilkSpawnExpr seems to be the simplest for adapting the parser to
    handle the cases we care about.  Additional semantic checks should be added
    later to ensure that a CilkSpawnExpr appears only where it makes semantic
    sense.

    _Cilk_spawn assignments and declarations differ from ordinary assignments and
    declarations in their order of evaluation.  For a typical assignment or
    declaration,

    E1 @= E2

    C++17 rules dictate that E2 is evaluated before E1.  When E2 is preceded by
    a _Cilk_spawn, however, we no longer guarantee that E2 is evaluated before
    E1.  (This commit, in fact, ensures that E1 is evaluated before E2 if E2 is
    spawned.)  In effect, the _Cilk_spawn weakens the evaluation-order
    guarantees of the spawned expression and code evaluated afterwards.

    This commit also improves the handling of evaluated expressions around Cilk
    constructs.  These improvements include fixes to the evaluation order of
    arguments to a spawned function, creation of temporary storage for spawned
    function calls, and processing of exception-handling code created for
    spawned expressions.  This commit also reorganizes some Cilk-specific code
    into separate files.

Cilk-Clang
================================

This version of Clang supports the `_Cilk_spawn`, `_Cilk_sync`, and
`_Cilk_for` keywords from Cilk. In particular, this version of Clang
supports the use of _Cilk_spawn before a function call in a statement,
an assignment, or a declaration, as in the following examples:

```
_Cilk_spawn foo(n);
```

```
x = _Cilk_spawn foo(n);
```

```
int x = _Cilk_spawn foo(n);
```

When spawning a function call, the call arguments and function
arguments are evaluated before the spawn occurs. When spawning an
assignment or declaration, the LHS is also evaluated before the spawn
occurs.

For convenience, this version of Clang allows `_Cilk_spawn` to spawn an
arbitrary statement, as follows:

```
_Cilk_spawn { x = foo(n); }
```

Please use this syntax with caution! When spawning an arbitrary
statement, the spawn occurs before the evaluation of any part of the
spawned statement. Furthermore, some statements, such as `goto`, are
not legal to spawn. In the future, we will add checks to catch
illegal uses of `_Cilk_spawn`.
