Sven van Haastregt 14947cd047 [clang] Fix signedness in vector bitcast evaluation
The included test case triggered a sign assertion on the result in
`Success()`.  This was caused by the APSInt created for a bitcast
having its signedness bit inverted.  The second APSInt constructor
argument is `isUnsigned`, so invert the result of
`isSignedIntegerType`.

Suppress non-conforming GNU paste extension in all standard-conforming modes
The GNU token paste extension that removes the comma in , ## __VA_ARGS__
conflicts with C99/C++11's requirements when a variadic macro has no
named parameters: according to the standard, an invocation as FOO()
gives it a single empty argument, and concatenation of anything with an
empty argument is well-defined. For this reason, the GNU extension was
already disabled in C99 standard-conforming mode. It was not yet
disabled in C++11 standard-conforming mode.

The associated comment suggested that GCC keeps this extension enabled
in C90/C++03 standard-conforming mode, but it actually does not, so
rather than adding a check for C++ language version, this change simply
removes the check for C language version.

Rather than reimplement, use a `using` declaration to bring in
`SmallVectorImpl<char>`'s assign and append implementations in
`SmallString`.

The `SmallString` versions were missing reference invalidation
assertions from `SmallVector`. This patch also fixes a bug in
`llvm::FileCollector::addFileImpl`, which was a copy/paste from
`clang::ModuleDependencyCollector::copyToRoot`, both caught by the
no-longer-skipped assertions.

As a drive-by, this also sinks the `const SmallVectorImpl&` versions of
these methods down into `SmallVectorImpl`, since I imagine they'd be

When a function is declared with a qualified name, its eventual semantic
DeclContext may differ from the scope specified by the qualifier if it
redeclares a function in an inline namespace. In this case, we need to
update the DeclContext to be that of the previous declaration, and we
need to do so before we decide whether to inherit default arguments from
that previous declaration, because we only inherit default arguments
from declarations in the same scope.

Mikhail Maltsev a0e30914f8 [clang][Tooling] Get rid of a hack in SymbolOccurrences, NFCI
The class `SymbolOccurrences` can store either a single `SourceRange`
in-place or multiple `SourceRanges` on the heap. In the latter case
the number of source ranges is stored in the internal representation
of the beginning `SourceLocation` of the in-place `SourceRange`
object.

This change gets rid of such hack by placing `SourceRange` in a union
which holds either a valid `SourceRange` or an `unsigned int` (a number
of ranges).

The change also adds `static_assert`s that check that `SourceRange` and
`SourceLocation` are trivially destructible (this is required for the
current patch and for D94237 which has already been committed).

Argyrios Kyrtzidis b0e89906f5 [ASTReader] Allow controlling separately whether validation should be disabled for a PCH vs a module file
This addresses an issue with how the PCH preable works, specifically:

1. When using a PCH/preamble the module hash changes and a different cache directory is used
2. When the preamble is used, PCH & PCM validation is disabled.

Due to combination of #1 and #2, reparsing with preamble enabled can end up loading a stale module file before a header change and using it without updating it because validation is disabled and it doesn’t check that the header has changed and the module file is out-of-date.

Akira Hatanaka 3d349ed7e1 [CodeGen][ObjC] Fix broken IR generated when there is a nil receiver
check

This patch fixes a bug in emitARCOperationAfterCall where it inserts the
fall-back call after a bitcast instruction and then replaces the
bitcast's operand with the result of the fall-back call. The generated
IR without this patch looks like this:

msgSend.call:                                     ; preds = %entry
  %call = call i8* bitcast (i8* (i8*, i8*, ...)* @objc_msgSend
  br label %msgSend.cont

msgSend.null-receiver:                            ; preds = %entry
  call void @llvm.objc.release(i8* %4)
  br label %msgSend.cont

msgSend.cont:
  %8 = phi i8* [ %call, %msgSend.call ], [ null, %msgSend.null-receiver ]
  %9 = bitcast i8* %10 to %0*
  %10 = call i8* @llvm.objc.retain(i8* %8)

Notice that `%9 = bitcast i8* %10` to %0* is taking operand %10 which is
defined after it.

To fix the bug, this patch modifies the insert point to point to the
bitcast instruction so that the fall-back call is inserted before the
bitcast. In addition, it teaches the function to look at phi
instructions that are generated when there is a check for a null
receiver and insert the retainRV/claimRV instruction right after the
call instead of inserting a fall-back call right after the phi
instruction.

Artem Belevich 127091bfd5 [CUDA] Normalize handling of defauled dtor.
Defaulted destructor was treated inconsistently, compared to other
compiler-generated functions.

When Sema::IdentifyCUDATarget() got called on just-created dtor which didn't
have implicit __host__ __device__ attributes applied yet, it would treat it as a
host function.  That happened to (sometimes) hide the error when dtor referred
to a host-only functions.

Even when we had identified defaulted dtor as a HD function, we still treated it
inconsistently during selection of usual deallocators, where we did not allow
referring to wrong-side functions, while it is allowed for other HD functions.

This change brings handling of defaulted dtors in line with other HD functions.

D94745 rewrites the `deviceRTLs` using OpenMP and compiles it by directly
calling the device compilation. `clang` crashes because entry in
`OffloadEntriesDeviceGlobalVar` is unintialized. Current design supposes the
device compilation can only be invoked after host compilation with the host IR
such that `clang` can initialize `OffloadEntriesDeviceGlobalVar` from host IR.
This avoids us using device compilation directly, especially when we only have
code wrapped into `declare target` which are all device code. The same issue
also exists for `OffloadEntriesInfoManager`.

In this patch, we simply initialized an entry if it is not in the maps. Not sure
we need an option to tell the device compiler that it is invoked standalone.
