Alex Lorenz 977ffd7b8f [libclang] CoroutineBody/Coreturn statements are UnexposedStmts and not Exprs
This change ensures that the libclang CXCursor represents the CoroutineBody
and the Coreturn statement using the appropriate CXCursor_UnexposedStmt kind
instead of CXCursor_UnexposedExpr. The problem with CXCursor_UnexposedExpr is
that the consumer functions assumed that CoroutineBody/Coreturn statements
were valid expressions and performed an invalid downcast to Expr causing
assertion failures or other crashes.

Nico Weber 06519794da Make test/Driver/darwin-sdk-version.c pass if the host triple is 32-bit
For some reason, the cmake build on my macbook has
LLVM_HOST_TRIPLE:STRING=i386-apple-darwin16.7.0 .
test/Driver/darwin-sdk-version.c assumed that the host triple is 64-bit, so
make it resilient against 32-bit host triples.

Pete Cooper de0a8d37a0 Only convert objc messages to alloc to objc_alloc if the receiver is a class.
r348687 converted [Foo alloc] to objc_alloc(Foo).  However the objc runtime method only takes a Class, not an arbitrary pointer.

This makes sure we are messaging a class before we convert these messages.

Reid Kleckner a643e6449b [clang-cl] Treat inputs as C++ with /E, like MSVC
midl invokes the compiler on .idl files with /E. Before this change, we
would treat unrecognized inputs as object files. Now we pre-process to
stdout as expected. I checked that MSVC defines __cplusplus when invoked
this way, so treating the input as C++ seems like the right thing to do.

After this change, I was able to run midl like this with clang-cl:
$ midl -cpp_cmd clang-cl.exe foo.idl

Things worked for the example IDL file in the Microsoft documentation,
but beyond that, I don't know if this will work well.

Michal Gorny dae01c352b [Driver] Disable -faddrsig on Gentoo by default
Gentoo supports combining clang toolchain with GNU binutils, and many
users actually do that.  As -faddrsig is not supported by GNU strip,
this results in a lot of warnings.  Disable it by default and let users
enable it explicitly if they want it; with the intent of reevaluating
when the underlying feature becomes standarized.

Bruno Ricci ddb8f6b83a [AST] Store the arguments of CXXConstructExpr in a trailing array
Store the arguments of CXXConstructExpr in a trailing array. This is very
similar to the CallExpr case in D55771, with the exception that there is
only one derived class (CXXTemporaryObjectExpr) and that we compute the
offset to the trailing array instead of storing it.

This saves one pointer per CXXConstructExpr and CXXTemporaryObjectExpr.

Artem Dergachev 02955afbb4 [analyzer] pr38668: Do not attempt to cast loaded integers to floats.
This patch is a different approach to landing the reverted r349701.

It is expected to have the same object (memory region) treated as if it has
different types in different program points. The correct behavior for
RegionStore when an object is stored as an object of type T1 but loaded as
an object of type T2 is to store the object as if it has type T1 but cast it
to T2 during load.

Note that the cast here is some sort of a "reinterpret_cast" (even in C). For
instance, if you store an integer and load a float, you won't get your integer
represented as a float; instead, you will get garbage.

Admit that we cannot perform the cast and return an unknown value.

Bruno Ricci c5885cffc5 [AST] Store the callee and argument expressions of CallExpr in a trailing array.
Since CallExpr::setNumArgs has been removed, it is now possible to store the
callee expression and the argument expressions of CallExpr in a trailing array.
This saves one pointer per CallExpr, CXXOperatorCallExpr, CXXMemberCallExpr,
CUDAKernelCallExpr and UserDefinedLiteral.

Given that CallExpr is used as a base of the above classes we cannot use
llvm::TrailingObjects. Instead we store the offset in bytes from the this pointer
to the start of the trailing objects and manually do the casts + arithmetic.

Some notes:

1.) I did not try to fit the number of arguments in the bit-fields of Stmt.
    This leaves some space for future additions and avoid the discussion about
    whether x bits are sufficient to hold the number of arguments.

2.) It would be perfectly possible to recompute the offset to the trailing
    objects before accessing the trailing objects. However the trailing objects
    are frequently accessed and benchmarks show that it is slightly faster to
    just load the offset from the bit-fields. Additionally, because of 1),
    we have plenty of space in the bit-fields of Stmt.
