to enable the use of external type references in the debug info
(a.k.a. module debugging).
The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

Adds parsing/sema analysis/serialization/deserialization for array sections in OpenMP constructs (introduced in OpenMP 4.0).

After r244870 flush() will only compare two null pointers and return,
doing nothing but wasting run time. The call is not required any more

cl uses 'CL' and '_CL_' to prepend and append command line options to

When interposing on a compiler doing cross-compilation, scan-build
does not infer the target triple needed to pass to clang for
doing static analysis. The --analyzer-target option allows one
to manually specify the target triple used during static analysis
(and only static analysis) for such cases.

noticed until now.
The code for setting up the driver's InstalledDir didn't respect
-no-canonical-prefixes. Because of this, there are a few places in the
driver where we would unexpectedly form absolute paths, notably when
searching for and finding GCC installations to use, etc. The fix is
straightforward, and I've added this path to '-v' both so we can test it
sanely and so that it will be substantially more obvious the next time
someone has to debug something here.
Note that there is another bug that we don't actually *canonicalize* the
installed directory! I don't really want to fix that because I don't
have a realistic way to test the usage of this mode. I suspect that
folks using the shared module cache would care about getting this right
though, and so they might want to address it. I've left the appropriate
FIXMEs so that it is clear what to change, and I've updated the test
code to make it clear what is happening here.

a bad call to memcpy.
When we only have a buffer from one of the two reparse calls, we can
just return that buffer rather than going through the realloc/memcpy
dance.

In llvm commit r243581, a reverse range adapter was added which allows
us to change code such as
for (auto I = Fields.rbegin(), E = Fields.rend(); I != E; ++I) {
in to
for (const FieldDecl *I : llvm::reverse(Fields))
This commit changes a few of the places in clang which are eligible to use
this new adapter.

OpenMP 4.1 introduces optional argument '(n)' for 'ordered' clause, where 'n' is a number of loops that immediately follow the directive.
'n' must be constant positive integer expressions and it must be less or equal than the number of the loops in the resulting loop nest.
Patch adds parsing and semantic analysis for this optional argument.

In clang cc1as_main, when the output file type is “asm”, AsmStreamer
owns a formatted_raw_ostream which has a reference to FDOS
(raw_ostream), so AsmStreamer must be closed before FDOS is closed.

- introduces a new cc1 option -fmodule-format=[raw,obj]
with 'raw' being the default
- supports arbitrary module container formats that libclang is agnostic to
- adds the format to the module hash to avoid collisions
- splits the old PCHContainerOperations into PCHContainerWriter and
a PCHContainerReader.

We were still using the Unix response file tokenizer for all driver
modes. This was difficult to get right in the beginning because there is
a circular dependency. The Driver class also can't officially determine
its mode until it can see all possible --driver-mode= flags, and those
flags could come from the response file.
Now we use the Windows parsing algorithm if the program name looks like
clang-cl, or if the --driver-mode=cl flag is present on the main command
line.
Fixes PR23709.

and includes fix for OS X test failures.
- Changed driver pipeline to compile host and device side of CUDA
files and incorporate results of device-side compilation into host
object file.
- Added a test for cuda pipeline creation in clang driver.
New clang options:
--cuda-host-only - Do host-side compilation only.
--cuda-device-only - Do device-side compilation only.
--cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
than once in which case one device-compilation will be done per
unique specified GPU architecture.

One of the problems libclang tests has running under Windows is memory
allocated in libclang.dll but being freed in the test executable, possibly
by a different memory manager. This patch exposes a new export function,
clang_free(), used to free any allocated memory with the same libclang.dll
memory manager that allocated the memory.

This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.
This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

Teach C++'s tentative parsing to handle specializations of Objective-C
class types (e.g., NSArray<NSString *>) as well as Objective-C
protocol qualifiers (id<NSCopying>) by extending type-annotation
tokens to handle this case. As part of this, remove Objective-C
protocol qualifiers from the declaration specifiers, which never
really made sense: instead, provide Sema entry points to make them
part of the type annotation token. Among other things, this properly
diagnoses bogus types such as "<NSCopying> id" which should have been
written as "id <NSCopying>".
Implements template instantiation support for, e.g., NSArray<T>*
in C++. Note that parameterized classes are not templates in the C++
sense, so that cannot (for example) be used as a template argument for
a template template parameter. Part of rdar://problem/6294649.
llvm-svn: 241545
Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).
Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.
Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.
llvm-svn: 241542
Produce type parameter declarations for Objective-C type parameters,
and attach lists of type parameters to Objective-C classes,
categories, forward declarations, and extensions as
appropriate. Perform semantic analysis of type bounds for type
parameters, both in isolation and across classes/categories/extensions
to ensure consistency.
Also handle (de-)serialization of Objective-C type parameter lists,
along with sundry other things one must do to add a new declaration to
Clang.
Note that Objective-C type parameters are typedef name declarations,
like typedefs and C++11 type aliases, in support of type erasure.
