This function permits the mangling of a C++ 'structor. Depending on the ABI and
the declaration, the declaration may contain more than one associated symbol for
a given declaration. This allows the consumer to retrieve all of the associated

Cwd::abs_path has a somewhat tricky semantics: if it's operand directory does not exist,
it'll return undefined (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=257568).
This may cause scan-build to silently ignore output directory (specified with -o) and
use /tmp instead of trying to create directory. This tiny patch fixes the problem.

If no arguments are specified, it formats the code from standard input
and writes the result to the standard output.
If <file>s are given, it reformats the files. If -i is specified
together with <file>s, the files are edited in-place. Otherwise, the
result is written to the standard output.
USAGE: clang-format [options] [<file> ...]
OPTIONS:
-assume-filename=<string> - When reading from stdin, clang-format assumes this
filename to look for a style config file (with
-style=file) and to determine the language.
-cursor=<uint> - The position of the cursor when invoking
clang-format from an editor integration
-dump-config - Dump configuration options to stdout and exit.
Can be used with -style option.
-fallback-style=<string> - The name of the predefined style used as a
fallback in case clang-format is invoked with
-style=file, but can not find the .clang-format
file to use.
Use -fallback-style=none to skip formatting.
-help - Display available options (-help-hidden for more)
-i - Inplace edit <file>s, if specified.
-length=<uint> - Format a range of this length (in bytes).
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
When only a single -offset is specified without
-length, clang-format will format up to the end
of the file.
Can only be used with one input file.
-lines=<string> - <start line>:<end line> - format a range of
lines (both 1-based).
Multiple ranges can be formatted by specifying
several -lines arguments.
Can't be used with -offset and -length.
Can only be used with one input file.
-offset=<uint> - Format a range starting at this byte offset.
Multiple ranges can be formatted by specifying
several -offset and -length pairs.
Can only be used with one input file.
-output-replacements-xml - Output replacements as XML.
-sort-includes - Sort touched include lines
-style=<string> - Coding style, currently supports:
LLVM, Google, Chromium, Mozilla, WebKit.
Use -style=file to load style configuration from
.clang-format file located in one of the parent
directories of the source file (or current
directory for stdin).
Use -style="{key: value, ...}" to set specific
parameters, e.g.:
-style="{BasedOnStyle: llvm, IndentWidth: 8}"
-version - Display the version of this program output.

logic to select an alternate target based on the executable it was
called as. For instance, if you symlink i686-linux-android-gcc to clang
and invoke it, the driver will act as though it were called with another
argument ("-target i686-linux-android"). This leads to visible effects
even in syntax-only compilations (like the ANDROID preprocessor symbol
being defined).
This behavior is not replicated for tool invocations--for instance,
clang::createInvocationFromCommandLine will not choose an alternate
target based on ArgList[0]. This means that configurations stored in
compilation databases aren't accurately replayed.
This patch separates the logic for selecting a mode flag and target from
the executable name into a new member function on ToolChain. It should
have no functional effects (but will allow other code to reuse the
target/mode selection logic).

The loop region to which an ordered region without any clause or with a threads clause binds must have an ordered clause without the parameter specified on the corresponding loop directive.

Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).
For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.
This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

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

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

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.

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

// this example is adapted from the example for "struct fred x[]" in DR-253;
// currently clang produces in l: { "\0\0x" },
// whereas gcc 4.8 produces { "fox" };
// with this fix, clang will also produce: { "fox" };

When clang-format encounters a syntax error, it will not format that
line; we're now using the same mechanism we're already using in emacs to
show a helpful error message to the user.

Complains:
/home/buildbots/sanitizerslave1/sanitizer-ppc64-1/build/llvm/tools/clang/tools/c-index-test/c-index-test.c:829:30: error: format specifies type 'long' but the argument has type 'long long' [-Werror,-Wformat]
I, TAK, clang_Cursor_getTemplateArgumentValue(Cursor, I));

I'm not sure now how this should be fixed. %lld is non-standard
and not accepted by mingw on Windows while PRId64 is bad for this bot.
Is long long longer than 64 bits here? if not, why is PRId64
incompatible with it? something seems wrong.
Probably all the datatypes should be replaced to unsigned or uint64_t
depending upin requirements instead of the non standard long long.
