Summary:
NaCl is a platform where long double is the same as double.
Its mangling is spelled with "long double" but its ABI lowering is the same
as double.

Following one of the appended options will allow the loop to be vectorized. We do not include a command line option for modifying the pointer checking threshold because there is no clang-level interface for this currently.

A test was recently (r244468) added to cover long double calling convention
codegen, distinguishing between Android and GNU conventions (where long doubles
are fp128 and x86_fp80, respectively). Native Client is a target where long
doubles are the same as doubles. This change augments the test to cover
that case.
Also rename the test to test/codeGen/X86_64-longdouble.c

With this patch clang appends the command line options that would allow vectorization when floating-point commutativity is required. Specifically those are enabling fast-math or specifying a loop hint.

Summary:
The vtable takes its DLL storage class from the class, not the key
function. When they disagree, the vtable won't be exported by the DLL
that defines the key function. The easiest way to ensure that importers
of the class emit their own vtable is to say that the class has no key
function.

cl uses 'CL' and '_CL_' to prepend and append command line options to
the given argument vector. There is an additional quirk whereby '#' is

* Return type of long double (fp128) should be fp128, not x86_fp80.
* Vararg of long double (fp128) could be in register and overflowed to memory.

* Return value of long double (fp128) _Complex should be in memory like a structure of {fp128,fp128}.

This change adds the new unroll metadata "llvm.loop.unroll.enable" which directs
the optimizer to unroll a loop fully if the trip count is known at compile time, and
unroll partially if the trip count is not known at compile time. This differs from
"llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not
known at compile time
With this change "#pragma unroll" generates "llvm.loop.unroll.enable" rather than
"llvm.loop.unroll.full" metadata. This changes the semantics of "#pragma unroll" slightly
to mean "unroll aggressively (fully or partially)" rather than "unroll fully or not at all".
The motivating example for this change was some internal code with a loop marked
with "#pragma unroll" which only sometimes had a compile-time trip count depending
on template magic. When the trip count was a compile-time constant, everything works
as expected and the loop is fully unrolled. However, when the trip count was not a
compile-time constant the "#pragma unroll" explicitly disabled unrolling of the loop(!).
Removing "#pragma unroll" caused the loop to be unrolled partially which was desirable
from a performance perspective.

Summary:
Add brace style `BS_WebKit` as described on https://www.webkit.org/coding/coding-style.html:
* Function definitions: place each brace on its own line.
* Other braces: place the open brace on the line preceding the code block; place the close brace on its own line.
Set brace style used in `getWebKitStyle()` to the newly added `BS_WebKit`.

-mkernel enables -fno-builtin and -fno-common by default, but allows -fbuiltin
and -fcommon to override that. However "-fbuiltin -fno-builtin" is treated the
same as "-fbuiltin" which is wrong, so fix that. Also fixes similar behaviour
when -fno-common is default.

overwrite it with the correct contents after the requested build completes.

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.

- A path sensitive checker that warns about uses of non-localized
NSStrings passed to UI methods expecting localized strings.
- A syntax checker that warns against not including a comment in

The ObjCSuperCallChecker issues alarms for various Objective-C APIs that require
a subclass to call to its superclass's version of a method when overriding it.
So, for example, it raises an alarm when the -viewDidLoad method in a subclass
of UIViewController does not call [super viewDidLoad].
This patch fixes a false alarm where the analyzer erroneously required the
implementation of the superclass itself (e.g., UIViewController) to call
super.

Function types without prototypes can arise when mangling a function type
within an overloadable function in C. We mangle these as the absence of
any parameter types (not even an empty parameter list).

... and add aarch32 to specifically refer to the 32-bit ones.
Previously, 'arm' meant only 32-bit architectures and there was no way
for a module to build with both 32 and 64 bit ARM architectures.
Now a module that is intended to work on both architectures can specify
requires arm
whereas a module only for 32-bit platforms can say
requires aarch32
and just like before, 64-bit only can say
requires aarch64
