Richard Smith 1e8e91b379 PR25501: Delay loading visible updates for a declaration until after we've
processed update records. If an update record adds a definition, we need to
merge that with any pre-existing definition to determine which the canonical
definition is before we apply the visible update, otherwise we wouldn't know
where to apply it.

Thanks to Vassil Vassilev for help reducing this and tracking down the problem.

The doxygen comments are automatically generated based on Sony's intrinsics document.

I got an OK from Eric Christopher to commit doxygen comments without prior code review upstream. This patch was internally reviewed by Paul Robinson.

Devin Coughlin ebaa56bb26 [analyzer] Teach trackNullOrUndefValue about calls to property accessors.
Teach trackNullOrUndefValue() how to look through PseudoObjectExprs to find
the underlying method call for property getters. This makes over-suppression
of 'return nil' in getters consistent with the similar over-suppression for
method and function calls.

Saleem Abdulrasool f7b3d6c55b Move EABIVersion from CodeGenOptions to TargetOptions
It is possible to argue that the EABIVersion field is similar in spirit to the
ABI field in TargetOptions.  It represents the embedded ABI that the target
follows.  This will allow us to thread this information into the target
information construction.

Saleem Abdulrasool 10a4972a8d revert SVN r265702, r265640
Revert the two changes to thread CodeGenOptions into the TargetInfo allocation
and to fix the layering violation by moving CodeGenOptions into Basic.
Code Generation is arguably not particularly "basic".  This addresses Richard's
post-commit review comments.  This change purely does the mechanical revert and
will be followed up with an alternate approach to thread the desired information
into TargetInfo.

Alexey Bader 954ba21f85 [OpenCL] Complete image types support.
I. Current implementation of images is not conformant to spec in the following points:
  1. It makes no distinction with respect to access qualifiers and therefore allows to use images with different access type interchangeably. The following code would compile just fine:

        void write_image(write_only image2d_t img);
        kernel void foo(read_only image2d_t img) { write_image(img); } // Accepted code

     which is disallowed according to s6.13.14.

  2. It discards access qualifier on generated code, which leads to generated code for the above example:

        call void @write_image(%opencl.image2d_t* %img);

     In OpenCL2.0 however we can have different calls into write_image with read_only and wite_only images.
     Also generally following compiler steps have no easy way to take different path depending on the image access: linking to the right implementation of image types, performing IR opts and backend codegen differently.

  3. Image types are language keywords and can't be redeclared s6.1.9, which can happen currently as they are just typedef names.
  4. Default access qualifier read_only is to be added if not provided explicitly.

II. This patch corrects the above points as follows:
  1. All images are encapsulated into a separate .def file that is inserted in different points where image handling is required. This avoid a lot of code repetition as all images are handled the same way in the code with no distinction of their exact type.
  2. The Cartesian product of image types and image access qualifiers is added to the builtin types. This simplifies a lot handling of access type mismatch as no operations are allowed by default on distinct Builtin types. Also spec intended access qualifier as special type qualifier that are combined with an image type to form a distinct type (see statement above - images can't be created w/o access qualifiers).
  3. Improves testing of images in Clang.

Justin Lebar 25c36fd61b [CUDA] Tweak math forward declares so we're compatible with libstdc++4.9.
Summary:
See comments in patch; we were assuming that some stdlib math functions
would be defined in namespace std, when in fact the spec says they
should be defined in the global namespace.  libstdc++4.9 became more
conforming and broke us.

This new implementation seems to cover the known knowns.

Richard Smith 351241c83e Replace Sema-level implementation of -fassume-sane-operator-new with a
CodeGen-level implementation. Instead of adding an attribute to clang's
FunctionDecl, add the IR attribute directly. This means a module built with
this flag is now compatible with code built without it and vice versa.

This change also results in the 'noalias' attribute no longer being added to
calls to operator new in the IR; it's now only added to the declaration. It
also fixes a bug where we failed to add the attribute to the 'nothrow' versions
(because we didn't implicitly declare them, there was no good time to inject a
fake attribute).

Manman Ren d2a3cd7261 NFC: simplify code in BuildInstanceMessage.
Instead of searching the global pool multiple times: in
LookupFactoryMethodInGlobalPool, LookupInstanceMethodInGlobalPool,
CollectMultipleMethodsInGlobalPool, and AreMultipleMethodsInGlobalPool,
we now collect the method candidates in CollectMultipleMethodsInGlobalPool
only, and other functions will use the collected method set.

This commit adds parameter "Methods" to AreMultipleMethodsInGlobalPool,
and SelectBestMethod. It also changes the implementation of
CollectMultipleMethodsInGlobalPool to collect the desired kind first, if none is
found, to collect the other kind. This avoids the need to call both
LookupFactoryMethodInGlobalPool and LookupInstanceMethodInGlobalPool.

Ed Schouten 506f295a10 Enable PIE for CloudABI.
As we're currently working on making CloudABI executables easier to
emulate in userspace (e.g., on OS X and Windows), it makes a whole lot
of sense to build these using PIE. By using PIE, they can simply be
loaded into the existing process address space without clashes.

PIE support got added to CloudABI's C library and seems to work pretty
well. CloudABI does not make use of an ld.so, so the binary's _start()
has all the logic in it to do the relocations.

Now that all but one bug in LLD relating to PIE support have been
squashed (and a patch for that is already in code review), I'd like to
go ahead and force the use of PIE for Clang 3.9. When released, we'll
also switch over to using LLD exclusively.

Add parsing, sema analysis for 'declare target' construct for OpenMP 4.0

The declare target directive specifies that variables, functions (C, C++

target directive is a declarative directive. In Clang declare target is
implemented as implicit attribute for the declaration.

The syntax of the declare target directive is as follows:

 #pragma omp declare target
