Removing some attribute magic related to the OpenCL keyword attributes. Instead of mapping them to their semantics as a custom part of the parser, they instead map declaratively through the rest of the attribute system.

This will allow it to be called from target independent parts of the main
streamer that don't know if there is a registered target streamer or not. This
in turn will allow targets to perform extra actions at specified points in the
interface: add extra flags for some labels, extra work during finalization, etc.

don't know their bit alignment.

llvm-svn: 199173

This patch makes a small behavioral change to the interaction between 
pack and alignment.  Specifically it makes __declspec(align()) on a 
field change that field's alignment without respect to pack but the 
alignment change to the record alignment as a whole still obeys pack.

Record layout will tell us the offset of a shared vbptr inside a
non-virtual base.

No functionality change.

consumable objects.  These are useful for implementing error codes that
must be checked.  Patch also includes some significant refactoring, which was
necesary to implement the new behavior.

llvm-svn: 199169

Although VBPtrs were being placed correctly by the ms-abi layout engine, 
their offsets were being improperly reported to the ASTRecordLayout 
builder due to a bug.  This patch fixes that and fixes the test cases to 
use the correct values.

Fixes PR18435, where we generated a base ctor instead of a complete
ctor, and so failed to construct virtual bases when constructing the
complete object.

This patch moves the check for pragma pack until after the application 
of __declspec align to before pragma pack.  This causes observable 
changes in the use of tail padding for bases.  A test case is included.

For example, don't fall back in /P (preprocess) mode.

so bump the minimum version in the standalone Clang CMake project as
well.

As I mentioned on the LLVM commit version of this, if this causes any
trouble for folks, just let me know. I'm trying to avoid re-implementing
functionality in CMake, but I will if there are problems using the newer
versions.

HandleLLVMOptions. This will also let it be used from the standalone
Clang builds.

compiler version checking doesn't work on 2.8.7. This feature was
documented in 2.8.10, but existed for an unknown amount of time before
that.

I'm actually happy to revert this and remove the use of the feature if
there is anyone with a specific problem updating CMake. Please just let
me know. I don't want to re-implement this CMake functionality unless
there is a reason, and this is the only real way to find that out.

likely to be reverted and re-applied a few times. The minimum versions
we're aiming at:

  Clang 3.1
  MSVC 17.0 (Visual Studio 2012)

Let me know if something breaks!

When determining the attribute's parsed kind, pay attention to the syntax used. This fixes bugs where an attribute has differing GNU and Declspec spellings, but they are treated as the same. Eg) __declspec(aligned) when it should be __attribute__((aligned)), and __attribute__((align)) when it should be __declspec(align).

llvm-svn: 199144

__forceinline is a keyword, and not a GNU-style attribute. This FIXME appears to be out-dated, and the attribute syntax is becoming more important these days.

llvm-svn: 199143

Updating the attribute declarations to have the correct syntaxes. This means giving a __declspec spelling to: deprecated, naked, noinline, noreturn, and nothrow. uuid has no GNU spelling, so it was switched to __declspec. dllexport and dllimport both are now supported with GNU spellings.

llvm-svn: 199142

There is no such thing as __attribute__((align)); that's a __declspec attribute. Fixing these test cases to use the proper spelling for their syntax.

adjustFallThroughCount isn't a good name, and the documentation was
even worse. This commit attempts to clarify what it's for and when to
use it.
