Dan Gohman 947c9af774 Experimental TBAA support.
This enables metadata generation by default, however the TBAA pass
in the optimizer is still disabled for now.

NAKAMURA Takumi 11f6be1ce8 lib/CodeGen/CodeGenModule.cpp: DLLImportLinkage should be processed also on declaration.
It enables clang to compile Mingw's headers.

Daniel Dunbar 8caf6415a8 Add support for attribute((naked)), patch by Zoxc on cfe-commits!

Douglas Gregor ec3bec0c7a Kill FunctionDecl's IsCopyAssignment bit; it duplicated what could
already be determined by isCopyAssignmentOperator(), and was set too
late in the process for all clients to see the appropriate
value. Cleanup only; no functionality change.

This lets us remove Sema.h's dependency on Expr.h and Decl.h.

John McCall 614dbdcd55 Go back to asking CodeGenTypes whether a type is zero-initializable.
Make CGT defer to the ABI on all member pointer types.
This requires giving CGT a handle to the ABI.
It's way easier to make that work if we avoid lazily creating the ABI.
Make it so.

John McCall 86353416a7 The ARM C++ ABI is sufficiently different from the Itanium C++ ABI that
it deserves its own enumerator.  Obviously the implementations should
closely follow the Itanium ABI except in cases of divergence.

Charles Davis 6bcb07ad71 Add some enum goodness as requested by Chris. Now instead of storing the
active C++ ABI as a raw string, we store it as an enum. This should improve
performance somewhat.

And yes, this time, I started from a clean build directory, and
all the tests passed. :)

Alexis Hunt dcfba7b35b Generate Attr subclasses with TableGen.
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.

John McCall b3732bb3b7 Just disable the hidden-visibility optimization for now by hiding it behind
a -cc1 option.  The Darwin linker complains about mixed visibility when linking
gcc-built objects with clang-built objects, and the optimization isn't really
that valuable.  Platforms with less ornery linkers can feel free to enable this.

John McCall 5513fce96b It turns out that linkers (at least, the Darwin linker) don't necessarily
do the right thing with mixed-visibility symbols, so disable the visibility
optimization where that's possible, i.e. with template classes (since it's
possible that an arbitrary template might be subject to an explicit
instantiation elsewhere).  447.dealII actually does this.

I've put the code under an option that's currently not hooked up to anything.

John McCall e16adc2b1e Emit standard-library RTTI with external linkage, not weak_odr.
Apply hidden visibility to most RTTI;  libstdc++ does not rely on exact
pointer equality for the type info (just the type info names).  Apply
the same optimization to RTTI that we do to vtables.

Fixes PR5962.

Argyrios Kyrtzidis c81af03fb3 Merge PCHWriterDecl.cpp's isRequiredDecl and CodeGenModule::MayDeferGeneration into a new function,
DeclIsRequiredFunctionOrFileScopedVar.

This is essentially a CodeGen predicate that is also needed by the PCH mechanism to determine whether a decl
needs to be deserialized during PCH loading for codegen purposes.
Since this logic is shared by CodeGen and the PCH mechanism, move it to the ASTContext,
thus CodeGenModule's GetLinkageForFunction/GetLinkageForVariable and the GVALinkage enum is moved out of CodeGen.

This fixes current (and avoids future) codegen-from-PCH bugs.
