Anton Korobeynikov 231e875b5c Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or
AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86.

In particular, all library functions should always be AAPCS regardless of floating point ABI used.

Douglas Gregor 20b2ebd785 Implement a new 'availability' attribute, that allows one to specify
which versions of an OS provide a certain facility. For example,

  void foo()
  __attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6)));

says that the function "foo" was introduced in 10.2, deprecated in
10.4, and completely obsoleted in 10.6. This attribute ties in with
the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that
we want to deploy back to Mac OS X 10.1). There are several concrete
behaviors that this attribute enables, as illustrated with the
function foo() above:

  - If we choose a deployment target >= Mac OS X 10.4, uses of "foo"
    will result in a deprecation warning, as if we had placed
    attribute((deprecated)) on it (but with a better diagnostic)
  - If we choose a deployment target >= Mac OS X 10.6, uses of "foo"
    will result in an "unavailable" warning (in C)/error (in C++), as
    if we had placed attribute((unavailable)) on it
  - If we choose a deployment target prior to 10.2, foo() is
    weak-imported (if it is a kind of entity that can be weak
    imported), as if we had placed the weak_import attribute on it.

Naturally, there can be multiple availability attributes on a
declaration, for different platforms; only the current platform
matters when checking availability attributes.

The only platforms this attribute currently works for are "ios" and
"macosx", since we already have -mxxxx-version-min flags for them and we
have experience there with macro tricks translating down to the
deprecated/unavailable/weak_import attributes. The end goal is to open
this up to other platforms, and even extension to other "platforms"
that are really libraries (say, through a #pragma clang
define_system), but that hasn't yet been designed and we may want to
shake out more issues with this narrower problem first.

Addresses <rdar://problem/6690412>.

As a drive-by bug-fix, if an entity is both deprecated and
unavailable, we only emit the "unavailable" diagnostic.

John McCall 86bc21ffcf Provide an attribute, objc_method_family, to allow the inferred family
of an Objective-C method to be overridden on a case-by-case basis.  This
is a higher-level tool than ns_returns_retained &c.;  it lets users specify
that not only does a method have different retain/release semantics, but
that it semantically acts differently than one might assume from its name.
This in turn is quite useful to static analysis.

John McCall c146582e60 When parsing an out-of-line member function declaration, we must delay
access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method.  This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.

We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope.  Making us delay regardless of context exposed several bugs with
how we were manipulating delay.  I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.

I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema;  this is a pattern we might want to consider rolling
out to other components of Sema.

Jeffrey Yasskin 08a4f8f197 Add an attribute to forbid temporary instances of a type. This allows class
authors to write

people from doing things like creating a scoped_lock that only lives for a
single statement instead of an entire scope.

Peter Collingbourne b331b267b1 Sema: support for processing non-inheritable declaration attributes early
llvm-svn: 123960
2011-01-21 02:08:45 +00:00
John McCall 3882ace207 Refactor the application of type attributes so that attributes from
the declaration-specifiers and on the declarator itself are moved
to the appropriate declarator chunk.  This permits a greatly
simplified model for how to apply these attributes, as well as
allowing a much more efficient query for the GC attribute.
Now all qualifier queries follow the same basic strategy of
"local qualifiers, local qualifiers on the canonical type,
then look through arrays".  This can be easily optimized by
changing the canonical qualified-array-type representation.

Do not process type attributes as decl attributes on declarations
with declarators.

When computing the type of a block, synthesize a prototype
function declarator chunk if the decl-spec type was not a
function.  This simplifies the logic for building block signatures.

Change the logic which inserts an objc_read_weak on a block
literal to only fire if the block has a __weak __block variable,
rather than if the return type of the block is __weak qualified,
which is not actually a sensible thing to ask.

Chandler Carruth 743682bb9f Re-work the handling of implicit 'this' arguments and silly GCC-style attribute
argument indexes. This handles the offsets in a consistent manner for all of
the attributes which I saw working with these concepts. I've also added tests
for the attribute that motivated this: nonnull.

I consolidated the tests for format attributes into one file, and fleshed them
out a bit to trigger more of the warning cases. Also improved the quality of
some of the diagnostics that occur with invalid argument indices.

The only really questionable change here is supporting the implicit this
argument for the ownership attribute. I'm not sure it's really a sensible
concept there, but implemented the logic for consistency.

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.

tests working attributes instead of broken ones. I plan to add more tests here
for non-dependent attributes in a subsequent patch.

John McCall ab26cfa58d Standardize the parsing of function type attributes in a way that
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().
