Removes the initWithBool: hack from the Clang importer. We can now
express NSNumber's conformance to the BooleanLiteralConvertible
protocol in the overlay.
Swift SVN r21976
Conforming to BooleanLiteralConvertible now requires
init(booleanLiteral: Bool)
rather than
static func convertFromBooleanLiteral(value: Bool) -> Self
This posed a problem for NSNumber's conformance to
BooleanLiteralConvertible. A class needs a required initializer to
satisfy an initializer requirement, but one cannot add a required
initializer via an extension. To that end, we hack the Clang importer
to import NSNumber's initWithBool with the name
init(booleanLiteral:)
and add back the expected init(bool:) initializer in the
overlay. These tricks make NSNumber even harder to subclass, but we
don't really care: it's nearly impossible to do well anyway, and is
generally a Bad Idea.

Per API review with Ali. While we're here, give the initializer a corresponding 'rawValue' argument label, and change the associated type name to RawValue to match.

We don't want them showing up in SourceKit's generated interface for a module
(e.g. NSInvocation should not actually appear in the ObjectiveC module).
No tests because swift-ide-test prints implicit decls as well as explicit ones.
Swift SVN r21858
This can be used by SourceKit's interface printer to display modules with
forward declarations of classes in dependent modules, e.g. ObjectiveC
forward-declaring Foundation's NSString for use in NSObject. We can consider
doing something similar for C tag types (structs and enums).

Redefine the RawRepresentable protocol to use an 'init?' method instead of 'fromRaw(Raw)', and a 'raw' get-only property instead of 'toRaw()'. Update the compiler to support deriving conformances for enums and option sets with the new protocol. rdar://problem/18216832
Swift SVN r21762
This is a hack that allows us to support accessibility APIs in Swift.
It addresses radar://17509751.
A class might conform to both NSAccessibility (containing accessibility
properties) and individual accessibility protocols (containing
accessibility methods with the same names as the properties). This should
not compile (but currently happens to compile). To avoid the problem down
the road, we import setters and getters instead of the accessibility
properties from NSAccessibility.
Swift SVN r21757
Specifically, it should not ever have a clang::TypedefDecl as its Clang node,
even if the RecordDecl is anonymous and immediately wrapped in a typedef.
It looks like no one was ever doing this intentionally; it's just left over
from before we looked through typedefs at all. This is important because we
use the clang::RecordDecl for IRGen layout if it's present; before this patch
we would fall back to Swift layout for these structs (clearly wrong).
The one exception here is enums -- NS_OPTIONS and named C enums get imported
as structs as well. If we add any other exceptions, we should be sure they
are dealt with in IRGen as well.
The change in the printed interface output is due to the source location
for the Clang node of an NS_ENUM or NS_OPTIONS decl being inside a macro.
I didn't see a quick fix for this, so I'm going to ignore it for now.
Swift SVN r21748
When determining whether one imported initializer stomps on another,
use the parameter types rather than the full type. This prevents
differences in failability from causing ambiguities.
Swift SVN r21692
We currently mangle private declarations exactly like public declarations,
which means that private entities with the same name and same type will
have the same symbol even if defined in separate files.
This commit introduces a new mangling production, private-decl-name, which
includes a discriminator string to identify the file a decl came from.
Actually producing a unique string has not yet been implemented, nor
serialization, nor lookup using such a discriminator.

Introduce an attribute that describes when a given CF type is
toll-free-bridged to an Objective-C class, and which class that
is. Use that information in the type checker to provide the CF <->
Objective-C toll-free-bridged conversions directly, rather than using
the user-defined conversion machinery.

Depending on visitation order, we would occasionally leave the factory
method available if we had completely imported the initializer
first. Fixes <rdar://problem/17261609>.
Swift SVN r21361
In this mode, use nullability information on the result type of the
initializer or factory method to determine failability of the
initializer. This is behind the flag
-enable-objc-failable-initializers until we have the SILGen support in
place.

This is a step towards making the framework easier to use in Swift; in the
actual headers, these are typed as "CFTypeRef" or "const CFTypeRef", which
is not considered Hashable (and thus cannot be put in a dictionary).
Unfortunately, CFStringRef is also not hashable, so we're not there yet,
but at least this allows a freer conversion to NSString.

Nearly all of them come from some annotation written explicitly in the

Previously, we only retained the module in which a normal protocol
conformance occurred, which meant we either had to go searching for
the appropriate extension (yuck) or do without that information. This
is part of the separating-extension-archetypes work.
Swift SVN r20793
The eventual goal for extensions of generic types is to require them
to specify their generic parameters, e.g.,
extension Array<T> { ... }
rather than today's
extension Array { ... }
Start parsing (optional) generic parameters here, and update the
representation of ExtensionDecl to accomodate this new grammar
production. Aside from the parser changes, there's no intended
functionality change here.
Swift SVN r20682
This adds generic parameters and generic signatures to extension
declarations. The actual generic parameters just mirror what is
available on the extended type; however, it is filled in via extension
validation, which is handled lazily.
This is a NFC step toward decoupling the archetypes of extensions from
the archetypes of the extended types <rdar://problem/16974298>.

...rather than distinct classes. This is a bit more complicated than just
making a second typealias because we still want to strip off the "Ref".

Previously, we were just storing setter accessibility via the accessibility
level on the setter function. However, some Stored properties never actually
have a setter synthesized, which led to the compiler dropping the setter
accessibility at serialization time. Rather than try to hack up something
clever, just store the setter accessibility explicitly in every
AbstractStorageDecl. (We still only serialize it for VarDecls, because
settable SubscriptDecls always have setter functions.)

...and 'assign' and 'unsafe_unretained' as 'unowned(unsafe)', if the
property is a class type.
This isn't important for the compiler, but it is documentation for users
when they look at the generated interface for an Objective-C module.
Note that this actually produces a decl users can't yet write:
unowned(unsafe) var foo: UIView!

Initializers for non-final classes will soon need to be 'required' to
conform to an initializer requirement in a protocol, so start
marking imported initializers from Objective-C protocols as
'required'. This is part of <rdar://problem/17408284> and
<rdar://problem/17415607>.
Swift SVN r20428
If an enum has a name but isn't declared with NS_ENUM or NS_OPTIONS, we
don't know how it's intended to be used, so we import it as a struct with
each enumerator as a value. The raw value of the enum used to be accessible
as the 'value' field, but that was mistakenly marked Private in the Great
Access Control Update.
We could consider making plain enums RawRepresentable (and just convert
to and from their raw type without checking anything), but that's something
to do later.
