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.

I'm not quite sure how to tickle this one, but the next commit adds more
data after the cached header, at which point existing tests break. This
could have already caused problems if no padding was needed in the bitstream.

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 regresses a bit on the diagnostic when a submodule is missing, as well
as missing out on Clang's automatic typo correction, but it does avoid putting
the Clang CompilerInstance into an error state, which is important for the
REPL. It's also not entirely clear that Clang had the right behavior in this
case either---we'd get a module back, but if the particular submodule we
asked for didn't exist we might get its parent. We can revisit this later.

i.e. don't look for attributes on an @class somewhere.
Also do this for tag decls, whose attributes propagate forwards until there's
a definition.

This makes sure that the Clang CompilerInstance doesn't think that we've seen
an error just because we were checking for the existence of a module, and
therefore will not break the world when the module is absent.
This fixes an issue where loading PlaygroundLogger broke static inline
functions because PlaygroundLogger has no Objective-C module.

It also lays groundwork for not treating a missing module as a fatal error
in REPL modes. To do that properly, however, we should figure out how to do
this for submodules as well. <rdar://problem/17994094>

This handles things like NSSwapHostLongLongToBig and MKMapRectMake that
are static inline functions that themselves call other static inline
functions.

Background: if a Clang module /only/ imports submodules from another module,
we would lose all re-exports from that other module, because we're treating
all decls as part of the top-level module. This actually shows up with UIKit
and QuartzCore due to some weirdness in how the QuartzCore module is set up
(see <rdar://problem/17888079>), resulting in 'CALayer' not being visible
with just 'import UIKit'.
Workaround (this patch): treat Clang imports just like Swift imports: if the
submodule is referenced, so is the top-level module. This isn't great, but
it's not really any more awful than the rest of our Clang modules story.

This is already a fatal error, so it doesn't matter how many diagnostics we
dump after that. It's better not to lie to the rest of the compiler about
whether the load succeeds.
No immediate Radar, but this fixes a crash in the test case I'm about to
commit, and possibly some other mystery "dependency missing" crashes in
XREF resolution.

...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".

If importing a Clang module fails, we should report that at the location of
the import statement. This doesn't do that fully because it isn't transitive
(if Swift module Foo imports Swift module Bar, which fails to import Clang
module Baz, we don't get an error in user source), but it's a step forward
for the simple cases.

This allows us to express required initializers in the API notes. Use
it to smooth over NSString differences in the various SDKs even more.

We choose not to model "OptionalTypeAdjustment(1, OTK_Optional)" in yaml, so update the known methods to use what we can model.
Introduce the absence of nullability info and use it to set NullabilityAudited and NumAdjustedNullable. (Maybe, after the .def file is gone and we have more testing, we could change the KnownObjCMethod API to better reflect the yaml format..)

Specifically, handle them by also importing the top-level module. This is
unfortunate, but at least lets people /access/ things in explicit submodules,
even if it doesn't let them limit their import to a specific submodule.
(swift) import OpenGL.GL3
(swift) glGetString
// r0 : (GLenum) -> ConstUnsafePointer<GLubyte> = (Function)
(swift) OpenGL.glGetString
// r1 : (GLenum) -> ConstUnsafePointer<GLubyte> = (Function)
One unfortunate side effect of having a single Clang ASTContext is that if
one Swift module imports a Clang submodule, every Swift module can now see
it. That means /mixing/ incompatible submodules, such as OpenGL.GL and
OpenGL.GL3, still won't work. Filed <rdar://problem/17756745> for that.

To do this, we keep track of decls with superfluous typedefs (rather than
just the typedefs), and check for that. Tag decls without typedefs are
printed with the tag.

directly into Decl and get rid of the "getMutableAttrs" nonsense.

Make the "merging class-wide information into method information"
operation part of ObjCMethodInfo. It doesn't belong in the Clang
importer.

Now that bridging headers from ASTs are always present and bridging headers
from the command line are checked in advance, we no longer need to worry
about the Clang instance failing to find the bridging header. That's good,
because this wasn't implemented correctly anyway: if a bridging header
imported a module, we could get an error.
Swift SVN r20129
We do this so that the swiftmodule file contains all info necessary to
reconstruct the AST for debugging purposes. If the swiftmodule file is copied
into a dSYM bundle, it can (in theory) be used to debug a built app months
later. The header is processed with -frewrite-includes so that it includes
any non-modular content; the user will not have to recreate their project
structure and header maps to reload the AST.
There is some extra complexity here: a target with a bridging header
(such as a unit test target) may depend on another target with a bridging
header (such as an app target). This is a rare case, but one we'd like to
still keep working. However, if both bridging headers import some common.h,
we have a problem, because -frewrite-includes will lose the once-ness
of #import. Therefore, we /also/ store the path, size, and mtime of a
bridging header in the swiftmodule, and prefer to use a regular parse from
the original file if it can be located and hasn't been changed.

We're not using this for anything, yet, so there aren't any checked-in
tests. Also note that I'm using ".apinotesc" for the binary form of

This is a hack to work around two issues:
- <iso646.h>, which defines macros for "and", "or", and "not" (among other
things) is an implicit submodule of Darwin.
- Macros even in explicit submodules are leaking out when the parent module
is imported <rdar://problem/14870036>.
There's no actual reason to require <iso646.h> in SDK header files -- it
should be a user-level choice whether or not to use those names. And
selectors with "and", "or", and "not" in them should not be mangled by this.
So, as a hack, we define the header guards that <iso646.h> uses ahead of
time, so that the file will be ignored. We do this for /both/ variants of
<iso646.h> on our system (Clang's and /usr/include's) just to be safe.
