There were no clients and it leaks information about the developer's system.
After this commit, there should be no full paths present in framework modules.
(App modules may contain search paths for debugging reasons, as well as a
full or relative path to the bridging header.)
Swift SVN r24851
Local type declarations are saved in the source file during parsing,
now serialized as decls. Some of these may be defined in DeclContexts
which aren't Decls and previously weren't serialized. Create four new
record kinds:
* PatternBindingInitializer
* DefaultArgumentInitializer
* AbstractClosureExpr
* TopLevelCodeDecl
These new records are used to only preserve enough information for
remangling in the debugger, and parental context relationships.
Finally, provide a lookup API in the module to search by mangled name.
With the new remangling API, the debugging lifecycle for local types
should be complete.
The extra LOCAL_CONTEXT record will compressed back down in a
subsequent patch.

There's also a testing option, -serialize-debugging-options, to force this
extra info to be serialized even for library targets. In the long run we'll
probably write out this information for all targets, but strip it out of
the "public module" when a framework is built. (That way it ends up in the
debug info's copy of the module.)
Incidentally, this commit includes the ability to add search paths to the
Clang importer on the fly, which is most of rdar://problem/16347147.
Unfortunately there's no centralized way to add search paths to both Clang
/and/ Swift at the moment.

This isn't being used for much yet, but it will allow us to tell whether
something is an app target even at the module-merging stage, which is a
better way to tell if something is an app than whether it has a bridging
header.
We'll also need this if we ever take advantage of reusing "partial modules"
(serialized ASTs for other parts of the module that aren't affected by the
current source file) for compiling source files in incremental builds;
unfortunately that's unlikely given our dependency model.

Refuse to load a module if it was compiled for a different architecture or
OS, or if its minimum deployment target is newer than the current target.
Additionally, provide the target triple as part of pre-loading validation
for clients who care (like LLDB).

Locally scoped type declarations were previously not serialized into the
module, which meant that the debugger couldn't reason about the
structure of instances of those types.
Introduce a new mangling for local types:
[file basename MD5][counter][identifier]
This allows the demangle node's data to be used directly for lookup
without having to backtrack in the debugger.
Local decls are now serialized into a LOCAL_TYPE_DECLS table in the
module, which acts as the backing hash table for looking up
[file basename MD5][counter][identifier] -> DeclID mappings.
New tests:
* swift-ide-test mode for testing the demangle/lookup/mangle lifecycle
of a module that contains local decls
* mangling
* module merging with local decls

a non-native owner. This is required by Slice, which
will use an ObjC immutable array object as the owner
as long as all the elements are contiguous.
As part of this, I decided it was best to encode the
native requirement in the accessor names. This makes
some of these accessors really long; we can revisit this
if we productize this feature.
Note that pinning addressors still require a native
owner, since pinning as a feature is specific to swift
refcounting.
Swift SVN r24420
Change all the existing addressors to the unsafe variant.
Update the addressor mangling to include the variant.
The addressor and mutable-addressor may be any of the
variants, independent of the choice for the other.
SILGen and code synthesis for the new variants is still
untested.

This reverts commit dc98e17d84b991b6be8b8feb5e0d05aad24f52a4.
I believe this commit was causing test failures on:
IRGen/c_layout.sil
IRGen/existentials.sil
It also recreates the file lib/Serialization/ModuleFormat.h,
which really can't have been intended.
Swift SVN r23732
Adding explicit constructors to Clang-imported structs in the previous commits exposes a latent phase ordering issue between the Clang importer and SIL deserialization. Deserializing the standard library SIL ends up pulling in additional Clang decls which never get type-checked before we attempt to emit their code. Work around this by bringing back the "EagerDeserializedDecls" block in the serialization format, and adding any cross-referenced decls that get referenced in SILSerializeAll mode to it, so that we ensure they're available before SILGen. We also have to type-check external decls after doing so, since when only importing a module, we wouldn't do any type-checking at all otherwise.
Swift SVN r23728
Before this patch there was no dependence visible to the optimizer between a
open_existential and the witness_method allowing the optimizer to reorder the
two instruction. The dependence was implicit in the opened archetype but this
is not a concept model by the SIL optimizer.
%2 = open_existential %0 : $*FooProto to $*@opened("...") FooProto
%3 = witness_method $@opened("...") FooProto,
#FooProto.bar!1 : $@cc(...)
%4 = apply %3<...>(%2)
This patch changes the SIL representation such that witness_methods on opened
archetypes take the open_existential (or the producer of the opened existential)
as an operand preventing the optimizer from reordering them.
%2 = open_existential %0 : $*FooProto to $*@opened("...") FooProto
%3 = witness_method $@opened("...") FooProto,
#FooProto.bar!1,
%2 : $*@opened("...") FooProto : $@cc(...)
%4 = apply %3<...>(%2)

This is necessary for @objc enums because, for C compatibility, the representations of the cases must match their raw values. We might want to do this for sufficiently fragile Swift enums in the future too, but that can wait. This lets us successfully print the raw values as ObjC.
Swift SVN r23423
Include a mapping from Objective-C selectors to the @objc methods that
produce Objective-c methods with those selectors. Use this to lazily
populate the Objective-C method lookup tables in each class. This makes
@objc override checking work across Swift modules, which is part of
rdar://problem/18391046.
Note that we use a single, unified selector table, both because it is
simpler and because it makes global queries ("is there any method with
the given selector?") easier.
Swift SVN r23214
@objc methods, initializers, deinitializers, properties, and
subscripts all produce Objective-C methods. Diagnose cases where two
such entities (which may be of different kinds) produce the same
Objective-C method in the same class.
As a special exception, one can have an Objective-C method in an
extension that conflicts with an Objective-C method in the original
class definition, so long as the original class definition is from a
different model. This reflects the reality in Objective-C that the
category definition wins over the original definition, and is used in
at least one overlay (SpriteKit).
This is the first part of rdar://problem/18391046; the second part
involves checking that overrides are sane.
Swift SVN r23147
Modeling builtins as first-class function values doesn't really make sense because there's no real function value to emit, and modeling them this way complicates passes that work with builtins because they have to invent function types for builtin invocations. It's much more straightforward to have a single instruction that references the builtin by ID, along with the type information for the necessary values, type parameters, and results, so add a new "builtin" instruction that directly represents a builtin invocation. NFC yet.

properties.
The main design change here is that, rather than having
purportedly orthogonal storage kinds and has-addressor
bits, I've merged them into an exhaustive enum of the
possibilities. I've also split the observing storage kind
into stored-observing and inherited-observing cases, which
is possible to do in the parser because the latter are
always marked 'override' and the former aren't. This
should lead to much better consideration for inheriting
observers, which were otherwise very easy to forget about.
It also gives us much better recovery when override checking
fails before we can identify the overridden declaration;
previously, we would end up spuriously considering the
override to be a stored property despite the user's
clearly expressed intent.

Doug had changed the comment but not the implementation -- we were still
serializing the containing module rather than the declaring nominal or
