This completes the FileUnit refactoring. A module consists of multiple
FileUnits, which provide decls from various file-like sources. I say
"file-like" because the Builtin module is implemented with a single
BuiltinUnit, and imported Clang modules are just a single FileUnit source
within a module.
Most modules, therefore, contain a single file unit; only the main module
will contain multiple source files (and eventually partial AST files).
The term "translation unit" has been scrubbed from the project. To refer
to the context of declarations outside of any other declarations, use
"top-level" or "module scope". To refer to a .swift file or its DeclContext,
use "source file". To refer to a single unit of compilation, use "module",
since the model is that an entire module will be compiled with a single
driver call. (It will still be possible to compile a single source file
through the direct-to-frontend interface, but only in the context of the
whole module.)

I tried hard find all references to 'func' in documentation, comments and
diagnostics, but I am sure that I missed a few. If you find something, please
let me know.

Previously we would cache the results of operator lookup whether or not the
operator we found came from an imported module. Since different source files
can have different imports, it's not correct to automatically share operators
from imported modules with all files in the translation unit.
This still isn't fully correct; the current logic prefers operators from
local imports over operators implicitly available from other source files.
Swift SVN r9683
There is still plenty of fallout to get everything fully correct, but
right now we can build the standard library and run all the tests in
multiple-file mode.
Swift SVN r9673
docs/Resilience.rst describes the notion of a resilience component:
if the current source file is in the same component as a module being
used, it can use fragile access for everything in the other module,
with the assumption that everything in a component will always be
recompiled together.
However, nothing is actually using this today, and the interface we
have is probably not what we'll want in 2.0, when we actually implement
resilience.
Swift SVN r9174
Right now this is just an extra layer of indirection for the decls,
operators, and imports in a TU, but it's the first step towards compiling
multiple source files at once without pretending they're all in a single
file. This is important for the "implicit visibility" feature, where
declarations from other source files in the same module are accessible
from the file currently being compiled.
Swift SVN r9072
Instead, pass a LazyResolver down through name lookup, and type-check
things on demand. Most of the churn here is simply passing that extra
LazyResolver parameter through.
This doesn't actually work yet; the later commits will fix this.

Introduce an EnumCaseDecl for source fidelity to track the 'case' location and ordering of EnumElementDecls. Parse a comma-separated list of EnumElementDecls after a 'case' token.

...instead of just those that are re-exported. This will be used for
autolinking (and probably few other places).
As part of this, we get two name changes:
(1) Module::getReexportedModules -> getImportedModules
(2) TranslationUnit::getImportedModules -> getImports
The latter doesn't just get modules-plus-access-paths; it also includes
whether or not the import is re-exported. Mainly, though, it just didn't
seem like a good idea to overload this name when the two functions aren't
really related.
No tests yet, will come with autolinking.
Swift SVN r7487
Previously, TypeAliasDecl was used for typealiases, generic
parameters, and assocaited types, which is hideous and the source of
much confusion. Factor the latter two out into their own decl nodes,
with a common abstract base for "type parameters", and push these
nodes throughout the frontend.
No real functionality change, but this is a step toward uniquing
polymorphic types, among other things.
Swift SVN r7345
We never really discussed this and it doesn't really buy us much. If we
want to have a compact way to import many things, it may not even end
up looking like this.
Swift SVN r7015
We can get to these transitively; we should only record what the TU
actually claims to reference.
It turns out that we were still relying on this to force the load of
adapter modules for Clang modules. For now, we just force that up front,
even though currently that also forces the creation of ClangModule
wrappers for all transitive includes.
No intended visible functionality change.

Again, the import kind rules are:
- 'import KIND' can import any decl whose introducer is KIND.
- 'import typealias' can also import a struct, class, or union.
- Conversely, 'import KIND' can import a typealias for a decl whose
introducer is KIND.
- Only functions can be overloaded; anything else counts as an ambiguous
import and is an error.
- If an import statement only imports a single decl, but the user got the
kind wrong, we can issue a fix-it for the kind.
We don't have source locations or synthetic source for declarations yet,
so there are no notes about what's /causing/ the ambiguities. Tracked by
<rdar://problem/14650883>
Swift SVN r6917
Note that the import kind is not checked yet; this is effectively our old
behavior for "import swift.print".
Infrastructure: move Module::forAllVisibleModules out-of-line, and add
makeStackLambda to STLExtras for using a non-escaping lambda with
std::function.
Swift SVN r6852
Our diagnostic message says "no such module 'NAME'". However, if we tried
to import a submodule, the top-level module's name would be used for NAME
and the submodule part dropped. For now, just don't include the name if
importing a submodule.
Swift SVN r6851
This makes it very clean to reason about which part should be used
to find a module to load, and which part should be used to filter
lookup within that module.
This breaks the old "import swift.print" syntax in favor of the new
"import func swift.print", but the new syntax is currently ignored.
Swift SVN r6849
Also, update LangRef.
Note that an explicit "import module" has been left out for now, since
it's not strictly necessary and "module" isn't a keyword yet.
Swift SVN r6786
We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!
Swift SVN r6783
Now that we have true serialized modules, the standard library can import
the Builtin module without any special direction (beyond -parse-stdlib),
and anyone can include those modules without special direction.
Swift SVN r6752
This iterates over a module's exports, transitively, in an unspecified
but deterministic order. This is useful for any sort of lookup and for
managing transitive inclusion. It also allows us to remove the hack in
Sema for loading a Clang module's adapter module, and just rely on the
previous commit.
Swift SVN r6699
This makes it very clear who is depending on special behavior at the
module level. Doing isa<ClangModule> now requires a header import; anything
more requires actually linking against the ClangImporter library.
If the current source file really can't import ClangModule.h, it can
still fall back to checking against the DeclContext's getContextKind()
(and indeed AST currently does in a few places).
Swift SVN r6695
Rather than automatically re-exporting or not re-exporting every import in
a TranslationUnit, we'll eventually want to control which imports are local
(most of them) and which imports are shared with eventual module loaders.
It's probably not worth implementing this for TranslationUnit, but
LoadedModule can certainly do something here.
Currently, a LoadedModule is even more permissive than a TranslationUnit:
all imports are re-exported. We can lock down on this once we have a
re-export syntax.
Swift SVN r6523
This eliminates the duplicate IdentifierType resolution code (fixing
<rdar://problem/13946567>), and moves us a step closure to elimining
name binding as a separate pass.
Swift SVN r5940
This causes the SourceLoader to recursively parse the imported module in standard
library mode, giving it access to the Builtin module.
This is all a terrible hack and should be ripped out with great victory someday, but
until we have binary modules that persist the build setting used to produce the
module, this is the best we can do.
Swift SVN r5847

Now the only way you get access to the Builtin module is if you're the standard
library (currently modeled with the -parse-stdlib command line flag, will eventually
be part of build configuration goop or something).
This breaks a few of Jordan's serialization tests, which I've XFAILed after discussion.

of ways non-stdlib and non-sil files have access to the builtin module.

library. We use the same (somewhat broken heuristics), they are
just implemented in another way.
The major functionality change is that previously, .sil files would
auto import "swift" if they started with a non-sil decl. Now they
never do.
