This is more resilient, since we want to be able to add more information behind the address point of type objects, and also makes IR a lot less cluttered. The start of the metadata object is now an internal "full metadata" symbol.
Note that we can't do this for known opaque metadata from the C++ runtime, since clang doesn't have a good way to emit offset symbol aliases, so for non-nominal metadata objects we still emit an adjustment inline.

The new option -Womit-needless-words finds places where names are
redundant with type information, producing warnings and Fix-Its to
shorten the names. Part of rdar://problem/22232287, to help bring
the same heuristics we're applying in the Clang importer to the user's
Swift code.
Swift SVN r31234
Sink the actual logic for omitting needless words way down into
Basic, so we can re-use it elsewhere. Tie the Clang importer into that
logic, mapping Clang types down to strings appropriately. NFC

This way they can be used from other projects, like LLDB. The downside
is we now have to make sure the header is included consistently in all
the places we care about, but I think in practice that won't be a problem,
especially not with tests.

The demangler recently regressed to not printing any context
names, including nominal type contexts. This means that symbols
like Optional.init where only printed as init. Continue printing
contexts but not modules (per the original simplified demangling
design).
rdar://problem/19312992
Swift SVN r31066
Break up "Simplified" demangling mode (shortened demangled descriptions
for the sake of displaying in UI with small areas) into more
fine-grained options instead of an opaque "Simplified" option and
provide a static preset of options for displaying stack traces in
Xcode UI and other tools, for example.
- Don't print unmangled suffixes
- Don't print module names
- Shorten various generic specialization descriptions as just
"specialized"
- Don't display long protocol conformances
- Truncate where clauses
- Don't display so-called "entity" types
- Shorten "partial apply *"
- Shorten thunk phrases
- Shorten value witness phrases
- Truncate archetype references

These will be used for reflection, and eventually to speed up generic
operations on single payload enums as well.
Progress on <rdar://problem/21739870>.

...and add a static_assert to OptionSet to enforce it. There are two holes
allowed: if it's not an enum class, the default operator| is acceptable, and
if it /is/ an enum class, not defining operator| is also acceptable. We may
want to tighten this up later.
No functionality change.
Swift SVN r30207
Leave the qualification off of enum cases and type names when 'print'-ing them, but keep them on 'debugPrint'. (At least, at the outermost level; since ad-hoc printing of structs and tuples uses debugPrint, we'll still get qualification at depth, which kind of sucks but needs more invasive state management in print to make possible.) Implements rdar://problem/21788604.

This enables dead argument elimination to be paired with @owned -> @guaranteed
optimization. It has the additional advantage of allowing us to potentially
eliminate additional retains, releases since the fact that the use is dead
implies that the lifetime of the value no longer needs to be live across the
function call.
Since dead argument elimination can be composed with @owned -> @guaranteed, I
had to modify the mangler, remangler, demangler, to be able to handle a mangling
that combines the two.
I just saw noise in the perf test suite.

Due to inreased use of llvm::make_range in LLVM headers and ADL for
types defined in the swift namespace, some of the LLVM headers started
to trigger ambiguity errors between llvm::make_range and
swift::make_range.

sequence which can be read with a forward iterator.
This will be useful for storing access paths to metadata or
protocol conformance values, which are typically very short.
Now with a fix to directly include <climits> for CHAR_BIT.
This was being transitively included on Darwin, but that's
not portable.

Our hack to generate a unique name by appending the class pointer doesn't produce a stable class name that can persist in NSKeyedArchiver, or eventually be used as a key for dynamic runtime instantiation. Generate a proper mangled name for the class instance by building a demangling AST from the metadata nodes and feeding it into the remangler. Should fix rdar://problem/18884563, though I need to try using an archiver with a generic class to verify.
Swift SVN r29316
Now that we are using OptionSetType for option sets, all the support for
doing things the old way can die.
Note: the fix-it that used to apply to RawOptionSetType, it seemed to me,
should still apply to OptionSetType, so I switched it over instead of
removing it.
Swift SVN r29066
This changes things like Swift.Dictionary<Swift.Int, Swift.AnyObject> to Dictionary<Int, AnyObject>
It has been suggested that playgrounds would benefit from not showing the fully qualified name.
Playgrounds use the runtime demangler to obtain type names, and honestly, I do not see enough value in those qualifiers being printed out to justify hackery in PlaygroundLogger or separate demangling logic

We already do for the iOS simulator and the tvOS simulator. This fixes
the 'unrecognized selector sent to instance’ bridging crashes in the stdlib
watch simulator tests.
Greg Parker did the hard work of tracking this down and suggested the fix.
<rdar://problem/20932146>
Swift SVN r28846
To support UI applications displaying demangled names in a limited
amount of screen space, provide a new SwiftDemangle API and Demangler
option to do the following:
- Skip all module name prefixes when printing contexts
- Don't print implicit self/metatype parameters when printing
function types
Add a '-simplified' flag to swift-demangle to support testing at the
command line.
Swift SVN r28727
Share the logic we use to map archetype depth-index pairs to friendly unique names like 'A', 'B', so that demangle generic signatures are still somewhat readable, and so that archetype references into outer contexts with interface type manglings still make sense. Change the remangler to mangle archetypes and dependent generic params using nested index nodes instead of trying to parse the depth and index from the arbitrary names we give them.
Swift SVN r28343
Configure the runtime to build with -Wglobal-constructors, and Lazy-fy almost everything that gets flagged. (I gave "swift_isaMask" a pass since that's almost definitely hot enough to warrant a static initialization.) Make some improvements to the Lazy wrapper, using aligned_storage to ensure that it's trivially constructed and destructed.
Swift SVN r28199
The __lldb_expr modules are special as in they are autogenerated by LLDB and meant to not be user-accessible, so showing them adds visual noise for no user benefit
I am open to the notion of adding a flag to swift-demangle to the same effect, but that seems much lower priority
Swift SVN r28195
Equivalent to llvm::sys::fs::rename, except that if the destination file
exists and has the same contents as the source file, the source file is
simply deleted and the destination file is not touched.

Replace ReST-flavored documentation comments with Markdown.
rdar://problem/20180412
In addition to full Markdown support, the following extensions are
supported. These appear as lists at the top level of the comment's
"document". All of these extensions are matched without regard to
case.
Parameter Outlines
------------------
- Parameters:
- x: ...
- y: ...
Separate Parameters
-------------------
- parameter x: ...
- parameter y: ...
- Note:
Parameter documentation may be broken up across the entire comment,
with a mix of parameter documentation kinds - they'll be consolidated
in the end.
Returns
-------
- returns: ...
The following extensions are also list items at the top level, which
will also appear in Xcode QuickHelp as first-class citizens:

These match most of the extra fields in Doxygen, plus a few more per request.
Other changes
-------------
- Remove use of rawHTML for all markup AST nodes except for those
not representable by the Xcode QuickHelp XSLT - <h>, <hr/>, and of
course inline/block HTML itself.
- Update the doc comment RNG schema to more accurately reflect Xcode
QuickHelp.
- Clean up cmark CMake configuration.
- Rename "FullComment" to "DocComment"
- Update the Swift Standard Documentation (in a follow-up commit)
- Update SourceKit for minor changes and link against cmark
(in a follow-up commit).

Replace the 'ignoreMissing' boolean flag with a new option set type,
SubstOptions, which is easier to extend. It is not an OptionSet<>
because a follow-on commit will introduce a non-trivial option that
will require more storage.
Also eliminate the LazyResolver parameter, which is no longer
needed. Eliminate the silly TypeChecker::substType(), whose only
purpose was to provide the resolver.
