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:
- Attention: ...
- Author: ...
- Authors: ...
- Bug: ...
- Complexity: ...
- Copyright: ...
- Date: ...
- Experiment: ...
- Important: ...
- Invariant: ...
- Note: ...
- Postcondition: ...
- Precondition: ...
- Remark: ...
- Remarks: ...
- See: ...
- Since: ...
- Todo: ...
- Version: ...
- Warning: ...
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.

Update tests to match, and rewrite SwiftPrivatePthreadExtras to take advantage of native C function pointer support instead of hacking it up through a stub C++ library.

Keep track of a second set of "direct method reference" curry thunks that don't end in a dynamic dispatch in order to properly implement a partial application such as 'let foo = super.foo'. Fixes rdar://problem/20598526.
Swift SVN r27538
When -enable-simd-import is active, if we encounter a vector type, try to load the SIMD Swift module, and if successful, map float, double, and int vectors to SIMD.{Float,Double,Int}N types if they exist.
Swift SVN r27367
This works around a big performance regression in code completion
performance that was introduced with r25741. This hack does not work
completely correctly with multiple file builds, but a) this should be a
minor issue for enum code completions, and b) this simply returns to the
pre-25741 behaviour. This hack should disappear when we fix
rdar://problem/20047340.
For rdar://problem/20445407.
Swift SVN r27320
Previously, the only way to get initializers was completing after the
name of the type:
Foo#^complete_here^#
Foo(#^or_here^#
And now it will also work in unadorned expressions:
#^a_top_level_completion^#
bar(a, #^walked_into_a_bar^#
Unfortunately, not all our clients handle this well yet, so it's
protected by a language option.

Enable checking for uses of potentially unavailable APIs. There is
a frontend option to disable it: -disable-availability-checking.
This commit updates the SDK overlays with @availability() annotations for the
declarations where the overlay refers to potentially unavailable APIs. It also changes
several tests that refer to potentially unavailable APIs to use either #available()
or @availability annotations.
Swift SVN r27272
Remove the suppression of deprecation and potential unavailability diagnostics in
synthesized functions. We still suppress some explicit unavailability diagnostics -- those
in synthesized functions in synthesized functions that are lexically contained in
declarations that are themselves annotated as unavailable. For these cases, the right
solution <rdar://problem/20491640> is to not synthesize the bodies of these functions in
the first place.
rdar://problem/20024980
Swift SVN r27203
To use members of protocol extensions on existential types, we
introduce an OpenExistentialExpr expression to open up the existential
type (into a local archetype) and perform the operations on that local
archetype.
Unlike with uses of initializers or dynamic-Self-producing
methods of protocols, which produce similar ASTs, we have the type
checker perform the "open" operation and then track it through
constraint application. This scheme is better (because it's more
direct), but it's still using a simplistic approach to deciding where
the actual OpenExistentialExpr goes that needs improvement.
Swift SVN r26964
We're not going to require the type parameters to be redeclared on
extensions of generic types, so take away the staging option and
diagnostic.
Swift SVN r26854
In particular, this is problematic when libraries are loaded dynamically, and
may have newer deployment targets than the main executable.
Swift SVN r26786
...which allows "@testable import" to work with modules not compiled for
testing. This isn't generally safe, but should be fine for clients like
SourceKit which just need to have the API available and might not be able
to properly rebuild the original target for testing.
We may revisit this in the future.
Swift SVN r26629
This flag enables checking of availability (deprecation, explicit unavailability,
and potential unavailability) in synthesized functions. The flag will go away once this
checking is fully staged in.
Swift SVN r26624
This warning is temporarily going being a flag so that, once it is safe to place generic parameters on extensions of generic types, we can opt-in to update our code when it is convenient.
Swift SVN r26416
- Add frontend and standard library build support for tvOS.
- Add frontend support for watchOS.
watchOS standard library builds are still disabled during SDK bring-up.
To build for TVOS, specify --tvos to build-script.
To build for watchOS, specify --watchos to build-script (not yet supported).
This patch does not include turning on full tests for TVOS or watchOS, and
will be included in a follow-up patch.
Swift SVN r26278
This makes it easier to diff and read SIL output. Since it is behind the -emit-sorted-sil
flag, there is no effect on normal compilation.
Swift SVN r26101
This is at the expense of blockquotes, which we don't actually need at
the moment. All blockquotes get interpreted as preformatted code.
Swift SVN r25459
This is just good to do and hopefully will help prevent people from forgetting
to check in the future by annotating the API explicitly as returning a
potentially nullptr.
Swift SVN r25364
Since a function pointer doesn't carry any context, we can only form a C function pointer from a static reference to a global function or a context-free local function or closure. (Or maybe a static function applied to its metatype, but that's not handled here yet.) As a placeholder for a to-be-bikeshedded surface syntax, let the existing @cc(cdecl) attribute appear in source text when the -enable-c-function-pointers frontend flag is passed.
Swift SVN r25308
This lets us disambiguate the symbols for static and instance properties, and enables us to eventually leave the useless "self" type mangling out of method symbols. Fixes rdar://19012022 and dupes thereof, including crasher #1341.
Swift SVN r25111
Specifically:
1. Use std::enable_if to enforce that the passed in collection's iterator is a
random access iterator.
2. Add comment that explains that the container must have an erase method that
can remove a range of items specified by a random access iterator.
Swift SVN r25015
This helper function takes in a vector-like object and then performs:
std::sort(v.begin(), v.end());
v.erase(std::unique(v.begin(), v.end()), v.end());
Swift SVN r25003
If a subclass overrides methods with variance in the optionality of non-class-type members, emit a thunk to handle wrapping more optional parameters or results and force-unwrapping any IUO parameters made non-optional in the derived. For this to be useful, we need IRGen to finally pay attention to SILVTables, but this is a step on the way to fixing rdar://problem/19321484.
