PrintAsClang is supposed to emit declarations in the same order regardless of the compiler’s internal state, but we have repeatedly found that our current criteria are inadequate, resulting in non-functionality-affecting changes to generated header content. Add a diagnostic that’s emitted when this happens soliciting a bug report.
Since there *should* be no cases where the compiler fails to order declarations, this diagnostic is never actually emitted. Instead, we test this change by enabling `-verify` on nearly all PrintAsClang tests to make sure they are unaffected.
This did demonstrate a missing criterion that only mattered in C++ mode: extensions that varied only in their generic signature were not sorted stably. Add a sort criterion for this.
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: ...

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).

This is required to correctly use the mock SDK when the SDK overlay is
built and tested separately. (Otherwise, the mock SDK might not get
used, because the overlay SDK options would expand from the
%-substitution, appear first on the command line, and shadow the mock
SDK in the search path).
Swift SVN r25185
Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
Swift SVN r24504
Doing so is safe even though we have mock SDK. The include paths for
modules with the same name in the real and mock SDKs are different, and
the module files will be distinct (because they will have a different
hash).
This reduces test runtime on OS X by 30% and brings it under a minute on
a 16-core machine.
This also uncovered some problems with some tests -- even when run for
iOS configurations, some tests would still run with macosx triple. I
fixed the tests where I noticed this issue.

As part of this change, start testing generated headers under
-Weverything -Werror, with targeted exceptions.

Swift SVN r22010
The upshot of this is that internal decls in an app target will be in the
generated header but internal decls in a framework target will not. This
is important since the generated header is part of a framework's public
interface. Users always have the option to add members via category to an
internal framework type they need to use from Objective-C, or to write the
@interface themselves if the entire type is missing. Only internal protocols
are left out by this.
The presence of the bridging header isn't a /perfect/ way to decide this,
but it's close enough. In an app target without a bridging header, it's
unlikely that there will be ObjC sources depending on the generated header.
