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
The -enable-omit-needless-words option attempts to omit needless words
from method names imported from Clang. Broadly speaking, a word is
needless if it merely restates the type of the corresponding parameter,
using reverse camel-case matching of the type name to the
function/parameter name. The word "With" is also considered needless
if whether follows it is needless, e.g.,
func copyWithZone(zone: NSZone)
gets reduced to
func copy(zone: NSZone)
because "Zone" merely restates type information and the remaining,
trailing "With" is also needless.
There are some special type naming rules for builtin Objective-C types,
e.g.,
id -> "Object"
SEL -> "Selector"
Block pointer types -> "Block"
as well as some very-Cocoa-specific matching rules, e.g., the type
"IndexSet" matches the name "Indexes" or "Indices".
Expect a lot of churn with these heuristics; this is part of
rdar://problem/22232287.

...and always serialize -working-directory for Clang. (But allow it to be
overridden by a later -Xcc -working-directory.)
Not having this has caused plenty of headaches for the debugger, which is the
primary client of this information. We can still get into bad situations with
search paths that don't exist at all (say, when a built framework is transferred
to another computer), but at least we won't fall over in multi-project workspaces.
This isn't an actual command-line option for a few reasons:
- SourceKit is still using frontend options directly, and they'll need something
like this to fix rdar://problem/21912068.
- We might want to be more formal about passing this to Clang.
- I don't actually like the existence of such an option for users.
We can revisit this later if the scales tip. Fixing the debugging issue is the
priority.

Compute the hash of all interface tokens when parsing; write the
interface hash to the swiftdeps file, or if the -dump-interface-hash
option is passed to the frontend. This hash will be used in incremental
mode to determine whether a file's interface has changed, and therefore
whether dependent files need to be rebuilt in response to the change.

This should have no functionality change, but is supposed to keep us from
accidentally relying on the "full" Clang importer when in a backend job.
I tested it by archiving a little iOS app from a developer.
Unfortunately, part of the motivation here was that we'd get error messages when
we pass something Clang doesn't like, and that doesn't seem to be happening.

The value is set based on the -O command-line option. It is generally useful if SIL optimization passes can check the current optimization level.
A couple of subsequent commits are going to make use of this information.
Swift SVN r29653
The test that it's guarding is cheap enough to do all the time, and we
don't have any interesting configurations where it's not set any more.

This frontend option allows one to turn off autolinking to the
specified framework. This general capability is motivated by
rdar://problem/21246363, where we need to turn off some autolinking in
our overlays due to internal vs. public SDK differences.
Swift SVN r29393
I was always confused by the inconsistency of -sil-print-all and the other -sil-print options.
So I thought it would be a good idea to make -sil-print-all also an llvm option.
Together with some other internal options which are only used in the pass manager.

The last remaining case was apparently @objc generic classes, which
seem to work now.
Also nuke the IRGen/unimplemented_objc_generic_class.swift test,
this is now implemented and we have other tests that test this
functionality.

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.

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
Instead of only honoring the last occurrence of -import-module, the frontend now
honors all occurrences of -import-module, making all of the modules specified on
the command line implicitly visible.
This fixes <rdar://problem/20422696>.
Swift SVN r27299
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.

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.

In particular, this is problematic when libraries are loaded dynamically, and
may have newer deployment targets than the main executable.

...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.

Up to now we've been assuming that we have only one 32-bit target and
one 64-bit target per platform. There is a need to be able to build
armv7s for iOS, but assumptions abound in the organization of files per
architecture - tests, cmake targets, and installation.
- Build armv7s when building for iOS
- Use the actual architecture name, not blank or "/32" in all paths
related to architecture.
Testing: Clean buildbot incremental RA tests pass (requires a test
update in SourceKit as well).

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.

This flag indicates that internal APIs within the module should be made
available to client code for testing purposes. Currently does nothing.
Not ready for developer consumption yet, ergo a hidden frontend-only flag.

Make this diagnostic a little nicer in other ways, too:
- Highlight the whole attribute (including the at-sign).
- Don't hardcode the string "objc".
