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
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
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.
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
SIL seems to be doing the right thing here already, which is great!
Part of rdar://problem/17732115. We'll be able to really see this working
with the next change: allowing references to testable things when using
"@testable import".
Swift SVN r26473
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
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.

Together with -wmo it enables multi-threaded compilation.
I didn't want to reuse the -j option for this, because -num-threads (even if n == 1) does change the generated code.
For details see commit message of r25930.
Swift SVN r26258
With -embed-bitcode, we will invoke swift twice, once to generate the bitcode
file, the second time to perform code generation on the bitcode file.
For now, -embed-bitcode causes -incremental builds to not be incremental,
because of potential issues of mixing the two.

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 adds the -profile-coverage-mapping option to swift, and teaches
SILGenProfiling to generate mappings from source ranges to counters.
Swift SVN r25266
This adds the -profile-generate flag, which enables LLVM's
instrumentation based profiling. It implements the instrumentation
for basic control flow, such as if statements, loops, and closures.
Swift SVN r25155
We've had a rash of bugs due to inconsistencies between how IRGen and the runtime think types are laid out. Add a '-verify-type-layout' mode to the frontend that causes IRGen to emit a bunch of code that compares its static assumptions against what the runtime value witness does.
Swift SVN r24918
This implicitly adds the named module as an import of every source file
in the module being compiled. This is not intended to be used generally,
but will be useful for playgrounds.

Swift SVN r24905
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.
Swift SVN r24705
There's also a testing option, -serialize-debugging-options, to force this
extra info to be serialized even for library targets. In the long run we'll
probably write out this information for all targets, but strip it out of
the "public module" when a framework is built. (That way it ends up in the
debug info's copy of the module.)
Incidentally, this commit includes the ability to add search paths to the
Clang importer on the fly, which is most of rdar://problem/16347147.
Unfortunately there's no centralized way to add search paths to both Clang
/and/ Swift at the moment.

If certain command-line arguments change, the results of the last
compilation aren't reusable, i.e. we can't do an incremental build.
Do a full rebuild when we detect that this happens.
(Which command-line options? Conservatively assume all of them, /except/
those with the new DoesNotAffectIncrementalBuild flag in Options.td.)

of 'bin/swift-update' with the related frontend options.
'swift-update' will be the tool for producing diffs to update swift code to the
latest version.

This flag enables one to specify a json file that expresses a specific
pipeline in the following format:
[
[
"$PASS_MANAGER_ID",
"run_n_times"|"run_to_fixed_point",
$NUM_ITERATIONS,
"$PASS1", "$PASS2", ...
],
...
]
This will make it easier to experiment with different pass pipelines by
allowing:
1. Automatic generation of pass pipelines without needing to recompile
the compiler itself.
2. Simple scripting of pass pipelines via the json meta language.
3. Enabling the easy expression and reproducability of a specific
pipeline ordering via radar.
In the next commit I will provide a python library for the generation of these
json files with a few types of pipeline generators already created.
Swift SVN r24055
...and then honor them.
While here, make -l a little more flexible (see interpret_with_options test).

This is a hidden frontend-only option intended for debugging purposes,
mainly for identifying where in a file the type checker is spending most
of its time. Use with "sort -g" to get the top problem functions.

This does not have any tests since I am going to start going through SILGen
tests and updating them for guaranteed self as the appropriate tests.
*NOTE* There is more work to be done in terms of thunks, but the basic
functionality is done.

Add -whole-module-optimization option as synonym of
-force-single-frontend-invocation (for now). Add support for
-output-file-map when using -whole-module-optimization with multiple
input files -- the key for the single output file's map is the empty string.
