This allows script mode to pick up the current version of macOS
instead of defaulting to 10.9, making it unnecessary to write #available.
A -target flag can still override this if you're trying to write a
portable script.
The logic is a little tortured to avoid having to actually link to
Foundation.framework or libobjc.
Finishes rdar://problem/29433205.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
This refactoring is groundwork for saving the cross-module dependencies
in the swiftdeps files as well, so that we know to rebuild files if an
outside file changes (such as a bridging header, another framework's
headers, or another framework's swiftmodule).

This allows swiftFrontend to drop its dependency on swiftDriver, and could
someday allow us to move the integrated frontend's option parsing out of
swiftFrontend (which would allow other tools which use swiftFrontend to
exclude the option table entirely).
Swift SVN r19824
This performs very conservative dependency generation for each compile task
within a full compilation. Any source file, swiftmodule, or Objective-C
header file that is /touched/ gets added to the dependencies list, which
is written out on a per-input basis at the end of compilation.
This does /not/ handle dependencies for the aggregated swiftmodule, swiftdoc,
generated header, or linked binary. This is just the minimum needed to get
Xcode to recognize what needs to be rebuilt when a header or Swift source
file changes. We can revisit this later.
This finishes <rdar://problem/14899639> for now.
Swift SVN r18045
- Added support for invoking the Swift frontend via "swift_driver -frontend".
- Added frontend_main.cpp, which implements the main entry point for the
integrated frontend. (Currently, this supports compiling an input Swift file
into an object file.)
- Removed lib/Frontend/FrontendOptions.td, and replaced its functionality with
options in include/Swift/Driver/Options.td and a new
include/Swift/Driver/FrontendOptions.td. Options supported by the frontend
are denoted by the FrontendOption flag; options which are not supported by
the driver are denoted by the NoDriverOption flag.
- Updated CompilerInvocation::parseArgs() to use the option table returned from
createDriverOptTable(), including renaming a handful of options. (-triple is
now -target, and -Xclang is now -Xcc.)
Swift SVN r11082
This closes out <rdar://problem/14513108> -- sil-opt no longer depends on
ClangImporter or any Clang libraries. In theory, however, forcing a load
of a libSwiftClangImporter.dylib would allow sil-opt to process SIL files
containing Clang imports.
