The SDK overlays have been provided in the Apple SDKs for many years, and the interface and implementation has diverged in more recent years such that trying to build the Swift version no longer works. Remove all of the dead code.

... that would import that as a result of importing Darwin from the SDK.
Amend my previous change to Differentiation and Distributed in this
sense.

Mostly this just means adding `Musl` as a module dependency of various
things and making sure that we build things for `swift_static` even
if `SWIFT_BUILD_STATIC_STDLIB` isn't enabled.
There's also a slight difference in the declaration of `memcmp()`;
musl's declaration is more like the one we have on Darwin.

This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
NDK 26 renamed the directory in which it places the Android compiler-rt from
`lib64/`, and added a bunch of nullability annotations to the Bionic libc.
This patch goes through and adds zippering and the swift module
dependencies to a bunch of pieces of the swift runtimes. Here's to
hoping I hit everything that needed to be hit. :D
With this patch, I'm seeing the appropriate modules under
lib/swift/maccatalyst, so things seem to be working right.
This change adds support for WASI in stdlib tests. Some tests that expect a crash to happen had to be disabled, since there's currently no way to observe such crash from a WASI host.
This is for the 'freestanding' build to stop assuming the platform has argc/argv.
- Introduce a new sub-library, libswiftCommandLineSupport.a
- Move stubs/CommandLine.cpp into this library
- Conditionally embed it into libswiftCore
- Conditionally embed it into libswiftPrivateLibcExtras if not in libswiftCore to support testing
- Add SWIFT_STDLIB_HAS_COMMANDLINE CMake (and build-script) flag
This replaces swiftMSVCRT with swiftCRT. The big difference here is
that the `visualc` module is no longer imported nor exported. The
`visualc` module remains in use for a singular test wrt availability,
but this should effectively remove the need for the `visualc` module.
The difference between the MSVCRT and ucrt module was not well
understood by most. MSVCRT provided ucrt AND visualc, combining pieces
of the old MSVCRT and the newer ucrt. The ucrt module is what you
really wanted most of the time, however, would need to use MSVCRT for
the convenience aliases for type-generic math and the deprecated math
constants.
Unfortunately, we cannot shadow the `ucrt` module and create a Swift SDK
overlay for ucrt as that seems to result in circular dependencies when
processing the `_Concurrency` module.
Although this makes using the C library easier for most people, it has a
more important subtle change: it cleaves the dependency on visualc.
This means that this enables use of Swift without Visual Studio for the
singular purpose of providing 3 header files. Additionally, it removes
the need for the installation of 2 of the 4 support files. This greatly
simplifies the deployment process on Windows.
Clean up a few general patterns that are now obviated by canImport
This aligns more generally with the cleanup that the Swift Package
Manager has already done in their automated XCTest-plumbing tool in
apple/swift-package-manager#1826.
Commit for CMake and build scripts to recognize OpenBSD. To keep this
commit relatively short, this just deals with the rather simple and
uncontroversial changes to the build system.
Note that OpenBSD calls "x86_64" as "amd64", Since the Swift stdlib will
be put in a subdirectory named after ARCH, to ensure the standard
library is properly found later, we use the native architecture name for
OpenBSD in the build system rather than trying to deal with the
difference the other way around.
These should hopefully all be uncontroversial, minimal changes to deal
with progressing the build to completion on OpenBSD or addressing minor
portability issues. This is not the full set of changes to get a
successful build; other portability issues will be addressed in future
commits.
Most of this is just adding the relevant clauses to the ifdefs, but of
note in this commit:
* StdlibUnittest.swift: the default conditional in _getOSVersion assumes
an Apple platform, therefore the explicit conditional and the relevant
enums need filling out. The default conditional should be #error, but
we'll fix this in a different commit.
* tgmath.swift.gyb: inexplicably, OpenBSD is missing just lgammal_r.
Tests are updated correspondingly.
* ThreadLocalStorage.h: we use the pthread implementation, so it
seems we should typedef __swift_thread_key_t as pthread_key_t.
However, that's also a tweak for another commit.
There are situations where you want to build against a libc that is out
of tree or that is not the system libc (Or for cross build scenarios).
This is a change for passing the -sdk and include paths for things like
this.
In the Android paths of the spawnChild function, the parent was creating
a pipe that was never closed, which led to FD starvation. In some tests
with a lots of expected crashes, the childs will not spawn anymore since
the linker would not have enough descriptors to open the shared
libraries, while in other tests which closed the child descriptors as
part of the last test, the parent process will hang waiting those
descriptors to be closed, which will never had happened.
The solution is implement the missing parts of the code, which tried to
read from the pipe in the parent side (using select and read, taking
pieces from other parts of the code). This should match the fork/execv
path used by Android and Haiku to the spawn code used by the rest of the
platforms.
This change fixes StdlibUnittest/Stdin.swift,
stdlib/InputStream.swift.gyb,
stdlib/Collection/FlattenCollection.swift.gyb and
stdlib/Collection/LazyFilterCollection.swift.gyb, which were the last 4
tests failing in Android AArch64.
This allows the conversion of the Windows `BOOL` type to be converted to
`Bool` implicitly. The implicit bridging allows for a more ergonomic
use of the native Windows APIs in Swift.
Due to the ambiguity between the Objective C `BOOL` and the Windows
`BOOL`, we must manually map the `BOOL` type to the appropriate type.
This required lifting the mapping entry for `ObjCBool` from the mapped
types XMACRO definition into the inline definition in the importer.
Take the opportunity to simplify the mapping code.
Adjust the standard library usage of the `BOOL` type which is now
eclipsed by the new `WindowsBool` type, preferring to use `Bool`
whenever possible.
Thanks to Jordan Rose for the suggestion to do this and a couple of
hints along the way.
Magic symbols of the form $ld$install_name$os9.0$@rpath/libswiftCore.dylib tell the linker to use that install name when targeting that OS version. Use these symbols to specify an @rpath install name for all back-deployment libraries when targeting watchOS 2.0-5.1, iOS 7.0-12.1, and macOS 10.9-10.14.

The key thing here is that all of the underlying code is exactly the same. I
purposely did not debride anything. This is to ensure that I am not touching too
much and increasing the probability of weird errors from occurring. Thus the
exact same code should be executed... just the routing changed.
Cygwin is considered a distinct target with a distinct ABI, environment
conditions, and data types. Though the goal of the project is
native Windows integration with UNIX-likes, that is not compatible with
the idea that the platform can be ignored as Win-like enough to have the
existing os(Windows) condition apply.
These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
- CYGWIN symbol is used to distinguish Cygwin environment from other OS
and other environment in Windows.
- Added windows and windowsCygnus to OSVersion in StdlibUnittest
[test] Add a timeout to runRaceTest(). Use it to limit test AtomicInt.swift.
This cuts AtomicInt.swift's execution time from several hours to
about ten minutes on slow hardware and slow build configurations.
