The stdlib build for wasm target is failing on Darwin host due to
default values of some CMake options on Darwin host. We need to
explicitly define these options to make the build pass.
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.
The WASI community is transitioning to a new naming for the "preview"
version in the target triple: wasm32-wasi -> wasm32-wasip1.
At this moment, we keep the old triple wasm32-wasi because it's already
widely used, but we should start using the new triple threaded target.
LLVM checks only if the OS field *starts* with "wasi", so "wasip1" is
still considered a valid `isOSWASI()` target.

This patch adds a `-threads` variant of the Wasm stdlib build, which
has completely different ABI and target triple. Now we build
non-threaded and threaded variants when `--build-wasm-stdlib` is
enabled.
Now that the compilation model of noncopyable types is enabled everywhere,
and one can enable the feature for specific modules, we no longer need a
separate build-script/CMake option to enable it globally. Remove it all.
With this build-script has a flag --enable-experimental-nonescpable-types=1
to enable this feature in stdlib.
Also we can now add // REQUIRES: nonescapable_types to tests which run only when
the compiler is built with this feature turned on.
This patch allows running executable tests with WasmKit. If WasmKit is
not built, fall back to running only non-executable tests. Also add
stdlib and Concurrency executable tests to run.
This patch adds a new product, WasmKit, which is a Wasm runtime that is
going to be used to run executable tests targeting Wasm. Note that the
product is not shipped as a part of the toolchain, but is used only for
testing purposes.
This library uses GenericMetadataBuilder with a ReaderWriter that can read data and resolve pointers from MachO files, and emit a JSON representation of a dylib containing the built metadata.
We use LLVM's binary file readers to parse the MachO files and resolve fixups so we can follow pointers. This code is somewhat MachO specific, but could be generalized to other formats that LLVM supports.

This patch introduces `--enable-experimental-noncopyable-generics` for
the build script. It replaces
`--swift-stdlib-experimental-noncopyable-generics`
The old build option only enables the feature when building the
stdlib, but if we've built the stdlib with NoncopyableGenerics, the
compiler should be hardwired to have that feature enabled, too.
This patch also introduces the `noncopyable_generics` lit parameter, so
that tests assuming the system was built with the feature can live
in-tree and be tested, if they specify `REQUIRES: noncopyable_generics`.
