It replaces `DeclAttr::getUnavailable()` and `AvailableAttr::isUnavailable()`
as the designated way to query for the attribute that makes a decl unavailable.
The renamed decl is now stored exclusively in the split request evaluator
storage, which is more efficient since most availability attributes do not
specify a renamed decl.
Code review identified some incorrect UNIMPLEMENTED_CLONEs in DeclAttribute (thank you
Hamish and Rintaro). Fix those, and make sure this can't happen again by checking the type
signatures of clone() in every DeclAttribute subclass.
@lifetime(target: source1, source2...) where target can be any
parameter or 'self'. We cannot have @lifetime attributes with duplicate targets.
Also, update the internal data structures. Previously LifetimeEntry stored
pairwise (target, source) dependencies. Now, LifetimeEntry will store an optional
target descriptor and an array of source descriptors.
Some requirement machine work
Rename requirement to Value
Rename more things to Value
Fix integer checking for requirement
some docs and parser changes
Minor fixes
When printing the public `.swiftinterface` for a `-library-level=api` module,
skip emitting `@available`, `@backDeployed`, and `@_originallyDefinedIn`
attributes that reference "SPI" platforms.
Resolves rdar://133990140.
Upstreams the necessary changes to compile references to `@backDeployed`
declarations correctly when a `macabi` target triple or a `-target-variant` is
specified.
Although I don't plan to bring over new assertions wholesale
into the current qualification branch, it's entirely possible
that various minor changes in main will use the new assertions;
having this basic support in the release branch will simplify that.
(This is why I'm adding the includes as a separate pass from
rewriting the individual assertions)
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 implementation of `#if hasAttribute(...)` only accepted declaration
attributes. It should also accept type attributes, like `@retroactive`.
