-nostdimport and -nostdlibimport only remove the toolchain and usr/lib/swift search paths, and they leave the framework search paths intact. That makes it impossible to get a fully custom SDK environment. Make their behavior match clang's -nostdinc/-nostdlibinc behavior: treat framework and non-framework paths the same. In other words, -nostdinc removes *all* compiler provided search paths, and -nostdlibinc removes *all* SDK search paths.
Rename SkipRuntimeLibraryImportPaths to SkipAllImportPaths, and ExcludeSDKPathsFromRuntimeLibraryImportPaths to SkipSDKImportPaths to reflect their updated behavior.
Move the DarwinImplicitFrameworkSearchPaths handling from SearchPathOptions to CompilerInvocation, where RuntimeLibraryImportPaths is managed. Rename it to just ImplicitFrameworkSearchPaths, and filter for Darwin when it's set up so that all of the clients don't have to do Darwin filtering themselves later.

This matches send non sendable but importantly also makes it clear that we are
talking about something that doesn't conform to the Sendable protocol which is
capitalized.

`@unchecked Sendble` is dangerous, and almost always the wrong thing to

Replaces generic `expression is 'async' but is not marked with 'await`
diagnostic with a tailed one for cases where there is an access to an
actor-isolated value outside of its actor without `await` keyword.
This makes the diagnostics for async and sync contexts consistent
and actually identifies a problem instead of simply pointing out
the solution.

Introduce a new ASTWalker option for walking CustomAttrs and use it
for the placeholder scanner to ensure we can expand placeholders in
attribute arguments.
- Extend `@_inheritActorContext` attribute to support optional `always` modifier.
The new modifier will make closure context isolated even if the parameter is not
captured by the closure.
- Implementation `@_inheritActorContext` attribute validation - it could only be
used on parameter that have `@Sendable` or `sending` and `@isolated(any)` or
`async` function type (downgraded to a warning until future major Swift mode
to avoid source compatibility issues).
- Add a new language feature that guards use of `@_inheritActorContext(always)` in swift interface files
- Update `getLoweredLocalCaptures` to add an entry for isolation parameter implicitly captured by `@_inheritActorContext(always)`
- Update serialization code to store `always` modifier

Adopters of the new Span and MutableSpan types should not encounter information
about an experimental feature when they attempt to use these types in
unsupported ways, such as simply returning them from a function.

Not used (yet), but needed to implement SIMD.replacing(with:where:)
idiomatically, and probably useful otherwise.
**Explanation:** Makes select available in Swift's builtin module, which
allows implementing concrete SIMD operations more efficiently.
**Risk:** Low. New builtin protected by a feature flag, currently
unused.
**Testing:** New tests added.

Otherwise querying this clang module, e.g. from the corresponding Swift overlay's underlying module import, will fail, since no such module exists.

The diagnostic can outlive the locally constructed attribute, which was
passed by pointer, if there is an active `DiagnosticTransaction`.
(cherry picked from commit f4e49d5a0a)
When defaulting to main-actor isolation, types that have synthesized
conformances (e.g., for Equatable, Hashable, Codable) were getting
nonisolated members by default. That would cause compiler errors
because the conformances themselves defaulted to main-actor isolation
when their types were.
Be careful to only mark these members as 'nonisolated' when it makes
sense, and leave them to get the isolation of their enclosing type
when the conformance might have isolation. This ensures that one can
use synthesis of these protocols along with default main-actor mode.
There is a one-off trick here to force the synthesized CodingKeys to
be nonisolated, because the CodingKey protocol requires Sendable.
We'll separately consider whether to generalize this rule.

When we discover a textual module dependency which is a module which was not originally built from source using C++ interop (specifying '-formal-cxx-interoperability-mode=off'), avoid looking up the C++ standard library Swift overlay for it. This is required for the case of the 'Darwin' module, for example, which includes headers which map to C++ stdlib headers when the compiler is operating in C++ interop mode, but the C++ standard library Swift overlay module itself depends on 'Darwin', which results in a cycle. To resolve such situations, we can rely on the fact that Swift textual interfaces of modules which were not built with C++ interop must be able to build without importing the C++ standard library Swift overlay, so we avoid specifying it as a dependency for such modules.
The primary source module, as well as Swift textual module dependencies which *were* built with C++ interop will continue getting a direct depedency of the 'CxxStdlib' Swift module.

Previously we would insert StringRefs that reference the keys in the

Due to a bug in how macros on nodes imported from clang are evaluated,
their function body is not always type checked. This forces type
checking before silgen of a macro originating on a node imported from
clang, to prevent crashing in silgen.

string interpolation method with a `default:` parameter for optional
interpolation values.

Testing: New tests for the string interpolations and fix-its.
This includes changing the feature name so that compilers with the experimental feature don’t accidentally pick up content that only works in the final version.
Resolves rdar://150065196.
It has indirect effects on the accessors, so it shouldn’t matter, but we can defensively redirect the query to the API counterpart anyway.
This was the last `InferredInABIAttr` attribute, so we can now remove all of the infrastructure involved in supporting attribute inference.
Inlinability doesn’t affect the mangling except in function specializations, which are applied after the fact and should never mangle in information from an ABI-only decl. That means we can simply ban these from `@abi` instead of inferring them.
Also adds some assertions to help double-check that SIL never tries to directly mangle or retrieve inlinability info from an ABI-only decl.
SwiftSyntaxParser is already doing this, and we already diagnosed it in Sema anyway, so we’re just moving that diagnostic earlier so the ASTGen testing mode is happy. Also adding compiler tests for it.
Macro-related tests are not included in this commit; they require matching swift-syntax changes which are being negotiated.
CustomAttr backs four different features, each of which requires a different behavior in `@abi`:
• Global actors: Permitted (and permitted to vary) since they can affect mangling
• Result builders: Forbidden inside an `@abi` since they have no ABI impact
• Property wrappers: Forbidden both inside an `@abi` and on a decl with an `@abi` since it’s not clear how we would apply `@abi` to the auxiliary decls
• Attached macros: Forbidden inside an `@abi` since an ABI-only decl has no body, accessors, members, peers, extensions, or (currently) conformances
Implement these behaviors (outside of `ABIDeclChecker` since they can’t be described there).
Macro-related tests are not included in this commit; they require matching swift-syntax changes which are being negotiated.
With `ARCMigrate` and `arcmt-test` removed from clang in
https://github.com/llvm/llvm-project/pull/119269 and the new code
migration experience under way (see
https://github.com/swiftlang/swift-evolution/pull/2673), these options
are no longer relevant nor known to be in use. They were introduced
long ago to support fix-it application in Xcode.
For now, turn them into a no-op and emit a obsoletion warning.
