The generality of the `AvailabilityContext` name made it seem like it
encapsulates more than it does. Really it just augments `VersionRange` with
additional set algebra operations that are useful for availability
computations. The `AvailabilityContext` name should be reserved for something
pulls together more than just a single version.
ValueDecl::isInterfacePackageEffectivelyPublic is used to check if a package decl in
interface file can be skipped for typecheck; if the decl is inlinable and in public or
private interface, it should be allowed to skip. This PR adds a missing check which
looks up the Interface source kind.

Back off treating local lets of tuple type as "initializable", expanding
on the narrow carve-out from #74133. Without this, we would reject local
lets of tuple type that are initialized piecemeal.
Fixes rdar://135028163.
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
Replace the existing C++ implementation of extractInlinableText with
a new implementation based on swift-syntax. It uses SwiftIfConfig to
remove inactive regions (with a special mode), and a new compiler-only
entrypoint in the library to remove comments and `#sourceLocation`.
Allow any declaration to be marked with `@unsafe`, meaning that it
involves unsafe code. This also extends to C declarations marked with
the `swift_attr("unsafe")` attribute.
Under a separate experimental flag (`DisallowUnsafe`), diagnose any
attempt to use an `@unsafe` declaration or any unsafe language feature
(such as `unowned(unsafe)`, `@unchecked Sendable`). This begins to
define a "safe" mode in Swift that prohibits memory-unsafe constructs.
In this PR i worked on replacing the word accessor in diagnostics with more user-facing terminologies like setter, getter, didSet Observer, and members based on the context of the message.
in some messages i didn't need to pass DescriptiveDeclKind instead i just changed the text copy itself.
i also updated tests, so you might find it easier to check my changes this way.
Please let me know if there's something i should've done in a better way, and request changes if needed. !
i can squash my commits after reviewing getting the PR Reviewed, just to make it easier to be checked commit by commit
Resolves#55887
`@unknown default` in switch statements are required for resilient enums since they
might be modified with new fields in the future and modules defining the enums are
generally not built together with the consuming modules.
However, if the modules are in the same package, they are required to be built together,
thus the requirement for `@unknown default` can be skipped. This PR removes the need for
that, enabling less boilerplate. Note this change only impacts typecheck and not SIL gen.
Resolves rdar://130015149.
Upstreams the necessary changes to compile references to `@backDeployed`
declarations correctly when a `macabi` target triple or a `-target-variant` is
specified.
