Default value for `Category` for serialization purposes is
an empty string but it should be handled as `nil` while
bridging because category name cannot be empty when present.
To pave the way for the new experimental feature which will operate on '@const' attribute and expand the scope of what's currently handled by '_const' without breaking compatibility, for now.
Bridge the category name and educational note computed for the Swift
compiler's diagnostics to the newly-introduced category field for
the swift-syntax diagnostics. This lets the swift-syntax renderer
introduce the category name and (optionally) link to the
documentation.
Delay resolution of availability domain identifiers parsed in availability
specifications until type-checking. This allows custom domain specifications to
be written in `if #available` queries.
With the acceptance of SE-0458, allow the use of unsafe expressions, the
@safe and @unsafe attributes, and the `unsafe` effect on the for..in loop
in all Swift code.
Introduce the `-strict-memory-safety` flag detailed in the proposal to
enable strict memory safety checking. This enables a new class of
feature, an optional feature (that is *not* upcoming or experimental),
and which can be detected via `hasFeature(StrictMemorySafety)`.
Memory unsafety in the iteration part of the for-in loop (i.e., the part
that works on the iterator) can be covered by the "unsafe" effect on
the for..in loop, before the pattern.
It wraps an type-checked `AvailabilitySpec`, which guarantees that the spec has
a valid `AvailabilityDomain` associated with it. This will unblock moving
AvailabilitySpec domain resolution from parsing to sema.
Parse expanded buffer into dedicated syntax.
Also rename `BridgedGeneratedSourceFileKindAttribute` to
`BridgedGeneratedSourceFileKindAttributeFromClang` because C++ decl
(i.e. `GeneratedSourceInfo::Kind::AttributeFromClang`) was renamed a
while ago.
* Collect flag in `ParamDecl::setTypeRepr()`.
* [ASTGen] Separate `BridgedParamDecl.setTypeRepr(_:)` from
`BridgedParamDecl.createParsed(_:)` aligning with C++ API. The majority
of the creations don't set the typerepr.
* Update `ParamSpecifierRequest::evaluate` to handle non-implicit
`ParamDecl` without `TypeRepr` (i.e. untyped closure parameter), instead
of `setSpecifier(::Default)` manually in Parse.
Rework TypeAttribute bridging facilities.
Eliminate the _fake_ `swift::TypeAttributes`, but just use the normal
`BridgedArrayRef` for briding the attribute list. Introduce
`BridgedTypeOrCustomAttr` tagged pointer which resembles
`swift::TypeOrCustomAttr`.
To help older compilers that don't yet support the unsafe expression
deal with the Swift interface files we produce, remove the "unsafe" from
expressions in inlinable code.
