This is in preparation for wiring up debug info support for noncopyable
values. Originally this flag name made sense since it was set when we performed
consume operator checking. Now I am going to use it for noncopyable types as
well. I think the new name uses_moveable_value_debuginfo actually describes what
the flag is supposed to do, tell IRGen that the value may be moved since it
needs to use moveable value debug info emission.
Calling getImportedModules requires to list the desired kind of imports.
With the new kind of imports this has become cumbersome. Let's simplify
it by offering common sets of imports. Advanced call sites can still
list the desired imports explicitly.
* [Executors][Distributed] custom executors for distributed actor
* harden ordering guarantees of synthesised fields
* the issue was that a non-default actor must implement the is remote check differently
* NonDefaultDistributedActor to complete support and remote flag handling
* invoke nonDefaultDistributedActorInitialize when necessary in SILGen
* refactor inline assertion into method
* cleanup
* [Executors][Distributed] Update module version for NonDefaultDistributedActor
* Minor docs cleanup
* we solved those fixme's
* add mangling test for non-def-dist-actor
This modifies the ClangImporter to introduce an opaque placeholder
representation for forward declared Objective-C interfaces and
protocols when imported into Swift.
In the compiler, the new functionality is hidden behind a frontend
flag -enable-import-objc-forward-declarations, and is on by default
for language mode >6.
The feature is disabled entirely in LLDB expression evaluation / Swift
REPL, regardless of language version.
While a Swift program cannot directly utter one of the unique names
produced by the macro expansion context outside of the macro itself,
utilities such as type reconstruction require the ability to look up
these names. Note that various kinds of macros can introduce unique
names, and update the name lookup facilities for macro-generated names
to account for them.

The previous behavior kept going even after we reported an invalid
swiftmodule. As such it ended up losing the precise invalid reason and
returned Malformed later on.
Allow freestanding macros to be used at top-level.
- Parse top-level `#…` as `MacroExpansionDecl` when we are not in scripting mode.
- Add macro expansion decls to the source lookup cache with name-driven lazy expansion. Not supporting arbitrary name yet.
- Experimental support for script mode and brace-level declaration macro expansions: When type-checking a `MacroExpansionExpr`, assign it a substitute `MacroExpansionDecl` if the macro reference resolves to a declaration macro. This doesn’t work quite fully yet and will be enabled in a future fix.
When loading a swiftmodule A, read its package information to tell if
the current client should load A's dependencies imports by a package
import. Only clients belonging to the same package as A should load
those dependencies, clients outside of the package likely don't have
access to those dependencies.
This is specific to swiftmodules as swiftinterfaces never display a
package-only import. Clients are unaware of package dependencies when
building against a swiftinterface.

Swiftmodules built by a mismatching compiler are loaded if the mismatch
is only on the last digit of the compiler version. In such a case, write
a remark directly to stderr to avoid showing this error in IDE but keep
it for debugging purposes.

`__shared` and `__owned` would always get mangled, even when they don't have any effect
on ABI, making it unnecessarily ABI-breaking to apply them to existing API to make
calling conventions explicit. Avoid this issue by only mangling them in cases where they
change the ABI from the default.
Previously enum AccessLimitKind was
added to distinguish access scopes b/t package and public while keeping
DeclContext null but it proved to be too limiting. This PR creates package specific entries for DeclContext and
ASTHierarchy. It create a new class PackageUnit that can be set as the parent DeclContext of ModuleDecl. This PR
contains addition of such entries but not the use of them; the actual use of them will be in the upcoming PRs.
Resolves rdar://106155600
Provide ASTWalker with a customization point to specify whether to
check macro arguments (which are type checked but never emitted), the
macro expansion (which is the result of applying the macro and is
actually emitted into the source), or both. Provide answers for the
~115 different ASTWalker visitors throughout the code base.
Fixes rdar://104042945, which concerns checking of effects in
macro arguments---which we shouldn't do.
And do a first pass of auditing existing uses of the parameter specifiers to
make sure that we look at the ValueOwnership mapping in most cases instead of
individual modifiers.
Since https://github.com/apple/swift/pull/63178 added support for Clang modules in the explicit module map, it is possible for there to be multiple modules with the same name: a Swift module and a Clang module. The current parsing logic just overwrites the corresponding entry module in a hashmap so we always only preserved the module that comes last, with the same name.
This change separates the parsing of the modulemap JSON file to produce a separate Swift module map and Clang module map. The Swift one is used by the 'ExplicitSwiftModuleLoader', as before, and the Clang one is only used to populate the ClangArgs with the requried -fmodule-... flags.
