This commit adds a function to remap the clang arguments passed
during compilation. This is intented to be shared across the
Swift compiler and LLDB to apply path remapping for debug info
paths.
This commit refactors the way ASTs are being built in SourceKit and how `SwiftASTConsumer`s are served by the built ASTs. `SwiftASTManager.h` should give an overview of the new design.
This commit does not change the cancellation paradigm in SourceKit (yet). That is, subsequent requests with the same `OncePerASTToken` still cancel previous requests with the same token. But while previously, we were only able to cancel requests that haven’t started an AST build yet, we can now also cancel the AST build of the to-be-cancelled requests.
With this change in place, we can start looking into explicit cancellation of requests or other cancellation paradigms.
"add inits to toplevel" and "call pattern heuristics" are only used in
code completion. Move them from LangOptions to CodeCompletionContext so
that they don't affect compiler arguments.
Changed the frontend flag to -enable-experimental-lexical-lifetimes from
-enable-experimental-defined-lifetimes.
Changed the attribute on begin_borrow from [defined] to [lexical].
Serialize the canonical name of the SDK used when building a swiftmodule
file and use it to ensure that the swiftmodule file is loaded only with
the same SDK. The SDK name must be passed down from the frontend.
This will report unsupported configurations like:
- Installing roots between incompatible SDKs without deleting the
swiftmodule files.
- Having multiple targets in the same project using different SDKs.
- Loading a swiftmodule created with a newer SDK (and stdlib) with an
older SDK.
All of these lead to hard to investigate deserialization failures and
this change should detect them early, before reaching a deserialization
failure.

Remove the option that explicitly enables concurrency back-deployment,
and instead always enable its support in the compiler. Remove the use
of the extraneous CMake option as well.
When enabling the build of the back-deployable concurrency library via
the build-script option `--back-deploy-concurrency`, also build the
compiler and (main) concurrency library to support older deployment targets.
Building the compiler for older deployment targets is effectively the
same as implicitly passing
`-Xfrontend -enable-experimental-back-deploy-concurrency`. That option
should probably go away.
Building the primary _Concurrency library for back-deployment means
setting the "SwiftStdlib 5.5" availability back to the earlier
deployment targets. This should have no effect on how the _Concurrency
library binary is built, but it does ensure that the right
availability annotations are in the _Concurrency module.
Add a frontend-only flag `-enable-experimental-back-deploy-concurrency`
to be used to stage in the back deployment of concurrency. At present,
all it does is lower the availability minimums for use of concurrency
features.
This hidden frontend option lets us be more lax
when type-checking in the presence of editor
placeholders by treating them as holes during
constraint solving.
* Rename --enable-experimental-opaque-return-types and gate structural opaque types with a flag
* Separate out structural opaque type result builder tests
In order to put constraints on opaque types in function returns, we want to
support naming them like 'func f() -> <T> T { }'. This commit parses that
syntax into the new `OpaqueReturnParameteriedTypeRepr`. This is hidden behind
the new flag --enable-experimental-opaque-return-types.
There are two pieces here:
- A -warn-on-potentially-unavailable-enum-case flag is passed down by
the driver when *producing* a swiftinterface
- When *consuming* a swiftinterface, also enable this behavior
Part of rdar://problem/78306593.
Before this change, we always use the Swift target triple to instantiate the internal
Clang instance. When loading a Swift module from the textual interface, we may pick up
a lower target triple to use to build the Swift module because the target is hard-coded
in the textual interface file. This implies we may end up building multiple versions of the
same Clang module, one for each target triple of the loading Swift module.
This change adds a new frontend flag -clang-target to allow clients to specify a
consistent clang target to use across the Swift module boundaries. This value won't change
because it's not part of .swiftinterface files.
swift-driver should pass down -clang-target for each frontend invocation, and its value should be
identical to -target.

The CMake option `SWIFT_ENABLE_EXPERIMENTAL_CONCURRENCY` was originally
meant to imply that we should build the _Concurrency module, which it still
does. However, to support minimal stdlib builds, it also became a way
to configure the compiler to avoid implicitly importing the
_Concurrency module. However, we build configurations of Swift where
we want the implicit import but don't want to build the _Concurrency
library. Use a new, different option
(`SWIFT_IMPLICIT_CONCURRENCY_IMPORT`) for the "implicit import"
behavior within the compiler, which defaults to "true", and disable
that for minimal stdlib builds.

For various reasons, it can be useful/interesting to create builds of
Swift that minimize dependencies. Let's try to keep that working as long
as we can.
Intro the concept of library access or distribution level to identify
layers of libraries and report public imports of private libraries from
public ones.
