22b20afce6 [Distributed] make witness be the distributed thunk 2022-06-27 17:08:55 +09:00

0bb6a7b9e8 SIL: Avoid serializing the bodies of the original copies of @_backDeploy functions to prevent the optimizer from inlining those bodies into their back deployment thunks. This ensures that the copy of the function in the library dylib is reliably called when it is available, both with and without optimizations enabled. Also update the attr_backDeploy_evolution test case to use precondition() instead of assert() since asserts are compiled out with optimizations enabled.

5ab8e0834d [Distributed] Reimplement distributed call thunks completely in AST (#41616)
* [Distributed] dist actor always has default executor (currently)

* [Distributed] extra test for missing makeEncoder

* [DistributedDecl] Add DistributedActorSystem to known SDK types

* [DistributedActor] ok progress on getting the system via witness

* [Distributed] allow hop-to `let any: any X` where X is DistActor

* [Distributed] AST: Add an accessor to determine whether type is distributed actor

- Classes have specialized method on their declarations
- Archetypes and existentials check their conformances for
  presence of `DistributedActor` protocol.

* [Distributed] AST: Account for distributed members declared in class extensions

`getConcreteReplacementForProtocolActorSystemType` should use `getSelfClassDecl`
otherwise it wouldn't be able to find actor if the member is declared in an extension.

* [Distributed] fix ad-hoc requirement checks for 'mutating'

[PreChecker] LookupDC might be null, so account for that

* [Distributed] Completed AST synthesis for dist thunk

* [Distributed][ASTDumper] print pretty distributed in right color in AST dumps

* wip on making the local/remote calls

* using the _local to mark the localCall as known local

* [Distributed] fix passing Never when not throwing

* fix lifetime of mangled string

* [Distributed] Implement recordGenericSubstitution

* [Distributed] Dont add .

* [Distributed] dont emit thunk when func broken

* [Distributed] fix tests; cleanups

* [Distributed] cleanup, move is... funcs to DistributedDecl

* [Distributed] Remove SILGen for distributed thunks, it is in Sema now!

* [Distributed]  no need to check stored props in protocols

* remote not used flag

* fix mangling test

* [Distributed] Synthesis: Don't re-use AST nodes for `decodeArgument` references

* [Distributed] Synthesis: Make sure that each thunk parameter has an internal name

* [Distributed/Synthesis] NFC: Add a comment regarding empty internal parameter names

* [Distributed] NFC: Adjust distributed thunk manglings in the accessor section test-cases

beb2bd2a96 AST: support @_effects attribute with custom strings.
In addition to the predefined cases,  like "readnone", "readonly", etc. support providing a custom string, which will be parsed later.
Also, allow multiple effects attributes to be put onto a function.

431b6661e4 Generate async main entrypoint for top-level
This patch adds the SILGen side of generating the asynchronous main
entrypoint for top-level code. The behavior is the same as with the
asynchronous MainType entrypoint.

552ae0635a Add AsyncEntryPoint SILDeclRef type
The AsyncEntryPoint represents the thunk that is wrapped in a task. This
thunk is used to ensure that the main function explicitly calls "exit",
and to properly unwrap and report any unhandled errors returned from the
user-written main. The function takes on the name `@async_main` in the
emitted SIL.

de7e5efed6 [SILGen] Add SILDeclRef for main entry-point
Allow SILDeclRef to refer to the main program
entry-point, which will either be for a main
SourceFile, or a synthetic main such as an `@main`
decl. Adjust the various SILDeclRef related
functions to handle this new case, and change the
emission to go through `emitFunctionDefinition`.

This change will allow the entry-point for an `@main`
decl (and eventually a main SourceFile) to be
emitted on-demand from its symbol name.

6f5cffbcb9 Mangling: add support for mangling the body-function of asyncHandlers
We don't introduce a new mangling here.
To distinguish the names of the original asyncHandler function and it's generated "body-function", we just mangle the body-function with an async attribute, i.e. as if it was declared as async.
This change is mostly to pass information to the ASTMangler to mangle a not async function as "async".

b994bf3191 Add support for _specialize(exported: true, ...)
This attribute allows to define a pre-specialized entry point of a
generic function in a library.

The following definition provides a pre-specialized entry point for
`genericFunc(_:)` for the parameter type `Int` that clients of the
library can call.

```
@_specialize(exported: true, where T == Int)
public func genericFunc<T>(_ t: T) { ... }
```

Pre-specializations of internal `@inlinable` functions are allowed.

```
@usableFromInline
internal struct GenericThing<T> {
  @_specialize(exported: true, where T == Int)
  @inlinable
  internal func genericMethod(_ t: T) {
  }
}
```

There is syntax to pre-specialize a method from a different module.

```
import ModuleDefiningGenericFunc

@_specialize(exported: true, target: genericFunc(_:), where T == Double)
func prespecialize_genericFunc(_ t: T) { fatalError("dont call") }

```

Specially marked extensions allow for pre-specialization of internal
methods accross module boundries (respecting `@inlinable` and
`@usableFromInline`).

```
import ModuleDefiningGenericThing
public struct Something {}

@_specializeExtension
extension GenericThing {
  @_specialize(exported: true, target: genericMethod(_:), where T == Something)
  func prespecialize_genericMethod(_ t: T) { fatalError("dont call") }
}

bba87cdc10 SIL: Fix witness visibility hack to handle non-serialized declarations.
We have a hack to handle "public" declarations in extensions to internal protcols that are
intended as default implementations for a public protocol that the internal protocol refines.
This hack failed to trigger for synthesized declarations with shared linkage, such as
automatically generated `read` coroutines, causing a visibility assertion failure where we would
try to refer to the non-serializable synthesized declaration from the witness thunk we would
normally consider serialized. Fixes rdar://problem/55846638.

723b2d2cbe [AutoDiff upstream] Add derivative function witness/vtable entry SILGen. (#30569)
`@differentiable` attribute on protocol requirements and non-final class
members now produces derivative function entries in witness tables and vtables.

This enables `witness_method` and `class_method` differentiation.

Existing type-checking rules:

- Witness declarations of `@differentiable` protocol requirements must have a
  `@differentiable` attribute with the same configuration (or a configuration
  with superset parameter indices).
  - Witness table derivative function entries are SILGen'd for `@differentiable`
    witness declarations.

- Class vtable derivative function entries are SILGen'd for non-final
  `@differentiable` class members.
  - These derivative entries can be overridden or inherited, just like other
    vtable entries.

Resolves TF-1212.

aab622e913 [AutoDiff upstream] Add derivative function SILDeclRefs. (#30564)
`@differentiable` attribute on protocol requirements and non-final class members
will produce derivative function entries in witness tables and vtables.

This patch adds an optional derivative function configuration
(`AutoDiffDerivativeFunctionIdentifier`) to `SILDeclRef` to represent these
derivative function entries.

Derivative function configurations consist of:
- A derivative function kind (JVP or VJP).
- Differentiability parameter indices.

Resolves TF-1209.

Dynamic replacements are currently written in extensions as

The runtime implementation allows an implementation in the future where
dynamic replacements are gather in a scope and can be dynamically
enabled and disabled.

For example:

dynamic_extension_scope CollectionOfReplacements {
  extension ExtentedType {
    func replacedFun() {}
  }

  extension ExtentedType2 {
    func replacedFun() {}
  }
}

object, because it (no longer?) uses any type lowering operations.

a8b1917512 [all-+0] Add a new convention for setters: DefaultSetterConventions.
In a situation where normal arguments are +0, we want setters to still take
normal parameters at +1 since in most cases setters will be taking a parameter
that is being forwarded into to be store into a field.

Since this doesn't actually change the current ParameterConvention for setter
normal arguments, this is NFC.

ce2a434587 SILGen: Fix bug with vtable entries for allocating initializers
Some changes I was working on uncovered a latent bug where we would
emit a class_method instruction to call an allocating initializer
that did not have a vtable entry.

Previously this wasn't caught because the only example of this in
our test suite was in test/SILGen/objc_bridging_any.swift, which
did not test with IRGen; if it did, an IRGen crash would have been
observed.

Factor out some code duplication to prevent this from happening
again, and add a SILGen test that we emit a vtable entry in this
case, and that the test case passes IRGen also.
