John McCall	60807a76a4	Merge pull request #71433 from rjmccall/isolated-any-typechecking ... Experimental type-checking support for `@isolated(any)` function types.	2024-02-07 14:07:53 -05:00
Kavon Farvardin	1c2dbf4498	NCGenerics: avoid synthesizing Equatable, etc. ... While certain kinds of enums synthesize Equatable, Hashable, and RawRepresentable conformances, we can't yet permit noncopyable types to synthesize those until we upgrade those protocols themselves to not require `Copyable` conformers. For example, Equatable needs to be changed in the stdlib to be `protocol Equatable: ~Copyable`, etc. I'm deferring upgrade work until a bit later.	2024-02-07 11:05:08 -08:00
Hamish Knight	d73e394ea7	Allow implicit last expression results for if/switch expressions ... Allow implicitly treating the last expression of the branch as the result, behind the experimental feature `ImplicitLastExprResults`.	2024-02-07 18:14:22 +00:00
Joe Groff	e46168c626	SILGen: Improve handling of copyable subpatterns in borrowing switches. ... A `let` binding of a copyable subpattern can create an independent variable which should be copyable and consumable without affecting a borrowed move-only base. In the same way that `borrowing` parameters are no-implicit-copy, though, explicitly `_borrowing` subpatterns of copyable type should be no-implicit-copy as well.	2024-02-07 07:21:11 -08:00
Anton Korobeynikov	aa5b505014	Allow normal function results of @yield_once coroutines (#69843) ... This adds SIL-level support and LLVM codegen for normal results of a coroutine. The main user of this will be autodiff as VJP of a coroutine must be a coroutine itself (in order to produce the yielded result) and return a pullback closure as a normal result. For now only direct results are supported, but this seems to be enough for autodiff purposes.	2024-02-06 22:13:15 -08:00
John McCall	2f8a33cf0a	Experimental type-checking support for @isolated(any) function types.	2024-02-06 22:54:27 -05:00
Kavon Farvardin	70266b589a	NCGenerics: avoid UGT's in queries ... An unbound generic type is not something that should end up in `isNoncopyable` or `isEscapable` queries because there are no conformances for such a type; it's unbound! fixes test/Constraints/closures.swift	2024-02-06 08:15:26 -08:00
Kavon Farvardin	f0b4f4a865	NCGenerics: omit inverses on invertible protocols ... The interface files were still printing inverses on the invertible protocols, when that's not required. Doing so yielded warnings during the build because `~Escapable` isn't yet ready for appearing in the stdlib.	2024-02-06 08:15:26 -08:00

Nate Chandler	336afca477	[SILOpt] Removed unreachable bailouts. ... Now that supportsMoveOnlyTypes is always true, these bailouts can't be reached. Delete the bailouts and the predicate.	2024-02-05 17:40:17 -08:00
Nate Chandler	af1da401d9	[Frontend] Removed dead case. ... It is no longer possible to have no lexical markers. Remove the corresponding case.	2024-02-05 17:39:01 -08:00
Artem Chikin	0046165dad	[DependencyScanning] Isolate 'DependencyScanningTool' reset operations ... Guard 'resetCache' and 'resetDiagnostics' as critical sections using 'DependencyScanningToolStateLock'. Otherwise there's a chance that one thread in the scanner is doing a reset on the diagnostic consumer, while some other thread is adding this diagnostic consumer to another scan instance which may also be populating said consumer at the time. Similarly, for resetting 'ScanningService' though it is much more unlikely to be reset while in-use by other scanning actions.	2024-02-05 16:00:39 -08:00

Hamish Knight	16cfca4186	[ASTWalker] NFC: Rename SkipChildren -> SkipNode ... This better describes what the action currently does, and allows us to re-introduce `SkipChildren` with the correct behavior.	2024-02-05 15:27:25 +00:00
Hamish Knight	aa51e04d28	Remove PreWalkAction/PostWalkAction constructors ... Help avoid using e.g `PreWalkAction::SkipChildren` directly, and reduce duplication of walk actions to take.	2024-02-05 15:27:25 +00:00

Kavon Farvardin	a816489024	RequirementLowering: remove assert ... Finding a structural requirement that is not involving an invertible protocol is not suspicious at all.	2024-02-04 19:57:29 -08:00

John McCall	dd90ae7416	Rename SIL's @isolated attribute to @sil_isolated. ... We want to use @isolated in ordinary Swift, and while we could probably make it coexist with this SIL use, doing so would be really inconvenient.	2024-02-03 01:51:36 -05:00

Kavon Farvardin	3908c8182d	NCGenerics: sometimes synth. Copyable/Escapable ... When the Swift module is not available, we'll synthesize the Copyable/Escapable decls into the Builtin module. In the future, it might be nice to just do this always, and define typealiases for those types in the stdlib to refer to the ones in the builtin module.	2024-02-02 18:47:03 -08:00
