Nate Chandler	06921cfe84	[SIL] Hollow out Builtin.copy, deprecate _copy. ... The copy operator has been implemented and doesn't use it. Remove `Builtin.copy` and `_copy` as much as currently possible. Source compatibility requires that `_copy` remain in the stdlib. It is deprecated here and just uses the copy operator. Handling old swiftinterfaces requires that `Builtin.copy` be defined. Redefine it here as a passthrough--SILGen machinery will produce the necessary copy_addr. rdar://127502242	2024-05-03 15:56:25 -07:00
Kavon Farvardin	2c7d9a5047	update tests given move-only types are enabled ... the main things still left behind the experimental flag(s) are - move-only classes (guarded by MoveOnlyClasses feature) - noimplicitcopy - the _borrow operator	2023-03-14 18:35:13 -07:00
Michael Gottesman	f9122a79b7	[moveOnly] Implement a new _copy function that performs an explicit copy value. ... The key thing is that the move checker will not consider the explicit copy value to be a copy_value that can be rewritten, ensuring that any uses of the result of the explicit copy_value (consuming or other wise) are not checked. Similar to the _move operator I recently introduced, this is a transparent function so we can perform one level of specialization and thus at least be generic over all concrete types.	2021-10-29 15:37:46 -07:00
