The changes to the decl/ext/generic test strip out testing of
extensions of nested generics, a feature whose syntax will change and
is fairly broken already.
Swift SVN r21750
when type checking a reference to an optional requirement (producing
a dynamic_member_ref), downcast the receiver to the protocol in question
instead of to AnyObject. At SILGen time, we do an unchecked_ref_cast anyway,
and this is a more general solution to the problem it is trying to solve.
Swift SVN r21515
Previously, we were just storing setter accessibility via the accessibility
level on the setter function. However, some Stored properties never actually
have a setter synthesized, which led to the compiler dropping the setter
accessibility at serialization time. Rather than try to hack up something
clever, just store the setter accessibility explicitly in every
AbstractStorageDecl. (We still only serialize it for VarDecls, because
settable SubscriptDecls always have setter functions.)

attribute. As part of this, introduce a new "NotSerialized" flag in Attr.def.
This eliminates a bunch of special case code in the parser and elsewhere for handling
this modifier.
Swift SVN r19997
- Change the parser to accept "objc" without an @ sign as a contextual
keyword, including the dance to handle the general parenthesized case.
- Update all comments to refer to "objc" instead of "@objc".
- Update all diagnostics accordingly.
- Update all tests that fail due to the diagnostics change.
- Switch the stdlib to use the new syntax.
This does not switch all tests to use the new syntax, nor does it warn about
the old syntax yet. That will be forthcoming. Also, this needs a bit of
refactoring, which will be coming up.
Swift SVN r19555
We no longer need this language feature. The Sema support is still skeletally kept in place because removing it seems to totally break pointer conversions; I need to work with Joe and Doug to figure out why that's the case.
Swift SVN r19289
No validation is done yet on whether the user-specified access control makes
sense in context, but all ValueDecls should at least /have/ accessibility now.
/Still/ no tests yet. They will be much easier to write once we're actually
enforcing access control and/or printing access control.
Swift SVN r19143
Add primitive type-checker rules for pointer arguments. An UnsafePointer argument accepts:
- an UnsafePointer value of matching element type, or of any type if the argument is UnsafePointer<Void>,
- an inout parameter of matching element type, or of any type if the argument is UnsafePointer<Void>, or
- an inout Array parameter of matching element type, or of any type if the argument is UnsafePointer<Void>.
A ConstUnsafePointer argument accepts:
- an UnsafePointer, ConstUnsafePointer, or AutoreleasingUnsafePointer value of matching element type, or of any type if the argument is ConstUnsafePointer<Void>,
- an inout parameter of matching element type, or of any type if the argument is ConstUnsafePointer<Void>, or
- an inout or non-inout Array parameter of matching element type, or of any type if the argument is ConstUnsafePointer<Void>.
An AutoreleasingUnsafePointer argument accepts:
- an AutoreleasingUnsafePointer value of matching element type, or
- an inout parameter of matching element type.
This disrupts some error messages in unrelated tests, which is tracked by <rdar://problem/17380520>.
Swift SVN r19008
This means that we'll get deferred checking of array and dictionary
downcasts when writing "arr as Derived[]",
"(dict as? Dictionary<DerivedKey, DerivedValue>)!", etc, when the
collection can do so.
This is both a general optimization and also staging for
<rdar://problem/17319154>.
Swift SVN r18975
Semantically, these expressions handle the same thing: an upcast of a
collection when the underlying element types of the source are
subtypes of or can be bridged to subtypes of the destination. This
reduces some branching in the type checker and eliminates duplication
in SILGen.
Swift SVN r18865
This was triggered when verifying a decl that was deserialized from a
swiftmodule, but only because the decl was the Swift version of a decl
available in a generated Objective-C header read by the Clang importer.
No test case because it would be a negative test based on the compiler's
current internal logic.
Swift SVN r18441
Array downcast is an explicit cast written "x as U[]", not an implicit
conversion, so make it a subclass of ExplicitCastExpr. The only
effective change here is that we retain the location of the "as" and
the type as written in the AST. No semantic change.
Swift SVN r18391
- Continue adding support for checked downcasts of array types (rdar://problem/16535104)
- Fix non-bridged array conversions post-r17868
- Fix rdar://problem/16773693
- Add tests for NSArray coercions to and from Array<T>
Swift SVN r17957
We were accidentally forcing all members of a class to be instantiated in two places:
- by trying to look up an existing destructor decl in the class, and
- by adding the implicit destructor to the class, because addMember needlessly called loadAllMembers.
Fix the former problem by adding a 'has destructor' bit to ClassDecl so we can track whether the implicit destructor needs to be added without querying its members. Fix the latter by making IterableDeclContext::addMember not call loadAllMembers, and making loadAllMembers not barf when it sees existing members in the context.
Together with Jordan and JoeP's changes, this makes many interpreter tests now compile 3-20x faster.
Swift SVN r17562
I got a little ahead of myself on this one, so without the remaining work for rdar://problem/16540403 it wasn't quite correct. For now just descend into the sub expression.
Swift SVN r16859
them with uses of TypeExpr instead. The remaining uses of
MetaTypeExpr (which will be renamed soon) are places where we
are applying the ".dynamicType" virtual property to an expression.
Unadorned uses of types in code, e.g. the Int in "Int.self" are
now represented with TypeExpr.
One unfortunate travesty that doing this work revealed is that we
are extremely sloppy and terrible about maintaining location information
in implicitly generated decls, and our invariants vary quite a bit. This
is really horrible, but I'm not sure whether I'll go fix the hacks or not.
This patch perpetuates the existing crimes, but makes them more visible.
