AST: Slightly change meaning of NominalTypeDecl::getDeclaredType()
Consider this code:
struct A<T> {
struct B {}
struct C<U> {}
}
Previously:
- getDeclaredType() of 'A.B' would give 'A<T>.B'
- getDeclaredTypeInContext() of 'A.B' would give 'A<T>.B'
- getDeclaredType() of 'A.C' would give 'A<T>.C'
- getDeclaredTypeInContext() of 'A.C' would give 'A<T>.C<U>'
This was causing problems for nested generics. Now, with this change,
- getDeclaredType() of 'A.B' gives 'A.B' (*)
- getDeclaredTypeInContext() of 'A.B' gives 'A<T>.B'
- getDeclaredType() of 'A.C' gives 'A.C' (*)
- getDeclaredTypeInContext() of 'A.C' gives 'A<T>.C<U>'
(Differences marked with (*)).
Also, this change makes these accessors fully lazy. Previously,
only getDeclaredTypeInContext() and getDeclaredIterfaceType()
were lazy, whereas getDeclaredType() was built from validateDecl().
Fix a few spots where the return value wasn't being checked
properly.
These functions return ErrorType if a circularity was detected via
the generic parameter list, or if the extension did not resolve.
They return Type() if the extension cannot be resolved *yet*.
This is pretty subtle, and I'll need to do another pass over
callers of these functions at some point. Many of them should be
moved over to use getSelfInContext(), getSelfOfContext() and
getSelfInterfaceType() instead.
Finally, this patch consolidates logic for diagnosting invalid
nesting of types.
The parser had some code for protocols in bad places and bad things
inside protocols, and Sema had several different bail-outs for
bad things in protocols, nested generic types, and stuff nested
inside protocol extensions.
Combine all of these into a single set of checks in Sema. Note
that we no longer give up early if we find invalid nesting.
Leaving decls unvalidated and un-type-checked only leads to
further problems. Now that all the preliminary crap has been
fixed, we can go ahead and start validating these funny nested
decls, actually fixing some crashers in the process.

Sema: Clean up some code duplication when validating generic type signatures
Every call to validateGenericTypeSignature() had the same
boilerplate following; move the common logic into that
function.
As one might expect, each callsite had slight variants on
the same underlying logic -- this makes them consistent.
Also, this slightly widens the scope during which
GenericTypeDecl::isValidatingGenericSignature() returns
true.
Interesting, that change introduces a diagnostic in an
existing testcase where previously there was none:
protocol P {
associatedtype T
}
struct S<A: P where A.T == S<A>> {}
While it looks like this generic signature was built
correctly, in fact I think we weren't computing
conformances for the substitution of 'A' in 'S<A>'.
After trying small variations on the above testcase,
I quickly ran into SILGen crashes, which the diagnostic
now prevents. A few interesting cases still crash.
See test/decl/protocol/req/recursion.swift for the
gory details.

Sema: Use FoldingSetNode for ProtocolType
There was a weirdness with ProtocolType::get() that was causing me grief while trying to refactor getDeclaredType() and related code in another patch. Instead of caching the result like we do elsewhere, this would directly store the new type into the ProtocolDecl. This is smelly, so let's not do that. |

Sema: Improve a circularity-breaking hack
The old check was problematic because it would sometimes return ErrorType from accessing the generic parameters of a type that was in the process of having its generic signature validated. Instead fix the root cause of the circularity, which was recursion through resolveType() when resolving a type's inheritance clause. To fix it, let's just not walk adopted protocols when looking up the superclass of a class. Inheriting from an associated type does not seem very useful, and will probably be hard to get right in the general case. I wasn't able to reduce a useful test case, but this patch prevents compiler_crashers regressions with some other changes I'm working on. |

Sema: Better support for nested generic functions
There was a weird corner case with nested generic functions that would fail in the SIL verifier with some nonsense about archetypes out of context. Fix this the "right" way, by re-working Sema function declaration validation to assign generic signatures in a more principled way. Previously, nested functions did not get an interface type unless they themselves had generic parameters. This was inconsistent with methods nested inside generic types, which did get an interface type even if they themselves did not have a generic parameter list. There's some spill-over in SILGen from this change. Mostly it makes things more consistent and fixes some corner cases. |

AST: When performing qualified lookup of a member type, filter out non-types earlier
With the previous resolveTypeInContext() patch, a few compiler
crashers regressed with this problem, presumably because we were now
performing lookups in more contexts than before.
This is a class of problems where we would attempt a recursive
validation:
1) Generic signature validation begins for type T
2) Name lookup in type context finds a non-type declaration D nested in T
3) Generic signature validation begins for D
4) The outer generic context of D is T, but T doesn't have a generic
signature yet
The right way to break such cycles is to implement the iterative
decl checker design. However when the recursion is via name lookup,
we can try to avoid the problem in the first place by not validating
non-type declarations if the client requested a type-only lookup.
Note that there is a small semantic change here, where programs that
were previously rejected as invalid because of name clashes are
now valid. It is arguable if we want to allow stuff like this or not:
class A {
func A(a: A) {}
}
or
class Case {}
enum Foo {
case Case(Case)
}
However at the very least, the new behavior is better because it
gives us an opportunity to add a diagnostic in the right place
later. The old diagnostics were not very good, for example the
second example just yields "use of undeclared type 'Case'".
In other examples, the undeclared type diagnostic would come up
multiple times, or we would generate a cryptic "type 'A' used within
its own definition".
As far as I understand, this should not change behavior of any existing
valid code.

Sema: Fixes for protocol typealiases
This is a big refactoring of resolveTypeInContext() which makes
the function clearer to understand by merging various special
cases and generalizing the logic for walking parent and superclass
contexts to cover more cases.
This improves typealiases in protocols a bit:
1) Previously a typealias in a protocol either had to be concrete,
or consist of a single path of member types from Self, eg
Self.A.B. Lift this restriction, so we can now write things like
protocol Fireworks {
associatedtype Exploding
typealias Exploder = Exploding -> [Exploding]
}
2) Protocol typealiases can now be accessed via qualified lookup
on concrete types. Getting this working for unqualified lookup
requires further refactorings which will be in a subsequent
patch.

Disable typealiases in protocols and add frontend flag to re-enable.
Goes back to Swift 2.2 behavior of treating the 'typealias' keyword inside a protocol as a deprecated form of an associatedtype. To get the newer (but still partly buggy) behavior of treating it as an actual typealias, add "-Xfrontend -enable-protocol-typealiases" to the compile invocation. 'decl/typealias/typealias.swift' now uses this flag to continue testing the enabled behavior. |
