This doesn't do anything yet, but will be used to record which decls
conform to these protocols when serializing a module.
This introduces a new metaprogramming file, KnownProtocols.def.
Swift SVN r7263
Turn NominalType::FieldRange into a more general template that can filter by any member decl type and predicate. Use an instance of it in UnionDecl::getAllElements to iterate through all its contained UnionElementDecls.
Swift SVN r7218
Teach the ArchetypeBuilder how to use callbacks to get at the
protocols from which a protocol inherits and to which an associated
type conforms, so that we can use the type checker's lazy resolution
here.
Swift SVN r7107
As discussed, this is an interim syntax for re-exports:
import [exported] Foundation
In the long run, we're probably going to use the same syntax as access
control for this, but that hasn't been designed yet.
Swift SVN r7050
We never really discussed this and it doesn't really buy us much. If we
want to have a compact way to import many things, it may not even end
up looking like this.
Swift SVN r7015
Again, the import kind rules are:
- 'import KIND' can import any decl whose introducer is KIND.
- 'import typealias' can also import a struct, class, or union.
- Conversely, 'import KIND' can import a typealias for a decl whose
introducer is KIND.
- Only functions can be overloaded; anything else counts as an ambiguous
import and is an error.
- If an import statement only imports a single decl, but the user got the
kind wrong, we can issue a fix-it for the kind.
We don't have source locations or synthetic source for declarations yet,
so there are no notes about what's /causing/ the ambiguities. Tracked by
<rdar://problem/14650883>
Swift SVN r6917
capture analysis is gone. This functionality is subsumed by SIL passes,
which turn boxes into stack allocations.
One minor detail of this is that dealloc_ref isn't implemented yet in IRGen
(rdar://14648382) and SILGen produces it for destructors (e.g. see
test/SILGen/lifetime.swift). To unblock progress, I just removed the
llvm_unreachable in IRGen.
Swift SVN r6890
Build a switch_union instruction over all the matched union elements, and check for exhaustiveness to see if we need to emit a default branch either for subsequent matches or to fall off the end and emit unreachable if we run out of cases.
Swift SVN r6870
This makes it very clean to reason about which part should be used
to find a module to load, and which part should be used to filter
lookup within that module.
This breaks the old "import swift.print" syntax in favor of the new
"import func swift.print", but the new syntax is currently ignored.
Swift SVN r6849
Also, update LangRef.
Note that an explicit "import module" has been left out for now, since
it's not strictly necessary and "module" isn't a keyword yet.
Swift SVN r6786
We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!
Swift SVN r6783
Now that we have true serialized modules, the standard library can import
the Builtin module without any special direction (beyond -parse-stdlib),
and anyone can include those modules without special direction.
Swift SVN r6752
Standardize on the more-common "superclass" and "subclass" terminology
throughout the compiler, rather than the odd mix of base/derived and
super/sub.
Also, have ClassDecl only store the Type of the superclass. Location
information will be part of the inheritance clause for parsed classes.
Swift SVN r6687
The 'inherited' type list of a declaration represents the parsed for
of the inheritance clause, which is now not serialized. The semantic
informance exists in the superclass (when present) and list of
protocols. Future refactoring of the 'inherited' list will make this
more clear.
Swift SVN r6686
-Refactor Parser to stop creating types
-Refactor TypeChecker to create types by resolving TypeReprs.
-Remove "validation" bit from the type system.
We don't need to "validate" every type that gets created but there's still a validation bit in TypeLoc,
necessary because of generic substitutions.
Swift SVN r6326
Teach TuplePatternElt to keep track of the kind of the default
argument: none, normal (provided by calling into the appropriate
callee generator), __FILE__, __LINE__, or __COLUMN__. For the latter
three cases, the type checker forms the appropriate argument as part
of the call.
The actual default argument expression will only be held in the tuple
pattern element when we've parsed it; it won't be serialized or
deserialized, because only the defining module cares. This is a step
toward eliminate the initialization expression from tuple types.
The extension to TupleShuffleExpr is a hack, which will also be
replicated in ScalarToTupleExpr, until we finally rework the
representation of TupleShuffleExpr (<rdar://problem/12340004>).
Swift SVN r6299
Give oneof bodies syntax consistent with other NominalTypes. Give oneof elements first-class declaration syntax using the 'case' introducer, as suggested by Jordan. Oneofs can contain 'case' decls, functions, properties, and constructors, but not physical ivars. Non-oneof scopes cannot contain 'case' decls. Add some QoI to the oneof 'case' parser to also parse and complain about things that resemble switch 'case' labels inside decl contexts.
Swift SVN r6211
Previously, this set of protocols was computed lazily, which fails
catastrophically if getProtocols() was invoked before validation of
the types in a type/extension's "inherited" list.
Swift SVN r5924
This lookup routine takes the place of MemberLookup for AST-level
lookups, which don't consider semantics at all and won't be able to
(for example) perform additional type checking to resolve the
lookup. No functionality change.
Swift SVN r5882
The lookup table for a nominal type declaration provides efficient
(O(1)) access to all of the declarations with a given name in a
nominal type and its extensions. This is architecturally different
from Clang's handling of Objective-C classes and
categories/extensions, where each category/extension has its own
lookup table, and is meant to reduce the number of hash table lookups
required, especially once these hash tables are stored in the module.
The lookup table is built and updated lazily as extensions and members
are introduced, similarly to Clang's lookup tables. However, the
simpler name lookup rules in Swift (vs. C/C++/Objective-C) make this
approach actually semantically correct.
Swift SVN r5874
This causes the SourceLoader to recursively parse the imported module in standard
library mode, giving it access to the Builtin module.
This is all a terrible hack and should be ripped out with great victory someday, but
until we have binary modules that persist the build setting used to produce the
module, this is the best we can do.
Swift SVN r5847
Introduce Pattern subclasses for the 'is T', 'T(<pattern>)', and '<expr>' pattern syntaxes we'll be introducing for pattern-matching "switch" statements. Also add an 'UnresolvedCalLPattern' to act as an intermediate for name lookup to resolve to a nominal type, oneof element, or function call expression pattern. Since we'll need to be able to rewrite patterns like we do expressions, add setters to AST nodes that contain references to subpatterns. Implement some basic walking logic in places we search patterns for var decls, but punt on any more complex type-checking or SILGen derived from these nodes until we actually use them.
Swift SVN r5780
Sub-patterns are now considered part of the enclosing pattern, so if the
parent pattern pointer is const, the child pointer will be too.
I changed the minimal number of files to make this work, but future code
should use "const Pattern *" when intended, and "Pattern *" only if they
intend to modify the pattern.
Swift SVN r5743
Just refer to "class archetypes" and "class protocols". Change 'isClassBounded' methods to 'requiresClass', which is a character shorter.
Swift SVN r5674
When type-checking explicit protocol conformances for a type or extension, save the ProtocolConformance mappings from that declaration in the decl node. We'll need this in order to emit ObjC protocol conformances, which can't be emitted internally on-demand the way we currently emit Swift protocol witness tables. No functionality change.
Swift SVN r5632
Reject attempts by non-class types to conform to class-bound protocols, whether bound directly by a [class_protocol] attribute or indirectly by refining a class-bound protocol.
Swift SVN r5552
Creating forwarding substitutions is straightforward enough that we don't need to fudge them in the AST, so remove the forwarding substitutions from ConstructorDecl and construct them instead on the fly in SILGen. We're going to need to be able to forward archetypes in other places in SILGen, such as when emitting closures or curried thunks in generic contexts. No functionality change.
Swift SVN r5418
This replaces the obscure, inefficient lookup into extensions with
something more straightforward: walk all of the known extensions
(available as a simple list), then eliminate any declarations that
have been shadowed by other declarations. The shadowing rules still
need to consider the module re-export DAG, but we'll leave that for
later.
As part of this, keep track of the last time we loaded extensions for
a given nominal type. If the list of extensions is out-of-date with
respect to the global generation count (which tracks resolved module
imports), ask the modules to load any additional extensions. Only the
Clang module importer can currently load extensions in this manner.
