If the Clang declrations are *types*, canonical declaration in Swift is
imported for newest version of Swift. In interface generation, if the
declaration is versioned and it's imported as a member in either or both
version of Swift, we have to take compatibility typealias into account.
* Fixed 'ClangModuleUnit::getTopLevelDecls' to take isCompatibilityAlias() into account
* Fixed bugs in ClangImporter where member-to-member versioned types aren't properly imported.
* Fixed 'SwiftDeclConverter::importFullName' to check equality of getEffectiveContext()
* Fixed 'importer::addEntryToLookupTable' to check equality of getEffectiveContext()
(moved 'ClangImporter::Implementation::forEachDistinctName' to 'NameImporter')
Right now 'fileprivate' is parsed as an alias for 'private' (or
perhaps vice versa, since the semantics of 'private' haven't changed
yet). This allows us to migrate code to 'fileprivate' without waiting
for the full implementation.
Clang and Swift decls likely have many-to-one mappings; for instance,
a RecordDecl and a TypedefDecl in Clang are both imported as the same Swift
NominalTypeDecl. This commit reduces duplication when we print Clang decls in
Swift. rdar://23275959
At some point I want to propose a revised model for exports, but for now
just mark that support for '@exported' is still experimental and subject
to change. (Thanks, Max.)
The code goes into its own sub-tree under 'tools' but tests go under 'test',
so that running 'check-swift' will also run all the SourceKit tests.
SourceKit is disabled on non-darwin platforms.
