In addition to capturing more detailed preprocessor info, the
DetailedPreprocessorRecord option sets the clang module format to 'raw'
rather than the default 'object'. Sourcekitd doesn't link the code
generation libs, which it looks like the default 'object' format requires,
so it sets this option to true. The subinvocation generated when loading a
module from a .swiftinterface file still used the default prior to this
change though, so it would end up crashing sourcekitd.
This change sets the DetailedProccessorRecord option if the DetailedRecord
option is set on the preprocessor options of parent context's clang module
loader. This fixes interface generation crashing for modules that only have
a .swiftinterface file.

* Add swift_evolve feature and disable several tests
This change adds a swift_evolve feature to our lit configuration and uses it to mark several tests as unsupported by swift_evolve.
One of these—test/api-digester/stability-stdlib-abi.swift—is actually pretty bad; we would really like to have it. But the digester has known issues exposed by swift-evolve.
* Remove order dependency in another test
* Tweaks from Jordan’s review
* Distinguish between tests which are intentionally unsupported and temporarily disabled.
* Add an explanation for one unsupproted test.
* Code nitpick.
@effects is too low a level, and not meant for general usage outside
the standard library. Therefore it deserves to be underscored like
other such attributes.
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')
These tests were relying on sourcekitd parsing as frontend instead of
using the driver. Update them now to avoid churn when we fix command
line argument parsing in sourcekit.
The changes from clang-importer-sdk to clang-importer-sdk-nosource -I %t
are because clang-importer-sdk implies using -enable-source-import.
Rather than hack them up to use -Xfrontend, it is cleaner to just stop
using source import at all for these tests. Incidentally, this improved
fidelity in a few places. When using the generated swift modules we
also need to pass a target triple to sourcekit, which exposed some tests
that had mac-specific data. This is a systemic issue for sourcekit
tests, but for now just make those few specific tests that we had
problems with run only on mac.
Rather than mangling the complete generic signature of a constrained
extension, only mangle the requirements not already satisfied by the
nominal type. For example, given:
extension Dictionary where Value: Equatable {
// OLD: _T0s10DictionaryV2t3s8HashableRzs9EquatableR_r0_lE3baryyF
// NEW: _T0s10DictionaryV2t3s9EquatableR_rlE3baryyF
public func bar() { }
}
In the existing mangling, we mangle the `Key: Hashable` requirement that’s
part of the generic signature. With this change, we only mangle the new
requirement (`Value: Equatable`).
This is a win for constrained extensions *except* in the case of a
constrained extension of a nominal type with a single, unconstrained
generic parameter:
extension Array where Element: Equatable {
// OLD: _T0Sa2t3s9EquatableRzlE3baryyF
// NEW would be: _T0Sa2t3s9EquatableRzrlE3baryyF
public func bar() { }
}
Check explicily for this shortcut mangling and fall back to the old
path, so this change is a strict improvement.
Use the "override" information in associated type declarations to provide
AST-level access to the associated type "anchor", i.e., the canonical
associated type that will be used in generic signatures, mangling,
etc.
In the Generic Signature Builder, only build potential archetypes for
associated types that are anchors, which reduces the number of
potential archetypes we build when type-checking the standard library
by 14% and type-checking time for the standard library by 16%.
There's a minor regression here in some generic signatures that were
accidentally getting (correct) same-type constraints. There were
existing bugs in this area already (Huon found some of them), while
will be addressed as a follow-up.
Fies SR-5726, where we were failing to type-check due to missed
associated type constraints.
The various _*Indexable protocols only exist to work around the lack of
recursive protocol constraints. Eliminate all of the *_Indexable protocols,
collapsing their requirements into the corresponding Collection protocol
(e.g., _MutableIndexable —> Collection).
This introduces a number of extraneous requirements into the various
Collection protocols to work around bugs in associated type
inference. Specifically, to work around the lack of "global" inference
of associated type witnesses. These hacks were implicitly present in
the *Indexable protocols; I've made marked them as ABI FIXMEs here so
we can remove them when associated type inference improves.
Fixes rdar://problem/21935030 and a number of ABI FIXMEs in the library.
This patch allows Parser to generate a refined token stream to satisfy tooling's need. For syntax coloring, token stream from lexer is insufficient because (1) we have contextual keywords like get and set; (2) we may allow keywords to be used as argument labels and names; and (3) we need to split tokens like "==<". In this patch, these refinements are directly fulfilled through parsing without additional heuristics. The refined token vector is optionally saved in SourceFile instance.
I noticed in a follow-up patch that if you just swiftc without passing Onone
these flags are not set and sometimes happen to default to right thing ... or
not; as can be seen by the test cases modified. For example, at Onone we are
supposed to include an extra swift module "SwiftOnoneSupport".
...which didn't do the right thing in the presence of ModuleMacro,
depending on the order the macros were referenced. Already covered by
test/ClangImporter/macros.swift, but it actually seems to improve the
behavior of some of the SourceKit tests as well.
Continuing rdar://problem/32199805, which is just "get macros working
with clang::ModuleMacro".
I failed to merge the upstream changes to swift-corelibs-foundation at the same
time as I merged that #9806, and it broke on linux. Going to get it right this
time.
