This commit defines the ‘Any’ keyword, implements parsing for composing
types with an infix ‘&’, and provides a fixit to convert ‘protocol<>’
- Updated tests & stdlib for new composition syntax
- Provide errors when compositions used in inheritance.
Any is treated as a contextual keyword. The name ‘Any’
is used emit the empty composition type. We have to
stop user declaring top level types spelled ‘Any’ too.
This removes conformance of DarwinBool and ObjCBool to the Boolean protocol,
and makes the &&/||/! operators be concrete w.r.t. Bool instead of abstract
on Boolean.
This fixes some outstanding bugs w.r.t diagnostics, but exposes some cases
where an existing diagnostic is not great. I'll fix that in a later patch
(tracked by rdar://27391581).
This is part 1 of many to enable leaks tracking in the unit test suite.
To compile with leak tracking enabled run
swift/utils/build-script -- --swift-runtime-enable-leak-checker
If a child process crashes outside of a test context, the parent process
should signal test failure. This behavior is a sign of something bad
happening in the child (for example, memory corruption), and should not
go unnoticed.
Previously, the callback for objc_setUncaughtExceptionHandler
took a parameter of type 'AnyObject!', which was implicitly
unwrapped at all uses inside the closure. When that became
'AnyObject?', we started getting an extra layer of Optional in
the printed output.
This reverts the tests to their pre-4d540c2a state.
This is a squash of the following commits:
* [SE-0054] Import function pointer arg, return types, typedefs as optional
IUOs are only allowed on function decl arguments and return types, so
don't import typedefs or function pointer args or return types as IUO.
* [SE-0054] Only allow IUOs in function arg and result type.
When validating a TypeRepr, raise a diagnostic if an IUO is found
anywhere other thn the top level or as a function parameter or return
tpye.
* [SE-0054] Disable inference of IUOs by default
When considering a constraint of the form '$T1 is convertible to T!',
generate potential bindings 'T' and 'T?' for $T1, but not 'T!'. This
prevents variables without explicit type information from ending up with
IUO type. It also prevents implicit instantiation of functions and types
with IUO type arguments.
* [SE-0054] Remove the -disable-infer-iuos flag.
* Add nonnull annotations to ObjectiveCTests.h in benchmark suite.
