What I've implemented here deviates from the current proposal text
in the following ways:
- I had to introduce a FunctionArrowPrecedence to capture the parsing
of -> in expression contexts.
- I found it convenient to continue to model the assignment property
explicitly.
- The comparison and casting operators have historically been
non-associative; I have chosen to preserve that, since I don't
think this proposal intended to change it.
- This uses the precedence group names and higherThan/lowerThan
as agreed in discussion.
* [Type System] Handle raw pointer conversion.
As proposed in SE-0107: UnsafeRawPointer.
https://github.com/apple/swift-evolution/blob/master/proposals/0107-unsaferawpointer.md#implicit-argument-conversion
UnsafeMutablePointer<T> -> UnsafeMutableRawPointer
UnsafeMutablePointer<T> -> UnsafeRawPointer
UnsafePointer<T> -> UnsafeRawPointer
UnsafeMutableRawPointer -> UnsafeRawPointer
inout:
&anyVar -> UnsafeMutableRawPointer
&anyVar -> UnsafeRawPointer
array -> UnsafeRawPointer
string -> UnsafeRawPointer
varArray -> UnsafeMutableRawPointer
* Rename expectEqual(_, _, sameValue:) to expectEqualTest to workaround a type system bug.
<rdar://26058520> Generic type constraints incorrectly applied to functions with the same name
This is exposed by additions to the type system for UnsafeRawPointer.
Warning: unit tests fail very confusingly without this fix.
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.
As proposed in SE-0107: UnsafeRawPointer:
Rename 'init(allocatingCapacity:)' to 'UnsafeMutablePointer.allocate(capacity:)'
Rename 'deallocateCapacity' to 'deallocate(capacity:)'
`allocate` should not be an initializer. It's primary function is to allocate
memory, not initialize a pointer.
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).
pthreads is not available on non-POSIX platforms (i.e. Windows). Restrict the
target platforms that we build SwiftPrivatePthreadExtras and things which depend
on it.
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
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
