- stop storing the parent task in the TaskGroup at the .swift level - make sure that swift_taskGroup_isCancelled is implied by the parent task being cancelled - make the TaskGroup structs frozen - make the withTaskGroup functions inlinable - remove swift_taskGroup_create - teach IRGen to allocate memory for the task group - don't deallocate the task group in swift_taskGroup_destroy To achieve the allocation change, introduce paired create/destroy builtins. Furthermore, remove the _swiftRetain and _swiftRelease functions and several calls to them. Replace them with uses of the appropriate builtins. I should probably change the builtins to return retained, since they're working with a managed type, but I'll do that in a separate commit.

// LANGUAGE_FEATURE(FeatureName, SENumber, Description, Option)
|
|
//
|
|
// The LANGUAGE_FEATURE macro describes each named feature that is
|
|
// introduced in Swift. It allows Swift code to check for a particular
|
|
// feature with "#if $FeatureName" in source code.
|
|
//
|
|
// FeatureName: The name given to this feature to be used in source code,
|
|
// e.g., AsyncAwait.
|
|
// SENumber: The number assigned to this feature in the Swift Evolution
|
|
// process, or 0 if there isn't one.
|
|
// Description: A string literal describing the feature.
|
|
// Option: either a reference to a language option in the form
|
|
// "langOpts.<option name>" or "true" to indicate that it's always
|
|
// enabled.
