Summary

Introduce a new command-line flag -swift-async-fp={auto|always|never}
that controls how code generation sets the Swift extended async frame
info bit. There are three possibilities:

  • auto: the default, which determines how to set the bit based on

deployment target, either statically or dynamically via
swift_async_extendedFramePointerFlags.

  • always: always set the bit statically, regardless of deployment

target.

  • never: never set the bit, regardless of deployment target.
