[SUA][IRGen] Add stub for swift_coroFrameAlloc that weakly links against the runtime function

Open t-rasmud opened this issue 1 year ago • 13 comments

This PR modifies IRGen to emit a stub function __swift_coroFrameAllocStub instead of the newly introduced swift-rt function swift_coroFrameAlloc. The stub checks whether the runtime has the symbol swift_coroFrameAlloc and dispatches to it if it exists, uses malloc otherwise. This ensures the ability to back deploy the feature to older OS targets.

You can restrict a test to run only on say macOS and iOS by adding the following line to the test:

// REQUIRES: OS=macosx || OS=iOS
