Pull request overview
This PR updates CoreCLR’s tiered compilation eligibility rules to allow runtime async “async version” methods to participate in tiering (and thus become candidates for tiered PGO), while continuing to exclude wrapper-thunk async methods that are not supported.
Changes:
- Relaxed the tiering exclusion for async thunk methods to allow those that
SupportsAsyncVersionCodegen(). - Updated the in-code comment describing async tiering behavior (though the wording could be made more precise; see review comments).

In theory why not, but there was a chance of some implementation detail to require adjustment. Nice that it “just works”. |
