More unsubtyping for cont.bind - #8506
Merged
Merged
Conversation
We were missing a few type constraints for cont.bind. Add them, and also add more thorough tests for all the stack switching instructions, including the cases where the continuations are null. As a drive-by to get these tests working, fix the parsing of resume and resume_throw* to set the proper type arity when the input is null.
