Looks like you will have to adjust some UI tests. The approach LGTM, but I'd also like to hear @oli-obk's opinion. |

I believe other changes caused the two failing UI tests to output a recursive requirement warning rather than a depth limit exceeded, so the tests don't need updating anymore. I did manage to get "most" of a bless run done. EDIT: found the change: #66294 |

Use recursion_limit for const eval stack limit cc rust-lang/miri#643 @orium @RalfJung I'm really not certain how exactly to handle this change, but it looks like it's that simple. Reuse `recursion_limit` ("The maximum recursion limit for potentially infinitely recursive operations such as auto-dereference and monomorphization") which is configurable by the user for the const evaluation stack frame limit. The other option is to make `const_eval_stack_frame_limit` configurable in the same way as `recursion_limit` (but I'm not sure how to do that and it'd be a bigger change). Fixes rust-lang/miri#643.
