 If you would like to get the MIR:
 
-- for a function - you can use the `optimized_mir(def_id)` query;
-- for a promoted - you can use the `promoted_mir(def_id)` query.
+- for a function - you can use the `optimized_mir` query (typically used by codegen) or the `mir_for_ctfe` query (typically used by compile time function evaluation, i.e., *CTFE*);

 These will give you back the final, optimized MIR. For foreign def-ids, we simply read the MIR
 from the other crate's metadata. But for local def-ids, the query will
