So, I was looking up everywhere and could not find any mitigation for Spectre attack by the vim interpreter! I don't know if my question is correct or how feasible it is, but do you recall if there is any mitigation for different variants of Spectre attacks Specter v1 (Spectre-PHT), v2 (Spectre-BTB), v4 (Spectre-STL) and v5 (Spectre-RSB) at the interpreter level for vim?

Since Spectre is all about speculative execution and not the actual translation (interpretation) steps I thought it might be dangerous that there is not any mitigation for it by the interpreter, I might be way too wrong tho.

I just felt, since there's no mitigation, it might be a good idea to send a text and let you guys know about it. And please correct me if there are mitigations for spectre in vim interpreter.
