When we have looked into this, we rather quickly concluded that the expected fix-the-stack-and-branch approach was hopeless. Instead we will need to define a “tailcall” hardware operation that does all the internals like a call but reuses (and extends) the pre-existing frame in a very Mill-specific way. Details TBD.

Right, that why I was bringing it up. You need a dedicated tail-call instruction, otherwise compilers can’t implement it at all.
