Struct Reach 

pub struct Reach { /* private fields */ }

What carries the address of each of a function’s locals, or None for one whose address gets away somewhere this pass cannot follow.

Worked out before allocation, because it is a question about values and a value is written once only until the allocator’s rewrite has been through. Read after it, because that is when the liveness these names are looked up in exists.
