Structs

LocationIndex
LocationTable

Maps between a MIR Location, which identifies a particular statement within a basic block, to a "rich location", which identifies at a finer granularity. In particular, we distinguish the start of a statement and the mid-point. The mid-point is the point just before the statement takes effect; in particular, for an assignment A = B, it is the point where B is about to be written into A. This mid-point is a kind of hack to work around our inability to track the position information at sufficient granularity through outlives relations; however, the rich location table serves another purpose: it compresses locations from multiple words into a single u32.
