Josh Bleecher Snyder e26499153e cmd/compile: use a map to track const switch cases ... This is simpler than the sorting technique. It also allows us to simplify or eliminate some of the sorting decisions. Most important, sorting will not work when case clauses represent ranges of integers: There is no correct sort order that allows overlap detection by comparing neighbors. Using a map allows of a cheap, simple approach to ranges, namely to insert every int in the map. The equivalent approach for sorting means juggling temporary Nodes for every int, which is a lot more expensive.
