This paper presents an approach to deriving concurrency oracles for processor instructions whose behaviour is formally specified using a state transformer semantics. The presented approach does not require any modification of the existing semantics, nor does it rely on writing a parser for the language in which the semantics is described, thus justifying the “for free” part of the title. The main tool in our arsenal is ad-hoc polymorphism: the presented approach is only applicable when the semantics of processor instructions is expressed using state transformation functions that can be reinterpreted in different contexts. As we show in the paper, such semantics can be interpreted not only for instruction simulation or verification, but also for extracting the information about instruction dependencies, thus allowing us to identify concurrency as well as various types of conflicts between instructions or blocks of instructions.
