This language makes it easier to describe various calling conventions using high-level combinators, built on top of the lower level primitives of the Arg language.
In Arg.Language we describe calling conventions declaratively using a list of commands, where each command is a guarded statement, i.e., a pair of a predicate and the statement. The statement is using the [Arg] operators to describe argument passing routine, and the predicate checks if this is applicable to the given arguement. Various combinators combine commands and predicates, into a final statement that fully describes the argument passing procedure for the given subroutine.
