2 (** This module defines the instrumentation of a [Clight] program. *)
4 (** [instrument prog cost_map] instruments the program [prog]. First a fresh
5 global variable --- the so-called cost variable --- is added to the program.
6 Then, each cost label in the program is replaced by an increment of the cost
7 variable, following the mapping [cost_map]. The function also returns the
8 name of the cost variable, the name of the cost increment function, and a
9 fresh uninitialized global (cost) variable associated to each extern
