  2. post : 'a;
}
Sourcetype 'a binder = {
  1. bind : 'b 'c. 'a -> ('b -> 'c) -> 'b -> 'c;
}
Sourcetype equation =
  1. | Set of Lang.F.term * Lang.F.term
    (*

Access conditions

Sourcetype 'a value =
  1. | Val of Lang.F.term

Reversing Models

It is sometimes possible to reverse memory models abstractions into ACSL left-values via the definitions below.

Sourcetype s_lval = s_host * s_offset list

Reversed ACSL left-value

Sourceand s_host =
  1. | Mvar of Frama_c_kernel.Cil_types.varinfo
    (*

    Variable

    *)
  2. | Mmem of Lang.F.term
    (*

    Pointed value

    *)
  3. | Mval of s_lval
    (*

    Pointed value of another abstract left-value

    *)
Sourceand s_offset =
  1. | Mfield of Frama_c_kernel.Cil_types.fieldinfo
  2. | Mindex of Lang.F.term
Sourcetype mval =
  1. | Maddr of s_lval
    (*

    The value is the address of an l-value in current memory

    *)
  2. | Mlval of s_lval
    (*

    The value is the value of an l-value in current memory

    *)
  3. | Minit of s_lval
    (*

    The value is the init state of an l-value in current memory

    *)
  4. | Mchunk of Sigma.Chunk.t
    (*

    The value is an abstract memory chunk (description)

    *)

Reversed abstract value

Sourcetype update =
  1. | Mstore of s_lval * Lang.F.term
    (*

    An update of the ACSL left-value with the given value

    *)

Reversed update
