Null Values

val null : (Lang.F.term -> Lang.F.pred) Context.value

test for null pointer value

val is_null : Ctypes.c_object -> Lang.F.term -> Lang.F.pred

Start of Arrays

val startof : shift:('a -> Ctypes.c_object -> Lang.F.term -> 'a) -> 'a -> Frama_c_kernel.Cil_types.typ -> 'a

Typing and Sub-Typing for C and ACSL Types

val is_object : Ctypes.c_object -> 'a Sigs.value -> Lang.F.pred

val has_ctype : Frama_c_kernel.Cil_types.typ -> Lang.F.term -> Lang.F.pred

val cdomain : Ctypes.c_object -> (Lang.F.term -> Lang.F.pred) option

val ldomain : Frama_c_kernel.Cil_types.logic_type -> (Lang.F.term -> Lang.F.pred) option

Volatile Access

val volatile : ?warn:string -> unit -> bool

Check if a volatile access must be properly modelled or ignored. In case the volatile attribute comes to be ignored, the provided warning is emitted, if any.

ACSL Equality

type matrixinfo = Ctypes.c_object * int option list

val equal_object : Ctypes.c_object -> Lang.F.term -> Lang.F.term -> Lang.F.pred
