Callstacks related types and functions




Callstacks related types and functions


type call_site = Cil_types.kernel_function * Cil_types.kinstr 
A call_stack is a list, telling which function was called at which site. The head of the list tells about the latest call.
type callstack = call_site list 
val clear_call_stack : unit -> unit
Functions dealing with call stacks.
val pop_call_stack : unit -> unit
val push_call_stack : Cil_types.kernel_function -> Cil_types.kinstr -> unit
val current_kf : unit -> Cil_types.kernel_function
The current function is the one on top of the call stack.
val call_stack : unit -> callstack
val pp_callstack : Format.formatter -> unit
Prints the current callstack.

val emitter : Emitter.t

val pretty_current_cfunction_name : Format.formatter -> unit
val warning_once_current : ('a, Format.formatter, unit) Pervasives.format -> 'a
val alarm_report : ?level:int -> 'a Log.pretty_printer
Emit an alarm, either as warning or as a result, according to option AlarmsWarnings.
module DegenerationPoints: State_builder.Hashtbl  with type key = stmt and type data = bool
val create_new_var : string -> Cil_types.typ -> Cil_types.varinfo
Create and register a new variable inside Frama-C. The variable has its vlogic field set, meaning it is not a source variable. The freshness of the name must be ensured by the user.
val is_const_write_invalid : Cil_types.typ -> bool
Detect that the type is const, and that option -global-const is set. In this case, we forbid writing in a l-value that has this type.
val float_kind : Cil_types.fkind -> Fval.float_kind
Classify a Cil_types.fkind as either a 32 or 64 floating-point type. Emit a warning when the argument is long double, and long double is not equal to double
val postconditions_mention_result : Cil_types.funspec -> bool
Does the post-conditions of this specification mention \result?
val conv_comp : Cil_types.binop -> Abstract_interp.Comp.t
val conv_relation : Cil_types.relation -> Abstract_interp.Comp.t
val zero : Cil_types.exp -> Cil_types.exp
Return a zero constant compatible with the type of the argument
val is_value_zero : Cil_types.exp -> bool
Return true iff the argument has been created by Value_util.zero
val dump_garbled_mix : unit -> unit
print information on the garbled mix created during evaluation

Dependences of expressions and lvalues.
val zone_of_expr : (Cil_types.lval -> Precise_locs.precise_location) ->
Cil_types.exp -> Locations.Zone.t
Given a function computing the location of lvalues, computes the memory zone on which the value of an expression depends.
val indirect_zone_of_lval : (Cil_types.lval -> Precise_locs.precise_location) ->
Cil_types.lval -> Locations.Zone.t
Given a function computing the location of lvalues, computes the memory zone on which the offset and the pointer expression (if any) of an lvalue depend.
