Module Frama_c_kernel.Cil_builtins

Builtins management

module Frama_c_builtins : State_builder.Hashtbl with type key = string and type data = Cil_types.varinfo

This module associates the name of a built-in function that might be used during elaboration with the corresponding varinfo. This is done when parsing ${FRAMAC_SHARE}/libc/__fc_builtins.h, which is always performed before processing the actual list of files provided on the command line (see File.init_from_c_files). Actual list of such built-ins is managed in Cabs2cil.

val is_builtin : Cil_types.varinfo -> bool
  • returns

    true if the given variable refers to a Frama-C builtin.

  • since Fluorine-20130401
val is_unused_builtin : Cil_types.varinfo -> bool
  • returns

    true if the given variable refers to a Frama-C builtin that is not used in the current program. Plugins may (and in fact should) hide this builtin from their outputs

val is_special_builtin : string -> bool
  • returns

    true if the given name refers to a special built-in function. A special built-in function can have any number of arguments. It is up to the plug-ins to know what to do with it.

  • since Carbon-20101201
val add_special_builtin : string -> unit

register a new special built-in function

val add_special_builtin_family : (string -> bool) -> unit

register a new family of special built-in functions.

  • since Carbon-20101201
val init_builtins : unit -> unit

initialize the C built-ins. Should be called once per project, after the machine has been set.

module Builtin_functions : State_builder.Hashtbl with type key = string and type data = Cil_types.typ * Cil_types.typ list * bool

A list of the built-in functions for the current compiler (GCC or * MSVC, depending on !msvcMode). Maps the name to the * result and argument types, and whether it is vararg. * Initialized by Cil.initCIL. Do not add builtins directly, use * add_custom_builtin below for that. * * This map replaces gccBuiltins and msvcBuiltins in previous * versions of CIL.

type compiler =
  1. | GCC
  2. | MSVC
  3. | Not_MSVC
val string_of_compiler : compiler -> string
type builtin_template = {
  1. name : string;
  2. compiler : compiler option;
  3. rettype : string;
  4. args : string list;
  5. types : string list option;
  6. variadic : bool;
}
module Builtin_templates : State_builder.Hashtbl with type key = string and type data = builtin_template
val init_gcc_builtin_templates : unit -> unit
val add_custom_builtin : (unit -> string * Cil_types.typ * Cil_types.typ list * bool) -> unit

Register a new builtin. The function will be called after setting the machdep and initializing machine-dependent builtins. Hence, types such Cil.uint16_t might be used if needed.

  • since 23.0-Vanadium
val builtinLoc : Cil_types.location

This is used as the location of the prototypes of builtin functions.
