Module Visitor

module Visitor: sig .. end

Frama-C visitors dealing with projects.

class type frama_c_visitor = object .. end

Class type for a Db-aware visitor.

class frama_c_inplace : frama_c_visitor

in-place visitor; always act in the current project.

class frama_c_copy : Project.t -> frama_c_visitor

Copying visitor.

class frama_c_refresh : Project.t -> frama_c_visitor

Similar to Visitor.frama_c_copy, but ids will be refreshed in the copy.

class generic_frama_c_visitor : Visitor_behavior.t -> frama_c_visitor

Generic class that abstracts over frama_c_inplace and frama_c_copy.

val visitFramacFileCopy : frama_c_visitor -> Cil_types.file -> Cil_types.file

Visit a file. This will re-cons all globals TWICE (so that it is tail-recursive). Use Cil.visitCilFileSameGlobals if your visitor will not change the list of globals.

val visitFramacFile : frama_c_visitor -> Cil_types.file -> unit

Same thing, but the result is ignored. The given visitor must thus be an inplace visitor. Nothing is done if the visitor is a copy visitor.

val visitFramacFileSameGlobals : frama_c_visitor -> Cil_types.file -> unit

A visitor for the whole file that does not change the globals (but maybe changes things inside the globals). Use this function instead of Visitor.visitFramacFile whenever appropriate because it is more efficient for long files.

val visitFramacFileFunctions : frama_c_visitor -> Cil_types.file -> unit

Visit all function definitions of a file. Use this function instead of Visitor.visitFramacFile or Visitor.visitFramacFileSameGlobals if your visitor only needs function bodies to avoid visiting other globals, including libc functions and their specifications.

val visitFramacGlobal : frama_c_visitor -> Cil_types.global -> Cil_types.global list

Visit a global.

Warning Do not call this function during another visit using the same visitor, as it is not reentrant: the inner visit will leave the visitor in an inconsistent state for the outer visit.

val visitFramacKf : frama_c_visitor -> Kernel_function.t -> Kernel_function.t

Visit a kernel_function. More precisely, the entry point for the visit will be the global corresponding to the last declaration/definition of the kf. The returned kf is the one that has the varinfo associated to the varinfo of the original kf. If this is a new kf, it is however the responsibility of the visitor to insert it in the AST at the appropriate place.

val visitFramacFunction : frama_c_visitor -> Cil_types.fundec -> Cil_types.fundec

Visit a function definition.

val visitFramacExpr : frama_c_visitor -> Cil_types.exp -> Cil_types.exp

Visit an expression

val visitFramacLval : frama_c_visitor -> Cil_types.lval -> Cil_types.lval

Visit an lvalue

val visitFramacOffset : frama_c_visitor -> Cil_types.offset -> Cil_types.offset

Visit an lvalue or recursive offset

val visitFramacInitOffset : frama_c_visitor -> Cil_types.offset -> Cil_types.offset

Visit an initializer offset

val visitFramacInstr : frama_c_visitor -> Cil_types.instr -> Cil_types.instr list

Visit an instruction

val visitFramacStmt : frama_c_visitor -> Cil_types.stmt -> Cil_types.stmt

Visit a statement

val visitFramacBlock : frama_c_visitor -> Cil_types.block -> Cil_types.block

Visit a block

val visitFramacType : frama_c_visitor -> Cil_types.typ -> Cil_types.typ

Visit a type

val visitFramacVarDecl : frama_c_visitor -> Cil_types.varinfo -> Cil_types.varinfo

Visit a variable declaration

val visitFramacLogicVarDecl : frama_c_visitor -> Cil_types.logic_var -> Cil_types.logic_var

Visit a logic variable declaration

val visitFramacInit : frama_c_visitor ->
       Cil_types.varinfo -> Cil_types.offset -> Cil_types.init -> Cil_types.init

Visit an initializer, pass also the global to which this belongs and the offset.

val visitFramacAttributes : frama_c_visitor ->
       Cil_types.attribute list -> Cil_types.attribute list

Visit a list of attributes

val visitFramacAnnotation : frama_c_visitor ->
       Cil_types.global_annotation -> Cil_types.global_annotation
val visitFramacCodeAnnotation : frama_c_visitor ->
       Cil_types.code_annotation -> Cil_types.code_annotation

val visitFramacDeps : frama_c_visitor -> Cil_types.deps -> Cil_types.deps
val visitFramacFunspec : frama_c_visitor -> Cil_types.funspec -> Cil_types.funspec
val visitFramacLogicType : frama_c_visitor -> Cil_types.logic_type -> Cil_types.logic_type
val visitFramacPredicateNode : frama_c_visitor ->
       Cil_types.predicate_node -> Cil_types.predicate_node
val visitFramacPredicate : frama_c_visitor -> Cil_types.predicate -> Cil_types.predicate
val visitFramacIdPredicate : frama_c_visitor ->
       Cil_types.identified_predicate -> Cil_types.identified_predicate
val visitFramacPredicates : frama_c_visitor ->
       Cil_types.identified_predicate list -> Cil_types.identified_predicate list
val visitFramacIdTerm : frama_c_visitor ->
       Cil_types.identified_term -> Cil_types.identified_term

visit identified_term.

val visitFramacTermLval : frama_c_visitor -> Cil_types.term_lval -> Cil_types.term_lval
val visitFramacTermLhost : frama_c_visitor -> Cil_types.term_lhost -> Cil_types.term_lhost
