Module `Goblint_lib.Edge`

CFG edge. Corresponds to a (primitive) program statement between program points (and their states).

type asm_out = (string option * string * CilType.Lval.t) list

val asm_out_to_yojson : asm_out -> Yojson.Safe.t

type asm_in = (string option * string * CilType.Exp.t) list

type t =

| Assign of CilType.Lval.t * CilType.Exp.t
(*
Assignments lval = exp
*)
| Proc of CilType.Lval.t option * CilType.Exp.t * CilType.Exp.t list
(*
Function calls of the form lva = fexp (e1, e2, ...)
*)
| Entry of CilType.Fundec.t
(*
Entry edge that relates function declaration to function body. You can use * this to initialize the local variables.
*)
| Ret of CilType.Exp.t option * CilType.Fundec.t
(*
Return edge is between the return statement, which may optionally contain * a return value, and the function. The result of the call is then * transferred to the function node!
*)
| Test of CilType.Exp.t * bool
(*
The true-branch or false-branch of a conditional exp
*)
| ASM of string list * asm_out * asm_in
(*
Inline assembly statements, and the annotations for output and input * variables.
*)
| VDecl of CilType.Varinfo.t
(*
VDecl edge for the variable in varinfo. Whether such an edge is there for all * local variables or only when it is not possible to pull the declaration up, is * determined by alwaysGenerateVarDecl in cabs2cil.ml in CIL. One case in which a VDecl * is always there is for VLA. If there is a VDecl edge, it is where the declaration originally * appeared
*)
| Skip
(*
This is here for historical reasons. I never use Skip edges!
