Module WitnessConstraints.PathSensitive3
Add path sensitivity to a analysis
Parameters
module Spec : Analyses.SpecSignature
module C : Printable.Smodule V : Analyses.SpecSysVarGlobal constraint variables.
module P : DisjointDomain.Representative with type elt := D.tGlobal constraint variables.
Auxiliary data (outside of solution domains) that needs to be marshaled and unmarshaled. This includes: * hashtables, * varinfos (create_var), * RichVarinfos.
val init : marshal option -> unitInitialize using unmarshaled auxiliary data (if present).
val finalize : unit -> marshalFinalize and return auxiliary data to be marshaled.

(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.lval ->
GoblintCil.exp ->
D.tA transfer function which handles the assignment of a rval to a lval, i.e., it handles program points of the form "lval = rval;"
val vdecl : (D.t, G.t, C.t, V.t) Analyses.ctx -> GoblintCil.varinfo -> D.tA transfer function used for declaring local variables. By default only for variable-length arrays (VLAs).
val branch : (D.t, G.t, C.t, V.t) Analyses.ctx -> GoblintCil.exp -> bool -> D.tA transfer function which handles conditional branching yielding the truth value passed as a boolean argument
val body : (D.t, G.t, C.t, V.t) Analyses.ctx -> GoblintCil.fundec -> D.tA transfer function which handles going from the start node of a function (fundec) into its function body. Meant to handle, e.g., initialization of local variables
val return :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.exp option ->
GoblintCil.fundec ->
D.tA transfer function which handles the return statement, i.e., "return exp" or "return" in the passed function (fundec)
A transfer function meant to handle inline assembler program points
A transfer function which works as the identity function, i.e., it skips and does nothing. Used for empty loops.
val special :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.lval option ->
GoblintCil.varinfo ->
GoblintCil.exp list ->
D.tA transfer function which, for a call to a special function f "lval = f(args)" or "f(args)", computes the caller state after the function call
val enter :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.lval option ->
GoblintCil.fundec ->
GoblintCil.exp list ->
(D.t * D.t) listFor a function call "lval = f(args)" or "f(args)", enter returns a caller state, and the initial state of the callee. In enter, the caller state can usually be returned unchanged, as combine_env and combine_assign (below) will compute the caller state after the function call, given the return state of the callee
val combine_env :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.lval option ->
GoblintCil.exp ->
GoblintCil.fundec ->
GoblintCil.exp list ->
C.t option ->
D.t ->
Queries.ask ->
D.tCombine environment (global variables, mutexes, etc) between local state (first component from enter) and function return.
This shouldn't yet assign to the lval.
val combine_assign :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
GoblintCil.lval option ->
GoblintCil.exp ->
GoblintCil.fundec ->
GoblintCil.exp list ->
C.t option ->
D.t ->
Queries.ask ->
D.tCombine return value assignment to local state (result from combine_env) and function return.
This should only assign to the lval.
val threadenter :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
multiple:bool ->
GoblintCil.lval option ->
GoblintCil.varinfo ->
GoblintCil.exp list ->
D.t listReturns initial state for created thread.
val threadspawn :
(D.t, G.t, C.t, V.t) Analyses.ctx ->
multiple:bool ->
GoblintCil.lval option ->
GoblintCil.varinfo ->
GoblintCil.exp list ->
(D.t, G.t, C.t, V.t) Analyses.ctx ->
D.tUpdates the local state of the creator thread using initial state of created thread.
