Class type

A framework for data flow analysis for CIL code. Before using this framework, you must initialize the Control-flow Graph for your program, e.g using Cfg.computeFileCFG

type 't action =

| Default
(*
The default action
*)
| Done of 't
(*
Do not do the default action. Use this result
*)
| Post of 't -> 't
(*
The default action, followed by the given transformer
*)

type 't stmtaction =

| SDefault
(*
The default action
*)
| SDone
(*
Do not visit this statement or its successors
*)
| SUse of 't
(*
Visit the instructions and successors of this statement as usual, but use the specified state instead of the one that was passed to doStmt
*)

type 't guardaction =

| GDefault
(*
The default state
*)
| GUse of 't
(*
Use this data for the branch
*)
| GUnreachable
(*
The branch will never be taken.
*)

val find_stmts : Cil.fundec -> Cil.stmt list * Cil.stmt list

Returns (all_stmts, sink_stmts), where all_stmts is a list of the statements in a function, and sink_stmts is a list of the return statments (including statements that fall through the end of a void function). Useful when you need an initial set of statements for BackwardsDataFlow.compute.
