Module `Ir.Node`

IR Graph node.

Node is labeled by the blk term.

include Graphlib.Std.Node
  with type graph = t
   and type t = node
   and type edge = edge
   and type label = blk term

type t = node

node type is opaque

type graph = t

node type is opaque

type label = blk term

type edge = edge

val create : label -> t

create label creates a new node, and associates it with a a given label.

val label : t -> label

label n returns a value associated with a node n.

val mem : t -> graph -> bool

mem n g is true if n is a member of nodes N of graph g.

val succs : t -> graph -> t Regular.Std.seq

succs node graph returns a sequence of successors of a node in a a given graph

val preds : t -> graph -> t Regular.Std.seq

preds node graph returns a sequence of predecessors of a node in a a given graph

val inputs : t -> graph -> edge Regular.Std.seq

inputs node graph is incoming edges of a node in graph

val outputs : t -> graph -> edge Regular.Std.seq

outputs node graph is outcomming edges of a node in graph

val degree : ?dir:[ `In | `Out ] -> t -> graph -> int

degree ?dir n when in_or_out is `In then returns the amount of incoming edges, otherwise returns the amount of outcomming edges. If parameter dir is left absent, then return the amount of adjacent nodes (i.e., a sum of incoming and outcomming edges).

val insert : t -> graph -> graph

insert n g returns new graph g' that has a set of nodes N extended with node n. If N was contained n, then the g == g'. Use update to change existing nodes.

Postconditions:

- N(g') = N(g) ∪ {n}.

val update : t -> label -> graph -> graph

update n l g if node n is not in N(g) then return g, else return graph g where node n is labeled with l.

Postconditions:

- n ∉ N(g) -> n ∉ N(g').
- n ∈ N(g) → ν(g')n = l.

val remove : t -> graph -> graph

remove n g returns graph g', with a node n removed from a set of nodes N.

Postconditions:

- E(g) ⊆ E(g')
- N(g) ⊆ N(g')
- N(g') = N(g) \ {n}.

val has_edge : t -> t -> graph -> bool

has_edge x y g is true iff (x,y) ∈ E.

val edge : t -> t -> graph -> edge option

edge x y g if graph g has an edge between nodes x and y then it is returned.

node provides common data structures, like Table, Map, Set, Hash_set, etc.

include Core_kernel.Comparable.S with type t := t

include Base.Comparable.S with type t := t

val (>=) : t -> t -> bool

val (<=) : t -> t -> bool

val (=) : t -> t -> bool

val (>) : t -> t -> bool

val (<) : t -> t -> bool

val (<>) : t -> t -> bool

val equal : t -> t -> bool

val min : t -> t -> t

val max : t -> t -> t

val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int

val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

module Hash_queue : Core_kernel.Hash_queue.S with type Key.t = t

include Regular.Std.Printable.S with type t := t

val to_string : t -> string

to_string x returns a human-readable representation of x

val str : unit -> t -> string

str () t is formatted output function that matches "%a" conversion format specifier in functions, that prints to string, e.g., sprintf, failwithf, errorf and, surprisingly all Lwt printing function, including Lwt_io.printf and logging (or any other function with type ('a,unit,string,...) formatN`. Example:

Or_error.errorf "type %a is not valid for %a"
    Type.str ty Exp.str exp

val pps : unit -> t -> string

synonym for str

val ppo : Core_kernel.Out_channel.t -> t -> unit

will print to a standard output_channel, useful for using in printf, fprintf, etc.

val pp_seq : Format.formatter -> t Core_kernel.Sequence.t -> unit

prints a sequence of values of type t

this will include pp function from Core that has type t printer, and can be used in Format.printf family of functions

include Core_kernel.Pretty_printer.S with type t := t

val pp : Base__.Formatter.t -> t -> unit
