Module `Dba.LValue`

type t = private

| Var of Var.t
| Restrict of Var.t * int Interval.t
| Store of size * Machine.endianness * Expr.t * string option

include Sigs.Eq with type t := t

val equal : t -> t -> bool

val size_of : t -> int

size_of lv yields the size of lv in bits *

val var : ?tag:Var.Tag.t -> bitsize:Size.Bit.t -> string -> t

var tag name ~size creates a DBA lvalue for a variable

val v : Var.t -> t

val flag : ?bitsize:Size.Bit.t -> string -> t

flag ~size fname creates a flag variable.

size defaults to 1

val temporary : string -> Size.Bit.t -> t

val _restrict : string -> Size.Bit.t -> int -> int -> t

val _bit_restrict : string -> Size.Bit.t -> int -> t

_restrict and _bit_restrict are deprecated. Use the other forms ** below.

val restrict : Var.t -> int -> int -> t

val bit_restrict : Var.t -> int -> t

val store : ?array:string -> Size.Byte.t -> Machine.endianness -> Expr.t -> t

val temp : Size.Bit.t -> t

temp n creates a lvalue representing a temporary of size n with name Format.sprintf "temp%d" n.

val is_expr_translatable : Expr.t -> bool

is_expr_translatable e returns true is the expression can have a valid lvalue translation

val of_expr : Expr.t -> t

of_expr e translates an expression to its lvalue equivalent if possible.

Use is_expr_translatable e to check the feasability of this translation.

raises Failure
"LValue.of_expr ..." if it is not possible.

val to_expr : t -> Expr.t

to_expr e translates an lvalue to its equivalent rvalue.

val bitsize : t -> Size.Bit.t

bitsize lv returns the size in bits of lv.

val resize : Size.Bit.t -> t -> t

resize bitsize lv patches the lvalue lv and gives it a size of bitsize.
