Loader utility functions

val find_section_by_name : string -> Loader.Img.t -> Loader.Section.t
val section_slice_by_name : string -> Loader.Img.t -> int * int

section_slice section_name img returns the interval lo, hi of virtual addresses defining the section section_name.

val find_section_by_address : address:int -> Loader.Img.t -> Loader.Section.t option
val find_section_by_address_exn : address:int -> Loader.Img.t -> Loader.Section.t
  • raises Failure

    exception if no such section exists

val section_slice_by_address : address:int -> Loader.Img.t -> int * int
val find_section : p:(Loader.Section.t -> bool) -> Loader.Img.t -> Loader.Section.t option

Manipulation of symbols *

Functions that are of the form f_by_name call the function symbol_by_name which is costly because it compares all the symbols in the image to the requested name. Use them with parcimony and cache the symbols if they are requested multiple times.

val symbol_by_name : name:Stdlib.String.t -> Loader.Img.t -> Loader.Symbol.t option

symbol_by_name ~name img Returns Some symbol name in img. If img contains no symbol name, returns None.

val address_of_symbol : Loader.Symbol.t -> int

address_of_symbol symbol finds Some address where the symbole is defined. Otherwise returns None.

val address_of_symbol_by_name : name:string -> Loader.Img.t -> int option
val size_of_symbol : Loader.Symbol.t -> int
val size_of_symbol_by_name : name:string -> Loader.Img.t -> int option

symbol_interval symbol Returns the address range corresponding to symbol

val symbol_interval_by_name : name:string -> Loader.Img.t -> (Virtual_address.t * Virtual_address.t) option
val belongs_to_symbol : Loader.Symbol.t -> Virtual_address.t -> bool

belongs_to_symbol symbol addr Returns true if the address addr is locate in the symbol (i.e. in the range address_of_symbol symbol (included) and address_of_symbol symbol + size_of_symbol symbol_interval (excluded)).

val belongs_to_symbol_by_name : name:string -> Loader.Img.t -> Virtual_address.t -> bool
val address_of_symbol_or_section_by_name : name:string -> Loader.Img.t -> int option
val size_of_symbol_or_section_by_name : name:string -> Loader.Img.t -> int option
val interval_of_symbol_or_section_by_name : name:string -> Loader.Img.t -> (Virtual_address.t * Virtual_address.t) option
val get_byte_at : Loader.Img.t -> Bitvector.t -> int
val entry_point : Loader.Img.t -> Virtual_address.t
