Module `Magic_trace_core.Elf`Source

include module type of Elf_intf

Sourcemodule Location : sig ... end

Sourcemodule Addr_table : sig ... end

Sourcemodule Stop_info : sig ... end

Sourcetype t

Sourceval create : Core.Filename.t -> t option

Source

val symbol_stop_info : 
  t ->
  Core.Pid.t ->
  Owee_elf.Symbol_table.Symbol.t ->
  Stop_info.t

Returns name, address and filter string for using a symbol as a snapshot point.

The address is suitable for placing a breakpoint, and the filter string causes tracing to stop when executing code from that symbol. The filter string syntax is in ftrace format and is accepted both by the perf command line tool and the PERF_EVENT_IOC_SET_FILTER ioctl for the perf_event_open syscall.

Sourceval addr_table : t -> Addr_table.t

Source

val matching_functions : 
  t ->
  Re.re ->
  Owee_elf.Symbol_table.Symbol.t Core.String.Map.t

Find function symbols matching a regex and return a map from symbol name to symbol suitable for asking the user to disambiguate.

Sourceval all_symbols : t -> (string * Owee_elf.Symbol_table.Symbol.t) list

Sourceval find_symbol : t -> string -> Owee_elf.Symbol_table.Symbol.t option

Sourcemodule Symbol_resolver : sig ... end
