NAME
     unwinddump -- Displays compact unwind information in an executable

SYNOPSIS
     unwinddump [-arch arch-name] file(s)

DESCRIPTION
     When a C++ (or x86_64 Objective-C) exception is thrown, the runtime must unwind the stack looking for some function to catch the exception.
     Traditionally, the unwind information is stored in the __TEXT/__eh_frame section of each executable as Dwarf CFI (call frame information).
     Beginning in Mac OS X 10.6, the unwind information is also encoded in the __TEXT/__unwind_info section using a two-level lookup table of com-
     pact unwind encodings.

     The unwinddump tool displays the content of the __TEXT/__unwind_info section.
