26 Objdump displays information about one or more object files, either on
27 their own, or inside libraries. It is commonly used as a disassembler,
28 but it can also display information about file headers, symbol tables,
29 relocations, debugging directives and more.
31 The flow of execution is as follows:
33 1. Command line arguments are checked for control switches and the
34 information to be displayed is selected.
36 2. Any remaining arguments are assumed to be object files, and they are
37 processed in order by display_bfd(). If the file is an archive each
38 of its elements is processed in turn.
40 3. The file's target architecture and binary file format are determined
41 by bfd_check_format(). If they are recognised, then dump_bfd() is
44 4. dump_bfd() in turn calls separate functions to display the requested
45 item(s) of information(s). For example disassemble_data() is called if
46 a disassembly has been requested.
48 When disassembling the code loops through blocks of instructions bounded
49 by symbols, calling disassemble_bytes() on each block. The actual
50 disassembling is done by the libopcodes library, via a function pointer
51 supplied by the disassembler() function. */
