22/* Objdump overview.
23
24 Objdump displays information about one or more object files, either on
25 their own, or inside libraries. It is commonly used as a disassembler,
26 but it can also display information about file headers, symbol tables,
27 relocations, debugging directives and more.
28
29 The flow of execution is as follows:
3aade688 30
155e0d23
NC
31 1. Command line arguments are checked for control switches and the
32 information to be displayed is selected.
3aade688 33
155e0d23
NC
34 2. Any remaining arguments are assumed to be object files, and they are
35 processed in order by display_bfd(). If the file is an archive each
36 of its elements is processed in turn.
3aade688 37
50c2245b 38 3. The file's target architecture and binary file format are determined
155e0d23
NC
39 by bfd_check_format(). If they are recognised, then dump_bfd() is
40 called.
41
50c2245b
KH
42 4. dump_bfd() in turn calls separate functions to display the requested
43 item(s) of information(s). For example disassemble_data() is called if
aaad4cf3 44 a disassembly has been requested.
155e0d23
NC
45
46 When disassembling the code loops through blocks of instructions bounded
50c2245b 47 by symbols, calling disassemble_bytes() on each block. The actual
155e0d23
NC
48 disassembling is done by the libopcodes library, via a function pointer
49 supplied by the disassembler() function. */
