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. */ | |
