24 | /* Objdump overview. |
25 | ||
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. | |
30 | ||
31 | The flow of execution is as follows: | |
32 | ||
33 | 1. Command line arguments are checked for control switches and the | |
34 | information to be displayed is selected. | |
35 | ||
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. | |
39 | ||
50c2245b | 40 | 3. The file's target architecture and binary file format are determined |
155e0d23 NC |
41 | by bfd_check_format(). If they are recognised, then dump_bfd() is |
42 | called. | |
43 | ||
50c2245b KH |
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 | |
aaad4cf3 | 46 | a disassembly has been requested. |
155e0d23 NC |
47 | |
48 | When disassembling the code loops through blocks of instructions bounded | |
50c2245b | 49 | by symbols, calling disassemble_bytes() on each block. The actual |
155e0d23 NC |
50 | disassembling is done by the libopcodes library, via a function pointer |
51 | supplied by the disassembler() function. */ | |
