/* Objdump overview.
Objdump displays information about one or more object files, either on
their own, or inside libraries. It is commonly used as a disassembler,
but it can also display information about file headers, symbol tables,
relocations, debugging directives and more.
The flow of execution is as follows:
2015-08-12 13:42:37 +02:00
1. Command line arguments are checked for control switches and the
information to be displayed is selected.
2015-08-12 13:42:37 +02:00
2. Any remaining arguments are assumed to be object files, and they are
processed in order by display_bfd(). If the file is an archive each
of its elements is processed in turn.
2015-08-12 13:42:37 +02:00
3. The file's target architecture and binary file format are determined
by bfd_check_format(). If they are recognised, then dump_bfd() is
called.
4. dump_bfd() in turn calls separate functions to display the requested
item(s) of information(s). For example disassemble_data() is called if
a disassembly has been requested.
When disassembling the code loops through blocks of instructions bounded
by symbols, calling disassemble_bytes() on each block. The actual
disassembling is done by the libopcodes library, via a function pointer
supplied by the disassembler() function. */
