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: - - 1. Command line arguments are checked for control switches and the - information to be displayed is selected. - - 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. - - 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. */ - -#include "sysdep.h" -#include "bfd.h" -#include "elf-bfd.h" -#include "progress.h" -#include "bucomm.h" -#include "elfcomm.h" -#include "dwarf.h" -#include "getopt.h" -#include "safe-ctype.h" -#include "dis-asm.h" -#include "libiberty.h" -#include "demangle.h" -#include "filenames.h" -#include "debug.h" -#include "budbg.h" -#include "objdump.h" - -#ifdef HAVE_MMAP -#include <sys/mman.h> -#endif - -/* Internal headers for the ELF .stab-dump code - sorry. */ -#define BYTES_IN_WORD 32 -#include "aout/aout64.h" - -/* Exit status. */ -static int exit_status = 0;
