NAME

     xrefs - Find crossed assembly references

SYNOPSIS

     xrefs [-vqVhe] [-a arch] [-f from] [-t to] [-r range] [-s size]
           [-d offset] [-X offset] [file] [offset]

DESCRIPTION

     This program is part of the radare project.

     Find crossed references to a certain offset on x86, arm and powerpc
     binaries. It supports options for swaping endiannes.

     This program can’t autodetect xrefs done by registers or data pointers.
     Only relative ones in jumps or calls.

     Xrefs autodetects the binary architecture parsing the ELF or PE headers
     found in the target file.

     -v          Verbose mode. Useful for debugging.

     -q          Quite mode. Useful for scripting. Shows the resulting offset
                 number.

     -V          Show version information and exits.

     -e          Use big endian instead of little endian when searching the
                 related offsets. It’s automatically defined by the ’-a’ flag
                 when choosing the target architecture.

     -a arch     Selects the architecture to be used. Available options:
                 ’x86’, ’arm’ and ’ppc’.

     -f from     Start looking for related offsets at a certain seek inside
                 the file.

     -t to       Finish xrefs search at a certain offset of the target file.

     -r range    Cut range of valid xrefs. This flag can be used instead of
                 the ’-f’ and ’-t’ flags.

     -s size     Define the size of the offset variable. (4 bytes for x86 and
                 3 for arm and powerpc). This value is automatically defined
                 by the ’-a’ flag.

     -d offset   Sets a negative delta offset as padding. This is normally the
                 size of the jump/call opcode.

     -X offset   Print out debugging information at a certain offset. This
                 flag is for debugging purposes only. See ’-v’

     -h          Show usage help message.

HACKING

     This program has been written with poor extensibility in mind. So it can
     probably be buggy on other architectures using them from the commandline.
     Feel free to send your parches, tips and ideas.

     This program has been tested on firmwares, bootloaders, ELF and PE
     binaries on x86, ppc and arm architectures.

     You can use the ’-X’ and ’-v’ flags for debugging the xrefs search
     engine.
