ADDR2LINE(1)          GNU Development Tools          ADDR2LINE(1)

NAME

     addr2line - convert addresses into file names and line
     numbers.

SYNOPSIS

     addr2line [-b bfdname|--target=bfdname]
               [-C|--demangle[=style]]
               [-e filename|--exe=filename]
               [-f|--functions] [-s|--basename]
               [-i|--inlines]
               [-H|--help] [-V|--version]
               [addr addr ...]

DESCRIPTION

     addr2line translates program addresses into file names and
     line numbers.  Given an address and an executable, it uses
     the debugging information in the executable to figure out
     which file name and line number are associated with a given
     address.

     The executable to use is specified with the -e option.  The
     default is the file a.out.

     addr2line has two modes of operation.

     In the first, hexadecimal addresses are specified on the
     command line, and addr2line displays the file name and line
     number for each address.

     In the second, addr2line reads hexadecimal addresses from
     standard input, and prints the file name and line number for
     each address on standard output.  In this mode, addr2line
     may be used in a pipe to convert dynamically chosen
     addresses.

     The format of the output is FILENAME:LINENO.  The file name
     and line number for each address is printed on a separate
     line.  If the -f option is used, then each FILENAME:LINENO
     line is preceded by a FUNCTIONNAME line which is the name of
     the function containing the address.

     If the file name or function name can not be determined,
     addr2line will print two question marks in their place.  If
     the line number can not be determined, addr2line will print
     0.

OPTIONS

     The long and short forms of options, shown here as
     alternatives, are equivalent.

     -b bfdname
     --target=bfdname

ADDR2LINE(1)          GNU Development Tools          ADDR2LINE(1)

         Specify that the object-code format for the object files
         is bfdname.

     -C
     --demangle[=style]
         Decode (demangle) low-level symbol names into user-level
         names. Besides removing any initial underscore prepended
         by the system, this makes C++ function names readable.
         Different compilers have different mangling styles. The
         optional demangling style argument can be used to choose
         an appropriate demangling style for your compiler.

     -e filename
     --exe=filename
         Specify the name of the executable for which addresses
         should be translated.  The default file is a.out.

     -f
     --functions
         Display function names as well as file and line number
         information.

     -s
     --basenames
         Display only the base of each file name.

     -i
     --inlines
         If the address belongs to a function that was inlined,
         the source information for all enclosing scopes back to
         the first non-inlined function will also be printed.
         For example, if "main" inlines "callee1" which inlines
         "callee2", and address is from "callee2", the source
         information for "callee1" and "main" will also be
         printed.
