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]
                 [-j|--section=name]
                 [-H|--help] [-V|--version]
                 [addr addr ...]

DESCRIPTION
       addr2line translates addresses into file names and line numbers.  Given an address in an executable or an
       offset in a section of a relocatable object, it uses the debugging information to figure out which file name
       and line number are associated with it.

       The executable or relocatable object to use is specified with the -e option.  The default is the file a.out.
       The section in the relocatable object to use is specified with the -j option.

       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
           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.

       -j
       --section
           Read offsets relative to the specified section instead of absolute addresses.

       @file
           Read command-line options from file.  The options read are inserted in place of the original @file option.
           If file does not exist, or cannot be read, then the option will be treated literally, and not removed.

           Options in file are separated by whitespace.  A whitespace character may be included in an option by
           surrounding the entire option in either single or double quotes.  Any character (including a backslash) may
           be included by prefixing the character to be included with a backslash.  The file may itself contain
           additional @file options; any such options will be processed recursively.
