addr2line - convert addresses into file names and line numbers. 


addr2line [-a|--addresses]
          [-b bfdname|--target=bfdname]
          [-e filename|--exe=filename]
          [-f|--functions] [-s|--basename]
          [-H|--help] [-V|--version]
          [addr addr ...] 


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

The executable or relocatable object to use is specified with the -eoption. The default is the file a.out. The section in the relocatableobject 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 eachaddress.

In the second, addr2line reads hexadecimal addresses fromstandard input, and prints the file name and line number for eachaddress on standard output. In this mode, addr2line may be usedin a pipe to convert dynamically chosen addresses.

The format of the output is FILENAME:LINENO. The file name andline number for each address is printed on a separate line. If the-f option is used, then each FILENAME:LINENO line ispreceded by a FUNCTIONNAME line which is the name of the functioncontaining the address. If the -a option is used, then theaddress read is first printed.

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


The long and short forms of options, shown here as alternatives, areequivalent.
Display address before function names or file and line numberinformation. The address is printed with a 0x prefix to easilyidentify it.
-b bfdname
Specify that the object-code format for the object files isbfdname.
Decode (demangle) low-level symbol names into user-level names.Besides removing any initial underscore prepended by the system, thismakes C++ function names readable. Different compilers have differentmangling styles. The optional demangling style argument can be used tochoose an appropriate demangling style for your compiler.
-e filename
Specify the name of the executable for which addresses should betranslated. The default file is a.out.
Display function names as well as file and line number information.
Display only the base of each file name.
If the address belongs to a function that was inlined, the sourceinformation for all enclosing scopes back to the first non-inlinedfunction 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.
Read offsets relative to the specified section instead of absolute addresses.
Make the output more human friendly: each location are printed on one line.If option -i is specified, lines for all enclosing scopes areprefixed with (inlined by).
Read command-line options from file. The options read areinserted in place of the original @file option. If filedoes not exist, or cannot be read, then the option will be treatedliterally, and not removed.

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