[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 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 tiene dos modos de operación.
En el primero, se especifican en la línea de órdenes direcciones hexadecimales, y addr2line muestra el nombre del fichero y el número de línea para cada dirección.
En la segunda, addr2line lee direcciones exadecimales desde la entrada estándar, y muestra el nombre del fichero y el número de línea para cada dirección en la salida estándar. En este modo, addr2line puede emplearse en una interconexión para convertir dinámicamente direcciones escogidas.
The format of the output is FILENAME:LINENO. By default each input address generates one line of output.
Two options can generate additional lines before each FILENAME:LINENO line (in that order).
If the -a option is used then a line with the input address is displayed.
If the -f option is used, then a line with the FUNCTIONNAME is displayed. This is the name of the function containing the address.
One option can generate additional lines after the FILENAME:LINENO line.
If the -i option is used and the code at the given address is present there because of inlining by the compiler then additional lines are displayed afterwards. One or two extra lines (if the -f option is used) are displayed for each inlined function.
Alternatively if the -p option is used then each input address generates a single, long, output line containing the address, the function name, the file name and the line number. If the -i option has also been used then any inlined functions will be displayed in the same manner, but on separate lines, and prefixed by the text (inlined by).
Si el nombre de fichero o el de función no pueden determinarse, addr2line mostrará dos signos de interrogación en sus lugares. Si el número de línea no puede determinarse, addr2line mostrará el número 0.
The long and short forms of options, shown here as alternatives, are equivalent.
The default is for this limit to be enabled, but disabling it may be necessary in order to demangle truly complicated names. Note however that if the recursion limit is disabled then stack exhaustion is possible and any bug reports about such an event will be rejected.
The -r option is a synonym for the --no-recurse-limit option. The -R option is a synonym for the --recurse-limit option.
Note this option is only effective if the -C or --demangle option has been enabled.
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.
