| .UC |
| .SH "NAME" |
| addr2line \- convert addresses into file names and line numbers. |
| .SH "SYNOPSIS" |
| .IX Header "SYNOPSIS" |
| addr2line [ \-b \fIbfdname\fR | \-\-target=\fIbfdname\fR ] |
| [ \-C | \-\-demangle[=\fIstyle\fR ] |
| [ \-e \fIfilename\fR | \-\-exe=\fIfilename\fR ] |

| [ addr addr ... ] |
| .SH "DESCRIPTION" |
| .IX Header "DESCRIPTION" |
| \&\f(CW\*(C`addr2line\*(C'\fR 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. |
| .PP |
| The executable to use is specified with the \f(CW\*(C`\-e\*(C'\fR option. The |
| default is the file \fIa.out\fR. |
| .PP |
| \&\f(CW\*(C`addr2line\*(C'\fR has two modes of operation. |
| .PP |
| In the first, hexadecimal addresses are specified on the command line, |
| and \f(CW\*(C`addr2line\*(C'\fR displays the file name and line number for each |
| address. |
| .PP |
| In the second, \f(CW\*(C`addr2line\*(C'\fR reads hexadecimal addresses from |
| standard input, and prints the file name and line number for each |
| address on standard output. In this mode, \f(CW\*(C`addr2line\*(C'\fR may be used |
| in a pipe to convert dynamically chosen addresses. |
| .PP |
| The format of the output is \fB\s-1FILENAME:LINENO\s0\fR. The file name and |
| line number for each address is printed on a separate line. If the |
| \&\f(CW\*(C`\-f\*(C'\fR option is used, then each \fB\s-1FILENAME:LINENO\s0\fR line is |
| preceded by a \fB\s-1FUNCTIONNAME\s0\fR line which is the name of the function |
| containing the address. |
| .PP |
| If the file name or function name can not be determined, |
| \&\f(CW\*(C`addr2line\*(C'\fR will print two question marks in their place. If the |
| line number can not be determined, \f(CW\*(C`addr2line\*(C'\fR will print 0. |
| .SH "OPTIONS" |
| .IX Header "OPTIONS" |
| The long and short forms of options, shown here as alternatives, are |
| equivalent. |
| .Ip "\f(CW\*(C`\-b \f(CIbfdname\f(CW\*(C'\fR" 4 |
| .IX Item "-b bfdname" |
| .Ip "\f(CW\*(C`\-\-target=\f(CIbfdname\f(CW\*(C'\fR" 4 |
| .IX Item "--target=bfdname" |
| Specify that the object-code format for the object files is |
| \&\fIbfdname\fR. |
| .Ip "\f(CW\*(C`\-C\*(C'\fR" 4 |
| .IX Item "-C" |
| .Ip "\f(CW\*(C`\-\-demangle[=\f(CIstyle\f(CW]\*(C'\fR" 4 |
| .IX Item "--demangle[=style]" |
| Decode (\fIdemangle\fR) 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. |
| .Ip "\f(CW\*(C`\-e \f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "-e filename" |
| .Ip "\f(CW\*(C`\-\-exe=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--exe=filename" |
| Specify the name of the executable for which addresses should be |
| translated. The default file is \fIa.out\fR. |
| .Ip "\f(CW\*(C`\-f\*(C'\fR" 4 |
| .IX Item "-f" |
| .Ip "\f(CW\*(C`\-\-functions\*(C'\fR" 4 |
| .IX Item "--functions" |
| Display function names as well as file and line number information. |

| .IX Item "-s" |
| .Ip "\f(CW\*(C`\-\-basenames\*(C'\fR" 4 |
