 152 .SH "DESCRIPTION"
 153 .IX Header "DESCRIPTION"
 154 \&\f(CW\*(C`addr2line\*(C'\fR translates program addresses into file names and line
 155 numbers.  Given an address and an executable, it uses the debugging
 156 information in the executable to figure out which file name and line
 157 number are associated with a given address.
 158 .PP
 159 The executable to use is specified with the \f(CW\*(C`\-e\*(C'\fR option.  The
 160 default is the file \fIa.out\fR.
 161 .PP
 162 \&\f(CW\*(C`addr2line\*(C'\fR has two modes of operation.
 163 .PP
 164 In the first, hexadecimal addresses are specified on the command line,
 165 and \f(CW\*(C`addr2line\*(C'\fR displays the file name and line number for each
 166 address.
 167 .PP
 168 In the second, \f(CW\*(C`addr2line\*(C'\fR reads hexadecimal addresses from
 169 standard input, and prints the file name and line number for each
 170 address on standard output.  In this mode, \f(CW\*(C`addr2line\*(C'\fR may be used
 171 in a pipe to convert dynamically chosen addresses.
 172 .PP
 173 The format of the output is \fB\s-1FILENAME:LINENO\s0\fR.  The file name and
 174 line number for each address is printed on a separate line.  If the
 175 \&\f(CW\*(C`\-f\*(C'\fR option is used, then each \fB\s-1FILENAME:LINENO\s0\fR line is
 176 preceded by a \fB\s-1FUNCTIONNAME\s0\fR line which is the name of the function
 177 containing the address.
 178 .PP
 179 If the file name or function name can not be determined,
 180 \&\f(CW\*(C`addr2line\*(C'\fR will print two question marks in their place.  If the
 181 line number can not be determined, \f(CW\*(C`addr2line\*(C'\fR will print 0.
 182 .SH "OPTIONS"
 183 .IX Header "OPTIONS"
 184 The long and short forms of options, shown here as alternatives, are
 185 equivalent.

 188 .Ip "\f(CW\*(C`\-\-target=\f(CIbfdname\f(CW\*(C'\fR" 4
 189 .IX Item "--target=bfdname"
 190 Specify that the object-code format for the object files is
 191 \&\fIbfdname\fR.
 192 .Ip "\f(CW\*(C`\-C\*(C'\fR" 4
 193 .IX Item "-C"
 194 .Ip "\f(CW\*(C`\-\-demangle[=\f(CIstyle\f(CW]\*(C'\fR" 4
 195 .IX Item "--demangle[=style]"
 196 Decode (\fIdemangle\fR) low-level symbol names into user-level names.
 197 Besides removing any initial underscore prepended by the system, this
 198 makes \*(C+ function names readable.  Different compilers have different
 199 mangling styles. The optional demangling style argument can be used to
 200 choose an appropriate demangling style for your compiler.

 202 .IX Item "-e filename"
 203 .Ip "\f(CW\*(C`\-\-exe=\f(CIfilename\f(CW\*(C'\fR" 4
 204 .IX Item "--exe=filename"
 205 Specify the name of the executable for which addresses should be
 206 translated.  The default file is \fIa.out\fR.
 207 .Ip "\f(CW\*(C`\-f\*(C'\fR" 4
 208 .IX Item "-f"
 209 .Ip "\f(CW\*(C`\-\-functions\*(C'\fR" 4
 210 .IX Item "--functions"
 211 Display function names as well as file and line number information.

 213 .IX Item "-s"
 214 .Ip "\f(CW\*(C`\-\-basenames\*(C'\fR" 4
 215 .IX Item "--basenames"
 216 Display only the base of each file name.
