145 .IX Header "DESCRIPTION"
146 \&\fBaddr2line\fR translates addresses into file names and line numbers.
147 Given an address in an executable or an offset in a section of a relocatable
148 object, it uses the debugging information to figure out which file name and
149 line number are associated with it.
150 .PP
151 The executable or relocatable object to use is specified with the \fB\-e\fR
152 option. The default is the file \fIa.out\fR. The section in the relocatable
153 object to use is specified with the \fB\-j\fR option.
154 .PP
155 \&\fBaddr2line\fR has two modes of operation.
156 .PP
157 In the first, hexadecimal addresses are specified on the command line,
158 and \fBaddr2line\fR displays the file name and line number for each
159 address.
160 .PP
161 In the second, \fBaddr2line\fR reads hexadecimal addresses from
162 standard input, and prints the file name and line number for each
163 address on standard output. In this mode, \fBaddr2line\fR may be used
164 in a pipe to convert dynamically chosen addresses.
165 .PP
166 The format of the output is \fB\s-1FILENAME:LINENO\s0\fR. The file name and
167 line number for each address is printed on a separate line. If the
168 \&\fB\-f\fR option is used, then each \fB\s-1FILENAME:LINENO\s0\fR line is
169 preceded by a \fB\s-1FUNCTIONNAME\s0\fR line which is the name of the function
170 containing the address.
171 .PP
172 If the file name or function name can not be determined,
173 \&\fBaddr2line\fR will print two question marks in their place. If the
174 line number can not be determined, \fBaddr2line\fR will print 0.
175 .SH "OPTIONS"
176 .IX Header "OPTIONS"

193 Decode (\fIdemangle\fR) low-level symbol names into user-level names.
194 Besides removing any initial underscore prepended by the system, this
195 makes \*(C+ function names readable. Different compilers have different
196 mangling styles. The optional demangling style argument can be used to
197 choose an appropriate demangling style for your compiler.

226 If the address belongs to a function that was inlined, the source
227 information for all enclosing scopes back to the first non-inlined
228 function will also be printed. For example, if \f(CW\*(C`main\*(C'\fR inlines
229 \&\f(CW\*(C`callee1\*(C'\fR which inlines \f(CW\*(C`callee2\*(C'\fR, and address is from
230 \&\f(CW\*(C`callee2\*(C'\fR, the source information for \f(CW\*(C`callee1\*(C'\fR and \f(CW\*(C`main\*(C'\fR
231 will also be printed.

241 Read command-line options from \fIfile\fR. The options read are
242 inserted in place of the original @\fIfile\fR option. If \fIfile\fR
243 does not exist, or cannot be read, then the option will be treated
244 literally, and not removed.
245 .Sp
246 Options in \fIfile\fR are separated by whitespace. A whitespace
247 character may be included in an option by surrounding the entire
248 option in either single or double quotes. Any character (including a
249 backslash) may be included by prefixing the character to be included
250 with a backslash. The \fIfile\fR may itself contain additional
251 @\fIfile\fR options; any such options will be processed recursively.
