| .IX Header "DESCRIPTION" |
| \&\fBaddr2line\fR 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. |
| .PP |
| The executable or relocatable object to use is specified with the \fB\-e\fR |
| option. The default is the file \fIa.out\fR. The section in the relocatable |
| object to use is specified with the \fB\-j\fR option. |
| .PP |
| \&\fBaddr2line\fR has two modes of operation. |
| .PP |
| In the first, hexadecimal addresses are specified on the command line, |
| and \fBaddr2line\fR displays the file name and line number for each |
| address. |
| .PP |
| In the second, \fBaddr2line\fR reads hexadecimal addresses from |
| standard input, and prints the file name and line number for each |
| address on standard output. In this mode, \fBaddr2line\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 input address is printed on separate lines. |
| .PP |
| If the \fB\-f\fR option is used, then each \fB\s-1FILENAME:LINENO\s0\fR |
| line is preceded by \fB\s-1FUNCTIONNAME\s0\fR which is the name of the |
| function containing the address. |
| .PP |
| If the \fB\-i\fR option is used and the code at the given address is |
| present there because of inlining by the compiler then the |
| \&\fB{\s-1FUNCTIONNAME\s0} \s-1FILENAME:LINENO\s0\fR information for the inlining |
| function will be displayed afterwards. This continues recursively |
| until there is no more inlining to report. |
| .PP |
| If the \fB\-a\fR option is used then the output is prefixed by the |
| input address. |
| .PP |
| If the \fB\-p\fR option is used then the output for each input |
| address is displayed on one, possibly quite long, line. If |
| \&\fB\-p\fR is not used then the output is broken up into multiple |
| lines, based on the paragraphs above. |
| .PP |
| If the file name or function name can not be determined, |
| \&\fBaddr2line\fR will print two question marks in their place. If the |
| line number can not be determined, \fBaddr2line\fR will print 0. |

| .PD |
| 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 "\fB\-\-functions\fR" 4 |

| .PD 0 |
| .IP "\fB\-\-inlines\fR" 4 |
| .IX Item "--inlines" |
| .PD |
| If the address belongs to a function that was inlined, the source |
| information for all enclosing scopes back to the first non-inlined |
| function will also be printed. For example, if \f(CW\*(C`main\*(C'\fR inlines |
| \&\f(CW\*(C`callee1\*(C'\fR which inlines \f(CW\*(C`callee2\*(C'\fR, and address is from |
| \&\f(CW\*(C`callee2\*(C'\fR, the source information for \f(CW\*(C`callee1\*(C'\fR and \f(CW\*(C`main\*(C'\fR |
| will also be printed. |

| .IX Item "-j" |

| .IP "\fB\-\-section\fR" 4 |
| .IX Item "--section" |

| .IX Item "-p" |
| .PD 0 |
| .IP "\fB\-\-pretty\-print\fR" 4 |
| .IX Item "--pretty-print" |
| .PD |
| Make the output more human friendly: each location are printed on one line. |
| If option \fB\-i\fR is specified, lines for all enclosing scopes are |
| prefixed with \fB(inlined by)\fR. |
| .IP "\fB@\fR\fIfile\fR" 4 |
| .IX Item "@file" |
| Read command-line options from \fIfile\fR. The options read are |
| inserted in place of the original @\fIfile\fR option. If \fIfile\fR |
| does not exist, or cannot be read, then the option will be treated |
| literally, and not removed. |
| .Sp |
| Options in \fIfile\fR 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 \fIfile\fR may itself contain additional |
| @\fIfile\fR options; any such options will be processed recursively. |
