[-f | --functions]
[-i | --inlines]

DESCRIPTION
Theaddr2line utility translates program addresses
specified by the command line arguments hexaddress to
their corresponding source file names and line numbers. If no arguments are
given to addr2line, it will read these addresses from
standard input.
Program addresses specified by arguments hexaddress are encoded using the conventions accepted by strtoull(3).
By default, addr2line will use the
executable “a.out”. The
-e option may be used to specified a different ELF
object.
The addr2line utility recognizes the
following options:
-a|--addresses- Display the address prior to the line number information.
-btarget |--target=target- This option is recognized by
addr2linebut is ignored. It is supported for compatibility with GNU binutils. -epathname |--exe=pathname- Use the ELF object specified by argument pathname to
translate addresses. If this option is not specified,
addr2linewill use the file “a.out”. -f|--functions- Display function names in addition to file and line number information.
-i|--inlines- If the address specified belongs to an inlined function, also display the line number information for its caller, recursively until the first non-inlined caller.
-jsectionname |--section=sectionname- The values specified by arguments hexaddress are to be treated as offsets into the section named sectionname.
-p|--pretty-print- Display the line number information on one line, in human readable manner.
-s|--basename- Display only the base name for each file name.
-C|--demangle- Demangle C++ names.
-H|--help- Print a help message.
-V|--version- Print a version identifier and exit.
OUTPUT FORMAT
If the -f option was not specified,
addr2line will print the file name and line number
for each address specified on a separate line.
If the -f option was specified,
addr2line will print a line containing the name of
the function corresponding to program address
hexaddress, followed by a line with the file name and
line number.
If the -p option was specified,
addr2line will print line number information and
function name on one line in human readable manner. If the
-i option was also specified,
addr2line will print the caller function information
prefixed with “(inlined by)”.
The addr2line utility prints the file name
and line number using the format “FILENAME:LINENUMBER”.
If a file or function name could not be determined,
addr2line will print a question mark in their place.
If the line number could not be determined,
addr2line will print a zero in its place.
EXAMPLES
To map address 080483c4 in the default executable a.out to a source file name and line number use:
To map address 080483c4 in executable helloworld, use:
To have addr2line act as a filter reading
addresses from its standard input use:
To print the function name corresponding to an address in addition to its source file and line number use:
EXIT STATUS
The addr2line utility exits 0 on
success, and >0 if an error occurs.
