NAME

addr2line - convert addresses into file names and line numbers.

SYNOPSIS

addr2line [--bb _b_f_d_n_a_m_e|----ttaarrggeett==_b_f_d_n_a_m_e] [--CC|----ddeemmaannggllee[=_s_t_y_l_e]] [--ee _f_i_l_e_n_a_m_e|----eexxee==_f_i_l_e_n_a_m_e] [--ff|----ffuunnccttiioonnss] [--ss|----bbaasseennaammee] [--HH|----hheellpp] [--VV|----vveerrssiioonn] [addr addr ...]

DESCRIPTION

aaddddrr22lliinnee 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.

The executable to use is specified with the --ee option. The default is the file _a_._o_u_t.

aaddddrr22lliinnee has two modes of operation.

In the first, hexadecimal addresses are specified on the command line, and aaddddrr22lliinnee displays the file name and line number for each address.

In the second, aaddddrr22lliinnee reads hexadecimal addresses from standard input, and prints the file name and line number for each address on standard output. In this mode, aaddddrr22lliinnee may be used in a pipe to convert dynamically chosen addresses.

The format of the output is FFIILLEENNAAMMEE::LLIINNEENNOO. The file name and line number for each address is printed on a separate line. If the --ff option is used, then each FFIILLEENNAAMMEE::LLIINNEENNOO line is preceded by a FFUUNNCCTTIIOONNNNAAMMEE line which is the name of the function containing the address.

If the file name or function name can not be determined, aaddddrr22lliinnee will print two question marks in their place. If the line number can not be determined, aaddddrr22lliinnee will print 0.

OPTIONS

The long and short forms of options, shown here as alternatives, are equivalent.
--bb _b_f_d_n_a_m_e
----ttaarrggeett==_b_f_d_n_a_m_e Specify that the object-code format for the object files is
_b_f_d_n_a_m_e.
--CC
----ddeemmaannggllee[[==_s_t_y_l_e]] Decode (_d_e_m_a_n_g_l_e) 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.
--ee _f_i_l_e_n_a_m_e
----eexxee==_f_i_l_e_n_a_m_e Specify the name of the executable for which addresses should be
translated. The default file is _a_._o_u_t.
--ff
----ffuunnccttiioonnss Display function names as well as file and line number information.
--ss
----bbaasseennaammeess Display only the base of each file name.
