Chapter 11.addr2lineaddr2line [-b bfdname|--target=bfdname][-C|--demangle[=style]][-e filename|--exe=filename][-f|--functions] [-s|--basename][-H|--help] [-V|--version][addr addr ...]addr2line translates program addresses into file names and line numbers. Given an address and anexecutable, it uses the debugging information in the executable to figure out which file name and linenumber are associated with a given address.The executable to use is specified with the -e option. The default is the file a.out.addr2line has two modes of operation.In the first, hexadecimal addresses are specified on the command line, and addr2line displays thefile name and line number for each address.In the second, addr2line reads hexadecimal addresses from standard input, and prints the file nameand line number for each address on standard output. In this mode, addr2line may be used in a pipeto convert dynamically chosen addresses.The format of the output is FILENAME:LINENO. The file name and line number for each address isprinted on a separate line. If the -f option is used, then each FILENAME:LINENO line is preceded bya FUNCTIONNAME line which is the name of the function containing the address.If the file name or function name can not be determined, addr2line will print two question marks intheir place. If the line number can not be determined, addr2line will print 0.The long and short forms of options, shown here as alternatives, are equivalent.-b bfdname-target=bfdnameSpecify that the object-code format for the object files is bfdname.-C-demangle[=style]Decode (demangle) low-level symbol names into user-level names. Besides removing any initialunderscore prepended by the system, this makes C++ function names readable. Different compil-ers have different mangling styles. The optional demangling style argument can be used to choosean appropriate demangling style for your compiler. Chapter 10 c++filt, for more information ondemangling.-e filename-exe=filenameSpecify the name of the executable for which addresses should be translated. The default file isa.out.
