From: Arnaldo Carvalho de Melo <[email protected]> The source code line number (lineno) needs to be kept in accross calls to symbol__parse_objdump_line() when parsing the output of 'objdump -l -dS', so that it can associate it with the instructions till the next line.
See disasm_line__new() and struct disasm_line::line_nr.
