1.Addr2line 简介和安装

Addr2line 是一个用于将程序计数器（PC）地址转换为源代码文件名和行号的工具。它通常用于调试程序时查找特定地址对应的源代码位置。Addr2line 通常与调试符号文件（.debug文件）一起使用，以便能够正确地解析地址到源代码的映射关系。Addr2line 是 GNU binutils 工具集的一部分。

2.Addr2line 使用

$addr2line -h
Usage: addr2line [option(s)] [addr(s)]
 Convert addresses into line number/file name pairs.
 If no addresses are specified on the command line, they will be read from stdin
 The options are:
  @<file>                Read options from <file>
  -a --addresses         Show addresses
  -b --target=<bfdname>  Set the binary file format
  -e --exe=<executable>  Set the input file name (default is a.out)
  -i --inlines           Unwind inlined functions
  -j --section=<name>    Read section-relative offsets instead of addresses
  -p --pretty-print      Make the output easier to read for humans
  -s --basenames         Strip directory names
  -f --functions         Show function names
  -C --demangle[=style]  Demangle function names
  -R --recurse-limit     Enable a limit on recursion whilst demangling.  [Default]
  -r --no-recurse-limit  Disable a limit on recursion whilst demangling
  -h --help              Display this information
  -v --version           Display the program's version
