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>
-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
-s --basenames Strip directory names
-f --functions Show function names
-C --demangle[=style] Demangle function names
-h --help Display this information
-v --version Display the program's version
