// This utility works much like "addr2line". It is able of transforming
|
|
// tuples (module name, module offset) to code locations (function name,
|
|
// file, line number, column number). It is targeted for compiler-rt tools
|
|
// (especially AddressSanitizer and ThreadSanitizer) that can use it
|
|
// to symbolize stack traces in their error reports.
