addr2line

Build Status Coverage Status

A cross-platform library for retrieving per-address debug information from files with DWARF debug information.

addr2line uses gimli to parse the debug information, and exposes an interface for finding the source file, line number, and wrapping function for instruction addresses within the target program. These lookups can either be performed programmatically through Context::find_location and Context::find_frames, or via the included example binary, addr2line (named and modelled after the equivalent utility from GNU binutils).

Quickstart

Performance

addr2line optimizes for speed over memory by caching parsed information. The DWARF information is parsed lazily where possible.

The library aims to perform similarly to equivalent existing tools such as addr2line from binutils, eu-addr2line from elfutils, and llvm-symbolize from the llvm project, and in the past some benchmarking was done that indicates a comparable performance.
