A cross-platform library for retrieving per-address debug information from files with DWARF debug information.
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_frames, or via the included example binary,
addr2line (named and modelled after the equivalent utility from

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
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.
