Build Status Coverage Status

gimli is a blazing fast library for consuming the DWARF debugging format.

  • Zero copy: everything is just a reference to the original input buffer. No copies of the input data get made.

  • Lazy: you can iterate compilation units without parsing their contents. Parse only as many debugging information entry (DIE) trees as you iterate over. gimli also uses DW_AT_sibling references to avoid parsing a DIE's children to find its next sibling, when possible.

  • Cross-platform: gimli makes no assumptions about what kind of object file you're working with. The flipside to that is that it's up to you to provide an ELF loader on Linux or Mach-O loader on OSX.

    • Unsure which object file parser to use? Try the cross-platform object crate. See the examples/ directory for usage with gimli.

Install

Add this to your Cargo.toml:

[dependencies]
gimli = "0.16.1"

Documentation

  • Documentation on docs.rs

  • Example programs:

    • A dwarfdump clone

    • An addr2line clone

    • ddbug, a utility giving insight into code generation by making debugging information readable

    • dwprod, a tiny utility to list the compilers used to create each compilation unit within a shared library or executable (via DW_AT_producer)

    • dwarf-validate, a program to validate the integrity of some DWARF and its references between sections and ocmpilation units.
