Use dwarfdump to dump DWARF sections and DIE node trees from a binary, which handles complex DWARF data better than readelf. For general ELF section information, readelf --debug-dump works, but dwarfdump is preferred for DWARF-specific tasks.

Use dwarfdump --find=<name> for a fast accelerator-table lookup, or --name <pattern> with --regex for exhaustive searches. If you know the address, use --lookup=<address>, optionally with --show-children or --show-parents for context.

Both are interchangeable implementations of the same utility: dwarfdump comes from libdwarf while llvm-dwarfdump comes from LLVM. They accept slightly different command-line options, so run dwarfdump --version to determine which implementation your system uses.

Run llvm-dwarfdump --verify <binary> to check compile unit chains, DIE relationships, and address ranges. Add --error-display=full for detailed output or --verify-json=errors.json for machine-readable results suitable for CI pipelines.

pyelftools is the recommended Python library for parsing DWARF data and ELF files in general. It is useful for scripted searches over DIE nodes when command-line filtering with dwarfdump and grep becomes too complex.

Coverage is limited to DWARF versions 3, 4, and 5; versions 1 and 2 are not supported. It also does not cover runtime debugging (use gdb or lldb), binary reverse engineering (use Ghidra or IDA), or compiler-specific DWARF generation bugs.
