DWARF Expert

Interact with and analyze DWARF debug files, understand the DWARF debug format/standard, and write code that parses DWARF data.

Author: Evan Hellman

When to Use

Use this skill when you need to:

• Understand or parse DWARF debug information from compiled binaries
• Answer questions about the DWARF standard (v3, v4, v5)
• Write or review code that interacts with DWARF data
• Use dwarfdump or readelf to extract debug information
• Verify DWARF data integrity using llvm-dwarfdump --verify
• Work with DWARF parsing libraries (libdwarf, pyelftools, gimli, etc.)

What It Does

This skill provides expertise on:

• DWARF standards (v3-v5) via web search and authoritative source references
• Parsing DWARF files using dwarfdump and readelf commands
• Verification workflows using llvm-dwarfdump --verify and --statistics
• Library recommendations for DWARF parsing in C/C++, Python, Rust, Go, and .NET
• DIE (Debug Information Entry) analysis and searching
• Understanding DWARF sections, attributes, and forms

Authoritative Sources

This skill uses the following authoritative sources for DWARF standard information:

• dwarfstd.org: Official DWARF specification (via web search)
• LLVM source: llvm/lib/DebugInfo/DWARF/ for reference implementations
• libdwarf source: github.com/davea42/libdwarf-code for C implementations
