Overview

This skill provides technical knowledge and expertise about the DWARF standard and how to interact with DWARF files. Tasks include answering questions about the DWARF standard, providing examples of various DWARF features, parsing and/or creating DWARF files, and writing/modifying/analyzing code that interacts with DWARF data.

When to Use This Skill

• Understanding or parsing DWARF debug information from compiled binaries
• Answering questions about the DWARF standard (v3, v4, v5)
• Writing or reviewing code that interacts with DWARF data
• Using dwarfdump or readelf to extract debug information
• Verifying DWARF data integrity with llvm-dwarfdump --verify
• Working with DWARF parsing libraries (libdwarf, pyelftools, gimli, etc.)

When NOT to Use This Skill

• DWARF v1/v2 Analysis: Expertise limited to versions 3, 4, and 5.
• General ELF Parsing: Use standard ELF tools if DWARF data isn't needed.
• Executable Debugging: Use dedicated debugging tools (gdb, lldb, etc) for debugging executable code/runtime behavior.
• Binary Reverse Engineering: Use dedicated RE tools (Ghidra, IDA) unless specifically analyzing DWARF sections.
• Compiler Debugging: DWARF generation issues are compiler-specific, not covered here.
