Some useful utilities for STAB debug information parsing

Some useful utilities STAB debuginfo related utilities that may be helpful in reversing.

Missing dependencies, or get ModuleNotFoundError? Install them with python3 -m pip

ELF to split STAB section

Supports reading .stab, .stabstr, and .mdebug section.
.mdebug section will be converted to the .stab and .stabstr specification.
Limitations:

• 32-bit support only

Usage:

python3 /path/to/elf_to_split_stab.py /path/to/input/file.elf /path/to/output/file.stab /path/to/output/file.stabstr

Split STAB section to ELF

Supports reading .stab, and .stabstr pre-split files.
Limitations:

• 32-bit support only

Usage:

python3 /path/to/split_stab_to_elf.py /path/to/input/file.stab /path/to/input/file.stabstr /path/to/output/file.elf

STABS debug info to JSON

A patch to prdbg.c from GNU Binutils that will output the information in JSON format.
Some functionality (like C++ data types) are not implemented properly.

JSON to the scripting format of an industry-leading disassembler

json2pcode.py converts the output of the above "STABS debug info to JSON" to the scripting format of an industry-leading disassembler.
Known missing/incomplete features:

• C++ types
• Static and register local variables
• 64-bit support

Due to interdependency issues, you need to run the generated script twice.
