# 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:
```bash
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:
```bash
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.
