PCFE

PCode Fuzzing Engine

PCFE is an attempt at creating a JIT'd Pcode emulation engine for fuzzing purposes.

Currently just JIT some code from the provided binary file, call it, and display some register information.

Todo List

• Add big endian support
• Fix the weird bug with branching + optimizations
• Breakpoints
• Coverage callbacks
• Emulator API
  • Python bindings for ease of use
  • Loading snapshots
    • Also may require Sleighcraft modifications

Planned features

• Branch coverage
• Compare coverage
• Tie into LibAFL
• Provide an interface for using with libfuzzer/AFL/hongfuzz

Requirements

• Rust 1.53
• llvm 10.0+

Usage

cargo run <target bin> [-vvvv] [-a ARCH]
