RaccoonV - A Risc-V JOP gadget finder

RaccoonV is a linux command line tool. It has many advantages compared to a real raccoon: Insead of digging holes in your garden to find food, it will investigate binaries to find JOP gadgets.

Another advantage is that it is made out of Rust instead of legs, snouts and stuff like this. This makes it more robust than a real raccoon, indeed.

⚠️ It only works on Linux for elf binaries with Risc-V architecture (ISA RV32IC).
