xrop is a simple tool to generate ROP gadgets. It supports PE, ELF, Mach-O and perhaps other executable formats. It uses the libxdisasm library and currently supports generating ROP gadgets for x86, x86_64, arm, ppc, mips, riscv, sh4 and sparc.

On macos there is a Homebrew tap available:

brew tap acama/homebrew-xrop
brew install xrop

On other systems, you need to build from source as of now:

git clone https://github.com/acama/xrop.git
cd xrop
git submodule update --init --recursive
make
sudo make install # will install in /opt/xrop

• v1.2 - macos (apple silicon) support.
• v1.1 - call gadgets, jmp gadgets, printing instruction opcodes.
