86x64

Convert 32-bit i386 executables to 64-bit x86_64 executables. With macOS 10.15, Apple dropped support for running 32-bit executables under 64-bit macOS.

Development Status

86x64 is still in a highly experimental stage. It can currently translate some simple 32-bit programs to 64 bits -- for examples, see the tests/ directory.

Getting Started

These instructions will guide you through setting up 86x64 on your Mac.
