FARA (FARA Research Architecture)

A custom Instruction Set Architecture (ISA) with a simulator written in Rust and a custom LLVM backend for code generation.

• 64bit instruction set with 24 general purpose integer register
• RISC architecture (no complex indirect adressing mode etc.)

Initial documentation is in the doc/ directory.

LLVM backend

An LLVM backend for the ISA is developed here: https://github.com/fotcorn/fara-llvm-backend

Current features of the backend:

• Machine code generation from assembly
• Instruction selection for simple C programs
• Basic setup in Clang to support C programs
• Linker support for ELF files in LLD
