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
