About:
Qbe is a lightweight compiler backend designed to serve as a simpler alternative to LLVM. It provides register allocation and machine code generation for multiple architectures, enabling developers to create compilers without the complexity of larger systems.
Key Features:
  • Lightweight and simple design
  • Multiple architecture support (x86_64, ARM64, RISC-V)
  • Integrated register allocator
  • C-based API for easy integration
Use Cases:
  • Building custom programming language compilers
  • Creating domain-specific language (DSL) compilers
  • Educational projects on compiler design
  • Porting existing compilers to lighter backends
Alternatives:
  • LLVM – Much larger and more complex, but with more features and optimizations
  • Cranelift – Similar goals but part of the WebAssembly ecosystem with different focus
