§Overview

Ristretto JIT provides a Just-In-Time compiler for the Ristretto VM. The JIT compiler generates native code from Ristretto VM bytecode, allowing for high-performance execution directly on the host machine.

§Architecture

The JIT compiler follows a multi-stage compilation pipeline:

  1. Bytecode Analysis - Analyzes Java bytecode for control flow patterns
  2. Control Flow Graph Construction - Builds a block based control flow graph
  3. SSA Transformation - Converts stack-based operations to Static Single Assignment form
  4. Native Code Generation - Generates optimized machine code
  5. Function Binding - Creates callable native functions

§Features

  • Fast execution through native code generation
  • Automatic optimization of bytecode patterns
  • Control flow graph analysis for complex branching logic
  • Platform-specific compilation for x86-64, aarch64 (ARM64), s390x (IBM Z) and riscv64
  • Comprehensive error handling with detailed error messages

§Platform Support

The JIT compiler automatically adapts to the target platform:

  • Native platforms:
    • x86-64 (Intel/AMD 64-bit)
    • aarch64 (ARM 64-bit)
    • s390x (IBM Z Architecture)
    • riscv64 (RISC-V 64-bit)

§Limitations

Current limitations include:

  • Only static methods and constructors (<init>) are supported
  • Limited object-oriented features (no instance method compilation yet)
  • No garbage collection integration
  • Exception handling is not fully implemented
