Purpose

SLJIT is a low-level, platform-independent JIT compiler, which is very well suited for translating bytecode into machine code.

Features

• Supports a variety of target architectures:
  • x86 32 / 64
  • ARM 32 / 64
  • RISC-V 32 / 64
  • s390x 64
  • PowerPC 32 / 64
  • LoongArch 64
  • MIPS 32 / 64
• Supports a large number of operations
  • Self-modifying code
  • Tail calls
  • Fast calls
  • Byte order reverse (endianness switching)
  • Unaligned memory accesses
  • SIMD
  • Atomic operations
• Allows direct access to registers (both integer and floating point)
• Supports stack space allocation for function local variables
• Supports all-in-one compilation
  • Allows SLJIT's API to be completely hidden from external use
• Allows serializing the compiler into a byte buffer
  • Useful for ahead-of-time (AOT) compilation
  • Code generation can be resumed after deserialization (partial AOT compilation)
