                     FT-JIT Compiler

Purpose:
  A low-level, machine independent JIT compiler, which is suitable for
  translating interpreted byte code into machine code. The ft_jit_Lir.h
  describes the LIR (low-level intermediate representation) of FT_JIT.

Key features:
  - Supports several target architectures:
    x86 32/64, ARM 32/64, RiscV 32/64, s390x 64,
    PowerPC 32/64, LoongArch 64, MIPS 32/64
  - Supports a large number of operations
    - Supports self-modifying code
    - Supports tail calls
    - Support fast calls (non-ABI compatible)
    - Supports byte order reverse (endianness switching)
    - Supports unaligned memory accesses
    - Supports SIMD / atomic operations on certain CPUs
  - Direct register access, both integer and floating point
  - Stack space allocated for function local variables can be
    accessed as a linear memory area
  - All-in-one compilation is supported
  - When ft_jit_Lir.c is directly included by a C source file,
    the jit compiler API can be completely hidden from
    external use (see FT_JIT_CONFIG_STATIC macro)
    - Code can be generated for multiple target cpus
      by including ft_jit_Lir.c in different C files, where
      each compiler instance is configured to target a
      different architecture
  - The compiler can be serialized into a byte buffer
    - Useful for ahead-of-time compiling
    - Code generation can be resumed after deserialization
      (partial ahead-of-time compiling)

Compatible:
  C99 (C++) compilers.

Using sljit:
  Copy the content of ft_jit_src directory into your project source directory.
  Add ft_jit_Lir.c source file to your build environment. All other files are
  included by ft_jit_Lir.c (if required). Define the machine by FT_JIT_CONFIG_*
  selector. See ft_jit_ConfigCPU.h for all possible values. For C++ compilers,
  rename ft_jit_Lir.c to ft_jit_Lir.cpp.
