JIT / recompilation

JIT libraries

• Xbyak looks amazing (x86)
• LLVM: ORC
• GCC: libgccjit
• Might be also useful: libunwind

IR JITs

• Cranelift
• http://themaister.net/blog/2019/01/27/an-unusual-recompiler-experiment-mips-to-llvm-ir-part-1/
• ARM: Citra, Yuzu, EKA2L1 (all the same, for x86_64 & ARM64)
• LuaJIT’s DynASM; great writeup: https://github.com/sysprog21/jitboy
• PCSX2 https://github.com/PCSX2/pcsx2/blob/master/pcsx2/x86/microVU_Compile.inl
• https://wiki.mozilla.org/Tamarin:Tracing
• https://github.com/pcercuei/lightrec: MIPS-to-everything dynamic recompiler for PSX emulators
• NanoJIT? Unmaintained.
