   Hi
   
   I found https://github.com/vnmakarov/mir?tab=readme-ov-file
   
   It should be significantly faster than llvm (compilation).

   Hello,
   
   I can't tell about JIT, it is too complicated for me ^^
   
   Fwiw, Pierre Ducroquet wrote an article about another (faster) 
   implementation:

   Xing Guo replied to his article by mentioning another two prototypes :
   
   – https://github.com/higuoxing/pg_slowjit
   – https://github.com/higuoxing/pg_asmjit
   
   It is good to see interest in this area. Current implementation is quite 
   expensive and costing model risky. If often recommend disabling it and 
   enabling it when it is really needed. (It is disabled by default on AWS).
