Umm. IMHO The existing JIT is not well designed, with
processor-specific constants everywhere and "optimizations" such as
inlinining huge blocks of weakly-optimized code instead of making a
function call to properly-optimized code.


These issues make it difficult to both port and maintain.


If the other JIT is better designed than the current one, IMHO it should be considered for inclusion.
