What's the difference between the RISCV-J-extension and MCJIT #4

Hi dear everyone, The new proposal RISCV-J-extension stands for the role of JIT compiling as the README.md says, but as far as I know, there are JIT, MCJIT and OrcJIT [1], what's your advantages for taking placing of them?

Best Regards Many thanks William

The J Extension group does not replace any specific JIT but instead is working on RISC-V instruction set standards that are related to better supporting JIT compilers, interpreters, etc. Specifically, the group is currently developing two standards: pointer masking and instruction/data consistency.
