Currently, MIPS and ARM use capstone disassembler. If we can use this for ARMv7, it simplifies the implementation. I don't want to use capstone for X86, X86_64, and ARM64 right now since these instruction sets are really changing: new instructions are added frequently. So I would like to have our own ones in the tree. But for MIPS, ARM and ARMv7, instruction sets are not so changed in terms of our JIT.
