It includes: 1. guest regiser using bug in tcg_out_qemu_ld and tcg_out_qemu_st 2. immediate range bug in tcg_out_opc_imm 3. a wrong optimization in tcg_out_addsub2 After this patch set, I can run the 400.perlbench case(spec2006-simple). Besides, it seems that we can also run RISU on qemu-aarch64(risc-v) now. I try to run RISU on qemu-aarch64(x86) and qemu-aarch64(risc-v). But this caused an segment fault. And it's confusing that RISU running on two qemu-aarch64(x86-64) also caused a segment fault.
