For me, it is necessary. We need disassemble target binary instructions (recognize them), then translate them into tcg instructions which are grouped by Translate Block. We may not need to display the instructions (it is only for test), but we still need recognize them. And for me, current tilera opcode implementation in binutils/kernel is already almost the fewest and the simplestkk. > If you need it you can dump instruction bytes and use the script > scripts/disas-objdump.pl > that calls binutils. target-xtensa does that. > OK, thanks, for me, it is a useful tool.
