Thank you very much, is this code OK?
case OPC_REPL_OB:
check_dsp(ctx);
{
target_long temp;
imm = (ctx->opcode >> 16) & 0xFF;
temp = ((uint64_t)imm << 56) | ((uint64_t)imm << 48) |
((uint64_t)imm << 40) | ((uint64_t)imm << 32) |
((uint64_t)imm << 24) | ((uint64_t)imm << 16) |
((uint64_t)imm << 8) | (uint64_t)imm;
tcg_gen_movi_tl(cpu_gpr[ret], temp);
break;
