For LoongArch64's ISA which is same with the MIPS64 ISA, even the instructions of 32bits operation need the upper 32bits be sign-extended to 64 bits.（对于与MIPS64 ISA相同的LoongArch64 ISA，即使是32位操作的指令也需要将高位32位符号扩展为64位。）
我怀疑是不是XLX的混进去写代码了
https://docs.kernel.org/arch/loongarch/introduction.html 已经明确表明“LoongArch is a RISC ISA which is different from any other existing ones（LoongArch是不同于任何现有指令集的RISC ISA）”
