C++ 通过编译器宏确定当前的CPU指令集平台，如IBM S390X（PowerPC64)

这是一个存宏判断实现的函数，用来获取平台的指令集代码类型。?

    const char* GetPlatformCode() noexcept {
#if defined(__x86_64__) || defined(_M_X64)
        return "x86_64";
#elif defined(i386) || defined(__i386__) || defined(__i386) || defined(_M_IX86)

#elif defined(__ARM_ARCH_3__) || defined(__ARM_ARCH_3M__)
        return "ARM3";

        return "ARM4T";
#elif defined(__ARM_ARCH_5_) || defined(__ARM_ARCH_5E_)
        return "ARM5"
#elif defined(__ARM_ARCH_6T2_) || defined(__ARM_ARCH_6T2_)
        return "ARM6T2";
#elif defined(__ARM_ARCH_6__) || defined(__ARM_ARCH_6J__) || defined(__ARM_ARCH_6K__) || defined(__ARM_ARCH_6Z__) || defined(__ARM_ARCH_6ZK__)
        return "ARM6";
#elif defined(__ARM_ARCH_7__) || defined(__ARM_ARCH_7A__) || defined(__ARM_ARCH_7R__) || defined(__ARM_ARCH_7M__) || defined(__ARM_ARCH_7S__)
        return "ARM7";

#elif defined(__s390x__)
        return "S390X";
#else
        return "UNKNOWN";
#endif
    }
