ARM64 内部函数
Microsoft C++ 编译器 (MSVC) 使以下内部函数在 ARM64 体系结构上可用。 有关 ARM 的详细信息，请参阅 ARM 开发人员文档网站的体系结构和软件开发工具部分。
NEON
适用于 ARM64 的 NEON 矢量指令集扩展提供 Single Instruction Multiple Data (SIMD) 功能。 它们类似于 x86 和 x64 体系结构处理器通用的 MMX 和 SSE 矢量指令集中的指令集。
根据头文件 arm64_neon.h，霓虹灯内部函数受到支持。 MSVC 对 NEON 内部函数的支持类似于 ARM64 编译器，ARM 信息中心网站上的 ARM NEON 内部函数参考中对此进行了记录。

内存屏障限制
内部函数 __dmb（数据内存屏障）、__dsb（数据同步屏障）和 __isb（指令同步屏障）使用以下预定义值以根据共享域和受操作影响的访问类型对内存屏障限制进行指定。
| 限制值 | 说明 |
|---|---|
| _ARM64_BARRIER_SY | 完整系统，读取和写入操作。 |
| _ARM64_BARRIER_ST | 完整系统，只写操作。 |
| _ARM64_BARRIER_LD | 完整系统，只读操作。 |
| _ARM64_BARRIER_ISH | 内部可共享，读取和写入操作。 |
| _ARM64_BARRIER_ISHST | 内部可共享，只写操作。 |
| _ARM64_BARRIER_ISHLD | 内部可共享，只读操作。 |
| _ARM64_BARRIER_NSH | 不可共享，读取和写入操作。 |
| _ARM64_BARRIER_NSHST | 不可共享，只写操作。 |
| _ARM64_BARRIER_NSHLD | 不可共享，只读操作。 |
| _ARM64_BARRIER_OSH | 外部可共享，读取和写入操作。 |
| _ARM64_BARRIER_OSHST | 外部可共享，只写操作。 |
| _ARM64_BARRIER_OSHLD | 外部可共享，只读操作。 |
对于 __isb 内部函数，当前有效的唯一限制是 _ARM64_BARRIER_SY；其他所有值由体系结构进行保留。
__iso_volatile_load/store 内部函数
这些内部函数显式执行不进行编译器优化的加载和存储。
__int16 __iso_volatile_load16(const volatile __int16 * Location);
__int32 __iso_volatile_load32(const volatile __int32 * Location);
__int64 __iso_volatile_load64(const volatile __int64 * Location);
__int8 __iso_volatile_load8(const volatile __int8 * Location);
void __iso_volatile_store16(volatile __int16 * Location, __int16 Value);
void __iso_volatile_store32(volatile __int32 * Location, __int32 Value);
void __iso_volatile_store64(volatile __int64 * Location, __int64 Value);
void __iso_volatile_store8(volatile __int8 * Location, __int8 Value);
参数
位置
要从中读取或为其写入的内存位置的地址。
值
要写入指定内存位置的值（仅存储内部函数）。
返回值（仅加载内部函数）
由 Location 指定的内存位置的值。
注解
你可以使用 __iso_volatile_load8/16/32/64 和 __iso_volatile_store8/16/32/64 内部函数显式执行不进行编译器优化的内存访问。 编译器无法删除、合成或更改这些操作的相对顺序。 但是，它不会生成隐式硬件内存屏障。 因此，硬件仍可能对跨多个线程的可观察内存访问进行重新排序。 更准确地说，这些内部函数等效于在 /volatile:iso 下编译的以下表达式。
int a = __iso_volatile_load32(p); // equivalent to: int a = *(const volatile __int32*)p;
__iso_volatile_store32(p, a); // equivalent to: *(volatile __int32*)p = a;
请注意内部函数采用易失性指针来适应易失性变量。 但是，没有关于使用可变指针作为参数的要求或建议。 如果使用常规的非易失类型，这些操作的语义完全相同。
有关 /volatile:iso 命令行参数的详细信息，请参阅 /volatile（volatile 关键字解释）。
ARM64 支持来自其他体系结构的内部函数

互锁内部函数
互锁内部函数是用于执行原子读取-修改-写入操作的一组内部函数。 其中一些互锁内部函数通用于所有平台。 因为它们数量很多，所以在这里单独列出。 由于它们的定义大多是冗余的，因此，用一般术语来考虑更加容易。 它们的名称可用于派生确切行为。
下表总结了非 bittest 互锁内部函数的 ARM64 支持。 表中的每个单元格都对应一个名称，这些名称的派生方式是将该行的最左侧单元格中的操作名和该列的最上面单元格中的类型名附加到 _Interlocked。 例如，第 Xor 行和第 8 列交叉处的单元格对应于 _InterlockedXor8 并且完全受支持。 大部分受支持的函数提供以下可选后缀：_acq、_rel 和 _nf。 _acq 后缀表示“获取”语义，而 _rel 后缀表示“发布”语义。 _nf 或“no fence”后缀是 ARM 和 ARM64 独有的，将在下一节中进行讨论。
| Operation | 8 | 16 | 32 | 64 | 128 | P |
|---|---|---|---|---|---|---|
| 添加 | 无 | 无 | 完全 | 完全 | 无 | 无 |
| 且 | 完全 | 完全 | 完全 | 完全 | 无 | 无 |
| CompareExchange | 完整 | 完全 | 完全 | 完全 | 完全 | 完全 |
| 递减 | 无 | 完全 | 完全 | 完全 | 无 | 无 |
| Exchange | 完全 | 完全 | 完全 | 完全 | 无 | 完全 |
| ExchangeAdd | 完整 | 完全 | 完全 | 完全 | 无 | 无 |
| 增量 | 无 | 完全 | 完全 | 完全 | 无 | 无 |
| 或 | 完全 | 完全 | 完全 | 完全 | 无 | 无 |
| Xor | 完全 | 完全 | 完全 | 完全 | 无 | 无 |
密钥:
完全：支持普通、
_acq、_rel和_nf窗体。无：不支持
_nf (no fence) 后缀
_nf 或“no fence”后缀表示操作不表现为任何类型的内存屏障，与表现为某种类型屏障的其他三种形式（无格式、_acq 和 _rel）相反。 _nf 形式的一种可能用途是维护统计信息计数器，该计数器由多个线程同时更新，但在执行多个线程时不会使用该计数器的值。

_interlockedbittest 内部函数
纯互锁的 bit 测试内部函数通用于所有平台。 ARM64 添加了 _acq、_rel 和 _nf 变体，它们只是修改操作的屏障语义，如本文前面的 _nf (no fence) 后缀中所述。
