ARM64 內建

Microsoft C++ 編譯程式 (MSVC) 可在 ARM64 架構上使用下列內部函數。 如需 ARM 的詳細資訊,請參閱 ARM 開發人員文件網站的架構和軟體開發工具章節

ARM64 的 NEON 向量指令集延伸模組提供單一指令多個資料 (SIMD) 功能。 它們類似於MMX和SSE向量指令集中常見的 x86 和 x64 架構處理器。

支援 NEON 內建函式,並提供於標頭檔 arm64_neon.h 中。 NEON 內部函數的 MSVC 支援類似於 ARM64 編譯程式,該編譯程式記載於 ARM Infocenter 網站上的 ARM NEON 內建參考 中。

記憶體屏障限制

內部函 __dmb 式(數據記憶體屏障)、 __dsb (資料同步屏障)和 __isb (指令同步處理屏障)會使用下列預先定義的值來指定共用網域的記憶體屏障限制,以及受作業影響的存取類型。

限制值 描述
_ARM64_BARRIER_SY 完整系統,讀取和寫入。
_ARM64_BARRIER_ST 完整系統,只寫入。
_ARM64_BARRIER_LD 完整系統,唯讀。
_ARM64_BARRIER_ISH 可內部共用,讀取和寫入。
_ARM64_BARRIER_ISHST 可內部共用,只寫入。
_ARM64_BARRIER_ISHLD 內部可共用,只讀。
_ARM64_BARRIER_NSH 不可共用,讀取和寫入。
_ARM64_BARRIER_NSHST 不可共用,只寫入。
_ARM64_BARRIER_NSHLD 不可共用、唯讀。
_ARM64_BARRIER_OSH 可外部共用,讀取和寫入。
_ARM64_BARRIER_OSHST 可外部共用,只寫入。
_ARM64_BARRIER_OSHLD 外部可共用,只讀。

__isb對於內部函數,目前唯一有效的限制是_ARM64_BARRIER_SY;所有其他值都會由架構保留。

__iso_volatile_load/存放內部函數

這些內部函數會明確執行不受編譯程式優化影響的載入和存放區。

__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);

參數

地點
要讀取或寫入的記憶體位置的位址。

ReplTest1
要寫入指定記憶體位置的值(僅儲存內部函數)。

傳回值(僅載入內部函數)

Location指定的記憶體位置值。

備註

您可以使用 __iso_volatile_load8/16/32/64__iso_volatile_store8/16/32/64 內建來明確執行不受編譯程式優化影響的記憶體存取。 編譯程式無法移除、合成或變更這些作業的相對順序。 不過,它不會產生隱含的硬體記憶體屏障。 因此,硬體可能仍然重新排列跨多個執行緒中可觀察到的記憶體存取。 更精確地說,這些內部函數相當於在 /volatile:iso編譯的下列表達式。

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;

請注意,內建函式採取暫時性 (volatile) 指標以容納暫時性變數。 不過,不需要或建議使用揮發性指標作為自變數。 如果使用一般、非揮發性型別,這些作業的語意就完全相同。

如需 /volatile:iso 命令行自變數的詳細資訊,請參閱 /volatile (volatile 關鍵詞解譯)

內建聯結

連鎖內建函式是一組內建函式,用來執行不可部分完成的讀取-修改-寫入作業。 其中有部分通用於所有平台。 它們會分別列在這裡,因為有大量的它們。 因為它們的定義大多是多餘的,所以一般情況下更容易思考它們。 它們的名稱可以用來得出確切的行為。

下表摘要說明非位聯結內部函數的ARM64支援。 在表中的每個儲存格對應的名稱,是將列的最左邊儲存格的作業名稱,和欄的最上方儲存格的類型名稱,附加至 _Interlocked 所衍生的名稱。 例如,數據列和數據行交集 Xor 處的 8 單元格會對應至 _InterlockedXor8 且完全支援。 大部分受支援的函式會提供這些選擇性的字尾:_acq_rel_nf_acq 字尾表示「取得」語意,_rel 字尾表示「釋放」語意。 _nf或 「無柵欄」後綴對 ARM 和 ARM64 而言是唯一的,下一節會討論。
