架构行为

目的与范围

用途与范围

本单元拥有五个架构可见的数值状态标志，以及成功数值操作之后应用的粘滞更新规则。

概念与架构状态

标志布局

NumericStatusFlags 读取 CORE_STATE[36:32]。从位 36 到位 32，五个标志依次是 NV、DZ、OF、UF 和 NX。

规则与交互

粘滞更新规则

RecordNumericStatusFlags 把给定五位值与当前状态进行 OR，并把结果写回 CORE_STATE[36:32]。

因此，成功的数值操作可以设置标志，但不能清除先前操作已经设置的标志。

边界与未定义范围

架构边界

本所有者定义状态布局和累积操作，但不决定哪个数值操作产生 NV、DZ、OF、UF 或 NX；该决定属于数值操作的当前 ASL 所有者，以及适用时的配置档钩子。

使用示例

示例性粘滞标志示例

如果当前五位状态是 10000，之后一次成功操作提供 00001，记录值将变成 10001。随后提供 00000 时，10001 保持不变。

    Numeric execution flags MUST map to CORE_STATE[36:32] as NV, DZ, OF, UF, and NX, and a successful numeric operation MUST OR its produced flags into the existing sticky status without clearing an earlier flag.
