low.LowMemoryAccessFlags enum¶
Physical memory observation semantics for descriptor-backed instructions.
Cases¶
| Keyword | Value | Description |
|---|---|---|
volatile |
1 | Require every dynamic access to execute as an independently observable operation and preserve its order relative to other volatile accesses. A target may decompose one logical access into multiple physical accesses. This does not provide atomicity, synchronization, or a cache-coherence guarantee. |
atomic |
4 | Mark one physical load/store as an indivisible atomic observation. Every dynamic access is observable and same-location issue order is preserved. The instruction and address alignment supply atomicity; explicit fences and cache controls supply synchronization and visibility. Independent addresses do not require ordered completion. |
