vector.AtomicMemoryFlags enum¶
Semantic requirements for atomic memory updates.
Cases¶
| Keyword | Value | Description |
|---|---|---|
root_in_bounds |
8 | Promise that the complete physical access lies within its allocation root. Logical view indices must still be proven in bounds. This carries a source-language access contract through opaque pointer transport and has no target execution semantics. |
noftz |
2 | Preserve subnormal inputs and results of floating-point atomic addition. Without this flag the target may flush subnormals. The selected target must support the requested element width; preservation may require a compare-exchange loop. Returned old values retain their bits with or without this flag. |
