> Also, do you have an example for such "opportunistic" usages? The simplest example would be copying a small number of bytes (like, copying structs). Vector instructions generally have a higher setup cost, like setting so it can't really be used for this purpose. Maybe future vector instructions have no such caveats and can be used as like SIMD, but AFAIK it's not yet the case even for RISC-V's V extension. |
