According to ARM's documentation, the mandatory features added in armv9.2-a compared to armv9-a cannot be directly used in userspace. Therefore, in principle, armv9.2-a builds should run on armv9-a hardware, but I cannot guarantee this. I added -msve-vector-bits=128 to armv9.2-a builds to enhance SVE automatic vectorization, but it will not run on future 256-bit hardware. If 256-bit hardware does become available in the future, I will add a new 256-bit build.
Since there are currently no real Windows devices with SVE2, armv9.2-a builds have not been rigorously tested and may not work at all, but I did perform a simple verification using wine.
