I don't think that's accurate. These vector instructions are defined (by the vendor) and were intended to be accessible; the problem is that they have unexpected and insecure behavior.
- dzaima 2y agoThe instruction in question doesn't map to any instruction in neither RVV0.7.1/xtheadvector, nor RVV1.0. Disassemblers don't disassemble it, and assemblers don't have any mnemonic for it (the 'vse128.v' used by the authors is essentially arbitrary afaict; and even if it weren't, there's zero reason to think that C910 had any intention of supporting 128-bit elements)
