>>1The worst part is the P at the beginning, it's utterly meaningless, since just about every instruction a CPU does is ``performing" some kind of operation. We don't have PMUL, PADD, PJMP, or PCALL instructions, even though we most certainly do ``perform" multiplications, additions, jumps, and function calls. Other than that, we should just drop the data size suffixes and let the assembler figure them out. CLMUL is a perfectly workable instruction mnemonic.
