On `sm_89`, `ptxas` already fuses 3-input `HH(x,y,z) = x ^ y ^ z` into a single hardware `LOP3.LUT Rd, Ra, Rb, Rc, 0x96` instruction; factoring `tbc_s` and `tda_s` in PTX still requires one bitwise instruction per step in SASS (`562` unpadded SASS insts, `114` `LOP3.LUT`, `39` regs — identical to `eq8_diam`).\n\n---\n\n## 3.
