================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfoV.td:99
 // load vd, (rs1), vm
 class VUnitStrideLoad<RISCVMOP mop, RISCVLSUMOP lumop, RISCVWidth width,
                         string opcodestr>
----------------
I believe that with the changes introduced in the encoding of the loads and stores we can do without the `mop` parameter in most of the classes here:

| class   | replace `mop` by   |
|-------|----------------------|
| `VUnitStrideLoad` | `MOPLDUnitStride` (i.e. `00`) |
| `VStridedLoad` | `MOPLDStrided` (i.e. `10`) |
| `VIndexedLoad` | `MOPLDIndexed` (i.e. `11`) |
| `VUnitStrideStore` | `MOPSTUnitStride` (i.e. `00`) |
| `VStridedStore` | `MOPLDStrided` (i.e. `10`) |

We still need to keep the parameter for the `VIndexedStore` class since it can take `MOPSTIndexedOrder` (i.e. `11`) or `MOPSTIndexedUnord` (i.e. `01`).

Does this make sense to you?
