## Instruction MOV MOV is renamed as MVR and MOV, DEC, and INC become pseudos using MVR ### Before: |`MOV`| `D, S` | `XXXXXXXXSSDD0000` | Move value at source register to destination register| ### After: |`MVR`| `D, S, V` | `VVVVVVVVSSDD0000` | Add sign-extended immediate value to value at source register and move it to destination register| |`MOV`| `D, S` | `00000000SSDD0000` | Move value at source register to destination register| |`INC`| `D` | `00000001DDDD0000` | Increment value at destination register| |`DEC`| `D` | `11111111DDDD0000` | Decrement value at destination register| Retro-compatibility is kept for assembly code, not for machine code.
## Instruction LDV LDV is renamed as MVV and LDV, MVI, ADI, MUI and AUI become pseudos using MVV ### Before: |LDV| D, V | VVVVVVVVVVDD0001 | Load a value into destination register. ### After: |LDV| D, V, O | VVVVVVVVOODD0001 | Load a value into destination register. |MVI| D, V | VVVVVVVV00DD0001 | Set a zero-extended lower byte to destination register. |ADI| D, V | VVVVVVVV01DD0001 | Set a zero-extended lower byte to destination register. |MUI| D, V | VVVVVVVV10DD0001 | Set a byte left shifted by 8 bits to destination register. |AUI| D, V | VVVVVVVV11DD0001 | Add a byte left shifted by 8 bits to destination register.
