| `-s` or `--symbol` | Symbol or list of symbols to be mutated. This requires a linked `.map` file. | :x: |
| `--map` | Map file to be linked. IDA Pro `.map` files must have their extension replaced with `.ida`. | :x: |
| `--list` | List of functions to be mutated. Each entry must envelop one line and be formatted as `0x1000:0x2000` where `0x1000` is the start and `0x2000` is the end of the routine. | :x: |
| `--x64` | Used to indicate that the file is of 64bit architecture (AMD64). | :heavy_check_mark: |
| `--rets` | Allow PERSES to build a `RET` gadget pool used to create `JMP`s to random locations. | :x: |
| `--scan` | Force PERSES to scan for code protection markers. | :x: |
