Thank you all for the comments.
I didn't know this document.
In fact, this patch match with tables entries seen in it:

| Instruction | Operands | Ops | Latency | Reciprocal throughput | Execution unit | Notes |
|-------------|------------|------|----------|--------------------------|-----------------|--------|
| MOV | r,r | 1 | 1 | 1/3 | ALU |
| MOV | r,i | 1 | 1 | 1/3 | ALU |

Some of additional information are in this patch:
- `Instruction + operands`: LLVM Opcode Name.
- Execution unit

Adding bypass latency.

I am going to write these informations only when -instruction-tables is on.
