LoongArch instructions are 32 bits wide, belonging to 9 basic instruction formats (and variants of them):

| Format name  | Composition                 |
| 2R           | Opcode + Rj + Rd            |
| 3R           | Opcode + Rk + Rj + Rd       |
| 4R           | Opcode + Ra + Rk + Rj + Rd  |
| 2RI8         | Opcode + I8 + Rj + Rd       |
| 2RI12        | Opcode + I12 + Rj + Rd      |
| 2RI14        | Opcode + I14 + Rj + Rd      |
| 2RI16        | Opcode + I16 + Rj + Rd      |
| 1RI21        | Opcode + I21L + Rj + I21H   |
| I26          | Opcode + I26L + I26H        |

Rd is the destination register operand, while Rj, Rk and Ra (“a” stands for “additional”) are the source register operands.
I8/I12/I14/I16/I21/I26 are immediate operands of respective width. The longer I21 and I26 are stored in separate higher and
lower parts in the instruction word, denoted by the “L” and “H” suffixes. */
