| * Code: 32-bit "lit8" divide operation. Provides an "instr" line | |
| * to specify an instruction that performs "%edx = %edx op %cl" | |
| * | |
| * | |
| * For: shl-int/lit8, shr-int/lit8, ushr-int/lit8 | |

| * Description: Perform a binary operation on a register and a | |
| * signed extended 8-bit literal value | |
| * | |
| * Format: AA|op CC|BB (22b) | |
| * | |
| * Syntax: op vAA, vBB, #+CC | |
