* Code: Generic 32-bit binary operation. Provides an "instr" line to | |
* specify an instruction that performs "%edx = %edx op %cl" | |
* | |
* For: shl-int, shr-int, ushr-int | |
* | |
* Description: Perform a binary operation on two source registers | |
* and store the result in a destination register. | |
* | |
* Format: AA|op CC|BB (23x) | |
* | |
* Syntax: op vAA, vBB, vCC | |
