* Code: Performs a shift left long. Uses no substitutions. | |
* | |
* For: shl-long | |
* | |
* Description: Perform a binary shift operation using two source registers | |
* where one is the shift amount and the other is the value to shift. | |
* Store the result in a destination register. | |
* | |
* Format: AA|op CC|BB (23x) | |
* | |
* Syntax: op vAA, vBB, vCC | |
