* Code: Performs a shift left long. Uses no substitutions. | |
* | |
* For: shl-long/2addr | |
* | |
* Description: Perform a binary shift operation using two source registers | |
* where the fist is the value to shift and the second is the | |
* shift amount. Store the result in the first source register. | |
* | |
* Format: B|A|op (12x) | |
* | |
* Syntax: op vA, vB | |
