Shouldn't the mask be 0x3F? As stated in the book, shift instructions only use first m bits of the register %cl, where m depends on the word size specified for the instruction, with the formula 2^m = w. So for salq, w = 64, which gives us m = 6, hence we only take first 6 bits of the n argument. |

On my textbook, line 10 of the assembly code says "salq %cl, %rdx" and hence the reason for my pull request
