Arithmetic bug
one for unsigned (mulq) and one for two’s-complement (imulq) multiplication.For both of these instructions, one argument must be in register %rax, and theother is given as the instruction source operand.
mulq 和 imulq 分别表示什么指令集,他们的操作数有什么要求?
LSB (least significant bit): The rightmost bit MSB (most significant bit): The leftmost bit
This only applies to Little-endian architecture. Big-endian is reversed.
