Imul with one argument
Witrynaimul along with the unsigned mul instruction. The multiplication instructions provide you with another taste of irregularity in the x86-64’s instruction set. Instructions like add sub , and many others in the x86-64 instruction set support two operands, just like the mov instruction.
