The movq instruction moves the 1st argument (passed in %rdi) to its place on the stack. The argument occupies the first stack position (stack entries are 8 movq (assuming you're talking about x86) is a move of a quadword (64-bit value). This particular instruction: movq (%rsp), %rsp. For each assembly instruction (e.g. mov, xchg, call, etc.) there are actually multiple machine instructions, depending on the type of operands. //MOVQ instruction when operating on MMX technology registers and memory locations: if(IsMMX(Source) || IsMMX(Destination)) Destination = Source; Since a MOVQ instruction moves two elements from consecutive memory, it is impossible to move, say, b[0][0] and b[1][0] with a single MOVQ with a row-majorMOVQ (Intel x86/64 assembly instruction). ??? : 2020-09-01 ? ?? 813 ? ?????. MOVQ. Move example, moving a quadword from %rax to %rbx results in the instruction movq %rax, %rbx. Some instructions, like ret, do not use suffixes because there is register set and instruction set of the machine. using the sequence: movq a(%rip), %rax; ctqo; idivq b(%rip); movq %rax, c(%rip).
