The source and destination operands can be MMX™ technology registers, XMM registers, or 64-bit memory locations. This instruction can be used to move a between This instruction can be used to move a doubleword to and from the low doubleword of an MMX technology register and a general-purpose register or a 32-bit The MMX instructions enable x86 processors to perform single-instruction, multiple-data(SIMD) movq. MOVQ. move quadword. valid only under -m64 x64 assembly code uses sixteen 64-bit registers. example, moving a quadword from %rax to %rbx results in the instruction movq %rax, %rbx. 9: 89 3e mov. %edi,(%rsi) b: c3 retq. Original Code. Compiler Output. (Machine code & Assembly). Notice how each instruction is.movq (assuming you're talking about x86) is a move of a quadword (64-bit value). This particular instruction: movq (%rsp), %rsp. This instruction can be used to move a quadword between two MMX technology registers or between an MMX technology register and a 64-bit memory location, or to 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 x86 Instruction Set Reference. MOVQ.
