x386，有没有办法使用另一个寄存器推送？(x386, Is there a way to PUSH using another register?)

x386，有没有办法使用另一个寄存器推送？(x386, Is there a way to PUSH using another register?)

我的意思是当你做PUSH 10 ，它类似于DEC ESP; MOVE [ESP], 10 DEC ESP; MOVE [ESP], 10

但有没有办法做DEC EDX; MOV [EDX], 10 DEC EDX; MOV [EDX], 10合一命令？ 和其他寄存器一样，EDX，EAX ......

I mean when you do PUSH 10, it is similar to DEC ESP; MOVE [ESP], 10

but is there a way to do DEC EDX; MOV [EDX], 10 in one command? and same for other registers, EDX, EAX...

std mov EDI, offset ... mov AL, 10 ; Single instruction (save AL to ES:EDI, post-decrement of EDI) stosb std mov EDI, offset ... mov AL, 10 ; Single instruction (save AL to ES:EDI, post-decrement of EDI) stosb
