在nasm的宏asm中声明局部变量的方法就像：％local old_ax：word，以及在masm的宏asm中声明局部变量的方式就像：local old_ax：WORD，那么是什么＆＃39; s如何在宏观的天然气中声明局部变量？

gas

但一般来说，你可以直接使用equates for stack offsets，例如：

.intel_syntax noprefix
.globl main

.macro local head, tail:vararg
# assume dwords for simplicity
.set localsize, localsize + 4
.set \head, -localsize
.ifnb \tail
local \tail
.endif
.endm

main:
    .set localsize, 0
    local old_ax, old_dx
    enter localsize, 0
    mov [ebp+old_ax], ax
    mov [ebp+old_dx], dx
    leave
    ret

如何在宏观asm中声明局部变量，就像在宏观asm中使用％local在macrom的asm中或在masm的宏asm中本地声明一样？
