将C程序转换为IA32程序集（非常快）

Question

Just have one little thing I got stuck on while translating this C code into assembly. This is the line of code I am stuck on.

if (input == '\n')

My assembly code thus far(for this line) is

movl input, %eax    #%eax = input
cmpl ___, %eax

How do I compare input to '\\n'? Do I just compare it outright or do I move it into the memory first? Thanks.

Answer 1

Try

cmp 0x0D,%eax

0x0D is the ascii code for carriage return, or you can try 0x0A for line feed.

Answer 2

直接比较它， cmp允许立即值。
