To the example code, I only change '%eax' to '1234' and it failed!! So what's the assembler? it's not NASM, it's not MASM. I need to know what's it so as to find its document to know about the syntax. Thank you very much. 

My code

I do not do assembly programming, but I'd assume it's the GNU Assembler you're after.

100% correct. Because I tried the example on that Wikipedia page and it worked.
