Simple inline assembly program won't compile

This is driving me insane... I'm sure there's something very small I'm doing wrong here, but I can't figure out what it is after trying for 30 minutes and go开发者_如何学Pythonogling. I am trying to compile a very simple C program with some inline assembly, then disassemble it, in order to get the machine code for the instructions. This is for a school programming project. Here is my most recent attempt:

int main() 
{
asm(
    "movl   $0x5bc1229f,0x0804c1e8"
    "movl   $0x08048f9c,%edx"
    "push   %edx"
    "ret"
      );
}

When I compile this, I get the errors:

/var/folders/kI/kIAe03vJFdClYy0r0mmBp++++TI/-Tmp-//cc2xKnoz.s:9:junk `movl $0x08048f9c' after expression

/var/folders/kI/kIAe03vJFdClYy0r0mmBp++++TI/-Tmp-//cc2xKnoz.s:9:bad register name `%edxpush%edxret'

Thanks for your help :)

Try

int main()
{
asm(
    "movl   $0x5bc1229f,0x0804c1e8\n\t"
    "movl   $0x08048f9c,%edx\n\t"
    "push   %edx\n\t"
    "ret\n\t"
      );
}
